i This Operator’s Manual describes allfeatures, standard or optional, potentiallyavailable for your vehicle at the time ofpurchase. Please be aware that yourvehicle might not be equipped with allfeatures described in this manual.

Occupant safety

IntroductionIn this section you will learn the mostimportant facts about the restraint systemcomponents of the vehicle.The restraint systems areRSeat 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

RActive head restraintsRAir 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 withBabySmartTM air bag deactivationsystem

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 For information on infants and childrentraveling with you in the vehicle andrestraint systems for infants and children,see “Children in the vehicle”(Y page 54).

SRS indicator lampThe SRS system conducts a self-test whenthe ignition is switched on and in regularintervals while the engine is running. Thisfacilitates detection of system malfunctions.The 6 indicator lamp in the instrumentcluster comes on when the ignition isswitched on and goes out no later than a fewseconds after the engine has been started.The SRS components are in operationalreadiness if the 6 indicator lamp is not litwhen the engine is running.A malfunction in the system has beendetected if the 6 indicator lampRfails to go out after approximately

4 seconds after the engine is startedRdoes not come on at allRcomes on after the engine was started or

G Warning!In the event that the 6 indicator lampcomes on while driving or does not come onat all, the SRS self-check has detected amalfunction. For your safety, we stronglyrecommend that you contact an authorizedMercedes-Benz Center immediately to havethe system checked; otherwise the SRS maynot deploy when needed in an accident, whichcould result in serious or fatal injury, or itmight deploy unexpectedly and unnecessarilywhich could also result in injury.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 Centeror call our Customer Assistance Center at1-800-FOR-MERCedes (1-800-367-6372) fordetails.

Air bags

G Warning!Air bags are designed to reduce the potentialof injury and fatality in certain frontal impacts(front air bags), side impacts (side impact airbags, window curtain air bags and pelvic airbags), or rollovers (window curtain air bags).However, no system available today cancompletely eliminate injuries and fatalities.The deployment of the air bags temporarilyreleases a small amount of dust from the airbags. This dust, however, is neither injuriousto 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 the

vehicle 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 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. Ifyou 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 aspossible 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 authorizedBabySmartTM compatible child seat, whichoperates with the BabySmartTM 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 the rearseat.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,properly use the seat belts, 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 certainfrontal impacts (front air bags), side impacts(side impact air bags, pelvic air bags andwindow curtain air bags) which exceed presetdeployment thresholds, and in certainrollovers (window curtain air bags). Only inthe event of such a situation will they providetheir 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 that you replace deployed airbags and repair any malfunctioning air bagsto make sure the vehicle will continue toprovide supplemental crash protection foroccupants.

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 and their anchoringpoints must also be checked. Only use seatbelts installed 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 is deployed must be replaced.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.This includes changing or removing anycomponent or part of the SRS, theinstallation of additional trim material, seatcovers, badges, etc. over the steeringwheel hub, front passenger front air bagcover, outboard sides of the seatbackrests, door trim panels, or door frametrims, and installation of additionalelectrical/electronic equipment on or nearSRS components and wiring. Keep areabetween 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.RIn addition, improper repair work on the

SRS creates a risk of rendering the SRSinoperative or causing unintended air bagdeployment. Work on the SRS musttherefore only be performed by qualifiedtechnicians. Contact an authorizedMercedes-Benz Center.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 SRSand refer them to the applicable section in theOperator’s Manual.

Occupant Classification SystemThe Occupant Classification System (OCS) isstandard equipment in USA.The OCS automatically turns the frontpassenger front air bag on or off based on theclassified occupant weight categorydetermined by weight sensor readings fromthe front passenger seat.The system does not deactivate the frontpassenger side impact air bag, the pelvic airbag, the window curtain air bag and theEmergency Tensioning Devices (ETDs).Occupants must sit with the seat beltproperly fastened in a position that is asupright as possible with their back against theseat backrest and feet on the floor to becorrectly classified. If the occupant’s weightis transferred to another object in the vehicle(e.g. by leaning on armrests), the OCS maynot be able to properly approximate theoccupant’s weight category.

i If your seat, including the trim cover andcushion, needs to be serviced in any way,take the vehicle to an authorizedMercedes-Benz Center.

Only seat accessories approved byMercedes-Benz may be used.Both the driver and the front passengershould always use the 45 indicatorlamp as an indication of whether or not thefront passenger is properly positioned.

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 54).

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 yourseat 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 as

possible 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 and their anchoring points mustalso 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.

