! Because the ESP® 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 앫 the electronic parking brake is being tested

on a brake test dynamometer

앫 the vehicle is being towed with the

front/rear axle raised

Active braking action through the ESP® may oth- erwise seriously damage the brake system.

To help prevent brake disk corrosion after driving on wet road surfaces (particularly salted roads), it is advisable to brake the vehicle with considerable force prior to parking. The heat generated serves to dry the brakes. If your brake system is normally only sub- jected to moderate loads, you should occa- sionally 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.

Warning!

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

Refer to the description of the Brake Assist System (BAS or BAS Plus*) (컄 page 67). Brake pad wear or a leak in the system may be the reason for low brake fluid level in the reservoir. 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 (컄 page 611). Observe additional messages in the multifunction display that may appear (컄 page 622). 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 brake fluid recommended by Mercedes-Benz.

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.

! 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 brake pad 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 Lim- ited Warranty.

After hard braking, it is advisable to drive on for some time, rather than immediately park, so that the air stream can cool down the brakes faster.

Operation Driving instructions

High-performance brake system (CL 63 AMG and CL 65 AMG only) The high-performance brake system is de- signed to operate under the extremely high operating demands required to accommo- date the performance capabilities of the vehicle. The brakes may produce a squeak- ing-type noise depending on the 앫 vehicle speed 앫 brake force applied 앫 ambient conditions, e.g. temperature

and humidity

As with any brake system, the wear of indi- vidual 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 driv- ing style calling for high demand braking will cause your vehicle’s brakes to wear more quickly.

541

Operation Driving instructions

Warning!

Driving off

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 mes- sages in the multifunction display. Especial- ly for high performance driving, it is important to maintain and have the brake system checked regularly.

Apply the brakes to test them briefly after driving off. Perform this procedure only when the road is clear of other traffic. Warm up the engine smoothly. Do not place full load on the engine until the oper- ating 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 ESP® switched off. Doing so may cause serious damage to the drivetrain which is not covered by the Mercedes-Benz Limited War- ranty.

! Simultaneously depressing the accelerator pedal and applying the brakes reduces engine performance and causes premature brake wear and drivetrain wear.

Parking

Warning!

Do not park this vehicle in areas where com- bustible 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.

To reduce the risk of personal injury, or damage to the vehicle drivetrain, as a result of inadvertent vehicle movement, before turning off the engine and leaving the vehi- cle always: 앫 Keep right foot on brake pedal. 앫 Engage electronic parking brake. 앫 Shift the automatic transmission to P. 앫 Slowly release brake pedal. 앫 When parked on an incline, turn front

wheels towards the road curb.

542

Tires

Warning!

앫 Turn the SmartKey or the SmartKey with KEYLESS-GO* to starter switch position 0 and remove, or press the KEYLESS-GO* start/stop button.

앫 Take the SmartKey or the SmartKey with

KEYLESS-GO* with you and lock the vehicle when leaving.

Treadwear indicators (TWI) are required by law. These indicators are located in six places on the tread circumference and be- come visible at a tread depth of approxi- mately 1/16 in (1.6 mm), at which point the tire is considered worn and should be re- placed. The treadwear indicator appears as a solid band across the tread.

Warning!

If you feel a sudden significant vibration or ride disturbance, or you suspect that possi- ble damage to your vehicle has occurred, you should turn on the hazard warning flash- ers, carefully slow down, and drive with cau- tion to an area which is a safe distance from the road.

Inspect the tires and the vehicle underbody for possible damage. If the vehicle or tires appear unsafe, have the vehicle towed to the nearest Mercedes-Benz Center or tire dealer for repairs.

Although the applicable federal motor vehi- cle safety laws consider a tire to be worn when the treadwear indicators (TWI) be- come visible at approximately 1/16 in (1.6 mm), we recommend that you do not al- low your tires to wear down to that level. As tread depth approaches 1/8 in (3 mm), the adhesion properties on a wet road are sharply reduced.

Depending upon the weather and/or road surface (conditions), the tire traction varies widely.

Operation Driving instructions

Specified tire inflation pressures must be maintained. This applies particularly if the tires are subject to extreme operating con- ditions (e.g. high speeds, heavy loads, high ambient temperatures).

Warning!

Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You may lose control of the vehicle. Continued driving with a flat tire or driving at high speed with a flat tire will cause excessive heat build-up and possibly a fire.

