when the indicator lamp does not come on in red or stays on longer than ap- proximately 10 seconds. If the indicator lamp in the Information button ¡ is illuminated continuous- ly and no voice connection to the Response Center was established, then the Tele Aid system could not initiate an Information call (e.g. the relevant cellular phone network is not avail- able). The message CALL FAILED ap- pears in the multifunction display.

Information calls can be terminated us- ing the t button on the multifunc- tion steering wheel or the respective button for ending a telephone call on the COMAND head unit.

If the indicator lamps do not start flash- ing after pressing one of the buttons or remain illuminated (in red) at any time, the Tele Aid system has detected a fault or the service is not currently ac- tive, and may not initiate a call. Visit an Mercedes-Benz Center and have the system checked or contact the Response Center at 1-800-756-9018 (in the USA) or 1-888-923-8367 (in Canada) as soon as possible.

Call priority If other service calls such as a Roadside Assistance call or Information call are ac- tive, an emergency call is still possible. In this case, the emergency call will take pri- ority and override all other active calls.

The indicator lamp in the respective button flashes until the call is con- cluded. Calls can only be terminated by a Response Center or Customer Assistance Center representative except Roadside Assistance and Information calls, which can also be terminated by pressing button t on the multifunction steering wheel or the respective button for ending a telephone call on the COMAND head unit.

Garage door opener

The integrated remote control is capable of operating up to three separately controlled devices. It provides a convenient way to re- place up to three hand-held remote con- trols used to operate devices such as garage door openers, gate openers, or oth- er devices compatible with HomeLink® or some other systems. Before the integrated remote control can be used, it must be programmed to the ga- rage door opener, gate operator or other device you wish to operate. See the follow- ing instructions for programming informa- tion.

Stolen Vehicle Recovery services In the event your vehicle was stolen: 왘 Report the incident to the police. The police will issue a numbered incident report.

왘 Pass this number on to the

Mercedes-Benz Response Center along with your password issued to you when you subscribed to the service. The Response Center will then attempt to covertly contact the vehicle’s Tele Aid system. Once the vehicle is located, the Response Center will contact the local law enforcement and you. The vehicle’s location will only be provided to law enforcement.

When the anti-theft alarm or the tow-away alarm stays on for more than 30 seconds, a call is initiated automat- ically to the Response Center. See anti-theft alarm system (컄 page 85) and tow-away alarm (컄 page 87).

Warning!

When programming a garage door opener, it is advised to park outside the garage.

Do not run the engine while programming the integrated remote control. Inhalation of exhaust gas is hazardous to your health. All exhaust gas contains carbon monoxide, and inhaling it can cause unconsciousness and possible death.

Programming the integrated remote control Step 1: 왘 Switch on the ignition (컄 page 34).

Before programming the integrated remote control to a garage door opener or gate operator, make sure people and objects are out of the way of the device to prevent po- tential harm or damage. When programming a garage door opener, the door moves up or down. When programming a gate operator, the gate opens or closes.

Do not use the integrated remote control with any garage door opener that lacks safety stop and reverse features as required by U.S. federal safety standards (this includes any garage door opener model manufactured before April 1, 1982). A garage door that cannot detect an object - signaling the door to stop and reverse - does not meet current U.S. federal safety standards.

250

Step 2: 왘 If you have previously programmed an signal transmitter button and wish to retain its programming, proceed to step 3. If you are programming the integrated remote control for the first time, press and hold the two outer signal transmit- ter buttons 2 and 4 and release them only when the indicator lamp 1 begins to flash after approximately 20 seconds (do not hold the button for longer than 30 seconds). This proce- dure erases any previous settings for all three channels and initializes the memory. If you later wish to program a second and/or third hand-held transmitter to the remaining two signal transmitter buttons, do not repeat this step and be- gin directly with step 3.

Controls in detail Useful features

Step 3: 왘 Hold the end of the hand-held remote

control 5 of the device you wish to train approximately 2 to 5 in (5 to12 cm) away from the signal trans- mitter button (2, 3 or 4) to be pro- grammed, while keeping the indicator lamp 1 in view.

