Adjusting Headlamp Aim
(Xenon)
Correct headlamp adjustment is
extremely important. To check and
readjust a headlamp, follow steps 1
through 5. Please note:
• Low beam adjustments
simultaneously aim the high
beam and fog lamp.
• 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 center-
lines 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. (Low beams off):
Measure the vertical height from the floor to reference point (10)
on low beam lens. Subtract approx. 2 inches (53 mm) from
measurement, and mark a horizontal centerline (9) on the
test screen at the resulting height from the floor. It must be
at a 90° angle to the vertical centerline.
4. Open hood.
5. Vertical headlamp aim (low beams on):
Simultaneously turn adjusting screws (1 and 2) equally in the
same direction (counterclockwise to adjust headlamp downward,
clockwise upward) until the headlamp (low beam)
illuminates the test screen as shown.
The left and right headlamps must be adjusted individually.
Note:
If it is not possible to obtain a proper headlamp adjustment, have
the system checked at your authorized Mercedes-Benz dealer.
