2006 PONTIAC GTO Owners Manual

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 15 ft. (4.6 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
on it.
·The vehicle should be fully assembled and all other
work stopped while headlamp aiming is being
performed.
·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 in¯ated.
·The spare tire is in its original location in
the vehicle.
Headlamp aiming is done with the vehicle's low-beam
headlamps. The high-beam headlamps will be correctly
aimed if the low-beam headlamps are aimed properly.

To adjust the vertical aim on the headlamps, do the
following:
1. Open the hood. See
Hood Release on page 5-11for more information.
2. Find the aim dot on the lens of the low-beam
headlamp.
3. Measure the distance from the ground to the aim
dot on the low-beam headlamp. Record the
distance.
4. At the wall or other ¯at surface, measure from the
ground upward the recorded distance from Step 2
and mark it.
5. Draw or tape a horizontal line the width of the
vehicle at the wall or other ¯at surface where it
was marked it Step 4.
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.
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.
7. Locate the vertical headlamp aiming screws, which
are under the hood near each headlamp assembly.
The adjustment screw can be turned with a
No. 2 Phillips head screwdriver.

8. Turn the vertical aiming screw (A) until the
headlamp beam is aimed to the horizontal tape line.
If you turn it clockwise, it will raise the beam and
if you turn it counterclockwise, it will lower the beam.
The top edge of the cut-off should be positioned
at the bottom edge of the horizontal tape line.
9. Repeat Steps 7 and 8 for the opposite headlamp.
