Catalytic Converter

Your Mercedes-Benz is equipped withmonolithic type catalytic converters, animportant element in conjunction withthe O2 sensor to achieve substantialcontrol of the pollutants in the exhaustemissions. Keep your vehicle in properoperating condition by following ourrecommended maintenance instructionsas outlined in your MaintenanceBooklet.

Caution!

To prevent damage to the catalyticconverters, use only premium unleadedgasoline in this vehicle.

Any noticeable irregularities in engineoperation should be repaired promptly.Otherwise, excessive unburned fuelmay reach the catalytic convertercausing it to overheat.

Warning!

As with any vehicle, do not idle, parkor operate this vehicle in areas wherecombustible materials such as grass,hay or leaves can come into contactwith the hot exhaust system, as thesematerials could be ignited.

15

Starting and Turning Off the Engine

Before Starting

Engage parking brake and ensureselector lever is in position "P" or "N".Turn key in steering lock to position 2.The charge indicator lamp should comeon.

Cold Engine

Do not depress accelerator. Turn keyin steering lock clockwise to the stop.Release key only when the engine isfiring regularly.

Hot Engine

Do not depress accelerator. Turn key insteering lock clockwise to the stop.If the engine has not fired after approx.4 seconds, depress accelerator andcontinue cranking until the engine isfiring regularly. Release key and backoff accelerator.

At very high coolant temperatures theengine starting time can be shortened ifthe accelerator is depressed slowly atthe beginning of the starting process.

Turning Off

Turn the key in the steering lock toposition 0 to stop the engine.

The key can only be removed with theselector lever in position "P".

If the coolant temperature is very high(e.g. after hard driving on mountainroads), do not shut off the engineimmediately, but allow it to run for 1 -2 minutes at increased idle speed withselector lever in position "P" or "N".

Important!

Due to the installed starter non-repeatfeature, the key must be turnedcompletely to the left before attemptingto start the engine again.

Observe the oil pressure gaugeimmediately after starting the engine.In a very cold engine the oil pressurewill rise slowly after the engine hasstarted. Do not speed up the enginebefore pressure is registered on thepressure gauge. If you do not see thegauge register oil pressure, stop theengine and have it checked.

The charge indicator lamp should goout as soon as the engine has started.

In areas where temperatures frequentlydrop below -4°F (-20°C) werecommend that an engine block heaterbe installed. Your authorizedMercedes-Benz dealer will advise youon this subject.

Driving Instructions

Power Assistance

When the engine is not running, thebrake and steering systems are withoutpower assistance. Under thesecircumstances, a much greater effort isnecessary to stop or steer the vehicle.

Brakes

Caution!

When driving down long and steepgrades, relieve the load on the brakesby shifting into "3", "2" or "B". Thishelps prevent overheating of the brakesand reduces brake pad wear. Do notexceed engine speed limits. Refer toTechnical Data for downshift points.

After hard braking, it is advisable todrive on for some time, rather thanimmediately parking, so the air streamwill cool down the brakes faster.

Warning!

After driving in heavy rain for sometime without applying the brakes orthrough water deep enough to wetbrake components, the first brakingaction may be somewhat reducedand increased pedal pressure may benecessary. Be sure to maintain a safedistance from vehicles in front.

The condition of the parking brakesystem is checked each time the car isin the shop for the requiredmaintenance.

Between maintenance checks, it is agood practice to apply the parkingbrake once or twice while driving atapproximately 30 mph (50 km/h) on adry straight road. Apply parking brakelightly while pulling the release handleout until a slight drag on the wheels isfelt. Keep applying the brake for about10 seconds while pulling the releasehandle out before releasing the parkingbrake completely. This practice willkeep the parking brake at maximumefficiency.

Warning!

The stop lamps will not come onwhen applying the parking brakeonly. Perform the procedure in theprevious paragraph only when theroad is clear of other traffic.

Resting your foot on the brake pedalwill cause excessive and prematurewear of the brake pads.

It can also result in the brakesoverheating thereby significantlyreducing their effectiveness. It maynot be possible to stop the car insufficient time to avoid an accident.

All checks and maintenance work onthe brake system should be carried outby an authorized Mercedes-Benz dealer

17

If the parking brake is released and thebrake warning lamp in the instrumentcluster stays on, the brake fluid level inthe reservoir is too low.

Brake pad wear or a leak in the systemmay be the reason for low brake fluidin the reservoir.

Have the brake system inspected at anauthorized Mercedes-Benz dealerimmediately.

Install only brake pads and brake fluidrecommended by Mercedes-Benz.

Warning!

If other than recommended brakepads are installed, the brakingproperties of the vehicle can bedegraded to an extent that safebraking is substantially impaired.

Tires

Tread wear indicators (TWI) arerequired by law. These indicators arelocated in six places on the treadcircumference and become visible at adepth of approximately 1/16 in(1.5 mm), at which point the tire isconsidered worn and should bereplaced.

The tread wear indicator appears as asolid band across the tread.

Warning!

Do not allow your tires to wear downtoo far. With less than 1/16 in (1.5mm) of tread, the adhesionproperties on a wet road are sharplyreduced.

Depending upon the weather and/orroad surface (conditions), the tiretraction varies widely.

Specified tire pressures must bemaintained. This applies particularly ifthe tires are subjected to high loads(e.g. high speeds, heavy loads, highambient temperatures).

Warning!

Do not allow your tires to wear downtoo far. As tread depth approaches1/16 in (1.5 mm), the adhesionproperties on a wet road are sharplyreduced.

Depending upon the weather and/orroad surface (conditions), the tiretraction varies widely.

18

Aquaplaning

Depending on the depth of the waterlayer on the road, aquaplaning mayoccur, even at low speeds and with newtires. Reduce vehicle speed, avoid trackgrooves in the road and apply brakescautiously in the rain.

Tire Traction

The safe speed on a wet, snow coveredor icy road is always lower than on adry road.

You should pay particular attention tothe condition of the road whenever theoutside temperatures are close to thefreezing point.

Warning!

If ice has formed on the road, tiretraction will be substantiallyreduced. Under such weatherconditions, drive, steer and brakewith extreme caution.

We recommend M + S radial-ply tiresfor the winter season for all four wheelsto insure normal balanced handlingcharacteristics.

On packed snow, they can reduceyour stopping distance as com-paredwith summer tires. Stopping distance,however, is still considerably greaterthan when the road is wet or dry.

Tire Speed Rating

Your vehicle is factory equipped with an"H"-rated tire, which has a speed ratingof 130 mph (210 km/h). An electronicspeed limiter prevents your vehicle fromexceeding the speed resting.

Notwithstanding tire speed rating, localspeed limits should be obeyed, andprudent driving speeds appropriate toprevailing conditions should beemployed.

Warning!

Never operate a vehicle at speedsgreater than the maximum speedrating of the tires with which it isequipped. Exceeding the maximumspeed for which tires are rated canlead to sudden tire failure, causingloss of vehicle control, andresulting in personal injury andpossible death.

Parking

Warning!

To reduce the risk of personal injuryas a result of vehicle movement,before turning off the engine andleaving the vehicle always:

1. Keep right foot on brakepedal.

2. Firmly depress parking brakepedal.

3. Move the selector lever toposition "P".

4. Slowly release brake pedal.5. Turn front wheels towards

the road curb.6. Turn the key to steering

lock position 0 and remove.

Important!

It is advisable to set the parking brakewhenever parking or leaving thevehicle. In addition, move selectorlever to position "P".

When parking on hills, always set theparking brake.

19

Winter Driving Instructions

The most important rule for slippery oricy roads is to drive sensibly and toavoid abrupt acceleration, braking andsteering maneuvers. Do not use thecruise control system under suchconditions.

When the vehicle is in danger ofskidding, move selector lever toposition "N". Try to keep the vehicleunder control by corrective steeringaction.

Road salts and chemicals can adverselyaffect braking efficiency. Increasedpedal force may become necessary toproduce the normal brake effect. Wetherefore recommend depressing thebrake pedal periodically when travelingat length on salt-strewn roads. This canbring road salt impaired brakingefficiency back to normal.A prerequisite is, however, that this isdone without endangering other driverson the road.

If the vehicle is parked after beingdriven on salt treated roads, the brakingefficiency should be tested as soon aspossible after driving is resumed whileobserving the safety rules in theprevious paragraph.

Warning!

If the vehicle becomes stuck in snow,make sure that snow is kept clear ofthe exhaust pipe and from aroundthe vehicle with engine running.Otherwise, deadly carbon monoxide(CO) gases may enter vehicle interiorresulting in unconsciousness anddeath.

To assure sufficient fresh airventilation, open a window slightlyon the side of the car that is out ofthe wind

Passenger Compartment

Warning!

Always fasten items being carried assecurely as possible.

