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.
