lock MERCEDES-BENZ C-Class 2000 W202 Repair Manual

Winter Driving
Have your car winterized at your authorized Mercedes-Benz dealer before the onset of winter.
• Change the engine oil if the engine contains an oil which is not approved for winter operation.
For viscosity (SAE/CCMC class) and filling quantity, see Capacities: Fuels, Coolants,
Lubricants etc. in Index.
• Check engine coolant anticorr osion/antifreeze concentration.
• Additive for the windshield washer and headl amp cleaning system: Add MB Concentrate "S"
to a premixed windshield washer solvent/ant ifreeze which is formulated for below freezing
temperatures (see Index).
• Test battery: Battery capacity drops with dec reasing ambient temperature. A well charged
battery helps to ensure that the engine can be started, even at low ambient temperatures.
• Tires: We recommend M+S rated radial-ply tires on all four wheels for the winter season.
Observe permissible maximum speed for M+S rated radial-ply tires and the legal speed limit.

Note:
In winter operation, the maximum effectiveness of the Antilock Brake System (ABS), Acceleration Slip Regulation
(ASR) or the Electronic Stab ility Program (ESP) can only be achieved with M+S rated radial-ply tires and/or snow
chains recommended by Mercedes-Benz. Snow chains maximize performance.


Snow Chains
Use only snow chains that are tested and recommended by Mercedes-Benz. Your authorized Mercedes-Benz
dealer will be glad to advise you on this subject. Ch ains should only be used on the rear wheels.
Follow the manufacturer's mounting instructions. Snow ch ains should only be driven on snow covered roads at
speeds not to exceed 30 mph (50 km/h). Remove chains as soon as possible when driving on roads without snow.
For tips on driving on slippery winter roads, refer to In dex. Vehicles with Acceleration Slip Regulation (ASR) or
Electronic Stability Program (ESP): When driving with snow chains, press the ASR or ESP control switch, refer to
Index.


Model C 43 AMG

Important !
Use of snow chains is permissible only on winter tire size 215/45 R 17 H M+S. Refer to "Rims - Tires" in section
"Technical Data" (see Index).


Travelling Abroad
Abroad, there is a widely-spread Mercedes-Benz service network at your disposal. If you plan to travel into areas
which are not listed in the index of your dealer directory, you should request pertinent information from your
authorized Mercedes-Benz dealer.

Hood






To open:
To unlock the hood, pull release lever (1) under the driver's side of the instrument panel. At the same time handle
(2) will extend out of the radiator grill (it may be necessary to lift the hood up slightly).

Caution !
To avoid damage to the windshield wiper or hood, open the hood only with wiper in the parked position. Pull handle
(2) completely out of radiator grill and open hood (do not pull up on handle).

To close:
Lower hood and let it drop into lock from a height of approx. 1 ft. (30 cm), assisting with hands placed flat on edges
of hood (3). To avoid hood damage, if hood is not fully closed, repeat closing procedure. Do not push down on hood
to attempt to fully close it.

Warning!

To help prevent personal injury, stay clear of moving parts when the hood is open and the engine is running.
Be sure the hood is properly closed before driving. When closing hood, use extreme caution not to catch
hands or fingers. The engine is equipped with a transistorized ignition system. Because of the high voltage it
is dangerous to touch any components (ignition coils, spark plug sockets, diagnostic socket) of the ignition
system
• with the engine running,
• while starting the engine,
• if ignition is "on" and the engine is turned manually.
If you see flames, steam or smoke coming from the engine compartment, or if the coolant temperature
gauge indicates that the engine is overheated, do not open the hood. Move away from vehicle and do not
open the hood until the engine has cooled. If necessary, call a fire department.

Example



Checking Coolant Level
To check the coolant level, the vehicle must be parked on level ground and the engine stopped.
Check coolant level only when coolant is cold.
The coolant level should reach the black top part of the reservoir.


Adding Coolant
If coolant has to be added, a 50/50 mixture of water and MB anticorrosion/antifreeze should be added. The drain
plugs
for the cooling system are located on the right side of the engine block and at the bottom of the radiator.
Anticorrosion/antifreeze, see Coolants in Index.

