handle extensions (I) as shown.3. Insert the hoist end
(open end) (F) of the
extension through
the hole (G) in the

3. Position the jack under the vehicle.
Front Tire Flat:If the ¯at tire is on a front tire of
the vehicle, you'll 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'll 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.

6. After mounting the spare,
put the wheel nuts back
on with the rounded
end of the nuts toward
the wheel. Tighten
each wheel nut by hand.
Then use the wheel
wrench to tighten
the wheel nuts until the
wheel is held against
the hub.
7. Turn the wheel wrench counterclockwise to lower
the vehicle. Lower the jack completely.
8. Tighten the nuts ®rmly in
a crisscross sequence as
shown by turning the
wheel wrench clockwise.
{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 speci®cation. See ªCapacities
and Speci®cationsº in the Index 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 ªCapacities and Speci®cationsº in
the index for the wheel nut torque speci®cation.
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.

always be stored under the vehicle with the
hoist. However, storing it that way for an extended
period of time could damage the wheel. To avoid
this, always stow the wheel properly with the valve
stem pointing down and have the wheel repaired
as soon as possible.Store the tire under the rear of the vehicle in the spare tire
carrier. Use the art and text following to help you:
