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.

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.

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.

Starting and Turning off the Engine

Cold Engine

Important!

Before Starting

Important!

The engine can only be started, if the vehicle was unlocked from the outside.

Before Starting

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

Note:

If transmit button of the remote control is inadvertently pressed again prior to starting the engine, the start lock-out is activated. In this case press transmit button again to deactivate the start lockout.

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

Hot Engine

Do not depress accelerator. Turn key in steering lock clockwise to the stop. If the engine has not fired after approx. 4 seconds, depress accelerator and continue cranking until the engine is firing regularly. Release key and back off accelerator.

At very high coolant temperatures the engine starting time can be shortened if the accelerator is depressed slowly at the beginning of the starting process.

Turning Off

Turn the key in the steering lock to position 0 to stop the engine. The key can only be removed with the selector lever in position "P".

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 battery 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.

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.

Caution!

When driving down long and steep grades, relieve the load on the brakes by shifting into "3", "2" or "1" (model S 320: "3" or "2"). This helps prevent overheating of the brakes and reduces brake pad wear.

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 3 mm (1/8 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.

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, 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

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 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.

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.

Despite the tire rating, local speed limits 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, before 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.

Important!

It is advisable to set the parking brake whenever parking or leaving the vehicle. 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.

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.

If the green and red indicator lamps simultaneously flash for approx. 30 seconds, or the vehicle cannot be locked or unlocked by pressing the transmit button, then it may be necessary to change the batteries in the transmitter (if ok, battery indicator lamp in transmitter will light briefly when transmitting) or to synchronize the system, see Remote Control, Infrared in Index.

Closing Windows and Sliding/ Pop-Up Roof from Outside

Continue to press transmit button (1) after locking car. Distance to receiver max. 10 ft. (3 m).

The windows and sliding/pop-up roof begin to close after approx, 2 seconds.

Warning!

Never close the windows or sliding/ pop-up roof if there is the possibility of anyone being harmed by the closing procedure.

In case the closing procedure causes potential danger, the closing procedure can be immediately reversed by releasing and pressing the remote control button again until the green indicator lamp at the receiver blinks. The sliding/pop-up roof and windows will open again. The sliding/pop-up roof will only open if it was not fully closed.

Note:

If the side windows and sliding/ popup roof cannot be closed automatically by using the key or by pressing the transmit button of the infrared remote control (e.g. after a battery change), press side of power window switch in center console until the window is completely closed and hold for additional 2 seconds. Repeat procedure for each window.

The automatic closing procedure of the windows and sliding/pop-up roof should now be restored.
