Adjusting Headlamp - Mercedes-Benz E320 Operator's Manual

Adjusting Headlamp

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 trunk
load.
• Vertical aim adjustments change
horizontal aim.
1. Park vehicle on level surface approx.
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. Using a "T" square and a carpenter's
level, align and mark a vertical
centerline (8) on the test screen using
the outer reference point (low beam)
as found on each headlamp lens.
As a check, the distance between
centerlines should be 49
(1250 mm).
3. Move vehicle on the level
surface 25 feet (7.6 m) straight
back from the wall.
4. Open hood.
5. Vertical headlamp aim
(low beams on):
Turn adjusting screw (2) (coun-
terclockwise to adjust headlamp
downward, clockwise upward) until
bubble in the level (8) is centered
on the "O" mark.
Graduations: 0.18° pitch.
