Wa r n i n g !
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.

Turn adjusting screw (1) (Right front headlamp:
counterclockwise to adjust to the left, clockwise to
the right; left front headlamp: 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. This indicator (7) in the sight glass should align
with the “0” mark after any horizontal adjustment.
If it does not, depress latch (5) and remove access
cover (4) from the headlamp (left side only). Insert
and turn screwdriver on adjuster (3) until scale (7)
is centered on the “0” mark.
Graduations: 0.38° pitch.
7. Reinstall access cover (4).
Note:
If it is not possible to obtain a proper headlamp
adjustment, have the system checked at your authorized
Mercedes-Benz Center.

Engine cleaning
Prior to cleaning the engine compartment make sure to
protect electrical components and connectors from the
intrusion of water and cleaning agents.
Corrosion protection, such as MB Anticorrosion Wax
should be applied to the engine compartment after
every engine cleaning. Before applying, all control
linkage bushings and joints should be lubricated. The
poly-V-belt and all pulleys should be protected from any
wax.
Ve h i c l e w a s h i n g
Do not use hot water or wash your vehicle in direct
sunlight. Use only a mild car wash detergent, such as
Mercedes-Benz approved Car Shampoo.
Thoroughly spray the vehicle with a diffused jet of
water. Direct only a very weak spray towards the
ventilation intake. Use plenty of water and rinse the
sponge and chamois frequently.
Rinse with clear water and thoroughly wipe dry with a
chamois. Do not allow cleaning agents to dry on the
finish.If the vehicle has been run through an automatic car
wash – in particular one of the older installations -
rewipe the recessed sections in the taillamps (designed
to prevent soiling) if necessary. No solvents (fuels,
thinners etc.) must be used.
In the winter thoroughly remove all traces of road salt
as soon as possible.
When washing the underbody, do not forget to clean the
inner sides of the wheels.
Ornamental moldings
For regular cleaning and care of very dirty chrome-
plated parts, use a chrome cleaner.
Headlamps, taillamps, turn signal lenses
Use a mild car wash detergent such as Mercedes-Benz
approved Car Shampoo, with plenty of water.
To prevent scratches, never apply strong force and use
only a soft, non-scratchy cloth when cleaning the lenses.
Do not attempt to wipe dirty lenses with a dry cloth or
sponge.
