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. It is not recommended to brake the vehicle by manually shift ing to a lower gear. We recommend to select positions 3 or 2only 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 autom atic 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 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. If 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 im medi 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 imm ediately 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. In a very cold engine the oil pressure will only rise slowly, some tim e 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.
If 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.
In 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 circum stances, 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 am bient 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 tem peratures fall close to the freezing point.
If 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.
Brakes
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 tim e 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.
If 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. Install only brake pads recom
mended by us. If 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.
Increased 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 norm al. A prere quisite is, however, that this is poss
ible without endangering other driv ers 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 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
Inspection 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
In 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
In 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
Autom atic transmission: Fluid change without filter change every 24 000 km/15 000 miles
Tires: Inspect Air cleaner: Clean or replace ele
ment
Special Maintenance Measures Brake fluid should be replaced an
nually, preferably in the spring. It 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
In the frame of the drivers door: Lubrication service and mainte nance service
In the engine compartment: Brake fluid change.

Air Distribution
Air conditioned, warmed, or fresh air may be direct ed to the foot area, the windshield, and the side out lets (8). The center outlets (6) are for non-heated air only.
The air volume through the center outlets (6) and side outlets (8) may be changed with levers (7) and (9) respectively. Pushing the lever up opens the air out lets completely.
Temperature Selection
Use the temperature selector wheel to set the
I desired temperature. The selected temperature is
reached as quickly as possible and maintained. Use a basic setting of 22. Refine your setting only in small steps to avoid large temperature fluctuations.
MIN (notched-in) = maxim um cooling or fresh air dependent on push button selection of the air condi tioning mode control.
MAX (notched-in) = maximum heating.

Master Key - square head - fits all locks on the car.
Supplem entary Key - rounded
head - fits only the door locks and the steering lock. This key is intend ed to be used whenever the car is
left with an attendant. Be sure to
lock glove compartment and trunk
with the master key.
T
FIat Key
The flat key fits all vehicle locks. We recommend that you carry the flat key with you and keep it in a safe place so that it is always handy, if needed (e.g. in your wallet). Never leave the flat key in the vehicle.
Obtaining Replacement Keys
You are given 4 keys with your vehi cle. Replacement keys can be ob tained only via an authorized
MERCEDES-BENZ dealer. For sec urity reasons, obtaining replace ment keys requires considerable
time.
24
Opening the Doors From outside: pull handle out
wards (1).
From inside: pull handle in door
trim panel (4).
Locking and Unlocking of Doors From the outside: turn key.
From the inside: actuate button. 2 Unlocking 3 Locking
When the rear door buttons are pushed down, the rear doors can not be opened from the outside or the inside. They can only be opened after pulling buttons up.
One cannot lock:
the drivers door if it is open
any door if the door lock has not engaged fully. In this case open the door and close it again.
25
Central Locking System
The entire vehicle may be locked or
unlocked with the central locking
system:
Using the master key, supplementary key, or by push ing down or pulling up the in terior door lock buttons at the front doors.
From the trunk using the master key only.
The central locking system allows you to lock or unlock all doors, trunk lid and fuel filler flap sim ul taneously.
Doors When you lock the car, all door lock
buttons should move down. If any one stays up, the respective door was not properly closed. You should then unlock the car, open and re-close this door, and lock the car again.
Note:
The central locking system can be
engaged from the driver-side door lock button, provided the door is completely closed. It can also be engaged from the passenger-side if the key is removed, or engaged
in the steering lock w ithout being
turned (key in position 0). Trunk
To unlock the trunk with the central
locking system, turn the master key in the trunk lock completely to the left and let it return to the normal
position. Push in trunk lock button and open the trunk. To lock the trunk, turn the master key com
pletely to the right and let it return to the normal position.
The tru nk can remain locked while the central locking system is un
locked (e. g. while driving or when leaving the car in a situation where it must be driven using the sup plementary key but you wish the
trunk to remain locked at parking
lots, workshops, etc.). Turn the
master key completely to the right and pull it out in that position. Now the trunk can only be unlocked with the master key by turninq it back to the left.
Im portant! Contrary to p rior model year vehi
cles, if the trunk is unlocked with the central locking system engaged, the doors and fuel filler flap will also be unlocked. After closing the trunk, the central locking system
must again be engaged using the key!
Note: If the fuel filler flap cannot be
opened, refer to Unlocking of Fuel Filler Flap" (page 75).
Anti-Theft Alarm System The anti-theft alarm can be armed
or disarmed with the master key (identified by red dot) by locking or unlocking either front door or the trunk.
Operation Once the alarm system has been
armed, the vehicle lamps will flash and the horn will sound interm it tently when an unauthorized person tries to:
open a door
open the trunk
remove the radio
switch on or bridge the steering lock
step on the brake pedal
raise the vehicle, i.e. towing away.
The alarm will last approximately
150 seconds in the form of blinking exterior lamps. At the same time an additional horn w ill sound intermit tently for 60 seconds, and repeat for another 60 seconds after a 30 sec ond pause.
The alarm will stay on even if the arming elem ent (a door, for exam ple) is immediately closed.
To avoid setting off the alarm unin tentionally, do not arm the alarm system in the follow ing situations; e.g.: Auto ferry, auto train, when hitching/unhitching a trailer, or heavy loading/unloading. For this purpose use the supplem entary key and not the master key for locking the vehicle.
Special function To activate the anti-theft alarm from
the trunk, turn the master key in the trunk lock completely to the right and pull it out in this position.
If you want the alarm system to be armed at the trunk only, turn the
master key in the trunk lock com pletely to the right and pull it out in that position. Then disarm the rest of the vehicle by unlocking either fron t door with the master key. You can now lock or unlock the doors and filler flap, as well as start the engine, in the usual manner using the supplementary key.
Do not give the master key to an
unauthorized person. We recom
mend that you carry the flat key safely w ith you (e.g. in your wallet) so that it is always handy, if needed. This key has the same function as the master key.
