2004 Mercedes-benz CL Class Owners Manual

The most important rule for slippery or icy roads is to drive sensibly and to avoid abrupt acceleration, braking and steering maneuvers. Do not use the cruise control system under such conditions. When the vehicle is in danger of skidding, move gear selector lever to position N. Try to keep the vehicle under control by cor- rective steering action.

For information on driving with snow chains, see “Snow chains” (컄 page 281).

Warning!

On slippery road surfaces, never downshift in order to obtain braking action. This could result in drive wheel slip and reduced vehi- cle control. Your vehicle’s ABS will not pre- vent this type of control loss.

Operation Driving instructions

Warning!

Standing water

Road salts and chemicals can adversely af- fect braking efficiency. Increased pedal force may become necessary to produce the normal braking effect. Depressing the brake pedal periodically when traveling at length on salt-strewn roads can bring road-salt impaired braking efficiency back to normal. If the vehicle is parked after being driven on salt-treated roads, the braking efficien- cy should be tested as soon as possible af- ter driving is resumed.

If the vehicle becomes stuck in snow, make sure that snow is kept clear of the exhaust pipe and from around the vehicle with the engine running. Otherwise, deadly carbon monoxide (CO) gases may enter vehicle in- terior resulting in unconsciousness and death.

To assure sufficient fresh air ventilation, open a window slightly on the side of the ve- hicle not facing the wind.

Warning!

Warning!

Make sure not to endager any other road users when carrying out these braking ma- neuvers.

The outside temperature indicator is not de- signed to serve as an ice-warning device and is therefore unsuitable for that purpose. In- dicated temperatures just above the freez- ing point do not guarantee that the road surface is free of ice.

For more information on winter driving, see “Winter driving” (컄 page 280).

Do not drive through flooded areas or water of unknown depth. Before driving through water, determine its depth. Never accelerate before driving into water. The bow wave could force water into the engine and auxiliary equip- ment, thus damaging them. If you must drive through standing wa- ter, drive slowly to prevent water from entering the passenger compartment or the engine compartment. Water in these areas could cause damage to electrical components or wiring of the engine or transmission, or could result in water being ingested by the engine through the air intake causing severe internal engine damage. Any such dam- age is not covered by the Mercedes-Benz Limited Warranty.

Operation Driving instructions

Passenger compartment

Warning!

Always fasten items being carried as secure- ly as possible.

In an accident, during hard braking or sud- den maneuvers, loose items will be thrown around inside the vehicle, and cause injury to vehicle occupants unless the items are securely fastened in the vehicle.

The trunk is the preferred place to carry ob- jects.

Driving abroad

Abroad, there is an extensive Mercedes-Benz service network at your disposal. If you plan to drive into areas which are not listed in the index of your Mercedes-Benz Center directory, you should request pertinent information from an authorized Mercedes-Benz Center.

Control and operation of radio trans- mitters

Telephones and two-way radios

COMAND, radio and telephone*

Warning!

Please do not forget that your primary responsibility is to drive the vehicle safely. Only operate the COMAND (Cockpit Man- agement and Data System), radio or tele- phone1 if road, weather and traffic conditions permit.

Bear in mind that at a speed of just 30 mph (approximately 50 km/h), your vehicle is covering a distance of 44 feet (approximate- ly 14 m) every second.

1 Observe all legal requirements.

Warning!

Never operate radio transmitters equipped with a built-in or attached antenna (i.e. with- out being connected to an external antenna) from inside the vehicle while the engine is running. Doing so could lead to a malfunc- tion of the vehicle’s electronic system, pos- sibly resulting in an accident and/or personal injury.

Radio transmitters, such as a portable tele- phone or a citizens band unit should only be used inside the vehicle if they are con- nected to an antenna that is installed on the outside of the vehicle. Refer to the radio transmitter operation in- structions regarding use of an external an- tenna.

