For your safety, we strongly recommend that you vst an authorzed Mercedes-Benz Center mmedately to have the system checked; otherwse the SRS may not be actvated when needed n an accdent, whch could result n serous or fatal njury, or t mght deploy unexpectedly and unnecessarly whch could also result n njury. In addton, mproper work on the SRS creates a rsk of renderng the SRS noperatve or causng unntended ar bag deployment. Work on the SRS must therefore only be performed by qualfed techncans. Contact an authorzed Mercedes-Benz Center. Ar bags Warnng! Ar bags are desgned to reduce the potental of njury and fatalty n certan frontal mpacts (front ar bags), or sde mpacts (sde mpact ar bags and head protecton wndow curtan ar bags). However, no system avalable today can totally elmnate njures and fataltes. The actvaton of the ar bags temporarly releases a small amount of dust from the ar bags. Ths dust, however, s nether njurous to your health, nor does t ndcate a fre n the vehcle. The dust mght cause some temporary breathng dffculty for people wth asthma or other breathng trouble. To avod ths, you may wsh to get out of the vehcle as soon as t s safe to do so. If you have any breathng dffculty but cannot get out of the vehcle after the ar bag nflates, then get fresh ar by openng a wndow or door. Warnng! To reduce the rsk of njury when the front ar bags nflate, t s very mportant for the drver and front passenger to always be n a properly seated poston and to wear your seat belts. For maxmum protecton n the event of a collson always be n normal seated poston wth your back aganst the backrest. Fasten your seat belt and make sure that t s properly postoned on your body. Snce the ar bag nflates wth consderable speed and force, a proper seatng and hands on steerng wheel poston wll help to keep you at a safe dstance from the ar bag. Occupants who are unbelted, out of poston or too close to the ar bag can be serously njured by an ar bag as t nflates wth great force n the blnk of an eye: St properly belted n a nearly uprght poston wth your back aganst the seat backrest. 59

The dstance from the center of the drver s breastbone to the center of the ar bag cover on the steerng wheel must be at least ten nches (25 cm) or more. You should be able to accomplsh ths by a combnaton of adjustments to the seat and steerng wheel. If you have any problems, please see an authorzed Mercedes-Benz Center. Do not lean wth your head or chest close to the steerng wheel or dashboard. Keep hands on the outsde of steerng wheel rm. Placng hands and arms nsde the rm can ncrease the rsk and potental severty of hand/arm njury when drver front ar bag nflates. Adjust the front passenger seat as far as possble rearward from the dashboard when the seat s occuped. Occupants, especally chldren, should never lean ther heads n the area of the door where the sde ar bag nflates. Ths could result n serous njures or death should the ar bag be trggered. Always st nearly uprght, properly use the seat belts and approprate sze nfant or chld restrant system. Chldren 12 years old and under must never rde n the front seat, except n a Mercedes-Benz authorzed BabySmart TM1 compatble chld seat, whch operates wth the BabySmart TM system nstalled n the vehcle to deactvate the passenger front ar bag when t s properly nstalled. Otherwse they wll be struck by the ar bag when t nflates n a crash. If ths happens, serous or fatal njury wll result. Falure to follow these nstructons can result n severe njures to you or other occupants. If you sell your vehcle, t s mportant that you make the buyer aware of ths safety nformaton.

62 Safety and Securty Occupant safety Warnng! Accdent research shows that the safest place for chldren n an automoble s n the rear seat. Should you choose to place a chld 12 years old or under n the front passenger seat of your vehcle, you must properly use a BabySmart TM1 chld restrant whch wll turn off the passenger front ar bag. BabySmart TM wll not, however, turn off any sde mpact ar bag. It should be noted that wth respect to both front and rear sde mpact ar bags there s a possblty for a sde ar bag related njury f occupants, especally chldren, are not properly seated or restraned when next to a sde ar bag whch needs to deploy rapdly n a sde mpact n order to do ts job. 1 BabySmart TM s a trademark of Semens Automotve Corp. To help avod the possblty of njury, please follow these gudelnes: (1) Occupants, especally chldren, should never place ther bodes or lean ther heads n the area of the door where the sde ar bag nflates. Ths could result n serous njures or death should the sde ar bag be actvated. (2) Always st nearly uprght, properly use the seat belts and use an approprately szed nfant or chld restrant system for all chldren 12 years old or under. (3) Always wear seat belts properly. If you beleve that, even wth the use of these gudelnes, t would be safer for your rear seat occupants to have both rear door mounted sde ar bags deactvated, then deactvaton can be accomplshed upon your wrtten request to do so at an authorzed Mercedes-Benz Center at an addtonal cost. Please contact your local authorzed Mercedes-Benz Center or call our Customer Assstance Center at FOR-MERCedes ( ) for detals. Ar bags are desgned to actvate only n certan frontal mpacts (front ar bags) and n sde mpacts (sde mpact and head protecton wndow curtan ar bags) whch exceed preset thresholds. Only durng these types of mpacts, f of suffcent severty to meet the deployment tresholds, wll they provde ther supplemental protecton. The drver and passengers should always wear ther seat belts.

