case, the brake system functions in the usual manner, but without antilock assistance. A malfunctioning ABS control unit can possibly affect the operation of other systems (e.g. Navigation, Automatic transmission). Be guided accordingly with respect to the use of those systems and have the system checked at your authorized Mercedes-Benz Center as soon as possible. With the ABS malfunctioning, the BAS and ESP are also switched off. The malfunction indicator lamps and malfunction messages in the multifunction display come on with the engine running. If the charging voltage falls below 10 volts, the malfunction indicator lamp comes on and the ABS is switched off. When the voltage is above this value again, the malfunction indicator lamp should go out and the ABS is operational. Have the system checked at your authorized Mercedes-Benz Center as soon as possible. See page 272 for notes on antilock brake system (ABS).

It should go out with engine running. If the ESP malfunction indicator lamp remains illuminated with the engine running, a malfunction has been detected in the system. Pressing the accelerator pedal will require greater effort. Only partial engine output will be available. See electronic stability program (ESP) on page 274 if the warning lamp lights up or flashes when the vehicle is moving. With the electronic key in starter switch position 2, the seat belt nonusage warning lamp comes on, and a warning sounds for a short time if the drivers seat belt is not fastened. After starting the engine, the seat belt nonusage warning lamp blinks for a brief period to remind the driver and passengers to fasten seat belts. Malfunction and indicator lamp in the center console AIRBAG OFF indicator lamp The ü indicator lamp will light up for approximately 6 seconds when you turn the electronic key in starter switch to position 1 or 2. It does not light up if there is a fault in the system. The ü indicator lamp stays lit as long as a Baby SmartTM child seat is properly installed on the front passenger seat. It indicates that the front passenger airbag is switched off. See page 69 for BabySmartTM airbag and its deactivation system. Warning! The BabySmartTM airbag deactivation system will ONLY work with a special child seat designed to operate with it. It will not work with child seats which are not BabySmartTM compatible. Never place anything between seat cushion and child seat (e.g. pillow), since it reduces the effectiveness of the deactivation system. Follow the manufacturer’s instructions for installation of special child seats. The passenger front airbag will not deploy only if the ü indicator lamp remains illuminated. Please be sure to check the indicator every time you use the special system child seat. Should the light go out while the restraint is installed, please check installation. If the light remains out, do not use the BabySmartTM restraint to transport children on the front passenger seat until the system has been repaired.

Engine compartment 317 Instruments and controls Operation Driving Instrument cluster display Practical hints Car care Technical data Index Instruments and controls Operation Driving Instrument cluster display Practical hints Car care Technical data Index Engine compartment Adding engine oil 318 1 Oil dipstick 2 Oil filler cap To check the engine oil level, park vehicle on level ground, with engine at normal operational temperature. Check engine oil level approximately 5 minutes after stopping the engine, allowing for the oil to return to the oil pan. The engine oil level can be checked by either the oil dipstick or via the multifunction display in the instrument cluster. Wipe oil dipstick clean prior to checking the engine oil level. Fully insert dipstick in tube, and remove after three seconds to obtain accurate reading. The oil level must be between the lower mark (min) and the upper mark (max) on the oil dipstick. Fill quantity between upper and lower dipstick marking level is approximately 2.1 US qt (2.0 l). Do not overfill the engine. Excessive oil must be drained or siphoned. It could cause damage to engine and catalytic converter not covered by the Mercedes-Benz Limited Warranty. See malfunction and warning messages on page 290 if an engine oil level display appears on the multifunction display when the engine is running. Note: See page 141 for engine oil level indicator display. Coolant level 1 Coolant expansion tank To check the coolant level, the vehicle must be parked on level ground and the engine stopped. Check coolant level only when coolant is cold. The coolant level should reach the black top part of the reservoir. See page 381 for antifreeze/anticorrosion mixture. Adding coolant If coolant has to be added, a 50/50 mixture of water and MB anticorrosion/antifreeze should be added. Warning! • In order to avoid possibly serious burns: Use extreme caution when opening the hood if there are any signs of steam or coolant leaking from the cooling system, or if the coolant temperature gauge indicates that the coolant is overheated. • Do not remove pressure cap on coolant reservoir if engine temperature is above 194°F (90°C). Allow engine to cool down before removing cap. The coolant reservoir contains hot fluid and is under pressure. • Using a rag, slowly open cap approximately 1/2 turn to relieve excess pressure. If opened immediately, scalding hot fluid and steam will be blown out under pressure. • Do not spill antifreeze on hot engine parts. Antifreeze contains ethylene glycol which may burn if it comes into contact with hot engine parts.

