This may indicate that the poly-V-belt has broken. Should this
condition occur, the poly-V-belt must be replaced before continuing to operate the vehicle. Otherwise, the engine will overheat due to an inoperative water pump which may result in damage to the engine. Do not continue to drive the vehicle with this message displayed. Doing so could result in serious engine damage that is not covered by the Mercedes-Benz Limited Warranty.
During severe operating conditions and stop-and-go city traffic, the coolant temperature may rise close to the red marking. The engine should not be operated with the coolant temperature in the red zone. Doing so may cause serious engine damage which is not covered by the Mercedes-Benz Limited Warranty.
Warning! Driving when your engine is badly overheated can cause some fluids which may have leaked into the engine compartment to catch fire. You could be seriously burned. Steam from an overheated engine can cause serious burns and can occur just by opening the engine hood. Stay away from the engine if you see or hear steam coming from it. Turn off the engine, get out of the vehicle and do not stand near the vehicle until it cools down.

Coolant level
Automatic transmission fluid level The transmission has a permanent fill of automatic transmission fluid. Regular automatic transmission fluid level checks and changes are not required. For this reason the dipstick is omitted. If you notice fluid leaks or gear shifting malfunctions, have your authorized Mercedes-Benz Center check the transmission fluid level.
P20.30-2032-26
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.
236
Adding coolant If coolant has to be added, a 50/50 mixture of water and MB anticorrosion/antifreeze should be added. The drain plugs for the cooling system are located on the right side of the engine block and at the bottom of the radiator. Anticorrosion/antifreeze mixture, see page 287.
Warning! In order to avoid possible serious burns or injury:
• 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.

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 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 approx. 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.
239
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.
Important! Unidirectional tires must always be mounted with arrow on tire sidewall pointing in direction of vehicle forward movement.
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 247.

Spare wheel
Important! The spare wheel rim size is 71/2 J x 17 H 2. The spare wheel rim is mounted with a full size tire of the same type as on the vehicle’s front axle, and is fully functional. However, that spare wheel rim is weight optimized and has a limited service life of 12 000 miles (20 000 km) use before a standard wheel rim must replace it. In the case of a rear axle flat tire, you may temporarily use the spare wheel, when 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 spare
wheel mounted.
If the arrow on tire side wall does not point in direction of vehicle forward movement when using the spare wheel, observe the following restriction:
Unidirectional tires must always be mounted with arrow on tire sidewall pointing in direction of vehicle forward movement. For rim and tire specifications, refer to “Technical Data”.
Warning! The spare wheel rim is for temporary use only. Use for over a total of 12 000 miles (20 000 km) (aggregate of all uses) may cause wheel rim failure leading to an accident and possible injuries. The dimensions of the spare wheel are different from those of the road wheels of the rear axle. As a result, the vehicle handling characteristics change when driving with a spare wheel mounted on the rear axle. The spare wheel should only be used temporarily, and replaced with a regular road wheel as quick as possible.

Warning! Always replace wheel bolts that are damaged or rusted. Never apply oil or grease to wheel bolts. Damaged wheel hub threads should be repaired immediately. Incorrect mounting bolts or improperly tightened mounting bolts can cause the wheel to come off. This could cause an accident. Be sure to use the correct mounting bolts.
Warning! The spare wheel rim is for temporary use only. Use for over a total of 12 000 miles (20 000 km) (aggregate of all uses) may cause wheel rim failure leading to an accident and possible injuries. The dimensions of the spare wheel are different from those of the road wheels of the rear axle. As a result, the vehicle handling characteristics change when driving with a spare wheel mounted on the rear axle. The spare wheel should only be used temporarily, and replaced with a regular road wheel as quick as possible.
246
Tire inflation pressure A table (see fuel filler flap) lists the tire inflation pressures specified for Mercedes-Benz recommended tires as well as for the varying operating conditions.
Important! Tire pressure changes by approx. 1.5 psi (0.1 bar) per 18°F (10°C) of air temperature change. Keep this in mind when checking tire pressure inside a garage – especially in the winter. Example: If garage temperature = approx. +68°F (+20°C) and ambient temperature = approx. +32°F (0°C) then the adjusted air pressure = specified air pressure +3 psi (+0.2 bar).
Tire pressures listed for light loads are minimum values offering high driving comfort. Increased inflation pressures for heavy loads produce favorable handling characteristics with lighter loads and are perfectly permissible. The ride of the vehicle, however, will become somewhat harder. Tire temperature and pressure increase with the vehicle speed. Tire pressure should therefore only be checked and corrected on cold tires. Correct tire pressure in warm tires only if pressure has dropped below the pressure listed in the table and the respective operating conditions are taken into consideration. An underinflated tire due to a slow leak (e.g. due to a nail in the tire) may cause damage such as tread separation, bulging etc.. Regular tire pressure checks (including the spare tire) at intervals of no more than 14 days are therefore essential.

