3. Position the jack under the vehicle as shown.
Front Tire Flat:If the at tire is on a front tire of
the vehicle, you will need to use the jack handle (C)
and only one jack handle extension (D). Attach
the wheel wrench to the jack handle extension.
Attach the jack handle to the jack. Position the jack
on the frame behind the at tire where the frame
sections overlap. Turn the wheel wrench clockwise
to raise the vehicle. Raise the vehicle far enough
off the ground so there is enough room for the spare
tire to clear the ground.Rear Tire Flat:If the at tire is on a rear tire of the
vehicle, you will need to use the jack handle (C)
and both jack handle extensions (D). Attach
the wheel wrench to the jack handle extensions.
Attach the jack handle to the jack. Use the jacking
pad provided on the rear axle. Turn the wheel
wrench clockwise to raise the vehicle. Raise the
vehicle far enough off the ground so there is
enough room for the spare tire to clear the ground. Front Position

4. 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. Remove any rust or dirt
from the wheel bolts,
mounting surfaces
and spare wheel.
{CAUTION:
Never use oil or grease on studs or nuts.
If you do, the nuts might come loose. Your
wheel could fall off, causing a serious
accident.
5-88

6. Put the wheel nuts back
on with the rounded
end of the nuts toward
the wheel after
mounting the spare.
7. Tighten each wheel nut by hand. Then use the
wheel wrench to tighten the nuts until the wheel
is held against the hub.
8. Turn the wheel wrench counterclockwise to lower
the vehicle. 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 5-118for wheel
nut torque specication.
5-89

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 5-118for the wheel nut
torque specication.
9. Tighten the 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 either the center cap, or bolt-on
hub cap, depending on what your vehicle is equipped
with. For center caps, 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.
For bolt-on hub caps, align the plastic nut caps with
the wheel nuts and then tighten by hand. Then use the
wheel wrench to tighten.
Secondary Latch System
Your vehicle has an underbody-mounted tire hoist
assembly equipped with 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 5-94.
{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 below.
5-90

To release the spare tire from the secondary latch,
do the following:
1. Check under the
vehicle to see if the
cable end is visible.
If the cable is not
visible proceed
to Step 6.
2. 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 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 ofRemoving the Spare Tire and Tools
on page 5-80.5. If the spare does not lower, 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.
5-91

8. Attach the jack handle, extension, and wheel
wrench to the jack and place it (with the wheel
blocks) under the vehicle toward the front of the
rear bumper.9. Position the center lift point of the jack under the
center of the spare tire.
10. Turn the wrench clockwise to raise the jack until it
lifts the end tting.
11. Continue raising the jack until the spare tire stops
moving upward and is held rmly in place. The
secondary latch has released and the spare tire is
balancing on the jack.
12. 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.
5-92

{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 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 extension, and wheel wrench 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 (G)
at the end of the cable
and pull it through
the wheel opening.
Pull the tire out
from under the vehicle.
15. Turn the wheel wrench in the hoist shaft hole in the
bumper clockwise to raise the cable back up if the
cable is hanging under the vehicle.
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 5-84.
