Fuses Most of your vehicle’s electrical components are fused with safety fuses. With the exception of the brake lights, all individual lighting system components are electronically fused. Before replacing a blown safety fuse, determine the cause of the short circuit. Always observe amperage and color of fuse. The circuit for components is protected by a cycled circuit breaker interrupted if too much current is being drawn. The circuit closes automatically after a short time; the circuit is broken again if the malfunction reoccurs. Always use a new fuse for replacement. Never attempt to repair or bridge a blown fuse. A fuse chart, spare fuses and a fuse extractor are located in the vehicle tool kit in the luggage bowl under the trunk floor. See page 335 for notes on the vehicle tool kit.

Warning! To help prevent personal injury, stay clear of moving parts when the hood is open and the engine is running. Be sure the hood is properly closed before driving. When closing hood, use extreme caution not to catch hands or fingers. The radiator fan may continue to run for approximately 30 seconds or even restart after the engine has been turned off. Stay clear from fan blades. If you see flames or smoke coming from the engine compartment, or if the coolant temperature gauge indicates that the engine is overheated, do not open the hood. Move away from vehicle and do not open the hood until the engine has cooled. If necessary, call a fire department.

The engine is equipped with a transistorized ignition system. Because of the high voltage it is dangerous to touch any components (ignition coils, spark plug sockets, diagnostic socket) of the ignition system

• with the engine running, • while starting the engine, • if ignition is “on“ and the engine is turned

manually.

To open: To unlock the hood, pull release lever (1) under the driver’s side of the instrument panel. At the same time a handle will extend out of the radiator grill.

Pull handle (2) to its stop out of radiator grill and open hood (do not pull up on the handle).

The engine oil level can be checked by either the oil dipstick or via the multifunction display in the instrument cluster, see page 154. Wipe the oil dipstick clean prior to checking the engine oil level. Fully insert dipstick in tube, and remove after three seconds to obtain accurate reading.

See malfunction and warning messages on page 297 if an engine oil level display appears on the multifunction display when the engine is running.

Note: See page 154 for engine oil level indicator.

The oil level must be between the lower mark (min) and the upper mark (max) on the oil dipstick.

Unscrew the oil filler cap and add oil carefully if you need to top up the oil. CL 500 and CL 55 AMG: Fill quantity between upper and lower dipstick marking level is approximately 2.1 US qt (2.0 l). CL 600: Follow the message appearing on the engine oil level indicator display (page 154) as to quantity to be added. Re-install oil filler cap. 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.

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.

Active body control (ABC) fluid level Regular fluid level check is not required. If you notice fluid leaks or malfunctions, have your authorized Mercedes-Benz Center check the ABC-system.

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 397 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.

Warning! The jack is designed exclusively for jacking up the vehicle at the jack tubes 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 inserted in the jack tube. Always lower the vehicle onto sufficient capacity jackstands before working under the vehicle.

P58.10-2001-26

To prepare the jack for use: Remove the jack from the spare wheel well under the trunk floor, push the crank handle up and turn clockwise until it engages (operational position).

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 approx. 60 miles (100 km) at moderate speed.

It is imperative that the wheel mounting bolts be fastened to a tightening torque of 110 ft.lb. (150 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 345.

Spare wheel Spare wheel CL 500 and CL 600 (except Sport Package)

Important! The spare wheel rim is mounted with a full size tire of the same type as on the vehicle, 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 flat tire, you may temporarily use the spare wheel. Do not operate vehicle with more than one spare wheel mounted.

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.

Spare wheel CL 55 AMG and Sport Package

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. 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.

Important! The spare wheel rim size is 71/2 J x 17 H 2 with tire size 225/55 R17 97H. The 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 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.

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 spare wheel should only be used temporarily, and replaced with a regular road wheel as quick as possible. CL 55 AMG and Sport Package: 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.

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

following the sequence illustrated, until all bolts are tight. Observe a tightening torque of 110 ft.lb. (150 Nm).

13. Ensure proper tire pressure.

Notes: Before storing the jack, the jack arm must be lowered almost to the base of the jack. For proper storage of vehicle jack see page 335.

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.

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..

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.

The maintenance-free battery is located in the trunk under the right-hand wheel well cover panel. For battery removal or installation, or jump starting the vehicle, first lift the trunk floor, then turn lock (1) counterclockwise and remove cover.

Important! Battery replacement information:

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.

Note: After reconnecting the battery also set the clock (see COMAND operator’s manual) resynchronize the express feature of the power windows (see page 180), the sliding/pop-up roof (see page 183), and the electronic stability program (see page 272).

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.

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 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).

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 right-hand wheel well cover panel.

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”.

Important!

3. Clamp one end of the first jumper cable to the

positive (+) 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.

350

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.

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

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 (vehicles with KEYLESS-GO: in “On” position, see page 224), 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 “VEHICLE” under “Individual settings” on page 144. 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.

Note: The selector lever will remain locked in position “P” and the electronic key could not be turned in the starter switch if the battery is disconnected or discharged. See battery on page 346 or jump starting on page 349.

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.

2 Cover right side of rear 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. 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. Use wheel lift, dolly, or flat bed equipment, with electronic key in starter switch 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.

Note: To signal turns while being towed with hazard warning flasher in use, turn electronic key in starter switch 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!
