For nformaton on nfants and chldren travelng wth you n the vehcle and restrant systems for nfants and chldren, see Chldren n the vehcle ( page 70). The SRS system conducts a self-test when the gnton s swtched on and n regular ntervals whle the engne s runnng. Ths facltates early detecton of malfunctons. The 1 ndcator lamp n the nstrument cluster comes on when the gnton s swtched on and goes out no later than a few seconds after the engne has been started. The SRS components are n operatonal readness f the 1 ndcator lamp s not lt when the engne s runnng.

Safety and Securty Occupant safety Warnng! In the event that the 1 ndcator lamp comes on durng drvng or does not come on at all, the SRS self-check has detected a malfuncton. 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 deploy 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 repar 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. If t s necessary to modfy an ar bag system to accommodate a person wth dsabltes, contact your local authorzed Mercedes-Benz Center or call our Customer Assstance Center at 1-800-FOR-MERCedes (1-800-367-6372) for detals. 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 deployment 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. 61

Safety and Securty Occupant safety 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 ther respectve 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. Adjust the drver seat as far as possble rearward, stll permttng proper operaton of vehcle controls. 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 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 place ther bodes or lean ther heads n the area of the door or the rear sde trm panel where the sde mpact 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 use an approprately szed nfant or toddler restrant or booster seat recommended for the sze and weght of the chld. 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. Be sure to gve the buyer ths Operator s Manual. 62

Safety and Securty Occupant safety Warnng! Accdent research shows that the safest place for chldren n an automoble s n the rear seat. It should be noted that wth respect to both front and rear sde mpact ar bags there s a possblty for a sde mpact ar bag related njury f occupants, especally chldren, are not properly seated or restraned when next to a sde mpact ar bag whch needs to deploy rapdly n a sde mpact n order to do ts job. 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 or the rear sde trm panel where the sde mpact ar bag nflates. Ths could result n serous njures or death should the sde mpact ar bag be deployed. (2) Always st nearly uprght, properly use the seat belts and for chldren 12 years old and under, use an approprately szed nfant or toddler restrant or booster seat recommended for the sze and weght of the chld. (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 the rear mounted sde mpact 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 1-800-FOR-MERCedes (1-800-367-6372) for detals. Ar bags are desgned to deploy 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 events wll they provde ther supplemental protecton. The drver and passenger should always wear ther seat belts. Otherwse t s not possble for the ar bags to provde ther supplemental protecton. In case of other types of mpacts and mpacts below ar bag deployment thresholds, ar bags wll not deploy. The drver and passenger wll then be protected to the extent possble by a properly fastened seat belt. A properly fastened seat belt s also needed to provde the best possble protecton n a rollover. 63

Safety and Securty Occupant safety We cauton you not to rely on the presence of the ar bags n order to avod wearng your seat belt. It s mportant to your safety and that of your passengers that you replace deployed ar bags and repar any malfunctonng ar bags to make sure that the vehcle wll contnue to provde supplemental crash protecton for occupants. Safety gudelnes for the seat belt, emergency tensonng devce and ar bag Warnng! 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 belts nstalled or suppled by an authorzed Mercedes-Benz Center. Ar bags and emergency tensonng devces (ETDs) are desgned to functon on a one-tme-only bass. An ar bag or ETD that s deployed must be replaced. Do not pass belts over sharp edges. They could tear. Do not make any modfcaton that could change the effectveness of the belts. 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. No modfcatons of any knd may be made to any components or wrng of the SRS. Ths ncludes changng or removng any component or part of the SRS, the nstallaton of addtonal trm materal, badges, etc. over the steerng wheel hub, passenger front ar bag cover, door trm panels, or door frame trms, and nstallaton of addtonal electrcal/electronc equpment on or near SRS components and wrng. Keep area between ar bags and occupants free from objects (e.g. packages, purses, umbrellas, etc.). Do not hang tems such as coat hangers from the coat hooks or handles over the door. These tems may turn nto projectles and cause head and other njures when curtan ar bag s deployed. Ar bag system components wll be hot after an ar bag has nflated. Do not touch. 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. 64