For more information, see “Tires and wheels” (컄 page 561).

Hydroplaning

Depending on the depth of the water layer on the road, hydroplaning may occur, even at low speeds and with new tires. Reduce vehicle speed, avoid track grooves in the road and apply brakes cautiously in the rain.

543

Mercedes-Benz recommends winter tires (컄 page 590) with a minimum tread depth of approximately 1/6 in (4 mm) on all four wheels for the winter season to ensure normal balanced handling characteristics. On packed snow, they can reduce your stopping distance compared to summer tires. Stopping distance, however, is still consid- erably greater than when the road is not covered with snow or ice. Exercise appro- priate caution.

! Avoid spinning of a drive wheel. This may cause serious damage to the drivetrain which is not covered by the Mercedes-Benz Limited War- ranty.

Tire speed rating

Regardless of the tire speed rating, local speed limits should be obeyed. Use pru- dent driving speeds appropriate to prevail- ing conditions.

Warning!

Even when permitted by law, never operate a vehicle at speeds greater than the maxi- mum speed rating of the tires.

Exceeding the maximum speed for which tires are rated can lead to sudden tire fail- ure, causing loss of vehicle control and pos- sibly resulting in an accident and/or serious personal injury and possible death, for you and for others.

Operation Driving instructions

Tire traction

The safe speed on a wet, snow covered or icy road is always lower than on a dry road. You should pay particular attention to the condition of the road whenever the outside temperatures are close to the freezing point.

Warning!

If ice has formed on the road, tire traction will be substantially reduced. Under such weather conditions, drive, steer and brake with extreme caution.

544

For information on how to identify the tire speed rating on a tire’s sidewall, see “Tire size designation, load and speed rating” (컄 page 577). If you are uncertain about the correct read- ing of the information given on a tire’s side- wall, any authorized Mercedes-Benz Center will be glad to assist you.

i For information on speed ratings for winter tires, see (컄 page 580) and (컄 page 590).

An electronic speed limiter prevents your vehicle from exceeding a speed of 앫 All models except AMG vehicles:

130 mph (210 km/h)

앫 CL 63 AMG: CL 65 AMG: 155 mph (250 km/h)

앫 CL 63 AMG with increased top speed*:

CL 63 AMG (Performance Package*): CL 65 AMG with increased top speed*: 186 mph (300 km/h)

The factory equipped tires on your vehicle may have a tire speed rating above the maximum speed permitted by the elec- tronic speed limiter. Make sure your tires have the required tire speed rating as specified for your vehicle in the “Technical data” section (컄 page 727), for example when purchasing new tires.

Operation Driving instructions

Winter driving instructions

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, move gear selector lever 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” (컄 page 591).

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.

545

Operation Driving instructions

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.

Warning!

Standing water

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.

! 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 wa- ter into the engine and auxiliary equipment, thus damaging them. If you must drive through standing water, drive slowly to prevent water from entering the pas- senger compartment or the engine compart- ment. Water in these areas could cause damage to electrical components or wiring of the engine or transmission, or could result in water being in- gested by the engine through the air intake caus- ing severe internal engine damage. Any such damage is not covered by the Mercedes-Benz Limited Warranty.

Warning!

Warning!

Make sure not to endanger any other road users when carrying out these braking maneuvers.

546

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 590).

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 transmitters

COMAND, radio, and telephone*

Warning!

Please do not forget that your primary re- sponsibility 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. Otherwise, you may not be able to observe traffic conditions and could endanger yourself and others.

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

1 Observe all legal requirements.

Telephones and two-way radios

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 antenna.

547

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 parts of the engine and the emis- sion control system serve to keep the toxic components of the exhaust gases within permissible limits required by law. These systems will function properly only when maintained strictly according to fac- tory specifications. Any adjustments on the engine should, therefore, be carried out only by qualified Mercedes-Benz Cen- ter authorized technicians. Engine adjustments should not be altered in any way. The specified service proce- dures must be carried out regularly accord- ing to Mercedes-Benz servicing requirements. For details please refer to the Maintenance Booklet.

Operation Driving instructions

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 Maintenance Booklet.

! To prevent damage to the catalytic convert- ers, only use premium unleaded gasoline in this vehicle. Any noticeable irregularities in engine operation should be repaired promptly. Otherwise, exces- sive unburned fuel may reach the catalytic con- verter, causing it to overheat and potentially start a fire.

