If the spare tire will not lower, the secondary latch may
be engaged causing the tire not to lower. Do the
following to check the cable:
1. Check under the vehicle to see if the cable is
visible.
2. If it’s not visible, see “Secondary Latch System”
following.
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 over-tighten
the cable.
3. Then loosen the cable by turning the wrench
counterclockwise three or four turns.
4. If the spare tire has not lowered, tighten the cable
all the way and then loosen it at least two times.
If the spare tire did lower to the ground, continue
with Step 4 under “Removing the Spare Tire” earlier
in this section.
5. If you still cannot lower the spare tire to the ground,
see “Secondary Latch System” following.Secondary Latch System
Your vehicle has an underbody mounted tire hoist
assembly equipped with a secondary latch system. It’s
designed to stop the compact spare tire from suddenly
falling off your vehicle if the cable holding the spare
tire is damaged. For the secondary latch to work, the tire
must be stowed with the valve stem pointing down.
See “Storing the Spare Tire and Tools” later in
this section for instructions on storing the spare tire
correctly.
{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.
To release the spare tire from the secondary latch, do
the following:

{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.
1. If the cable is not visible, start this procedure
at Step 3.
2. Turn the wrench counterclockwise until
approximately 6 inches (15 cm) of cable is exposed.
3. Attach the wheel wrench to the jack and raise the
jack at least 10 turns.

Removing the Flat Tire and Installing
the Spare Tire
1. Using the at end of the wheel wrench, pry off the
center cap at the notch. Be careful; the edges may
be sharp. Don’t try to remove the cover with
your bare hands.
2. Loosen the wheel nuts - but do not remove
them - using the wheel wrench. (Turn the handle
about 180 degrees, then ip the handle back to the
starting position. This avoids taking the wrench
off the lug nut for each turn.)
3. Find the jacking
location using the
hoisting notches
located in the plastic
molding. The notches
in the plastic molding
are marked with a
triangle shape to help
you nd them.

6. Raise the jack by turning the wheel wrench
clockwise until the slots in the jack head t into the
metal ange located behind the triangle on the
plastic molding as shown.Notice:Using a jack to raise the vehicle without
positioning it correctly could damage your vehicle.
When raising your vehicle on a jack, be sure to
position it correctly under the frame and avoid
contact with the plastic molding.
7. Put the compact spare tire near you.
8. Raise the vehicle by turning the wheel wrench
clockwise. Raise the vehicle far enough off the
ground for the compact spare tire to t under the
vehicle.
9. Remove all the wheel nuts and take off the at tire.
5-86

10. Remove any rust or dirt
from the wheel bolts,
mounting surfaces
and spare wheel.
{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 you need to, to
get all the rust or dirt off.
{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.
11. Install the spare tire and put the wheel nuts back on
with the rounded end of the nuts toward the wheel.
Tighten each nut by hand until the wheel is held
against the hub.
12. Lower the vehicle by attaching the wheel wrench to
the jack and turning the wrench counterclockwise.
Lower the jack completely.
5-87

13. Tighten the wheel nuts
rmly in a crisscross
sequence, as shown.
{CAUTION:
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to become
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
100 lb-ft (140Y).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.
14. Don’t try to put a wheel cover on the compact spare
tire. It won’t t. Store the wheel cover securely in
the rear of the vehicle until you have the at
tire repaired or replaced.
Notice:Wheel covers will not t on your compact
spare. If you try to put a wheel cover on the compact
spare, you could damage the cover or the spare.

Storing the Spare Tire and Tools
{CAUTION:
Storing a jack, a tire, or other equipment in the
passenger compartment of the vehicle could
cause injury. In a sudden stop or collision,
loose equipment could strike someone. Store
all these in the proper place.
{CAUTION:
The underbody-mounted spare tire needs to be
stored with the valve stem pointing down.
If the spare tire is stored with the valve stem
pointing upwards, its secondary latch won’t
CAUTION: (Continued)
CAUTION: (Continued)
work properly and the spare tire could loosen
and suddenly fall from your vehicle. If this
happened when your vehicle was being
driven, the tire might contact a person or
another vehicle, causing injury and, of course,
damage to itself as well. Be sure the
underbody-mounted spare tire is stored with
its valve stem pointing down.
1. Lay the compact spare tire on the ground at the
rear of the vehicle. Position the compact spare
tire so that the valve stem is pointed down facing
the rear of the vehicle.
2. Lower the cable to the ground. See “Removing the
Spare Tire” earlier in this section.
5-91

3. Tilt the retainer downward and slip it through the
center hole of the spare tire.
Make sure the retainer is fully seated across the
underside of the wheel.
4. Attach the wheel wrench to the hoist shaft.
5. Turn the wheel wrench clockwise to lift the
spare tire.
6. When the tire is almost in the stored position, turn
the tire so that the valve stem is towards the rear of
the vehicle.
This will help when you check and maintain tire
pressure in the spare.
7. Raise the tire fully against the underside of the
vehicle. Continue turning the wheel wrench until
you feel more than two clicks. This indicates that the
compact spare tire is secure and the cable is
tight. The spare tire hoist cannot be overtightened.
8. Make sure the tire is stored securely. Push, pull (A),
and then try to rotate or turn the tire (B). If the tire
moves, use the wheel wrench to tighten the
cable.
Put back all tools as they were stored in the rear
storage compartment and put the compartment cover
back on.

Compact Spare Tire
Although the compact spare tire was fully inated when
your vehicle was new, it can lose air after a time.
Check the ination pressure regularly. It should be
60 psi (420 kPa).
After installing the compact spare on your vehicle, you
should stop as soon as possible and make sure
your spare tire is correctly inated. The compact spare
is made to perform well at speeds up to 65 mph
(105 km/h) for distances up to 3,000 miles (5 000 km),
so you can nish your trip and have your full-size
tire repaired or replaced where you want. Of course, it’s
best to replace your spare with a full-size tire as
soon as you can. Your spare will last longer and be in
good shape in case you need it again.Notice:When the compact spare is installed, don’t
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.
Don’t use your compact spare on other vehicles.
And don’t mix your compact spare tire or wheel with
other wheels or tires. They won’t t. Keep your spare tire
and its wheel together.
Notice:Tire chains won’t t your compact spare.
Using them can damage your vehicle and can
damage the chains too. Don’t use tire chains on
your compact spare.
