5-24 Removing the Flat Tire and Installing the
Spare Tire
1. If your vehicle is equipped with wheel covers,
use the wheel wrench to begin loosening the
plastic wheel nut caps. Once you have loosened
the plastic wheel nut caps with the wheel wrench
you can finish loosening them with your fingers.
Using the flat end of the wheel wrench, pry along
the edge of the wheel cover until it comes off.
If your vehicle has alloy wheels, first remove
the decorative nut caps (if equipped) using the
wheel wrench.2. Then use the wheel wrench to loosen all the wheel
nuts. Don't remove them yet.3. Near each wheel well is a notch in the frame which the
jack head fits in. The front notch is 9 inches (23 cm)
back from the front wheel well. The rear notch is
8 inches (20 cm) forward from the rear wheel well.
As is shown in the diagram above, if your vehicle
has flared side moldings, both front and rear notches
are 18 inches (46 cm) from the wheel wells.
Position the jack and raise the jack head until it fits
firmly into the notch in the vehicle's frame nearest
the flat tire. Put the compact spare tire near you.

CAUTION:
Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack, you
could be badly injured or killed. Never get under
a vehicle when it is supported only by a jack.
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 fit the
jack lift head into the proper location before
raising the vehicle.4. Raise the vehicle by turning the jack handle
clockwise. Raise the vehicle far enough off the
ground so there is enough room for the compact
spare tire to fit underneath the wheel well.

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.
7. Place the compact spare tire on the
wheel
-mounting surface.
8. Reinstall the wheel nuts
with the rounded end
of the nuts toward the
wheel. Tighten each nut
by hand until the wheel
is held against the hub.
9. Lower the vehicle by turning the jack handle
counterclockwise. Lower the jack completely.

10. Tighten the wheel nuts
firmly 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 (140 N´m).
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 specification.
Don't try to put a wheel cover on your compact spare
tire. It won't fit. Store the wheel cover in the trunk
until you have the flat tire repaired or replaced.
NOTICE:
Wheel covers won't fit on your compact spare.
If you try to put a wheel cover on your compact
spare, you could damage the cover or the spare.