66 Safety and Securty Occupant safety Warnng! Warnng! Warnng! Always fasten your seat belt before drvng off. Always make sure your passengers are properly restraned, even those sttng n the rear and pregnant women. Falure to wear and properly fasten and poston your seat belt greatly ncreases your rsk of njures and ther lkely severty n an accdent. You and your passengers should always wear seat belts. If you are ever n an accdent, your njures can be consderably more severe wthout your seat belt properly buckled. Wthout your seat belt buckled, you are much more lkely to ht the nteror of the vehcle or be ejected from t. You can be serously njured or klled. In the same crash, the possblty of njury or death s lessened f you are properly wearng your seat belt. Ar bags can only protect as they are desgned f the occupants are properly wearng ther seat belts. Never rde n a movng vehcle wth the seat backrest n an excessvely reclned poston as ths can be dangerous. You could slde under the seat belt n a collson. If you slde under t, the belt would apply force at the abdomen or neck. That could cause serous or even fatal njures. The seat backrest and seat belt provde the best restrant when the wearer s n a nearly uprght poston and the belt s properly postoned on the body. Warnng! Never let more people rde n the vehcle than there are seat belts avalable. Be sure everyone rdng n the vehcle s correctly restraned wth a separate seat belt. Never use a seat belt for more than one person at a tme. Damaged seat belts or belts that were hghly stressed n an accdent must be replaced and ther anchorng ponts must also be checked. Only use seat belts whch have been approved by Mercedes-Benz. Do not make any modfcatons to the seat belts. Ths can lead to unntended actvaton of the ETDs or to falure. Do not bleach or dye seat belts as ths may severely weaken them. In a crash, they may not be able to provde adequate protecton. Have all work carred out only by qualfed techncans.

67 Safety and Securty Occupant safety Warnng! USE SEAT BELTS PROPERLY Seat belts can only work when used properly. Never wear seat belts n any other way than as descrbed n ths secton, as that could result n serous njures n case of an accdent. Each occupant should wear ther seat belt at all tmes, because seat belts help reduce the lkelhood of and potental severty of njures n accdents, ncludng rollovers. The ntegrated restrant system ncludes SRS (drver ar bag, passenger front ar bag, sde mpact ar bags, head protecton wndow curtan ar bags for sde wndows), ETD (seat belt emergency tensonng devce), and front seat knee bolsters. The system s desgned to enhance the protecton offered to properly belted occupants n certan frontal (front ar bags and ETD) and sde (sde mpact, wndow curtan ar bags and ETD) mpacts whch exceed preset deployment thresholds. Never wear the shoulder belt under your arm, aganst your neck or off your shoulder. In a crash, your body would move too far forward. That would ncrease the chance of head and neck njures. The belt would also apply too much force to the rbs or abdomen, whch could severely njure nternal organs such as your lver or spleen. Never wear belts over rgd or breakable objects n or on your clothng, such as eyeglasses, pens, keys, etc., as these mght cause njures. Poston the lap belt as low as possble on your hps and not across the abdomen. If the belt s postoned across your abdomen, t could cause serous njures n a crash. Never use a seat belt for more than one person at a tme. Do not fasten a seat belt around a person and another person or other objects. Belts should not be worn twsted. In a crash, you wouldn t have the full wdth of the belt to manage mpact forces. The twsted belt aganst your body could cause njures. Pregnant women should also use a lap-shoulder belt. The lap belt porton should be postoned as low as possble on the hps to avod any possble pressure on the abdomen. Never place your feet on the nstrument panel, dashboard or on the seat. Always keep both feet on the floor n front of the seat. 66

68 Safety and Securty Occupant safety Emergency tensonng devce (ETD), seat belt force lmter The seat belts for the front and rear outer seats are equpped wth emergency tensonng devces and belt force lmters. The ETD s desgned to actvate n the followng cases: n frontal or rear-end mpacts exceedng a preset severty level. f the restrant systems are operatonal and functonng correctly. See 1 ndcator lamp ( page 58). The ETDs for the front seats wll only actvate f the respectve front seat belt s fastened (latch plate properly nserted nto buckle). The ETDs for the rear outer seats wll actvate wth or wthout the respectve seat belt fastened. In an mpact, emergency tensonng devces remove slack from the belts n such a way that the seat belts ft more snugly aganst the body. Belt force lmters reduce the force exerted by the seat belts on occupants durng a crash. Warnng! An emergency tensonng devce (ETD) that was actvated must be replaced. When scrappng the emergency tensonng devce, our safety nstructons must be followed. These are avalable at your authorzed Mercedes-Benz Center.!

