Adjusting Headlamp
Correct headlamp adjustment is
extremely important. To check and
readjust a headlamp, follow steps 1
through 7. Please note:
•
Adjustments to low beam
simultaneously aim the high beam.
•
Vehicle should have a normal
trunk load.
•
Vertical aim adjustments
change horizontal aim.
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 (8) 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
49
5
/
8
inches (1260 mm).
3. Move vehicle on the level
surface 25 feet (7.6 m) straight
back from the wall.
4. Open hood, depress latch (5)
and remove access cover (4)
from the headlamp (left side
only).
5. Vertical headlamp aim
(low beams on): Turn adjusting
screw (2) (counterclockwise to
adjust headlamp downward,

the level (6) is centered on the "0"
mark.
