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.

Starting and Turning Off the Engine

Before Starting

Engage parking brake and move the selector lever to position "P" or "N".

Cold Engine

Turn key to steering lock position 2. Charge indicator and pre-glow indicator lamp should come on. The preglow process starts. When the preglow indicator lamp goes out, the engine is ready for starting.

Ambient temperatures above + 14°F (-10°C):

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

Ambient temperatures below +14°F(-10°C):

Depress accelerator party. Turn key in steering lock clockwise to the stop. Release key only when the engine is firing regularly and back off accelerator slowly.

Do not interrupt the starting process. If the engine is very cold, it is possible that it will fail to start on subsequent attempts.

At ambient temperatures below 0°F (-18°C), depress accelerator three times prior to starting.

Hot Engine

Turn key in steering lock clockwise to the stop and start engine immediately without depressing the accelerator.

Turning off

Turn the key in the steering lock to position 0 only when the vehicle has stopped moving. The key can only be removed with the selector lever in position "P". Should the engine continue to operate with the key in steering lock position 0, refer to Engine, Turning Off Manually in Index.

If the coolant temperature is very high (e.g. after hard driving on mountain roads), do not shut off the engine immediately, allow it to run for 1 - 2 minutes at increased idle speed with selector lever in position "P" or "N".

Important!

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

If the preglow indicator lamp fails to light up, or lights up while driving, the preglow system is defective and should be repaired at your authorized Mercedes-Benz dealer at the earliest possible date.

The engine is equipped with a block heater to provide reliable starting at temperatures below 0° F (-18°C). Refer to Winter Driving in Index.

Driving Instructions

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.

Brakes

Caution!

When driving down long and steep grades, relieve the load on the brakes by shifting into a lower gear (selector lever position "4" , "3" , "2". This helps prevent overheating of the brakes and reduces brake pad wear. Do not exceed engine speed limits (see Index).

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.

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.

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

Between maintenance checks, it is a good practice to apply the parking brake once or twice while driving at approximately 50 km/h (30 mph) on a dry straight road. Apply parking brake lightly until a slight drag on the wheels is felt. Keep applying the brake for about 10 seconds while pulling the release handle out before releasing the parking brake completely. This practice will keep the parking brake at maximum efficiency.

Warning!

The stop lamps will not come on when applying the parking brake only. Perform the procedure in the previous paragraph only when the road is clear of other traffic.

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.

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

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.

Install only brake pads and brake fluid recommended by MERCEDES-BENZ.

Warning!

If other than recommended brake pads are installed, the braking properties of the vehicle can be affected to an extent that the safety is substantially impaired.

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!

Aquaplaning

Warning!

Do not allow your tires to wear down too far. With less than1/8in (3 mm) 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.

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!

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.

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

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.

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 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 wet or dry.

Parking

Warning!

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

1. Keep right foot on brake pedal.

2. Firmly depress parking brake pedal.

3. Move the selector lever to position "P".

4. Slowly release brake pedal.

5. Turn front wheels towards the road curb.

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

Important!

It is advisable to set the parking brake whenever parking or leaving the vehicle. In addition, move selector lever to 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 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.
