Different Size Tires and Wheels
If you add wheels or tires that are a different size
than your original equipment wheels and tires, this
may affect the way your vehicle performs, including
its braking, ride and handling characteristics,
stability, and resistance to rollover. Additionally,
if your vehicle has electronic systems such as,
anti-lock brakes, traction control, and electronic
stability control, the performance of these systems
can be affected.{CAUTION:
If you add different sized wheels, your
vehicle may not provide an acceptable
level of performance and safety if tires
not recommended for those wheels are
selected. You may increase the chance
that you will crash and suffer serious
injury. Only use GM specic wheel and
tire systems developed for your vehicle,
and have them properly installed by a
GM certied technician.
SeeBuying New Tires on page 351and
Accessories and Modications on page 280for
additional information.
353

{CAUTION:
Changing a tire can be dangerous. The
vehicle can slip off the jack and roll over
or fall on you or other people. You and
they could be badly injured or even killed.
Find a level place to change your tire.
To help prevent the vehicle from moving:
1. Set the parking brake rmly.
2. Put an automatic transaxle shift lever
in PARK (P), or shift a manual
transaxle to FIRST (1) or REVERSE (R).
3. Turn off the engine and do not restart
while the vehicle is raised.
4. Do not allow passengers to remain in
the vehicle.
To be even more certain the vehicle will not
move, you should put blocks at the front
and rear of the tire farthest away from the
one being changed. That would be the tire
on the other side, at the opposite end of
the vehicle.When you have a at tire, use the following
example as a guide to assist you in the placement
of wheel blocks.
The following information will tell you how to use
the jack and change a tire.
359

The tools you will be using include the jack (A)
and wheel wrench (B).You will need to turn the plastic wheel nut
counterclockwise to loosen the wheel wrench
from the jack.
363

8. Put the compact spare tire near the at tire.
{CAUTION:
Getting under a vehicle when it is jacked
up is dangerous. If the vehicle slips off
the jack you could be badly injured or
killed. Never get under a vehicle when
it is supported only by a jack.
{CAUTION:
Raising your vehicle with the jack
improperly positioned can damage the
vehicle and even make the vehicle fall.
To help avoid personal injury and vehicle
damage, be sure to t the jack lift head
into the proper location before raising
the vehicle.9. Raise the vehicle by turning the jack handle
clockwise. Raise the vehicle far enough off
the ground so there is enough room for
the compact spare tire to t under the vehicle.
10. Remove all of the
wheel nuts.
366

12. Place the compact spare tire on the
wheel-mounting surface.
{CAUTION:
Never use oil or grease on studs or nuts.
Because the nuts might come loose.
The vehicle’s wheel could fall off, causing
a serious accident.
13. Reinstall the wheel nuts with the rounded end
of the nuts toward the wheel. Tighten each nut
by hand until the wheel is held against the hub.
14. Lower the vehicle by turning the jack handle
counterclockwise. Lower the jack completely.
{CAUTION:
Incorrect wheel nuts or improperly
tightened wheel nuts can cause the wheel
to come loose and even come off. This
could lead to an accident. Be sure to use
the correct wheel nuts. If you have to
replace them, be sure to get new GM
original equipment wheel nuts. Stop
somewhere as soon as you can and have
the nuts tightened with a torque wrench
to the proper torque specication. See
Capacities and Specifications on page 390
for wheel nut torque specication.

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.
Add-on equipment can drain your vehicle’s
battery, even if your vehicle is not operating.
Your vehicle has an airbag system. Before
attempting to add anything electrical to your
vehicle, seeServicing Your Airbag-Equipped
Vehicle on page 82.
Headlamp Wiring
The headlamp wiring is protected by fuses.
Should your headlamps fail to function, have
your headlamp system 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 or ice, the wiper will stop
until the motor cools. If the overload is caused
by some electrical problem, have it xed.
Power Windows and Other
Power Options
Fuses in the fuse block protect the power windows.
When the current load is too heavy, the fuse opens
protecting the circuit until the problem is xed.
383

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected
from short circuits by a combination of fuses,
circuit breakers and fusible thermal links.
This greatly reduces the chance of damage
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.
There are two fuse blocks in your vehicle: the oor
console fuse block and the engine compartment
fuse block.
There is one additional fuse located in the back of
the vehicle near the battery.
Floor Console Fuse Block
The oor console fuse block is located on the
passenger’s side of the oor console behind the
forward panel. The panel has three clips. Pull
the panel to disconnect the three clips, and access
the fuses. Use the fuse puller to remove fuses.