Active head restraints (except C 63AMG)

The active head restraints are intended tooffer the driver and front passenger increasedprotection from whiplash-type injuries. In theevent of a rear-end collision, the active headrestraints on the driver’s and frontpassenger’s seat are designed to moveforward in the direction of travel, providingthe head with increased support earlier on inthe collision sequence. The active headrestraints move forward whether the seat isoccupied or not.

G Warning!Do not attach any objects (e.g. hangers) to thehead restraint posts. Otherwise, the activehead restraints may not be able to functionproperly or offer the intended degree ofprotection they were designed for in the eventof a rear-end collision.

If the active head restraints have beentriggered in an accident, the active headrestraints must be reset. Otherwise, theactive head restraints cannot offer anyadditional protection in the event of anotherrear-end collision.For information on resetting the activatedactive head restraints, see “Resettingactivated head restraints” (Y page 308).You cannot remove the active head restrainton the driver’s and front passenger’s seats.

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 theactive head restraints and/or the deploymentof the front side impact air bags.Contact an authorized Mercedes-Benz Centerfor availability.

G Warning!For your protection, drive only with properlypositioned head restraints.Adjust the head restraint so that it is as closeto the head as possible and the center of thehead restraint supports the back of the headat eye level. This will reduce the potential forinjury to the head and neck in the event of anaccident or similar situation.

Driving safety systems

IntroductionThis section contains information about thefollowing driving safety systems:RABS (Antilock Brake System)RAdaptive BrakeRBAS (Brake Assist System)REBP (Electronic Brake Proportioning)RESP® (Electronic Stability Program)

i In winter operation, the maximumeffectiveness of most of the drivingsystems described in this section is onlyachieved 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 60.

G Warning!Do not pump the brake pedal. Use firm, steadybrake pedal pressure instead. Pumping thebrake pedal defeats the purpose of the ABSand 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 ! indicator lamp in the instrumentcluster comes on when you switch on theignition. It goes out when the engine isrunning.

BrakingAt the instant one of the wheels is about tolock up, a slight pulsation can be felt in thebrake pedal, indicating that the ABS is in theregulating 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 and

functions 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.

BAS

G Observe Safety notes, see page 60.The Brake Assist System (BAS) operates inemergency situations. If you apply the brakesvery quickly, the BAS automatically providesfull brake boost, thereby potentially reducingthe 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.

Adaptive BrakeAdaptive Brake provides a high level ofbraking safety as well as increased brakingcomfort. It is coupled with the ABS, theESP® and the BAS. Adaptive Brake takesdriver and vehicle characteristics intoconsideration, thus achieving an optimalbraking effect.For more information on the brake system,see (Y page 257).

EBP

G Observe Safety notes, see page 60.The Electronic Brake Proportioning (EBP)enhances braking effectiveness by allowingthe rear brakes to supply a greater proportionof 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 60.The Electronic Stability Program (ESP®) isoperational as soon as the engine is runningand monitors the vehicle’s traction (force ofadhesive friction between the tires and theroad surface) and handling.The ESP® recognizes when a wheel isspinning or if the vehicle starts to skid. Byapplying brakes to individual wheels and bylimiting the engine output, the ESP® works tostabilize the vehicle. The ESP® is especiallyuseful while driving off and on wet or slippery

road surfaces. The ESP® also stabilizes thevehicle during braking and steeringmaneuvers.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.

! Vehicles with 4MATIC: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.

! Vehicles with 4MATIC:Because the ESP® operates automatically,the engine and ignition must be shut off(SmartKey in starter switch position 0 or1 or KEYLESS-GO start/stop button inposition 0 or 1) when the parking brake isbeing tested on a brake test dynamometer.

Active braking action through the ESP®

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

! Vehicles without 4MATIC:Because the ESP® operates automatically,the engine and ignition must be shut off(SmartKey in starter switch position 0 or1 or KEYLESS-GO start/stop button inposition 0 or 1) when the parking brake isbeing tested on a brake test dynamometeror the vehicle is being towed with the frontaxle raised.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 cruise control switches offautomatically when the ESP® engages.

Electronic Traction System(ETS/4-ETS)

G Observe Safety notes, see page 60.The ETS (Electronic Traction System) and4-ETS (four-wheel Electronic TractionSystem, vehicles with 4MATIC only) arecomponents of the ESP®. The ETS/4-ETSimproves the vehicle’s ability to utilizeavailable traction, especially under slipperyroad conditions by applying the brakes to aspinning wheel. Vehicles with 4MATIC alsotransfer more power to the wheel(s) withtraction.When you switch off the ESP®, theETS/4-ETS is still enabled.

