Adjusting Headlamp Aim
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.
• Adjustments to low beam
simultaneously aim the high beam.
• 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.
2. Using a "T" square and a carpenter's
level, align and mark a vertical
centerline (10) on the test screen using
the outer reference point (low beam)
found on each headlamp lens. As a
check, the distance between
centerlines should be 52
(1328 mm).
3. Move vehicle on the level surface 25
feet (7.6 m) straight back from the
wall.
4. Open hood, depress latch (1) and
remove access cover (2) from the
headlamp,
5. Turn key in steering lock to position
2.
6. Vertical headlamp aim (low beams
on): Turn adjusting screw (3) (coun-
terclockwise to adjust headlamp
downward, clockwise upward) until
3
/ inches bubble in the level (4) is centered on
8
the "0" mark.
