13. Using the wrench, tighten the five bolts evenly,

following the sequence illustrated, until all bolts are tight. Observe a tightening torque of 80 ft.lb. (110 Nm).

14. Vehicles with steel rims

Installation of wheel cover: Position small wheel cover opening over tire valve and press wheel cover against wheel rim. Now press (do not hit) opposite side of wheel cover against wheel rim until seated. Make certain that the springs of the wheel cover are firmly seated in the outer rim of the steel wheel.

Notes: Before storing the jack, it should be fully collapsed, with handle folded in. For proper storage of vehicle jack see page 304.

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.

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.

Important! Tire pressure changes by approximately 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 = approximately +68°F (+20°C) and ambient temperature = approximately +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.

Battery

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 engine compartment on the right hand side. 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 starter switch position 0. The battery, its filler caps, the vent tube and the opposite plug must always be securely installed when the vehicle is in operation.

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.

Removal of filter box: Release three clamps (1) and remove filter box. Installation of filter box: Install filter box properly and secure with three clamps (1).

Note: After reconnecting the battery also set the clock (vehicles with COMAND: see COMAND operator’s manual) resynchronize the front seat head restraints, the express feature of the power windows, the sliding/ pop-up roof, and the electronic stability program (see individual settings on page 111, head restraints on page 47, power windows on page 184, synchronizing the sliding / pop-up roof on page 188 and electronic stability program on page 260).

Battery recycling Batteries contain materials 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.

318

Jump starting

Warning! Failure to follow these directions will cause damage to the electronic components, and can lead to a battery explosion and severe injury or death. Never lean over batteries while connecting or jump starting, 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 very explosive. Keep flames or sparks away from battery, avoid improper connection of jumper cables, smoking etc. Read all instructions before proceeding.

Important! A discharged battery can freeze at approximately +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

approximately 2 AWG

• Maximum length of 11.5 ft. (3.5 m).

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 engine compartment on the right hand side.

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.

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” (manual transmission to Neutral).

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 (–) under hood terminal of the disabled vehicle.

Note: 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

Warning! Prior to towing the vehicle with all wheels on the ground, make certain that the electronic key is in starter switch position 2. If the electronic key is left in the starter switch position 0 for an extended period of time, it can no longer be turned in the switch. In this case, the steering is locked. To unlock, remove electronic key from starter switch and reinsert.

Important! When towing the vehicle, please, note the following: With the automatic central locking activated and the electronic key in starter switch position 2, the vehicle doors lock if the left front wheel as well as the right rear wheel are turning at vehicle speeds of approximately 9 mph (15 km/h) or more. To prevent the vehicle door locks from locking, deactivate the automatic central locking. See “VEHICLE” under “Individual settings” on page 119. Towing of the vehicle should only be done using the properly installed towing eye bolt. Never attach tow cable, tow rope or tow rod to vehicle chassis, frame or suspension parts.

Notes: The selector lever will remain locked in position “P” and the electronic key cannot be turned in the starter switch if the battery is disconnected or discharged. See battery on page 316 or jump starting on page 318. Transmission selector lever, manually unlocking, see page 325.

1 Cover on right side of front bumper

To remove cover: Press mark on cover in direction of arrow and lift cover off to reveal threaded hole for towing eye bolt. The towing eye bolt is supplied with the tool kit (located in trunk in spare wheel). Screw towing eye bolt in to its stop and tighten with lug wrench. To reinstall cover: Fit cover and snap into place.

We recommend that the vehicle be transported using flat bed equipment. This method is preferable to other types of towing.

Important! To prevent damage during transport, do not tie down vehicle by its chassis or suspension parts. Towing restrictions for vehicles with automatic transmission: 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 starter switch 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.

Replacing bulbs

Headlamp adjustment Correct headlamp adjustment is extremely important. Check and readjust headlamps at regular intervals and when a bulb has been replaced.

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.

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. If the newly installed bulb does not light up, switch the lamp off and on again. If the bulb still does not light up, have the system checked at an authorized Mercedes-Benz Center.

Cleaning and care of the vehicle

Warning! Many cleaning products can be hazardous. Some are poisonous, others are flammable. Always follow the instructions on the particular container. Always open your vehicle’s doors or windows when cleaning the inside. Never use fluids or solvents that are not designed for cleaning your vehicle.

In operation, your vehicle is subjected to varying external influences which, if gone unchecked, can attack the paintwork as well as the underbody and cause lasting damage. Such damage is caused not only by extreme and varying climatic conditions, but also by air polution, road salt, tar, gravel and stone chipping. Grease and oil, fuel, coolant, brake fluid, bird droppings, insects, tree resins etc. should be removed immediately to avoid paint damage. Frequent washing reduces and/or eli minates the aggressiveness and potency of the above adverse influences.

