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.

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):
T u rn a d j u st i n g sc re w ( 2 ) ( c o u n t e rc l oc k w i s e to a d j u st
headlamp downward, clockwise upward) until
bubble in the level (6) is centered on the “0” mark.
Graduations: 0.18° pitch.

5. Horizontal headlamp aim (Low beams on):
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
adj ustment, h ave the system ch ecked a t your a ut horized
Mercedes-Benz Center.