Safety notes

G Warning!In order to avoid possible loss of vehiclecontrol, all seat, head restraint, steeringwheel, and rear view mirror adjustments, aswell as fastening of seat belts, must be donebefore the vehicle is put into motion.

G Warning!Do not adjust the driver’s seat while driving.Adjusting the seat while driving could causethe driver to lose control of the vehicle.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 fatal injuries. The seat backrest and seatbelts provide the best restraint when thewearer is in a position that is as upright aspossible and seat belts are properlypositioned on the body.

G Warning!Your seat must be adjusted so that you cancorrectly fasten your seat belt.Observe the following points:RAdjust the seat backrest until your arms are

slightly angled when holding the steeringwheel.RAdjust the seat to a comfortable seating

position that still allows you to reach theaccelerator/brake pedal safely. Theposition should be as far back as possible

with the driver still able to operate thecontrols properly.RAdjust the head restraint so that it is as

close to the head as possible and the centerof the head restraint supports the back ofthe head at eye level.RNever place hands under the seat or near

any moving parts while a seat is beingadjusted.

Failure to do so could result in an accidentand/or serious personal injury.

G Warning!The power seats can be operated at any time.Therefore, do not leave children unattendedin the vehicle, or with access to an unlockedvehicle. A child’s unsupervised access to avehicle could result in an accident and/orserious personal injury.

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!For your protection, drive only with properlypositioned head restraints.Adjust the head restraint so that it is as closeto the head as possible and the center of thehead restraint supports the back of the headat eye level. This will reduce the potential for

Coolant temperature gaugeThe coolant temperature gauge is located onthe left side in the instrument cluster(Y page 28).

G Warning!Driving when your engine is overheated cancause some fluids which may have leaked intothe engine compartment to catch fire. Youcould be seriously burned.Steam from an overheated engine can causeserious burns which can occur just by openingthe engine hood. Stay away from the engineif you see or hear steam coming from it.Stop the vehicle in a safe location away fromother traffic. Turn off the engine, get out of thevehicle and do not stand near the vehicle untilthe engine has cooled down.

During severe operating conditions, e.g. stop-and-go traffic, the coolant temperature mayrise close to 248‡ (120†), i.e close to thered zone of the temperature gauge.

! Excessive coolant temperature triggers awarning in the multifunction display.The engine should not be operated with acoolant temperature above 248‡ (120†),i.e. in the red zone of the coolanttemperature gauge. Doing so may causeserious engine damage which is notcovered by the Mercedes-Benz LimitedWarranty.

Permissible media for MP3/WMA filesRCD-RRCD-RW

Permissible file systemsRISO9660/Joliet for CDs

Multisession CDsFor multisession CDs, the first session typeof the CD determines how the audio systemwill process the CD.For example, if the first session type isaccording to the audio CD standard and thesecond session type is according to the dataCD standard containing MP3/WMA tracks,the audio system will treat the CD as aconventional audio CD. This means that it isonly possible to access the audio CD tracks.Access to the MP3/WMA tracks is notpossible.Similarly, if the first session type is accordingto the data CD standard containing MP3/WMA tracks and the second session type isaccording to the audio CD standard, the audiosystem will treat the CD as a data CD. Thismeans that it is only possible to access theMP3/WMA tracks. Access to the audio CDtracks is not possible.

driving mode, Canada onlyRParktronic system, Canada onlyThe ABS, Adaptive Brake, BAS, EBP andESP® driving safety systems are described inthe “Safety and security” section(Y page 60).

Cruise controlThe cruise control automatically maintainsthe speed you set for your vehicle.The use of the cruise control is recommendedfor driving at a constant speed for extendedperiods of time.The currently set speed or last set speed(“Resume” function) appears in the

multifunction display for approximately5 seconds. The corresponding cruise controlspeed segments : from the selected speedto the vehicle maximum speed in themultifunction display are illuminated.

G Warning!The cruise control is a convenience systemdesigned to assist the driver during vehicleoperation. The driver is and must alwaysremain responsible for the vehicle’s speedand for safe brake operation.Only use the cruise control if the road, traffic,and weather conditions make it advisable totravel at a constant speed.RThe use of the cruise control can be

dangerous on winding roads or in heavytraffic because conditions do not allow safedriving at a constant speed.RThe use of the cruise control can be

dangerous on slippery roads. Rapidchanges in tire traction can result in wheelspin and loss of control.RDeactivate the cruise control when driving

in fog.