548

Warning!

Coolant temperature

Inhalation of exhaust gas is hazardous to your health. All exhaust gas contains carbon monoxide (CO), and inhaling it can cause un- consciousness and possible 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 only with at least one win- dow fully open at all times.

During severe operating conditions, e.g. stop-and-go traffic, the coolant tem- perature may rise close to approximately 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.

Operation Driving instructions

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.

Stop the vehicle in a safe location away from other traffic. Turn off the engine, get out of the vehicle and do not stand near the vehicle until the engine has cooled down.

왔 Tires and wheels Contact an 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.

Warning!

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

components can be damaged.

앫 The operating clearance of the wheels and the tires may no longer be correct.

Warning!

Worn, old tires can cause accidents. If the tire tread is worn to minimum tread depth, or if the tires have sustained damage, re- place them.

When replacing rims, only use 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.

Retreaded tires are not tested or recom- mended by Mercedes-Benz, since previous damage cannot always be recognized on re- treads. The operating safety of the vehicle cannot be assured when such tires are used.

Operation Tires and wheels

Important guidelines

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 inflation pressure loss and damage to the tire beads.

앫 If vehicle is heavily loaded, check tire

inflation 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 of less than 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).

561

Tire inspection Every time you check the tire inflation pressure, you should also inspect your tires for the following: 앫 excessive treadwear (컄 page 563) 앫 cord or fabric showing through the

tire’s rubber

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

앫 bumps, bulges, cuts, cracks or splits in

the tread or side of the tire

Warning!

Tires and spare tire should be replaced after 6 years, regardless of the remaining tread.

Replace the tire if you find any of the above conditions. Make sure you also inspect the spare tire periodically for condition and inflation. Spare tires will age and degrade over time even if never used, and thus should be in- spected and replaced when necessary.

Operation Tires and wheels

Tire care and maintenance

Warning!

Regularly check the tires for damage. Dam- aged tires can cause tire inflation pressure loss. As a result, you could lose control of your vehicle.

Worn, old tires can cause accidents. If the tire tread is badly worn, or if the tires have sustained damage, replace them.

Regularly check the tire inflation pressure at least once a month. For more informa- tion on checking tire inflation pressure, see “Recommended tire inflation pres- sure” (컄 page 569).

562

Tread depth Do not allow your tires to wear down too far. Adhesion properties on wet roads are sharply reduced at tread depths of less than 1/8 in (3 mm). Treadwear indicators (TWI) are required by law. These indicators are located in six places on the tread circumference and become visible at a tread depth of approx- imately 1/16 in (1.6 mm), at which point the tire is considered worn and should be re- placed. Recommended minimum tire tread depth: 앫 Summer tires 1/8 in (3 mm) 앫 Winter tires 1/6 in (4 mm)

Warning!

Although the applicable federal motor safety laws consider a tire to be worn when the treadwear indicators (TWI) become visible at approximately 1/16 in (1.6 mm), we recom- mend that you do not allow your tires

to wear down to that level. As tread depth approaches 1/8 in (3 mm), the adhesion properties on a wet road are sharply reduced.

Depending upon the weather and/or road surface (conditions), the tire traction varies widely.

Operation Tires and wheels

Storing tires

! Keep unmounted tires in a cool, dry place with as little exposure to light as possible. Pro- tect tires from contact with oil, grease and gaso- line.

Cleaning tires

! Never use a round nozzle to power wash tires. The intense jet of water can result in dam- age to the tire. Always replace a damaged tire.

1 TWI (TreadWear Indicator) The treadwear indicator appears as a solid band across the tread.

Direction of rotation

Loading the vehicle

Unidirectional tires offer added advan- tages, 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 intended direction of rotation (spinning) of the tire.

i Spare wheels may be mounted against the direction of rotation (spinning) even with a unidi- rectional tire for temporary use only until the reg- ular drive wheel has been repaired or replaced. Always observe and follow applicable temporary use restrictions and speed limitations indicated on the spare wheel.

Two labels on your vehicle show how much weight it may properly carry. 1) The Tire and Loading Information

placard can be found on the driver’s door B-pillar. This Tire and Loading Information placard tells you important information about the number of peo- ple that can be in the vehicle and the total weight that can be carried in the vehicle. It also contains information on the proper size and recommended tire inflation pressures for the original equipment tires on your vehicle.