78 Drvng safety systems In ths secton you wll fnd nformaton on the followng drvng safety systems: ABS (Antlock Brake System) BAS (Brake Assst System) ESP (Electronc Stablty Program) 4MATIC (Four Wheel Electronc Tracton System) In wnter operaton, the maxmum effectveness of the ABS, ESP, and 4MATIC (f so equpped) s only acheved wth wnter tres (M+S tres), or snow chans as requred. Warnng! The followng factors ncrease the rsk of accdents: Excessve speed, especally n turns Wet and slppery road surfaces Followng another vehcle too closely The ABS, BAS, ESP, and 4MATIC (f so equpped) cannot reduce ths rsk. Always adjust your drvng style to the prevalng road and weather condtons. ABS Warnng! Safety and Securty Drvng safety systems Do not pump the brake pedal. Use frm, steady brake pedal pressure nstead. Pumpng the brake pedal defeats the purpose of the ABS and sgnfcantly reduces brakng effectveness. The Antlock Brake System (ABS) regulates the brake pressure so that the wheels do not lock durng brakng. Ths allows you to mantan the ablty to steer your vehcle. The ABS s functonal above a speed of approxmately 5 mph (8 km/h) ndependent of road surface condtons. On slppery road surfaces, the ABS wll respond even to lght brake pressure. The - ndcator lamp n the nstrument cluster ( page 24) comes on when you swtch on the gnton. It goes out when the engne s runnng. 77

79 Safety and Securty Drvng safety systems Brakng At the nstant one of the wheels s about to lock up, a slght pulsaton can be felt n the brake pedal, ndcatng that the ABS s n the regulatng mode. Keep frm and steady pressure on the brake pedal whle experencng the pulsaton. Contnuous steady brake pedal pressure yelds the advantages provded by the ABS, namely brakng power and ablty to steer the vehcle. The pulsatng brake pedal can be an ndcaton of hazardous road condtons and functons as a remnder to take extra care whle drvng. Emergency brake maneuver Keep contnuous full pressure on the brake pedal. Warnng! The ABS cannot prevent the natural laws of physcs from actng on the vehcle, nor can t ncrease brakng or steerng effcency beyond that afforded by the condton of the vehcle brakes and tres or the tracton afforded. The ABS cannot prevent accdents, ncludng those resultng from excessve speed n turns, followng another vehcle too closely, or hydroplanng. Only a safe, attentve, and skllful drver can prevent accdents. The capabltes of an ABS equpped vehcle must never be exploted n a reckless or dangerous manner whch could jeopardze the user s safety or the safety of others. For more nformaton, see Practcal hnts ( page 342) and ( page 351). BAS The Brake Assst System (BAS) operates n emergency stuatons. If you apply the brakes very quckly, the BAS automatcally provdes full brake boost, thereby potentally reducng the brakng dstance. Apply contnuous full brakng pressure untl the emergency brakng stuaton s over. The ABS wll prevent the wheels from lockng. When you release the brake pedal, the brakes functon agan as normal. The BAS s then deactvated. Warnng! If the BAS s malfunctonng, the brake system s stll functonng normally, but wthout the addtonal brake boost avalable that BAS would normally provde n an emergency brakng maneuver. Therefore, the brakng dstance may ncrease. 78

For more nformaton, see Practcal hnts ( page 352). ESP The Electronc Stablty Program (ESP) s operatonal as soon as the engne s runnng and montors the vehcle's tracton (force of adhesve frcton between the tres and the road surface) and handlng. The ESP recognzes when a wheel s spnnng or f the vehcle starts to skd. By applyng brakes to the approprate wheel and by lmtng the engne output, the ESP works to stablze the vehcle. The ESP s especally useful whle drvng off and on wet or slppery road surfaces. The ESP also stablzes the vehcle durng brakng maneuvers. The ESP warnng lamp v n the speedometer flashes when the ESP s engaged. The ESP warnng lamp v n the speedometer comes on when you swtch on the gnton. It goes out when the engne s runnng. Warnng! Never swtch off the ESP when you see the ESP warnng lamp v flashng n the speedometer. In ths case, proceed as follows: Whle drvng off, apply as lttle throttle as possble. Whle drvng, ease up on the accelerator. Adapt your speed and drvng style to the prevalng road condtons. Falure to observe these gudelnes could cause the vehcle to skd. The ESP cannot prevent accdents resultng from excessve speed. 79

The possblty of a serous or even fatal accdent are greatly ncreased when you drnk or take drugs and drve. Do not drnk or take drugs and drve or allow anyone to drve who has been drnkng or takng drugs. Warnng! Power assstance Keep drver s foot area clear at all tmes. Objects stored n ths area may mpar pedal movement. Warnng! Wth the engne not runnng, there s no power assstance for the brake and steerng systems. In ths case, t s mportant to keep n mnd that a consderably hgher degree of effort s necessary to brake and steer the vehcle. 281

283 Operaton Drvng nstructons Brakes Warnng! After drvng n heavy ran for some tme wthout applyng the brakes or through water deep enough to wet brake components, the frst brakng acton may be somewhat reduced and ncreased pedal pressure may be necessary to obtan expected brakng effect. Mantan a safe dstance from vehcles n front. Restng your foot on the brake pedal wll cause excessve and premature wear of the brake pads. It can also result n the brakes overheatng, thereby sgnfcantly reducng ther effectveness. It may not be possble to stop the vehcle n suffcent tme to avod an accdent. To help prevent brake dsk corroson after drvng on wet road surfaces (partcularly salted roads), t s advsable to brake the vehcle wth consderable force pror to parkng. The heat generated serves to dry the brakes. If your brake system s normally only subject to moderate loads, you should occasonally test the effectveness of the brakes by applyng above-normal brakng pressure at hgher speeds. Ths wll also enhance the grp of the brake pads.! Be very careful not to endanger other road users when you apply the brakes. Refer to the descrpton of the Brake Assst System (BAS) ( page 78). If the parkng brake s released and the brake warnng lamp n the nstrument cluster stays on, the brake flud level n the reservor s too low. Brake pad wear or a leak n the system may be the reason for low brake flud n the reservor. Have the brake system nspected mmedately. Contact an authorzed Mercedes-Benz Center. All checks and servce work on the brake system should be carred out by qualfed techncans only. Contact an authorzed Mercedes-Benz Center. Only nstall brake pads and brake flud recommended by Mercedes-Benz. Warnng! If other than recommended brake pads are nstalled, or other than recommended brake flud s used, the brakng propertes of the vehcle can be degraded to an extent that safe brakng s substantally mpared. Ths could result n an accdent. 282

