The First 1000 Miles (1500 km)

The more cautiously you treat your vehicle during the break-in period, the more satisfied you will be with its performance later on. Therefore, drive your vehicle during the first 1500 km (1000 miles) at moderate vehicle and engine-speeds. During this period, avoid heavy loads (full throttle driving) and high RPM (no more than 2/3 of maximum permissible speed in each gear as indicated on the speedometer). Avoid accelerating by kickdown. It is not recommended to brake the vehicle by manually shifting to a lower gear. We recommend to select positions "3" or "2"only at moderate speeds (for hill driving). After 1000 miles (1500 km) speeds may be gradually increased to the permissible maximum

Maintenance

We strongly recommend that you have your vehicle serviced by your authorized Mercedes-Benz dealer, in accordance with the Maintenance Booklet.

Failure to have the vehicle maintained in accordance with the Maintenance Booklet may result in vehicle damage not covered by the Mercedes-Benz Limited Warranty.

Radio Transmitters

Warning!

Never operate radio transmitters equipped with a built-in or attached antenna (i.e. without the telephone connected to an external antenna) from inside the vehicle while the engine is running. Doing so could lead to a malfunction of the vehicle's electronic system, possibly resulting in an accident and personal injury.

Radio transmitters, such as a portable telephone or a citicens band unit should only be used inside the passenger compartment, if they are connected to a Mercedes-Benz approved antenna that is installed on the outside of the vehicle.

Catalytic Converter

Caution!

Warning!

Your MERCEDES-BENZ is equipped with monolithic type catalytic converters, an important element in conjunction with the O2sensor 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 converters, 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, which could start a fire.

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

Starting and Turning Off the Engine

Important!

Turning Off

Before Starting

Ensure that parking brake is engaged and that selector lever is in position "P" or "N". Turn key in steering lock to position 2. The charge indicator lamp should come on.

Starting

Do not depress accelerator. Turn key in steering lock clockwise to the stop. Release key only when the engine is firing regularly

Due to the installed starter non-repeat feature, the key must be turned completely to the left before attempting to start the engine again.

Observe the oil pressure gauge immediately after starting the engine. In a very cold engine the oil pressure will rise slowly after the engine has started. Do not speed up the engine before pressure is registered on the pressure gauge. If you do not see the gauge register oil pressure, stop the engine and have it checked.

The charge indicator lamp should go out as soon as the engine has started.

In areas where temperatures frequently drop below -4°F (-20°C) we recommend that an engine block heater be installed. Your authorized Mercedes-Benz dealer will advise you on this subject.

Turn the key in the steering lock to position 0 to stop the engine.

The key can only be removed with the foot off the brake pedal and the selector lever in position "P".

Driving Instructions

Warning!

If you feel a sudden significant vibration or ride disturbance, or you suspect that possible damage to your vehicle has occurred, you should turn on the hazard flashers, carefully slow down, and drive with caution to an area which is a safe distance from the roadway.

Brakes

Warning!

After driving in heavy rain for some time without applying the brakes or through water deep enough to wet brake components, the first braking action may be somewhat reduced and increased pedal pressure may be necessary. Be sure to maintain a safe distance from vehicles in front.

If the parking brake is released and the brake warning lamp in the instrument cluster stays on, the brake fluid level in the reservoir is too low.

Brake pad wear or a leak in the system may be the reason for low brake fluid in the reservoir.

Have the brake system inspected at an authorized Mercedes-Benz dealer immediately.

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

Power Assistance

When the engine is not running, the brake and steering systems are without power assistance. Under these circumstances, a much greater effort is necessary to stop or steer the vehicle.

Resting your foot on the brake pedal will cause excessive and premature wear of the brake pads.

It can also result in the brakes overheating thereby significantly reducing their effectiveness. It may not be possible to stop the car in sufficient time to avoid an accident.

The condition of the parking brake system is checked each time the car is in the shop for the required maintenance.

All checks and maintenance work on the brake system should be carried out by an authorized MERCEDES-BENZ dealer.

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.

Caution!

When driving down long and steep grades, relieve the load on the brakes by shifting into a lower gear. This helps prevent overheating of the brakes and reduces brake pad wear.