Step 4: 왘 Using both hands, simultaneously

press the hand-held remote control button 6 and the desired signal trans- mitter button (2, 3 or 4). Do not release the buttons until step 5 is com- pleted. The indicator lamp 1 will flash, first slowly and then rapidly.

The indicator lamp 1 flashes immedi- ately the first time the signal transmit- ter button is programmed. If this button has already been programmed, the in- dicator lamp will only start flashing af- ter 20 seconds.

Step 5: 왘 After the indicator lamp 1 changes from a slow to a rapidly flashing light, release the hand-held remote control button and the signal transmitter but- ton. Step 6: 왘 Press and hold the just-trained signal transmitter button (2, 3 or 4) and observe the indicator lamp 1.

If the indicator lamp 1 stays on constantly, programming is complete and your device should activate when the respective signal transmitter button (2, 3 or 4) is pressed and re- leased.

If the indicator lamp 1 flashes rapidly for about 2 seconds and then turns to a constant light, continue with programming steps 8 through 12 as your garage door opener may be equipped with the “rolling code” feature.

Step 7: 왘 To program the remaining two signal transmitter buttons, repeat the steps above starting with step 3.

251

Controls in detail Useful features

Rolling code programming To train a garage door opener (or other rolling code devices) with the rolling code feature, follow these instructions after completing the “Programming” portion (steps 1 through 6) of this text. (A second person may make the following training procedures quicker and easier.) Step 8: 왘 Locate “training” button on the garage

door opener motor head unit. Exact location and color of the button may vary by garage door opener brand. Depending on manufacturer, the “training” button may also be referred to as “learn”or “smart” button. If there is difficulty locating the transmitting button, refer to the garage door opener operator’s manual.

252

Step 9: 왘 Press the “training” button on the ga-

rage door opener motor head unit. The “training light” is activated.

You have 30 seconds to initiate the follow- ing two steps. Step 10: 왘 Return to the vehicle and firmly press, hold for 2 seconds and release the pro- grammed signal transmitter button (2, 3 or 4).

Step 11: 왘 Press, hold for 2 seconds and release same signal transmitter button a sec- ond time to complete the training pro- cess.

Some garage door openers (or other rolling code equipped devices) may require you to press, hold for 2 seconds and release the same signal transmit- ter button a third time to complete the training process.

Step 12: 왘 Confirm the garage door operation by pressing the programmed signal trans- mitter button (2, 3 or 4).

Step 13: 왘 To program the remaining two signal transmitter buttons, repeat the steps above starting with step 3.

왘 While still holding down the signal transmitter button (2, 3 or 4), “cycle” your hand-held remote control button 6 as follows: Press and hold button 6 for 2 seconds, then release it for 2 seconds, and again press and hold it for 2 seconds. Repeat this se- quence on the hand-held remote con- trol until the frequency signal has been learned. Upon successful training, the indicator lamp 1 will flash slowly and then rapidly after several seconds.

왘 Proceed with programming step 5 and

step 6 to complete.

Gate operator/Canadian programming Canadian radio-frequency laws require transmitter signals to “time-out” (or quit) after several seconds of transmission which may not be long enough for the integrated signal transmitter to pick up the signal during programming. Similar to this Canadian law, some U.S. gate operators are designed to “time-out” in the same manner. If you live in Canada or if you are having difficulties programming a gate operator (regardless of where you live) by using the programming procedures, replace step 4 with the following: Step 4: 왘 Press and hold the signal transmitter button (2, 3 or 4). Do not release this button until it has been successful- ly trained.

Controls in detail Useful features

Upon completion of programming the integrated remote control, make sure you retain the hand-held remote con- trol that came with the garage door opener, gate operator or other device. You may need it for use in other vehi- cles, for future programming of an integrated remote control, or simply for continued use as a hand-held remote control to operate the respective device in other situations.

Controls in detail Useful features

Reprogramming a single signal trans- mitter button To program a device using a signal trans- mitter button previously trained, follow these steps: 왘 Switch on the ignition (컄 page 34). 왘 Press and hold the desired signal transmitter button (2, 3 or 4). Do not release the button.

