Adjusting Headlamp Aim (Halogen)
Correct headlamp adjustment is
extremely important. To check and
readjust a headlamp follow steps 1
through 7. Please note:
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):
•
Horizontal aim will change and
must be corrected as described
below, whenever a vertical
adjustment is made.
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
1
should be 47 /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.

. 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.
"0"
The indicator (6) in the sight glass should align with the
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).

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