Sport Utility Vehicle

G Warning!This Sport Utility Vehicle is designed for bothon-road and off-road use. It can go places andperform tasks for which conventional 2-wheeldrive passenger cars are not intended. Thisvehicle will handle and maneuver differentlyfrom conventional passenger cars in drivingconditions which may occur on streets,highways and off-road use.This vehicle has a higher ground clearanceand a higher center of gravity than manypassenger cars. As with other vehicles of thistype, if you make sharp turns at excessivespeeds or abrupt maneuvers, the vehicle mayroll over or may go out of control and crash.Utility vehicles have a significantly higherrollover rate than other types of vehicles.Failure to operate this vehicle safely mayresult in an accident, rollover of the vehicle,and severe or fatal injury.Before you start to drive this vehicle, read theOperator’s Manual. Take time to becomefamiliar with the driving characteristics of thisvehicle. Be sure you are familiar with allvehicle controls. Learn how your vehiclehandles on different road surfaces. Do notattempt sharp turns at excessive speeds orabrupt maneuvers or other unsafe drivingactions that can cause loss of vehicle control.When driving off-road or working the vehiclehard, do not overload it. And, always wearyour seat belts at all times. In a rollover crash,an unbelted person is significantly more likelyto die than a person wearing a seat belt.

Occupant safety

IntroductionIn this section you will learn the mostimportant facts about the restraint systemcomponents of the vehicle.The restraint systems are:RSeat beltsRChild restraintsRLower Anchors and Tethers for CHildren

(LATCH)Additional protection potential is provided by:RSupplemental Restraint System (SRS) with

- Air bags- Air bag control unit (with crash sensors)- Emergency Tensioning Device (ETD) for

seat belts- Seat belt force limiter

RNECK-PRO active front head restraintsRPreventive occupant safety (PRE-SAFE®)RAir bag system components with

- Front passenger front air bag offindicator lamp

- USA only: Front passenger seat withOccupant Classification System (OCS)

- Canada only: Front passenger seat withBabySmart™ air bag deactivation system

Although the systems are independent, theirprotective functions work in conjunction witheach other.

G Warning!Modifications to or work improperlyconducted on restraint system componentsor their wiring, as well as tampering withinterconnected electronic systems, can leadto the restraint systems no longer functioningas intended.Air bags or Emergency Tensioning Devices(ETDs), for example, could deployinadvertently or fail to deploy in accidentsalthough the deceleration threshold for airbag deployment is exceeded. Therefore,never modify the restraint systems. Do nottamper with electronic components or theirsoftware.

i See “Children in the vehicle”(Y page 55) for information onRinfants and children traveling with you in

the vehicleRrestraint systems for infants and children

For your safety, we strongly recommend thatyou contact an authorized Mercedes-BenzCenter immediately to have the systemchecked. Otherwise the SRS may not beactivated when needed in an accident, whichcould result in serious or fatal injury. The SRSmight also deploy unexpectedly andunnecessarily which could also result in injuryas well.In addition, improper work on the SRS createsa risk of rendering the SRS inoperative orcausing unintended air bag deployment. Workon the SRS must therefore only be performedby qualified technicians. Contact anauthorized Mercedes-Benz Center.If it is necessary to modify an air bag systemto accommodate a person with disabilities,contact an authorized Mercedes-Benz Center.USA only: Call our Customer AssistanceCenter at 1-800-FOR-MERCedes(1-800-367-6372) for details.

Air bags

G Warning!Air bags are designed to reduce the potentialof injury and fatality in certainRfrontal impacts (front air bags and driver’s

side knee bag)Rside impacts (side impact air bags and

window curtain air bags)Rrollovers (window curtain air bags)

However, no system available today cancompletely eliminate injuries and fatalities.

Deployment of the air bags temporarilyreleases a small amount of dust from the airbags. This dust, however, is neither harmfulto your health, nor does it indicate a fire in thevehicle. The dust might cause sometemporary breathing difficulty for people withasthma or other breathing trouble. To avoidthis, you may wish to get out of the vehicle assoon as it is safe to do so. If you have anybreathing difficulty but cannot get out of thevehicle after the air bag inflates, then get freshair by opening a window or door.

G Warning!To reduce the risk of injury when the front airbags inflate, it is very important for the driverand front passenger to always be in a properlyseated position and to wear their respectiveseat belt.For maximum protection in the event of acollision always be in normal seated positionwith your back against the seat backrest.Fasten your seat belt and make sure it isproperly positioned on your body.Since the air bag inflates with considerablespeed and force, a proper seating positionand correct positioning of the hands on thesteering wheel will help to keep you at a safedistance from the air bag. Occupants who arenot wearing their seat belt, are not seatedproperly or are too close to the air bag can beseriously injured or killed by an air bag as itinflates with great force instantaneously:RSit with the seat belt properly fastened in a

position that is as upright as possible withyour back against the seat backrest.RMove the driver’s seat as far back as

possible, still permitting proper operationof vehicle controls. The distance from thecenter of the driver’s chest to the center ofthe air bag cover on the steering wheelmust be at least 10 inches (25 cm) or more.You should be able to accomplish this byadjusting the seat and steering wheel. If

you have any difficulties, please contact anauthorized Mercedes-Benz Center.RDo not lean your head or chest close to the

steering wheel or dashboard.RKeep hands on the outside of the steering

wheel rim. Placing hands and arms insidethe rim can increase the risk and potentialseverity of hand/arm injury when the driverfront air bag inflates.RAdjust the front passenger seat as far as

possible rearward from the dashboardwhen the seat is occupied.ROccupants, especially children, should

never place their bodies or lean their headsin the area of the door where the sideimpact air bag inflates. This could result inserious injuries or death should the sideimpact air bag be deployed. Always sit asupright as possible, wear the seat beltproperly and use an appropriately sizedinfant restraint, toddler restraint, orbooster seat recommended for the size andweight of the child.RCanada only: Children 12 years old and

under must never ride in the front seat,except in a Mercedes-Benz authorizedBabySmart™ compatible child seat, whichoperates with the BabySmart™ air bagdeactivation system installed in the vehicleto deactivate the front passenger front airbag when it is installed properly. Otherwisethey will be struck by the air bag when itinflates in a crash. If this happens, seriousor fatal injury will result.

Failure to follow these instructions can resultin severe injuries to you or other occupants.If you sell your vehicle, it is important that youmake the buyer aware of this safetyinformation. Be sure to give the buyer thisOperator’s Manual.

G Warning!Accident research shows that the safest placefor children in an automobile is in a rear seat.

There is a possibility for a side impact air bag-related injury if occupants, especiallychildren, are not properly seated or restrainedwhen next to a side impact air bag whichneeds to deploy rapidly in a side impact inorder to do its job.To help avoid the possibility of injury, pleasefollow these guidelines:

(1) Always sit as upright as possible,wear the seat belt properly, and forchildren 12 years old and under,use an appropriately sized infantrestraint, toddler restraint, orbooster seat recommended for thesize and weight of the child.

(2) Always wear seat belts properly.

Air bags are designed to deploy only in certainRfrontal impacts (front air bags and driver’s

side knee bag)Rside impacts (side impact and window

curtain air bags) if the system determinesthe need for air bag deploymentRrollovers (window curtain air bags)Only in the event of such a situation will theyprovide their supplemental protection.The driver and passengers should alwayswear their seat belts. Otherwise it is notpossible for the air bags to provide theirsupplemental protection.In case of other types of impacts and impactsbelow air bag deployment thresholds, airbags will not deploy. The driver andpassengers will then be protected to theextent possible by a properly fastened seatbelt. A properly fastened seat belt is alsoneeded to provide the best possibleprotection in a rollover.Air bags are not a substitute for seat belts.Always wear your seat belt, regardless ofwhether or not your vehicle is equipped withair bags.It is important to your safety and that of yourpassengers to have deployed air bags

replaced and to have any malfunctioning airbags repaired. This will help to make sure theair bags will continue to provide supplementalcrash protection for occupants.

Safety guidelines for the seat belt, Emergency Tensioning Device (ETD) and air bag

G Warning!RDamaged seat belts or seat belts that have

been subjected to stress in an accidentmust be replaced. Their anchoring pointsmust also be checked. Only use seat beltsinstalled or supplied by an authorizedMercedes-Benz Center.RAir bags and pyrotechnic Emergency

Tensioning Devices (ETDs) containperchlorate material, which may requirespecial handling and regard for theenvironment. Check with your localgovernment’s disposal guidelines.California residents, seewww.dtsc.ca.gov/HazardousWaste/Perchlorate/index.cfm.RAir bags and ETDs are designed to function

on a one-time-only basis. An air bag or ETDthat has deployed must be replaced. PRE-SAFE® has electrically operated reversiblepre-tensioners in addition to thepyrotechnic ETDs.RDo not pass seat belts over sharp edges.

They could tear.RDo not make any modification that could

change the effectiveness of the seat belts.RDo not bleach or dye seat belts as this may

severely weaken them. In a crash they maynot be able to provide adequate protection.RNo modifications of any kind may be made

to any components or wiring of the SRS.RDo no change or remove any component or

part of the SRS.RDo not install additional trim material, seat

covers, badges, etc. over the steering

wheel hub, front passenger front air bagcover, outboard sides of the seatbackrests, door trim panels, or door frametrims.RDo not install additional electrical/

electronic equipment on or near SRScomponents and wiring.RKeep area between air bags and occupants

free of objects (e.g. packages, purses,umbrellas, etc.).RDo not hang items such as coat hangers

from the coat hooks or handles over thedoor. These items may be thrown around inthe vehicle and cause head and otherinjuries when the window curtain air bag isdeployed.RAir bag system components will be hot after

an air bag has inflated. Do not touch them.RNever place your feet on the instrument

panel, dashboard, or on the seat. Alwayskeep both feet on the floor in front of theseat.RImproper repair work on the SRS creates a

risk of rendering the SRS inoperative orcausing unintended air bag deployment.Work on the SRS must therefore only beperformed by qualified technicians.Contact an authorized Mercedes-BenzCenter.RFor your protection and the protection of

others, when scrapping the air bag unit orETD, our safety instructions must befollowed. These instructions are availablefrom any authorized Mercedes-BenzCenter.RGiven the considerable deployment speed,

required inflation volume, and the materialof the air bags, there is the possibility ofabrasions or other, potentially more seriousinjuries resulting from air bag deployment.

If you sell your vehicle, we stronglyrecommend that you inform the subsequentowner that the vehicle is equipped with SRS.

Front air bags

G Observe Safety notes, see page 37.

Driver’s front air bag : and front passengerfront air bag ; are designed to provideincreased protection for the driver and frontpassenger against the risk of injuries to thehead and thorax.Driver and front passenger front air bag anddriver’s side knee bag are deployedRin the event of certain frontal impactsRif the system determines that air bag

deployment can offer additional protectionto that provided by the seat beltRdepending on whether the respective seat

belt is in useRindependently of the side impact air bags

and/or the window curtain air bagsThe front air bags in this vehicle have beendesigned to inflate in two stages. This allowsthe air bags to have different rates of inflation.The rate of inflation is based on the vehicledeceleration rate as assessed by the air bagcontrol unit.Vehicles with OCS, USA only: The frontpassenger front air bag deployment isadditionally influenced by the passenger’sweight category as identified by the OccupantClassification System (OCS) (Y page 42).Vehicles with OCS, USA only: The lighter thefront passenger-side occupant, the higher the

vehicle deceleration rate required for secondstage inflation of the front passenger front airbag.The air bags will not deploy in impacts whichdo not exceed the system’s presetdeployment thresholds. You will then beprotected by the fastened seat belts.The front air bags will not deploy in the eventof a rollover unless the vehicle’s rate oflongitudinal deceleration or accelerationexceeds the preset deployment threshold forthe front air bags.The front passenger front air bag will only bedeployed ifRvehicles with OCS, USA only: the system,

based on OCS weight sensor readings,detects that the front passenger seat isoccupiedRthe 42 indicator lamp in the

center console is not lit(USA only: (Y page 42),Canada only: (Y page 46))Rthe impact exceeds a preset deployment

threshold

! Vehicles with BabySmart™ air bagdeactivation system (Canada only): Do notplace objects heavier than 20 lb (9 kg) onthe front passenger seat. This could causethe front or side impact air bag on the frontpassenger side to deploy in a crash whichexceeds the system’s deploymentthreshold.

Side impact air bags

G Observe Safety notes, see page 37.

G Warning!The pressure sensors for side impact air bagcontrol are located in the doors. Do notmodify any components of the doors or doortrim panels including, for example, theaddition of door speakers.Improper repair work on the doors or themodification or addition of components to thedoors create a risk of rendering the sideimpact air bags inoperative or causingunintended air bag deployment. Work on thedoors must therefore only be performed byqualified technicians. Contact an authorizedMercedes-Benz Center.

Front side impact air bags : and rear sideimpact air bags ; are designed to provideincreased protection for the thorax but notthe head, neck and arms.The side impact air bags are deployedRon the impacted side of the vehicleRin instances with a high rate of lateral

vehicle deceleration or accelerationRregardless of whether the seat belts on the

impacted side of the vehicle are in useRindependently of the front air bagsRindependently of the ETDs

Vehicles with OCS (USA only): The frontpassenger side impact air bag will not deployif the OCS senses that the front passengerseat is empty and the front passenger seatbelt is not fastened. With the front passengerseat empty and the seat belt fastened, thefront passenger side impact air bag willdeploy independently of the empty seat.Whether a seat belt is recognized as fasteneddepends on whether or not the latch plate isproperly inserted into the buckle.The side impact air bags are not deployed inside impacts which do not exceed thesystem’s deployment threshold.The side impact air bags will not deploy in theevent of a rollover unless the vehicle’s rate oflateral deceleration or acceleration exceedsthe preset deployment threshold for the sideimpact air bags.

! Vehicles with BabySmart™ air bagdeactivation system (Canada only): Do notplace objects heavier than 20 lb (9 kg) onthe front passenger seat. This could causethe front or side impact air bag on the frontpassenger side to deploy in a crash whichexceeds the system’s deploymentthreshold.

G Warning!Only use seat covers which have been testedand approved by Mercedes-Benz for yourvehicle model. Using other seat covers mayinterfere with or prevent the deployment ofthe side impact air bags. Contact anauthorized Mercedes-Benz Center foravailability.

Window curtain air bags : are not deployedin impacts which do not exceed the system’sdeployment threshold.Window curtain air bags : deploy in the areaindicated by the arrows.

Occupant Classification SystemThe Occupant Classification System (OCS) isstandard equipment in USA.The OCS activates or deactivates the frontpassenger front air bag automatically. Therespective status is based on the classifiedoccupant weight category determined by

weight sensor readings from the frontpassenger seat.The system does not deactivateRthe front passenger side impact air bagRthe window curtain air bagRthe Emergency Tensioning Devices (ETDs)To be classified correctly, the front passengermust sitRwith the seat belt properly fastenedRin a position that is as upright as possible

with the back against the seat backrestRwith the feet on the floorIf the occupant’s weight is transferred toanother object in the vehicle (e.g. by leaningon armrests), the OCS may not be able toproperly approximate the occupant’s weightcategory.Furthermore, the occupant weight mayappear to increase or decrease due to thefollowing:Robjects hanging on the seatRobjects lodged underneath the seatRobjects stuffed between the seat and

middle consoleRobjects stuffed between the seat and doorRother passengers pushing on the seatRobjects applying pressure to the back of

the seatAlways make sure the seat has clearancein all directions at all times.