In an accident, during hard brakingor sudden maneuvers, loose itemswill be thrown around inside thevehicle, and cause injury to vehicleoccupants unless the items aresecurely fastened in the vehicle.

Seat Belts and SupplementalRestraint System (SRS)

Your vehicle is equipped with seatbelts for all seats, emergencytensioning retractors for the front seats,as well as airbags and knee bolsters fordriver and front passenger.

Seat Belts

Important!

Laws in most states and all Canadianprovinces require seat belt use.

All states and provinces require use ofchild restraints that comply with U.S.Federal Motor Vehicle Safety Standard213 and Canadian Motor VehicleSafety Standard 213.1.

We strongly recommend their use

Warning!

Never ride in a moving vehicle withthe seat back reclined. Sitting in anexcessively reclined position can bedangerous. You could slide under theseat belt in a collision. If you slideunder it, the belt would apply forceat the abdomen or neck. That couldcause serious or even fatal injuries.The seat back and seat belts providethe best restraint when the wearer isin an upright position and belts areproperly positioned on the body.

Seat Belt Warning System

With the key in steering lock position2, an audible warning sounds for ashort time if the driver's seat belt is notfastened.

Warning!

Failure to wear and properly fastenand position your seat belt greatlyincreases your risk of injuries andtheir likely severity in an accident.You and your passengers shouldalways wear seat belts.

Warning!

If you are ever in an accident, yourinjuries can be considerably moresevere without your seat beltproperly buckled. Without your seatbelt buckled, you can hit the interiorof the vehicle or be ejected from it.You can be seriously injured orkilled.

In the same crash, the possibility forinjury or death is lessened with yourseat belt buckled.

Allow the retractor to completelyrewind the seat belt by guiding thelatch plate (1).Notes:

The rear seat belt buckles can be storedin the space next to the rear armrest (tothe left and right of armrest). The rearcenter seat belt should be latched andstored under the armrest.

For cleaning and care of the seat belts,see Cleaning and Care of the Vehiclein Index.

Operation:

The inertia reel stops the belt fromunwinding during sudden vehicle stopsor when quickly pulling on the belt.The locking function of the reel may bechecked by quickly pulling out the belt.

49

Warning!

USE SEAT BELTS PROPERLY.

• Each occupant should wear theirseat belt at all times, becauseseat belts help reduce thelikelihood of and potentialseverity of injuries in accidents,including rollovers.. "SRS"(driver airbag, passenger airbag),"ETR"(seat belt emergencytensioning retractors), and kneebolsters are designed to enhancethe protection offered toproperly belted occupants incertain frontal impacts whichexceed preset deploymenttresholds.

• Improperly positioned seat beltsdo not provide maximumprotection and may cause seriousinjuries in case of an accident.

• Never wear the shoulder beltunder your arm, against yourneck or off your shoulder. In acrash, your body would move toofar forward.

That would increase the chance ofhead and neck injuries. The beltwould also apply top much forceto the ribs, which could severelyinjure internal organs such asyour liver or spleen

• Position the lap belt as low aspossible on your hips and notacross the abdomen. If the belt ispositioned across your abdomen,it could cause serious injuries in acrash.

• Each seat belt should never beused for more than one person ata time. Do not fasten a seat beltaround a person and objects.

• Belts should not be worn twisted.In a crash, you wouldn't have thefull width of the belt to takeimpact forces. The twisted beltagainst your body could causeinjuries.

• Pregnant women should also use alap-shoulder belt. The lap beltportion should be positioned aslow as possible on the hips toavoid any possible pressure on theabdomen.

USE CHILD RESTRAINTSPROPERLY.

• Infants and small children must beseated in an infant or childrestraint system, which is properlysecured by a lap belt or lap beltportion of a lap-shoulder belt.Children could be endangered inan accident if their child restraintsare not properly secured in thevehicle.

• Rear-facing child restraints mustnot be used in the front seat witha passenger side airbag. Theycould be struck by the airbagwhen it inflates in a crash. If thishappens, a child in the restraintcould be seriously injured.

50

• According to accident statistics,children are safer when properlyrestrained in the rear seatingpositions than in the front seatingpositions.

• Children too big for child restraintsystems should ride in rear seatsusing regular seat belts. Positionshoulder belt across chest andshoulder, not face or neck. Abooster seat may be necessary toachieve proper belt positioning.

• Adjust the front passenger seat asfar as possible rearward from thedashboard when a child restraintis installed.

Supplemental Restraint System(SRS)

The SRS uses two crash severity levels(thresholds) to activate either the ETRor airbag or both. Activation dependson exceeding the thresholds andfastening of the seat belt.

Seat belt fastened

• first threshold exceeded:ETR activates

• second threshold exceeded:airbag also activates

Seat belt not fastened

• first threshold exceeded:airbag activates, but not ETR

Driver and front passenger systemsoperate independently from each other.

Emergency Tensioning Retractor(ETR)

The seat belts for the front seats areequipped with emergency tensioningretractors. These tensioning retractorsare located in each belt's inertia reeland become operationally ready withthe key in steering lock position 1 or 2.

The emergency tensioning retractorsare designed to activate only when theseat belts are fastened during frontaland front-angled impacts exceeding thefirst threshold of the SRS. They re-move slack from the belts in such away that the seat belts fit more snuglyagainst the body restricting its forwardmovement as much as possible.

In cases of other frontal impacts,roll-overs, certain side impacts, rearcollisions, or other accidents withoutfrontal forces, the emergencytensioning retractors will not beactivated. The driver and passengerswill then be protected by the fastenedseat belts and inertia reel in the usualmanner.

For seat belt and emergency ten-sioning retractor safety guidelines seeSafety Guidelines in Index.

51

Airbags

The most effective occupant restraintsystem yet developed for use inproduction vehicles is the seat belt. Insome cases, however, the protectiveeffect of a seat belt can be furtherenhanced by an airbag.

The driver airbag (1) is located in thesteering wheel hub. The passengerairbag (2) is located in the dashboardahead of the passenger. In conjunctionwith wearing the seat belts withemergency tensioning retractors (4),they provide increased protection forthe driver and passenger in certainmajor frontal and front angled impacts.

The operational readiness of the airbagsystem is verified by the indicator lamp"SRS" (3) in the instrument cluster. Ifno fault is detected, the lamp will goout after approximately 4 seconds; afterthe lamp goes out, the system continuesto monitor the components andcircuitry of the airbag system and willindicate a malfunction by coming onagain

52

The following system components aremonitored or undergo a self-check:crash-sensor, airbag ignition circuits,driver and passenger seat belt buckles.Initially, when the key is turned fromsteering lock position 0 to positions 1or 2, malfunctions in the crash-sensorare detected and indicated (the "SRS"indicator lamp stays on longer than 4seconds).

In the operational mode, after theindicator lamp has gone out followingthe initial check, interruptions and shortcircuits in the airbag ignition circuitand in the driver and passenger seatbelt buckle harnesses, and low voltagein the entire system are detected andindicated.

In the event a malfunction of the "SRS"is indicated as outlined above, the"SRS" may not be operational. Westrongly recommend that you visit anauthorized Mercedes-Benz dealerimmediately to have the systemchecked; otherwise the "SRS" may notbe activated when needed.

Important!

The airbags are designed to activateonly in certain frontal and front-angled impacts (within the shadedarea shown in the illustration onpage 48). Only during these types ofimpacts will they provide theirsupplemental protection. The driverand passenger should always wearthe seat belts, otherwise it is notpossible for the airbags to providetheir intended supplementalprotection.

In cases of other frontal impacts,roll-overs, certain side impacts, rearcollisions, or other accidents withoutsufficient frontal forces, the airbagwill not be activated. The driver andpassengers will then be protected bythe fastened seat belts.

We caution you not to rely on thepresence of an airbag in order toavoid wearing your seat belt.

53

Important!

The "SRS" is designed to reduce thepotential of injury in certain frontaland front-angled impacts which maycause injuries, however, no systemavailable today can totally eliminateinjuries and fatalities.

The activation of the "SRS"temporarily releases a small amountof dust from the air-bags. This dust,however, is neither injurious to yourhealth, nor does it indicate a fire in thevehicle.

The service life of the airbags extendsto the date indicated on the labellocated on the driver-side door latchpost. To provide continued reliabilityafter that date, they should beinspected by an authorized Mercedes-Benz dealer at that time and replacedwhen necessary.

Warning!

It is very important for your safetyto always be in a properly seatedposition and to wear your seat belt.

For maximum protection in theevent of a collision always be innormal seated position with yourback against the seat back. Fastenyour seat belt and ensure that it isproperly positioned on the body.

Since the airbag inflates withconsiderable speed and force, aproper seating position will keep youin a safe distance from the airbag:

• Sit properly belted in an uprightposition with your back againstthe seat back.

• Adjust the driver seat as faras possible rearward, stillpermitting proper operationof vehicle controls.

• Do not lean with your head orchest close to the steering wheelor dashboard.