Catalytic converter

Your Mercedes-Benz is equipped with monolithic-type catalytic converters, an important element in conjunction with the oxygen sensors to achieve substantial con- trol of the pollutants in the exhaust emis- sions. Keep your vehicle in proper operating condition by following our rec- ommended maintenance instructions as outlined in your Service Booklet.

To prevent damage to the catalytic con- verters, use only premium unleaded gasoline in this vehicle. Any noticeable irregularities in engine operation should be dealt with prompt- ly. Otherwise, excessive unburned fuel may reach the catalytic converter, causing it to overheat and start a fire.

Operation Driving instructions

Warning!

Emission control

As with any vehicle, do not idle, park or op- erate this vehicle in areas where combusti- ble materials such as grass, hay or leaves can come into contact with the hot exhaust system, as these materials could be ignited and cause a vehicle fire.

Certain systems of the engine serve to keep the toxic components of the exhaust gases within permissible limits required by law. These systems, of course, will function properly only when maintained strictly ac- cording to factory specifications. Any ad- justments to the engine should therefore be carried out only by qualified Mercedes-Benz Center authorized techni- cians. Engine adjustments should not be altered in any way. Moreover, the specified service jobs must be carried out regularly accord- ing to Mercedes-Benz servicing require- ments. For details refer to the Service Booklet.

255

Operation Driving instructions

Warning!

Coolant temperature

Inhalation of exhaust gas is hazardous to your health. All exhaust gas contains carbon monoxide, and inhaling it can cause uncon- sciousness and lead to death.

Do not run the engine in confined areas (such as a garage) which are not properly ventilated. If you think that exhaust gas fumes are entering the vehicle while driving, have the cause determined and corrected immediately. If you must drive under these conditions, drive with at least one window fully open at all times.

During severe operating conditions, e.g. stop-and-go traffic, the coolant tem- perature may rise close to approx. 248°F (120°C). The engine should not be operated with the coolant temperature over 248°F (120°C). Doing so may cause serious en- gine damage which is not covered by the Mercedes-Benz Limited Warranty.

Warning!

앫 Driving when your engine is badly over-

heated can cause some fluids, which may have leaked into the engine com- partment, to catch fire. You could be se- riously burned.

앫 Steam from an overheated engine can cause serious burns and can occur just by opening the hood. Stay away from the engine if you see or hear steam com- ing from it.

Turn off the engine, get out of the vehicle and do not stand near the vehicle until the engine has cooled down.

Operation Engine compartment

Only use washer fluid which is suitable for plastic lenses. Improper washer fluid can damage the plastic lenses of the headlamps.

If the windshield washer system on your vehicle is heated*, a fluid mixture produced to resist freezing at tempera- tures of approximately 14°F (–10°C) should be sufficient.

For more information, see “Windshield and headlamp washer system” (컄 page 379).

왘 Refill the reservoir with MB Windshield

Washer Concentrate and water (or commercially available premixed wind- shield washer solvent/antifreeze, de- pending on ambient temperatures). Always use washer solvent/antifreeze where temperatures may fall below freezing point. Failure to do so could re- sult in damage to the washer sys- tem/reservoir.

Warning!

Washer solvent/antifreeze is highly flamma- ble. Do not spill washer solvent/antifreeze on hot engine parts, because it may ignite and burn. You could be seriously burned.

Operation Tires and wheels 왔 Tires and wheels See an authorized Mercedes-Benz Center for information on tested and recommend- ed rims and tires for summer and winter operation. They can also offer advice con- cerning tire service and purchase.

Warning!

Replace rims or tires with the same designa- tion, manufacturer and type as shown on the original part. See an authorized Mercedes-Benz Center for further informa- tion. If incorrectly sized rims and tires are mounted: 앫 The wheel brakes or suspension compo-

nents can be damaged.

앫 The correct operating clearance of the wheels and the tires are no longer guar- anteed.

270

Warning!

Important guidelines

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 re- sult in the bolts loosening and possibly an accident.