If your seat, including the trim cover andcushion, needs to be serviced in any way, takethe vehicle to an authorized Mercedes-BenzCenter.Only seat accessories approved byMercedes-Benz may be used.Both the driver and the front passengershould always use the 42indicator lamp as an indication of whether ornot the front passenger is properlypositioned.

The infant or child restraint must be properlysecured with the vehicle’s seat belt, the seatbelt and top tether strap, or lower anchors andtop tether strap, fully in accordance with thechild seat manufacturer’s instructions.Occupants, especially children, should alwayssit as upright as possible, wear the seat beltproperly and use an appropriately sized infantrestraint, toddler restraint, or booster seatrecommended for the size and weight of thechild.Children can be killed or seriously injured byan inflating air bag. Note the followingimportant information when circumstancesrequire you to place a child in the frontpassenger seat:RYour vehicle is equipped with air bag

technology designed to deactivate the frontpassenger front air bag in your vehiclewhen the system senses the weight of atypical 12-month-old child or less alongwith the weight of a standard appropriatechild restraint on the front passenger seat.RA child in a rear-facing child restraint on the

front passenger seat will be seriouslyinjured or even killed if the front passengerfront air bag inflates in a collision whichcould occur under some circumstances,even with the air bag technology installedin your vehicle. The only means tocompletely eliminate this risk is to neverplace a child in a rear-facing child restraintin the front seat. We therefore stronglyrecommend that you always place a childin a rear-facing child restraint in a backseat.RIf you must install a rear-facing child

restraint on the front passenger seatbecause circumstances require you to doso, make sure the 42indicator lamp is illuminated, indicatingthat the front passenger front air bag isdeactivated. Should the 42indicator lamp not illuminate or go out whilethe restraint is installed, please checkinstallation. Periodically check the

42 indicator lamp whiledriving to make sure the 42indicator lamp is illuminated. If the42 indicator lamp goes out orremains out, do not transport a child on thefront passenger seat until the system hasbeen repaired.A child in a rear-facing child restraint on thefront passenger seat will be seriouslyinjured or even killed if the front passengerfront air bag inflates.RIf you have to place a child in a forward-

facing child restraint on the front passengerseat, move the seat as far back as possible,use the proper child restraintrecommended for the age, size and weightof the child, and secure child restraint withthe vehicle’s seat belt according to the childseat manufacturer’s instructions. Forchildren larger than the typical 12-month-old child, the front passenger front air bagmay or may not be activated.

An incorrectlymounted child seat could cause injuries to thechild in case of an accident, instead ofprotecting the child.Follow the manufacturer’s instructions forinstallation of special child seats.

Seat belts

Safety notesThe use of seat belts and infant and childrestraint systems is required by law in all 50states, the District of Columbia, the U.S.territories and all Canadian provinces.Even where this is not the case, all vehicleoccupants should have their seat beltsfastened whenever the vehicle is in motion.For information on infants and childrentraveling with you in the vehicle and restraintsystems for infants and children, see“Children in the vehicle” (Y page 55).

G Warning!Always fasten your seat belt before driving off.Always make sure all of your passengers areproperly restrained. You and your passengersshould always wear seat belts.Failure to wear and properly fasten andposition your seat belt greatly increases yourrisk of injuries and their likely severity in anaccident.If you are ever in an accident, your injuries canbe considerably more severe without your

seat belt properly buckled. Without your seatbelt buckled, you are much more likely to hitthe interior of the vehicle or be ejected fromit. You can be seriously injured or killed.In the same crash, the possibility of injury ordeath is lessened if you are properly wearingyour seat belt. The air bags can only protectas intended if the occupants are properlywearing their seat belts.

G Warning!Never ride in a moving vehicle with the seatbackrest in an excessively reclined position asthis can be dangerous. You could slide underthe seat belt in a collision. If you slide underit, the seat belt would apply force at theabdomen or neck. That could cause seriousor even fatal injuries. The seat backrest andseat belt provide the best restraint when thewearer is in a position that is as upright aspossible and the seat belt is properlypositioned on the body.

G Warning!Never let more people ride in the vehicle thanthere are seat belts available. Make sureeveryone riding in the vehicle is correctlyrestrained with a separate seat belt. Neveruse a seat belt for more than one person at atime.

G Warning!Damaged seat belts or seat belts that havebeen subjected to stress in an accident mustbe replaced. Also, the seat belt anchoringpoints must be checked.Only use seat belts which have been approvedby Mercedes-Benz.Do not make any modifications to the seatbelts. This can lead to unintended activationof the ETDs or to their failure to activate whennecessary.Do not bleach or dye seat belts as this mayseverely weaken them. In a crash they maynot be able to provide adequate protection.

Proper use of seat belts

G Warning!USE SEAT BELTS PROPERLYRSeat belts can only protect when used

properly. Never wear seat belts in any otherway than as described in this section, asthat could result in serious injuries in caseof an accident.REach occupant should wear their seat belt

at all times, because seat belts help reducethe likelihood of and potential severity ofinjuries in accidents, including rollovers.The integrated restraint system includesSRS (driver front air bag, driver side kneebag, front passenger front air bag, sideimpact air bags, window curtain air bags fordoor windows), Emergency TensioningDevices (ETDs), seat belt force limiters, andfront seat knee bolsters.The system is designed to enhance theprotection offered to properly beltedoccupants in certain frontal (front air bags,driver side knee bag and ETDs) and side(side impact air bags, window curtain airbags, and ETDs) impacts which exceedpreset deployment thresholds and incertain rollovers (window curtain air bagsand ETDs).RNever wear the shoulder belt under your

arm, against your neck or off your shoulder.In a frontal crash, your body would movetoo far forward. That would increase thechance of head and neck injuries. The seatbelt would also apply too much force to theribs or abdomen, which could severelyinjure internal organs such as your liver orspleen.Adjust the seat belt so that the shouldersection is located as close as possible tothe middle of the shoulder. It should not

touch the neck. Never pass the shoulderportion of the seat belt under your arm. Forthis purpose, you can adjust the height ofthe seat belt outlet.RPosition the lap belt as low as possible on

your hips and not across the abdomen. Ifthe lap belt is positioned across yourabdomen, it could cause serious injuries ina crash.RNever wear seat belts over rigid or

breakable objects in or on your clothing,such as eyeglasses, pens, keys etc., asthese might cause injuries.RMake sure the seat belt is always fitted

snugly. Take special care of this whenwearing loose clothing.RNever use a seat belt for more than one

person at a time. Do not fasten a seat beltaround a person and another person orother objects at the same time.RSeat belts should not be worn twisted. In a

crash, you would not have the full width ofthe seat belt to distribute impact forces.The twisted seat belt against your bodycould cause injuries.RPregnant women should also always use a

lap/shoulder belt. The lap belt portionshould be positioned as low as possible onthe hips to avoid any possible pressure onthe abdomen.RPlace the seat backrest in a position that is

as upright as possible.RCheck your seat belt during travel to make

sure it is properly positioned.RNever place your feet on the instrument

panel, dashboard, or on the seat. Alwayskeep both feet on the floor in front of theseat.RWhen using a seat belt to secure infant

restraints, toddler restraints, or children inbooster seats, always follow the child seatmanufacturer’s instructions.

G Warning!Do not pass seat belts over sharp edges. Theycould tear.Do not allow the seat belt to get caught in thedoor or in the seat adjustment mechanism.This could damage the seat belt.Never attempt to make modifications to seatbelts. This could impair the effectiveness ofthe seat belts.

Fastening the seat belts

G Warning!According to accident statistics, children aresafer when properly restrained in the rearseating positions than in the front seatingposition. Thus, we strongly recommend thatchildren be placed in the rear seats wheneverpossible. Regardless of seating position,children 12 years old and under must beseated and properly secured in anappropriately sized infant restraint, toddlerrestraint, or booster seat recommended forthe size and weight of the child. For additionalinformation, see “Children in the vehicle”.A child’s risk of serious or fatal injuries issignificantly increased if the child restraintsare not properly secured in the vehicle and/or the child is not properly secured in the childrestraint.

G Warning!Vehicles with BabySmart™ air bagdeactivation system, Canada only: Children12 years old and under must never ride in thefront seat, except in a Mercedes-Benzauthorized BabySmart™ compatible childseat, which operates with the BabySmart™system installed in the vehicle to deactivatethe front passenger front air bag when it isinstalled properly. Otherwise they will bestruck by the air bag when it inflates in acrash. If this happens, serious or fatal injurywill result.

If you and/or your passenger release theseat belt during driving, the seat belttelltale 7 starts flashing and thewarning chime sounds as described before.If the driver’s or the front passenger’s seatbelt remains unfastened after 60 seconds,the warning chime stops sounding, the seatbelt telltale 7 stops flashing butcontinues to be illuminated.After a vehicle standstill, the warning chimeis reactivated and the seat belt telltale7 is flashing again if the vehicle speedonce exceeds 15 mph (25 km/h).

The seat belt telltale 7 will only go out ifboth the driver’s and the front passenger’sseat belt (with the front passenger seatoccupied) are fastened, or the vehicle isstanding still and a front door is opened.For more information, see “Practical hints”(Y page 317).

Emergency Tensioning Device (ETD), seat belt force limiterThe seat belts for the front seats and secondrow outer seats are equipped with ETDs andseat belt force limiters. The seat belts for thethird-row seats are equipped with ETDs.The ETDs are designed to activate in thefollowing cases:Rin frontal or rear-end impacts exceeding

the system’s preset deployment thresholdRin side impacts exceeding the system’s

preset deployment threshold on the farside of the impactRin certain vehicle rolloversRif the restraint systems are operational and

functioning correctly, see “SRS indicatorlamp” (Y page 36)

The ETDs for the front seats will only activateif the front seat belts are fastened (latch plateproperly inserted into buckle).The ETDs for the rear outer seats (second-rowseats) or rear seats (third-row seats) will

activate with or without the respective seatbelts fastened.In an impact, the ETDs remove slack from theseat belts in such a way that the seat belts fitmore snugly against the body. Seat belt forcelimiters, when activated, are employed tohelp reduce the peak force exerted by theseat belts on occupants during a crash.

i The ETDs do not correct an incorrect seatposition or incorrectly worn seat belts.The ETDs do not pull occupants backtoward the seat backrest.

G Warning!Pyrotechnic ETDs that were activated must bereplaced.For your safety, when disposing of thepyrotechnic ETDs always follow our safetyinstructions. These are available at anyauthorized Mercedes-Benz Center.The PRE-SAFE® system has electricallyoperated reversible pre-tensioners that donot require replacement after activation.

Preventive occupant safety (PRE-SAFE®)

G Warning!The PRE-SAFE® system is intended to reducethe effects of an accident on vehicleoccupants who are wearing their seat beltproperly. Despite your vehicle being equippedwith the PRE-SAFE® system, the possibility ofpersonal injuries occurring as a result of anaccident cannot be eliminated. Therefore,always drive carefully and adjust your drivingto the prevailing road, weather, and trafficconditions.

Brake Assist System (BAS) (Y page 63)activatedRcritical dynamic driving situations, e.g.

when the vehicle has been caused toundersteer or oversteer because it hasexceeded its physical limitations or in caseof evasive steering maneuvers at speedsabove approximately 85 mph (140 km/h)

PRE-SAFE® takes the following measureswhen it is activated:RThe front seat belts are pre-tensioned

automatically.RVehicles with front passenger seat memory

function: If the passenger seat is in anunfavorable position, the seat will beadjusted to a position that seeks to betterprotect the occupant.RIf the vehicle is in a critical dynamic driving

situation, the door windows close, exceptfor a minimal gap that remains open.RVehicles with power tilt/sliding sunroof: If

the vehicle is in a critical dynamic drivingsituation, the tilt/sliding sunroof alsocloses, except for a minimal gap thatremains open.

If the closing procedure of any of theseelements is blocked, it will stop and openslightly.Once the hazardous situation no longer existsand an accident has been avoided, the seatbelt pre-tensioning is deactivated. All of thePRE-SAFE® settings can be re-adjustedfollowing the critical driving event.If the seat belts do not release:X Adjust the seat backrest or seat slightly to

the rear until the seat belt tension isreduced.The locking mechanism releases.

NECK-PRO active front head restraints

The NECK-PRO active front head restraintsare intended to offer the driver and frontpassenger increased protection fromwhiplash-type injuries. In the event of a rear-end collision, the NECK-PRO active front headrestraints on the front seats are designed tomove forward in the direction of travel. Theythus provide the head with increased supportearlier on in the collision sequence. TheNECK-PRO active front head restraints willmove forward whether the seats are occupiedor not.

G Warning!Do not attach any objects (e.g. hangers) to thehead restraint posts. Otherwise, the NECK-PRO active front head restraints may not beable to function properly or offer the intendeddegree of protection they were designed forin the event of a rear-end collision.

G Warning!Only use seat or head restraint covers whichhave been tested and approved by Mercedes-Benz for your vehicle model.Using other seat or head restraint covers mayinterfere with or prevent the activation of theNECK-PRO active front head restraints and/or the deployment of the front side impact airbags.Contact an authorized Mercedes-Benz Centerfor availability.

achieved with winter tires, or snow chainsas required.

Safety notes

G Warning!The following factors increase the risk ofaccidents:RExcessive speed, especially in turnsRWet and slippery road surfacesRFollowing another vehicle too closely

The driving safety systems described in thissection cannot reduce these risks or preventthe natural laws of physics from acting on thevehicle. They cannot increase braking orsteering efficiency beyond that afforded bythe condition of the vehicle brakes and tiresor the traction afforded.Only a safe, attentive, and skillful driver canprevent accidents.The capabilities of a vehicle equipped with thedriving safety systems described in thissection must never be exploited in a recklessor dangerous manner which could jeopardizethe user’s safety or the safety of others.Always adjust your driving style to theprevailing road and weather conditions andkeep a safe distance to other road users andobjects on the street.If a driving system malfunctions, other drivingsafety systems may also switch off. Observeindicator and warning lamps that may comeon as well as messages in the multifunctiondisplay that may appear.

ABS

G Observe Safety notes, see page 62.

G Warning!Do not pump the brake pedal. Use firm, steadybrake pedal pressure instead. Pumping thebrake pedal defeats the purpose of the ABS

and significantly reduces brakingeffectiveness.

The Antilock Brake System (ABS) regulatesthe brake pressure so that the wheels do notlock during braking. This allows you tomaintain the ability to steer your vehicle.The ABS is functional above a speed ofapproximately 5 mph (8 km/h) independentof road surface conditions.On slippery road surfaces, the ABS willrespond even to light brake pressure.The ABS indicator lamp ! indicator lampin the instrument cluster comes on when youswitch on the ignition. It goes out when theengine is running.

BrakingAt the instant one of the wheels is about tolock up, a slight pulsation can be felt in thebrake pedal. The pulsation indicates that theABS is in the regulating mode.X Keep firm and steady pressure on the brake

pedal while you feel the pulsation.Continuous, steady brake pedal pressureyields the advantages provided by the ABS,namely braking power and the ability to steerthe vehicle.The pulsating brake pedal can be anindication of hazardous road conditions andfunctions as a reminder to take extra carewhile driving.