If a tire constantly loses air, it should be inspected for damage. The spare tire should be checked periodically for condition and inflation. Spare tire will age and become worn over time even if never used, and thus should be inspected and replaced when necessary.
Warning! Do not overinflate tires. Overinflating tires can result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes etc.. Follow recommended inflation pressures. Do not overload the tires by exceeding the specified vehicle capacity weight (as indicated by the label on the driver’s door latch post). Overloading the tires can overheat them, possibly causing a blowout.

Warning! Failure to follow these instructions can result in severe injury or death. Never lean over batteries while connecting, you might get injured. Battery fluid contains sulfuric acid. Do not allow this fluid to come in contact with eyes, skin or clothing. In case it does, immediately flush affected area with water and seek medical help if necessary. A battery will also produce hydrogen gas, which is flammable and explosive. Keep flames or sparks away from battery, avoid improper connection of jumper cables, smoking etc..
Important! Battery replacement information: The maintenance-free battery is located in the trunk under the trunk floor. The service life of the battery is dependent on its condition of charge. The battery should always be kept sufficiently charged, in order to last an optimum length of time.
Therefore, we strongly recommend that you have the battery charge checked frequently, and corrected if necessary, especially if you use the vehicle less than approximately 200 miles (300 km) per month, mostly for short distance trips, or if it is not used for long periods of time. Only charge a battery with a battery charger after the battery has been disconnected from the vehicle’s electrical circuit. Always disconnect the battery negative lead first and connect last. When removing and connecting the battery, always make sure that all electrical consumers are off and the electronic key is in steering lock position 0. The battery and its filler caps must always be securely installed when the vehicle is in operation. During removal and installation always protect the disconnected battery positive (+) terminal with the cover attached to the battery. While the engine is running the battery terminal clamps must not be loosened or detached, otherwise the generator and other electronic components would be damaged.
249
Notes: After reconnecting the battery also resynchronize the front seats, the express feature of the power windows (see page 142), and the electronic stability program (ESP) (see page 201).
front seat head restraints (see page 49),
Battery recycling Batteries contain material that can harm the environment with improper disposal. Large 12 Volt storage batteries contain lead. Recycling of batteries is the preferred method of disposal. Many states require sellers of batteries to accept old batteries for recycling.

Keep flames or sparks away from battery, avoid improper connection of jumper cables, smoking etc.. Read all instructions before proceeding.
If the battery is discharged, the engine should be started with jumper cables and the (12 V) battery of another vehicle. Only use 12 V battery to jump start your vehicle. Jump starting with more powerful battery could damage the vehicle’s electrical systems, which will not be covered by the Mercedes-Benz Limited Warranty. The battery is located in the trunk under the trunk floor.
Proceed as follows:
1. Position the vehicle with the charged battery so that
the jumper cables will reach, but never let the vehicles touch. Make sure the jumper cables do not have loose or missing insulation.
2. On both vehicles:
• Turn off engine and all lights and accessories, except hazard warning flashers or work lights. • Apply parking brake and shift selector lever to
position “P”.
251
Important!
3. Clamp one end of the first jumper cable to the
positive (+) under hood terminal of the discharged battery and the other end to the positive (+) terminal of the charged battery. Make sure the cable clamps do not touch any other metal parts.
4. Clamp one end of the second jumper cable to the
grounded negative (–) terminal of the charged battery and the final connection to the negative (–) terminal (2) of the discharged battery.
Important!
5. Start engine of the vehicle with the charged battery
and run at high idle. Make sure the cables are not on or near pulleys, fans, or other parts that move when the engine is started. Allow the discharged battery to charge for a few minutes. Start engine of the disabled vehicle in the usual manner.
6. After the engine has started, remove jumper cables
by exactly reversing the above installation sequence, starting with the last connection made first. When removing each clamp, make sure that it does not touch any other metal while the other end is still attached.
Important! A discharged battery can freeze at approx. +14°F (–10°C). In that case, it must be thawed out before jumper cables are used. Attempting to jump start a frozen battery can result in it exploding, causing personal injury. Jumper cable specifications: • Minimum cable cross-section of 25 mm2 or approx.
2 AWG
• Maximum length of 11.5 ft. (3.5 m).
Notes: If engine does not run after several unsuccessful starting attempts, have it checked at the nearest authorized Mercedes-Benz Center. Excessive unburned fuel may damage the catalytic converter.