Retreaded tires are not tested or recom- mended by Mercedes-Benz, since previous damage cannot always be recognized on retreads. Mercedes-Benz can therefore not assure the operating safety of the vehi- cle when such tires are used. See an authorized Mercedes-Benz Center for information on tested and recommend- ed rims and tires for summer and winter operation.

앫 Only use sets of tires and rims of the

same type and make.

앫 Tires must be of the correct size for the

rim.

앫 Break in new tires for approximately

60 miles (100 km) at moderate speeds.

앫 Regularly check the tires and rims for

damage. Dented or bent rims can cause tire pressure loss and damage to the tire beads.

앫 If vehicle is heavily loaded, check tire

pressure and correct as required.

앫 Do not allow your tires to wear down too far. Adhesion properties on wet roads are sharply reduced at tread depths under 1/8 in (3 mm).

앫 When replacing individual tires, you should mount new tires on the front wheels first (on vehicles with same-sized wheels all around).

Life of tires

Direction of rotation

Checking tire inflation pressure

Operation Tires and wheels

Unidirectional tires offer added advantag- es, such as better hydroplaning perfor- mance. To benefit, however, you must make sure the tires rotate in the direction specified. An arrow on the sidewall indicates the in- tended direction of tire rotation.

The service life of a tire is dependent upon varying factors including but not limited to: 앫 Driving style 앫 Tire pressure 앫 Distance driven

Warning!

Tires and spare tire should be replaced after six years, regardless of the remaining tread.

Keep unmounted tires in a cool, dry place with as little exposure to light as possible. Protect tires from contact with oil, grease and gasoline.

Warning!

If the tire pressure repeatedly drops: 앫 Check the tires for punctures from for-

eign objects.

앫 Check to see whether air is leaking from

the valves or from around the rim.

Regularly check your tire pressure at inter- vals of no more than 14 days. Correct the tire pressure only when tires are cold. If the tires are warm, you should only cor- rect the tire pressure if it is too low for cur- rent operating conditions. A table on the fuel filler flap lists the spec- ified tire inflation pressures for warm and cold tires as well as for various operating conditions.

271

Check the spare tire periodically for condi- tion and inflation pressure. Spare tires will age and become worn over time even if never used, and thus should be inspected and replaced when necessary or after a maximum of six years.

Operation Tires and wheels

The pressures listed for light loads are minimum values offering high driving comfort. Increased inflation pressures listed for heavier loads may also be used for light loads. These higher pressures produce favorable handling characteristics. The ride of the vehicle, however, will be somewhat harder. Never exceed the max. values or inflate tires below the min. values listed on the fuel filler flap.

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 where the temperature is different from the outside temperature. Tire temperature and tire pressure also in- crease while driving, depending on the driving speed and the tire load.

272

Warning!

Follow recommended tire inflation pres- sures.

Do not overinflate tires. Overinflated tires can result in sudden deflation (blowout) be- cause they are more likely to become punc- tured or damaged by road debris, potholes, etc.

Do not underinflate tires. Underinflated tires wear unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated.

Do not overload the tires by exceeding the specified vehicle capacity weight (as indicat- ed by the label on the pillar in the driver’s door opening). Overloading the tires can overheat them, possibly causing a blowout.

Checking tire pressure electronically* (vehicles produced up to approximate- ly October 2003)

Check with an authorized Mercedes-Benz Center to determine the equipment installed in your vehicle.

The tire inflation pressure monitor only functions on wheels that are equipped with the proper electronic sensors. It monitors the tire inflation pressure, as selected by the driver, in all four tires. A warning is is- sued to alert you to a decrease in pressure in one or more of the tires. Tire pressure inquiries are made using the multifunction display (컄 page 129). The in- flation pressures are displayed only after a few minutes travel time. You can select the unit of measure used for the tire inflation pressure by changing the setting in the control system (컄 page 129).