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

Warning!

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

Tires

Tread wear indicators (TWI) are required by law. These indicators are located in six places on the tread circumference and become visible at a depth of approx. 2 mm (1/16 in), at which point the tire is considered worn and should be replaced.

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

Warning!

Do not allow your tires to wear down too far. With less than 1.5 mm (1/16 in) of tread, the adhesion properties on a wet road are sharply reduced.

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

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 car. 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, or tire blowout.

Aquaplaning

Depending on the depth of the water layer on the road, aquaplaning may occur, even at low speeds and with new tires. Avoid track grooves in the road arid apply brakes cautiously in the rain.

Tire Traction

Despite the tire rating, local speed limits

before

vehicle.

Tire Speed Rating

Parking

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 as soon as the prevailing temperatures fall 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.

We recommend M+S rated radial-ply tires for the winter season for all four wheels to insure normal balanced handling characteristics.

On packed snow, they can reduce your stopping distance as compared with summer tires. Stopping distance, however, is still considerably greater than when the road is not snow or ice covered.

Your vehicle is factory equipped with "H" -rated tires, which have a European speed rating of 130 mph (210 km/h). An electronic speed limiter prevents your vehicle from exceeding the speed rating.

should be obeyed. Use prudent driving speeds appropriate to prevailing conditions.

Warning!

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

Exceeding the maximum speed for which tires are rated can lead to sudden tire failure causing loss of vehicle control and resulting in personal injury and possible death.

Warning!

To reduce the risk of personal injury as a result of vehicle movement, turning off the engine and leaving the vehicle always:

1. Keep foot on brake pedal.

2. Firmly depress parking brake pedal.

3. Engage first or reverse gear (selector lever position "P" in the case of automatic transmissions).

4. Slowly release brake pedal.

5. Turn front wheels towards the road curb,

6. Turn the key to steering lock position 0 and remove.

7. Take your key and lock vehicle when leaving.

Important!

It is advisable to set the parking brake whenever parking or leaving the In addition, engage first or reverse gear (selector lever position "P"). When parking on hills, always set the parking brake.

Winter Driving Instructions

The most important rule for slippery or icy roads is to drive sensibly and to avoid abrupt acceleration, braking and steering action. Do not use the cruise control system under such conditions.

When the vehicle is in danger of skidding, declutch, or in case of automatic transmission move selector lever to position "N". Try to keep the vehicle under control by corrective steering action.

Road salts and chemicals can adversely affect braking efficiency. Increased pedal force may become necessary to produce the normal brake effect. We therefore recommend depressing the brake pedal repeatedly when traveling on salt-strewn roads at length. This can bring road salt impaired braking efficiency back to normal. A prerequisite is, however, that this is possible without endangering other drivers on the road.

If the vehicle is parked after being driven on salt treated roads, the braking efficiency should be tested as soon as possible after driving is resumed while observing the safety rules in the previous paragraph.

Warning!

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

To assure sufficient fresh air ventilation, open a window slightly on the side of the car that is out of the wind.

Deep Water

Caution!

Do not drive through flooded areas or water of unknown depth.

If you must drive through deep water, drive slowly to prevent water from entering the engine compartment or being ingested by the air intake, possibly causing damage to electrical components or wiring, to engine or transmission that is not covered by the Mercedes-Benz Limited Warranty.

Passenger Compartment

Warning!

Always fasten items being carried as securely as possible.

In an accident, during hard braking or suden 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.

Operation

Automatic Climate Control

The system is always at operational readiness, except when manually switched off.

The automatic climate control only operates with the engine running

Radio Frequency and Infrared Remote Control

The master key has an integrated radio frequency and infrared remote control.

Due to the extended operational range of the remote control, it could be possible to unintentionally lock or unlock the vehicle by pressing the transmit button.

The vehicle doors, trunk and fuel filler flap can be centrally locked and unlocked.

Closing the windows and sliding/popup roof can only be done with the infrared portion of the remote control. Aim transmitter eye (4) at a receiver (5 or 6) and press transmit button.

With vehicle centrally locked, the trunk can also be opened by using the remote control.

If the key is inserted in steering lock, the vehicle cannot be locked or unlocked with the remote control.