Warning!
In order to avoid possibly serious burns or injury:
•Use extreme caution when opening the hood if there are any signs of steam or coolant leaking from the
cooling system, or if the coolant temperature gauge indicates that the coolant is overheated.
•Do not remove pressure cap on coolant reservoir if engine temperature is above 194°F (90°C). Allow
engine to cool down before removing cap. The coolant reservoir contains hot fluid and is under pressure.

•Using a rag, slowly open cap approximately 1/2 turn to relieve excess pressure. If opened immediately,
scalding hot fluid and steam will be blown out under pressure.

•Do not spill antifreeze on hot engine parts. Antifreeze contains ethylene glycol which may burn if it comes
into contact with hot engine parts.

Odometer Display Field
(Models C 280 and C 43 AMG)

Turn electronic key in steering lock to position 2 and wait until the symbols and appears in the
odometer display field. Within 1 second press button 0 twice.


The following messages are available:
"OK"
"-1.0 Q" (Canada: -1.0 L)
"-1.5 Q" (Canada: -1.5L)
"-2.0 Q" (Canada: -2.0 L)
If the message "-2.0 Q" (Canada: -2.0 L) blinks and a signal sounds, add oil to upper (max) mark of the dipstick.
"HI"
The message "Hi" blinks and a signal sounds.


Do not overfill the engine.

Excessive oil must be drained or siphoned. It could cause damage to engine and catalytic converter not covered
by the Mercedes-Benz Limited Warranty.
The symbol flashes in the odometer field if a proper oil level check cannot be performed. The oil level check
can be repeated after a short while. Perform the oil level check with the dipstick, if it cannot be completed via the
odometer display field. In this case we recommend that you have the system checked at a Mercedes-Benz dealer.

Notes:
If the symbols and are continuously illuminated after pressing button 0 twice and there is no change in the
odometer display field or the low engine oil level warning lamp comes on, a malfunction has occurred to the system .
Perform the engine oil level check with the dipstick. If no oil leaks are noted continue to drive to the nearest
Mercedes-Benz dealer to have the system checked.

Automatic Transmission Fluid Level
The transmission has a permanent fill of automatic transmission fluid. Regular automatic transmission fluid
level checks and changes are not required. For this reason the dipstick is omitted. If you notice fluid leaks or
gear shifting malfunctions, have your authorized Mercedes-Benz dealer check the transmission fluid level.

Adjusting Headlamp Aim (Halogen)











Correct headlamp adjustment is
extremely important. To check and
readjust a headlamp follow steps 1
through 7. Please note:
• Horizontal aim will change and
must be corrected as described
below, whenever a vertical
adjustment is made.
• Low beam adjustments
simultaneously aim the high
beam and fog lamp.
• Vehicle should have a normal
trunk load.


1. Park vehicle on level surface approximately 25 ft. (7.6 m)
from a vertical test screen or wall. The centerline of the
vehicle must be at a 90° angle to the test screen.
2. (low beams on):
Using a carpenter's level, align and mark a vertical centerline
(8) on the test screen using the vertex of the angle formed in
each beam image. As a check, the distance between centerlines
should be 47 1/4 inches (1198 mm). If the distance does not check,
have the system verified at an authorized Mercedes-Benz dealer.
3. Open hood, depress latch (1), and remove access cover (2) from
the headlamp.
4. Vertical headlamp aim
(low beams on): Turn adjusting screw (3) (counterclockwise to adjust
headlamp downward, clockwise upward) until bubble in the level (4) is
centered on the "0" mark.
Graduations: 0.18° pitch.



5. Horizontal headlamp aim (low beams on):
Turn adjusting screw (5) (Right front headlamp: counterclockwise
to adjust to the left, clockwise to the right; left front head-
lamp: counterclockwise to adjust to the right, clockwise to the
left.) until the headlamps (low beam) illuminate the test screen
as shown. The vertex of the angle formed in each beam
image should align with the vertical centerline (8) of each lamp.
The left and right headlamps must be adjusted individually.
6. The indicator (6) in the sight glass should align with the
"0" mark after any horizontal adjustment. If it does not, slide
the "0" mark on the scale (7) until it aligns with the indicator (6).
Graduations: 0.38° pitch.
7. Reinstall access cover(2).

Note:
If it is not possible to obtain a proper headlamp adjustment, have
the system checked at your authorized Mercedes-Benz dealer.