284 Operaton Drvng nstructons! When drvng down long and steep grades, releve the load on the brakes by shftng nto a lower gear to use the engne s brakng power. Ths helps prevent overheatng of the brakes and reduces brake pad wear. After hard brakng, t s advsable to drve on for some tme, rather than mmedately parkng, so that the ar stream wll cool down the brakes faster. Drvng off Apply the brakes to test them brefly after drvng off. Perform ths procedure only when the road s clear of other traffc. Warm up the engne smoothly. Do not place full load on the engne untl the operatng temperature has been reached. When startng off on a slppery surface, do not allow a drve wheel to spn for an extended perod wth the ESP swtched off. Dong so may cause serous damage to the drvetran whch s not covered by the Mercedes-Benz Lmted Warranty.! Smultaneously depressng the accelerator pedal and applyng the brake reduces engne performance and causes premature brake and drvetran wear. Parkng! Set the parkng brake whenever parkng or leavng the vehcle. In addton, move gear selector lever to poston P (manual transmsson: frst or reverse gear). When parkng on hlls, always turn front wheels towards the road curb. Warnng! Do not park ths vehcle n areas where combustble materals such as grass, hay or leaves can come nto contact wth the hot exhaust system, as these materals could be gnted and cause a vehcle fre. To reduce the rsk of personal njury as a result of vehcle movement, before turnng off the engne and leavng the vehcle always: Keep rght foot on brake pedal. Frmly depress parkng brake pedal. Move the gear selector lever to poston P (manual transmsson: frst or reverse gear). Slowly release brake pedal. When parked on an nclne, turn front wheels towards the road curb. Turn the SmartKey n the starter swtch to poston 0 and remove the SmartKey from the starter swtch. Take the SmartKey wth you and lock the vehcle when leavng. 283

285 Operaton Drvng nstructons Tres Warnng! If you feel a sudden sgnfcant vbraton or rde dsturbance, or you suspect that possble damage to your vehcle has occurred, you should turn on the hazard warnng flashers, carefully slow down, and drve wth cauton to an area whch s a safe dstance from the road. Inspect the tres and the vehcle underbody for possble damage. If the vehcle or tres appear unsafe, have t towed to the nearest Mercedes-Benz Center or tre dealer for repars. Treadwear ndcators (TWI) are requred by law. These ndcators are located n sx places on the tread crcumference and become vsble at a tread depth of approxmately 1 / 16 n (1.6 mm), at whch pont the tre s consdered worn and should be replaced. The treadwear ndcator appears as a sold band across the tread. Warnng! Although the applcable federal motor vehcle safety laws consder a tre to be worn when the treadwear ndcators (TWI) become vsble at approxmately 1 / 16 n (1.6 mm), we recommend that you do not allow your tres to wear down to that level. As tread depth approaches 1 / 8 n (3 mm), the adheson propertes on a wet road are sharply reduced. Dependng upon the weather and/or road surface (condtons), the tre tracton vares wdely. Specfed tre nflaton pressures must be mantaned. Ths apples partcularly f the tres are subjected to hgh loads (e.g. hgh speeds, heavy loads, hgh ambent temperatures). Warnng! Hydroplanng Do not drve wth a flat tre. A flat tre affects the ablty to steer or brake the vehcle. You may lose control of the vehcle. Contnued drvng wth a flat tre or drvng at hgh speed wth a flat tre wll cause excessve heat buld-up and possbly a fre. Dependng on the depth of the water layer on the road, hydroplanng may occur, even at low speeds and wth new tres. Reduce vehcle speed, avod track grooves n the road and apply brakes cautously n the ran. 284

286 Operaton Drvng nstructons Tre tracton The safe speed on a wet, snow covered or cy road s always lower than on a dry road. You should pay partcular attenton to the condton of the road whenever the outsde temperatures are close to the freezng pont. Warnng! If ce has formed on the road, tre tracton wll be substantally reduced. Under such weather condtons, drve, steer and brake wth extreme cauton. Mercedes-Benz recommends M+S rated radal-ply tres wth a mnmum tread depth of approxmately 1 / 6 n (4 mm) on all four wheels for the wnter season to ensure normal balanced handlng characterstcs. On packed snow, they can reduce your stoppng dstance compared to summer tres. Stoppng dstance, however, s stll consderably greater than when the road s not covered wth snow or ce. Exercse approprate cauton.! Avod spnnng of a drve wheel. Ths may cause serous damage to the drvetran whch s not covered by the Mercedes-Benz Lmted Warranty. Tre speed ratng Regardless of the tre speed ratng, local speed lmts should be obeyed. Use prudent drvng speeds approprate to prevalng condtons. Warnng! Even when permtted by law, never operate a vehcle at speeds greater than the maxmum speed ratng of the tres. Exceedng the maxmum speed for whch tres are rated can lead to sudden tre falure, causng loss of vehcle control and possbly resultng n an accdent and/or personal njury and possble death, for you and for others. 285

287 Operaton Drvng nstructons C 230 Kompressor (Canada only), C240, C2404MATIC, C320(USAonly), C3204MATIC Your vehcle s factory equpped wth H -rated tres, whch have a speed ratng of 130 mph (210 km/h).