Emergency brake maneuverX Keep continuous full pressure on the brake

pedal.

G Warning!If the ABS malfunctions, other driving safetysystems such as the BAS or the ESP® are alsoswitched off. Observe indicator and warninglamps that may come on as well as messagesin the multifunction display that may appear.

If the ABS malfunctions, the wheels may lockduring hard braking, reducing steeringcapability and extending the braking distance.

Off-road ABSWith the off-road driving program switchedon, or with the transmission in LOW RANGEmode, the ABS designed for off-road drivingis activated automatically.When applying the brakes at speeds below18 mph (30 km/h), the front wheels arelocked cyclically to shorten the brakingdistance (dig-in effect). This will restrictsteering the vehicle.

BAS

G Observe Safety notes, see page 62.The Brake Assist System (BAS) operates inemergency situations. If you apply the brakesvery quickly, the BAS provides full brakeboost automatically, thereby potentiallyreducing the braking distance.X Apply continuous full braking pressure until

the emergency braking situation is over.The ABS will prevent the wheels fromlocking.

When you release the brake pedal, the brakesfunction again as normal. The BAS is thendeactivated.

G Warning!If the BAS malfunctions, the brake system stillfunctions, but without the additional brakeboost available that the BAS would normallyprovide in an emergency braking maneuver.Therefore, the braking distance may increase.

EBP

G Observe Safety notes, see page 62.The Electronic Brake Proportioning (EBP)enhances braking effectiveness by allowingthe rear brakes to supply a greater proportion

of the braking effort in straight-line brakingwithout a loss of vehicle stability.

G Warning!If the EBP malfunctions, the brake system willstill function with full brake boost. However,the rear wheels could lock up duringemergency braking situations, for example.You could lose control of the vehicle andcause an accident.Adapt your driving style to the changeddriving characteristics.

ESP®

G Observe Safety notes, see page 62.The Electronic Stability Program (ESP®) isoperational as soon as the engine is running.It monitors the vehicle’s traction (force ofadhesive friction between the tires and theroad surface) and handling.The ESP® recognizes that the vehicle deviatesfrom the direction of travel as intended by thedriver. By applying brakes to individualwheels and by limiting the engine output, theESP® works to stabilize the vehicle. TheESP® is especially useful while driving off andon wet or slippery road surfaces. The ESP®

also stabilizes the vehicle during braking andsteering maneuvers.The ESP® warning lamp d in theinstrument cluster comes on when you switchon the ignition. It goes out when the engineis running.The ESP® warning lamp d in theinstrument cluster flashes when the ESP® isengaged.

G Warning!Never switch off the ESP® when you see theESP® warning lamp d flashing in theinstrument cluster. In this case proceed asfollows:RWhen driving off, apply as little throttle as

possible.RWhile driving, ease up on the accelerator

pedal.RAdapt your speed and driving style to the

prevailing road conditions.

Failure to observe these guidelines couldcause the vehicle to skid. The ESP® cannotprevent accidents resulting from excessivespeed.

! Only conduct operational or performancetests on a two-axle dynamometer. If suchtests are necessary, contact an authorizedMercedes-Benz Center. You couldotherwise seriously damage the brakesystem or the transfer case which is notcovered by the Mercedes-Benz LimitedWarranty.

! Because the ESP® operatesautomatically, the engine and ignition mustbe shut off (SmartKey in starter switchposition 0 or 1 or KEYLESS-GO start/stopbutton in position 0 or 1) when the parkingbrake is being tested on a brake testdynamometer. Such testing should be nolonger than 10 seconds.Active braking action through the ESP®

may otherwise seriously damage the brakesystem which is not covered by theMercedes-Benz Limited Warranty.

! The ESP® will only function properly if youuse wheels of the recommended tire sizeas specified in the “Technical data” sectionof this Operator’s Manual.

i The Distronic system and cruise controlswitch off automatically when the ESP®

engages.

Electronic Traction System (4-ETS)

G Observe Safety notes, see page 62.The 4-ETS (four-wheel Electronic TractionSystem) is a component of the ESP®. The4-ETS improves the vehicle’s ability to utilizeavailable traction, especially under slipperyroad conditions by applying the brakes to aspinning wheel. In addition, more power istransferred to the wheel(s) with traction.When you switch off the ESP®, the 4-ETS isstill enabled.X If conditions require, switch on the off-road

driving program (Y page 158) or the LOWRANGE mode (Y page 119).

Off-road 4-ETSWith the off-road driving program switched on(Y page 158), or the transmission in LOWRANGE mode (Y page 120), the 4-ETSdesigned for off-road use is activatedautomatically.

Switching off the ESP®

G Warning!The ESP® should not be switched off duringnormal driving other than in thecircumstances described below. Disablingthe system will reduce vehicle stability indriving maneuvers.Do not switch off the ESP® when a sparewheel is mounted.

To improve the vehicle’s traction, switch offthe ESP®. This allows the drive wheels to spinand thus cut into surfaces for better grip, forexampleRwhen driving with snow chainsRin deep snowRin sand or gravel

i When the ESP® is switched off and one ormore drive wheels are spinning, the ESP®

warning lamp d in the instrumentcluster flashes. However, the ESP® willthen not stabilize the vehicle.

X With the engine running, press ESP®

switch : until the ESP® warning lampd in the instrument cluster comes on.The ESP® is switched off.

G Warning!When the ESP® warning lamp d isilluminated continuously, the ESP® isswitched off or is not operational due to amalfunction. Vehicle stability in standarddriving maneuvers is reduced.Adapt your speed and driving to the prevailingroad conditions and to the non-operatingstatus of the ESP®.

! Avoid spinning of a drive wheel for anextended period with the ESP® switchedoff. This may cause serious damage to thedrivetrain which is not covered by theMercedes-Benz Limited Warranty.

Switching on the ESP®

X Press ESP® switch : until the ESP®

warning lamp d in the instrumentcluster goes out.You are now again in normal driving modewith the ESP® switched on.

Off-road ESP® With the off-road driving program switched on(Y page 158), or with the transmission inLOW RANGE mode (Y page 120), the ESP®

designed for off-road use is activatedautomatically. At speeds below 27 mph(45 km/h), the ESP® assists in over–understeering, thus improving vehicletraction.

ESP® trailer stabilization If the trailer you are towing should begin tosway, the rig can only be stabilized byimmediately applying the brakes hard.Steering during this maneuver will not help tostabilize the rig.The ESP® will assist you in such situations.The ESP® recognizes when the trailer startsswaying and will apply the brakes to reducethe vehicle speed to a non-critical speed that

Safety notes

G Warning!Make sure absolutely no objects areobstructing the pedals’ range of movement.Keep the driver’s footwell clear of allobstacles. If there are any floormats orcarpets in the footwell, make sure the pedalsstill have sufficient clearance.During sudden driving or braking maneuversthe objects could get caught between thepedals. You could then no longer brake oraccelerate. This could lead to accidents andinjury.

G Warning!With the engine not running, there is no powerassistance for the brake and steeringsystems. In this case, it is important to keepin mind that a considerably higher degree ofeffort is necessary to brake and steer thevehicle. Adapt your driving accordingly.

Starting the engine

G Warning!Inhalation of exhaust gas is hazardous to yourhealth. All exhaust gas contains carbonmonoxide (CO), and inhaling it can causeunconsciousness and possible death.Do not run the engine in confined areas (suchas a garage) which are not properly ventilated.If you think that exhaust gas fumes areentering the vehicle while driving, have thecause determined and correctedimmediately. If you must drive under theseconditions, drive only with at least onewindow fully open at all times.

LOW RANGE mode The LOW RANGE mode is available onvehicles with enhanced off-road package.In the following situations you should switchto the LOW RANGE mode:Rduring off-road drivingRbefore driving through waterRwhen towing up or down on steep gradientsWith LOW RANGE selected, the engine’spower delivery and the shifting behavior ofthe automatic transmission are adjusted.Furthermore, the ABS, the ESP®, and the4-ETS functions especially adapted to off-road travel are activated.For more information on off-road driving, see“Off-road driving” (Y page 262).For information on driving safety systemsduring LOW RANGE mode, see “Driving safetysystems” (Y page 61).

Gear ranges There are two possible settings.

HIGH RANGE

Road position for all normaldriving situations.(LOW RANGE mode off)

LOW RANGE

Off-road position fortraveling on rough terrain.(LOW RANGE mode on)Also use the off-roadposition when driving on-road on steep gradients,especially when towing atrailer.LOW RANGE acts by raisingthe engine’s gear ratio. Thevehicle travels at roughlythird the speed compared towhen in HIGH RANGEposition, leading to anincrease in the engine’sdrive power.

G Warning!Always wait until the procedure of shiftingfrom HIGH RANGE to LOW RANGE – and fromLOW RANGE to HIGH RANGE – has beenentirely completed. During this procedure donot turn off the engine or shift the automatictransmission into another gear.If you do not wait until the shifting procedurehas been entirely completed then it might notbe correctly performed. The transfer casemight be in neutral, thus interrupting thetransfer of power between the engine and thedrive axle.The vehicle is then freely movable, even if agear has been selected, and couldunintentionally be set into motion –particularly on up – or downhill grades. Thiscould lead to an accident and cause injury toyourself and others.Please observe related messages appearingin the multifunction display.

and rear axle differential to improve vehicletraction.The center differential compensates fordifferences in wheel rotation between thefront and rear axle.The rear axle differential compensatesdifferences between the rear wheels.

i At the front axles, the 4-ETS systemcompensates for any traction problems.

For more information on off-road driving, see“Off-road driving” (Y page 262).

A few words about differentials and differential locks

When a vehicle negotiates a turn, wheels onthe outside of the curve must travel fartherand rotate faster than the inside wheels. Thedifferential, the operation of a set of gearsthat allows the powered wheels in a vehicleto turn at different speeds, makes thisessential function possible.The drawback is that the differential alsosends most of the engine’s power to thewheel with the least load or strain on it. Forexample, if one of a vehicle’s powered wheelssits on a patch of snow and spins becausethere is no traction, all of the engine’s powerwill go to that wheel because the power willtake the path of least resistance. Meanwhile,the opposite wheel, sitting on dry pavementwhere it could get enough grip to start thevehicle moving, sits idle because it receivesno power.The 4-ETS addresses this problem andprovides for good control and steering abilityby automatically slowing the slipping wheeland thus increasing the power to the othernon-slipping drive wheels to get the vehiclemoving. The ESP® and the 4-ETS in thisvehicle feature such intelligent limited-slipdifferential technology, ideally suited for on-road and light off-road driving. Transfer caseposition LOW (Y page 120) also enhances off-road driving capabilities.

More extreme off-road conditions may call foranother solution, engaging a differential lockor preventing the differential from operatingaltogether. This vehicle comes with twodifferential locks: transfer case (center) andrear. Each can be engaged simply byoperating the rotary switch located on thecenter console (Y page 123). When thetransfer case (center) differential is locked,the combined (or average) speed of the frontwheels is identical to the combined rearwheel speed. When the rear differential islocked, both rear wheels turn at the samespeed, independent of the individual torque.Please be aware that engaging the differentiallocks will significantly reduce the steeringability of the vehicle.For your safety and the safety of others andto prevent damage to the vehicle, thedifferential locks must not be engaged whendriving on paved roads. It is important tounderstand that during on-road/paveddriving, differentials are absolutely necessaryfor providing the essential control andsteering ability of the vehicle. The differentiallocks, therefore, must not be engaged whendriving on paved roads and should only beused to the extent necessary to negotiate off-road conditions which cannot be handled bythe systems (the 4-ETS, the ESP®, and thetransfer case in LOW RANGE mode) thisvehicle comes equipped with.

Switching differential locks ! If the differential locks are engaged,

accelerate gently when setting the vehiclein motion.Only operate the vehicle on a single axledynamometer if the axle not being driven isjacked up or the associated propeller shaftis disconnected.Otherwise the transmission could bedamaged.

You can select between three locking modes.

Rotary switch for differential locks: Rotatable outer adjustment ring with

indicator lamp 2 AUTO mode: center differential is

automatically locked3 Center differential is completely locked4 Center and rear axle differential are

completely locked

AUTO modeThe AUTO mode is adequate for most drivingsituations since the center differential islocked and released as required.

i At speeds up to 19 mph (30 km/h), it ispossible to manually lock the differentiallocks for driving on rough terrain.

X Start the engine.The center differential lock is in AUTOmode. The indicator lamp on adjustmentring : above symbol à is on.

A message indicating that the centerdifferential lock is in AUTO mode appears inthe multifunction display when the off-roadmenu is selected. For selecting the off-roadmenu, see the “Controls in detail” section(Y page 131).

Center and rear axle differential locks

G Warning!Never drive on a paved surface with the centerand rear axle differential locks manuallyengaged. Ability to steer the vehicle is greatlyreduced when the differential locks aremanually engaged, increasing the risk of anaccident.For safety reasons, the locks areautomatically released at a vehicle speedabove 31 mph (50 km/h). Nevertheless, youshould only manually lock the differential ifabsolutely necessary because engaged lockswill restrict the vehicle drivetrain whilecornering and cause the vehicle to chatter.This could cause you to lose control of thevehicle and cause an accident.

! The differential locks must not beengaged manually when towing the vehicleor spinning the wheels.

The differential locks should only be engagedmanually if traction is insufficient in AUTOmode.The differential locks can be engaged in thesequence 3, 4 (Y page 123) up to a speedof 19 mph (30 km/h).Engage differential locks:Rfor off-road drivingRfor driving through waterRwhen driving on deep snow and icy or

fouled surfacesX Start the engine.X To select the desired locking mode, rotate

Distronic

Safety notesWhen activated, the Distronic adaptive cruisecontrol increases the driving convenienceafforded by the cruise control while travelingon expressways and other major roadways.RIf the Distronic distance sensor detects a

slower moving vehicle directly ahead, yourvehicle speed will be reduced so that you

follow that vehicle at your preset followingdistance.RIf there is no vehicle directly ahead of you,

the Distronic will function in the same wayas standard cruise control (Y page 144).

G Warning!The Distronic requires familiarity with itsoperational characteristics. We stronglyrecommend that you review the followinginformation carefully before operating thesystem.

G Warning!When the Distronic is braking, the brake pedalis retracted (i.e. depressed automatically).The pedals’ range of motion must not beimpeded by any obstacles:RDo not place any objects in the footwell.RMake sure that the floormats and carpets

are securely in place.RDo not rest your foot underneath the brake

pedal, as it could otherwise be trapped.

You could otherwise cause an accident andinjure yourself and/or others.

G Warning!The Distronic is a convenience system. Itsspeed adjustment reduction capability isintended to make cruise control moreeffective and usable when traffic speeds vary.It is not however, intended to, nor does it,replace the need for extreme care.The responsibility for the vehicle’s speed,distance to the preceding vehicle and, mostimportantly, brake operation to ensure a safestopping distance, always remains with thedriver.The Distronic cannot take street and trafficconditions into account. Complex drivingsituations are not always fully recognized bythe Distronic. This could result in wrong ormissing distance warnings.

