Drive Sensibly - Save Fuel
Fuel consumption depends to a
great extent on driving habits and
operating conditions.
n order to save fuel you should:
• ensure that tire pressures are
correct
• not carry unnecessary loads
• remove ski racks or roof-m ount
ed luggage racks when not in
use
• not warm up your engine at idle
and with the vehicle at standstill
• avoid frequent acceleration and
deceleration
• shift gears on time, do not ex
ceed % of the individual gears'
max. speed
• have all the maintenance jobs
specified by us carried out at
regular intervals by an au
thorized MERCEDES-BENZ
dealer.
Driving in low temperature weather,
in stop-and-go city traffic and on
short hops, and in hilly country as
well, increases fuel consumption.

The First 1500 km/1000 Miles
The more cautiously you treat your
engine during the break-in period,
the more satisfied you will be with
its performance 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 % of maximum
permissible speed in each gear).
Down shift at proper engine speed!
On vehicles with automatic trans
mission avoid accelerating by kick-
down. t is not recommended to
brake the vehicle by manually shift
ing to a lower gear. We recommend
to select positions “3” or “2” only at
moderate speeds (for hill driving).
After 1500 km/1000 miles, speeds
may gradually be increased to the
permissible maximum.

Starting and Turning off the Engine
Engage parking brake before start
ing the engine.
Move gearshift lever to neutral
(selector lever positions “P” or “ N”
on automatic transmissions).
Cold Engine
Turn key in steering lock to posi
tion 2. Charge indicator and pre
glow indicator lamp must come on.
The preglow process starts. When
the preglow indicator goes out, the
engine is ready for starting.
Ambient Temperature
exceeding 0° Cl +32° F:
Turn key in steering lock clockwise
to the stop. Do not depress accel
erator. Release key only when the
engine is firing regularly.
Ambient Temperature
below 0°C/ +32° F:
Depress accelerator and clutch ped
al (if applicable) to the floor. Turn
key in steering lock clockwise to the
stop. Release key only when the en
gine is firing regularly and back off
accelerator slowly.
Do not interrupt the starting proc
ess. f the engine is very cold it is
possible that it will fail to start on
subsequent attempts.
Hot Engine
Turn key in steering lock clockwise
to the stop and start engine immedi
ately without depressing the accel
erator. Release the key as soon as
the engine is firing regularly.
Turning off
Turn key in steering lock to posi
tion 0 and remove only when the
vehicle has stopped.
Should the engine continue to oper
ate with the key in steering lock
position 0, refer to page 66.
With very high coolant tempera
tures (e.g. after driving on mountain
passes), do not shut down the en
gine immediately but allow it to run
at slightly increased idle speed for
approximately 1-2 minutes.
Notes:
Due to the installed starter non
repeat unit, the key in the steering
lock must be returned to 0 position
before making a new starting at
tempt.
Observe the oil pressure gauge im
mediately after starting. n 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 must go
out as soon as the engine has
started.
f the preglow indicator fails to light
up, the preglow system is defective
and should be repaired at an au
thorized MERCEDES-BENZ dealer
at the earliest possible date.
n areas where temperatures fre
quently drop below -18° C/0° F, we
recommend that a block heater is
installed. Every MERCEDES-BENZ
dealer will advise you on this sub
ject.

