{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 430
for 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. See
Capacities and Specifications on page 430for
the wheel nut torque specication.
11. Tighten the wheel
nuts rmly in a
crisscross sequence
as shown by
turning the wheel
wrench clockwise.When you reinstall the regular wheel and tire, you
must also reinstall the center cap. Place the
cap on the wheel and tap it into place until it seats
ush with the wheel. The cap only goes on one
way. Be sure to line up the tab on the center cap
with the indentation on the wheel.

Secondary Latch System
Your vehicle has an underbody-mounted tire hoist
assembly that has a secondary latch system. It
is designed to stop the spare tire from suddenly
falling off your vehicle. For the secondary latch to
work, the spare must be installed with the valve
stem pointing down. SeeStoring a Flat or
Spare Tire and Tools on page 410.
{CAUTION:
Before beginning this procedure read all
the instructions. Failure to read and follow
the instructions could damage the hoist
assembly and you and others could get
hurt. Read and follow the instructions
listed next.To release the spare tire from the secondary latch,
do the following:
1. Check under the
vehicle to see if the
cable end tting
is visible.
2. If the cable end tting is not visible, proceed
to Step 6.
If it is visible, rst try to tighten the cable by
turning the wheel wrench clockwise until
you hear two clicks or feel it skip twice. You
cannot overtighten the cable.
3. Loosen the cable by turning the wheel wrench
counterclockwise three or four turns.

4. Repeat this procedure at least two times. If
the spare tire lowers to the ground, continue
with Step 5 underRemoving the Spare
Tire and Tools on page 395.
5. Turn the wrench counterclockwise until
approximately 6 inches (15 cm) of cable
is exposed.
6. Stand the wheel blocks on their shortest ends,
with the backs facing each other.
7. Place the bottom
edge of the jack (A)
on the wheel
blocks (B),
separating them so
that the jack is
balanced securely.8. Attach the jack handle, extension, and wheel
wrench to the jack and place it (with the
wheel blocks) under the vehicle towards the
front of the rear bumper. Position the center lift
point of the jack under the wheel.
9. Turn the wheel wrench clockwise to raise the
jack until it lifts the tire.
10. Continue raising the jack until the tire stops
moving upward and is held rmly in place,
the secondary latch has released, and the tire
is balancing on the jack.

11. Remove the jack handle and insert the hoist
end of the extension through the hole in the
rear bumper.
Turn the wheel wrench counterclockwise one
turn or until the wheel retainer assembly is
disengaged.12. Reinsert the jack handle into the jack.
Lower the jack by turning the wheel wrench
counterclockwise. Keep lowering the jack until
the spare tire slides off the jack or is hanging by
the cable.
{CAUTION:
Someone standing too close during the
procedure could be injured by the jack. If
the spare tire does not slide off the jack
completely, make sure no one is behind
you or on either side of you as you pull
the jack out from the under spare.

13. Disconnect the jack handle from the jack and
carefully remove the jack. Use one hand to
push against the spare while rmly pulling the
jack out from under the spare tire with the
other hand.
If the spare tire is hanging from the cable, insert
the hoist end of the extension into the hoist
shaft hole in the bumper and turn the wheel
wrench counterclockwise to lower the spare the
rest of the way.
14. Tilt the tire retainer at the end of the cable
and pull it through the wheel opening. Pull
the tire out from under the vehicle.
15. If the cable is hanging under the vehicle, turn
the wheel wrench clockwise to raise the cable.
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 replaced.
To continue changing the at tire, seeRemoving
the Flat Tire and Installing the Spare Tire on
page 398.

Spare Tire
Compact Spare Tire
Your vehicle may have a compact spare tire.
Although the compact spare tire was fully inated
when your vehicle was new, it can lose air over
time. Check the ination pressure regularly. It
should be 60 psi (420 kPa).
Notice:If your vehicle has four-wheel drive
and the compact spare tire is installed on your
vehicle, do not drive in four-wheel drive until
you can have your at tire repaired and/orreplaced. You could damage your vehicle, and
the repair costs would not be covered by your
warranty. Never use four-wheel drive when the
compact spare tire is installed on your vehicle.
After installing the compact spare on your vehicle,
you should stop as soon as possible and make sure
your vehicle’s spare tire is correctly inated. The
compact spare is made to perform well at speeds
up to 62 mph (100 km/h) for distances up to
500 miles (804 km).For heavy payloads or towing,
and for low traction or four-wheel-drive conditions,
repair or replace the full-size tire. Of course, it is
best to replace your vehicle’s spare with a full-size
tire as soon as you can. The spare tire will last
longer and be in good shape in case you need it
again.
Notice:When the compact spare is installed,
do not take your vehicle through an automatic
car wash with guide rails. The compact
spare can get caught on the rails. That can
damage the tire and wheel, and maybe
other parts of your vehicle.
Do not use your compact spare on other vehicles.

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 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.
Engine Compartment Fuse Block
The engine compartment fuse block is located on
the driver’s side of the engine compartment.
SeeEngine Compartment Overview on page 324
for more information on location.
To remove the cover, push in on the tab on the
end of the cover and lift. To reinstall the cover, line
up the tab and push down on the cover until the
tab clicks into place.