G Warning!The Distronic adaptive cruise control is not asubstitute for active driving involvement. Itdoes not react to pedestrians or on stationaryobjects, nor does it recognize or predict thelane curvature or the movement of precedingvehicles.The Distronic can only apply 20% of themaximum braking power of the vehicle.It is the driver’s responsibility at all times tobe attentive to the road, weather and trafficconditions. Additionally, the driver mustprovide the steering, braking and other drivinginputs necessary to remain in control of thevehicle.High-frequency sources such as toll stations,speed measuring systems etc. can cause theDistronic system to malfunction.

G Warning!The Distronic cannot take road and trafficconditions into account. Only use theDistronic if the road, weather and trafficconditions make it advisable to travel at aconstant speed.

G Warning!Use of the Distronic can be dangerous onslippery roads. Rapid changes in tire tractioncan result in wheel spin and loss of control.The Distronic does not function in adversesight and distance conditions. Do not use theDistronic during conditions of fog, heavy rain,snow or sleet.

G Warning!The Distronic cannot take weather conditionsinto account. Switch off the Distronic or donot switch it on if:Rroads are slippery or covered with snow or

ice. The wheels could lose traction whilebraking or accelerating, and the vehiclecould skid.Rthe Distronic system sensor cover is dirty

or visibility is diminished due to snow, rain

or fog, for example. The distance controlsystem functionality could be impaired.

Always pay attention to surrounding trafficconditions even while the Distronic isswitched on. Otherwise, you may not be ableto recognize dangerous situations until it istoo late. This could cause an accident in whichyou and/or others could be injured.

G Warning!The “Resume” function should only beoperated if the driver is fully aware of thepreviously set speed and wishes to resumethis particular preset speed.

G Warning!Close attention to road and traffic conditionsis imperative at all times, regardless ofwhether or not the Distronic is activated.Use of the Distronic can be dangerous onwinding roads or in heavy traffic becauseconditions do not allow safe driving at aconstant speed.The Distronic will not react to stationaryobjects in the roadway (e.g. a stopped vehiclein a traffic jam or a disabled vehicle). TheDistronic will also not respond to oncomingvehicles.Switch off the Distronic:Rwhen changing from the left to the right

lane if vehicles are moving more slowly inthe left laneRwhen entering a turn lane or highway off

rampRin complex driving situations, such as in

highway construction zones

In these situations, the Distronic will continueto maintain the set speed unless deactivated.The Distronic is designed and intended onlyto maintain a set speed and keep a setdistance from moving objects in front of it.

Immediately brake the vehicle to increaseyour distance to the preceding vehicle. Thewarning sound is intended as a final cautionin which you should intercede with your ownbraking inputs to avoid a potentiallydangerous situation. Do not wait for theoperation of the warning signal to intercedewith your own braking. This will result inpotentially dangerous emergency brakingwhich will not always result in an impact beingavoided.Tailgating increases the risk of an accident.

G Warning!The Distronic brakes your vehicle with amaximum deceleration of 6.5 ft/s2 (2 m/s2).This corresponds to approximately 20% of themaximum deceleration of your vehicle.You must also apply the brakes yourself toavoid a collision. The Distronic brakes thevehicle in an effort to restore the presetdistance or to maintain the set speed. Thebrake pedal is automatically applied as thishappens which results in the brake pedalmovingKeep driver’s foot area clear at all times,including the area under the brake pedal.Objects stored in this area may impair pedalmovement which could interfere with thebraking ability of the Distronic system.Do not place your foot under the brake pedal– your foot could become caught.

Depressing the accelerator pedal does notdeactivate the Distronic. After a briefacceleration (e.g. for passing), the Distronicwill resume the last set speed.

Setting the following distance in DistronicYou can set the specified following distancefor Distronic by varying the time settingbetween 1.0 and 2.0 seconds. Using this timesetting and the current speed of your vehicle,Distronic calculates and sets the requiredfollowing distance to the preceding vehicle.The set distance will be shown in themultifunction display.

G Warning!It is up to the driver to exercise discretion toselect the appropriate setting given roadconditions, traffic, driver’s preferred drivingstyle and applicable laws and drivingrecommendations for safe following distance.

X Increasing distance: Turn distancesetting switch : in direction of arrow =.Increasing the distance setting tellsDistronic to maintain a greater followingdistance to the preceding vehicle.

X Decreasing distance: Turn distancesetting switch : in direction of arrow ;.Decreasing the distance setting tellsDistronic to maintain a shorter followingdistance to the preceding vehicle.

Driving with DistronicThis section describes a number of drivingsituations where special precaution isrequired on the part of the driver. Be preparedto brake in such situations. Braking willdeactivate the Distronic system.

G Warning!The Distronic works to maintain the speedselected by the driver unless a movingobstacle proceeding directly ahead of it in thesame travel direction is detected (e.g.following another vehicle ahead of you at yourset distance).This means that:RYour vehicle can pass another vehicle after

you have changed lanes.RWhile in a sharp turn or if the preceding

vehicle is in a sharp turn, the Distroniccould lose sight of the preceding vehicle.Your vehicle could then accelerate to thepreviously selected speed.

The Distronic regulates only the distancebetween your vehicle and those directlyahead of it, but does not register stationaryobjects in the road, e.g.:Ra stopped vehicle in a traffic jamRa disabled vehicleRan oncoming vehicle

The driver must always be alert, observe alltraffic and intercede as required by means ofsteering or braking the vehicle.

G Warning!The Distronic should not be used in snowy oricy road conditions.

The most likely cause for a malfunctioningsystem is a dirty Distronic system sensorcover (located in the hood grille), especiallyat times of snow and ice or heavy rain.In such a case, the Distronic will switch off,and the message DISTRONIC Currently Unavailable – See Operator’s Manualappears in the multifunction display.For cleaning and care of the Distronic systemsensor cover, see (Y page 278).

The DSR is an aid for driving downhill. TheDSR regulates your vehicle’s speed whendriving downhill to the value set in the controlsystem (Y page 141). The steeper thedownhill gradient is, the greater the brakeapplication. On flat road surfaces, the DSRbrakes only slightly or not at all.

G Warning!The Downhill Speed Regulation (DSR) is aconvenience system designed to assist thedriver during vehicle operation. The systemmust be set to be appropriate for thetopographical and weather conditionsencountered which can change quickly. Thedriver is and must remain at all timesresponsible for the vehicle speed and for safebrake operation.Depending on the programmed speed, actualvehicle speed and gradient, switching on theDSR while driving can cause the vehicle toslow down rapidly and you may hear a soundwhich is caused by the activation of thevehicle’s brake system through the DSR.Sudden and unexpected deceleration canresult in loss of vehicle control, causing anaccident and/or serious personal injury toyou and others. Do not switch on the DSR ina circumstance where rapid decelerationcould result in a loss of vehicle control.

The DSR regulates the vehicle’s speed inautomatic transmission positions D, or R.

i In addition, make use of the engine’sbraking effect by shifting the automatictransmission into a lower gear.

You can drive slower or faster than the setspeed at any time by braking the vehicle ordepressing the accelerator pedal.

i Whenever the DSR is switched on, theDSR will use the programmed defaultspeed to regulate the vehicle’s speed. Thedefault speed programmed at the factory is4 mph (Canada: 6 km/h). The default speedcan be reprogrammed using the control

system (Y page 141). The next time theDSR is switched on, the DSR will use thenewly programmed default speed toregulate the vehicle’s speed.Once the DSR is switched on, you canadjust the set speed using the cruisecontrol lever (Y page 145). Keep in mindthat adjusting the set speed using thecruise control lever with the DSR switchedon will not change the programmed defaultspeed. If the DSR is switched off and thenswitched on again, the DSR will use theprogrammed default speed.Depending on the road surface and level ofdownhill grade, the DSR may not be able tomaintain the set speed. To maintain the setspeed, apply the brakes if necessary.

All-wheel drive (4MATIC)In vehicles with all-wheel drive (4MATIC),both axles are powered at all times when thevehicle is being operated. The 4MATICimproves traction in conjunction with theESP® (Y page 63) and the Electronic TractionSystem (4-ETS) (Y page 64).

G Warning!If a drive wheel is spinning due to insufficienttraction:RWhile driving off, apply as little throttle as

possible.RWhile driving, ease up on the accelerator

pedal.RAdapt your speed and driving style to the

prevailing road conditions.

Failure to observe these guidelines couldcause the vehicle to skid.The 4MATIC cannot prevent accidentsresulting from excessive speed.

! Do not tow with one axle raised. Doing socould damage the transfer case, which isnot covered by the Mercedes-Benz Limited

Warranty. All wheels must be on or off theground. Observe instructions for towing thevehicle with all wheels on the ground.

! Only conduct operational or performancetests on a two-axle dynamometer. If suchtests are necessary, contact an authorizedMercedes-Benz Center. You couldotherwise seriously damage the brakesystem and/or the transfer case which isnot covered by the Mercedes-Benz LimitedWarranty.

i In winter operation, the maximumeffectiveness of the 4MATIC is onlyachieved with winter tires (Y page 257) orsnow chains as required.

G Warning!The Parktronic is a supplemental system. It isnot intended to, nor does it replace, the needfor extreme care. The responsibility duringparking and other critical maneuvers alwaysremains with the driver.

G Warning!Make sure no persons or animals are in ornear the area in which you are parking/maneuvering. Otherwise, they could beinjured.

! Special attention must be paid to objectswith smooth surfaces or low silhouettes(e.g. trailer couplings, painted posts,elevated crossbars or road curbs). Suchobjects may not be detected by the systemand can damage the vehicle.During parking maneuvers, pay specialattention to objects located above or belowthe height of the sensors (e.g. street curbs,painted posts, or trailer hitches etc.). TheParktronic system will not detect suchobjects at close range and damage to yourvehicle or the object may result.

! Ultrasonic signals from outside sources(e.g. truck air brakes, car wash, orjackhammers) may impair the operation ofthe Parktronic system.

Notes on 3-zone automatic climate control

With the help of a sun sensor, the automaticclimate control determines the relation of thesun to the vehicle and automatically adjuststhe inside temperature for every individualzone.The automatic climate control is operationalwhenever the engine is running. It cools thevehicle’s interior according to the angle andintensity of the sun’s rays, the outsidetemperature and the selected temperature.You can operate the automatic climatecontrol in either the automatic or manualmode.Nearly all dust particles, pollutants and odorsare filtered out before outside air enters thepassenger compartment through the airdistribution system.

G Warning!Severe conditions (e.g. strong air pollution)may require replacement of the filter beforeits scheduled replacement interval. A cloggedfilter will reduce the air volume to the interiorand the windows could fog up, impairingvisibility and endangering you and others.Have a clogged filter replaced as soon aspossible at an authorized Mercedes-BenzCenter.

The air conditioning will not engage (nocooling) if the A/C mode is deactivated(Y page 186).

G Warning!Follow the recommended settings for heatingand cooling given on the following pages.Otherwise the windows could fog up,impairing visibility and endangering you andothers.

Keep the air intake grille in front of thewindshield free of snow and debris.

i If the vehicle interior is hot, ventilate theinterior before driving off, see “Summeropening feature” (Y page 107). The climatecontrol will then adjust the interiortemperature to the set value much faster.

Deactivating the climate control system

G Warning!When the climate control system is switchedoff, the outside air supply and circulation arealso switched off. Only choose this setting fora short time. Otherwise the windows could fogup, impairing visibility and endangering youand others.

Always use cargo tie-downrings, and if so equipped, always use the cargonet when transporting cargo.Never drive a vehicle with the tailgate open.Deadly carbon monoxide (CO) gases mayenter vehicle interior resulting inunconsciousness and death.

Load distribution

The Gross Vehicle Weight (GVW) is the weightof the vehicle including:RfuelRtoolsRspare wheelRinstalled accessoriesRpassengersRluggage/cargoIt must never exceed the load limit and theGross Vehicle Weight Rating (GVWR) for yourvehicle. The load limit and the GVWR arespecified on the placard located on thedriver’s door B-pillar (Y page 242).In addition, the load must be distributed sothat the weight on each axle never exceeds

the Gross Axle Weight Rating (GAWR) for thefront and rear axle. The GVWR and GAWR foryour vehicle are indicated on the certificationlabel located on the driver’s door B-pillar(Y page 242).For more information, see “Tire and LoadingInformation” (Y page 242).The handling characteristics of a fully loadedvehicle depend greatly on the loaddistribution. It is therefore recommended toload the vehicle according to the illustrationshown. The heaviest items are to be placedtowards the front of the vehicle.

i The cargo compartment is the preferredplace to carry objects. The expanded cargovolume (Y page 201) should only be usedfor items which do not fit in the cargocompartment alone.

Please pay attention to and comply with thefollowing instructions when loading thevehicle and transporting cargo:RAlways place items being carried against

Programming tipsIf you are having difficulty programming theintegrated remote control, here are somehelpful tips:RCheck the frequency of hand-held remote

control A (typically located on the reverseside of the remote). The integrated remotecontrol is compatible with radio-frequencydevices operating between 280-390 MHz.RPut a new battery in hand-held remote

control A. This will increase the likelihoodof the hand-held remote control sending astronger and more accurate signal to theintegrated remote control.RWhile performing step 3, hold hand-held

remote control A at different lengths andangles from the signal transmitter button(;, = or ?) you are programming.Attempt varying angles at the distance of 2to 12 inches (5 to 30 cm) away or the sameangle at varying distances.RIf another hand-held remote control is

available for the same device, try theprogramming steps again using that otherhand-held remote control. Make sure newbatteries are in the hand-held remotecontrol before beginning the procedure.RStraighten the antenna wire from the

garage door opener assembly. This mayhelp improve transmitting and/or receivingsignals.

i Certain types of garage door openers areincompatible with the integrated remotecontrol. If you should experience furtherdifficulties with programming theintegrated remote control, contact anauthorized Mercedes-Benz Center, or callthe Mercedes-Benz Customer AssistanceCenter (USA only) at1-800-FOR-MERCedes (1-800-367-6372),or the HomeLink® Hotline (USA only) at1-800-355-3515, or the Customer Service(Canada only) at 1-800-387-0100.

Tires and wheels

Safety notesContact an authorized Mercedes-Benz Centerfor information on tested and recommendedrims and tires for summer and winteroperation. They can also offer adviceconcerning tire service and purchase.

G Warning!Replace rims or tires with the samedesignation, manufacturer and type as shownon the original part. For further information

contact an authorized Mercedes-Benz Center.If incorrectly sized rims and tires aremounted, the wheel brakes or suspensioncomponents can be damaged. Also, theoperating clearance of the wheels and thetires may no longer be correct.

G Warning!Worn, old tires can cause accidents. If the tiretread is worn to minimum tread depth, or ifthe tires have sustained damage, replacethem.When replacing rims, only use genuineMercedes-Benz wheel bolts specified for theparticular rim type. Failure to do so can resultin the bolts loosening and possibly anaccident.Retreaded tires are not tested orrecommended by Mercedes-Benz, sinceprevious damage cannot always berecognized on retreads. The operating safetyof the vehicle cannot be assured when suchtires are used.

