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 1000 miles (1500 km) at moderate vehicle and engine speeds.

During this period, avoid heavy loads (full throttle driving) and high RPM.

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", "2" or "B" (for models SL 500 and SL 600) 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.

Catalytic Converter

Caution!

Warning!

Your MERCEDES-BENZ is equipped with monolithic type catalytic converters, an important element in conjunction with the oxygen sensor 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

Hot Engine

Important!

Before Starting

Engage parking brake and ensure gearshift lever is in neutral (selector lever position "P" or “N” on automatic transmissions). Turn key in steering lock to position 2. The charge indicator lamp should come on.

Cold Engine

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

Do not depress accelerator. Turn key in steering lock clock-wise 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. Note: Vehicles with automatic transmission: the key can only be removed with the selector lever in position "P". If the coolant temperature is very high (e.g. after hard driving on mountain roads), do not shut off the engine immediately, but allow it to run for 1-2 minutes at increased idle speed with selector lever in position "P" or "N".

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 Power Assistance

Warning!

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 "3", "2" or "B" (for models SL 500 and SL 600). This helps prevent overheating of the brakes and reduces brake pad wear. Do not exceed engine speed limits. Refer to Technical Data for downshift points.

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 30 mph (50 km/h) on a dry straight road. Apply parking brake lightly while pulling the release handle out 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 safe braking 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 approximately

/16in (2 mm), 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

/16in (1.5 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.

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 and 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.

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.

Parking

Warning!

To reduce the risk of personal injury as a result of vehicle movement,

turning off the engine and

before 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 periodically when traveling at length on salt-strewn roads. This can bring road salt impaired braking efficiency back to normal. A prerequisite is, however, that this is done 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 sudden 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 system will not heat or cool any quicker by setting a higher or lower temperature. The automatic climate control only operates with the engine running. Higher engine rpm results in higher coolant compressor rpm, thereby increasing cooling capacity.

The automatic climate control removes considerable moisture from the air during operation in the cooling mode. It is normal for water to drip on the ground through ducts in the underbody. Outside air is drawn in through a filter. Dust particles (up to a certain size) and pollen are filtered out.

Important!

This vehicle is equipped with an air conditioner system that uses HFC-134a (ozone-friendly hydro-fluorocarbon) as a refrigerant. Repairs should always be performed by a qualified technician, and refrigerant should be collected in a recovery system for recycling.

Turn master key to position 2, turn back to position 1 and remove.

Separate Locking and Unlocking of Trunk

If the trunk is to remain locked (e.g. when leaving the car at a parking garage or workshop), lock the trunk separately. Turn master key to position 4 and remove in this position. Leave only the valet key with the vehicle.

The trunk (and fuel filler flap) remain locked - even if the central locking system was engaged from outside and a door is opened from inside of car (theft deterrence).

To unlock turn master key to position 2, then back to position 1 and remove.

If the trunk is unlocked, the doors and fuel filler flap will also be unlocked. After closing the trunk, the central locking system must again be engaged to relock the doors and fuel filler flap.

Note: If the fuel filler flap cannot be opened, refer to Manual Release of Fuel Filler Flap in Index.

Closing Windows from Outside

Turn key in door lock or trunk lock to the locking position 3 and hold. The windows begin to close after approx. 1 second.

Note: If the closing procedure is interrupted, it can only be continued by first turning the key to the unlocked position (2) and then again to the locking position (3).

Warning!

Never close the windows if there is the possibility of anyone being harmed by the raising window.

In case the closing procedure causes potential danger, the closing procedure can be immediately interrupted by turning the key back to the vertical position. However, the windows can only be lowered using the power window buttons inside the car.

Emergency Unlocking in Case of Accident

The doors unlock automatically a short time after the roll bar is deployed in an accident (this is intended to aid rescue and exit). However, the key in the steering lock must be in steering lock positions 1, 2 or returned to position 0, but not removed.
