Adjusting Headlamp Aim
(Xenon)
Correct headlamp adjustment is
extremely important. To check and
readjust a headlamp, follow steps 1
through 7. Please note:
• Low beam adjustments
simultaneously aim the high
beam.
• Vehicle should have a normal
load.
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 (11) 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 54
(1384 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 (13) on
high beam lens. Subtract approx. 2
inches (53 mm) from
measurement, and mark a
horizontal centerline (12) on the test
screen at the resulting height from
the floor. It must be at a 90° angle
1
/
inches
to the vertical centerline.