왘 The indicator lamp 1 will begin to

flash after 20 seconds. Without releas- ing the signal transmitter button, pro- ceed with programming starting with step 3.

Operation of integrated remote control 왘 Switch on the ignition (컄 page 34). 왘 Select and press the appropriate inte- grated signal transmitter button (2, 3 or 4) to activate the remote con- trolled device. The integrated remote control trans- mitter continues to send the signal as long as the button is pressed – up to 20 seconds.

Erasing the integrated remote control memory 왘 Switch on the ignition (컄 page 34). 왘 Simultaneously press and hold down

the outer signal transmitter buttons 2 and 4, for approximately 20 seconds, until the indicator lamp 1 flashes rap- idly. Do not hold for longer than 30 seconds. The codes of all three channels are erased.

If you sell your vehicle, erase the codes of all three channels.

Programming tips If you are having difficulty programming the integrated remote control, here are some helpful tips: 앫 Check the frequency of the hand-held remote control 5 (typically located on the reverse side of the remote). The in- tegrated remote control is compatible with radio-frequency devices operating between 288-399 MHz.

앫 Put a new battery in the hand-held re- mote control 5. This will increase the likelihood of the hand-held remote con- trol sending a faster and more accurate signal to the integrated remote control.

앫 While performing step 3, hold the

hand-held remote control 6 at differ- ent lengths and angles from the signal transmitter button (2, 3 or 4) you are programming. Attempt varying an- gles at the distance of 2 to 5 inches (5 to 12 cm) away or the same angle at varying distances.

앫 If another hand-held remote control is available for the same device, try the programming steps again using that other hand-held remote control. Make sure new batteries are in the hand-held remote control before beginning the procedure.

앫 Straighten the antenna wire from the

garage door opener assembly. This may help improve transmitting and/or receiving signals.

Certain types of garage door openers are incompatible with the integrated remote control. If you should experi- ence further difficulties with program- ming the integrated remote control, contact an authorized Mercedes-Benz Center, or call Mercedes-Benz Customer Assistance Center (in the USA only) at 1-800-FOR-MERCedes, or Customer Service (in Canada) at 1-800-387-0100.

Operation The first 1000 miles (1500 km)

In the “Operation” section you will find de- tailed information on operating, maintain- ing and caring for your vehicle.

258

The more cautiously you treat your vehicle during the break-in period, the more satis- fied you will be with its performance later on. 앫 Drive your vehicle during the first

1000 miles (1500 km) at varying but moderate vehicle and engine speeds. 앫 During this period, avoid heavy loads (full throttle driving) and excessive en- gine speeds (no more than 2/3 of max- imum rpm in each gear).

앫 Avoid accelerating by kick-down. 앫 Do not attempt to slow the vehicle

down by shifting to a lower gear using the gear selector lever.

앫 Select positions 3, 2 or 1 only when driving at moderate speeds (for hill driving).

앫 Select C as the preferred shift program (컄 page 171) for the first 1000 miles (1500 km).

After 1000 miles (1500 km), you may gradually increase vehicle and engine speeds to the permissible maximum.

Additional instructions for AMG vehi- cles: 앫 During the first 1000 miles

(1500 km), do not exceed a speed of 85 mph (140 km/h).

앫 During this period, avoid engine

speeds above 4500 rpm (CL 55 AMG) or 4000 rpm (CL 65 AMG) in each gear.

All of the above instructions, as may apply to your vehicle type, also apply when driv- ing the first 1000 miles (1500 km) after the engine or the rear differential has been replaced.

Always obey applicable speed limits.

Operation Driving instructions

Fuel consumption is also increased by driv- ing in cold weather, in stop-and-go traffic, on short trips, and in hilly area.

Pedals

Warning!

Drinking and driving

Warning!

Keep driver’s foot area clear at all times. Ob- jects stored in this area may impair pedal movement.

Drinking and driving and/or taking drugs and driving are very dangerous combina- tions. Even a small amount of alcohol or drugs can affect your reflexes, perceptions and judgment.

The possibility of a serious or even fatal ac- cident 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.

Power assistance

Warning!

With the engine not running, there is no power assistance for the brake 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 ve- hicle.

