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 centerlines should be
49
1/4 inches (1250 mm). If the distance does not
check, have the system verified at an authorized
Mercedes-Benz Center.3. (Low beams off):
Measure the vertical height from the floor to
reference point (10) on high 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.

headlamp downward, clockwise upward) until the
headlamps illuminate the test screen as shown. The
vertex of the angle formed in each beam image
should align with the vertical and horizontal
centerlines (8 and 9).
The left and right headlamps must be adjusted
individually.