Front ar bags 1 Drver ar bag 2 Passenger ar bag Drver and front passenger ar bags are deployed: n the event of certan frontal mpacts f mpact exceeds a preset deployment threshold ndependently of the sde mpact ar bags The front ar bags n ths vehcle have been desgned to nflate n two stages. Ths allows the ar bag to have dfferent rates of nflaton that are based on the rate of relevant vehcle deceleraton as assessed by the ar bag control unt. On the front passenger sde, the front ar bag deployment s addtonally nfluenced by the passenger s weght category as dentfed by the Occupant Classfcaton System (OCS) ( page 73). The lghter the front passenger sde occupant, the hgher the vehcle deceleraton rate requred for the second stage nflaton of the ar bag.

If the drver s seat belt s not fastened before the engne s started, the seat belt telltale < llumnates and a warnng chme sounds for approxmately sx seconds when the engne s started. The use of seat belts and nfant and chld restrant systems s requred by law n all 50 states, the Dstrct of Columba, the U.S. terrtores and all Canadan provnces. Even where ths s not the case, all vehcle occupants should have ther seat belts fastened whenever the vehcle s n moton. For more nformaton, see Fastenng the seat belts ( page 43). For nformaton on nfants and chldren travelng wth you n the vehcle and restrant systems for nfants and chldren, see Chldren n the vehcle ( page 70). Warnng! Always fasten your seat belt before drvng off. Always make sure all of 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. 67

Safety and Securty Occupant safety Warnng! Warnng! Warnng! 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. Make 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. Contact an authorzed Mercedes-Benz Center. 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. 68

Safety and Securty Occupant safety Never wear the shoulder belt under your arm, aganst your neck or off your shoulder. In a frontal 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 dstrbute 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. When usng a seat belt to secure nfant or toddler restrants or chldren n booster seats, always follow the chld seat manufacturer s nstructons. Emergency tensonng devce (ETD), seat belt force lmter The seat belts 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 60)! The ETDs for the front seats wll only actvate f the front seat belts are fastened (latch plate properly nserted nto buckle). The ETDs for the rear seats wll actvate wth or wthout the respectve seat belts fastened. 69

Safety and Securty Occupant safety In an mpact, emergency tensonng devces remove slack from the belts. 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 dsposng of the emergency tensonng devce, our safety nstructons must be followed. These are avalable at your authorzed Mercedes-Benz Center. Automatc comfort-ft feature seat belt An automatc comfort-ft feature for front seats reduces the retractng force of the seat belts when they are n normal use.

Safety and Securty 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) In wnter operaton, the maxmum effectveness of the ABS, the BAS, and the ESP 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, and ESP cannot reduce ths rsk. Always adjust your drvng style to the prevalng road and weather condtons. ABS Warnng! 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 gnton. It goes out when the engne s runnng. 84

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 the 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 353). 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. 85

Safety and Securty Drvng safety systems Warnng! The BAS cannot prevent the natural laws of physcs from actng on the vehcle, nor can t ncrease brakng effcency beyond that afforded by the condton of the vehcle brakes and tres or the tracton. The BAS 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 a BAS 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 353). 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 nstrument cluster flashes when the ESP s engaged. The warnng lamp v n the nstrument cluster 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 nstrument cluster. In ths case, proceed as follows: Whle drvng off, apply as lttle throttle as possble. Whle drvng, ease upon 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. 86

