In most cases, you will not need to have your wheels
aligned again. However, 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.
Wl 21 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
Buick 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
Buick model. 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.

Electrical System
Add-on Electrical Equipment
I NOTICE:
Don’t add anything electrical to your Buick
unless you check with your dealer 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 Buick, see “Servicing
Your Air Bag-Equipped Buick” in the Index.
Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the lamp switch. 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 Wipers
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. 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.
Engine A/C, EGR, Relays, SIR Crank and
Safety Belt Fuses
These fuses are located behind the glove box. The fuse
holders are taped together with gray tape.
Other - uses
The Safety Belt/Chime (ICAM) Module fuse and the
Remote Keyless Entry fuse are located behind the fuse
block, above the hush panel.
The Fuel Pump, A/C CONT and the ECM fuses are
located under the hood.