An electronc speed lmter prevents your vehcle from exceedng a speed of 155 mph (250 km/h). For nformaton on tre speed ratng for wnter tres, see Wnter tres ( page 330). For addtonal general nformaton on tre speed markngs on tre sdewall, ( page 318). Wnter drvng nstructons The most mportant rule for slppery or cy roads s to drve sensbly and to avod abrupt acceleraton, brakng and steerng maneuvers. Do not use the cruse control system under such condtons. When the vehcle s n danger of skddng, move gear selector lever to poston N or n case of manual transmsson declutch. Try to keep the vehcle under control by correctve steerng acton. For nformaton on drvng wth snow chans, see Snow chans ( page 331). Warnng! On slppery road surfaces, never downshft n order to obtan brakng acton. Ths could result n drve wheel slp and reduced vehcle control. Your vehcle s ABS wll not prevent ths type of control loss.

288 Operaton Drvng nstructons Road salts and chemcals can adversely affect brakng effcency. Increased pedal force may become necessary to produce the normal brakng effect. Depressng the brake pedal perodcally when travelng at length on salt-strewn roads can brng road-salt-mpared brakng effcency back to normal. If the vehcle s parked after beng drven on salt-treated roads, the brakng effcency should be tested as soon as possble after drvng s resumed. Warnng! Make sure not to endanger any other road users when carryng out these brakng maneuvers. Warnng! If the vehcle becomes stuck n snow, make sure snow s kept clear of the exhaust ppe and from around the vehcle wth the engne runnng. Otherwse, deadly carbon monoxde (CO) gases may enter vehcle nteror resultng n unconscousness and death. To assure suffcent fresh ar ventlaton, open a wndow slghtly on the sde of the vehcle not facng the wnd Warnng! The outsde temperature ndcator s not desgned to serve as an ce-warnng devce and s therefore unsutable for that purpose. Indcated temperatures just above the freezng pont do not guarantee that the road surface s free of ce. For more nformaton, see Wnter drvng ( page 330). Standng water! Do not drve through flooded areas or water of unknown depth. Before drvng through water, determne ts depth. Never accelerate before drvng nto water. The bow wave could force water nto the engne and auxlary equpment, thus damagng them. If you must drve through standng water, drve slowly to prevent water from enterng the passenger compartment or the engne compartment. Water n these areas could cause damage to electrcal components or wrng of the engne or transmsson, or could result n water beng ngested by the engne through the ar ntake causng severe nternal engne damage. Any such damage s not covered by the Mercedes-Benz Lmted Warranty. 287

289 Operaton Drvng nstructons Passenger compartment Warnng! Drvng abroad Always fasten tems beng carred as securely as possble. In an accdent, durng hard brakng or sudden maneuvers, loose tems wll be thrown around nsde the vehcle, and cause njury to vehcle occupants unless the tems are securely fastened n the vehcle. The trunk s the preferred place to carry objects. Abroad, there s an extensve Mercedes-Benz servce network at your dsposal. If you plan to drve nto areas whch are not lsted n the ndex of your Mercedes-Benz Center drectory, you should request pertnent nformaton from an authorzed Mercedes-Benz Center. Control and operaton of rado transmtters COMAND*, rado and telephone* Warnng! Please do not forget that your prmary responsblty s to drve the vehcle safely. Only operate the COMAND (Cockpt Management and Data System), rado or telephone 1 f road, weather and traffc condtons permt. Bear n mnd that at a speed of just 30 mph (approxmately 50 km/h), your vehcle s coverng a dstance of 44 feet (approxmately 14 m) every second. 1 Observe all legal requrements Telephones* and two-way rados Warnng! Never operate rado transmtters equpped wth a bult-n or attached antenna (.e. wthout beng connected to an external antenna) from nsde the vehcle whle the engne s runnng. Dong so could lead to a malfuncton of the vehcle s electronc system, possbly resultng n an accdent and personal njury. Rado transmtters, such as a portable telephone or a ctzens band unt should only be used nsde the vehcle f they are connected to an antenna that s nstalled on the outsde of the vehcle. Refer to the rado transmtter operaton nstructons regardng use of an external antenna. 288