Safety and Securty Drvng safety systems Warnng! The ESP cannot prevent the natural laws of physcs from actng on the vehcle, nor can t ncrease the tracton afforded. The ESP cannot prevent accdents, ncludng those resultng from excessve speed n turns or hydroplanng. Only a safe, attentve, and skllful drver can prevent accdents. The capabltes of an ESP equpped vehcle must never be exploted n a reckless or dangerous manner whch could jeopardze the user s safety or the safety of others.! Because of the ESP s automatc operaton, the engne must be shut off when the parkng brake s beng tested on a brake test dynamometer the vehcle s beng towed wth the front axle rased Actve brakng acton through the ESP may otherwse serously damage the brake system. The ESP wll only functon properly f you use wheels of the recommended tre sze. For more nformaton, see Practcal hnts ( page 353). Swtchng off the ESP To mprove the vehcle s tracton, turn off the ESP n drvng stuatons where t would be advantageous to have the drve wheels spn and thus cut nto surfaces for better grp such as: Warnng! startng out on slppery surfaces and n deep snow n conjuncton wth snow chans sand or gravel The ESP should not be swtched off durng normal drvng other than n the crcumstances descrbed below. Dsablng of the system wll reduce vehcle stablty n standard drvng maneuvers.! Turn on the ESP mmedately f the aforementoned crcumstances do not apply anymore. 87

Operaton The frst 1000 mles (1500 km) In the Operaton secton you wll fnd detaled nformaton on operatng, mantanng and carng for your vehcle. The more cautously you treat your vehcle durng the break-n perod, the more satsfed you wll be wth ts performance later on. Drve your vehcle durng the frst 1000 mles (1500 km) at varyng but moderate vehcle and engne speeds. Durng ths perod, avod heavy loads (full throttle drvng) and excessve engne speeds (no more than 2 / 3 of maxmum rpm n each gear). Shft gears n a tmely manner. Avod acceleratng by kckdown. Do not attempt to slow the vehcle down by shftng to a lower gear usng the gear selector lever. Select postons 3, 2 or 1 only when drvng at moderate speeds (for hll drvng). Select mode C as the preferred shft program ( page 170) for the frst 1000 mles (1500 km). After 1000 mles (1500 km), you may gradually ncrease vehcle and engne speeds to the permssble maxmum.! Addtonal nstructons for AM vehcles: Durng the frst 1000 mles (1500 km), do not exceed a speed of 85 mph (140 km/h). Durng ths perod, avod engne speeds above 4500 rpm n each gear. All of the above nstructons, as may apply to your vehcle type, also apply when drvng the frst 1000 mles (1500 km) after the engne or the rear dfferental has been replaced. Always obey applcable speed lmts. 294

Drvng nstructons Drve sensbly save fuel Drnkng and drvng Pedals Operaton Drvng nstructons Fuel consumpton, to a great extent, depends on drvng habts and operatng condtons. To save fuel you should: Keep tres at the recommended nflaton pressures. Remove unnecessary loads. Remove roof rack when not n use. Allow engne to warm up under low load use. Avod frequent acceleraton and deceleraton. Have all mantenance work performed at the ntervals specfed n the Mantenance Booklet and as requred by the Mantenance System (U.S. vehcles) or FSS (Canada vehcles). Contact an authorzed Mercedes-Benz Center. Fuel consumpton s also ncreased by drvng n cold weather, n stop-and-go traffc, on short trps and n hlly area. Warnng! Drnkng and drvng and/or takng drugs and drvng are very dangerous combnatons. Even a small amount of alcohol or drugs can affect your reflexes, perceptons and judgement. 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. 295

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 85). 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. 296

Operaton Drvng nstructons 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.! 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 can 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 gradually. 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 wear and drvetran wear. Parkng! Set the parkng brake whenever parkng or leavng the vehcle. In addton, move gear selector lever to poston P. When parkng on hlls, 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. 297

Operaton Drvng nstructons Warnng! To reduce the rsk of personal njury as a result of nadvertent vehcle movement, before turnng off the engne and leavng the vehcle always: Keep rght foot frmly on brake pedal. Frmly depress parkng brake pedal. Move the gear selector lever to poston P. 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, or press KEYLESS-O* start/stop button (vehcles wth KEYLESS-O*). Take the SmartKey or the SmartKey wth KEYLESS-O* wth you and lock the vehcle when leavng. 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. 298

Operaton Drvng nstructons Specfed tre nflaton pressures must be mantaned. Ths apples partcularly f the tres are subject to extreme operatng condtons (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. 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. 299

