Always use winter tires at temperatures below 45‡ (7†) and whenever wintry road conditions prevail. Not all M+S rated tires provide special winter performance. Make sure the tires you use show the mountain/ snowflakeimarking on the tire sidewall. These tires meet specific snow traction performance requirements of the Rubber Manufacturers Association (RMA) and the Rubber Association of Canada (RAC) and have been designed specifically for use in snow conditions. Use of winter tires is the only way to achieve the maximum effectiveness of your vehicle’s driving safety systems such as the ABS and the ESC in winter operation. For safe handling, make sure all mounted winter tires are of the same make and have the same tread design. For information on winter tires for your vehicle model, see the “Technical data” section (Y page 486). Always observe the speed rating of the winter tires installed on your vehicle.

Snow chains ! When driving with snow chains, always select the raised level of the vehicle level control. Other settings may result in damage to your vehicle.

! Some tire sizes do not leave adequate clearance for snow chains. To help avoid serious damage to your vehicle or tires, make sure the use of snow chains is permissible as specified in the “Technical data” section of this Operator’s Manual.

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.

Observe the following guidelines when using snow chains: RUse of snow chains is not permissible with all wheel/tire combinations (Y page 486).

RUse snow chains in pairs and on rear

wheels only. Follow the manufacturer’s mounting instructions.

! If snow chains are mounted to the front wheels, they may scrape against the body or axle components. The tires or the vehicle could be damaged as a result.

ROnly use snow chains that are approved by Mercedes-Benz. Any authorized Mercedes- Benz Center will be glad to advise you on this subject.

RUse of snow chains may be prohibited

depending on location. Always check local and state laws before installing snow chains.

RDo not use snow chains on the spare wheel. i When driving with snow chains, you may

wish to switch off the ESC (Y page 212) before setting the vehicle in motion. This will improve the vehicle’s traction.

Winter driving instructions G Warning! If the vehicle becomes stuck in snow, make sure 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 interior resulting in unconsciousness and death. To assure sufficient fresh air ventilation, open a window slightly on the side of the vehicle not facing the wind. G Warning! The outside temperature indicator is not designed to serve as an ice-warning device and is therefore unsuitable for that purpose.

Version: 2.11.8.1

Indicated temperatures just above the freezing point do not guarantee that the road surface is free of ice. The road may still be icy, especially in wooded areas or on bridges. G Warning! On slippery road surfaces, never downshift in order to obtain braking action. This could result in drive wheel slip and reduced vehicle control. Your vehicle’s ABS will not prevent this type of loss of control. 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 or DISTRONIC PLUS system under such conditions. When the vehicle is in danger of skidding, shift the automatic transmission to neutral position N. Try to keep the vehicle under control by corrective steering action. i For information on driving with snow

chains, see “Snow chains” (Y page 396).

Road salts and chemicals can adversely affect braking efficiency. Increased pedal force may become necessary to produce the normal brake 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 efficiency should be tested as soon as possible after driving is resumed. G Warning! Make sure not to endanger any other road users when carrying out these braking maneuvers.

Driving instructions

Driving instructions Drive sensibly – save fuel To save fuel you should: RKeep tires at the recommended inflation

pressures.

RRemove unnecessary loads. RRemove roof rack when not in use. RAllow engine to warm up under low load

use.

RAvoid frequent acceleration and

deceleration.

RHave all maintenance work performed at the intervals specified in the Maintenance Booklet and as required by the Maintenance system. Contact an authorized Mercedes-Benz Center.

Fuel consumption is also increased by driving in cold weather, in stop-and-go traffic, on short trips and in mountainous areas.

Drinking and driving G Warning! Drinking and driving and/or taking drugs and driving are very dangerous combinations. Even a small amount of alcohol or drugs can affect your reflexes, perceptions and judgment. The possibility of a serious or even fatal accident are greatly increased when you drink or take drugs and drive. Do not drink or take drugs and drive or allow anyone to drive who has been drinking or taking drugs.

