3. Tilt the retainer at the end of the cable to remove
the compact spare tire, so it can be pulled up
through the wheel opening.
If your vehicle is an AWD vehicle, after removing
the compact spare tire, turn the wrench clockwise to
raise the cable back up. On an AWD vehicle, you
can not store a full-size tire under the vehicle.
It should be stowed inside the vehicle by the cable
provided. See “Storing the Flat Tire on an
All-Wheel-Drive Vehicle” underStoring a Flat or
Spare Tire and Tools on page 5-83for more
information.If you have a front-wheel-drive vehicle, the hoist is
used to store a full-size or a at road tire under
the vehicle. See “Storing the Flat Tire on an
Front-Wheel-Drive Vehicle” underStoring a Flat or
Spare Tire and Tools on page 5-83for more
information.
4. Remove the compact spare tire from the cable.
If the compact spare tire will not lower, check under the
vehicle to see if the tire is hanging loose and the
cable end and spring under the wheel plate are missing.
If so, the secondary latch system is engaged. See
Secondary Latch System on page 5-81.
To continue changing the at tire, seeRemoving the
Flat Tire and Installing the Spare Tire on page 5-75.

Removing the Flat Tire and
Installing the Spare Tire
If the wheel has a center cap, use the handle of the
folding wrench to pry it off. Then, with the other end of
the folding wrench, loosen the nuts.
If your vehicle has the plastic bolt-on wheel covers,
loosen the bolts completely using the folding wrench,
and remove the wheel cover.Once the center cap and/or wheel cover are removed,
use the following steps to remove the at tire and install
the spare tire.
1. Loosen the wheel nuts
using the folding
wrench, but do not
remove them.
Turn the handle
counterclockwise about
180 degrees, then ip
the handle back to the
starting position. This
avoids taking the
wrench off the lug nut
for each turn.
Notice:If your vehicle has wheel locks and you use
an impact wrench to remove the wheel nuts, you
could damage the lock nut or wheel lock key. Do not
use an impact wrench to remove the wheel nuts if
your vehicle has wheel locks.

{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.
4. Attach the folding wrench (A) to the jack (B), and
turn the wrench clockwise to raise the jack head
approximately 3 inches (7.6 cm).
5-77

5. Raise the vehicle by turning the folding wrench
clockwise in the jack. Raise the vehicle far enough
off the ground so there is enough room for the
compact spare tire to t under the wheel well.
6. Remove all the wheel nuts and take off the at tire.
{CAUTION:
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel nuts
become loose after a time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
the places where the wheel attaches to the
vehicle. In an emergency, you can use a cloth
or a paper towel to do this; but be sure to use
a scraper or wire brush later, if needed, to get
all the rust or dirt off.
5-78

9. Lower the vehicle by attaching the folding wheel
wrench to the jack and turning the wrench
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. SeeCapacities
and Specifications on page 5-102for wheel nut
torque specication.
Notice:Improperly tightened wheel nuts can lead
to brake pulsation and rotor damage. To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper
torque specication. SeeCapacities and
Specifications on page 5-102for the wheel nut
torque specication.

To release the spare tire from the secondary latch, do
the following:
1. Place the jack under the vehicle, ahead of the rear
bumper. Position the center lift point of the jack
under the center of the compact spare tire.
2. Turn the folding wrench clockwise to raise the jack
until it lifts the secondary latch device under the
wheel plate.
3. Keep raising the jack until the compact spare tire
stops moving upward and is held rmly in place.
This lets you know that the secondary latch
has released.4. Lower the jack by turning the folding wrench
counterclockwise. Keep lowering the jack until
the compact spare tire is resting on the folding
wrench.
5. Grasp the compact spare tire with both hands and
pull it out from under the vehicle.
6. Reach under the vehicle and remove the folding
wrench and jack.
Have the hoist assembly inspected as soon as you can.
You will not be able to store a spare or at tire using
the hoist assembly until it has been repaired or replaced.

Headlamp Wiring
The headlamp wiring is protected by four internal fuses
in the underhood fuse block. 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
wiring checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by an internal
fuse in the underhood fuse block. 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, be sure to get it xed.
The rear washer pump is controlled by a relay located
in the engine compartment, behind the windshield
washer uid reservoir. The rear wiper motor is protected
by a fuse located in the instrument panel fuse block.
Power Windows and Other
Power Options
Circuit breakers in the instrument panel 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 xed.
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.
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 or use one of the spare fuses in the
underhood fuse block. 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 right
amperage. Replace it as soon as you can.
There are two fuse blocks in your vehicle, the instrument
panel fuse block and the underhood fuse block.
Instrument Panel Fuse Block
The instrument panel fuse block is located at the right
end of the instrument panel, on the passenger’s
side of the vehicle. Open the front passegner’s door,
and remove the cover, to access the fuse block.
Your vehicle may not have all of the fuses listed.