G Warning!If you feel a sudden significant vibration orride disturbance, or you suspect that possibledamage to your vehicle has occurred, youshould turn on the hazard warning flashers,carefully slow down, and drive with caution toan area which is a safe distance from the road.Inspect the tires and the vehicle underbodyfor possible damage. If the vehicle or tiresappear unsafe, have the vehicle towed to thenearest authorized Mercedes-Benz Center ortire dealer for repairs.

G Warning!Do not drive with a flat tire. A flat tire affectsthe ability to steer or brake the vehicle. Youcould lose control of the vehicle. Continueddriving with a flat tire or driving at high speedwith a flat tire will cause excessive heat build-up and possibly a fire.

Important guidelinesROnly use sets of tires and rims of the same

type and make.RTires must be of the correct size for the rim.RBreak in new tires for approximately

60 miles (100 km) at moderate speeds.RRegularly check the tires and rims for

damage. Dented or bent rims can cause tireinflation pressure loss and damage to thetire beads.RIf the vehicle is heavily loaded, check tire

inflation pressure and correct as required.RDo not allow your tires to wear down too

far. Adhesion properties on wet roads aresharply reduced at tread depths of lessthan 1/8 in (3 mm).RWhen replacing individual tires, you should

mount new tires on the front wheels first(on vehicles with same-sized wheels allaround).

Recommended tire inflation pressure

G Warning!Follow recommended tire inflation pressures.Do not underinflate tires. Underinflated tireswear excessively and/or unevenly, adverselyaffect handling and fuel economy, and aremore likely to fail from being overheated.Do not overinflate tires. Overinflated tires canadversely affect handling and ride comfort,wear unevenly, increase stopping distance,and result in sudden deflation (blowout)because they are more likely to becomepunctured or damaged by road debris,potholes etc.Do not overload the tires by exceeding thespecified load limit as indicated on the Tireand Loading Information placard on thedriver’s door B-pillar. Overloading the tirescan overheat them, possibly causing ablowout. Overloading the tires can also result

in handling or steering problems, or brakefailure.

Your vehicle is equipped with the Tire andLoading Information placard located on thedriver’s door B-pillar (Y page 242).The tire inflation pressure should be checkedregularly. Only adjust the tire inflationpressure on cold tires. The tires can beconsidered cold if the vehicle has beenparked for at least 3 hours or driven less than1 mile (1.6 km). Depending on the ambienttemperature, the driving speed and the tireload, the tire temperature changes. When thetire temperature changes by 18‡ (10†), thetire inflation pressure will change byapproximately 1.5 psi (0.1 bar). Keep this inmind when checking tire inflation pressure onwarm tires and adjust the tire pressure onlyif the tire inflation pressure is too low for thecurrent operating conditions. If you check thetire inflation pressure when the tires arewarm, the reading will be higher than the coldreading. This is normal. Do not let air out tomatch the specified cold tire inflationpressure. Otherwise, the tire will beunderinflated.Follow recommended cold tire inflationpressures listed on Tire and LoadingInformation placard on the driver’s doorB-pillar.Keeping the tires properly inflated providesthe best handling, tread life and ridingcomfort.In addition to the Tire and LoadingInformation placard on the driver’s doorB-pillar, also consult the tire inflationpressure label on the inside of the filler flapfor any additional information pertaining tospecial driving situations.

Check the tire inflation pressure at least oncea month.Check and adjust the tire inflation pressurewhen the tires are cold (Y page 234).

Checking tire inflation pressure manuallyFollow the steps below to achieve correct tireinflation pressure:X Remove the cap from the valve on one tire.X Firmly press a tire gauge onto the valve.X Read the tire inflation pressure on the tire

gauge and check against therecommended tire inflation pressure on theTire and Loading Information placard on thedriver’s door B-pillar (Y page 242). Ifnecessary, add air to achieve therecommended tire inflation pressure.

X If you have overfilled the tire, release tireinflation pressure by pushing the metal

stem of the valve with e.g. a tip of a pen.Then recheck the tire inflation pressurewith the tire gauge.

X Install the valve cap.X Repeat this procedure for each tire.

Tire pressure loss warning system (Canada only)While the vehicle is being driven, the tirepressure loss warning system monitors theset tire inflation pressures by evaluating eachwheel’s rotational speed. This allows thesystem to detect a significant loss of pressurein a tire. If a wheel’s rotational speed changesdue to falling tire inflation pressure, you willsee a corresponding warning message in themultifunction display.The tire pressure loss warning system mayfunction in a restricted manner or with a delayRwhen snow chains are mounted to the

vehicleRin the presence of ice and snowRwhen you are driving on a loose surface

(e.g. sand or gravel)Rwhen you are driving in a very sporty

manner (involving rapid acceleration orhigh speeds in curves)

G Warning!When the multifunction display shows themessage Tire Pressure Check Tires, oneor more of your tires are significantlyunderinflated. You should stop and checkyour tires as soon as possible, and inflatethem to the proper tire inflation pressure asindicated on the vehicle’s Tire and LoadingInformation placard or on the tire inflationpressure label.Driving on a significantly underinflated tirecauses the tire to overheat and can lead totire failure. Underinflation also reduces fuelefficiency and tire tread life, and may affectthe vehicle’s handling and stopping ability.

Advanced Tire Pressure Monitoring System (Advanced TPMS), (USA only)Your vehicle is equipped with the AdvancedTire Pressure Monitoring System (AdvancedTPMS). It measures the tire inflation pressurein the vehicle’s tires and issues warnings incase of pressure loss in one or more of thetires.The TPMS is equipped with a combination lowtire pressure/ TPMS malfunction telltale inthe instrument cluster. Depending on how thetelltale illuminates, it indicates a low tirepressure condition or a malfunction in theTPMS system itself:RIf the telltale illuminates continuously, one

or more of your tires is significantlyunderinflated. There is no malfunction inthe TPMS.RIf the telltale flashes for 60 seconds and

then stays illuminated, the TPMS systemitself is not operating properly.

The TPMS only functions on wheels that areequipped with the proper electronic sensors.

G Warning!The TPMS does not indicate a warning forwrongly selected inflation pressures. Alwaysadjust tire inflation pressure according to theTire and Loading Information placard or thesupplemental tire inflation pressureinformation on the inside of the fuel filler flap.The TPMS is not able to issue a warning dueto a sudden dramatic loss of pressure (e.g. tireblowout caused by a foreign object). In thiscase bring the vehicle to a halt by carefullyapplying the brakes and avoiding abruptsteering maneuvers.

G Warning!Each tire, including the spare (if provided),should be checked at least once a monthwhen cold and inflated to the inflationpressure recommended by the vehiclemanufacturer on the Tire and LoadingInformation placard on the driver’s door B-pillar or the tire inflation pressure label on theinside of the fuel filler flap. If your vehicle hastires of a different size than the size indicatedon the Tire and Loading Information placardor the tire inflation pressure label, you shoulddetermine the proper tire inflation pressurefor those tires.As an added safety feature, your vehicle hasbeen equipped with a tire pressure monitoringsystem (TPMS) that illuminates a low tirepressure telltale when one or more of yourtires are significantly underinflated.Accordingly, when the low tire pressuretelltale illuminates, you should stop and checkyour tires as soon as possible, and inflatethem to the proper pressure. Driving on asignificantly underinflated tire causes the tireto overheat and can lead to tire failure.Underinflation also reduces fuel efficiencyand tire tread life, and may affect the vehicle’shandling and stopping ability. Please note thatthe TPMS is not a substitute for proper tiremaintenance, and it is the driver’sresponsibility to maintain correct tirepressure, even if underinflation has notreached the level to trigger illumination of theTPMS low tire pressure telltale.Your vehicle has also been equipped with aTPMS malfunction indicator to indicate whenthe system is not operating properly. TheTPMS malfunction indicator is combined withthe low tire pressure telltale. When thesystem detects a malfunction, the telltale willflash for approximately 1 minute and thenremain continuously illuminated. Thissequence will continue upon subsequentvehicle start-ups as long as the malfunctionexists. When the malfunction indicator is

The Tire and Loading Information placardshowing load limit information : is locatedon the driver’s door B-pillar (Y page 242).X Locate the statement “The combined

weight of occupants and cargo shouldnever exceed XXX kilograms or XXX lbs.”on the Tire and Loading Informationplacard.

The combined weight of all occupants,cargo/luggage and trailer tongue load (if

applicable) should never exceed the weightreferenced in that statement.

Seating capacity i Data shown on Tire and Loading

Information placard example are forillustration purposes only. Seating capacitydata are specific to each vehicle and mayvary from data shown in the followingillustration. Refer to Tire and LoadingInformation placard on vehicle for actualdata specific to your vehicle.

The seating capacity gives you importantinformation on the number of occupants thatcan be in the vehicle. Observe front and rearseating capacity. The Tire and LoadingInformation placard showing seatingcapacity : is located on the driver’s doorB-pillar (Y page 242).

Steps for determining correct load limit The following steps have been developed asrequired of all manufacturers under Title 49,Code of U.S. Federal Regulations, Part 575pursuant to the “National Traffic and MotorVehicle Safety Act of 1966”.X Step 1: Locate the statement “The

combined weight of occupants and cargoshould never exceed XXX kg or XXX lbs.”on your vehicle’s Tire and LoadingInformation placard.

X Step 3: Subtract the combined weight ofthe driver and passengers fromXXX kilograms or XXX lbs.

X Step 4: The resulting figure equals theavailable amount of cargo and luggage loadcapacity. For example, if the “XXX” amountequals 1 400 lbs and there will be five150 lbs passengers in your vehicle, theamount of available cargo and luggage loadcapacity is 650 lbs(1 400 - 750 (5 x 150) = 650 lbs).

X Step 5: Determine the combined weight ofluggage and cargo being loaded on thevehicle. That weight may not safely exceedthe available cargo and luggage loadcapacity calculated in step 4.

X Step 6 (if applicable): If your vehicle willbe towing a trailer, load from your trailerwill be transferred to your vehicle. Consultthis manual to determine how this reducesthe available cargo and luggage loadcapacity of your vehicle (Y page 246).

The following table shows examples on howto calculate total and cargo load capacitieswith varying seating configurations andnumber and size of occupants. The followingexamples use a load limit of 1 500 lbs. This is for illustration purposes only.

You may only use the MOExtended system inconjunction with the tire pressure losswarning system (Y page 237) or theAdvanced TPMS (Y page 239).

i Vehicles with MOExtended system arenot factory-equipped with a TIREFIT kit.When retrofitting with tires that do not haverun-flat characteristics, e.g. winter tires,you should also equip your vehicle with aTIREFIT kit. TIREFIT kits are available at anyauthorized Mercedes-Benz Center.

For information on driving in case of pressureloss in one or more tires (emergency mode),see the “Practical hints” section(Y page 345).

Tire care and maintenance

G Warning!Regularly check the tires for damage.Damaged tires can cause tire inflationpressure loss. As a result, you could losecontrol of your vehicle.Worn, old tires can cause accidents. If the tiretread is worn to minimum tread depth, or ifthe tires have sustained damage, replacethem.

Check the tire inflation pressure at least oncea month. For more information on checkingtire inflation pressure, see “Recommendedtire inflation pressure” (Y page 234).

Tire inspection Every time you check the tire inflationpressure, you should also inspect your tiresfor the following:Rexcessive treadwear (Y page 247)Rcord or fabric showing through the tire’s

rubberRbumps, bulges, cuts, cracks or splits in the

tread or side of the tireReplace the tire if you find any of the aboveconditions.

Make sure you also inspect the spare tireperiodically for condition and inflation. Sparetires will age and become worn over time evenif never used, and thus should be inspectedand replaced when necessary.

Life of tire

G Warning!Tires and spare tire should be replaced after6 years, regardless of the remaining tread.

The service life of a tire is dependent uponvarying factors including but not limited to:RDriving styleRTire inflation pressureRDistance driven

Tread depth

G Warning!Although the applicable federal motor vehiclesafety laws consider a tire to be worn whenthe treadwear indicators (TWI) become visibleat approximately 1/16 in (1.6 mm), werecommend that you do not allow your tiresto wear down to that level. As tread depthapproaches 1/8 in (3 mm), the adhesionproperties on a wet road are sharply reduced.Depending upon the weather and/or roadsurface (conditions), the tire traction varieswidely.

Do not allow your tires to wear down too far.Adhesion properties on wet roads are sharplyreduced at tread depths of less than 1/8 in(3 mm).Treadwear indicators (TWI) are required bylaw. These indicators are located in six placeson the tread circumference and becomevisible at a tread depth of approximately1/16 in (1.6 mm), at which point the tire isconsidered worn and should be replaced.The recommended minimum tire tread depthfor summer tires is 1/8 in (3 mm).

recommended minimum tire tread depth forwinter tires is 1/6 in (4 mm).

Treadwear indicator : appears as a solidband across the tread.

Storing tires ! Keep unmounted tires in a cool, dry place

with as little exposure to light as possible.Protect tires from contact with oil, greaseand fuels.

Cleaning tires ! Never use a round nozzle to power wash

tires. The intense jet of water can result indamage to the tire.Always replace a damaged tire.

Uniform Tire Quality Grading Standards

The Uniform Tire Quality Grading is a U.S.Government requirement designed to givedrivers consistent and reliable information

regarding tire performance. Tiremanufacturers are required to grade tiresbased on three performance factors:treadwear :, traction ;, and temperatureresistance =. Although not a Government ofCanada requirement, all tires made for sale inNorth America have these grades branded onthe sidewall.

i For illustration purposes only. Actual dataon tires are specific to each vehicle andmay vary from data shown in aboveillustration.

Quality grades can be found, whereapplicable, on the tire sidewall between treadshoulder and maximum section width. Forexample:

Treadwear Traction Temperature

200 AA A

All passenger car tires must conform tofederal safety requirements in addition tothese grades.

Treadwear The treadwear grade is a comparative ratingbased on the wear rate of the tire when testedunder controlled conditions on a specifiedU.S. Government test course. For example, atire graded 150 would wear one and one-half(1 1/2) times as well on the governmentcourse as a tire graded 100.The relative performance of tires dependsupon the actual conditions of their use,however, and may depart significantly fromthe norm due to variations in driving habits,service practices and differences in roadcharacteristics and climate.

Traction

G Warning!The traction grade assigned to this tire isbased on straight-ahead braking traction

tests, and does not include acceleration,cornering, hydroplaning, or peak tractioncharacteristics.

The traction grades, from highest to lowest,are AA, A, B, and C. Those grades representthe tire’s ability to stop on wet pavement asmeasured under controlled conditions onspecified government test surfaces of asphaltand concrete. A tire marked C may have poortraction performance.

G Warning!If ice has formed on the road, tire traction willbe substantially reduced. Under such weatherconditions, drive, steer and brake withextreme caution.

The safe speed on a wet, snow covered or icyroad is always lower than on a dry road.You should pay particular attention to thecondition of the road whenever the outsidetemperature is close to the freezing point.Mercedes-Benz recommends winter tires(Y page 257) with a minimum tread depth ofapproximately 1/6 in (4 mm) on all four wheelsfor the winter season to ensure normalbalanced handling characteristics. Onpacked snow, they can reduce your stoppingdistance compared to summer tires.Stopping distance, however, is stillconsiderably greater than when the road isnot covered with snow or ice. Exerciseappropriate caution.

! Avoid spinning of a drive wheel. This maycause serious damage to the drivetrainwhich is not covered by the Mercedes-BenzLimited Warranty.