Hints for Driving
Power assistance
When the engine is not running,
both the service brake and the
steering are without power assistance.
Under these circumstances, a much
greater effort is necessary to steer
or stop the vehicle.
Tires
Do not allow your tires to wear
down too far. With less than 3 mm/
% in of tread, the antiskid proper
ties on a wet road are sharply re
duced.
Depending upon the weather and/or
road pavement, the 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).
Aquaplaning
Depending on the depth of the
water layer on the road, aquaplan
ing may occur, even at low speeds.
Avoid track grooves in the road and
apply brakes cautiously in the rain.
Tire friction
A given speed at which a vehicle
driven on dry roads can still be fully
controlled must be reduced when
the same vehicle is to be driven
safely on a wet or icy road.
You should pay particular attention
to the condition of the road as soon
as the prevailing temperatures fall
close to the freezing point.
f ice has formed on the road, tire
traction will be substantially re
duced. Under such weather condi
tions, drive, steer and brake particu
larly carefully.
We recommend M + S radial-ply tires
for the cold season. On packed
snow, they can reduce your stop
ping distance as compared with sum
mer tires. Stopping distance, how
ever, is nevertheless considerably
greater than when the road is wet or
dry.
rakes
When driving down long and steep
declines, relieve the brakes by shift
ing into a lower speed (selector
lever position “3” or “2" in the case
of automatic transmissions). This
prevents overheating of the brakes
and reduces brake pad wear.
After hard braking it is advisable to
drive on for some time so the air
stream will cool down the brakes
faster.
When driving in heavy rain for some
time without applying the brakes,
the first braking action may be
somewhat reduced and increased
pedal pressure may be necessary.
For this reason, stay further away
from vehicle 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 road. Apply brake lightly until a
slight drag on the wheels is felt.
Keep applying brakes for about
10 seconds while holding release
button in before releasing 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. Apply parking brake only
when road behind vehicle is clear of
traffic.
All checks and maintenance work
on the brake system should be car
ried out by a MERCEDES-BENZ
dealer.
f the parking brake is released and
the brake warning lamp in the in
strument 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.
nstall only brake pads recom
mended by us.
f other than recommended brake
pads are installed, the braking pro
perties of the vehicle can be af
fected to an extent that the safety is
substantially impaired.
Driving Hints During the Winter
Season
The most important rule for slippery
or icy roads is to drive sensibly and
to avoid abrupt acceleration, brak
ing 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
means of corrective steering action.
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.
Road salts and chemicals can ad
versely affect braking efficiency.
ncreased pedal force may become
necessary to produce the normal
brake effect. We therefore recom
mend depressing the brake pedal
repeatedly when traveling on salt-
strewn roads at length. This can
bring road salt impaired braking ef
ficiency back to normal. A prere
quisite is, however, that this is poss
ible without endangering other driv
ers on the road.
f 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 adhering to the safe
ty requirements.

MERCEDES-BENZ Maintenance System
A maintenance booklet is delivered
with your car listing all the mainte
nance jobs that must be carried out
after the following mileages:
Routine Maintenance
nspection at
1300-1600 km/800-1000 miles
Lubrication Service every
8000 km/5000 miles
Maintenance Service every
24 000 km/15 000 miles
Additional Work every
48 000 km/30 000 miles
n the case of low mileage opera
tion, the Maintenance Service must
be carried out at least once every
2 years.
Engine Oil and Filter Change
Required every 8000 km/5000 miles,
or at least once a year when using
year-round multigrade oil; other
wise at least twice a year (spring
and fall).
Under severe operating conditions
or if diesel fuels with high sulphur
content (in excess of 0.5% by
weight) are used, the oil and filter
should be changed every 4000 km/
2500 miles.
Severe Operating Conditions
n the case of severe operating con
ditions or heavy use mainly in city
traffic or over short distances, fre
quent mountain driving, poor roads,
dusty and muddy conditions, trailer
operation, hard and sporty driving
etc., it may be necessary to carry
out maintenance work at shorter
than normal intervals, as follows:
Engine: Oil change with filter
change every 4000 km/2500 miles
Automatic transmission: Fluid
change without filter change every
24 000 km/15 000 miles
Tires: nspect
Air cleaner: Clean or replace ele
ment
Special Maintenance Measures
rake fluid should be replaced an
nually, preferably in the spring.
t is recommended to use only
brake fluid approved by
MERCEDES-BENZ.
The coolant should be checked for
sufficient protection before the start
of and during the cold season.
Have the coolant (water/anticorro
sion/antifreeze mixture) replaced at
least every three years (see “ Fuels,
Coolants, Lubricants, etc.”).
Maintenance Vouchers
Your authorized MERCEDES-BENZ
dealer will certify in the mainte
nance booklet that all lubrication
and maintenance services have
been carried out at the correct in
tervals.
Stickers to remind you when the
next lubrication service or mainte
nance service is due, or when the
brake fluid must be changed, are
provided in the middle of the
maintenance booklet.
Sticker attaching points
n the frame of the driver’s door:
