Headlamp Aiming
Your vehicle has a visual optical headlamp aiming
system equipped with horizontal aim indicators. The aim
has been preset at the factory and should need no
further adjustment. This is true even though your
horizontal aim indicators may not fall exactly on the
“0 (zero) marks on their scales.
If your vehicle is damaged in an accident, the headlamp
aim may be affected. Aim adjustment to the low beam
may be necessary
if it is difficult to see lane markers (for
horizontal aim),
or if oncoming drivers flash their high
beams at you (for vertical aim).
If you believe your
headlamps need to be re-aimed, we recommend that
you take your vehicle to your dealer for service.
However, it is possible for you to re-aim your headlamps
as described
in the following procedure.
Notice: To make sure your headlamps are aimed
properly, read all the instructions before beginning.
Failure to follow these instructions could cause
damage to headlamp parts.
The vehicle should be properly prepared as follows:
The vehicle should be placed so the headlamps are
25 ft. (7.6 m) from a light colored wall or other flat
surface.
The vehicle must have all four tires on a perfectly
level surface which is level all the way to the wall
or other flat surface.
The vehicle should be placed so it is perpendicular
to the wall or other flat surface.
The vehicle should not have any snow, ice or mud
attached to it.
The vehicle should be fully assembled and all other
work stopped while headlamp aiming is being done.

Headlamp Vertical Aiming
Notice: Horizontal aiming must be performed
before making any adjustments to the vertical aim.
Adjusting the vertical aim first will result in an
incorrect headlamp aim.
1. Find the aim dot on the lens of the low beam
lamps.
2. Measure the distance from the ground to the aim
dot on each lamp;
if left low beam, subtract two
inches. Record this distance.
3. At the wall or other flat surface, measure from the
ground upward the recorded distance from Step
2
and draw or tape a horizontal line the width of
the vehicle.

.-
4. Turn on the low-beam headlamps and place a
piece of cardboard or equivalent in front of the
headlamp not being aimed. This should allow only
the beam of light from the headlamp being
aimed to be seen on the flat surface.
Notice: Do not cover a headlamp to improve beam
cut-off when aiming. Covering a headlamp may
cause excessive heat build-up which may cause
damage to the headlamp.