More frequent washings are necessary to deal with unfavorable conditions; for example, near the ocean, in industrial areas (smoke, exhaust emissions), or during winter operation. You should check your vehicle from time to time for stone chipping or other damage. Any damage should be repaired as soon as possible to prevent the start of corrosion. In doing so, do not neglect the underside of the vehicle. A prerequisite for a thorough check is a washing of the underbody followed by a thorough inspection. Damaged areas need to be reundercoated. Your vehicle has been treated at the factory with a wax- base rustproofing in the body cavities which will last for the lifetime of the vehicle. Post-production treatment is neither necessary nor recommended by Mercedes-Benz because of the possibility of incompatibility between materials used in the production process and others applied later. We have selected car-care products and compiled recommendations which are specially matched to our vehicles and which always reflect the latest technology. You can obtain Mercedes-Benz approved car-care products at your authorized Mercedes-Benz Center.

Scratches, corrosive deposits, corrosion or damage due to negligent or incorrect care cannot always be removed or repaired with the car-care products recommended here. In such cases it is best to seek aid at your authorized Mercedes-Benz Center. The following topics deal with the cleaning and care of your vehicle and give important “how-to” information as well as references to Mercedes-Benz approved car-care products. Additional information can be found in the booklet titled “Vehicle Care Guide”.

Power washer When using a power washer for cleaning the vehicle always observe manufacturer’s operating instructions.

Caution! Never use a round nozzle to power wash tires. The intense jet of water can result in damage to the tire. Always replace a damaged tire. Always keep the jet of water moving across the surface. Do not aim directly at electrical parts, electrical connectors, seals, or other rubber parts.

Tar stains Quickly remove tar stains before they dry and become more difficult to remove. A tar remover is recommended.

Paintwork, painted body components Mercedes-Benz approved Paint Care should be applied when water drops on the paint surface do not “bead up”, normally in 3 to 5 months, depending on climate and washing detergent used. Mercedes-Benz approved Paint Cleaner should be applied if paint surface shows signs of dirt embedding (i.e. loss of gloss). Do not apply any of these products or wax if your vehicle is parked in the sun or if the hood is still hot. Use the appropriate MB-Touch-Up Stick for quick and provisional repairs of minor paint damage (i.e. chips from stones, vehicle doors etc.).

Engine cleaning Prior to cleaning the engine compartment make sure to protect electrical components and connectors from the intrusion of water and cleaning agents. Corrosion protection, such as MB Anticorrosion Wax should be applied to the engine compartment after every engine cleaning. Before applying, all control linkage bushings and joints should be lubricated. The poly-V-belt and all pulleys should be protected from any wax.

Vehicle washing Do not use hot water or wash your vehicle in direct sunlight. Use only a mild car wash detergent, such as Mercedes-Benz approved Car Shampoo. Thoroughly spray the vehicle with a diffused jet of water. Direct only a very weak spray towards the ventilation intake. Use plenty of water and rinse the sponge and chamois frequently. Rinse with clear water and thoroughly wipe dry with a chamois. Do not allow cleaning agents to dry on the finish. Due to the width of the vehicle, prior to running the vehicle through an automatic car wash, fold back the outside mirrors to prevent them from getting damaged. In the winter, thoroughly remove all traces of road salt as soon as possible. When washing the underbody, do not forget to clean the inner sides of the wheels.

Ornamental moldings For regular cleaning and care of very dirty chrome- plated parts, use a chrome cleaner.

Window cleaning Use a window cleaning solution on all glass surfaces. An automotive glass cleaner is recommended.

Headlamps, taillamps, turn signal lenses Use a mild car wash detergent, such as Mercedes-Benz approved Car Shampoo, with plenty of water. To prevent scratches, never apply strong force and use only a soft, non-scratchy cloth when cleaning the lenses. Do not attempt to wipe dirty lenses with a dry cloth or sponge.

Note: For safety reasons, switch off wipers and remove electronic key from starter switch before cleaning the windshield, otherwise the wiper motor can suddenly turn on and cause injury.

Wiper blades Clean the wiper blade rubbers with a clean cloth and detergent solution.

Note: For safety reasons, remove electronic key from starter switch before cleaning the wiper blades, otherwise the wiper motor can suddenly turn on and cause injury.

Light alloy wheels Mercedes-Benz approved Wheel Care should be used for regular cleaning of the light alloy wheels. If possible, clean wheels once a week with Mercedes- Benz approved Wheel Care, using a soft bristle brush and a strong spray of water. Follow instructions on container.

Note: Use only acid-free cleaning materials. The acid could lead to corrosion.

Instrument cluster Use a gentle dishwashing detergent or mild detergent for delicate fabrics as a washing solution. Wipe with a cloth moistened in lukewarm solution. Do not use scouring agents.

Steering wheel and gear selector lever Wipe with a damp cloth and dry thoroughly or clean with Mercedes-Benz approved Leather Care.

Cup holder Use a gentle dishwashing detergent or mild detergent for delicate fabrics as a washing solution. Wipe with a cloth moistened in lukewarm solution. Do not use scouring agents.