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

Atlower speeds, the Parktronic system switcheson again.The Parktronic system also deactivates whenyou shift the automatic transmission intopark position P or engage the parking brake.The Parktronic system monitors thesurroundings of your vehicle with six sensorsin the front bumper and four sensors in therear bumper.

Example illustration, sensors in the front bumper

To function properly, sensors : must be freeof dirt, ice, snow and slush. Cleansensors : regularly, being careful not to

scratch or damage sensors :, see “Cleaningthe Parktronic system sensors”(Y page 265).

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.

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 afaster 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.

in 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 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 are

sharply 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 resultin handling or steering problems, or brakefailure.

If your vehicle has tires of adifferent size than the size indicated on theTire and Loading Information placard or, ifavailable, the tire inflation pressure label, youshould determine the proper tire inflationpressure for 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 subsequent

vehicle start-ups as long as the malfunctionexists. When the malfunction indicator isilluminated, the system may not be able todetect or signal low tire pressure as intended.TPMS malfunctions may occur for a variety ofreasons, including the installation ofincompatible replacement or alternate tiresor wheels on the vehicle that prevent theTPMS from functioning properly. Alwayscheck the TPMS malfunction telltale afterreplacing one or more tires or wheels on yourvehicle to ensure that the replacement oralternate tires and wheels allow the TPMS tocontinue to function properly.

i If a condition causing the TPMS tomalfunction develops, it may take up to10 minutes for the system to signal amalfunction using the TPMS telltaleflashing and illumination sequence.The telltale extinguishes after a fewminutes driving if the malfunction has beencorrected.

i Operating radio transmission equipment(e.g. wireless headsets, two-way radios) inor near the vehicle could cause the TPMSto malfunction.

i This device complies with Part 15 of theFCC Rules. Operation is subject to thefollowing two conditions:1. This device may not cause harmful

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 (ifapplicable) should never exceed the weightreferenced in that statement.

Seating capacity

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 240).

i Data shown on Tire and LoadingInformation 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.

Steps for determining correct load limitThe 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 2: Determine the combined weight ofthe driver and passengers that will be ridingin your vehicle.

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).

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 everyother week. For more information onchecking tire inflation pressure, see“Recommended tire inflation pressure”(Y page 233).

Tire inspectionEvery time you check the tire inflationpressure, you should also inspect your tiresfor the following:Rexcessive treadwear (Y page 245)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). Therecommended 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 GradingStandards

The Uniform Tire Quality Grading is a U.S.Government requirement designed to givedrivers consistent and reliable informationregarding tire performance. Tiremanufacturers are required to grade tires

based 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.

TreadwearThe 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 tractiontests, 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 254) 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 causeexcessive heat build-up and possible tirefailure.

The temperature grades are A (the highest),B, and C, representing the tire’s resistance to

the 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. Wheels could becomeloose if not tightened with a torque of96 lb-ft (130 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 244).In some cases, such as when your vehicle isequipped with mixed-size tires (different tiredimension front vs. rear), tire rotation is notpossible.If applicable to your vehicle’s tireconfiguration, tires can be rotated according

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 249).

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

Tire load ratingG 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.

Tire load rating A is a numerical codeassociated with the maximum load a tire cansupport.For example, a load rating of 91 correspondsto a maximum load of 1356 lb (615 kg) thetire is designed to support. See also“Maximum tire load” (Y page 244) where themaximum load associated with the load indexis indicated in kilograms and lbs.For additional information on tire load rating,see “Load identification” (Y page 251).

Tire speed ratingG Warning!Even when permitted by law, never operate avehicle at speeds greater than the maximumspeed rating of the tires.Exceeding the maximum speed for which tiresare rated can lead to sudden tire failure,causing loss of vehicle control and possiblyresulting in an accident and/or seriouspersonal injury and possible death, for youand for others.

Regardless of the tire speed rating, localspeed limits should be obeyed. Use prudentdriving speeds appropriate to prevailingconditions.Tire speed rating B indicates the approvedmaximum speed for the tire.

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 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 340).Always observe the speed rating of the wintertires installed on your vehicle.

Snow chains! Some tire sizes do not leave adequate

clearance 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 exceed

30 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 340).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 localand 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 61)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 loss of control.

