Adjusting Headlamp
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
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.
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
3
/
8
inches
(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. Vertical headlamp aim (low beams
on):
Turn adjusting screw (3) (coun-
terclockwise to adjust headlamp
downward, clockwise upward) until
bubble in the level (4) is centered on
the "0" mark.
Graduations: 0.18° pitch.