Operaton Drvng nstructons 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. CLK 320 wth Appearance Package Your vehcle s factory equpped wth W -rated tres, whch have a speed ratng of 168 mph (270 km/h). An electronc speed lmter prevents your vehcle from exceedng a speed of 130 mph (210 km/h). CLK 500 Your vehcle s factory equpped wth Y -rated tres, whch have a speed ratng of 186 mph (300 km/h). An electronc speed lmter prevents your vehcle from exceedng a speed of 130 mph (210 km/h). CLK 55 AM Your vehcle s factory equpped wth Y -rated tres, whch have a speed ratng of 186 mph (300 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 342). For addtonal general nformaton on tre speed markngs on tre sdewall, see Tre speed ratng ( page 331). 300

Operaton Drvng nstructons 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. Try to keep the vehcle under control by correctve steerng acton. For nformaton on drvng wth snow chans, see Snow chans ( page 343). 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. 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 342). 301

Operaton Drvng nstructons 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. 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. 302

Operaton Drvng nstructons Telephones* and two-way rados 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.

Keep your vehcle n proper from nsde the vehcle whle the engne s operatng condton by followng our runnng. Dong so could lead to a malfuncton of the vehcle s electronc system, pos- recommended mantenance nstructons as outlned n your Mantenance Booklet. sbly resultng n an accdent and/or serous personal njury.! 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. 303

Operaton Drvng nstructons 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 to 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. Warnng! Coolant temperature 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 wth at least one wndow fully open at all tmes. 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. 304

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! 316 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. See an authorzed Mercedes-Benz Center for nformaton on tested and recommended rms and tres for summer and wnter operaton. 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).

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 325). Tre nspecton Every tme you check your tre nflaton pressure, you should also nspect your tres for the followng: excessve tread wear ( page 318) 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. 317

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). Tread wear 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 tread wear 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 (Tread Wear Indcator) The tread wear 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. 318

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.

Operaton Tres and wheels Steps for determnng correct load lmt The followng steps have been developed as requred of all manufacturers under Ttle 49, Code of U.S. Federal Regulatons, Part 575 pursuant to the Natonal Traffc and Motor Vehcle Safety Act of 1966. Step 1 (Vehcles equpped wth placard Example A) Locate the statement The combned weght of occupants and cargo should never exceed XXX kg or XXX lbs. on your vehcle s placard. 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. (1400-750 (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 324). 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. Ths s for llustraton purposes only. Make sure you are usng the actual load lmt for your vehcle stated on the vehcle s placard ( page 320). 322

Operaton Tres and wheels Certfcaton label Even after careful determnaton of the combned weght of all occupants, cargo and the traler tongue load (f applcable) ( page 324) as to not exceed the permssble load lmt, you must make sure that your vehcle never exceeds the ross Vehcle Weght Ratng (VWR) and the ross Axle Weght Ratng (AWR) for ether the front or rear axle. 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 436). ross Vehcle Weght Ratng (VWR): The total weght of the vehcle, all occupants, all cargo, and the traler tongue load ( page 324) 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. 324

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 320). The tre nflaton pressure should be checked regularly and should only be adjusted on cold tres. 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). Follow recommended cold tre nflaton pressures lsted on placard. Keepng the tres properly nflated provdes the best handlng, tread lfe and rdng comfort. In addton to the tre placard on the drver s door B-pllar, also consult the fuel fller flap for any addtonal nformaton pertanng to specal drvng stuatons.

Important notes on tre nflaton pressure Warnng! 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. 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 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. 326

Operaton Tres and wheels 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. Checkng tre nflaton pressure manually Follow the steps below to acheve correct tre nflaton pressure: 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 325). If necessary, add ar to acheve the recommended tre nflaton pressure. If you have overflled the tre, release tre nflaton pressure by pushng the metal stem of the valve wth e.g. a tp of a pen. Then recheck the tre nflaton pressure wth the tre gauge. Install the valve cap. Repeat ths procedure for each tre.

Operaton Tres and wheels 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. 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. 336

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. 109. 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. Tre ply materal 1 Ples n sdewall 2 Ples under tread For llustraton purposes only. Actual data on tres s specfc to each vehcle and may vary from data shown n above llustraton.

