the secondary latch is engaged causing
the tire not to lower. SeeSecondary Latch
System on page 543for more information.6. Use the wheel
wrench hook that
allows you to
pull the hoist cable
towards you, to
assist in reaching
the spare tire.

retainer (G) at the
end of the cable
when the tire
has been lowered,

Removing the Flat Tire and
Installing the Spare Tire
Use the following pictures and instructions to
remove the at tire and raise the vehicle.
1. Remove the center cap, if your vehicle has
one, by placing the chisel end of the wheel
wrench in the slot on the wheel and gently pry
the cap out.If the wheel has bolt-on wheel covers, loosen
the plastic nut caps by turning the wheel
wrench counterclockwise. If needed, nish
loosening them by hand. The nut caps will not
come off. Using the at end of the wheel
wrench, pry along the edge of the cover until
it comes off.

nuts. Turn the wheel wrench counterclockwise
to loosen the wheel nuts. Do not remove
the wheel nuts yet.

Front Tire Flat:If the at tire is on a front tire
of the vehicle, you will need to use the jack
handle and only one jack handle extension.

extension. Attach the jack handle to the
jack (A). Position the jack on the frame behind
the at tire where the frame sections overlap.Turn the wheel wrench clockwise to raise the

the wheel wrench to tighten the nuts until the
wheel is held against the hub.
9. 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. See
Capacities and Specifications on page 572
for wheel nut torque specication.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. See
Capacities and Specifications on page 572for
the wheel nut torque specication.
10. Tighten the nuts rmly in a crisscross
sequence as shown by turning the wheel
wrench clockwise.

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 wheel 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 533.
5. If the spare tire does not lower, turn the wheel
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.

11. Continue raising the jack until the spare tire
stops moving upward and is held rmly in
place so that 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.
{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 under the spare.13. Disconnect the jack handle from the jack and
carefully remove the jack with the other hand.
14. 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 the extension, and wheel wrench into
the hoist shaft hole in the bumper and
turn the wheel wrench counterclockwise to
lower the spare tire the rest of the way.
