Adjusting headlamp aim
Correct headlamp adjustment is extremely important.
To check and readjust a headlamp, follow steps 1
through 7.
Please note:
• High beam adjustments simultaneously aim the low
beam.
• Vehicle should have a normal trunk load. 1. Park vehicle on level surface approximately 6 inches
(152 mm) from a vertical test screen or wall. The
centerline of the vehicle must be at a 90 ° angle to
the test screen.
2. (High beams on):
Using a carpenter’s level, align and mark a vertical
centerline (1) on the test screen for each headlamp
lens at a distance of 25
3/4inches (654 mm) from
the vertical centerline. As a check, the distance
between centerlines should be 51
1/2inches
(1308 mm). The star emblem on the hood may be
used to determine the vehicle centerline. If the
distance does not check, have the system verified at
an authorized Mercedes-Benz Light Truck Center.
3. Move vehicle on the level surface 25 feet (7.6 m) straight back from the wall.
4. Open hood.

5. (High beams on):
Simultaneously turn adjusting screws (1 and 2 on
page 261 or 262) counterclockwise to adjust
headlamp downward, clockwise upward) equally
until bubble in the level (7 on page 261) is centered
on the “0” mark.
Graduations:
screw 1: 0.50 ° pitch,
screw 2: 0.67 ° pitch.
6. Horizontal headlamp aim (High beams on): Turn adjusting screw (2) (left headlamp:
counterclockwise to adjust to the left, clockwise to
the right [right headlamp in opposite direction])
until the headlamp (high beam pattern) is centered
about the vertical centerline (1) as shown.
The left and right headlamps must be adjusted
individually. 7. For proper aim, the indicator (8 on page 261) should
align with the “0” mark after horizontal adjustment.
Graduations: 0.33 ° pitch.
Note:
If it is not possible to obtain a proper headlamp
adjustment, have the system checked at your authorized
Mercedes-Benz Light Truck Center.