Operaton Tres and wheels Rotatng tres Warnng! Rotate front and rear wheels only f the tres are of the same dmenson. If your vehcle s equpped wth mxed-sze tres (dfferent tre dmensons front vs. rear), tre rotaton s not possble. Tre rotaton can be performed on vehcles wth tres of the same dmenson all around. If your vehcle s equpped wth tres of the same dmenson all around, tres can be rotated, observng a a front-to-rear rotaton pattern that wll mantan the ntended rotaton (spnnng) drecton of the tre ( page 319). In some cases, such as when your vehcle s equpped wth mxed-sze tres (dfferent tre dmenson front vs. rear), tre rotaton s not possble. If applcable to your vehcle s tre confguraton, tres can be rotated accordng to the tre manufacturer s recommended ntervals n the tre manufacturer s warranty pamphlet located n your vehcle lterature portfolo. If none s avalable, tres should be rotated every 3000 to 6000 mles (5000 to 10000 km), or sooner f necessary, accordng to the degree of tre wear. The same rotaton (spnnng) drecton must be mantaned ( page 319). Rotate tres before the characterstc tre wear pattern becomes vsble (shoulder wear on front tres and tread center wear on rear tres). Thoroughly clean the mountng face of wheels and brake dsks,.e. the nner sde of the wheels/tres, durng each rotaton. Check for and ensure proper tre nflaton pressure. Warnng! Have the tghtenng torque checked after changng a wheel. Wheels could become loose f not tghtened wth a torque of 80 lb-ft (110 Nm).

Vehcle care Cleanng and care of vehcle Warnng! Many cleanng products can be hazardous. Some are posonous, others are flammable. Always follow the nstructons on the partcular contaner. Always open your vehcle s doors or wndows when cleanng the nsde. Never use fluds or solvents that are not desgned for cleanng your vehcle. Whle n operaton, even whle parked, your vehcle s subjected to varyng external nfluences whch, f gone unchecked, can attack the pantwork as well as the underbody and cause lastng damage. Such damage s caused not only by extreme and varyng clmatc condtons, but also by: Ar polluton Road salt Tar ravel and stone chppng To avod pant damage, you should mmedately remove: rease and ol Fuel Coolant Brake flud Brd droppngs Insects Tree resns, etc. Frequent washng reduces and/or elmnates the aggressveness and potency of the above adverse nfluences. Operaton Vehcle care More frequent washngs are necessary to deal wth unfavorable condtons: near the ocean n ndustral areas (smoke, exhaust emssons) durng wnter operaton You should check your vehcle from tme to tme for stone chppng or other damage. Any damage should be repared as soon as possble to prevent corroson. In dong so, do not neglect the underbody of the vehcle. A prerequste for a thorough check s a washng of the underbody followed by a thorough nspecton. Damaged areas need to be re-undercoated. Your vehcle has been treated at the factory wth a wax-base rustproofng n the body cavtes whch wll last for the lfetme of the vehcle. Post-producton treatment s nether necessary nor recommended by Mercedes-Benz because of the possblty of ncompatblty between materals used n the producton process and others appled later. 347

Brake flud Durng vehcle operaton, the bolng pont of the brake flud s contnuously reduced through the absorpton of mosture from the atmosphere. Under extremely strenuous operatng condtons, ths mosture content can lead to the formaton of bubbles n the system, thus reducng the system s effcency. Therefore, the brake flud must be replaced every two years, preferably n the sprng. Only brake flud approved by Mercedes-Benz s recommended. Your authorzed Mercedes-Benz Center wll provde you wth addtonal nformaton. Premum unleaded gasolne! To mantan the engne s durablty and performance, premum unleaded gasolne must be used. If premum unleaded s not avalable and low octane fuel s used, follow these precautons: Have the fuel tank only partally flled wth unleaded regular and fll up wth premum unleaded as soon as possble. Avod full throttle drvng and abrupt acceleraton. Do not exceed an engne speed of 3000 rpm f the vehcle s loaded wth a lght load such as two persons and no luggage. Do not exceed 2 / 3 of maxmum accelerator pedal poston f the vehcle s fully loaded or operatng n mountanous terran. 450

