Catalytic Converter
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 vehicl e in proper operating condition by following our recommended
maintenance instructions as outlined in your Service Booklet.


Caution!
To prevent damage to the catalytic converters, use on ly premium unleaded gasoline in this vehicle.
Any noticeable irregularities in engine operation shou ld be repaired promptly. Otherwise, excessive
unburned fuel may reach the catalytic converter causing it to overheat, which could start a fire.



Warning!
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

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


Starting
Do not depress accelerator. Brie fly turn electronic key in steering lock clockwise to the stop and
release. The starter will engage until the engine is running. If engine will not run, and the starting
procedure stops, turn electronic key completely to the left and repeat starting the engine. After
several unsuccessful attempts, have the system checked at the nearest authorized Mercedes-Benz
dealer.


Important!
Due to the installed starter nonrepeat feature, t he electronic key must be turned completely to the
left before attempting to start the engine again. The battery charge indicator lamp should go out as
soon as the engine has started. In areas where te mperatures 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.

Turning Off


Turn the electronic key in the steering lock to position 0 to stop the engine.
The electronic key can only be removed with your 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.
Inspect the tires and under the vehicle for possible da mage. If the vehicle or tires appear unsafe, have
it towed to the nearest Mercedes-Benz or tire dealer for repairs.

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


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.
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 th ereby 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 vehicle is in the shop for the required service .

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 aut horized Mercedes-Benz dealer immediately.
All checks and maintenance work on the brake system s hould 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 brak e 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
approximately1/16 in (1.5 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. As tread depth approaches 1/16 in (1.5 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 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.
Reduce vehicle speed, 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 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.

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 not snow or ice covered.