• Adjust the passenger seat as faras possible rearward from thedashboard.

• Infants and small children shouldonly be seated in a rear seat andbe properly secured in a childrestraint system.

• Rear-facing child restraints mustnot be used in a front seat with apassenger side airbag.

Failure to follow these instructionscan result in severe injuries to you orother occupants.

54

Safety Guidelines for the Seat Belt,Emergency Tensioning Retractorand Airbag

Warning!

• Damaged belts or belts that werehighly stressed in an accident mustbe replaced and their anchoringpoints must also be checked. Useonly belts installed or supplied byan authorized Mercedes-Benzdealer.

• Do not pass belts over sharp edges.

• Do not make any modification thatcould change the effectiveness ofthe belts.

• The "SRS" is designed to functionon a one-time-only basis. Anairbag or emergency tensioningretractor (ETR) that wasactivated must be replaced.

• No modifications of any kind maybe made to any components orwiring of the "SRS". Thisincludes the installation ofadditional trim material, badgesetc. over the steering wheel hub orfront passenger airbag cover andinstallation of additionalelectrical/electronic equipment onor near "SRS" components andwiring.

• Several airbag system componentsat the steering wheel get hot afterthe airbag has inflated. Don't tryto touch them.

• Improper work on the system,including incorrect installationand removal, can lead to possibleinjury through an uncontrolledactivation of the "SRS".

• In addition, through improperwork there is the risk ofrendering the "SRS" inoperative.Work on the "SRS" musttherefore only be performed byan authorized Mercedes-Benzdealer.

• When scrapping the airbagunit or emergency tensioningretractor, it is mandatory tofollow our safety instructions.These instructions are availableat your authorized Mercedes-Benz dealer.

When you sell the vehicle we stronglyurge you to give notice to thesubsequent owner that it is equippedwith an "SRS" by alerting him to theapplicable section in the Owner'sManual.

55

Infant and Child RestraintSystems

We recommend that all infants andchildren be restrained at all times whilethe vehicle is in motion.

Important!

The use of infant or child restraints isrequired by law in all 50 states and allCanadian provinces.

Infants and small children should beseated in an infant or child restraintsystem, which is properly secured by alap belt or lap belt portion of a lap-shoulder belt, and that complies withU.S. Federal Motor Vehicle SafetyStandard 213 and Canadian MotorVehicle Safety Standard 213.1. A state-ment by the child restraint manu-facturer of compliance with thisstandard can be found on theinstruction label on the restraint and inthe instruction manual provided withthe restraint.

When using any infant or child restraintsystem, be sure to carefully read andfollow all manufacturer's instructionsfor installation and use.

Warning!

According to accident statistics,children are safer when properlyrestrained in the rear seating positionsthan in the front seating positions.

Rear-facing child restraints must notbe used in the front passenger seat.They could be struck by the airbagwhen it inflates in a crash. If thishappens, a child in the restraint couldbe seriously injured.

Infants and small children shouldnever be held on the lap while thevehicle is in motion. During anaccident they would be almostimpossible to hold, and could becrushed between the adult and thedashboard.

Infants and small children shouldnever share a seat belt with anotheroccupant. During an accident, theycould be crushed between theoccupant and seat belt.

Children too big for child restraintsystems should ride in rear seatsusing regular seat belts. Positionshoulder belt across chest andshoulder, not face or neck. A boosterseat may be necessary to achieveproper belt positioning.

When the child restraint is not inuse, remove it from the car or secureit with the seat belt to prevent thechild restraint from becoming aprojectile in the event of an accident.

U.S.A. Models only:

Since 1986 all U.S. child restraintscomply with U.S. regulations withoutthe use of a tether strap.

Canada Models only:

This vehicle can be equipped withtether anchorages for a top tether strap.Consult your authorized Mercedes-Benz dealer for installation of theseanchorages.

In compliance with Canadian MotorVehicle Safety Standard 210.1, childrestraint tether anchorage hardware isattached to the tool kit located in thetrunk.

Driving Off

Test the brakes briefly after driving off.Perform this procedure only when theroad is clear of other traffic.

Warm up the engine smoothly. Do notplace full load on the engine until theoperating temperature has beenreached.

Warning!

Keep driver's foot area clear at alltimes. Objects stored in this areamay impair pedal movement.

75

Automatic Transmission

The automatic transmission selectsindividual gears automatically,dependent upon

• Selector lever position• Accelerator position• Vehicle speed

Important!

When parking the car and beforeworking on the vehicle with the enginerunning, firmly depress the parkingbrake pedal and shift the selector leverinto "P".

Driving

The selector lever is automaticallylocked while in position "P". To movethe selector lever out of position "P",the service brake pedal must be firmlydepressed before the shift lock willrelease.

Shift selector lever to the desired drivingposition only when the engine is idlingand the service brake is applied. Do notrelease

the brake until ready to drive. Thevehicle may otherwise start creepingwhen the selector lever is in drive orreverse position.

Warning!

It is dangerous to shift the selectorlever out of "P" or "N" if the enginespeed is higher than idle speed. Ifyour foot is not on the brake pedal,the car could accelerate quicklyforward or in reverse. You could losecontrol of the car and hit someone orsomething. Only shift info gear whenthe engine is idling normally andwhen your right foot is firmly on thebrake pedal.

Important!

After selecting any driving positionfrom "N" or "P", wait a moment toallow the gear to fully engage beforeaccelerating, especially when theengine is cold.

Accelerator position

Partial throttle = early up shifting= normal acceleration

Full throttle = later up shifting =rapid acceleration

Kick down (depressing the acceleratorbeyond full throttle) = downshifting tonext lowest gear = maximumacceleration. Once the desired speed isattained, ease up on the accelerator -the transmission shifts up again

76

Selector Lever Positions S 320

The automatic gear shifting processcan be adapted to specific operatingconditions using the selector lever.

P Parking lock.The parking lock is an additionalsafeguard to the parking brakewhen parking the vehicle. Engageonly with the car stopped.

Note:The key can be removed from thesteering lock only with the selectorlever in position "P".

With the key removed, the selectorlever is locked in position "P".

R Reverse gear.Shift to reverse gear only with thecar stopped.

N Neutral.No power is transmitted from theengine to the rear axle. When thebrakes are released, the vehicle canbe moved freely (pushed or towed).Do not engage "N" while drivingexcept to coast when the vehicle isin danger of skidding (e.g. on icyroads, see Winter DrivingInstructions in Index).

Important!Coasting the vehicle, or driving forany other reason with selector leverin "N", can result in transmissiondamage that is not covered by theMercedes-Benz Limited Warranty.

D The transmission automaticallyupshifts to 5th gear. Position "D"provides optimum drivingcharacteristics under all normaloperating conditions.

4 Upshift to 4th gear only. Suitablefor performance driving.

3 Upshift to 3rd gear only. Suitablefor moderately steep hills. Sincethe transmission does not shifthigher than 3rd gear, this gearselection will allow use of theengine's braking power downhill.

2 Upshift to 2nd gear only. Fordriving in mountainous regions orunder extreme operatingconditions. This gear selectionwill allow use of the engine'sbraking power when descendingsteep grades.

Important!

With selector lever in position "D", "4"or "3", upshifting from 1st to 2nd to3rd gear is delayed depending onvehicle speed and engine temperature.This allows the catalytic converter toheat up more quickly to operatingtemperatures. During the brief warm-up period this delayed upshift andincreased engine noise might beperceived as a malfunction. However,neither the engine nor transmission arenegatively affected by this mode ofoperation.

77

The delayed up shift is effective withvehicle speeds below 31 mph (50km/h) at partial throttle and enginetemperatures below 95°F (35°C).

Do not exceed the vehicle speedlimits for individual gear selections.Overrevving the engine when selectorlever is moved to a lower drivingrange could result in serious damageto the engine that is not covered bythe Mercedes-Benz Limited Warranty.Refer to Technical Data for downshiftpoints.

Warning!

On slippery road surfaces, neverdownshift in order to obtain brakingaction. This could result in rearwheel slip and reduced vehiclecontrol. Your vehicle's ABS will notprevent this type of loss of controlThis applies particularly for position"B".

To prevent the engine from laboring atlow RPMs, do not allow the enginespeed to drop too low on uphillgradients.

Depending on the degree of the incline,shift selector lever to a lower gear earlyenough to maintain engine RPM withinthe best torque range.

Maneuvering

To maneuver in tight areas, e.g. whenpulling into parking space, control thecar speed by gradually releasing thebrakes. Accelerate gently and neverabruptly step on the accelerator.

To rock a car out of soft ground (mudor snow), alternately shift from forwardto reverse, while applying slight partialthrottle.

Rocking a car free in this manner maycause the ABS warning lamp to comeon. Turn off and restart the engine toclear the malfunction indication.

Stopping

For brief stops, e.g. at traffic lights,leave the transmission in gear and holdvehicle with the service brake.