Possible differences between the read- ings of a tire pressure gauge of an air hose, e.g. gas station equipment, and the vehicle’s control system can occur. The readings issued by the control sys- tem are more precise.

왘 Switch on ignition. 왘 Press button è or ÿ on the mul-

tifunction steering wheel repeatedly until the standard display menu ap- pears in the multifunction display (컄 page 129).

왘 Press button k or j repeatedly until you see the current inflation pres- sures for each tire appear in the dis- play.

Operation Tires and wheels

Warning!

The tire inflation pressure monitor does not indicate a warning for wrongly selected in- flation pressures. Always adjust tire inflation pressure according to the label on the fuel filler flap.

The tire inflation pressure monitor is not able to issue a warning due to a sudden dra- matic loss of pressure (e.g. tire blowout caused by a foreign object). In this case bring the vehicle to a halt by carefully apply- ing the brakes and avoiding abrupt steering maneuvers.

Operating radio transmission equip- ment (e.g. wireless headsets, two-way radios) in or near the vehicle could cause the tire inflation pressure moni- tor to malfunction.

Operation Tires and wheels

Checking tire pressure electronically* (vehicles produced as of approximately October 2003)

Check with an authorized Mercedes-Benz Center to determine the equipment installed in your vehicle.

The tire inflation pressure monitor only functions on wheels that are equipped with the proper electronic sensors. It monitors the tire inflation pressure, as selected by the driver, in all four tires. A warning is is- sued to alert you to a decrease in pressure in one or more of the tires. You can call up the tire pressure using the control system (컄 page 129).

275

Operation Tires and wheels

After you have reactivated the tire pressure monitor, the current tire pres- sures will only be shown after a few minutes’ driving time. During this time, you will see the follow- ing message in the display: TIRE PRES. DISPLAY APPEARS AFTER DRIVING A FEW MINUTES

Possible differences between the read- ings of a tire pressure gauge of an air hose, e.g. gas station equipment, and the vehicle’s control system can occur. The readings issued by the control sys- tem are more precise.

왘 Switch on ignition. 왘 Press button è or ÿ on the mul-

tifunction steering wheel repeatedly until the standard display menu ap- pears in the multifunction display (컄 page 129).

왘 Press button k or j repeatedly until you see the current inflation pres- sures for each tire appear in the dis- play.

Warning!

When the tire pressure monitoring system warning lamp is lit, one or more of your tires is significantly under-inflated. You should stop and check your tires as soon as possi- ble, and inflate them to the proper pressure as indicated on the vehicle’s tire information placard. Driving on a significantly under-in- flated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability. Each tire, including the spare, should be checked monthly when cold and set to the recommended inflation pressure as specified in the vehicle placard and owner’s manual.

The recommended tire inflation pres- sure for your vehicle can be found on the inside of the fuel filler flap, not in the owner’s manual.

Warning!

Warning!

The tire inflation pressure monitor does not indicate a warning for wrongly selected in- flation pressures. Always adjust tire inflation pressure according to the label on the fuel filler flap.

The tire inflation pressure monitor is not able to issue a warning due to a sudden dra- matic loss of pressure (e.g. tire blowout caused by a foreign object). In this case bring the vehicle to a halt by carefully apply- ing the brakes and avoiding abrupt steering maneuvers.

Operating radio transmission equip- ment (e.g. wireless headsets, two-way radios) in or near the vehicle could cause the tire inflation pressure moni- tor to malfunction.

Follow recommended tire inflation pres- sures.

Do not overinflate tires. Overinflating tires can result in sudden deflation (blowout) be- cause they are more likely to become punc- tured or damaged by road debris, potholes, etc.

Do not underinflate tires. Underinflated tires wear unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated.

Do not overload the tires by exceeding the specified vehicle capacity weight (as indicat- ed by the label on the pillar in the driver’s door opening). Overloading the tires can overheat them, possibly causing a blowout.

