{CAUTION:
Rust or dirt on the wheel, or on the parts
to which it is fastened, can make the
wheel nuts become loose after time. The
wheel could come off and cause an
accident. When changing a wheel, remove
any rust or dirt from the places where the
wheel attaches to the vehicle. In an
emergency, a cloth or a paper towel can
be used to do this; but be sure to use a
scraper or wire brush later, if needed, to
get all the rust or dirt off.
{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.10. Remove any rust or

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 speci cation. See
Capacities and Specifications on page 483
for wheel nut torque speci cation.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 speci cation. See

Storing a Flat or Spare Tire
and Tools
Storing the Spare Tire
{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 will not 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.
{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.
To store the spare tire:
1. Lay the compact spare tire near the rear of
the vehicle with the valve stem down.
2. Reinstall the plastic spare tire heat shield on
the compact spare tire.
3. If the vehicle has aluminum wheels, remove
the small center cap by tapping the back of
the cap with the extension of the shaft.

4. Slide the cable retainer through the center of
the wheel and start to raise the compact
spare tire.
Make sure the retainer is fully seated across
the underside of the wheel.
5. When the compact spare tire is almost in the
stored position, turn the tire so the valve is
toward the rear of the vehicle.
This position helps when checking the air
pressure in the compact spare tire.
6. Raise the tire fully against the underside of
the vehicle. Continue turning the lug 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.
7. Make sure the tire is stored securely. Push,
pull (A), and then try to turn (B) the tire. If the
tire moves, use the lug wrench to tighten
the cable.

Storing the Flat Tire
Notice:Storing the full-size at tire in the
underbody hoist system can expose it to heat
from the exhaust system. This can damage
the tire and underbody hoist system. Do
not store the full-size at tire in the underbody
hoist system.
1. Remove the cable package from the jack
storage area.
2. Remove the small center cap by tapping the
back of the cap with the extension of the
shaft, if the vehicle has aluminum wheels.
3. Put the at tire in the rear storage area with
the valve stem pointing toward the rear of the
vehicle.4. Hook on end of the cable onto the outside
portion of the liftgate hinge opposite (B).
5. Pull the cable (A) through the door striker (E),
the center of the wheel (D), and the plastic
spare tire heat shield (C), as shown.

Put back all tools as they were stored in the jack
storage compartment and put the compartment
cover back on.
1. Make that the bottom of the jack is facing
toward you.
2. Turn the jack (C) on its side and place it down
on the holding bracket.
3. Reinstall the wing bolt (B) by turning it
clockwise.
4. To replace the cover, line up the tabs on the
bottom of the cover with the slots in the cover
opening. Push the cover in place, insuring
that the upper front and rear tabs are in
the opening and push the cover closed. Make
sure that the center latch is fully engaged.
This secures the cover in place.
Store the center cap or the plastic bolt-on wheel
covers until a full size tire is put back on the
vehicle. When you replace the compact spare with
a full-size tire, reinstall the bolt-on wheel covers
or the center cap. Hand-tighten them over
the wheel nuts, using the lug wrench.Compact Spare Tire
Although the compact spare tire was fully in ated
when the vehicle was new, it can lose air after
a time. Check the in ation pressure regularly. It
should be 60 psi (420 kPa).
After installing the compact spare on the vehicle,
stop as soon as possible and make sure the
spare tire is correctly in ated. 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
the full-size tire repaired or replaced at your
convenience. Of course, it is best to replace the
spare with a full-size tire as soon as possible. The
spare tire will last longer and be in good shape
in case it is needed 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 the compact spare on other vehicles.
