Adjusting Headlamp Aim
(Halogen)
Correct headlamp adjustment is extremely important. To check and readjust a headlamp do the following:
•
•
•
Horizontal aim will change and must be corrected as described below, whenever a vertical adjustment is made.
Low beam adjustments simultaneously aim the high beam and fog lamp.
Vehicle should have a normal trunk load.
1
. Park vehicle on level surface approximately 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.
. Using a "T" square and a carpenter's level, align and mark avertical centerline (8) on the test screen using the
2
outer
reference point (low centerlines should be 47 1/4 inches (1198 mm).
. Move vehicle on the level surface 25 feet (7.6 m) straight back from the wall.
. Open hood, depress latch (1), and remove access cover (2) from the headlamp.
. Vertical headlamp aim (low beams on): Turn adjusting screw (3) (counterclockwise to adjust headlamp downward,
clockwise upward) until bubble in the level (4) is centered on the "0" mark. Graduations: 0.18° pitch.

. Horizontal headlamp aim (low beams on):
Turn adjusting screw (5) (Right front headlamp: counterclockwise to adjust to the left, clockwise to the right; left
front headlamp: counterclockwise to adjust to the right, clockwise to the left.) until the headlamps (low beam)
illuminate the test screen as shown. The vertex of the angle formed in each beam image should align with the
vertical centerline (8) of each lamp. The left and right headlamps must be adjusted individually.

. The indicator (6) in the sight glass should align with the "0" mark after any horizontal adjustment. If it does not,
slide the "0" mark on the scale (7) until it aligns with the indicator (6). Graduations: 0.38° pitch.
. Reinstall access cover(2).
