try to service any of the system components,
you could be seriously injured. Have your
dealer or a qualied technician service them.
Your vehicle has HID low-beam headlamps. After your
vehicle’s HID headlamp bulb has been replaced,
you may notice that the beam is a slightly different
shade than it was originally. This is normal.

Windshield Replacement

Display (HUD) system. If you ever have to get your
windshield replaced, be sure to get one that is designed
for HUD or your HUD image may look blurred or out
of focus.
5-48

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.

Electrical System
Add-On Electrical Equipment
Notice:Don’t add anything electrical to your
vehicle unless you check with your dealer rst.
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 vehicle, see
Servicing Your Airbag-Equipped Vehicle on page 1-51.
Headlamp Wiring
The headlamp wiring is protected by fuses. An electrical
overload will cause the lamps to remain off. If this
happens, have your headlamp wiring checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by a fuse and
an internal circuit breaker. 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 and not snow, etc., be sure to get it xed.
Power Windows and Other Power
Options
Circuit breakers protect the power seats, 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 xed
or goes away.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of J-Case fuses,
mini-fuses and circuit breakers. This greatly reduces the
chance of res caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical
size and rating.
If you ever have a problem on the road and do not have
a spare fuse, you can borrow one that has the same
amperage. Just pick some feature of your vehicle
that you can get along without – like the radio or
cigarette lighter – and use its fuse, if it is the correct
amperage. Replace it as soon as you can.