Pedals G Warning! Make sure absolutely no objects are obstructing the pedals’ range of movement. Keep the driver’s footwell clear of all

398 Driving instructions

obstacles. If there are any floormats or carpets in the footwell, make sure that the pedals still have sufficient clearance. During sudden driving or braking maneuvers, the objects could get caught between the pedals. You could then no longer brake or accelerate. This could lead to accidents and injury.

Power assistance G Warning! There is no power assistance for the steering and the brake when the engine is not running. Steering and braking requires significantly more effort and you could lose control of the vehicle and cause an accident as a result. Do not turn off the engine while the vehicle is in motion.

Brakes Downhill grades ! When driving down long and steep

grades, relieve the load on the brakes by shifting into a lower gear to use the engine’s braking power. This helps prevent overheating of the brakes and reduces wear. When using the engine’s braking power, a drive wheel may not spin for an extended period of time, e.g. on slippery road surfaces. This may cause serious damage to the drivetrain which is not covered by the Mercedes-Benz Limited Warranty.

Continuous or hard braking G Warning! Resting your foot on the brake pedal will cause excessive and premature wear of the brake pads.

It can also result in the brakes overheating, thereby significantly reducing their effectiveness. It may not be possible to stop the vehicle in sufficient time to avoid an accident. After hard braking, it is advisable to drive on for some time, rather than immediately park, so that the air stream will cool down the brakes faster.

Wet roads G Warning! After driving in heavy rain for some time without applying the brakes or through water deep enough to wet brake components, the first braking action may be somewhat reduced and increased pedal pressure may be necessary to obtain expected brake effect. Maintain a safe distance from vehicles in front. To help prevent brake disk corrosion after driving on wet or salt-covered roads, it is advisable to brake the vehicle with considerable force prior to parking. The heat generated serves to dry the brakes.

Salt-covered roads G Warning! A layer of salt on the brake discs and the brake linings may cause a delay in the braking effect, resulting in a significantly increased braking distance, which could lead to an accident. To avoid this danger, you should: Roccasionally brake carefully when you are driving on salt-covered roads, so that any layer of salt that may have built up on the brake discs and the brake linings is

Rmaintain a greater distance to the vehicle

ahead and drive with particular care

Rcarefully apply the brakes at the end of a trip and immediately after commencing a new trip, so that salt residues are removed from the brake disc

Brake service ! The brake fluid level in the reservoir may be too low if the red brake warning lamp in the instrument cluster comes on while the engine is running and an acoustic warning sounds. Observe additional messages in the multifunction display that may appear. Brake pad wear or a leak in the system may be the reason for low brake fluid in the reservoir. Have the brake system inspected immediately. Contact an authorized Mercedes-Benz Center.

All checks and service work on the brake system should be carried out by qualified technicians only. Contact an authorized Mercedes-Benz Center. Only install brake pads and use brake fluid recommended by Mercedes-Benz. G Warning! If other than recommended brake pads are installed, or other than recommended brake fluid is used, the braking properties of the vehicle can be degraded to an extent that safe braking is substantially impaired. This could result in an accident.

! Vehicles with 4MATIC:

Only conduct operational or performance tests on a two-axle dynamometer. If such tests are necessary, contact an authorized Mercedes-Benz Center. You could otherwise seriously damage the brake system or the transfer case which is not

covered by the Mercedes-Benz Limited Warranty.

! Vehicles with 4MATIC:

Because the ESC operates automatically, the engine and ignition must be shut off (SmartKey in starter switch position 0 or 1 or KEYLESS-GO start/stop button in position 0 or 1) when the electronic parking brake is being tested on a brake test dynamometer. Active braking action through the ESC may otherwise seriously damage the brake system which is not covered by the Mercedes-Benz Limited Warranty.

! Vehicles without 4MATIC:

Because the ESC operates automatically, the engine and ignition must be shut off (SmartKey in starter switch position 0 or 1 or KEYLESS-GO start/stop button in position 0 or 1) when the electronic parking brake is being tested on a brake test dynamometer or when the vehicle is being towed with one axle raised. Active braking action through the ESC may otherwise seriously damage the brake system which is not covered by the Mercedes-Benz Limited Warranty.