The jack is designed exclusively for jacking up the vehicle at the jack take-up brackets built into either side of the vehicle. To help avoid personal injury, use the jack only to lift the vehicle during a wheel change. Never get beneath the vehicle while it is supported by the jack. Keep hands and feet away from the area under the lifted vehicle. Always firmly set parking brake and block wheels before raising vehicle with jack. Do not disengage parking brake while the vehicle is raised. Be certain that the jack is always vertical when in use, especially on hills. Always try to use the jack on level surface. Be sure that the jack arm is fully seated in the jack take-up bracket. Always lower the vehicle onto sufficient capacity jackstands before working under the vehicle. 324 Wheels Replace rims or tires with the same designation, manufacturer and type as shown on the original part. See your authorized Mercedes-Benz Center for further information. See your authorized Mercedes-Benz Center for information on tested and recommended rims and tires for summer and winter operation. They can also offer advice concerning tire service and purchase. Tire replacement Front and rear tires should be replaced in sets. Rims and tires must be of the correct size and type. For dimensions, see “Technical Data”. We recommend that you break in new tires for approximately 60 miles (100 km) at moderate speed. It is imperative that the wheel mounting bolts be fastened to a tightening torque of 80 ft.lb. (110 Nm) whenever wheels are mounted. For rim and tire specifications, refer to “Technical Data”. Warning! Worn, old tires can cause accidents. If the tire tread is badly worn, or if the tires have sustained damage, replace them. When replacing rims, use only genuine Mercedes-Benz wheel bolts specified for the particular rim type. Failure to do so can result in the bolts loosening and possibly an accident. Rotating wheels The wheels can be rotated according to the degree of tire wear while retaining the same direction of travel. Rotating, however, should be carried out as recommended by the tire manufacturer, before the characteristic tire wear pattern (shoulder wear on front wheels and tread center wear on rear wheels) becomes visible, as otherwise the driving properties deteriorate. Notes: Thoroughly clean the inner side of the wheels any time you rotate the wheels or wash the vehicle underside. The use of retread tires is not recommended. Retread tires may adversely affect the handling characteristics and safety of the vehicle. Dented or bent rims can cause tire pressure loss and damage to the tire beads. For this reason, check rims for damage at regular intervals. The rim flanges must be checked for wear before a tire is mounted. Remove burrs, if any. Check and ensure proper tire inflation pressure after rotating the wheels. For tire inflation pressure see inside of fuel filler flap and also page 278.

The spare wheel rim size is 4 1/2 B x 15 H 2 with inflatable, collapsible tire, size 165-15 89 P. You should inflate the spare tire using the supplied air pump. Warning! The dimensions of the spare wheel are different from those of the road wheels. As a result, the vehicle handling characteristics change when driving with a mounted spare wheel. The spare wheel should only be used temporarily, and replaced with a regular road wheel as quick as possible. In the case of a flat tire, you may temporarily use the spare wheel, while observing the following restrictions: • Do not exceed vehicle speed of 50 mph (80 km/h). • Drive to the nearest tire repair facility to have the flat tire repaired or replaced as appropriate. • Do not operate vehicle with more than one collapsible spare wheel/tire mounted. For additional information, refer to page 374. Changing wheels Warning! The jack is designed exclusively for jacking up the vehicle at the jack take-up brackets built into either side of the vehicle. To help avoid personal injury, use the jack only to lift the vehicle during a wheel change. Never get beneath the vehicle while it is supported by the jack. Keep hands and feet away from the area under the lifted vehicle. Always firmly set parking brake and block wheels before raising vehicle with jack. Do not disengage parking brake while the vehicle is raised. Be certain that the jack is always vertical when in use, especially on hills. Always try to use the jack on level surface. Be sure that the jack arm is fully seated in the jack take-up bracket. Always lower the vehicle onto sufficient capacity jackstands before working under the vehicle. Move vehicle to a level area which is a safe distance from the roadway. 1. Set parking brake and turn on hazard warning