For longer stops with the engine idling,shift into "N" or "P".

When stopping the car on an uphillincline, do not hold it with theaccelerator, use the brake. This avoidsunnecessary transmission heat build up.

Warning!

Getting out of your car with theselector lever not fully engaged inposition "P" is dangerous. Whenparked on an incline, position "P"alone may not prevent your vehiclefrom moving, possibly hitting peopleor objects.

Always set the parking brake inaddition to shifting to position "P".

2 Upshift to 2nd gear only. Fordriving in mountainous regions.Since the transmission does notshift higher than 2nd gear, thisgear selection will allow use of theengine's braking power downhill.

B In this position, the engine'sbraking effect is utilized byshifting into 1st gear. Use thisposition while descending verysteep or lengthy downgrades andonly at speeds below 40 mph (60km/h).

Important!

With selector lever in position "D" or"3", upshifting from 2nd to 3rd gear isdelayed depending on vehicle speedand engine temperature. This allows thecatalytic converter to heat up morequickly to operating temperatures.During the brief warm-up period thisdelayed upshift and increased enginenoise might be perceived as amalfunction.

Rear Fender Indicators

When the reverse gear is selected, therear fender indicators will extendupward from the rear corners of thefenders.

The rear fender indicators retractdelayed when shifting out of reverse.They retract immediately when turningkey in steering lock to position 0.

Note:

Before shifting into reverse gear,ensure that the rear fender indicatorscan extend freely. Cruise Control

Any given speed above approximately25 mph (40 km/h) can be maintainedwith the cruise control by operating thelever.

1 Accelerate and set:Lift lever briefly to set speed. Holdlever up to accelerate.

2 Decelerate and set:Depress lever briefly to set speed.

Hold lever down to decelerate.

Normally the vehicle is accelerated tothe desired speed with the accelerator.

Speed is set by briefly pushing thelever to position 1 or 2. The acceleratorcan be released.

The speed can be increased (e.g. forpassing) by using the accelerator. Assoon as the accelerator is released, thepreviously set speed will be resumedautomatically.

If a set speed is to be increased ordecreased slightly, e.g. to adapt to thetraffic flow, hold lever in position 1 or2 until the desired speed is reached, orbriefly tip the control lever in theappropriate direction for increases ordecreases in 0.6 mph (1 km/h)increments. When the lever is released,the newly set speed remains.

81

3 Canceling

To cancel the cruise control, brieflypush lever to position 3.

When you step on the brake or thevehicle speed drops below approx.25 mph (40 km/h), for examplewhen driving upgrade, the cruisecontrol will be canceled.

If the cruise control cancels by itselfand remains inoperative until theengine is restarted, have the systemchecked at your authorizedMercedes-Benz dealer as soon aspossible.

4 Resume

If the lever is briefly pushed toposition 4 when driving at a speedexceeding approx. 25 mph (40 km/h),the vehicle resumes the speed whichwas set prior to the cancellation of thecruise control. The last memorizedspeed is canceled when the key in thesteering lock 's turned to position1 or 0

Note:

If the engine does not brake the vehiclesufficiently while driving on adowngrade, the speed you set on thecruise control may be exceeded andyou may have to step on the brakepedal to slow down. As soon as thegrade eases, the cruise controlled speedwill again -be maintained as long as thebrakes were not previously applied, orthe lever may be used to resume thepreviously set speed if the brakes wereapplied.

Caution!

When driving with the cruise control,the transmission selector lever must notbe shifted to position "N" as otherwisethe engine will overrev.

Warning!

Only use the cruise control if thetraffic and weather conditions makeit advisable to travel at a steadyspeed.

• The use of cruise control can bedangerous on winding roads or inheavy traffic because conditionsdo not allow safe driving at asteady speed.

• The use of cruise control can bedangerous on slippery roads.Rapid changes in tire adhesioncan result in wheel spin and lossof control.

The "Resume" function should onlybe operated if the driver is fullyaware of the previously set speedand wishes to resume this particularpreset speed.

82

Charge Indicator Lamp

Should the charge indicator lamp fail tocome on prior to starting when the keyis in steering lock position 2 or shouldit fail to go out after starting or comewhile the engine is running, thisindicates a fault which must be repairedat an authorized Mercedes-Benz dealerimmediately.

If the charge indicator lamp comes onwhile the engine is running, this mayindicate that the poly-V-belt has broken.Should this condition occur, the poly-V-belt must be replaced before continuingto operate the vehicle. Otherwise, theengine will overheat due to aninoperative water pump which mayresult in damage to the engine.

Do not continue to drive the vehiclewith the charge indicator lampilluminated. Doing so could result inengine damage that is not covered bythe Mercedes-Benz Limited Warranty.

Oil Pressure Gauge with OilPressure Warning Lamp

With the key in steering lock position2, the oil pressure warning lamp comeson and should go out when the engineis running.

The oil pressure at idle speed maydrop if the engine is at operatingtemperature. This will not jeopardizethe engine's operational reliability.

Pressure must, however, riseimmediately upon acceleration.

Note:

If the oil pressure warning lamp doesnot go out after starting the engine orcomes on while driving and the oilpressure gauge needle drops to "0",then damage to the engine may occurwith continued operation. Turn offengine immediately and contact anauthorized Mercedes-Benz dealer. Donot operate the car until the conditionis repaired.

There is no need for concern should theoil pressure warning lamp light upbriefly, (for example, in sharp turns orhard braking) provided the lamp goesout immediately. We recommend youto drive to the nearest service stationwhere the engine oil should be toppedto the "full" mark on the dipstick withan approved oil.

Engine Oil Pressure Gauge

The oil pressure at idle speed maydrop if the engine is at operatingtemperature. This will not jeopardizethe engine's operational reliability.Pressure must, however, riseimmediately upon acceleration.

Note:

If the oil pressure gauge needle dropsto "0" with the engine running, thendamage to the engine may occur withcontinued operation. Turn off engineimmediately and contact an authorizedMercedes-Benz dealer. Do not operatethe car until the condition is repaired.

83

Low Engine Oil Level WarningLamp

With the key in steering lock position2, the oil level warning lamp comes onand should go out when the engine isrunning.

If the warning lamp comes on with theengine running and at operatingtemperature, the engine oil level hasdropped to approximately the minimummark on the dipstick.

When this occurs, the warning lampwill first come on intermittently andthen stay on if the oil level dropsfurther.

If no oil leaks are noted and there is noloss in engine oil pressure, continue todrive to the nearest service stationwhere the engine oil should be toppedto the "full" mark on the dipstick withan approved oil.

The low engine oil level warning lightshould not be ignored. Extendeddriving with the light illuminatedcould result in engine damage that isnot covered by the Mercedes-BenzLimited Warranty.

In addition to the warning lamp, theengine oil level should be periodicallychecked with the dipstick, for exampleduring a fuel stop, or before a long trip.See Index.

Tachometer

Red marking on tachometer:Excessive engine speed.Avoid this engine speed, as it mayresult in engine damage that is notcovered by the Mercedes-BenzLimited Warranty.

For engine protection, the fuel supplyis interrupted if the engine is operatedwithin the red marking.

Engine Oil Consumption

Engine oil consumption checks shouldonly be made after the break-in period.During the break-in period, higher oilconsumption may be noticed and isnormal. Frequent driving at highengine speeds results in increasedconsumption.

Fuel Consumption Gauge

While driving, current fuelconsumption is indicated in miles pergallon (mpg), or in Canada liters per100 kilometers (1/100 km).

With the engine switched off, theneedle reads "0".

Due to system design, maximumconsumption is indicated at engine idlespeed.

84

Fuel Reserve Warning Lamp

With the key in steering lock position2, the fuel reserve warning lamps comeon and should go out when the engineis running.

If the warning lamps do not go outafter starting the engine or if they comeon while driving, it indicates that thefuel level is down to the reservequantity of approx. 3.3 gal (12.5 liters).

Outside Temperature Indicator

The temperature sensor is located inthe front bumper area. Due to itslocation, the sensor can be affected byroad or engine heat during idling orslow driving. This means that theaccuracy of the displayed temperaturecan only be verified by comparison to athermometer placed next to the sensor,not by comparison to external displays(e.g. bank signs etc.).

Adaptation to ambient temperaturetakes place in steps and depends on theprevailing driving conditions (stop-and-go or moderate, constant driving)and amount of temperature change.

Warning!

The outside temperature indicator isnot designed to serve as an Ice-Warning Device and is therefore un-suitable for that purpose. Indicatedtemperatures just above the freezingpoint do not guarantee that the roadsurface is free of ice.

Coolant Temperature Gauge

If the antifreeze mixture is effective to-22°F (-30°C), the boiling point of thecoolant in the pressurized coolingsystem of your vehicle is approx.266°F (130°C).