If your brake system is only subjected to moderate loads, you should occasionally test the effectiveness of the brakes by applying above-normal braking pressure at higher speeds. This will also enhance the grip of the brake pads. G Warning! Make sure not to endanger any other road users when carrying out these braking maneuvers. Refer to the description of the Brake Assist System (BAS) (Y page 57) or BAS PLUS (Y page 57).

High-performance brake system The high-performance brake system is only available on CL 63 AMG and CL 65 AMG. G Warning! New vehicle brake pads and discs, and replacement brake pads and discs may take several hundred miles of driving until they provide optimum braking efficiency. Until that time, you may need to use increased brake pedal pressure while braking. Please be aware of this and adjust your driving and braking accordingly during this break-in period. Excessive high-demand braking will cause correspondingly high brake wear. Please be attentive to the brake warning lamp in the instrument cluster and brake condition messages in the multifunction display. Especially for high performance driving, it is important to maintain and have the brake system checked regularly. The high-performance brake system is designed to operate under the extremely high operating demands required to accommodate the performance capabilities of the vehicle. The brakes may produce a squeaking-type noise depending on the Rvehicle speed Rbrake force applied Rambient conditions, e.g. temperature and

humidity

As with any brake system, the wear of individual brake system components such as brake pads or disks strongly depends on your driving style and the conditions under which you operate the vehicle. Thus, a driving style calling for high-demand braking will cause your vehicle’s brakes to wear more quickly.

Driving off Warm up the engine smoothly. Do not place full load on the engine until the operating temperature has been reached. ! When driving off on a slippery surface, do

not allow a drive wheel to spin for an extended period with the ESC switched off. Doing so may cause serious damage to the drivetrain which is not covered by the Mercedes-Benz Limited Warranty.

! Simultaneously depressing the

accelerator pedal and applying the brakes reduces engine performance and causes premature brake and drivetrain wear which is not covered by the Mercedes-Benz Limited Warranty.

Hydroplaning Depending on the depth of the water layer on the road, hydroplaning may occur, even at low speeds and with new tires. In heavy rain or when conditions indicate possible hydroplaning: X Reduce vehicle speed. X Avoid track grooves in the road. X Apply brakes cautiously.

Standing water ! Do not drive through flooded areas.

Before driving through water, determine its depth. If you must drive through standing water, 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 damage is not covered by the Mercedes- Benz Limited Warranty.

engine damage and/or other vehicle damage not covered by the Mercedes-Benz Limited Warranty.

Vehicle care Cleaning and care of the vehicle Notes Regular and proper care will help to maintain the value of your vehicle. G 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. Always lock away cleaning products and keep them out of reach of children.

! When cleaning the vehicle, do not use

scouring agents. Never apply strong force and only use a soft, wet cloth or sponge. Otherwise you may scratch or damage the surface to be cleaned.

While in operation, even while parked, your vehicle is subjected to varying external influences which, if gone unchecked, can attack the paintwork as well as the vehicle underbody and cause lasting damage. Such damage is caused not only by extreme and varying climatic conditions, but also by: RAir pollution RRoad salt RTar RGravel and stone chipping

Version: 2.11.8.1

To avoid paint damage, you should immediately remove: RGrease and oil RFuel RCoolant RBrake fluid RBird droppings RInsects RTree resins etc. Frequent washing reduces and/or eliminates the aggressiveness and potency of the above adverse influences. More frequent washings are necessary to deal with unfavorable conditions: Rnear the ocean Rin industrial areas (smoke, exhaust

emissions)

Rduring 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 thorough check is a washing of the underbody followed by a thorough inspection. Damaged areas need to be re-undercoated. 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 vehicle-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 vehicle-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 vehicle-care products recommended here. In such cases it is best to seek aid at an 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 vehicle-care products.

