Headlamp Aiming
Your vehicle has the composite headlamp system. These
headlamps have horizontal and vertical aim indicators.
The aim has been pre-set at the factory and should need
no further adjustment.
If your vehicle is damaged in an accident and the
headlamp aim seems to
be affected, see your Aurora
retailer. Headlamps on damaged vehicles may require
recalibration
of the horizontal aim by your Aurora retailer.
To check the aim, the vehicle should be properly
prepared as follows:
The vehicle must have all four tires on a perfectly
level surface.
0 The vehicle should not have any snow, ice, or mud
attached to it.
There should not be any cargo or loading of vehicle,
except
it should have a full tank of gas and one
person or
160 pounds (75 kg) on the driver’s seat.
Tires should be properly inflated.
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.
State inspection stations will allow a vertical reading of
plus
0.76 degrees or minus 0.76 degrees from the center
of the bubble.
It is recommended that the upper limit not exceed plus
0.4 degrees from the center of the bubble. Other drivers
may flash their bright lights at you if your adjustment is
much above plus
0.4 degrees.
If you find that the headlamp aiming needs adjustment,
follow these steps:

Start with the vertical headlamp aim. Don't try to adjust
the horizontal aim first. Adjustment screws can be
turned with an
E8 Torx@socket or T15 Torx screwdriver.
1. Check the vertical aim for each headlamp and adjust
it as necessary.
Turn the vertical aiming screw until
the bubble in the level is centered at
0 (zero).
2. Now adjust the horizontal aim. Check the horizontal
aim for each headlamp and adjust
it as necessary.
Turn the horizontal aiming screw until the pointer is
lined up with the
0 (zero).
is still correct after the horizontal aim adjustment.
Readjust, if necessary.
3. Now, re-check the vertical aim, to make sure it

NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer/odometer
calibration, headlamp aim, bumper height, vehicle
ground clearance and tire or tire chain clearance
to the body and chassis.
See
“Changing a Flat Tire” in the Index for more
information.

’ A CAUTION: I
Putting a used wheel on your vehicle is
dangerous. You can’t know how it’s been used or
how many miles it’s been driven. It could
fail
suddenly and cause an accident. If you have to
replace
a wheel, use a new GM original
equipment wheel.
Tire Chains
NOTICE:
Use tire chains only where legal and only when
you must. Use only
SAE Class ccS” type chains
that are the proper size for your tires. Install
them on the front tires and tighten them
as
tightly as possible with the ends securely
fastened. Drive slowly and follow the chain
manufacturer’s instructions.
If you can hear the
chains contacting your vehicle, stop and retighten
them.
If the contact continues, slow down until it
stops. Driving too fast or spinning the wheels
with chains on will damage your vehicle.

Electrical System
Add-on Electrical Equipment
I NOTICE:
Don’t add anything electrical to your Aurora
unless
you check with your retailer first. Some
electrical equipment can damage your vehicle and the damage wouldn’t be covered by your
warranty. Some add-on electrical equipment
can keep other components from working
as
they should.
Your vehicle has an air bag system. Before attempting to
add anything electrical to your Aurora, see “Servicing
Your Air Bag-Equipped Aurora’’ in the Index.
Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the wiring harness. An electrical overload will cause the
lamps to go on and
off, or in some cases to remain off.
If this happens, have your headlamp system checked
right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by an internal
circuit breaker and a fuse in the fuse panel on the other
side of the instrument panel. If the motor overheats due
to heavy snow, etc., the wiper will stop until the motor
cools.
If the overload is caused by some electrical
problem, have it fixed.
Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power
windows and other power accessories. When the current
load is too heavy, the circuit breaker opens and closes,
protecting the circuit until the problem is fixed.
