Adjusting Headlamp Aim
(Xenon)
Correct headlamp adjustment is extremely important. To ch eck and readjust a headlamp, follow steps 1 through 5.
Please note:
• Low beam adjustments 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 feet (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 "T" square and a carpenter's leve l, 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 47
1/4inches(1198mm).
3 . Mark a horizontal centerline (9) at a height of 221/2 inches (570 mm) on the test screen. It must be at a 90° angle
to the vertical centerline.
4 . Open hood.
5 . Vertical headlamp aim (low beams on):
Turn adjusting screws (1 and 2) equally in direct ion and turns (counterclockwise to adjust headlamp downward,
clockwise upward) until the headlamps (low beam) illuminate 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 ad justment, have the system checked at your authorized
Mercedes-Benz dealer.