Seat belts The webbing must not be treated with chemical cleaning agents. Use only clear, lukewarm water and soap. Do not dry the webbing at temperatures above 176°F (80°C) or in direct sunlight.

Warning! Do not bleach or dye seat belts as this may severely weaken them. In a crash they may not be able to provide adequate protection.

Headliner and shelf below rear window Clean with soft bristle brush, or use a dry-shampoo cleaner in case of excessive dirt.

Leather upholstery Using aftermarket seat covers or wearing clothing that have the tendency to give off coloring (e.g. when wet etc.) may cause the upholstery to become permanently discolored. By lining the seats with a proper intermediate cover, contact-discoloration will be prevented. Leather Upholstery Wipe leather upholstery with a damp cloth and dry thoroughly or clean with Mercedes-Benz approved Leather Care. Exercise particular care when cleaning perforated leather as its underside should not become wet. MB Tex Upholstery Pour Mercedes-Benz approved Interior Care onto soft lint-free cloth and apply with light pressure.

Engine oils Engine oils are specifically tested for their suitability in our engines. Therefore, use only engine oils recommended by Mercedes-Benz. Information on recommended brands is available at your authorized Mercedes-Benz Center. Please follow Service Booklet recommendations for scheduled oil changes. Failure to do so could result in engine damage not covered by the Mercedes-Benz Limited Warranty.

Engine oil additives Do not blend oil additives with engine oil. They may be harmful to the engine operation. Damage or malfunctions resulting from blending oil additives are not covered by the Mercedes-Benz Limited Warranty.

Air conditioner refrigerant R-134a (HFC) refrigerant and special PAG lubricating oil is used in the air conditioner system. Never use R-12 (CFC) or mineral-based lubricating oil, otherwise damage to the system will occur.

Brake fluid During vehicle operation, the boiling point of the brake fluid is continuously reduced through the absorption of moisture from the atmosphere. Under extremely hard operating conditions, this moisture content can lead to the formation of bubbles in the system thus reducing the system’s efficiency. The brake fluid must therefore be replaced every two years, preferably in the spring. It is recommended to use only brake fluid approved by Mercedes-Benz. Your authorized Mercedes-Benz Center will provide you with additional information.

Premium unleaded gasoline

Caution! To maintain the engine’s durability and performance, premium unleaded gasoline must be used. If premium unleaded is not available and low octane fuel is used, follow these precautions: • have the fuel tank filled only partially with unleaded regular and fill up with premium unleaded as soon as possible,

• avoid full throttle driving and abrupt acceleration, • do not exceed an engine speed of 3000 rpm, if the

vehicle is loaded with a light load such as two persons and no luggage,

• do not exceed 2/3 of maximum accelerator pedal

position, if the vehicle is fully loaded or operating in mountainous terrain.

Fuel requirements Use only Premium unleaded meeting ASTM standard D 439: The octane number (posted at the pump) must be 91 min. It is an average of both the Research (R) octane number and the Motor (M) octane number: (R+M)/2). This is also known as ANTI-KNOCK INDEX. Unleaded gasoline containing oxygenates such as Ethanol, IPA, IBA and TBA can be used provided the ratio of any one of these oxygenates to gasoline does not exceed 10%, MTBE not to exceed 15%. The ratio of Methanol to gasoline must not exceed 3% plus additional cosolvents. Using mixtures of Ethanol and Methanol is not allowed. Gasohol, which contains 10% Ethanol and 90% unleaded gasoline, can be used. These blends must also meet all other fuel requirements such as resistance to spark knock, boiling range, vapor pressure etc.

Gasoline additives A major concern among engine manufacturers is carbon build up caused by gasoline. Mercedes-Benz recommends the use of only quality gasoline containing additives that prevent the build up of carbon deposits. After an extended period of using fuels without such additives, carbon deposits can build up especially on the intake valves and in the combustion area, leading to engine performance problems such as: • warm-up hesitation, • unstable idle, • knocking/pinging, • misfire, • power loss. Do not blend other specific fuel additives with fuel. They only result in unnecessary cost, and may be harmful to the engine operation. Damage or malfunctions resulting from poor fuel quality or from blending specific fuel additives are not covered by the Mercedes-Benz Limited Warranty.

Coolants The engine coolant is a mixture of water and anticorrosion/antifreeze, which provides: • corrosion protection, • freeze protection, • boiling protection (by increasing the boiling point). The cooling system was filled at the factory with a coolant providing freeze protection to approximately - 22°F (- 30°C) and corrosion protection. If the antifreeze mixture is effective to - 22°F (- 30°C), the boiling point of the coolant in the pressurized cooling system is reached at approximately 266°F (130°C). The coolant solution must be used year round to provide the necessary corrosion protection and increase in the boil-over protection. You should have it replaced every 3 years. To provide the important corrosion protection, the solution must be at least 45% anticorrosion/antifreeze (equals a freeze protection to approximately - 22°F (- 30°C). If you use a solution that is more than 55% anticorrosion/antifreeze (freeze protection to approximately - 49°F (- 45°C), the engine temperature
