headlamp CADILLAC XLR 2008 1.G Owner's Manual

Headlamp aiming is done with the low-beam headlamps.
The high-beam headlamps are correctly aimed if the
low-beam headlamps are aimed properly.
The headlamp aiming
device is under the hood
near the headlamps.
Adjustment screws can be turned with an E8 Torx
®
socket or T15 Torx screwdriver.
Headlamp Vertical Aiming
To properly prepare the vehicle for vertical headlamp
aiming seeHeadlamp Aiming on page 6-47for
more information.
To adjust the vertical aim, do the following:
Notice:Horizontal aiming must be performed
before making any adjustments to the vertical aim.
Adjusting the vertical aim rst will result in an
incorrect headlamp aim.
1. Open the hood. SeeHood Release on page 6-11
for more information.
2. Locate the aim dot on the inner projector lens of the
low-beam headlamp.
3. Measure the distance from the ground to the aim
dot on each low-beam headlamp. Record this
distance.
6-48

4. At the wall or other at surface, measure from the
ground upward (A) to the recorded distance from
Step 3 and mark it.
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. Draw or tape a horizontal line (B) on the wall or at
surface 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 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 6 mm
male hex.
8. Turn the vertical
aiming screw until the
headlamp beam is
aimed to the horizontal
tape line.
6-49

9. The top edge of the cut-off should be positioned at
the bottom edge of the horizontal tape line.
10. 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.
11. Repeat Steps 7 through 9 for the opposite
headlamp.Bulb Replacement
It is recommended that all bulbs be replaced by your
dealer/retailer.

If you need to replace any of your wheels, wheel bolts or
wheel nuts, replace them only with new GM original
equipment parts. This way, you will be sure to have the
right wheel, wheel bolts, and wheel nuts for your vehicle.
{CAUTION:
Using the wrong replacement wheels, wheel
bolts, or wheel nuts on your vehicle can be
dangerous. It could affect the braking and
handling of your vehicle, make your tires lose
air and make you lose control. You could have
a collision in which you or others could be
injured. Always use the correct wheel, wheel
bolts, and wheel nuts for replacement.
Notice:The wrong wheel can also cause problems
with bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper height,
vehicle ground clearance, and tire clearance to
the body and chassis.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after a time. The wheel
could come off and cause a crash. When
you change a wheel, remove any rust or
dirt from places where the wheel attaches
to the vehicle. In an emergency, you can
use a cloth or a paper towel to do this;
but be sure to use a scraper or wire brush
later, if you need to, to get all the rust or
dirt off.
{CAUTION:
Never use oil or grease on studs or the threads
of the wheel nuts. If you do, the wheel nuts
might come loose and the wheel could fall off,
causing a crash.