2) The certification label, also found on

the driver’s door B-pillar tells you about the gross weight capacity of your vehi- cle, called the Gross Vehicle Weight Rating (GVWR). The GVWR includes the weight of the vehicle, all occupants, fuel and cargo. The certification label also tells you about the front and rear axle weight capacity, called the Gross Axle Weight Rating (GAWR). The GAWR

564

is the total allowable weight that can be carried by a single axle (front or rear). Never exceed the GVWR or GAWR for either the front axle or rear axle.

load from your trailer will be trans- ferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity of your vehicle (컄 page 568).

The following table shows examples on how to calculate total and cargo load capacities with varying seating configura- tions and number and size of occupants. The following examples use a load limit of 1500 lbs. This is for illustration purposes only. Make sure you are using the actual load limit for your vehicle stated on the vehicle’s Tire and Loading Informa- tion placard (컄 page 565).

driver and passengers that will be riding in your vehicle.

Step 3
왘 Subtract the combined weight of the

driver and passengers from XXX kilograms or XXX lbs.

Step 4
왘 The resulting figure equals the avail-

able amount of cargo and luggage load capacity. For example, if the “XXX” amount equals 1400 lbs and there will be five 150 lbs passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs (1400 – 750 (5 x 150) = 650 lbs).

Step 5
왘 Determine the combined weight of

luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in step 4.

Certification label Even after careful determination of the combined weight of all occupants, cargo and the trailer tongue load (if applicable) (컄 page 568) as to not exceed the permis- sible load limit, you must make sure that your vehicle never exceeds the Gross Vehi- cle Weight Rating (GVWR) and the Gross Axle Weight Rating (GAWR) for either the front or rear axle. You can obtain the GVWR and GAWR from the certification label. The certification label can be found on the driver’s door B-pillar, see “Technical data” (컄 page 722).

Gross Vehicle Weight Rating (GVWR): The total weight of the vehicle, all occupants, all cargo, and the trailer tongue load (컄 page 568) must never exceed the GVWR. Gross Axle Weight Rating (GAWR): The to- tal allowable weight that can be carried by a single axle (front or rear). To assure that your vehicle does not ex- ceed the maximum permissible weight limits (GVWR and GAWR for front and rear axle), have the loaded vehicle (including driver, passengers and all cargo and, if applicable, trailer fully loaded) weighed on a suitable commercial scale.

Trailer tongue load The tongue load of any trailer is an impor- tant weight to measure because it affects the load you can carry in your vehicle. If a trailer is towed, the tongue load must be added to the weight of all occupants riding and any cargo you are carrying in the vehicle. The tongue load typically is 10% of the trailer weight and everything loaded in it. Your Mercedes-Benz has been designed primarily to carry passengers and their cargo. Mercedes-Benz does not recom- mend trailer towing with your vehicle.

Recommended tire inflation pressure

Warning!

Follow recommended tire inflation pressures.

Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affect handling and fuel economy, and are more likely to fail from being over- heated.

Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes etc.

Do not overload the tires by exceeding the specified load limit as indicated on the Tire and Loading Information placard on the driver’s door B-pillar. Overloading the tires can overheat them, possibly causing a blowout. Overloading the tires can also result in handling or steering problems, or brake failure.

Your vehicle is equipped with the Tire and Loading Information placard located on the driver’s door B-pillar (컄 page 564). The tire inflation pressure should be checked regularly and should only be ad- justed on cold tires. The tires can be con- sidered cold if the vehicle has been parked for at least 3 hours or driven less than 1 mile (1.6 km). Follow recommended cold tire inflation pressures listed on the Tire and Loading Information placard on the driver's door B-pillar.

Operation Tires and wheels

Keeping the tires properly inflated provides the best handling, tread life and riding comfort. In addition to the Tire and Loading Information placard on the driver’s door B-pillar, also consult the tire inflation pressure label (if available) on the fuel filler flap (컄 page 550) for any additional infor- mation pertaining to special driving situa- tions. For more information, see “Important notes on tire inflation pressure” (컄 page 570).

Important notes on tire inflation pressure

Warning!

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

foreign objects.

앫 Check to see whether air is leaking from

the valves or from around the rim.