During severe operating conditionsand stop-and-go city traffic, thecoolant temperature may rise close tothe red marking.

The engine should not be operatedwith the coolant temperature in the redzone. Doing so may cause seriousengine damage which is not coveredby the Mercedes-Benz LimitedWarranty.

Warning!

• Driving when your engine is badlyoverheated can cause some fluidswhich may have leaked into theengine compartment to catch fire.You could be seriously burned.Turn off the engine and get out ofthe car until it cools down.

• Steam from an overheated enginecan cause serious burns and canoccur just by opening the enginehood. Stay away from the engineif you see or hear steam comingfrom it. Turn off the engine anddo not stand near the car until itcools down.

If the warning lamp does not go outafter starting the engine, or if it comeson while driving, then the coolant levelhas dropped below the required level.If no leaks are noticeable and theengine temperature does not increase,continue to drive to the nearest servicestation and have coolant added to thecoolant system. See Index.

The low engine coolant level warninglight should not be ignored. Extendeddriving with the light illuminated maycause serious engine damage notcovered by the Mercedes-BenzLimited Warranty.

In cases of major or frequent minorcoolant loss, have the cooling systemchecked at your authorized Mercedes-Benz dealer as soon as possible.

Note:

Do not drive without coolant in thecooling system. The engine willoverheat causing major engine damage.

Monitor the coolant temperature gaugewhile driving.

Warning!

Do not spill antifreeze on hot engineparts. Antifreeze contains ethyleneglycol which may burn if it comesinto contact with hot engine parts.You can be seriously burned.

Exterior Lamp Failure IndicatorLamp

With the key in steering lock position2, a dim indicator lamp comes on, andgoes out when the engine is running.With the key in steering lock position 2or with the engine running, a brightillumination of this lamp indicates anexterior lamp failure.

If an exterior lamp fails, the indicatorlamp will come on only when that lampis switched on.

If a brake or turn signal lamp fails, thelamp failure indicator will come onwhen applying the brake or actuatingthe turn signal and stay on until theengine is turned off.

Note:

The indicator lamp will also come on ifan incorrect bulb is installed.

If additional lighting equipment isinstalled (e.g. auxiliary headlamps etc.)be certain to connect into the fusebefore the failure indicator monitoringunit in order to avoid damaging thesystem.

Seat Belt Warning Lamp

With the key in steering lock position2, the warning lamp comes on and anaudible warning sounds for a short timeif the driver's seat belt is not fastened.

After starting the engine, the warninglamp blinks for a brief period to remindthe driver and passengers to fasten seatbelts before driving off.

Brake Pad Wear Indicator Lamp

The brake pad wear indicator lamp inthe instrument cluster comes on whenthe key in the steering lock is turned toposition 2 and goes out when theengine is running.

If the indicator lamp lights up duringbraking, this indicates that the frontwheel brake pads are worn down.

Have the brake system checked at yourauthorized Mercedes-Benz dealer assoon as possible.

87

Brake Warning Lamp

The brake warning lamp will come onwith the key in steering lock position 2and should go out when the engine isrunning.

The brake warning lamp will come on:

• when there is insufficient brakefluid in the reservoir (enginerunning and parking brakereleased)

• when the parking brake is set(engine running).

Warning!

Driving with the brake warninglamp on can result in an accident.Have your brake system checkedimmediately if the brake warninglamp stays on. Don't add brake fluidbefore checking the brake system.Overfilling the brake fluid reservoircan result in spilling brake fluid onhot engine parts and the brake fluidcatching fire. You can be seriouslyburned.

When the minimum mark on thereservoir is reached, have the brakesystem checked for brake pad thicknessand leaks.

To test the brake warning lamp, turnkey in steering lock to position 2. Thebrake warning lamp comes on, andshould go out when the engine isrunning.

88

Antilock Brake System (ABS)

The ABS prevents the wheels fromlocking up above a vehicle speed ofapproximately 2 mph (3 km/h)independent of road surface conditions.It is necessary, however, that thevehicle speed reaches at least 5 mph(8 km/h) before commencing to brake.

At the instant one of the wheels isabout to lock up, a slight pulsation canbe felt in the brake pedal, indicatingthat the ABS is in the regulating mode.

On slippery road surfaces, the ABSwill respond even with only slightbrake pedal pressure. The pulsatingbrake pedal can be an indication ofhazardous road conditions andfunctions as a reminder to take extracare while driving.

The ABS warning lamp in theinstrument cluster comes on with thekey in steering lock position 2 andshould go out when the engine isrunning.

If the charging voltage falls below 10volts, the warning lamp comes on andthe ABS is switched off. When thevoltage is above this value again, thewarning lamp should go out and theABS will be operational.

If the ABS warning lamp does not goout or comes on while driving, itindicates that the ABS has detected amalfunction and has switched off. Inthis case, the brake system functions inthe usual manner, but without antilockassistance.

Have the system checked at yourauthorized Mercedes-Benz dealer assoon as possible.

Warning!

Even the ABS cannot prevent thenatural laws of physics from actingon the vehicle. The ABS cannotprevent accidents, including thoseresulting from excessive speed inturns, following another vehicle tooclosely, or aquaplaning. Only a safe,attentive, and skillful driver canprevent accidents. The capabilities ofan ABS equipped car must never beexploited in a reckless or dangerousmanner which could jeopardize theuser's safety or the safety of others.

Note:

To alert following vehicles to slipperyroad conditions you discover, operateyour hazard warning flashers asappropriate.

89

Acceleration Slip Control (ASR)

The acceleration slip control will engageat all vehicle speeds, if one or both drivewheels begin to lose traction and spin.While engaged, the yellow functionindicator in the speedometer lights up.

With the acceleration slip control engaged,the brake is applied to the spinning drivewheel until it regains sufficient traction.If both drive wheels lose traction and spin,the brake is applied to both drive wheelsand simultaneously, engine torque islimited.

As traction on the road surface increases,the allowable engine torque also increasesagain and the brake is no longer applied todrive wheels.

Caution!

If the vehicle is towed with the frontaxle raised (see Towing the vehicle inIndex), the key must not be insteering lock position 2. Otherwise,the acceleration slip control willimmediately be engaged and willapply the rear wheel brakes.

Notes:

With the key in steering lock position2, the yellow function indicator lampand the yellow ASR warning lamp inthe instrument cluster come on. Theymust go out when the engine isrunning.

If the ASR warning lamp comeson with the engine running, amalfunction has been detected.Pressing the accelerator pedal willrequire greater effort. Only partialengine output is available.

Have the acceleration slip controlchecked at your authorized Mercedes-Benz dealer as soon as possible.

Driving the vehicle with varied sizetires will cause the wheels to rotate atdifferent speeds, therefore theacceleration slip control will activate(yellow ASR function indicator lamp ininstrument cluster comes on). For thisreason, all wheels, including the sparewheel, must have the same tire size.

When testing the parking brake on abrake test dynamometer, the key mustnot be in steering lock position 2.Otherwise, the acceleration slip controlwill immediately be engaged and willapply the rear wheel brakes.

In winter operation, the maximumeffectiveness of the acceleration slipcontrol is only achieved withMercedes-Benz recommended M + Sradial-ply tires.

The brake pad wear warning lampindicates brake pad wear for the frontas well as the rear brakes.

Traveling Abroad

Abroad, there is a widely-spreadMercedes-Benz service network at yourdisposal. If you plan to travel into areaswhich are not listed in the index ofyour dealer directory, you shouldrequest pertinent information from yourauthorized Mercedes-Benz dealer.

Winter Driving

Have your car winterized at yourauthorized Mercedes-Benz dealerbefore the onset of winter.

• Change the engine oil if the enginecontains an oil which is notapproved for winter operation. Forviscosity (SAE class) and fillingquantity, see Capacities: Fuels,Coolants, Lubricants etc. in Index.

• Check engine coolant anticorrosion/antifreeze concentration.

• Additive for the windshield washerand headlamp cleaning system: AddMB Concentrate "S" to a premixedwindshield washer solvent/antifreezewhich is formulated for belowfreezing temperatures (see Index).

• Test battery: Battery capacity dropswith decreasing ambienttemperature. A well charged batteryensures that the engine can always bestarted, even at low ambienttemperatures.

• Tires: We recommend M + S radialtires on all four wheels for thewinter season. Observe permissiblemaximum speed for M + S radialtires and the legal speed limit.

Note:

In winter operation, the maximumeffectiveness of the acceleration slipcontrol is only achieved with M + Sradial tires.

Snow Chains

Use only snow chains that are testedand recommended by Mercedes-Benz.Your authorized Mercedes-Benz dealerwill be glad to advise you on thissubject.

Chains should only be used on the rearwheels. Follow the manufacturer'smounting instructions.

Snow chains should only be driven onsnow covered roads at speeds not toexceed 30 mph (50 km/h). Removechains as soon as possible when drivingon roads without snow.

