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.
However, 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 the vehicle is taken to your
dealer for service if the headlamps need to be
re-aimed. It is possible however, 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.
The vehicle must have all four tires on a
perfectly level surface which is level all
the way to the wall.
The vehicle should be placed so it is
perpendicular to the wall.
The vehicle should not have any snow, ice, or
mud on 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) sitting on the driver’s seat.
Tires should be properly inated.
Headlamp aiming is done with the low-beam
headlamps. The high-beam headlamps will be
correctly aimed if the low-beam headlamps
are aimed properly.
388

To adjust the vertical aim, do the following:
1. Open the hood. SeeHood Release on
page 345for more information.
Find the aim dot on the lens of the
low-beam lamp.
2. Locate the aim dot on the lens of the
low-beam headlamp.
3. Measure the distance from the ground to the
aim dot on the lamp. Record the distance.4. At the wall measure from the ground
upward (A) to the recorded distance
from Step 3 and mark it.
5. Draw or tape a horizontal line (B) on the wall
the width of the vehicle at the height of the
mark in Step 4.
6. 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.
389

7. Locate the vertical headlamp aiming screws,
which are under the hood, near the
headlamps. Turn the vertical aiming screw
until the headlamp beam is aimed to the
horizontal tape line.
The adjustment screws can be turned with a
6 mm hex key bit socket ora6mmhexkey.8. Turn the vertical aiming screw until the
headlamp beam is aimed to the horizontal
tape line. Turn it clockwise or
counterclockwise to raise or lower the angle
of the beam.
9. Make sure that the light from the headlamp is
positioned at the bottom edge of the horizontal
tape line. The lamp on the left (A) shows
the correct headlamp aim. The lamp on the
right (B) shows the incorrect headlamp aim.
10. Repeat Steps 7 through 9 for the opposite
headlamp.
