Low windshield and headlamp washer system fluid
level warning lamp
With the key in steering lock position 2, the
warning lamp comes on. It should go out
when the engine is running.
If the warning lamp does not go out after starting the
engine, or if it comes on while driving, the level of the
reservoir has dropped to approx. 1/3 of the total volume.
The reservoir should be refilled with MB Windshield
Washer Concentrate “S” and water (or commercially
available premixed windshield washer solvent/
antifreeze, depending on ambient temperature - see
page 88) at the next opportunity. The reservoir for the
windshield and headlamp washer systems is located in
the engine compartment.Low engine oil level warning lamp
With the key in steering lock position 2, the
oil level warning lamp comes on. It should
go out immediately when the engine is
running.
If the warning lamp does not go out after starting the
engine, or comes on with the engine running and at
operating temperature, the engine oil level has dropped
to approximately the minimum mark on the dipstick.
When this occurs, the warning lamp will first come on
intermittently and then stay on if the oil level drops
further.
If no leaks are noted, continue to drive to the nearest
service station where the engine oil should be topped to
the “full” mark on the dipstick with an approved oil.
The low engine oil level warning light should not be
ignored. Extended driving with the light illuminated
could result in serious engine damage that is not
covered by the Mercedes-Benz Limited Warranty.
In addition to the warning lamp, the engine oil level
should be periodically checked with the dipstick, for
example during a fuel stop, or before a long trip,
see page 222.

cluster displayPractical hints Car care Index Charge indicator lamp
Should the charge indicator lamp fail to
come on prior to starting when the key is in
steering l ock position 2 or sh ou ld it fa il to go
out after starting or during operation, this indicates a
malfunction which must be repaired immediately at an
authorized Mercedes-Benz Center.
If the charge indicator lamp comes on, or a loss of power
steering assistance is noticeable while the engine is
running, this may indicate that one of the two poly-V-
belts has broken. Should this condition occur, the poly-
V-belt must be replaced before continuing to operate the
vehicle. Otherwise, the engine may overheat due to an
inoperative water pump which may result in damage to
the engine.
Do not continue to drive the vehicle with the charge
indicator lamp illuminated. Doing so could result in
serious engine damage that is not covered by the
Mercedes-Benz Limited Warranty.Exterior lamp failure indicator lamp
With the key in steering lock position 2, an
indicator lamp comes on. It should go out
when the engine is running.
If the warning lamp does not go out after starting the
engine, or if it comes on while driving, this lamp
indicates a failure in the parking lamp, taillamp, stop
lamp, or low beam headlamp.
If a n exterior lamp fa ils, the indica tor lamp will com e on
only when that lamp is switched on.
If a brake lamp fails, the lamp failure indicator will
come on when applying the brake and stays on until the
engine is turned off.
Note:
If additional lighting equipment is installed (e.g.
auxiliary headlamps etc.) be certain to connect into the
fuse before the failure indicator monitoring unit in
order to avoid damaging the system.

Because of high voltage in Xenon lamps, it is
dangerous to replace the bulb or repair the lamp
and its components. We recommend that you have
such work done by a qualified technician.

Adjusting headlamp aim
Correct headlamp adjustment is extremely important.
To check and readjust a headlamp, follow steps 1
through 7. Please note:
• Adjustments to low beam simultaneously aim the
high beam.
• Vehicle should have a normal trunk load.
• Vertical aim adjustments change horizontal aim.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
49
5/8 inches (1260 mm). If the distance does not
check, have the system verified by an authorized
Mercedes-Benz Center.
3. Open hood.
4. Vertical headlamp aim (Low beams on):
Turn adjusting screw (2) (counterclockwise to adjust
headlamp downward, clockwise upward) until
bubble in the level (6) is centered on the “0” mark.
Graduations: 0.18° pitch.
