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 or tire chain clearance
to the body and chassis.Whenever a wheel, wheel bolt or wheel nut is
replaced on a dual wheel setup, check the wheel
nut torque after 100, 1,000 and 6,000 miles
(160, 1 600 and 10 000 km) of driving. For proper
torque, see “Wheel Nut Torque” underCapacities
and Specications on page 398.
SeeChanging a Flat Tire on page 366for more
information.Used Replacement Wheels
{CAUTION:
Putting a used wheel on your vehicle is
dangerous. You cannot know how it has
been used or how far it has been driven.
It could fail suddenly and cause a crash.
If you have to replace a wheel, use a
new GM original equipment wheel.

Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your dealer
rst. Some electrical equipment can damage
your vehicle and the damage would not
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, seeServicing Your Airbag-Equipped
Vehicle on page 96.
Headlamp Wiring
The headlamp wiring is protected by fuses in the
engine compartment fuse block. An electrical
overload will cause the lamps to flicker on and off,
or in some cases to remain off. If this happens,
have your headlamp wiring checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by a
circuit breaker and a fuse. If the motor overheats
due to heavy snow, etc., the wiper will stop
until the motor cools. Although the circuit is
protected from electrical overload, overload due
to heavy snow, etc., may cause wiper linkage
damage. Always clear ice and heavy snow from
the windshield before using the windshield wipers.
If the overload is caused by some electrical
problem and not snow, etc., be sure to get it fixed.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected
from short circuits by a combination of fuses
and circuit breakers. This greatly reduces
the chance of fires 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.