Hood

To open:To unlock the hood, pull release lever(1) under the driver's side of theinstrument panel. At the same timehandle (2) will extend out of theradiator grill (it may be necessary to liftthe hood up slightly).

Caution!

To avoid damage to the windshieldwipers or hood, open the hood onlywith wipers in the parked position.

Pull handle (2) completely out ofradiator grill and open hood (do notpull up on handle).

To close:Lower hood and let it drop into lockfrom a height of approx. 1 ft (30 cm),assisting with flat hands placed only onedges of hood (3).

To avoid hood damage, if hood is notfully closed, repeat closing procedure.

Warning!

To help prevent personal injury; stayclear of moving parts when the hood isopen and the engine is running. Besure the hood is properly closedbefore driving.

The engine is equipped with atransistorized ignition system. Becauseof the high voltage it is dangerous totouch any components (ignition coil,distributor, spark plug sockets,ignition cables, diagnostic socket) ofthe ignition system

• with the engine running,

• while starting the engine,

• if the ignition is "on" and theengine is turned manually.

We recommend that you do not openthe hood, if you see flames or smokecoming from the engine compartment.

97

Checking Coolant Level

To check the coolant level, the vehiclemust be parked on level ground and theengine stopped.

Check coolant level only when coolantis cold.

The coolant should reach the markinginside the filler neck

Warning!

• Use extreme caution when openingthe hood if there are any signs ofsteam or coolant leaking from thecooling system.

• Do not remove pressure cap oncoolant reservoir if enginetemperature is above 194 °F(90 °C). Allow engine to cool-down before removing cap. Thecoolant reservoir contains hotfluid and is under pressure.

• Using a rag, turn cap to firstnotch to relieve excess pressure. Ifopened immediately, scalding hotfluid and steam will be blown outunder pressure, possibly causingpersonal injury.

• Do not spill antifreeze on hotengine parts. Antifreeze containsethylene glycol which may burn ifit comes into contact with hotengine parts. You can be seriouslyburned

Adding Coolant

If coolant has to be added, a 50/50mixture of water and MB anticorrosion/antifreeze should be added.

Checking AutomaticTransmission Fluid Level

Dipstick locking lever

1 Break seal2 Release3 Engage

Regular automatic transmission fluidlevel checks are not required. For thisreason the dipstick opening is sealed.

When noticing fluid loss or gear shiftingmalfunctions, we recommend to haveyour authorized Mercedes-Benz dealercheck the transmission fluid level.

The transmission fluid level should onlybe checked with the engine idling,parking brake engaged and selector leverin position "P". The vehicle must beparked on level ground.

Prior to the check, allow engine to idlefor approx. 1 to 2 minutes.

To pull dipstick from tube, break seal bymoving plastic pin (1) sideways. Thenopen cap by releasing locking lever (2).

Measure fluid level with the dipstickcompletely inserted and the locking leverreleased (2).

Extreme cleanliness must be observed!To wipe the dipstick, use a clean, lint-free cloth.

To fill the transmission with fluid, pour itthrough a fine-mesh filter into thedipstick opening. Even the slightestimpurity may cause operational troubles.

The level of the transmission fluid isdependent upon its temperature. Twosets of maximum and minimum fluidlevel marks on the dipstick areapplicable references only if thetransmission fluid has either reachedits normal operating temperature of176° F (80°C), or its temperature is86°F (30°C).

Important!

The fluid level must not exceed thedipstick maximum mark. Drain orsiphon excess fluid, if required.Then push dipstick all the way in andswing locking lever downward (3).

Note:

Damage to transmission caused bycontamination of transmission fluid oroverfilling of transmission may resultin serious transmission damage whichis not covered by the Mercedes-BenzLimited Warranty.

Wheels

Replace rims or tires with the samedesignation, manufacturer and type asshown on the original part. See yourauthorized Mercedes-Benz dealer forfurther information.

Warning!

Do not mix different tire constructiontypes (i.e. radial, bias, and bias-belted)on your car because handling may beadversely affected and may result inloss of control.

See your authorized Mercedes-Benzdealer for information on tested andrecommended rims and tires forsummer and winter operation. Theycan also offer advice concerning tireservice and purchase.

Tire Replacement

Front tires should be replaced in sets.Furthermore - in the event of tirereplacement - the spare wheel, ifpossible, should be used on the rearaxle. Rims and tires must be of thesame size and type. For dimensions,see "Technical Data".

We recommend that you break in newtires for approx. 60 miles (100 km) atmoderate speed. It is imperative that thewheel mounting bolts be retightenedafter approx. 60-300 miles (100-500km).

On new vehicles retightening is carriedout during the 1st inspection.Retightening is also necessarywhenever wheels are fitted, e.g. whenthe spare wheel is used for the firsttime or when a set of wheels with M +S tires is installed.

Tightening torque: 110 ft.lb. (150 Nm).For rim and tire specifications, refer to"Technical Data".

Warning!

Worn, old tires can cause accidents.If the tire tread is badly worn, or ifthe tires have sustained damage,replace them.

When replacing rims, use onlygenuine Mercedes-Benz wheel bolts(identified by Mercedes star)specified for the particular rim type.Failure to do so can result in the boltsloosening and possibly an accident.

Rotating Wheels

The wheels can be rotated according tothe degree of tire wear while retainingthe same direction of travel. Rotating,however, should be carried out at thescheduled maintenance intervals,before the characteristic tire wearpattern (shoulder wear on front wheelsand tread center wear on rear wheels)becomes visible, as otherwise thedriving properties deteriorate.

Important!

Unidirectional snow tires must alwaysbe mounted with arrow on tire sidewallpointing in direction of vehicle forwardmovement.

Note:

Thoroughly clean the inner side ofthe wheels any time you rotate thewheels or wash the vehicle underside.The use of retread tires is notrecommended. Retread tires mayadversely affect the handlingcharacteristics and safety of the vehicle.Dented or bent rims can cause tirepressure loss and damage to the tirebeads. For this reason, check rims fordamage at regular intervals.

103

The rim flanges must be checked forwear before a tire is mounted. Removeburrs, if any.

Warning!

The jack is designed exclusively forjacking up the vehicle at the jacktubes built into either side of thevehicle. Use the jack only to lift thevehicle during a wheel change. Neverget beneath the vehicle while it issupported by the jack. Keep handsand feet away from the area underthe lifted vehicle. Always firmly setparking brake and block wheelsbefore raising vehicle with jack.

Do not disengage parking brake whilethe vehicle is raised. Be certain thatthe jack is always vertical when in use,especially on hills. Always try to usethe jack on level surface. Be sure thatthe jack arm is fully inserted in thejack tube. Lower the vehicle ontosufficient capacity jack stands beforeworking under the vehicle.

Changing Wheels

Move vehicle to a level area which is asafe distance from the roadway.

1. Set parking brake and turn onhazard warning flasher.

2. Move selector lever to position "P"and turn off engine.

3. Prevent vehicle from rolling awayby blocking wheels with - wheelchocks (not supplied with vehicle)or sizable wood block or stone.When changing a wheel on a hill,place chocks on the downhill sideblocking both wheels of the otheraxle. On a level road, place onechock in front of and one behindthe wheel that is diagonallyopposite to the wheel beingchanged.

4 Unfold wrench, loosen but do notyet remove the wheel bolts.

104

5 Remove the protective cover fromthe jack support tube opening byinserting a screwdriver in theopening and prying it out.The tube openings are locateddirectly behind the front wheelhousings and in front of the rearwheel housings.

6. Insert jack arm fully into thetube hole up to the stop. Placejack on firm ground. Positionthe jack so that it is alwaysvertical (plumb-line) as seenfrom the side (see arrow), evenif the vehicle is parked on anincline.

7. Jack up the vehicle until thewheel is clear of the ground.Never start engine while vehicleis raised.

8. Unscrew wheel bolts completely.Keep bolt threads protected fromdirt and sand.

While removing the last bolt, holdwheel against hub to avoid paintdamage on rim,

9 Remove wheel. Grip wheelfrom the sides. Keep handsfrom beneath the wheels.

10 Screw the alignment bolt (1)supplied in the tool kit into theupper-most threaded hole

Warning!

Always replace wheel bolts thatare damaged or rusted.

Never apply oil or grease to wheelbolt threads.

Damaged wheel hub threads shouldbe repaired immediately.

105

11 Clean contact surfaces ofwheel and wheel hub. Installspare wheel on wheel hub.Insert wheel bolts and tightenthem slightly.To avoid paint damage, placewheel flat against hub and hold itthere while installing first wheelbolt.Unscrew the alignment bolt toinstall the last wheel bolt.

12 Lower car. Remove jack andinsert jack tube cover.

13 Unfold wrench and tighten the fivebolts evenly, following thesequence illustrated above, untilall bolts are tight. Observe atightening torque of 110 ft.lb. (150Nm).

