2005 CADILLAC XLR headlamp

You can run the engine to keep warm, but be careful.
{CAUTION:
Snow can trap exhaust gases under your
vehicle. This can cause deadly CO (carbon
monoxide) gas to get inside. CO could
overcome you and kill you. You cannot see it
or smell it, so you might not know it is in your
vehicle. Clear away snow from around the
base of your vehicle, especially any that is
blocking your exhaust pipe. And check around
again from time to time to be sure snow does
not collect there.
Open a window just a little on the side of the
vehicle that is away from the wind. This will
help keep CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little
faster than just idle. That is, push the accelerator
slightly. This uses less fuel for the heat that you get and
it keeps the battery charged. You will need a
well-charged battery to restart the vehicle, and possibly
for signaling later on with your headlamps. Let the
heater run for a while.

What to Use
To add lubricant when the level is low, use SAE 75W–90
Synthetic Gear Lubricant (GM Part No. 12378261) or
equivalent meeting GM Specication 9986115. To
completely rell after draining, add 4 ounces (118 ml) of
Limited-Slip Differential Lubricant Additive (GM Part
No. 1052358) or equivalent. Then ll to the bottom of the
ller plug hole with the Synthetic Gear Lubricant.
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 ash 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 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.
6-42

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 inated.
Start the vehicle and rock it to level the suspension.
Headlamp aiming is done with the vehicle low beam
lamps. The high beam lamps will be correctly aimed if
the low beam lamps are aimed properly.
The headlamp aiming
devices are under the
hood near the headlamps.
If you believe your headlamps need vertical (up/down)
adjustment, follow the vertical aiming procedure.
Adjustment screws can be turned with an E8 Torx
®
socket or T15 Torx screwdriver.
Headlamp Vertical Aiming
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. 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 low beam lamp. Record this distance.
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.
6-43

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.
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.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.
Bulb Replacement
It is recommended that all bulbs be replaced by
your dealer.

Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
carefully at the factory to give you the longest tire life
and best overall performance.
If you notice unusual tire wear or your vehicle pulling one
way or the other, the alignment may need to be reset. If
you notice your vehicle vibrating when driving on a
smooth road, your wheels may need to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted
or corroded. If wheel nuts keep coming loose, the
wheel, wheel bolts and wheel nuts should be replaced.
If the wheel leaks air, replace it (except some
aluminum wheels, which can sometimes be repaired).
See your dealer if any of these conditions exist.
Your dealer will know the kind of wheel you need.
Each new wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted
the same way as the one it replaces.
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.