Towing the vehicle
Prior to towing the vehicle with all wheels on the ground, make certain that the electronic key is in steering lock position 2. If the electronic key is left in the steering lock position 0 for an extended period of time, it can no longer be turned in the lock. In this case, the steering is locked. To unlock, remove electronic key from steering lock and reinsert.
Important! When towing the vehicle, please, note the following: With the automatic central locking activated and the electronic key in steering lock position 2, the vehicle doors lock if the left front wheel as well as the right rear wheel are turning at vehicle speeds of approx. 9 mph (15 km/h) or more. To prevent the vehicle door locks from locking, deactivate the automatic central locking, see page 36.
P88.20-2026-26
The rear towing eye is located at the right, below the bumper. The front towing eye is located on the passenger side behind a cover in the bumper panel.
Cover removal: Insert finger in recess of cover and pull cover out. Cover installation: Engage cover at bottom and press in top securely.
253
Note: To signal turns while being towed with hazard warning flasher in use, turn electronic key in steering lock to position 2 and activate combination switch for left or right turn signal in usual manner – only the selected turn signal will operate. Upon canceling the turn signal, the hazard warning flasher will operate again.
Caution! If the vehicle is towed with the front axle raised, the engine must be shut off (electronic key in steering lock position 0 or 1). Otherwise, the ESP will immediately be engaged and will apply the rear wheel brakes. Switch off the tow-away alarm as well as the ESP.
We recommend that the vehicle be transported using flat bed equipment. This method is preferable to other types of towing. The vehicle may be towed with all wheels on the ground and the selector lever in position “N” for distances up to 30 miles (50 km) and at a speed not to exceed 30 mph (50 km/h). The electronic key must be in steering lock position 2. To be certain to avoid a possibility of damage to the transmission, however, we recommend the drive shaft be disconnected at the rear axle drive flange for any towing beyond a short tow to a nearby garage. Do not tow with sling-type equipment. Towing with sling-type equipment over bumpy roads will damage radiator and supports. Use wheel lift, dolly, or flat bed equipment, with electronic key in steering lock turned to position 0.
Warning! With the engine not running, there is no power assistance for the braking and steering systems. In this case, it is important to keep in mind that a considerably higher degree of effort is necessary to brake and steer the vehicle.

Transmission selector lever, manually unlocking
To do so, insert a pin (1), e.g. ball point pen, into the covered opening below the position “D” of the shift pattern. While pushing the pin down, move selector lever from position “P”. After removal of the pin from the opening, the cover will not close fully. Only after moving the selector lever to positions “D+” and “D–” does the cover return to its closed position.
In the case of power failure the transmission selector lever can be manually unlocked, e.g. to tow the vehicle.

Bulbs
Headlamp adjustment Correct headlamp adjustment is extremely important. Check and readjust headlamps at regular intervals and when a bulb has been replaced. For adjusting headlamp aim see page 261.
Replacing bulbs
Warning! Bulbs and bulb holders can be very hot. Allow the lamp to cool down before changing a bulb. Halogen lamps contain pressurized gas. A bulb can explode if you:
• touch or move it when hot, • drop the bulb, • scratch the bulb.
Wear eye and hand protection.
Notes: To prevent a possible electrical short circuit, switch off lamp prior to replacing a bulb. When replacing bulbs, install only 12 volt bulbs with the specified watt rating. When replacing halogen bulbs do not touch glass portion of bulb with bare hands. Use plain paper or a clean cloth.
Warning! Because of high voltage in Xenon lamps, it is dangerous to replace the bulb or repair the lamp and its components. We recommend that you have such work done by a qualified technician.