The most important rule for slippery or icyroads is to drive sensibly and to avoid abruptacceleration, braking and steeringmaneuvers. Do not use the cruise controlsystem under such conditions.When the vehicle is in danger of skidding, shiftthe automatic transmission to neutralposition N or declutch in case of manualtransmission. Try to keep the vehicle undercontrol by corrective steering action.

i For information on driving with snowchains, see “Snow chains” (Y page 255).

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 roof rack 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 theMaintenance 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 service brake when the engine is notrunning.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, thefirst 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

be too low if the red brake warning lamp inthe instrument cluster comes on while theengine is running and an acoustic warningsounds. Observe additional messages inthe multifunction display 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.

! Vehicles with 4MATIC: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 not

covered by the Mercedes-Benz LimitedWarranty.

! Vehicles with 4MATIC:Because the ESP® operates automatically,the engine and ignition must be shut off(SmartKey in starter switch position 0 or1 or KEYLESS-GO start/stop button inposition 0 or 1) when the parking brake isbeing tested on a brake test dynamometer.Active braking action through the ESP®

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

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

If your brake system is normally onlysubjected to moderate loads, you shouldoccasionally test the effectiveness of thebrakes by applying above-normal brakingpressure at higher speeds. This will alsoenhance the grip of the brake pads.

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

G Warning!New vehicle brake pads and discs, andreplacement brake pads and discs may takeseveral hundred miles of driving until theyprovide optimum braking efficiency. Until thattime, you may need to use increased brakepedal pressure while braking. Please be awareof this and adjust your driving and brakingaccordingly during this break-in period.Excessive high-demand braking will causecorrespondingly high brake wear. Please beattentive to the brake warning lamp in theinstrument cluster and brake conditionmessages in the multifunction display.Especially for high performance driving, it isimportant to maintain and have the brakesystem checked regularly.

The high-performance brake system isdesigned to operate under the extremely highoperating demands required toaccommodate the performance capabilitiesof the vehicle.The brakes may produce a squeaking-typenoise depending on theRvehicle speedRbrake force appliedRambient conditions, e.g. temperature and

humidityAs with any brake system, the wear ofindividual brake system components such asbrake pads or disks strongly depends on yourdriving style and the conditions under whichyou operate the vehicle. Thus, a driving stylecalling for high-demand braking will causeyour vehicle’s brakes to wear more quickly.

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 an

extended 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.

G Warning!Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You maylose control of the vehicle. Continued driving with a flat tire will cause excessive heat build-upand possibly a fire.

G Warning!Follow recommended tire inflation pressures.Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affecthandling and fuel economy, and are more likely to fail from being overheated.Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wearunevenly, increase stopping distance, and result in sudden deflation (blowout) because they aremore likely to become punctured or damaged by road debris, potholes etc.

If your vehicle has tires of adifferent size than the size indicated on theTire and Loading Information placard or, ifavailable, the tire inflation pressure label, youshould determine the proper tire inflationpressure for 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 tire

maintenance, 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 isilluminated, the system may not be able todetect or signal low tire pressure as intended.TPMS malfunctions may occur for a variety ofreasons, including the installation ofincompatible replacement or alternate tiresor wheels on the vehicle that prevent theTPMS from functioning properly. Alwayscheck the TPMS malfunction telltale afterreplacing one or more tires or wheels on yourvehicle to ensure that the replacement oralternate tires and wheels allow the TPMS tocontinue to function properly.

You might get injured.Battery fluid contains sulfuric acid. Do notallow this fluid to come in contact with eyes,skin or clothing. In case it does, immediatelyflush affected area with water, and seekmedical help if necessary.A battery will also produce hydrogen gas,which is flammable and explosive. Keepflames or sparks away from battery, avoidimproper connection of jumper cables,smoking, etc.Attempting to jump start a frozen battery canresult in it exploding, causing personal injury.Read all instructions before proceeding.

! Vehicles with automatic transmissionand/or 4MATIC:Do not tow-start the vehicle. You couldotherwise seriously damage the automatictransmission which is not covered by theMercedes-Benz Limited Warranty.

! Jump starting should only be performedusing the jump-start terminals located inthe engine compartment.Avoid repeated and lengthy startingattempts.Do not attempt to start the engine using abattery quick-charge unit.If the engine does not run after severalunsuccessful starting attempts, have itchecked at the nearest authorizedMercedes-Benz Center.Excessive unburned fuel generated byrepeated failed starting attempts maydamage the catalytic converter and maypresent a fire risk.

