Drive Sensibly - Save Fuel
Fuel consumption to a great extent
depends on driving habits and operat
ing conditions.
To save fuel you should:
• keep tires at the recommended
inflation pressures
• remove unnecessary loads
• remove ski racks or roof-mounted
luggage racks when not in use
• allow engine to warm up under low
load use
• avoid frequent acceleration and
deceleration
• have all maintenance work
performed at regular intervals by
an authorized MERCEDES-BENZ
dealer.
Fuel consumption is also increased
by driving in cold weather in stop-
and-go traffic on short trips and in hilly
country.

The First 1500 km (1000 Miles)
The more cautiously you treat your
vehicle during the break-in period the
more satisfied you will be with its per
formance 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 RPMs
(no more than 2/3 of maximum permis
sible speed in each gear).
Downshift at proper engine speed!
On vehicles with automatic transmis
sion avoid accelerating by kick-down.
It is not recommended to brake the
vehicle by manually shifting to a lower
gear. We recommend to select posi
tions “3” or “2” only at moderate
speeds (for hill driving).
After 1500 km (1000 miles) speeds
may gradually be increased to the
permissible maximum.

Catalytic Con erter Cautions
Your MERCEDES-BENZ is equipped
with monolithic catalytic converters an
important element in conjunction with
the 0 2-sensor to achieve substantial
control of the pollutants in the exhaust
emissions. Keep your vehicle in proper
operating condition by following our
recommended maintenance instruc
tions as outlined in your maintenance
booklet.
Caution!
To prevent damage to the catalytic
converters only use premium
unleaded gasoline in this vehicle.
Should any noticeable irregularities in
the engine operation occur excessive
unburned fuel may reach the conver
ter causing it to overheat.
Warning!
As with any ehicle, do not idle,
park, or operate this ehicle in
areas where combustible materials
such as grass, hay or lea es can
come in contact with a hot exhaust
system, as these materials could be
ignited.

Starting and Turning off the Engine
Engage parking brake before starting
the engine.
Move gearshift lever to neutral (selec
tor lever positions “P” or “N” on auto
matic transmissions).
Turn key to steering lock position 2.
The charge indicator lamp should
come on.
Cold Engine
Turn key in steering lock clockwise to
the stop. Do not depress accelerator.
Release key only when the engine is
firing regularly.
At ambient temperatures below
-18° C (0° F) depress accelerator
three times prior to starting.
Hot Engine
Turn key in steering lock clockwise to
the stop. Do not depress accelerator.
If the engine has not fired after
approx. 4 seconds depress accel
erator and continue cranking until the
engine is firing regulary. 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 and remove only when the
vehicle has stopped.
If the coolant temperature is very high
(e.g. after hard driving on mountain
roads) do not shut off the engine
immediately allow it to run for
1-2 minutes at increased idle speed.
Important!
Due to the installed starter non-repeat
unit the key must be returned to steer
ing lock position 0 before a new start
ing attempt is made.
Observe the oil pressure gauge
immediately after starting the engine.
In a very cold engine the oil pressure
will only rise slowly some time after the
engine has started. Do not speed up
the engine before pressure is regis
tered on the pressure gauge.
The charge indicator lamp should go
out as soon as the engine has started.
Should too much fuel have entered the
engine due to several unsuccessful
starting attempts and the engine will no
longer fire depress the accelerator
while starting. This should make
the mixture combustible again.
Back off the accelerator only when
the engine is firing regularly.
In areas where temperatures fre
quently drop below -25°C (-13°F)
we recommend that a block heater be
installed. Any authorized MERCEDES-
BENZ dealer will advise you on this
subject.

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.
Brakes
Warning!
When dri ing down long and steep
grades, relie e the brakes by shift
ing into a lower gear (selector
le er position “3” or “2” in the case
of automatic transmissions). This
helps pre ent o erheating of the
brakes. Otherwise the brakes will
o erheat and this may result in a
brake failure.
After hard braking it is advisable to
drive on for some time so the air
stream will cool down the brakes
faster.
Warning!
After dri ing in hea y rain for some
time without applying the brakes or
through water deep enough to wet
Driving Hints 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 ehicles in front.
The condition of the parking brake
system is checked each time the car is
in the shop for maintenance.
Between maintenance checks it is a
good practice to apply the parking
brake once or twice while driving at
approximately 50 km/h (30 mph) on a
dry straight road. Apply brake lightly
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
pre ious paragraph only when the
road is clear of other traffic.
Caution!
Resting your foot on the brake pedal
will cause excessive and premature
wear of the brake pads.
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 instru
ment cluster stays on the brake fluid
level in the reservoir is too low.
Brake pad wear or a leak in the sys
tem may be the reason for low brake
fluid in the reservoir.
Have the brake system inspected
at an authorized MERCEDES-BENZ
dealer without delay.
Use only brake pads and brake fluid
recommended by MERCEDES-BENZ.
If other than recommended brake
pads are installed the braking proper
ties of the vehicle can be affected to
an extent that the safety is substan
tially impaired.

Tires
Tread wear indicators (TWI) are
required by law. These indicators are
located in six places on the tread cir
cumference and become visible at a
depth of approx. 2 mm (1/i6 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
(Vs in) of tread, the adhesion proper
ties on a wet road fall off sharply.
Depending upon the weather and/
or road surface (conditions), the
traction aries widely.
Specified tire pressure must be main
tained. This applies particularly if the
tires are subjected to high loads
(e.g. high speeds heavy loads high
ambient temperatures).
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 friction
The safe speed on a wet 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, dri e, 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.

Warning!
To reduce the risk of personal
injury as a result of ehicle mo e
ment, before lea ing the ehicle
always:
1. Keep foot on brake pedal.
2. Pull up parking brake le er.
3. Slowly release brake pedal.
4. Engage first or re erse gear
(selector le er position “P” in
the case of automatic transmis
sions).
5. Turn front wheels towards the
road curb.
6. Turn the key to steering lock
position 0 and remo e.
Clutch
Caution!
Resting your foot on the clutch pedal
will cause excessive and premature
wear of the clutch disc.
Parking
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 an au
tomatic transmission move selector
lever to position “N”. Try to keep the
vehicle under control by corrective
steering action.
Vehicles without ABS:
Provided the traffic conditions will
allow only brake in a way that the
wheels are locked for no more than
fractions of a second as otherwise the
steerability of the vehicle is lost.
Winter Dri ing Hints 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 saltstrewn roads at
length. This can bring road salt impair
ed braking efficiency back to normal.
A prereguisite 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.