Power washer ! Follow the instructions provided by the

power washer manufacturer on maintaining a distance between the vehicle and the nozzle of the power washer. 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.

i Vehicles with KEYLESS-GO:

If a door handle is hit by a strong jet of water, and a SmartKey is within approximately 3 ft (1 m) of the vehicle, it could be inadvertently locked or unlocked.

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

Paintwork, painted body components ! Affixing stickers, magnets, adhesive tape

or similar materials to painted body components may damage the paintwork. Mercedes-Benz approved Paint Care should be applied when water drops on the paint surface do not “bead up”. This should

normally be done every 3 to 5 months, depending on the 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. X 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 contact with 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 In the winter, thoroughly remove all traces of road salt as soon as possible. When washing the vehicle underbody, do not forget to clean the inner sides of the wheels. i Vehicles with KEYLESS-GO:

If a door handle is hit by a strong jet of water, and a SmartKey is within approximately 3 ft (1 m) of the vehicle, it could be inadvertently locked or unlocked.

Hand-wash X Do not use hot water or wash your vehicle

in direct sunlight.

X Only use a soft, wet cloth or sponge to

clean the vehicle.

X Only use a mild vehicle wash detergent,

such as Mercedes-Benz approved Car Shampoo.

X Thoroughly spray the vehicle with a

diffused jet of water.

X Do not spray directly towards the

ventilation intake.

X Use plenty of water and rinse the sponge

and chamois frequently.

X Rinse with clean water and dry with a

chamois thoroughly. Do not allow cleaning agents to dry on the finish.

Automatic car wash G Warning! The vehicle is braked when the HOLD function or DISTRONIC PLUS is activated. Therefore, deactivate the HOLD function or DISTRONIC PLUS before the vehicle is washed in an automatic car wash. You can have your vehicle washed in an automatic car wash from the start. Brushless car washes are preferable. X To protect the filter system, activate the air

recirculation mode using rocker switch g on the climate control panel.

! Do not clean your vehicle in an automatic

touchless car wash which uses caustic spray. Caustic spray will damage the paint or ornamental moldings.

If the vehicle is very dirty, prewash it before running it through the automatic car wash. ! Make sure the combination switch is set to wiper setting $. Otherwise, the rain sensor could activate and cause the wipers to move unintentionally. This may lead to vehicle damage. Due to the width of the vehicle, fold in exterior rear view mirrors prior to running the vehicle through an automatic car wash to prevent damage to the mirrors.

X When taking the vehicle through an automatic conveyor-type car wash: Make sure the automatic transmission remains in neutral position N. Observe instructions, see “Remaining in neutral position N” (Y page 292).

When leaving the automatic car wash, make sure the mirrors are folded out. After running the vehicle through an automatic car wash, wipe any wax off of the windshield and the wiper blade inserts. This will prevent smears and reduce wiping noise which can be caused by residual wax on the windshield.

Ornamental moldings X For regular cleaning and care of ornamental

moldings, use a damp cloth.

! Do not use chrome cleaner on ornamental moldings. Although ornamental moldings may have chrome appearance, they could be made of anodized aluminum that will be damaged when cleaned with chrome cleaner. Instead, use a damp cloth to clean those ornamental moldings. For very dirty ornamental moldings of which you are sure are chrome-plated, use a chrome cleaner. If in doubt whether an ornamental molding is chrome-plated, contact an authorized Mercedes-Benz Center.

Headlamps, brake lamps, tail lamps, side markers, turn signal lenses X Use a mild vehicle wash detergent, such as

Mercedes-Benz approved Car Shampoo, with plenty of water.

By lining the seats with a proper intermediate cover, contact-discoloration will be prevented. G Warning! Only use seat covers which have been tested and approved by Mercedes-Benz for your vehicle model. Using other seat covers may interfere with or prevent the deployment of the side impact air bags. Contact an authorized Mercedes-Benz Center for availability. Leather upholstery Please note that leather upholstery is a natural product and is therefore subject to a natural aging process. Leather upholstery may also react to certain ambient influences such as high humidity or high temperature by showing wrinkles for example.
