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. There-
fore, 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 (no more than
*/a
of
maximum permissible speed in
each gear as indicated on the
speedometer).
Downshift at proper engine speed!
On vehicles with automatic trans-
mission avoid accelerating by
kick-down. 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 gradually be
increased to the permissible
maximum.

See Index
13

Catalytic Converter
Your Mercedes-Benz is equipped
with monolithic 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.
Caution!
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 converter causing it to
overheat.
Warning!
As with any vehicle, do not
idle, park, or operate this vehicle in areas where combus-
tible 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
Yurning
Off the
Engine
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 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 de-
pressed 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 trans-
mission: 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 in-
creased idle speed with selector
lever in neutral or position “P”.
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 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 -13°F
(-25”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 a lower
gear (selector lever position “3”
or “2” in the case of automatic
transmission). 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 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.
Raise parking brake lever lightly
while holding the release button in
until a slight drag on the wheels is
felt. Keep applying brake for about
10 seconds while holding the
release button in 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 effective-
ness. 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 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
l/16
in (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
'/8
in (3 mm) of tread, the
adhesion properties on a wet
road fall off sharply.
Depending upon the weather
and/or road surface (conditions), the traction varies
widely.
Specified tire pressure must be
maintained. This applies particularly if the tires are subjected to
high loads (e. g. high speeds,
heavy loads, high ambient
temperatures).
Do
not drive withaflat 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
ex-
17

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.

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 foot on brake pedal.
2. Pull up parking brake lever.
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
apply the parking brake.
Clutch
Caution!
Resting your foot on the clutch
pedal will cause excessive and
premature wear of the clutch disc.

Winter Driving Instructions
The most important rule for
slippery or icy roads is to drive
sensibly and to avoid abrupt ac-
celeration, 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
an automatic transmission move
selector lever to position “N”. Try
to keep the vehicle under control
by corrective steering action.
Road salts and chemicals can ad-
versely affect braking efficiency.
Increased pedal force may be-
come 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 safe-
ty 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 ve-
,
hicle
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.
