Headlamp Aiming
The vehicle has a visual optical headlamp aiming
system. The aim has been preset at the factory and
should need no further adjustment
If the vehicle is damaged in an accident, the headlamp
aim may be affected and adjustment may be
necessary.
If oncoming vehicles ¯ash their high beams at you, this
may also mean the vertical aim needs to be adjusted.
It is recommended that you take the vehicle to your
dealer for service if the headlamps need to be re-aimed.
However, it is possible for you to re-aim the headlamps
as described in the following procedure.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 ¯at
surface.
·The vehicle must have all four tires on a perfectly
level surface which is level all the way to the wall
or other ¯at surface.
·The vehicle should be placed so it is perpendicular
to the wall or other ¯at 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.
·The vehicle should be normally loaded with a
full tank of fuel and one person or 160 lbs (75 kg) on
the driver's seat.
·Tires should be properly in¯ated.

Headlamp aiming is done with the vehicle's low-beam
lamps. The high-beam lamps will be correctly aimed
if the low-beam lamps are aimed properly.
The vertical headlamp aiming screws are under the
hood near the headlamps.
Adjustment screws can be turned with an E8 Torx
ž
socket or T15 Torxžscrewdriver.
Headlamp Vertical Aiming
1. Find the aim dot on the lens of the low beam lamp.
2. Measure the distance from the ground to the aim
dot on the lamp. Record the distance.
5-57

3. At the wall or other ¯at 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 ¯at 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.
5-58

5. Turn the vertical aiming screw until the headlamp
beam is aimed to the horizontal tape line. The top
edge of the cut-off should be positioned at the
bottom edge of the horizontal tape line.
6. Repeat steps 4 and 5 for the opposite headlamp.