Rotating wheels

Warning!

Rotate front and rear wheels only if they are of the same size.

On vehicles with the same wheel size all around, wheels can be rotated every 3000 to 6000 miles (5000 to 10000 km), or sooner if necessary, according to the de- gree of tire wear. The same direction of tire rotation must be retained. Rotate the wheels before the characteris- tic tire wear pattern becomes visible (shoulder wear on front wheels and tread center wear on rear wheels).

Thoroughly clean the inner side of the wheels after each rotation. Check and en- sure proper tire inflation pressure. If nec- essary, activate the tire inflation pressure monitor.

Your vehicle is equipped with a tire in- flation pressure monitor, there are electronic components built into the wheel. Do not use mounting tools in the area of the valve as they could damage the electronic components. To prevent damage or incorrect instal- lation, have the tires changed at an au- thorized Mercedes-Benz Center.

Operation Tires and wheels

Warning!

Have the tightening torque checked after changing a wheel. Wheels could become loose if not tightened with a torque of 110 lb-ft. (150 Nm).

Use only genuine Mercedes-Benz wheel bolts specified for your vehicle's rims.

For information on wheel change, see the “Practical hints” section (컄 page 329) and (컄 page 343).

Operation Winter driving 왔 Winter driving Before the onset of winter, have your vehi- cle winterized at an authorized Mercedes-Benz Center. This service in- cludes: 앫 Check of anticorrosion and antifreeze

concentration.

앫 Addition of cleaning concentrate to the water of the windshield and headlamp cleaning system. Add MB Concentrate “S” to a premixed windshield washer solvent/antifreeze which is formulated for temperatures below freezing point (컄 page 377)

앫 Battery test. Battery capacity drops

with decreasing ambient temperature. A well-charged battery helps to ensure that the engine can be started even at low ambient temperatures.

앫 Tire change. Mercedes-Benz recom-

mends M+S rated radial-ply tires with a minimum tread depth of approximately 1⁄ 6 in (4 mm) on all four wheels for the winter season.

280

Winter tires

Always use winter tires at temperatures below 45°F (7°C) and whenever wintry road conditions prevail. Use of winter tires is the only way to achieve the maximum ef- fectiveness of the ABS and the ESP in win- ter operation. For safe handling, make sure that all mounted winter tires are of the same make and have the same tread design.

Warning!

Winter tires with a tread depth of less than 1⁄ 6 in (4 mm) must be replaced. They are no longer suitable for winter operation.

Always observe the speed rating of the winter tires installed on your vehicle. If the maximum speed for which your tires are rated is below the speed rating of your ve- hicle, you must place a notice to this effect where it will be seen by the driver. Such no- tices are available at your tire dealer or any authorized Mercedes-Benz Center.

Warning!

If you use your spare tire when winter tires are fitted on the other wheels, be aware that the difference in tire characteristics may very well impair turning stability and that overall driving stability may be reduced. Adapt your driving style accordingly.

Have the spare tire replaced with a winter tire at the nearest authorized Mercedes-Benz Center.

Operation Winter driving

Block heater (Canada only)

The engine is equipped with a block heat- er. The electrical cable may be installed at an authorized Mercedes-Benz Center.

When driving with snow chains, you may wish to deactivate the ESP (컄 page 80) before setting the vehicle in motion. This will improve the vehicle‘s traction.

Do not use snow chains with tire sizes 245/45 R18 on 8½J x 18 rim and 265/40 R18 in general (컄 page 365). Do not use snow chains on tires mounted on AMG rims.

Snow chains

When using snow chains, the vehicle should only be driven at vehicle height 1 (컄 page 211).

Snow chains should only be driven on snow-covered roads at speeds not to exceed 30 mph (50 km/h). Remove chains as soon as possible when driving on roads without snow.

Please observe the following guidelines when using snow chains: 앫 Use of snow chains is not permissible

with all wheel/tire combinations.

