The Tele Aid system (Telematic Alarm Identification on De- mand) The Tele Aid system consists of three types of response: 앫 automatic and manual emergency 앫 roadside assistance and 앫 information The Tele Aid system is operational provid- ing that the vehicle’s battery is charged, properly connected, not damaged and cellular and GPS coverage is available. The speaker volume of a Tele Aid call can be adjusted when using the volume control on the multifunction steering wheel. To raise, press button æ and to lower, press button ç. The volume can also be adjusted using the volume knob on your audio system or COMAND* head unit. 왘 To activate, press the SOS button, the

Roadside Assistance button • or the Information button ¡, depend- ing on the type of response required.

262

The SOS button is located above the in- side rear view mirror. The Roadside Assistance button • and the Information button ¡ are located below the center armrest cover.

Shortly after the completion of your Tele Aid acquaintance call, you will receive a user ID and password. By visiting www.mbusa.com and selecting “Tele Aid” (USA only), you will have access to account information, remote door unlock and more.

The Tele Aid system utilizes the cellular network for communication and the GPS (Global Positioning System) satel- lites for vehicle location. If either of these signals are unavailable, the Tele Aid system may not function and if this occurs, assistance must be sum- moned by other means.

Warning!

If the indicator lamps in the SOS button, in the Roadside Assistance button and/or in the Information button remain illuminated constantly in red and/or the message Tele Aid malfunction. Drive to workshop is displayed in the multifunction display after the system self-check, a mal- function in the system has been detected.

If a malfunction is indicated as outlined above, the system may not operate as expected. Have the system checked at the nearest Mercedes-Benz Center as soon as possible.

Emergency calls An emergency call is initiated automatical- ly following an accident in which the emer- gency tensioning devices (ETDs) or air bags deploy. An emergency call can also be initiated manually by opening the cover next to the interior rear view mirror labeled SOS, then briefly pressing the button located under the cover. See (컄 page 264) for instruc- tions on initiating an emergency call man- ually. Once the emergency call is in progress, the indicator lamp in the SOS button will begin to flash. The message Connecting call appears in the multifunction display and the audio system is muted. When the con- nection is established, the message Call connected appears in the multifunc- tion display. All information relevant to the emergency, such as the location of the vehicle (determined by the GPS satellite location system), vehicle model, identifica- tion number and color are generated.

A voice connection between the Response Center and the occupants of the vehicle will be established automatically soon after the emergency call has been initiat- ed. The Response Center will attempt to determine more precisely the nature of the emergency provided they can speak to an occupant of the vehicle. The Tele Aid system is available if: 앫 it has been activated and is operation- al. Activation requires a subscription for monitoring services, connection and cellular air time

앫 the relevant cellular phone network

and GPS signals are available and pass the information on to the Response Center

Location of the vehicle on a map is only possible if the vehicle is able to receive signals from the GPS satellite network and pass the information on to the Response Center.

The indicator lamp 1 flashes the first time the signal transmitter button is programmed. If this button has already been programmed, the indicator lamp will only start flashing after 20 seconds.

If the indicator lamp 1 blinks rapidly for about two seconds and then turns to a constant light, continue with pro- gramming 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 buttons,

repeat the steps above starting with step 3.

Step 5: 왘 When the indicator lamp 1 flashes

rapidly, release both buttons.

Step 6: 왘 Press and hold the just-trained inte- grated signal transmitter button and observe the indicator lamp 1. If the indicator lamp 1 stays on con- stantly, programming is complete and your device should activate when the integrated signal transmitter button is pressed and released.

272

Rolling code programming To train a garage door opener (or other roll- ing code devices) with the rolling code fea- ture, 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 “train- ing” 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.

Step 9: 왘 Press “training” button on the garage

door opener motor head unit. The “training light” is activated. You have 30 seconds to initiate the following step. Step 10: 왘 Firmly press, hold for two seconds and

release the programmed integrated signal transmitter button (2, 3 or 4).

Step 11: 왘 Press, hold for two seconds and

release same button a second time to complete the training process.

Some garage door openers (or other rolling code equipped devices) may require you to perform this procedure a third time to complete the training. Step 12:

왘 Confirm the garage door operation by pressing the programmed integrated signal transmitter button (2, 3 or 4).

Step 13: 왘 To program the remaining two buttons,

repeat the steps above starting with step 3.

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 inte- grated 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 Continue to press and hold the inte- grated signal transmitter button (2, 3 or 4) while you press and re-press (“cycle”) your hand-held remote con- trol transmitter 6 every two seconds 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.

Operation of integrated remote control 왘 Switch on the ignition. 왘 Select and press the appropriate inte- grated signal transmitter button (2, 3 or 4) to activate the remote con- trolled device.

Operation The first 1000 miles (1500km)

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

276

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 engine speeds (no more than 2/3 of maximum rpm in each gear).

앫 Shift gears in a timely manner.

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 164) for the first 1000 miles (1500 km).

After 1000 miles (1500 km) you may grad- ually increase vehicle and engine speeds to the permissible maximum. All of the above instructions also apply when driving the first 1000 miles (1500 km) after the engine or the rear dif- ferential has been replaced.

Always obey applicable speed limits.