Tire temperature and tire inflation pressure are also increased while driving, depending on the driving speed and the tire load. If you will be driving your vehicle at high speeds of 100 mph (160 km/h) or higher, where it is legal and conditions allow, consult the tire inflation pressure label on the inside of the fuel filler flap (if available) on how to adjust the cold tire inflation pressure. If you do not adjust the tire infla- tion pressure, excessive heat can build up and result in sudden tire failure.

If your vehicle is not equipped with the tire inflation pressure label on the inside of the fuel filler flap, contact an authorized Mercedes-Benz Center for proper tire inflation pressure.

i Driving comfort may be reduced when the tire inflation pressure is adjusted to the value for speeds above 100 mph (160 km/h) as specified on the tire inflation pressure label located on the inside of the fuel filler flap.

Be sure to readjust the tire inflation pressure for normal driving speeds. You should wait until the tires are cold before adjusting the tire inflation pressure. Some vehicles may have supplemental tire inflation pressure information for vehicle loads less than the maximum loaded vehi- cle condition (컄 page 577). If such infor- mation is provided, it can be found on the tire inflation pressure label (if available) located on the inside of the fuel filler flap (컄 page 550).

Tire inflation pressure changes by approxi- mately 1.5 psi (0.1 bar) per 18°F (10°C) of air temperature change. Keep this in mind when checking tire inflation pressure where the temperature is different from the outside temperature.

Checking tire inflation pressure

Regularly check your tire inflation pressure at least once a month. Check and adjust the tire inflation pressure when the tires are cold. The tires can be considered cold if the vehicle has been parked for at least 3 hours or driven less than 1 mile (1.6 km). If you check the tire inflation pressure when the tires are warm (the vehicle has been driven for several miles or sitting less than 3 hours), the reading will be approximately 4 psi (0.3 bar) higher than the cold reading. This is normal. Do not let air out to match the specified cold tire in- flation pressure. Otherwise, the tire will be underinflated.

Warning!

Follow recommend tire inflation pressures.

Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adverse- ly affect handling and fuel economy, and are more likely to fail from being overheated.

Do not overinflate tires. Overinflated tires can adversely affect handling and ride com- fort, wear unevenly, increase stopping dis- tance, and result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road de- bris, potholes etc.

Do not overload the tires by exceeding the specified load limit as indicated on the Tire and Loading Information placard on the driv- er’s door B-pillar. Overloading the tires can overheat them, possibly causing a blowout. Overloading the tires can also result in han- dling or steering problems, or brake failure.

Operation Tires and wheels

Checking tire inflation pressure manually Follow the steps below to achieve correct tire inflation pressure: 왘 Remove the cap from the valve on one

tire.

왘 Firmly press a tire gauge onto the

valve.

왘 Read tire inflation pressure on tire gauge and check against the recom- mended tire inflation pressure on the Tire and Loading Information placard on the driver’s door B-pillar (컄 page 564) or, if available, the tire in- flation pressure label on the inside of the fuel filler flap. If necessary, add air to achieve the recommended tire infla- tion pressure.

i If you have overfilled the tire, release tire in- flation pressure by pushing the metal stem of the valve with e.g. a tip of a pen. Then recheck the tire inflation pressure with the tire gauge. 왘 Install the valve cap. 왘 Repeat this procedure for each tire.

Checking tire pressure electronically with the Advanced Tire Pressure Monitoring System (Advanced TPMS)

i The Advanced Tire Pressure Monitoring System (Advanced TPMS) is equipped with a combination low tire pressure/TPMS malfunc- tion telltale in the instrument cluster (컄 page 618). Depending on how the telltale illu- minates, it indicates a low tire inflation pressure condition or a malfunction in the Advanced TPMS system itself: 앫 If the telltale illuminates continuously, one or more of your tires is significantly underin- flated. There is no malfunction in the Advanced TPMS.

앫 USA only:

If the telltale flashes for 60 seconds and then stays illuminated, the Advanced TPMS system itself is not operating properly.

572

i USA only: This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful

interference, and

(2) this device must accept any interference received, including interference that may cause undesired operation.

Any unauthorized modification to this device could void the user’s authority to operate the equipment.

i Canada only: This device complies with RSS-210 of Industry Canada. Operation is subject to the following two conditions: (1) This device may not cause interference, and (2) this device must accept any interference received, including interference that may cause undesired operation of the device. Any unauthorized modification to this device could void the user’s authority to operate the equipment.