290 Operaton Drvng nstructons Catalytc converter Your Mercedes-Benz s equpped wth monolthc-type catalytc converters, an mportant element n conjuncton wth the oxygen sensors to acheve substantal control of the pollutants n the exhaust emssons. Keep your vehcle n proper operatng condton by followng our recommended mantenance nstructons as outlned n your Mantenance Booklet.! To prevent damage to the catalytc converters, only use premum unleaded gasolne n ths vehcle. Any notceable rregulartes n engne operaton should be repared promptly. Otherwse, excessve unburned fuel may reach the catalytc converter, causng t to overheat and potentally start a fre. Warnng! As wth any vehcle, do not dle, park or operate ths vehcle n areas where combustble materals such as grass, hay or leaves can come nto contact wth the hot exhaust system, as these materals could be gnted and cause a vehcle fre. Emsson control Certan systems of the engne serve to keep the toxc components of the exhaust gases wthn permssble lmts requred by law. These systems, of course, wll functon properly only when mantaned strctly accordng to factory specfcatons. Any adjustments on the engne should, therefore, be carred out only by qualfed Mercedes-Benz Center authorzed techncans. Engne adjustments should not be altered n any way. Moreover, the specfed servce jobs must be carred out regularly accordng to Mercedes-Benz servcng requrements. For detals refer to the Mantenance Booklet. 289

291 Operaton Drvng nstructons Warnng! Inhalaton of exhaust gas s hazardous to your health. All exhaust gas contans carbon monoxde, and nhalng t can cause unconscousness and lead to death. Do not run the engne n confned areas (such as a garage) whch are not properly ventlated. If you thnk that exhaust gas fumes are enterng the vehcle whle drvng, have the cause determned and corrected mmedately. If you must drve under these condtons, drve only wth at least one wndow fully open at all tmes. Coolant temperature Durng severe operatng condtons and stop-and-go cty traffc, the coolant temperature may rse close to approxmately 248 F (120 C). The engne should not be operated wth the coolant temperature over 248 F (120 C). Dong so may cause serous engne damage whch s not covered by the Mercedes-Benz Lmted Warranty. Warnng! Drvng when your engne s badly overheated can cause some fluds, whch may have leaked nto the engne compartment, to catch fre. You could be serously burned. Steam from an overheated engne can cause serous burns and can occur just by openng the hood. Stay away from the engne f you see or hear steam comng from t. Turn off the engne, get out of the vehcle and do not stand near the vehcle untl the engne has cooled down. 290

303 Operaton Tres and wheels See an authorzed Mercedes-Benz Center for nformaton on tested and recommended rms and tres for summer and wnter operaton. They can also offer advce concernng tre servce and purchase. Warnng! 302 Replace rms or tres wth the same desgnaton, manufacturer and type as shown on the orgnal part. See an authorzed Mercedes-Benz Center for further nformaton. If ncorrectly szed rms and tres are mounted: The wheel brakes or suspenson components can be damaged. The operatng clearance of the wheels and the tres may no longer be correct. Warnng! Worn, old tres can cause accdents. If the tre tread s badly worn, or f the tres have sustaned damage, replace them. When replacng rms, only use genune Mercedes-Benz wheel bolts specfed for the partcular rm type. Falure to do so can result n the bolts loosenng and possbly an accdent. Retreaded tres are not tested or recommended by Mercedes-Benz, snce prevous damage cannot always be recognzed on retreads. The operatng safety of the vehcle cannot be assured when such tres are used. Important gudelnes Only use sets of tres and rms of the same type and make. Tres must be of the correct sze for the rm. Break n new tres for approxmately 60 mles (100 km) at moderate speeds. Regularly check the tres and rms for damage. Dented or bent rms can cause tre nflaton pressure loss and damage to the tre beads. If vehcle s heavly loaded, check tre nflaton pressure and correct as requred. Do not allow your tres to wear down too far. Adheson propertes on wet roads are sharply reduced at tread depths under 1 / 8 n (3 mm). When replacng ndvdual tres, you should mount new tres on the front wheels frst (on vehcles wth same-szed wheels all around).

304 Operaton Tres and wheels Tre care and mantenance Warnng! Regularly check the tres for damage. Damaged tres can cause tre nflaton pressure loss. As a result, you could lose control of your vehcle. Worn, old tres can cause accdents. If the tre tread s badly worn, or f the tres have sustaned damage, replace them. Regularly check your tre nflaton pressure at least once a month. For more nformaton on checkng tre nflaton pressure see Recommended tre nflaton pressure ( page 311). Tre nspecton Every tme you check your tre nflaton pressure, you should also nspect your tres for the followng: excessve treadwear ( page 304) cord or fabrc showng through the tre s rubber bumps, bulges, cuts, cracks or splts n the tread or sde of the tre Replace the tre f you fnd any of the above condtons. Make sure you also nspect the spare tre perodcally for condton and nflaton. Spare tres wll age and become worn over tme even f never used, and thus should be nspected and replaced when necessary. Lfe of tre The servce lfe of a tre s dependent upon varyng factors ncludng but not lmted to: Drvng style Tre nflaton pressure Dstance drven Warnng! Tres and spare tre should be replaced after sx years, regardless of the remanng tread. 303

