Headlamp Aiming
Your vehicle has a visual optical headlamp aiming
system equipped with horizontal aim indicators. The
aim has been pre
-set at the factory and should need
no further adjustment. This is true even though your
horizontal aim indicators may not fall exactly on the
ª0º (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 flash 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.

6-38
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
flat surface.

The vehicle must have all four tires on a perfectly
level surface which is level all the way to the wall or
other flat surface.

The vehicle should be placed so it is perpendicular to
the wall or other flat 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 inflated.

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 horizontal
(left/right) adjustment, follow the horizontal aiming
procedure. If you believe your headlamps need only
vertical (up/down) adjustment, follow only the vertical
aiming procedure.
Adjustment screws can be turned with an E8 Torx

socket or T15 Torx screwdriver.

Headlamp Horizontal Aiming
Turn the horizontal aiming
screw (A) until the indicator
(B) is lined up with zero.
Once the horizontal aim
is adjusted, then adjust
the vertical aim.
Headlamp Vertical Aiming
1. Find the aim dot on the lens of the lamps.
2. Measure the distance from the ground to the aim dot
on each lamp. Record this distance.
3. At the wall or other flat surface, measure from the
floor to the recorded distance and draw a horizontal
line the width of the vehicle.

4. Turn on the low beam headlamps and cover the lamp
not being evaluated. The ambient light should allow

Tires
Your new vehicle comes with high-quality tires made by
a leading tire manufacturer. If you ever have questions
about your tire warranty and where to obtain service,
see your Cadillac Warranty booklet for details.
CAUTION:
Poorly maintained and improperly used tires
are dangerous.

Overloading your tires can cause
overheating as a result of too much friction.
You could have an air
-out and a serious
accident. See ªLoading Your Vehicleº in
the Index.
CAUTION: (Continued)
CAUTION: (Continued)

Underinflated tires pose the same danger as
overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked
when your tires are cold.

Overinflated tires are more likely to be
cut, punctured or broken by a sudden
impact
-- such as when you hit a pothole.
Keep tires at the recommended pressure.

Worn, old tires can cause accidents. If your
tread is badly worn, or if your tires have
been damaged, replace them.
See ªInflation -- Tire Pressureº in this section
for inflation pressure adjustment for higher
speed driving.
