13
Catalytic Converter
Caution!
Warning!
Your Mercedes-Benz is equipped with
monolithic type catalytic converters, an
important element in conjunction with
the O2 - 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.
14
Starting and Turning Off the Engine
Hot Engine
Important!
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.
Cold Engine
Do not depress accelerator. Turn key
in steering lock clockwise to the stop.
Release key only when the engine is
firing regularly.
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".
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 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!
Warning!
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". 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.
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
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
16
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
degraded 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 approximately1/16in
(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. With less than1/16in
(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, or tire blowout
17
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!
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 com-pared 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.
If ice has formed on the road, tire
traction will be substantially
reduced. Under such weather
conditions, drive, steer and brake
with extreme caution.
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.
18
Winter Driving Instructions
The most important rule for slippery or
icy roads is to drive sensibly and to
avoid abrupt acceleration, braking and
steering maneuvers. 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 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