Make sure the jumper cables do not haveloose or missing insulation.Make sure the cable clamps do not touchany other metal part while the other end isstill attached to a battery.

If the battery is discharged, the engine can bestarted with jumper cables and the fullycharged battery of another vehicle or anequivalent starter pack. Observe thefollowing:RAccess to the battery is not possible on all

vehicles. If you cannot access the batteryin your vehicle provide jump start power byan external battery or starter pack.RJump starting should only be performed

when the engine and catalytic converterare cold.RDo not start the engine if the battery is

frozen. Let the battery thaw out first.ROnly jump start from batteries with the

same voltage rating (12 V). Jump startingwith a more powerful battery could damagethe vehicle’s electrical system. Suchdamage will not be covered by theMercedes-Benz Limited Warranty.ROnly use jumper cables with sufficient

cross-section and insulated terminalclamps.RAlways make sure the jumper cables are

not on or near pulleys, fans or other partsthat move when an engine is started orrunning.RShould the battery be drained completely,

let the donating power source charge thevehicle for several minutes beforereattempting the starting process.

Premium unleaded gasoline

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 a

light 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 requirementsOnly 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, andTBA 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.

Flexible Fuel VehiclesC 300 and C 300 Sport68 with automatictransmission are Flexible Fuel Vehicles.Flexible Fuel Vehicles are identified by a labelreading Premium gasoline or E85 only! onthe fuel filler flap.These vehicles are designed to operate onpremium unleaded gasoline or ethanol fuel(E85), or on any mixture of these two. Ethanolfuel (E85) is a mixture of approximately 85%ethanol and 15% unleaded gasoline.

G Warning!Ethanol fuel (E85) and its fumes are highlyflammable, poisonous and burn easily.Ethanol fuel can cause serious injuries ifignited or if you come into contact with it orinhale fumes of it. Avoid inhalation of ethanolfumes and skin contact with ethanol.Extinguish all open flames before refueling.Never smoke or create sparks close toethanol.

Switching fuelsFor best performance and driveability it isrecommended to use either one or the otherfuel. A refueling pattern that alternatesbetween the two different fuels should beavoided if possible.When switching fuels, make sure:RFuel level is below half full.RFuel level is above reserve (fuel tank

reserve warning lamp is not lit).RAmount of added fuel is more than

5 gallons (20 liters).RIgnition is off during refill.RImmediately after refueling engine is

started and operated for at least 5 minutes.These precautions and recommendations aresupposed to prevent any difficulties whenstarting and operating the engine whichotherwise may be experienced before theengine has fully adapted to the different fuel.If in spite of these recommendations theengine does not perform properly, addingmore gasoline (at least 3 gallons [12 liters])to the fuel may improve the engine behavior.

Fuel consumptionE85 fuel contains less energy per gallon thangasoline. To ensure that engine performancewith ethanol fuel is similar to that when usinggasoline, the engine must burn more ethanolfuel. As a result, it is to be expected that the

fuel consumption will increase when usingE85 compared to gasoline operation.

MaintenancePlease inform your authorized Mercedes-Benz Center if you use or have used E85 fuelwhen your vehicle is delivered formaintenance or repairs.

Cold weather performanceIt is possible that starting times willsignificantly increase at temperatures below32‡ (0†). At low temperatures the use of ablock heater is recommended (contact anauthorized Mercedes-Benz Center for furtherinformation). Rough idling may also beexperienced at such temperatures before theengine is fully warmed up.

! E85 fuel is unsuitable for use whenambient temperatures fall below 14‡(-10†).

Hot weather performanceAt ambient temperatures above 95‡ (35†)start times may increase and beaccompanied by a rough idle following thestart.

Gasoline additivesA 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 idle

RKnocking/pingingRMisfireRPower lossIn areas where carbon deposits may beencountered due to lack of availability ofgasoline which contains these additives,Mercedes-Benz recommends the use ofadditives approved by us for use onMercedes-Benz vehicles.Contact an authorized Mercedes-Benz Centeror visit www.mbusa.com (USA only) for alisting of approved product(s). Followdirections on product label.Do not blend other fuel additives with fuel.This only results in unnecessary cost and maybe harmful to the engine operation.

! Damage or malfunction resulting frompoor fuel quality or from blending additionalfuel additives other than those tested andapproved by us for use on Mercedes-Benzvehicles are not covered by the Mercedes-Benz Limited Warranty or by any pre-ownedor Extended Limited warranties.

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 the

pressurized 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.