305 Operaton Tres and wheels Tread depth Do not allow your tres to wear down too far. Adheson propertes on wet roads are sharply reduced at tread depths under 1 / 8 n (3 mm). Treadwear ndcators (TWI) are requred by law. These ndcators are located n sx places on the tread crcumference and become vsble at a tread depth of approxmately 1 / 16 n (1.6 mm), at whch pont the tre s consdered worn and should be replaced. Recommended mnmum tre tread depth: Summer tres 1 / 8 n (3 mm) Wnter tres 1 / 6 n (4 mm) Warnng! Although the applcable federal motor safety laws consder a tre to be worn when the treadwear ndcators (TWI) become vsble at approxmately 1 / 16 n (1.6 mm), we recommend that you do not allow your tres to wear down to that level. As tread depth approaches 1 / 8 n (3 mm), the adheson propertes on a wet road are sharply reduced. Dependng upon the weather and/or road surface (condtons), the tre tracton vares wdely. 1 TWI (TreadWear Indcator) The treadwear ndcator appears as a sold band across the tread. Storng tres! Keep unmounted tres n a cool, dry place wth as lttle exposure to lght as possble. Protect tres from contact wth ol, grease and gasolne. Cleanng tres! Never use a round nozzle to power wash tres. The ntense jet of water can result n damage to the tre. Always replace a damaged tre. 304

306 Operaton Tres and wheels Drecton of rotaton Undrectonal tres offer added advantages, such as better hydroplanng performance. To beneft, however, you must make sure the tres rotate n the drecton specfed. An arrow on the sdewall ndcates the ntended drecton of rotaton (spnnng) of the tre. Spare wheels may be mounted aganst the drecton of rotaton (spnnng) even wth a undrectonal tre for temporary use only untl the regular drve wheel has been repared or replaced. Always observe and follow applcable temporary use restrctons and speed lmtatons ndcated on the spare wheel. Loadng the vehcle Two labels on your vehcle show how much weght t may properly carry. The Tre and Loadng Informaton placard (Example A) or the Vehcle Tre Informaton placard (Example B) can be found on the drver s door B-pllar. Ths placard tells you mportant nformaton about the number of people that can be n the vehcle and the total weght that can be carred n the vehcle. It also contans nformaton on the proper sze and recommended tre nflaton pressures for the orgnal equpment tres on your vehcle. The Certfcaton label, also found on the drver s door B-pllar tells you about the gross weght capacty of your vehcle, called the ross Vehcle Weght Ratng (VWR). The VWR ncludes the weght of the vehcle, all occupants, fuel and cargo. The Certfcaton label also tells you about the front and rear axle weght capacty, called the ross Axle Weght Ratng (AWR).

Step 1 (Vehcles equpped wth placard Example B) Locate the headng Vehcle Capacty Weght on your vehcle s placard. Step 2 Determne the combned weght of the drver and passengers that wll be rdng n your vehcle. Step 3 Subtract the combned weght of the drver and passengers from XXX klograms or XXX lbs. Step 4 The resultng fgure equals the avalable amount of cargo and luggage load capacty. For example, f the XXX amount equals 1400 lbs. and there wll be fve 150 lbs. passengers n your vehcle, the amount of avalable cargo and luggage load capacty s 650 lbs. ( (5 x150) = 650 lbs.) Step 5 Determne the combned weght of luggage and cargo beng loaded on the vehcle. That weght may not safely exceed the avalable cargo and luggage load capacty calculated n step 4. Step 6 (f applcable) If your vehcle wll be towng a traler, load from your traler wll be transferred to your vehcle. Consult ths manual to determne how ths reduces the avalable cargo and luggage load capacty of your vehcle ( page 310). The followng table shows examples on how to calculate total and cargo load capactes wth varyng seatng confguratons and number and sze of occupants. The followng examples use a load lmt of 1500 lbs.

You can obtan the VWR and AWR from the Certfcaton label. The Certfcaton Label can be found on the drver s door B-pllar, see Techncal data ( page 416). ross Vehcle Weght Ratng (VWR): The total weght of the vehcle, all occupants, all cargo, and the traler tongue load ( page 310) must never exceed the VWR. ross Axle Weght Ratng (AWR): The total allowable weght that can be carred by a sngle axle (front or rear). To assure that your vehcle does not exceed the maxmum permssble weght lmts (VWR and AWR for front and rear axle), have the loaded vehcle (ncludng drver, passengers and all cargo and, f applcable, traler fully loaded) weghed on a sutable commercal scale. Traler tongue load The tongue load of any traler s an mportant weght to measure because t affects the load you can carry n your vehcle. If a traler s towed, the tongue load must be added to the weght of all occupants rdng and any cargo you are carryng n the vehcle. The tongue load typcally s ten percent of the traler weght and everythng loaded n t. Your Mercedes-Benz has been desgned prmarly to carry passengers and ther cargo. Mercedes-Benz does not recommend traler towng wth your vehcle. 310

312 Operaton Tres and wheels Recommended tre nflaton pressure Warnng! Follow recommended tre nflaton pressures. Do not undernflate tres. Undernflated tres wear excessvely and/or unevenly, adversely affect handlng and fuel economy, and are more lkely to fal from beng overheated. Do not overnflate tres. Overnflated tres can adversely affect handlng and rde comfort, wear unevenly, ncrease stoppng dstance, and result n sudden deflaton (blowout) because they are more lkely to become punctured or damaged by road debrs, potholes etc. Your vehcle s equpped wth ether the Tre and Loadng Informaton placard (Example A) or the Vehcle Tre Informaton placard (Example B) located on the drver s door B-pllar ( page 306). The tre nflaton pressure should be checked regularly and should only be adjusted on cold tres.