14 Correct tire pressure.

Important!

When installing new wheels themounting bolts must be retightenedafter approx. 60 - 300 miles (100 to 500km).

Before storing the jack, the jack armmust be lowered almost to the base ofthe jack.

Warning!

Incorrect mounting bolts orimproperly tightened mounting boltscan cause the wheel to come off. Thiscould cause an accident. Be sure touse the correct mounting bolts.

106

Tire Inflation Pressure

A table (see fuel filler flap) lists the tireinflation pressures specified forsummer and winter tires as well as forthe varying operating conditions.

Important!

Tire pressure changes by approx. 1.5psi (0.1 bar) per 18°F (10°C) of airtemperature change. Keep this in mindwhen checking tire pressure inside agarage - especially in the winter.

Example:

If garage temperature = approx. + 68°F(+ 20°C) and ambient temperature =approx. +32°F (0°C) then the adjustedair pressure = specified air pressure + 3psi (+ 0.2 bar).

Tire pressures listed for light loads areminimum values offering high drivingcomfort.

Increased inflation pressures for heavyloads produce favorable handlingcharacteristics with lighter loads andare perfectly permissible. The ride ofthe vehicle, however, will becomesomewhat harder.

Tire temperature and pressure increasewith the vehicle speed. Tire pressureshould therefore only be corrected oncold tires. Correct tire pressure in warmtires only if pressure has dropped be-low the pressure listed in the table andthe respective operating conditions aretaken into consideration.

An under inflated tire due to a slowleak (e.g. due to a nail in the tire) maycause damage such as tread separation,bulging etc. Regular tire pressurechecks (including the spare tire) atintervals of no more than 14 days aretherefore essential.

If a tire constantly loses air, it shouldbe inspected for damage.

Warning!

Do not over inflate tires. Overinflating tires can result in suddendeflation (blowout) because they aremore likely to become punctured ordamaged by road debris, potholesetc.. Follow recommended inflationpressures.

Do not overload the tires byexceeding the specified vehiclecapacity weight (as indicated by thelabel on the driver's door latch post).Overloading the tires can overheatthem, possibly causing a blowout.

107

Battery

The maintenance-free battery is locatedin the trunk under the right-hand wheelwell cover panel.

The service life of the battery isdependent on its condition of charge.The battery should always be keptsufficiently charged, in order to last anoptimum length of time.

Therefore, we recommend that youhave the battery charge checkedfrequently if you use the vehiclemostly for short distance trips, or ifit is not used for long periods of time.

Only charge a battery with a batterycharger after the battery has beendisconnected from the vehicle electricalcircuit.

When removing and connecting thebattery, always make sure that allelectrical consumers are off and thekey is in steering lock position 0.

While the engine is running the batteryterminal clamps must not be loosened ordetached, otherwise the alternator andother electronic components would bedamaged.

Battery Recycling

Batteries contain materials that canharm the environment with improperdisposal.

Large 12 Volt storage batteries containlead, and smaller watch-type batteries(such as in the Infrared Remote ControlUnit) may contain mercury.

Recycling of batteries is the preferredmethod of disposal.

Many states require sellers of batteriesto accept old batteries for recycling.

Warning!

Never lean over batteries whileconnecting, you might get injured.

Battery fluid contains sulfuric acid.Do not allow this fluid to come incontact with eyes, skin or clothing.In case it does, immediately flushaffected area with water and seekmedical help.

A battery will also produce hydrogengas, which is flammable andexplosive. Keep flames or sparksaway from battery, avoid improperconnection of jumper cables,smoking etc..

If the battery is discharged, the engineshould be started with jumper cablesand the (12 V) battery of anothervehicle.

The battery is located in the trunkbehind the right-hand cover panel.

Warning!

Failure to follow these directionswill cause damage to the electroniccomponents, and can lead to abattery explosion and personalinjury.

Read all instructions beforeproceeding.

Proceed as follows:

1 Position the vehicle with the chargedbattery so that the jumper cables willreach, but never let the vehiclestouch. Make sure the jumper cablesdo not have loose or missinginsulation.

2 On both vehicles:

• Turn off engine and all lightsand accessories, except hazardflashers or work lights.

• Apply parking brake and shiftselector lever to position "P".

Important!

3. Clamp one end of the first jumpercable to the positive (+) terminal ofthe discharged battery and the otherend to the positive (+) terminal ofthe charged battery. Make sure thecable clamps do not touch any othermetal parts.

4. Clamp one end of the second jumpercable to the grounded negative (-)terminal of the charged battery andthe final connection to the negative(-) terminal of the dischargedbattery.

114

Important!

5. Start engine of the vehicle withthe charged battery and run athigh idle. Then start engine ofthe disabled vehicle in theusual manner.

6. After the engine has started,remove jumper cables byexactly reversing the aboveinstallation sequence, startingwith the last connection madefirst. When removing eachclamp, make sure that it doesnot touch any other metal whilethe other end is still attached.

Warning!

Never lean over batteries whileconnecting or jump starting, youmight get injured.

Battery fluid contains sulfuric acid.Do not allow this fluid to come incontact with eyes, skin or clothing.In case it does, immediately flushaffected area with water, and seekmedical help.

A battery will also produce hydrogengas, which is flammable and veryexplosive. Keep flames or sparksaway from battery, avoid improperconnection of jumper cables,smoking etc..

Important!

A discharged battery can freeze atapprox. + 14°F (-10°C). In that case, itmust be thawed out before jumpercables are used.

Jumper cable specifications:

• Minimum cable cross-section of25 mm2 or approx. 2 AWG

• Maximum length of 11.5 ft(3.5 m).

115

Towing the Vehicle

The rear towing eye is located at theright, below the bumper. The fronttowing eye is located on the passengerside behind a flap in the bumper panel.

Flap removal: Insert finger in recess offlap and pull flap out.

Flap installation: Engage flap at bottomand press in top securely

We recommend that the vehicle betransported using flat bed equipment.This method is preferable to other typesof towing.

The vehicle may be towed with allwheels on the ground and the selectorlever in position "N" for distances up to30 miles (50 km) and at a speed not toexceed 30 mph (50 km/h).

To positively avoid a possibility ofdamage to the transmission, however,we recommend to disconnect the driveshaft at the rear axle drive flange onany towing beyond a short tow to anearby garage.

Do not tow with sling-type equipment.Towing with sling-type equipment overbumpy roads will damage radiator andsupports.

Use wheel lift or flat bed equipment.

Warning!

With the engine not running, there isno power assistance for the brakingand steering systems. In this case, itis important to keep in mind that aconsiderably higher degree of effortis necessary to brake and steer thevehicle.

To signal turns while being towed withhazard flasher in use, turn key insteering lock to position 2 and activatecombination switch for left or rightturn signal in usual manner - only theselected turn signal will operate.

Upon canceling the turn signal, thehazard flasher will operate again.

Vehicles with Acceleration SlipControl (ASR)

Caution!

If the vehicle is towed with the frontaxle raised, the key must not be insteering lock position 2. Otherwise, theacceleration slip control willimmediately be engaged and will applythe rear wheel brakes.

116

Cleaning and Care of the Vehicle

Warning!

Many cleaning products can behazardous. Some are poisonous,others are flammable. Always followthe instructions on the particularcontainer. Always open your car'sdoors or windows when cleaning theinside.

Never use fluids or solvents that arenot designed for cleaning your car.

In operation, your vehicle is subjectedto varying external influences which, ifgone unchecked, can attack the paint-work as well as the underbody andcause lasting damage.

Such damage is caused not only byextreme and varying climatic conditions,but also by air pollution, road salt, tar,gravel and stone chipping. Grease andoil, fuel, coolant, brake fluid, birddroppings, tree resins etc. should beremoved immediately to avoid

paint damage. Frequent washing,however, reduces and/or eliminates theaggressiveness and potency of the aboveadverse influences.

More frequent washings are necessaryto deal with unfavorable conditions; forexample, near the ocean, in industrialareas (smoke, exhaust emissions), orduring winter operation.

You should check your vehicle fromtime to time for stone chipping or otherdamage. Any damage should berepaired as soon as possible to preventthe start of corrosion.

In doing so, do not neglect theunderside of the car. A prerequisite for athorough check is a washing of theunderbody followed by a thoroughinspection. Damaged areas need to bereundercoated.

Your vehicle has been treated at thefactory with a wax-base rust proofing inthe body cavities which will last for thelifetime of the vehicle. Post-productiontreatment is neither necessary nor

recommended by Mercedes-Benzbecause of the possibility ofincompatibility between materials usedin the production process and othersapplied later.

We have selected car-care products andcompiled recommendations which arespecially matched to our vehicles andwhich always reflect the latest techno-logy. You can obtain MB car-careproducts at your authorized Mercedes-Benz dealer.