Temperature

G Warning!The temperature grade for this tire isestablished for a tire that is properly inflatedand not overloaded. Excessive speed,underinflation, or excessive loading, eitherseparately or in combination, can cause

excessive heat build-up and possible tirefailure.

The temperature grades are A (the highest),B, and C, representing the tire’s resistance tothe generation of heat and its ability todissipate heat when tested under controlledconditions on a specified indoor laboratorytest wheel. Sustained high temperature cancause the material of the tire to degenerateand reduce tire life, and excessivetemperature can lead to sudden tire failure.The grade C corresponds to a level ofperformance which all passenger car tiresmust meet under the Federal Motor VehicleSafety Standard No. 109. Grades B and Arepresent higher levels of performance on thelaboratory test wheel than the minimumrequired by law.

Rotating tires

G Warning!Rotate front and rear wheels only if the tiresare of the same dimension.If your vehicle is equipped with mixed-sizetires (different tire dimensions front vs. rear),tire rotation is not possible.

G Warning!Have the tightening torque checked afterchanging a wheel. The wheels could comeloose if they are not tightened to a torque of110 lb-ft (150 Nm).Only use genuine Mercedes-Benz wheel boltsspecified for your vehicle’s rims.

Tire rotation can be performed on vehicleswith tires of the same dimension all around.If your vehicle is equipped with tires of thesame dimension all around, tires can berotated, observing a front-to-rear rotationpattern that will maintain the intendedrotation (spinning) direction of the tire(Y page 246).In some cases, such as when your vehicle isequipped with mixed-size tires (different tire

General: Depending on the design standardsused, the tire size molded into the sidewallmay have no letter or a letter preceding thetire size designation.No letter preceding the size designation (asillustrated above): Passenger car tire basedon European design standards.Letter “P” preceding the size designation:Passenger car tire based on U.S. designstandards.Letter “LT” preceding the size designation:Light Truck tire based on U.S. designstandards.Letter “T” preceding the size designation:Temporary spare tires which are highpressure compact spares designed fortemporary emergency use only.

Tire widthTire width : indicates the nominal tire widthin millimeters.

Aspect ratioAspect ratio ; is the dimensionalrelationship between tire section height andsection width and is expressed in percentage.The aspect ratio is arrived at by dividingsection height by section width.

Tire codeTire code = indicates the tire constructiontype. The “R” stands for radial tire type. Letter“D” means diagonal or bias ply construction;letter “B” means belted-bias ply construction.At the tire manufacturer’s option, any tirewith a speed capability above 149 mph(240 km/h) can include a “ZR” in the sizedesignation (for example: 245/40 ZR 18). Foradditional information, see “Tire speedrating” (Y page 252).

Rim diameterRim diameter ? is the diameter of the beadseat, not the diameter of the rim edge. Therim diameter is indicated in inches (in).

Load indexG Warning!The tire load rating must always be at leasthalf of the GAWR of your vehicle. Otherwise,tire failure may be the result which may causean accident and/or serious injury to you orothers.Always replace rims and tires with the samedesignation, manufacturer and type as shownon the original part.

G Warning!Do not overload the tires by exceeding thespecified load limit as indicated on the Tireand Loading Information placard on thedriver’s door B-pillar. Overloading the tirescan overheat them, possibly causing ablowout. Overloading the tires can also resultin handling or steering problems, or brakefailure.

Winter driving

General informationHave your vehicle winterized at an authorizedMercedes-Benz Center.

i Vehicles with diesel engine:Do not cover the radiator, for example witha winter front. Otherwise the readings ofthe on-board diagnostic system may beinaccurate. Some of theses readings arerequired by law and must be accurate at alltimes.

Winter tires

G Warning!Winter tires with a tread depth of less than1/6 in (4 mm) must be replaced. They are nolonger suitable for winter operation.

G Warning!If you use your spare wheel when winter tiresare fitted on the other wheels, be aware thatthe difference in tire characteristics may verywell impair turning stability and that overalldriving stability may be reduced. Adapt yourdriving style accordingly.Have the spare wheel replaced by a regularroad wheel with a winter tire at the nearestauthorized Mercedes-Benz Center.

Always use winter tires at temperaturesbelow 45‡ (7†) and whenever wintry roadconditions prevail. Not all M+S rated tiresprovide special winter performance. Makesure the tires you use show the mountain/snowflakeimarking on the tire sidewall.These tires meet specific snow tractionperformance requirements of the RubberManufacturers Association (RMA) and theRubber Association of Canada (RAC) andhave been designed specifically for use insnow conditions. Use of winter tires is theonly way to achieve the maximumeffectiveness of your vehicle’s driving safetysystems such as the ABS and the ESP® inwinter operation.For safe handling, make sure all mountedwinter tires are of the same make and havethe same tread design.For information on winter tires for yourvehicle model, see the “Technical data”section (Y page 365).Always observe the speed rating of the wintertires installed on your vehicle.

system (Y page 237) or the Advanced TirePressure Monitoring System (Y page 239).

Snow chains! Vehicles with Adaptive Damping System

(ADS):When driving with snow chains, do notselect SPORT mode as this may result indamage to your vehicle.

! Some tire sizes do not leave adequateclearance for snow chains. To help avoidserious damage to your vehicle or tires,make sure the use of snow chains ispermissible as specified in the “Technicaldata” section of this Operator’s Manual.

Snow chains should only be driven on snow-covered roads at speeds not to exceed30 mph (50 km/h). Remove chains as soonas possible when driving on roads withoutsnow.Observe the following guidelines when usingsnow chains:RUse of snow chains is not permissible with

all wheel/tire combinations (Y page 365).RUse snow chains in pairs and on rear

wheels only. Follow the manufacturer’smounting instructions.

! If snow chains are mounted to the frontwheels, they may scrape against the bodyor axle components. The tires or the vehiclecould be damaged as a result.ROnly use snow chains that are approved by

Mercedes-Benz. Any authorized Mercedes-Benz Center will be glad to advise you onthis subject.RUse of snow chains may be prohibited

depending on location. Always check local

and state laws before installing snowchains.RDo not use snow chains on the spare wheel.

i When driving with snow chains, you maywish to switch off the ESP® (Y page 63)before setting the vehicle in motion. Thiswill improve the vehicle’s traction.

Winter driving instructions

G Warning!If the vehicle becomes stuck in snow, makesure snow is kept clear of the exhaust pipeand from around the vehicle with the enginerunning. Otherwise, deadly carbon monoxide(CO) gases may enter vehicle interiorresulting in unconsciousness and death.To assure sufficient fresh air ventilation, opena window slightly on the side of the vehiclenot facing the wind.

G Warning!The outside temperature indicator is notdesigned to serve as an ice-warning deviceand is therefore unsuitable for that purpose.Indicated temperatures just above thefreezing point do not guarantee that the roadsurface is free of ice. The road may still be icy,especially in wooded areas or on bridges.

G Warning!On slippery road surfaces, never downshift inorder to obtain braking action. This couldresult in drive wheel slip and reduced vehiclecontrol. Your vehicle’s ABS will not preventthis type of control loss.Do not engage the transfer case in positionLOW when driving on ice or packed snow. Atspeeds below 18 mph (30 km/h) vehiclesteering is adversely affected by the Off-roadABS.

The most important rule for slippery or icyroads is to drive sensibly and to avoid abruptacceleration, braking and steering

maneuvers. Do not use the cruise controlsystem under such conditions.When the vehicle is in danger of skidding, shiftthe automatic transmission to neutralposition N. Try to keep the vehicle undercontrol by corrective steering action.

i For information on driving with snowchains, see “Snow chains” (Y page 258).

Road salts and chemicals can adverselyaffect braking efficiency. Increased pedalforce may become necessary to produce thenormal brake effect.Depressing the brake pedal periodically whentraveling at length on salt-strewn roads canbring road-salt-impaired braking efficiencyback to normal.If the vehicle is parked after being driven onsalt-treated roads, the braking efficiencyshould be tested as soon as possible afterdriving is resumed.

G Warning!Make sure not to endanger any other roadusers when carrying out these brakingmaneuvers.

Driving instructions

Drive sensibly – save fuelTo save fuel you should:RKeep tires at the recommended inflation

pressures.RRemove unnecessary loads.RRemove carriers when not in use.RRemove the crossbars when not in use.RAllow engine to warm up under low load

use.RAvoid frequent acceleration and

deceleration.RHave all maintenance work performed at

the intervals specified in the MaintenanceBooklet and as required by the

Maintenance system. Contact anauthorized Mercedes-Benz Center.

Fuel consumption is also increased by drivingin cold weather, in stop-and-go traffic, onshort trips and in mountainous areas.

Drinking and driving

G Warning!Drinking and driving and/or taking drugs anddriving are very dangerous combinations.Even a small amount of alcohol or drugs canaffect your reflexes, perceptions andjudgment.The possibility of a serious or even fatalaccident are greatly increased when you drinkor take drugs and drive.Do not drink or take drugs and drive or allowanyone to drive who has been drinking ortaking drugs.

Pedals

G Warning!Make sure absolutely no objects areobstructing the pedals’ range of movement.Keep the driver’s footwell clear of allobstacles. If there are any floormats orcarpets in the footwell, make sure that thepedals still have sufficient clearance.During sudden driving or braking maneuvers,the objects could get caught between thepedals. You could then no longer brake oraccelerate. This could lead to accidents andinjury.

Power assistance

G Warning!There is no power assistance for the steeringand the brake when the engine is not running.

Steering and braking requires significantlymore effort and you could lose control of thevehicle and cause an accident as a result.Do not turn off the engine while the vehicle isin motion.

Brakes

Downhill grades! When driving down long and steep

grades, relieve the load on the brakes byshifting into a lower gear to use theengine’s braking power. This helps preventoverheating of the brakes and reduceswear.When using the engine’s braking power, adrive wheel may not spin for an extendedperiod of time, e.g. on slippery roadsurfaces. This may cause serious damageto the drivetrain which is not covered by theMercedes-Benz Limited Warranty.

Continuous or hard braking

G Warning!Resting your foot on the brake pedal willcause excessive and premature wear of thebrake pads.It can also result in the brakes overheating,thereby significantly reducing theireffectiveness. It may not be possible to stopthe vehicle in sufficient time to avoid anaccident.

After hard braking, it is advisable to drive onfor some time, rather than immediately park,so that the air stream will cool down thebrakes faster.

Wet roads

G Warning!After driving in heavy rain for some timewithout applying the brakes or through waterdeep enough to wet brake components, the

first braking action may be somewhatreduced and increased pedal pressure may benecessary to obtain expected brake effect.Maintain a safe distance from vehicles infront.

To help prevent brake disk corrosion afterdriving on wet or salt-covered roads, it isadvisable to brake the vehicle withconsiderable force prior to parking. The heatgenerated serves to dry the brakes.

Salt-covered roads

G Warning!A layer of salt on the brake discs and the brakelinings may cause a delay in the brakingeffect, resulting in a significantly increasedbraking distance, which could lead to anaccident.To avoid this danger, you should:Roccasionally brake carefully when you are

driving on salt-covered roads, so that anylayer of salt that may have built up on thebrake discs and the brake linings isremoved without putting other road usersat riskRmaintain a greater distance to the vehicle

ahead and drive with particular careRcarefully apply the brakes at the end of a

trip and immediately after commencing anew trip, so that salt residues are removedfrom the brake disc

Brake service! The brake fluid level in the reservoir may

be too low if the brake warning lamp in theinstrument cluster comes on and anacoustic warning sounds although theparking brake is released. Observeadditional messages in the multifunctiondisplay that may appear.Brake pad wear or a leak in the system maybe the reason for low brake fluid in thereservoir.

Have the brake system inspectedimmediately. Contact an authorizedMercedes-Benz Center.

All checks and service work on the brakesystem should be carried out by qualifiedtechnicians only. Contact an authorizedMercedes-Benz Center.Only install brake pads and use brake fluidrecommended by Mercedes-Benz.

G Warning!If other than recommended brake pads areinstalled, or other than recommended brakefluid is used, the braking properties of thevehicle can be degraded to an extent that safebraking is substantially impaired. This couldresult in an accident.

! Only conduct operational or performancetests on a two-axle dynamometer. If suchtests are necessary, contact an authorizedMercedes-Benz Center. You couldotherwise seriously damage the brakesystem or the transfer case which is notcovered by the Mercedes-Benz LimitedWarranty.

! Because the ESP® operatesautomatically, the engine and ignition mustbe shut off (SmartKey in starter switchposition 0 or 1 or KEYLESS-GO start/stopbutton in position 0 or 1) when the parkingbrake is being tested on a brake testdynamometer. Such testing should be nolonger than 10 seconds.Active braking action through the ESP®

may otherwise seriously damage the brakesystem which is not covered by theMercedes-Benz Limited Warranty.

If your brake system is only subjected tomoderate loads, you should occasionally testthe effectiveness of the brakes by applyingabove-normal braking pressure at higherspeeds. This will also enhance the grip of thebrake pads.

G Warning!Make sure not to endanger any other roadusers when carrying out these brakingmaneuvers.

Refer to the description of the Brake AssistSystem (BAS) (Y page 63).

Parking brake When driving on wet roads or dirt coveredsurfaces, road salt and/or dirt can get intothe parking brake.To prevent corrosion and a reduction in thebraking power of the parking brake, observethe following:X From time to time, lightly engage the

parking brake before driving off.X Drive a distance of approximately 110 yds

(100 m) at a maximum speed of 12 mph(20 km/h).

G Warning!While performing this procedure pleaseassure that the vehicle is stopped beforeapplying the parking brake. Otherwise therear wheels could lock up. You could losecontrol of the vehicle and cause an accident.In addition, the vehicle’s brake lights do notlight up when the parking brake is engaged.Make sure not to endanger any other roadusers when you engage the parking brake.

Driving offWarm up the engine smoothly. Do not placefull load on the engine until the operatingtemperature has been reached.

! When driving off on a slippery surface, donot allow a drive wheel to spin for anextended period with the ESP® switchedoff. Doing so may cause serious damage tothe drivetrain which is not covered by theMercedes-Benz Limited Warranty.

! Simultaneously depressing theaccelerator pedal and applying the brakesreduces engine performance and causespremature brake and drivetrain wear whichis not covered by the Mercedes-BenzLimited Warranty.

HydroplaningDepending on the depth of the water layer onthe road, hydroplaning may occur, even at lowspeeds and with new tires. In heavy rain orwhen conditions indicate possiblehydroplaning:X Reduce vehicle speed.X Avoid track grooves in the road.X Apply brakes cautiously.

Standing water! Do not drive through flooded areas.

Before driving through water, determine itsdepth.If you must drive through standing water,drive slowly to prevent water from enteringthe passenger compartment or the enginecompartment. Water in these areas couldcause damage to electrical components orwiring of the engine or transmission, orcould result in water being ingested by theengine through the air intake causingsevere internal engine damage. Any suchdamage is not covered by the Mercedes-Benz Limited Warranty.

i Select the raised level (Y page 159)before driving through standing water.

For more information, see “Driving throughwater” (Y page 266).