앫 Snow chains should only be used on the rear wheels. Follow the manufac- turer's mounting instructions.

앫 Only use snow chains that are ap-

proved by Mercedes-Benz. Your autho- rized Mercedes-Benz Center will be glad to advise you on this subject.

앫 Use of snow chains may be prohibited depending on location. Always check local and state laws before installing snow chains.

Operation Vehicle care 왔 Vehicle care Cleaning and care of vehicle

Warning!

Many cleaning products can be hazardous. Some are poisonous, others are flammable. Always follow the instructions on the partic- ular container. Always open your vehicle’s doors or windows when cleaning the inside.

Never use fluids or solvents that are not de- signed for cleaning your vehicle.

While in operation, even while parked, your vehicle is subjected to varying external in- fluences which, if gone unchecked, can at- tack the paintwork as well as the underbody and cause lasting damage.

284

Such damage is caused not only by ex- treme and varying climatic conditions, but also by: 앫 Air pollution 앫 Road salt 앫 Tar 앫 Gravel and stone chipping To avoid paint damage, you should imme- diately remove: 앫 Grease and oil 앫 Fuel 앫 Coolant 앫 Brake fluid 앫 Bird droppings 앫 Insects 앫 Tree resins, etc. Frequent washing reduces and/or elimi- nates the aggressiveness and potency of the above adverse influences.

More frequent washings are necessary to deal with unfavorable conditions: 앫 near the ocean 앫 in industrial areas (smoke, exhaust

emissions)

앫 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 corrosion. In doing so, do not neglect the underbody of the vehicle. A prerequisite for a thor- ough check is a washing of the underbody followed by a thorough inspection. Dam- aged areas need to be re-undercoated. Your vehicle has been treated at the facto- ry 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 ap- plied later.

Operation Vehicle care

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 an 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 an au- thorized 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 prod- ucts. Additional information can be found in the booklet “Vehicle Care Guide“.

Power washer When using a power washer for cleaning the vehicle, always observe the manufac- turer’s operating instructions.

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

Vehicles with KEYLESS-GO*: If a door handle is hit by a strong jet of water, and a SmartKey with KEYLESS-GO* is in close proximity, i.e. within approx. 3 ft. (approx. 1 m), the vehicle could be inadvertently locked or unlocked.

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 connec- tors, seals, or other rubber parts.

Paintwork, painted body components Mercedes-Benz approved Paint Care should be applied when water drops on the paint surface do not “bead up”, normally every three to five months, depending on climate and washing detergent used. Mercedes-Benz approved Paint Cleaner should be applied if the paint surface shows signs of embedded dirt (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, vehi- cle doors, etc.).

285

Operation Vehicle care

Engine cleaning Prior to cleaning the engine compartment make sure to protect electrical compo- nents and connectors from the intrusion of water and cleaning agents. Corrosion protection, such as MB Anticor- rosion Wax, should be applied to the en- gine compartment after every engine cleaning. Before applying, all control link- age bushings and joints should be lubricat- ed. 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. Only use a mild car wash detergent, such as Mercedes-Benz ap- proved Car Shampoo. Thoroughly spray the vehicle with a dif- fused jet of water. Direct only a very weak spray towards the ventilation intake. Use plenty of water and rinse the sponge and chamois frequently.

286

Rinse with clear water and thoroughly dry with a chamois. Do not allow cleaning agents to dry on the finish. Due to the width of the vehicle, fold in ex- terior rear view mirrors prior to running the vehicle through an automatic car wash to prevent damage to the mirrors. In the winter, thoroughly remove all traces of road salt as soon as possible. When washing the underbody, do not for- get to clean the inner sides of the wheels.

Vehicles with KEYLESS-GO*: If a door handle is hit by a strong jet of water, and a SmartKey with KEYLESS-GO* is in close proximity, i.e. within approx. 3 ft. (approx. 1 m), the vehicle could be inadvertently locked or unlocked.