If the tre nflaton pressure repeatedly drops: Check the tres for punctures from foregn objects. Check to see whether ar s leakng from the valves or from around the rm. Tre temperature and tre nflaton pressure are also ncreased whle drvng, dependng on the drvng speed and the tre load. If you wll be drvng your vehcle at hgh speeds of 100 mph (160 km/h) or hgher, where t s legal and condtons allow, consult the placard on the nsde of the fuel fller flap on how to adjust the cold tre nflaton pressure. If you do not adjust the tre nflaton pressure, excessve heat can buld up and result n sudden tre falure. 312

314 Operaton Tres and wheels Be sure to readjust the tre nflaton pressure for normal drvng speeds. You should wat untl the tres are cold before adjustng the tre nflaton pressure. Some vehcles may have supplemental tre nflaton pressure nformaton for vehcle loads less than the maxmum loaded vehcle condton. If such nformaton s provded, t can be found on the placard located on the nsde of the fuel fller flap. Tre nflaton pressure changes by approxmately 1.5 ps (0.1 bar) per 18 F (10 C) of ar temperature change. Keep ths n mnd when checkng tre nflaton pressure where the temperature s dfferent from the outsde temperature. Checkng tre nflaton pressure Regularly check your tre nflaton pressure at least once a month. Check and adjust the tre nflaton pressure when the tres are cold. The tres can be consdered cold f the vehcle has been parked for at least three hours or drven less than one mle (1.6 km). If you check the tre nflaton pressure when the tres are warm (the vehcle has been drven for several mles or sttng less than three hours), the readng wll be approxmately 4 ps (0.3 bar) hgher than the cold readng. Ths s normal. Do not let ar out to match the specfed cold tre nflaton pressure. Otherwse, the tre wll be undernflated. Follow the steps below to acheve correct tre nflaton pressure: Remove the cap from the valve on one tre. Frmly press a tre gauge onto the valve. Read tre nflaton pressure on tre gauge and check aganst the recommended tre nflaton pressure on the placard on the drver s door B-pllar ( page 312).

Actual data on tres s specfc to each vehcle and may vary from data shown n above llustraton. Ths s the maxmum permssble tre nflaton pressure for the tre. Always follow the recommended tre nflaton pressure ( page 311) for proper tre nflaton. Warnng! Never exceed the max. tre nflaton pressure. Follow recommended tre nflaton pressures. Do not undernflate tres. Undernflated tres wear excessvely and/or unevenly, adversely affect handlng and fuel economy, and are more lkely to fal from beng overheated. Do not overnflate tres. Overnflated tres can adversely affect handlng and rde comfort, wear unevenly, ncrease stoppng dstance, and result n sudden deflaton (blowout) because they are more lkely to become punctured or damaged by road debrs, potholes etc. Unform Tre Qualty radng Standards (U.S. vehcles) Tre manufacturers are requred to grade tres based on three performance factors: treadwear, tracton and temperature resstance. 1 Treadwear 2 Tracton 3 Temperature resstance For llustraton purposes only. Actual data on tres s specfc to each vehcle and may vary from data shown n above llustraton. 322

324 Operaton Tres and wheels Qualty grades can be found, where applcable, on the tre sdewall between tread shoulder and maxmum secton wdth. For example: Treadwear Tracton Temperature 200 AA A All passenger car tres must conform to federal safety requrements n addton to these grades. Treadwear The treadwear grade s a comparatve ratng based on the wear rate of the tre when tested under controlled condtons on a specfed government test course. For example, a tre graded 150 would wear one and one-half (1 1 / 2 ) tmes as well on the government course as a tre graded 100. The relatve performance of tres depends upon the actual condtons of ther use, however, and may depart sgnfcantly from the norm due to varatons n drvng habts, servce practces and dfferences n road characterstcs and clmate. Tracton The tracton grades, from hghest to lowest, are AA, A, B, and C. Those grades represent the tre s ablty to stop on wet pavement as measured under controlled condtons on specfed government test surfaces of asphalt and concrete. A tre marked C may have poor tracton performance. Warnng! The tracton grade assgned to ths tre s based on straght-ahead brakng tracton tests, and does not nclude acceleraton, cornerng, hydroplanng, or peak tracton characterstcs. 323

325 Operaton Tres and wheels Temperature The temperature grades are A (the hghest), B, and C, representng the tre s resstance to the generaton of heat and ts ablty to dsspate heat when tested under controlled condtons on a specfed ndoor laboratory test wheel. Sustaned hgh temperature can cause the materal of the tre to degenerate and reduce tre lfe, and excessve temperature can lead to sudden tre falure. The grade C corresponds to a level of performance whch all passenger car tres must meet under the Federal Motor Vehcle Safety Standard No rades B and A represent hgher levels of performance on the laboratory test wheel than the mnmum requred by law. Warnng! The temperature grade for ths tre s establshed for a tre that s properly nflated and not overloaded. Excessve speed, undernflaton, or excessve loadng, ether separately or n combnaton, can cause excessve heat buld-up and possble tre falure.