왔 Driving instructions Drive sensibly – save fuel

Fuel consumption, to a great extent, de- pends on driving habits and operating con- ditions. To save fuel you should: 앫 Keep tires at the recommended tire

inflation pressures.

앫 Remove unnecessary loads. 앫 Remove roof rack when not in use. 앫 Allow engine to warm up under low

load use.

앫 Avoid frequent acceleration and decel-

eration.

앫 Have all maintenance work performed

at the intervals specified in the Maintenance Booklet and as required by the Maintenance System (U.S. vehicles) or FSS (Canada vehi- cles). Contact an authorized Mercedes-Benz Center.

259

Operation Driving instructions

Brakes

Warning!

After driving in heavy rain for some time without applying the brakes or through wa- ter deep enough to wet brake components, the first braking action may be somewhat reduced and increased pedal pressure may be necessary to obtain expected braking ef- fect. Maintain a safe distance from vehicles in front.

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 effec- tiveness. It may not be possible to stop the vehicle in sufficient time to avoid an acci- dent.

260

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) (컄 page 81).

If the parking brake is released and the brake warning lamp in the instrument clus- ter stays on, the brake fluid level in the res- ervoir is too low. Brake pad wear or a leak in the system may be the reason for low brake fluid in the res- ervoir. Have the brake system inspected immedi- ately. 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 pre- vent overheating of the brakes and re- duces brake pad wear.

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.

High-performance brake system (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.

Operation Driving instructions

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

261

Operation Driving instructions

Driving off

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 starting off on a slippery surface, do not allow a drive wheel to spin for an ex- tended period with the ESP® switched off. Doing so may cause serious damage to the drivetrain which is not covered by the Mercedes-Benz Limited Warranty.

Simultaneously depressing the acceler- ator pedal and applying the brake re- duces engine performance and causes premature brake and drivetrain wear.

262

앫 Turn the SmartKey to starter switch

position 0 and remove, or press KEYLESS-GO* start/stop button (컄 page 35).

앫 Take the SmartKey or the SmartKey with KEYLESS-GO* with you and lock vehicle when leaving.

Set the parking brake whenever park- ing or leaving the vehicle. In addition, move the gear selector lever to position P. When parking on hills, always turn front wheels towards the road curb.

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 as a re- sult of inadvertent vehicle movement, before turning off the engine and leaving the vehicle always: 앫 Keep right foot on brake pedal. 앫 Firmly depress parking brake pedal. 앫 Move the gear selector lever to

position P.

앫 Slowly release brake pedal. 앫 When parked on an incline, turn front

wheel towards the road curb.

Operation Driving instructions

The treadwear indicator appears as a solid band across the tread.

Warning!

Tires

Warning!

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.

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.

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.

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).

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.

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.

263

Mercedes-Benz recommends winter tires (컄 page 313) 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 considerably greater than when the road is not covered with snow or ice. Exercise ap- propriate caution.

Avoid spinning of a drive wheel. This may cause serious damage to the driv- etrain which is not covered by the Mercedes-Benz Limited Warranty.

Tire speed rating

Regardless of the tire rating, local speed limits should be obeyed. Use prudent driv- ing speeds appropriate to prevailing condi- tions.

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.

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 system under such conditions. When the vehicle is in danger of skidding, move the gear selector lever to position N. Try to keep the vehicle under control by corrective steering action.

For information on driving with snow chains, see “Snow chains” (컄 page 314).

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.

265

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.

Warning!

Warning!

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

266

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 313).

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.

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.

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 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 potentially start a fire.

268

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 Maintenance Booklet.

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 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 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.

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.

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 See 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. See 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 badly worn, or if the tires have sustained damage, replace 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 retreads. 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 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).

283

Tire inspection Every time you check your tire inflation pressure, you should also inspect your tires for the following: 앫 excessive treadwear (컄 page 285) 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 become worn over time even if never used, and thus should be inspected 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 your 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 292).

284

Tread depth 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). 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 replaced. 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 tread wear indicators (TWI) become visible at approximately 1/16 in (1.6 mm), we rec- ommend 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 re- duced.

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

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