Off-road driving

G Warning!Do not load items on the crossbars. It maycause instability during some maneuverswhich could result in an accident.Drive slowly in unknown terrain. This willmake it easier to recognize unexpectedobstacles and avoid damage to the vehicle.To help avoid the vehicle rolling over, neverturn it around on steep inclines. If the vehiclecannot complete the attempted climb, back itdown in reverse gear.Do not drive along the side of a slope. Thevehicle might otherwise rollover. If in doing sothe vehicle begins to show a tendency to roll,immediately steer into a line of gravity(straight up or downhill).Never let the vehicle roll backwards in idle.You may lose control of the vehicle if you useonly the service brake. For information ondriving downhill, see “Driving downhill”.

G Warning!Sand, dirt, mud and other material havingfriction property can cause exceptional wearand tear as well as brake failure.Have the brakes checked for dirt build-up andcleaned. There is otherwise a risk that fullbraking power may not be available in anemergency.

G Warning!Please be aware that by raising the vehiclelevel, the center of gravity also rises.Therefore, always ensure that the vehiclelevel is as low as possible. With higher rideheight the ESP® may activate earlier in certainsituations.

Read this chapter carefully before you beginoff-road travel.Familiarize yourself with the vehiclecharacteristics and gear changing before youattempt any difficult terrain off-road driving.

enhanced off-road package) (Y page 158)RAir suspension program (Y page 159)

Off-road driving rulesREngage the off-road driving program

(Y page 158) or LOW RANGE mode(Y page 120) before driving under off-roadconditions.RIf necessary, activate differential locks

(Y page 121).RMake sure you select a vehicle level

(Y page 159) appropriate to thetopographical conditions. Always makesure the vehicle has enough groundclearance.RFasten items being carried as securely as

possible (Y page 194).RAlways navigate gradients with the engine

on and with the transmission engaged in agear. Switch on the DSR (Y page 155) tohelp maintain a preset speed.

! Observe the following during off-roaddriving:RKeep doors, tailgate, windows, and tilt/

sliding sunroof closed whenever drivingoff-road.RAdjust vehicle speed to condition of

terrain. The more uneven, rutty andsteeper the terrain, the lower the speedshould be. Drive through water slowly atan even speed, avoiding a bow wave.RBe especially careful when driving in

unknown territory. It may be necessaryto get out of the vehicle and scout thepath you intend to take.RWatch out for obstacles, such as rocks,

holes, tree stumps and ruts.RBefore driving through water, determine

its depth.RDo not stop vehicle while immersed in

water, and do not shut off the engine.RIn sandy soil, drive at a steady speed as

allowed by conditions. This helpsovercome the vehicle rolling resistanceand reduces the likelihood of the vehiclesinking into the ground.RDo not initiate jumps with the vehicle. It

interrupts the forward momentum of thevehicle.RAlways drive onto slopes with the engine

running and the vehicle in gear.RDo not shift automatic transmission into

neutral position N.

G Warning!Do not reduce the tire inflation pressurebefore driving through sand. However, if youdo so, remember to correct the tire inflationpressure before continuing your trip. Drivingwith reduced tire inflation pressure increasesthe risk of losing control of the vehicle androlling over.

Checklist before off-road driving

Engine oil levelRCheck the engine oil level (Y page 230).

Only with a proper oil level can the vehicleobtain a trouble-free oil supply, even onsteep gradients.

! If the engine oil level warning lamp comeson while driving, stop the vehicle in a safelocation or as soon at is safe to do so.Check the engine oil level.The engine oil level warnings should not beignored. Extended driving with the symboldisplayed could result in serious enginedamage that is not covered by theMercedes-Benz Limited Warranty.

TiresRCheck the tread depth and maintain

specified tire inflation pressure. A placardwith the recommended tire inflationpressures is located on the driver’s door B-pillar (Y page 243).RCheck tires for possible damage and

remove foreign objects.RReplace missing valve caps.

RimsRDented or bent rims can cause tire inflation

pressure loss and damage the tire beads.For this reason, check and, if necessary,change rims before driving off-road.

Vehicle tool kitRCheck if the jack (Y page 286) is

functional.RAlways take the vehicle tool kit, a strong

tow rope, a shovel and a small plank (to putunder the jack on sandy soil) with you.

i For maximum engine speed, see“Tachometer” (Y page 125) and see vehiclespecification for your vehicle(Y page 362).RCheck the brakes after a lengthy

downgrade drive.

G Warning!Never turn the vehicle around on steepinclines. The vehicle might roll over. If thevehicle cannot complete the attempted climb,back it down in reverse gear.

i The hill-start assist system supports youwhen driving uphill.For more information, see “Hill-start assistsystem” (Y page 155).

Traction in steep terrainThe maximum vehicle climbing ability is a100% grade which is equivalent to a slopeangle of 45°. Keep in mind that the climbingability of the vehicle depends on terrainconditions.Be easy on the accelerator and watch forcontinuous wheel traction when driving insteep terrain.

i The 4-ETS helps greatly when starting outon a steep incline when the front wheelshave then the tendency to slip due to theweight shifting towards the rear axle.

The 4-ETS recognizes the situation andlimits the torque for the front wheels bybraking them.Simultaneously the torque for the rearwheels is increased.

i Vehicles with enhanced off-road packageare equipped with automatic locks for thecenter and rear axle differential to improvevehicle traction.

Driving across a hilltopDecelerate just ahead of a hilltop (do not shiftautomatic transmission into neutral positionN), to prevent the vehicle from speeding uptoo much after climbing a hill.Use the momentum of the vehicle to driveacross the hilltop.After climbing a hill, driving in this mannerprevents the vehicle from:Rlosing ground contact when cresting hillsRlosing its forward momentumRspeeding up too much after climbing the hill

Driving downhillRDrive slowly.RDo not drive at an angle to the incline. Steer

into the line of gravity and drive with thefront wheels pointing straight downhill.Otherwise, the vehicle may slide sidewaysoff the path and roll over.RShift automatic transmission into gear

Crossing obstacles

! Obstacles can damage the vehicleunderbody or suspension components. Ifpossible use the assistance of a secondperson outside the vehicle to scout thepath you intend to take and check foradequate ground clearance when you crossobstacles with your vehicle. The personassisting you outside the vehicle shouldalways be a safe distance away from thevehicle and positioned so that he or shecannot get hurt in case of any unexpectedvehicle movement.After off-road driving or crossing obstacles,inspect vehicle for any damage, especiallyvehicle underbody and suspensioncomponents. Failure to do so can adverselyaffect the vehicle’s future performance,including increased chance of an accident.

When driving over tree stumps, big rocks andother obstacles, observe the following rules:RMake sure the off-road driving program

(Y page 158) or if equipped theLOW RANGE mode (Y page 120) isswitched on.RAvoid high engine speeds.RShift automatic transmission into gear

range 1 (Y page 118).RCheck the vehicle clearance before

crossing obstacles.RCross obstacles (e.g. tree stumps or big

rocks) very slowly by aiming one of the front

wheels at the center of the obstacle, andrepeat same with the rear wheel.

! Special attention is needed when youcross obstacles on a steep incline.The vehicle could slide sideways as a resultof its possible slanted position which in turnmay result in the vehicle tipping or rollingover.

Driving on sand

G Warning!Do not reduce the tire inflation pressurebefore driving through sand. However, if youdo so, remember to correct the tire inflationpressure before continuing your trip. Drivingwith reduced tire inflation pressure increasesthe risk of losing control of the vehicle androlling over.

When driving on sand, observe the followingrules:RSet the raised level (Y page 159).RAvoid high engine speeds.RShift automatic transmission into a gear

range that is appropriate for the terrain.RIn sandy soil, drive at a steady speed as

conditions permit. This helps overcome thevehicle rolling resistance and reduce thelikelihood of the vehicle sinking into theground.RDrive in tracks of other vehicles if they are

not too deep and you have sufficientclearance.

Ruts A number of off-road tracks or other bywayshave deep ruts which can cause theunderbody to come in contact with theground.RMake sure the off-road driving program

them if at all possible.RIf the ruts are too deep to drive in, drive with

one side of the vehicle on the grassy centerstrip if the route permits.

Returning from off-road driving

G Warning!If you feel a sudden significant vibration orride disturbance, or you suspect that possibledamage to your vehicle has occurred, youshould turn on the hazard warning flashers,carefully slow down, and drive with caution toan area which is a safe distance from the road.Inspect the tires and the vehicle underbodyfor possible damage. If the vehicle or tiresappear unsafe, have the vehicle towed to thenearest authorized Mercedes-Benz Center ortire dealer for repairs.

Off-road driving increases strain on thevehicle.We recommend that you inspect the vehiclefor possible damage after each off-road trip.Recognizing any damage and a subsequenttimely repair reduces the chance of a possiblebreakdown or accident later on.

Proceed as follows:RSwitch off the off-road driving program

(Y page 158) or the LOW RANGE mode(Y page 120).RSwitch off the DSR (Y page 156).RSet the differential locks to AUTO

(Y page 122).RLower the vehicle back to a level suitable

for road conditions, e.g. highway/high-speed level (Y page 159).RClean all exterior lamps and check for

possible damage.RClean the front and rear license plate.RRemove excessive dirt from tires, wheels,

wheel housings, and underbody.For instance, after driving in mud, clean theradiator, chassis, engine, brakes, andwheels from extreme dirt using a strong jetof water.RCheck tires for possible damage.RInspect vehicle underbody, oil pan, brake

hoses, etc., as well as vehicle underbodyfor possible damage.RCheck for brush or branches caught in the

underbody.

! Brush or branches could increase thepossibility of a fire, as well as cut fuel and/or brake lines, puncture rubber bellows ofthe axles or drive shafts.RAfter continued operation in mud, sand,

water or other dirty conditions clean thebrake discs, wheels, brake pads and checkand clean axle joints.RConduct a brake test.

Trailer towing

G Warning!Failure to use proper equipment and drivingtechnique can result in a loss of vehiclecontrol when towing a trailer.Improper towing or failure to follow theinstructions in this manual can result invehicle damage and/or serious personalinjury. Follow the guidelines below carefullyto assure safe trailer operation.Contact an authorized Mercedes-Benz Centershould you require an explanation ofinformation contained in this manual.

Trailer hitch ROnly install a trailer hitch receiver approved

for your vehicle.For information on availability andinstallation, contact an authorizedMercedes-Benz Center.RThe bumpers on your vehicle are not

designed for use with clamp-type hitches.Do not attach rental hitches or otherbumper-type hitches to them.RTo reduce the possibility of damage,

remove the hitch ball adapter from thereceiver when not in use.

Electrical connections The vehicle is prewired to accept the seven-wire harness included in the Mercedes-Benzapproved trailer hitch receiver kit.

i A four-pole conversion plug is availablefrom your authorized Mercedes-BenzCenter as a spare part.

For further information, contact anauthorized Mercedes-Benz Center.

Vehicle and trailer weights and ratings The Gross Trailer Weight (GTW) is the weightof the trailer plus the weight of all cargo,equipment, luggage, etc. loaded on the

trailer. The maximum permissible GTW to betowed: 7 500 lb (3 402 kg).Trailer Tongue Weight Rating (TWR) is themaximum permissible weight on the trailertongue: 600 lb (272 kg) limit for Mercedes-Benz approved hitch receiver.

Loading a trailerRWhen loading a trailer, you should observe

that neither the permissible GTW, nor theGross Vehicle Weight Rating (GVWR) areexceeded. The GVWR is indicated on thecertification label located on the driver’sdoor B-pillar (Y page 242).Maximum permissible values are listed onthe safety compliance certification labelsfor the vehicle and for the trailer to betowed.The lowest value listed must be selectedwhen determining how the vehicle andtrailer are loaded.RThe tongue weight at the hitch ball must be

added to the rear axle weight to preventexceeding the rear Gross Axle WeightRating (GAWR). The GAWR is indicated onthe certification label located on thedriver’s door B-pillar (Y page 242).

i Mercedes-Benz recommends loading thetrailer in such a manner that it has a tongueweight between 8 % and 15 % of the GTW.

i The weight of other accessories,passengers and cargo will reduce themaximum trailer weight and tongue weightyour vehicle can tow.

Checking weights of vehicle and trailerRTo assure that the towing vehicle and trailer

are in compliance with the maximumpermissible weight limits, have the loadedrig (towing vehicle including driver,passengers and cargo, trailer fully loaded)weighed on a commercial scale.RCheck the vehicle’s front and rear gross

axle weight, the Gross Trailer Weight (GTW)and tongue weight.

The values as measured must not exceedthe weight limits listed under “Vehicle andtrailer weights and ratings” (Y page 269).

Coupling a trailer

G Warning!While you are coupling or decoupling a trailer,make sure nobody locks or unlocks thevehicle and/or opens or closes doors or thetailgate.The vehicle’s level could change and youcould endanger yourself and/or others as aresult.Make sure that you do not operate the ADSbutton or the vehicle level control systemwhen coupling/decoupling the trailer.

Observe maximum permitted trailerdimensions (width and length).Most states and all Canadian provincesrequireRsafety chains between the towing vehicle

and the trailerThe chains should be criss-crossed underthe trailer tongue. They must be attachedto the hitch receiver, and not to thevehicle’s bumper or axle.Make sure to leave enough slack in thechains to permit turning corners.Ra separate brake system at various trailer

weightsRa break-away switch on trailers with a

separate brake system.Check with your local state laws for specificrequirements.The switch activates the trailer brakes inthe possible event that the trailer mightseparate from the tow vehicle.

! Do not connect a trailer brake system (iftrailer is so equipped) directly to thevehicle’s hydraulic brake system, as yourvehicle is equipped with antilock brakes. Ifyou do, neither the vehicle’s brakes nor thetrailer’s brakes will function properly.

i The provided vehicle electrical wiringharness for trailer towing has a brake signalwire for hook-up to a brake controller.

i When you are towing a trailer, the vehiclelevel always remains in the highway setting.The following applies additionally whentowing a trailer:RThe vehicle is lowered to the highway

level when it reaches a speed of 5 mph(8 km/h) if not set to highway level.RThe highspeed level is not available.The restrictions that apply to towing alsoapply when using accessories that areconnected to the trailer power socket, suchas a bicycle rack.

Towing a trailer There are many different laws, includingspeed limit restrictions, having to do withtrailer towing. Make sure your rig will be legal,not only for where you reside, but also forwhere you will be driving. A good source forthis information can be the police or localauthorities.Note the following, when driving with a trailer:RIn order to gain skill and an understanding

of the vehicle’s behavior, you should

practice turning, stopping and backing upin an area which is free of traffic.RBefore you start driving check the

- trailer hitch- break-away switch- safety chains- electrical connections- lighting- tires

RAdjust the mirrors (Y page 94) to permitunobstructed view beyond rear of trailer.RIf the trailer has electric brakes, start your

vehicle and trailer moving slowly, and thenapply only the trailer brake controller byhand to make sure the brakes are workingproperly.RAlways secure items in the trailer to

prevent load shifts while driving.RWhen towing a trailer, check occasionally

to make sure the load is secure, and thattrailer lighting and brakes (if so equipped)are functioning properly.RTake into consideration that when towing a

trailer, the handling characteristics aredifferent and less stable from those whenoperating the vehicle without a trailer.It is important to avoid sudden maneuvers.RThe vehicle and trailer combination is

heavier, and therefore limited inacceleration and climbing ability, and has alarger braking distance.It is more prone to reacting to cross windgusts, and requires more sensitive steeringinput.RIf possible, do not brake abruptly, but

rather engage the brake slightly at first topermit the trailer to activate its brake. Thenincrease the braking force.