Scratches, corrosive deposits, corrosionor damage due to negligent or incorrectcare cannot always be removed orrepaired with the car-care products re-commended here. In such cases it isbest to seek aid at your authorizedMercedes-Benz dealer.

The following topics deal with thecleaning and care of your vehicle andgive important "how-to" information aswell as references to recommendedMB car-care products.

Additional information can be found inthe booklet titled "Car Care".

117

Engine Cleaning

Corrosion protection, such as MBAnticorrosion Wax should be appliedto the engine compartment after everyengine cleaning. Before applying, allcontrol linkage bushings and jointsshould be lubricated. The poly-V-beltand all pulleys should be protectedfrom any wax.

Car Washing

Before washing your vehicle, removeinsect residues. MB Insect Remover isrecommended. Do not use hot water orwash your car in direct sunlight. Useonly a mild car wash detergent, such asMB Autoshampoo.

Thoroughly spray the car with adiffused jet of water. Direct only a veryweak spray towards the ventilationintake. Use plenty of water and rinsethe sponge and chamois frequently.

Rinse with clear water and thoroughlywipe dry with a chamois. Do not allowcleaning agents to dry on the finish.

Before running the vehicle through anautomatic car wash, fold back theoutside mirrors to prevent them fromgetting damaged.

If the vehicle has been run through anautomatic car wash -in particular one ofthe older installations - rewipe the reces-sed sections in the tail lamps (designedto prevent soiling) if necessary. Nosolvents (fuels, thinners etc.) must beused.

In the winter, thoroughly remove alltraces of road salt as soon as possible.

When washing the underbody, do notforget to clean the inner sides of thewheels.

Tar Stains

Quickly remove tar stains before theydry and become more difficult toremove. MB Tar Remover isrecommended.

Window Cleaning

Use a window cleaning solution onvery dirty or oil-stained windows.

Wiper Blades

Clean the wiper blade rubber with aclean cloth and detergent solution.Replace blades twice a year; oncebefore and once after winter.

138

Engine Oils

Engine oils are specifically tested fortheir suitability in our engines.Therefore, use only engine oilsrecommended by Mercedes-Benz.Information on recommended brands isavailable at your authorized Mercedes-Benz dealer.

Please follow maintenance bookletrecommendations for scheduled oilchanges. Failure to do so could result inengine damage not covered by theMercedes-Benz Limited Warranty.

Engine Oil Additives

Do not blend oil additives with engineoil. They may be harmful to the engineoperation.

Damage or malfunctions resulting fromblending oil additives are not coveredby the Mercedes-Benz LimitedWarranty.

Air Conditioner Refrigerant

Ozone-friendly HFC-134a refrigerantand special lubricating oil is used in theair conditioner system.

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

Brake Fluid

During vehicle operation, the boilingpoint of the brake fluid is continuouslyreduced through the absorption ofmoisture from the atmosphere. Underextremely hard operating conditions,this moisture content can lead to theformation of bubbles in the system thusreducing the system's efficiency.The brake fluid must therefore bereplaced every two years, preferablyin the spring.

It is recommended to use only brakefluid approved by Mercedes-Benz.Your authorized Mercedes-Benz dealerwill provide you with additionalinformation.

Premium Unleaded GasolineCaution!

To maintain the engine's durability andperformance, premium unleadedgasoline must be used. If premiumunleaded is not available and lowoctane fuel is used, follow theseprecautions:

• have the fuel tank filled onlypartially with unleaded regularand fill up with premium unleaded as soon as possible,

• avoid full throttle driving andabrupt acceleration,

• do not exceed an engine speedof 3000 rpm, if the vehicle isloaded with a light load such astwo persons and no luggage,

• do not exceed 2/3of maximumaccelerator pedal position, if thevehicle is fully loaded oroperating in mountainous terrain.

139

Fuel Requirements

Use only Premium unleaded meetingASTM standard D 439:

The octane number (posted at the pump)must be 91 min. It is an average of boththe Research (R) octane number and theMotor (M) octane number: [(R + M)/2].This is also known as ANTI-KNOCKINDEX.

Unleaded gasoline containingoxygenates such as Ethanol, IPA, IBAand TBA can be used provided the ratioof any one of these oxygenates togasoline does not exceed 10%, MTBEnot to exceed 15%.

The ratio of Methanol to gasoline mustnot exceed 3% plus additionalcosolvents.

Using mixtures of Ethanol andMethanol is not allowed,Gasohol, which contains 10% Ethanoland 90% unleaded gasoline, can beused.

These blends must also meet all otherfuel requirements such as resistance tospark knock, boiling range, vaporpressure etc..

Gasoline Additives

A major concern among enginemanufacturers is carbon build up causedby gasoline. Mercedes-Benzrecommends to use only qualitygasoline containing additives thatprevent the build up of carbon deposits.

After an extended period of using fuelswithout such additives, carbon depositscan build up especially on the intakevalves and in the combustion area,leading to engine performance problemssuch as:

• warm-up hesitation,• unstable idle,• knocking/pinging,• misfire,• power loss.

Do not blend other specific fueladditives with fuel. They only result inunnecessary cost, and may be harmfulto the engine operation.

Damage or malfunctions resulting frompoor fuel quality are not covered by theMercedes-Benz Limited Warranty.

140

Coolants

The engine coolant is a mixture of waterand anticorrosion/anti-freeze, whichprovides:

• corrosion protection• freeze protection• boiling protection (by increasing the

boiling point).

The cooling system was filled at thefactory with a coolant providing freezeprotection to approx. -22°F (-30°C) andcorrosion protection.

The coolant solution must be used yearround to provide the necessarycorrosion protection and increase in theboil-over protection. You should have itreplaced every 3 years.

To provide the important corrosionprotection, the solution must be at least45% anticorrosion/antifreeze (equals afreeze protection to approx. -22°F[-30°C]). If you use a solution that ismore than 55% anticorrosion/antifreeze(freeze protection to approx. -49 °F[-45°C]), the engine temperature willincrease due to the lower

heat transfer capability of the solution.Therefore, do not use more than thisamount of anti-corrosion/antifreeze.If the coolant level is low, water andMB anticorrosion/antifreeze should beused to bring it up to the proper level(have cooling system checked for signsof leakage).

The water in the cooling system mustmeet minimum requirements, which areusually satisfied by normal drinkingwater. If you are not sure about thewater quality, consult your authorizedMercedes-Benz dealer.

Anticorrosion/antifreeze

Your vehicle contains a number ofaluminum parts. The use of aluminumcomponents in motor vehicle enginesnecessitates that anticorrosion/antifreeze coolant used in such enginesbe specifically formulated to protect thealuminum parts. (Failure to use suchanticorrosion/antifreeze coolant willresult in a significantly shortenedservice life.)

Therefore the following product isstrongly recommended for use in yourcar: Mercedes-BenzAnticorrosion/Antifreeze Agent.Before the start of the winter season (oronce a year in the hot southern regions),you should have the anticorrosion/antifreeze concentration checked.

Consumer Information

This has been prepared as required of allmanufacturers of passenger cars underTitle 49, Code of U.S. FederalRegulations, Part 575 pursuant to the"National Traffic and Motor VehicleSafety Act of 1966".

Uniform Tire Quality Grading

Refer to the tire sidewall for the specifictire grades for the tires with which thisvehicle is equipped.

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

Treadwear

The treadwear grade is a comparativerating based on the wear rate of the tirewhen tested under controlled conditionson a specified government test course.For example, a tire graded 150 wouldwear one and one-half (11/2) times aswell on the government course as a tiregraded 100. The relative performance oftires depends upon the actual conditionsof their use, however, and may

depart significantly from the norm due tovariations in driving habits, servicepractices and differences in roadcharacteristics and climate.

Traction "A", "B", "C"

The traction grades, from highest tolowest, are "A", "B", and "C", andthey represent the tire's ability to stopon wet pavement as measured undercontrolled conditions on specifiedgovernment test surfaces of asphalt andconcrete. A tire marked "C" may havepoor traction performance.

Warning!

The traction grade assigned to this tireis based on braking (straight ahead)traction tests and does not includecornering (turning) traction.

Temperature "A", "B", "C"

The temperature grades are "A" (thehighest), "B", and "C", representing thetire's resistance to the generation of heatand its ability to dissipate heat when

tested under controlled conditions on aspecified indoor laboratory test wheel.Sustained high temperature can causethe material of the tire to degenerate andreduce tire life, and excessive tempera-ture can lead to sudden tire failure. Thegrade "C" corresponds to a level ofperformance which all passenger cartires must meet under the Federal MotorVehicle Safety Standard No. 109. Grades"B" and "A" represent higher levels ofperformance on the laboratory testwheel than the minimum required bylaw.

Warning!

The temperature grade for this tire isestablished for a tire that is properlyinflated and not overloaded. Excessivespeed, underinflation, or excessiveloading, either separately or incombination, can cause excessive heatbuild up and possible tire failure.