Techncal data Fuels, coolants, lubrcants, etc. Fuel requrements Only use premum unleaded fuel: The octane number (posted at the pump) must be 91 mn. It s an average of both the Research (R) octane number and the Motor (M) octane number: (R+M)/2). Ths s also known as the ANTI-KNOCK INDEX. Unleaded gasolne contanng oxygenates such as ethanol, IPA, IBA and TBA can be used provded the rato of any one of these oxygenates to gasolne does not exceed 10%; MTBE not to exceed 15%. The rato of methanol to gasolne must not exceed 3% plus addtonal cosolvents. Usng mxtures of ethanol and methanol s not allowed. asohol, whch contans 10% ethanol and 90% unleaded gasolne, can be used. These blends must also meet all other fuel requrements, such as resstance to spark knock, bolng range, vapor pressure, etc. asolne addtves A major concern among engne manufacturers s carbon buld-up caused by gasolne. Mercedes-Benz recommends only the use of qualty gasolne contanng addtves that prevent the buld-up of carbon deposts. After an extended perod of usng fuels wthout such addtves, carbon deposts can buld up especally on the ntake valves and n the combuston area, leadng to engne performance problems such as: Warm-up hestaton Unstable dle Knockng/pngng Msfre Power loss In areas where carbon deposts may be encountered due to lack of avalablty of gasolnes whch contan these addtves, Mercedes-Benz recommends the use of addtves approved by us for use on Mercedes-Benz vehcles. Refer to Factory Approved Servce Products pamphlet for a lstng of approved product(s). Follow drectons on product label. Do not blend any specfc fuel addtves wth fuel. Ths only results n unnecessary cost and may be harmful to the engne operaton. Damage or malfuncton resultng from poor fuel qualty or from blendng addtonal fuel addtves other than those tested and approved by us for use on Mercedes-Benz vehcles lsted n the Factory Approved Servce Products pamphlet are not covered by the Mercedes-Benz Lmted Warranty. 451

Techncal data Fuels, coolants, lubrcants, etc. Coolants The engne coolant s a mxture of water and antcorroson/antfreeze, whch provdes: Corroson protecton Freeze protecton Bolng protecton (by ncreasng the bolng pont) The coolng system was flled at the factory wth a coolant provdng freeze protecton to approxmately -22 F (-30 C) and corroson protecton. If the antfreeze mxture s effectve to -22 F (-30 C), the bolng pont of the coolant n the pressurzed coolng system s reached at approx. 266 F (130 C). The coolant soluton must be used year-round to provde the necessary corroson protecton and ncrease bol-over protecton. Refer to Mantenance Booklet for replacement nterval. Coolant system desgn and coolant used determne the replacement nterval. The replacement nterval publshed n the Mantenance Booklet s only applcable f MB 325.0 antcorroson/antfreeze soluton or other Mercedes-Benz approved products of equal specfcaton (see Factory Approved Servce Products pamphlet) are used to renew the coolant concentraton or brng t back up to the proper level. To provde mportant corroson protecton, the soluton must be at least 45% antcorroson/antfreeze (equvalent to freeze protecton to approx. -22 F [-30 C]). If you use a soluton that s more than 55% antcorroson/antfreeze (freeze protecton to approx. -49 F [-45 C]), the engne temperature wll ncrease due to the lower heat transfer capablty of the soluton. Therefore, do not use more than ths amount of antcorroson/antfreeze. If the coolant level s low, water and MB Antcorroson/Antfreeze should be used to brng t up to the proper level (have coolng system checked for sgns of leakage). Please make sure the mxture s n accordance wth label nstructons. The water n the coolng system must meet mnmum requrements, whch are usually satsfed by normal drnkng water. If you are not sure about the water qualty, consult an authorzed Mercedes-Benz Center. 452