! If the trailer should begin to sway, reducethe vehicle’s speed immediately.

Do not attempt to straighten out the towvehicle and trailer by increasing the speed.RIf the transmission shifts between gears on

inclines repeatedly, shift to a lower gearrange manually (Y page 118). Select 4, 3,2 or 1.A lower gear and reduction of speedreduces the chance of engine overloadingand/or overheating.ROn very steep inclines, not manageable

with automatic transmission in gear range1, switch on off-road driving program(Y page 158) or LOW RANGE mode(Y page 120).RWhen going down an incline, shift into a

lower gear and use the engine’s brakingeffect.Avoid riding the brakes, thus overheatingthe vehicle and trailer brakes (if soequipped).RIf the engine coolant rises to an extremely

high temperature when the air conditioningis on, turn off the air conditioning system.Engine coolant heat can be additionallyvented by opening the windows, switchingthe climate control fan speed to high andsetting the temperature control to themaximum.RDuring a passing maneuver extreme care

must be exercised since your vehicle witha trailer will require additional passingdistance ahead than when driving withouta trailer.Because your vehicle and trailer is longerthan your vehicle alone, you will also needto go much farther ahead of the passedvehicle before you can return to your lane.

It is 50 miles(80 km) if the vehicle is partially loaded and18 miles (30 km) if the vehicle is fully loaded.The point at which the maximum drivingdistance in emergency mode begins is whenthe warning message appears in themultifunction display indicating that there isa loss of tire inflation pressure.X Do not exceed the maximum speed of

50 mph (80 km/h).

G Warning!In emergency mode, your vehicle’s drivingcharacteristics are diminished in suchsituations as:Rdriving around curvesRwhile brakingRwhile accelerating rapidly

Therefore, your driving style must be adaptedaccordingly. Avoid abrupt steering and drivingmaneuvers, as well as driving over obstacles(road curbs, potholes, or off-road areas). Thisis especially important if the vehicle is heavilyloaded.The emergency driving distance that can beachieved greatly depends on the demandsplaced on the vehicle. Depending on speed,load, driving maneuvers, road conditions,outside temperature, etc., the distance can besignificantly shorter or, if the vehicle is drivencautiously, somewhat longer.Do not continue driving in emergency mode ifRyou notice knocking soundsRthe vehicle starts to shakeRsmoke develops and you smell rubberRESP® is intervening continuouslyRyou notice tears on the tire sidewalls

After driving in emergency mode, you musthave the rims inspected by an authorizedMercedes-Benz Center to check if they aresuitable for further use. The failed tire mustbe replaced in any case.

When replacing individual or all tires on thevehicle, make sure only tires marked with“MOExtended” are mounted in the sizespecified for your vehicle (Y page 365).

Rims and tires

Notes! Only use tires which have been tested and

approved by Mercedes-Benz. Tiresapproved by Mercedes-Benz are developedto provide best possible performance inconjunction with the driving safety systemson your vehicle such as the ABS or theESP®. Tires specially developed for yourvehicle and tested and approved byMercedes-Benz can be identified by findingthe following on the tire’s sidewall:RMO = Mercedes-Benz Original

equipment tiresRMOE = Mercedes-Benz Original Extended

(tires with limited run-flatcharacteristics) original equipment tires

Using tires other than those approved byMercedes-Benz may result in damage thatis not covered by the Mercedes-BenzLimited Warranty.

For information on driving with MOExtendedtires, see the “Practical hints” section(Y page 345).

i Vehicles with MOExtended system arenot factory-equipped with a TIREFIT kit.When retrofitting with tires that do not haverun-flat characteristics, you should alsoequip your vehicle with a TIREFIT kit.TIREFIT kits are available at any authorizedMercedes-Benz Center.

! Using tires other than those approved byMercedes-Benz can have detrimentaleffects, such asRpoor handling characteristicsRincreased noiseRincreased fuel consumptionMoreover, tires and rims not approved byMercedes-Benz may, under load, exhibitdimensional variations and different tiredeformation characteristics that couldcause them to come into contact with the

vehicle body or axle parts. Damage to thetires or the vehicle may be the result.

i Further information on tires and rims isavailable at any authorized Mercedes-BenzCenter. The Tire and Loading Informationplacard with the recommended tireinflation pressures for cold tires is locatedon the driver’s door B-pillar. Supplementaltire inflation pressure information fordriving at high speeds or for vehicle loadsless than the maximum loaded vehiclecondition can be found on the tire inflationpressure label. The tire inflation pressurelabel is located on the inside of the fuel fillerflap. The tire inflation pressure should bechecked regularly and should only beadjusted on cold tires. Follow tiremanufacturer’s maintenancerecommendation included with the vehicle.

For information on recommended tireinflation pressure and supplemental tireinflation pressure information for specialdriving situations, see (Y page 234).

i Please keep in mind that the vehicle mustbe equippedRwith wheels of identical dimensions on

each axle (left and right)Rwith tires of identical characteristics all

around, i.e. summer tires, winter tires,all-season tires, or MOExtended tires etc.

i The following pages also list the approvedrim and tire sizes for equipping your vehiclewith winter tires. Winter tires are notavailable as standard or optional factoryequipment, but can be purchased from anauthorized Mercedes-Benz Center.Equipping your vehicle with winter tiresapproved for your vehicle model mayrequire the purchase of rims of therecommended size for use with thesewinter tires.

Engine oil additives! Do not blend oil additives with engine oil.

They may damage the engine. Damage ormalfunctions resulting from blending oiladditives are not covered by the Mercedes-Benz Limited Warranty.

Air conditioning refrigerantR134a (HFC) refrigerant and special PAGlubricating oil are used in the air conditioningsystem.

! Never use R 12 (CFC) or mineral-basedlubricating oil. Otherwise damage to thesystem will occur.

Brake fluid

G Warning!During vehicle operation, the boiling point ofthe brake fluid is continuously reducedthrough the absorption of moisture from theatmosphere.Under extremely strenuous operatingconditions, this moisture content can lead tothe formation of bubbles in the system, thusreducing the system’s efficiency.Therefore, the brake fluid must be replacedregularly. Refer to your vehicle’s MaintenanceBooklet for replacement interval.

Only brake fluid approved by Mercedes-Benzis recommended. Any authorized Mercedes-Benz Center will provide you with additionalinformation.

Premium unleaded gasoline (gasoline engine)

G Warning!Gasoline is highly flammable and poisonous.It burns violently and can cause seriouspersonal injury.

Never allow sparks, flames or smokingmaterials near gasoline!Turn off the engine before refueling.Whenever you are around gasoline, avoidinhaling fumes and any skin or clothingcontact. Extinguish all smoking materials.Direct skin contact with fuels and theinhalation of fuel vapors are damaging yourhealth.

! To maintain the engine’s durability andperformance, premium unleaded gasolinemust be used.If premium unleaded gasoline is notavailable and low octane gasoline is used,follow these precautions:RHave the fuel tank only partially filled

with unleaded regular gasoline and fill upwith premium unleaded gasoline as soonas possible.RAvoid full throttle driving and abrupt

acceleration.RDo not exceed an engine speed of

3 000 rpm if the vehicle is loaded with alight load such as two persons and noluggage.RDo not exceed 2/3 of maximum

accelerator pedal position if the vehicleis fully loaded or operating inmountainous terrain.

Fuel requirements

Gasoline engineOnly use premium unleaded gasoline. Theoctane number (posted at the pump) must be91 min. It is an average of both the ResearchOctane Number (RON) and the Motor OctaneNumber (MON): (RON+MON)/2. This is alsoknown as the ANTI-KNOCK INDEX.Reformulated gasolines (RFG) and/orunleaded gasoline containing oxygenatessuch as ethanol, TAME, ETBE, IPA, IBA, and

TBA can be used provided the ratio of any oneof these oxygenates to gasoline does notexceed 10%; MTBE must not exceed 15%.The ratio of methanol to gasoline must notexceed 3% plus additional cosolvents.Using mixtures of ethanol and methanol is notallowed. Gasohol, which contains 10%ethanol and 90% unleaded gasoline, can beused.These blends must also meet all other fuelrequirements, such as resistance to sparkknock, boiling range, vapor pressure, etc.

Diesel engine Only use commercially available vehicularULTRA-LOW SULFUR HIGHWAY DIESEL FUEL(ULSD, 15 ppm SULFUR MAXIMUM) thatmeets the ASTM D975 standard. Failure touse ULTRA-LOW SULFUR HIGHWAY DIESELFUEL (ULSD) can severely damage thevehicle’s exhaust after-treatment device.To prevent malfunctions, diesel fuel withimproved cold flow characteristics is offeredin the winter months. Check with your fuelretailer.

! Do not fill the tank with gasoline. Do notblend diesel fuel with gasoline or kerosene.The fuel system and engine will otherwisebe damaged, which is not covered by theMercedes-Benz Limited Warranty.

For further information on diesel fuel pumplabeling, contact an authorized Mercedes-Benz Center or visit www.mbusa.com (USAonly).

Biodiesel (FAME = Fatty Acid Methyl Ester) containing fuelsMercedes-Benz USA approves the use of B5(standard ULSD which may contain amaximum of 5% biodiesel) in all Common-railinjection (CDI) and BlueTEC diesel engines.Diesel fuels containing a higher percentage ofbiodiesel, e.g. B20, as well as straightbiodiesel may cause severe damage to yourengine/fuel system and are not approved.

Please ask your service station personnel forfurther information. If the B5 biodiesel blendis not sufficiently labeled to clearly indicatethat it meets the ULSD standard, please donot use it.The Mercedes-Benz Limited Warranty doesnot cover damages caused by the use of fuelsnot meeting Mercedes-Benz approved fuelstandards.

Gasoline additives (gasoline engine)A major concern among enginemanufacturers is carbon build-up caused bygasoline. Mercedes-Benz recommends onlythe use of quality gasoline containingadditives that prevent the build-up of carbondeposits.After an extended period of using fuelswithout such additives carbon deposits canbuild up, especially on the intake valves andin the combustion area, leading to engineperformance problems such as:RWarm-up hesitationRUnstable idleRKnocking/pingingRMisfireRPower lossIn areas where carbon deposits may beencountered due to lack of availability ofgasoline which contains these additives, theuse of Mercedes-Benz approved additives isrecommended.Contact an authorized Mercedes-Benz Centeror visit www.mbusa.com (USA only) for alisting of approved products. Followdirections on the product label.Do not blend other fuel additives with fuel.This only results in unnecessary cost and maybe harmful to the engine operation.

AdBlue®

AdBlue® is a non-flammable, non-toxic,colorless and odorless, water-soluble liquid.

! Only use AdBlue® complying withISO 22241. Do not blend with additives.

! Rinse surfaces that have come intocontact with AdBlue®, or remove AdBlue®

with a moist cloth and cold waterimmediately. If AdBlue® has crystallizedalready, use cold water and a sponge.AdBlue® residues will crystallize and soilthe affected surfaces.

High ambient temperaturesIf AdBlue® in the reservoir heats up to above122‡ (50†) for a long period of time, forexample due to direct sunlight, ammonia gasvapors may escape when opening theAdBlue® tank.

G Warning!When opening the filler cap of the AdBlue®

tank ammonia gas vapors may escape. RefillAdBlue® in a well ventilated area only.Ammonia gas vapors have a pungent odor andare particularly irritating for your skin,mucous membranes, and eyes. Inhalingammonia gas vapors will cause burning eyes,nose, and throat, as well as coughing andwatering eyes.

Low ambient temperaturesAdBlue® freezes at a temperature ofapproximately 12‡ (-11†). Your vehicle isfactory equipped with an AdBlue® preheatingsystem. The vehicle can thus be operated attemperatures below 12‡ (-11†).

Special additives

! Only use AdBlue® complying withISO 22241. Do not add additives toAdBlue® and do not dilute AdBlue® withwater. Otherwise, the BlueTEC exhaust gasaftertreatment system could be damaged.Damage caused by using additives ordiluting with water are not covered by theMercedes-Benz Limited Warranty.

PurityThe purity of AdBlue® is of particularimportance for avoiding malfunctions in theexhaust gas aftertreatment.If AdBlue® is pumped out of the tank, e.g.during repair work, the same liquid must notbe used to refill the tank as its purity is nolonger guaranteed.

! Impurities caused for example by otherservice products, cleaning agents, and dustresult in increased emissions,malfunctions, catalyst damage, or enginedamage.

CoolantsThe engine coolant is a mixture of water andanticorrosion/antifreeze, which provides:RCorrosion protectionRFreeze protectionRBoiling protection (by increasing the boiling

point)The cooling system was filled at the factorywith a coolant providing freeze protection toapproximately -35‡ (-37†) and corrosionprotection.

! Add premixed coolant solution only.Adding water and MB 325.0 Anticorrosion/Antifreeze separately from each other,could cause engine damage not covered bythe Mercedes-Benz Limited Warranty.

If the antifreeze mixture is effective to -35‡(-37†), the boiling point of the coolant in thepressurized cooling system is reached atapproximately 266‡ (130†).The coolant solution must be used year roundto provide the necessary corrosion protectionand increase boil-over protection. Refer tothe Maintenance Booklet for replacementinterval.Coolant system design and coolant useddetermine the replacement interval. Thereplacement interval published in theMaintenance Booklet is only applicable ifMB 325.0 Anticorrosion/Antifreeze solutionor other Mercedes-Benz approved productsof equal specification are used to renew thecoolant concentration or bring it back up tothe proper level.For information on other Mercedes-Benzapproved products of equal specification,contact an authorized Mercedes-Benz Centeror visit www.mbusa.com (USA only).To provide important corrosion protection,the solution must be at least 50%anticorrosion/antifreeze (equivalent tofreeze protection to approximately -35‡[-37†]).If you use a solution that is more than 55%anticorrosion/antifreeze (freeze protectionto approximately -49‡ [-45†]), the enginetemperature will increase due to the lowerheat transfer capability of the solution.Therefore, do not use more than this amountof anticorrosion/antifreeze.

If the coolant level is low, water and MB 325.0Anticorrosion/Antifreeze should be used tobring it up to the proper level (have coolingsystem checked for signs of leakage). Pleasemake sure the mixture is in accordance withlabel instructions.The water in the cooling system must meetminimum requirements, which are usuallysatisfied by normal drinking water.If you are not sure about the water quality,contact an authorized Mercedes-BenzCenter.

Anticorrosion/antifreeze Your vehicle contains a number of aluminumparts. The use of aluminum components inmotor vehicle engines necessitates thatanticorrosion/antifreeze coolant used insuch engines be specifically formulated toprotect the aluminum parts. Failure to usesuch anticorrosion/antifreeze coolant willresult in a significantly shortened service life.Therefore, the following product is stronglyrecommended for use in your vehicle:MB 325.0 Anticorrosion/Antifreeze agent.Before the start of the winter season (or oncea year in hot southern regions), you shouldhave the anticorrosion/antifreezeconcentration checked.The coolant is also regularly checked eachtime you bring your vehicle to an authorizedMercedes-Benz Center for service.
