Adjusting Headlamp
Correct headlamp adjustment is
extremely important. To check and
readjust a headlamp, follow steps 1
through 7. Please note:
• Low beam adjustments
simultaneously aim the high beam.
• Vehicle should have a normal trunk
load.
• Vertical aim adjustments change
horizontal aim.
1. Park vehicle on level surface approx.
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 (8) on the test screen using
the outer reference point (low beam)
as found on each headlamp lens.
As a check, the distance between
centerlines should be 49
(1250 mm).
3. Open hood.
4. Vertical headlamp aim
(low beams on):
Turn adjusting screw (2) (coun-
terclockwise to adjust headlamp
1
/ inches downward, clockwise upward) until
4
bubble in the level (8) is centered
on the "O" mark.
Graduations: 0.18° pitch.