The Advanced TPMS only functions on wheels that are equipped with the proper electronic sensors. It monitors the tire in- flation pressure, as selected by the driver, in all four tires. A warning is issued to alert you to a decrease in pressure in one or more of the tires. Tire inflation pressure inquiries are made using the multifunction display. The present inflation pressures are displayed only after a few minutes of travel time.

i Possible differences between the readings of a tire inflation pressure gauge of an air hose, e.g. gas station equipment, and the vehicle’s control system can occur. Usually the readings issued by the control system are more precise.

i When the message “Tire Pressures Dis- played After Driving a Few Minutes” appears in the display, the individual inflation pressure val- ues are matched with the tires. The individual values are displayed after a few minutes driving.

Warning!

It is the driver’s responsibility to calibrate the Advanced TPMS on the recommended cold inflation pressure. Underinflated tires affect the ability to steer or brake the vehi- cle. You might lose control over the vehicle.

i With a spare wheel without wheel sensor mounted, the system may still indicate the tire inflation pressure of the removed wheel for some minutes. If this happens, keep in mind that the indicated value where the spare wheel is mount- ed does not reflect the actual spare tire inflation pressure.

Operation Tires and wheels

Warning!

The Advanced TPMS does not indicate a warning for wrongly selected inflation pres- sures. Always adjust tire inflation pressure according to the Tire and Loading Informa- tion placard on the driver’s door B-pillar or, if available, the supplemental tire inflation pressure information on the inside of the fuel filler flap.

The Advanced TPMS is not able to issue a warning due to a sudden dramatic loss of pressure (e.g. tire blowout caused by a for- eign object). In this case bring the vehicle to a halt by carefully applying the brakes and avoiding abrupt steering maneuvers.

the system may not be able to detect or sig- nal low tire pressure as intended.

Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recom- mended by the vehicle manufacturer on the Tire and Loading Information placard on the driver’s door B-pillar or, if available, the tire inflation pressure label on the fuel filler flap. If your vehicle has tires of a different size than the size indicated on the Tire and Loading Information placard or, if available, the tire inflation pressure label, you should determine the proper tire inflation pressure for those tires. As an added safety feature, your vehicle has been equipped with an advanced tire pres- sure monitoring system (Advanced TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significant- ly underinflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possi- ble, and inflate then to the proper pressure. Driving on a significantly underinflated tire

574

Underinflation also reduces fuel efficiency and tire tread life, and may effect the vehi- cle’s handling and stopping ability. Please note that the Advanced TPMS is not a sub- stitute for proper tire maintenance, and it is the driver’s responsibility to maintain cor- rect tire pressure, even if underinflation has not reached the level to trigger illumination of the Advanced TPMS low tire pressure tell- tale.

USA only: Your vehicle has also been equipped with an Advanced TPMS malfunction indicator to in- dicate when the system is not operating properly. The Advanced TPMS malfunction indicator is combined with the low tire pres- sure telltale. When the system detects a malfunction, the telltale will flash for approx- imately one minute and then remain contin- uously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is illuminated,

Advanced TPMS malfunctions may occur for a variety of reasons, including the installa- tion of replacement or alternate tires or wheels on the vehicle that prevent the Ad- vanced TPMS from functioning properly. Al- ways check the Advanced TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to en- sure that the replacement or alternate tires and wheels allow the Advanced TPMS to continue to function properly.

i If a condition causing the Advanced TPMS to malfunction develops, it may take up to 10 minutes for the system to signal a malfunc- tion using the Advanced TPMS telltale flashing and illumination sequence. The telltale extinguishes after a few minutes driv- ing if the malfunction has been corrected.

i Operating radio transmission equipment (e.g. wireless headsets, two-way radios) in or near the vehicle could cause the Advanced TPMS to malfunction.

Reactivating Advanced TPMS The Advanced TPMS must be reactivated when you have adjusted the tire inflation pressure to a new level (e.g. because of dif- ferent load or driving conditions). The Ad- vanced TPMS is then recalibrated to the current tire inflation pressures.

Warning!

It is the driver’s responsibility to calibrate the Advanced TPMS on the recommended cold inflation pressure. Underinflated tires affect the ability to steer or brake the vehi- cle. You might lose control over the vehicle.