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 infla-

tion 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 by qualified technicians at the intervals specified in the Maintenance Booklet and as required by the maintenance service display. Contact an authorized Mercedes-Benz Center

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

Operation Driving instructions

Drinking and driving

Pedals

Warning!

Warning!

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 judgement.

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.

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

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 vehicle.

277

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 effect. Maintain a safe distance from vehi- cles 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 accident.

278

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.

Be very careful not to endanger other road users when you apply the brakes. Refer to the description of the Brake Assist System (BAS), (컄 page 82).

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 by quali- fied technicians 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. Install only 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 parking, so that the air stream will cool down the brakes faster.

When starting off on a slippery surface, do not allow a 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 Warranty.

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

Driving off

Parking

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.

Set the parking brake whenever park- ing or leaving the vehicle. In addition, move gear selector lever to position P (manual transmission: first or reverse gear). When parking on hills, always turn front wheel towards the curb.

Operation Driving instructions

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 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 (manual transmission: first or reverse gear).

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

wheel against curb.

앫 Turn the SmartKey to starter switch position 0 and remove the SmartKey from the starter switch.

앫 Take the SmartKey with you and lock

the vehicle when leaving.

Operation Driving instructions

Tires

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 it towed to the nearest Mercedes-Benz Center or tire dealer for repairs.

280

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

Warning!

Although the applicable federal motor vehicle safety laws consider a tire to be worn when the treadwear indicators (TWI) become visible at approximately 1/16 in (1.6 mm), we recommend 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.

Specified tire inflation pressures must be maintained. This applies particularly if the tires are subjected to high loads (e.g. high speeds, heavy loads, high ambient temper- atures).

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.

Hydroplaning

Tire traction

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.

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

Mercedes-Benz recommends M+S rated radial-ply tires with a minimum tread depth of approximately 1/6 in (4 mm) on all four wheels for the winter season to ensure normal balanced handling characteristics. On packed snow, they can reduce your stopping distance as 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 drivetrain which is not covered by the Mercedes-Benz Limited Warranty.

281

Operation Driving instructions

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 greater than the maximum 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 personal injury and possible death, for you and for others.

C 230 Kompressor (standard in U.S.A.; optional in Canada), C 320
Your vehicle is factory equipped with min. “W”-rated tires, which have a speed rating of 168 mph (270 km/h). An electronic speed limiter prevents your vehicle from exceeding a speed of 130 mph (210 km/h).

C 230 Kompressor (standard in Canada; Canada only) Your vehicle is factory equipped with “H”-rated tires, which have a speed rating of 130 mph (210 km/h). An electronic speed limiter prevents your vehicle from exceeding a speed of 130 mph (210 km/h).

For information on tire speed rating for winter tires, see “Winter driving” (컄 page 328). For additional general information on tire speed markings on tire sidewall, (컄 page 316).

282

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 gear selector lever to position N or, in case of manual transmission declutch. Try to keep the vehicle under control by corrective steering action.

For information on driving with snow chains, see “Snow chains” (컄 page 329).

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 loss of control.

Operation Driving instructions

Road salts and chemicals can adversely affect 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 after driving is resumed.

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 monox- ide (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.

Warning!

Warning!

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

The outside temperature indicator is not designed to serve as an ice-warning device and is therefore unsuitable for that purpose. Indicated temperatures just above the freez- ing point do not guarantee that the road sur- face is free of ice.

Operation Driving instructions

Standing water

Passenger compartment

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 damage is not covered by the Mercedes-Benz Limited Warranty.

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 objects.

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 transmitter

COMAND*, radio and telephone*

Warning!

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

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

1 Observe all legal requirements

Telephones and two-way radios

Catalytic converter

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 instructions regarding use of an external antenna.

Your Mercedes-Benz is equipped with monolithic-type catalytic converters, an important element in conjunction with the oxygen sensors to achieve substantial control of the pollutants in the exhaust emissions. Keep your vehicle in proper operating condition by following our recommended 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 repaired promptly. Otherwise, excessive unburned fuel may reach the catalytic converter, causing it to overheat and potentially start a fire.

Operation Driving instructions

Warning!

As with any vehicle, do not idle, park or operate this vehicle in areas where combus- tible 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.

285

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 lead to death.

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

During severe operating conditions and stop-and-go city 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 engine damage which is not covered by the Mercedes-Benz Limited Warranty.

Operation Driving instructions

Emission control

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 according to factory specifications. Any adjustments on the engine should, therefore, be carried out only by qualified Mercedes-Benz Center authorized technicians. Engine adjustments should not be altered in any way. Moreover, the specified service jobs must be carried out regularly according to Mercedes-Benz servicing requirements. For details refer to the Maintenance Booklet.

286

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 seriously burned.

앫 Steam from an overheated engine can cause serious burns and can occur just by opening the engine hood. Stay away from the engine if you see or hear steam coming from it. Turn off the engine, get out of the vehicle and do not stand near the vehicle until it has cooled down. Turn off the engine, get out of the vehi- cle and do not stand near the vehicle until the engine has cooled down.

Operation 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.

300

Warning!

Important guidelines

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

When replacing rims, 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.

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).

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 309).

Tire inspection Every time you check your tire inflation pressure, you should also inspect your
