or a paper towel to do this; but be sure to use
a scraper or wire brush later, if needed, to get
all the rust or dirt off.6. Remove any rust or dirt
from the wheel bolts,
mounting surfaces, and

{CAUTION:
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to come loose

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. SeeCapacities
and Specifications on page 5-122for 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. SeeCapacities and
Specifications on page 5-122for the wheel nut
torque specication.
11. Tighten the nuts rmly in a crisscross sequence as
shown by turning the wheel wrench clockwise.

When you reinstall the full-size wheel and tire, you must
also reinstall the wheel cover with attached plastic
nuts, the plastic nut caps, or the smooth center cap.
If you are reinstalling a wheel cover with attached
plastic nuts, place it on the wheel and tighten the
nuts by hand to get them started. Then tighten
the nut caps with the wheel wrench until they are
snug. Do not overtighten the nut caps or they
may break.
If you are reinstalling plastic nut caps, tighten the
nuts by hand to get them started. Then tighten
the nut caps with the wheel wrench until they are
snug. Do not overtighten the nut caps or they
may break.
If you are reinstalling the smooth center cap, place
it on the wheel and tap it into place until it seats
ush with the wheel.
Secondary Latch System
Your vehicle has an underbody-mounted tire hoist
assembly equipped with a secondary latch system. It is
designed to stop the spare tire from suddenly falling
off your vehicle. For the secondary latch to work,
the spare must be installed with the valve stem pointing
down. SeeStoring a Flat or Spare Tire and Tools on
page 5-100.
{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 next.

To release the spare tire from the secondary latch, do
the following:
1. Check under the vehicle to see if the cable end is
visible.
If the cable is not visible, proceed to Step 6.
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 5-86.
5. Turn the 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.

until it lifts the end tting.
11. Continue raising the jack until the spare tire stops
moving upward and is held rmly in place. The
secondary latch has released and the spare tire is
balancing on the jack.

counterclockwise. Keep lowering the jack until the
spare tire slides off the jack or is hanging by
the cable.

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.

hoist handle, extension and wheel wrench into
the hoist shaft hole in the bumper and turn
the wheel wrench counterclockwise to lower the
spare the rest of the way.15. Tilt the retainer at the
end of the cable and
pull it through the
wheel opening. Pull the
tire out from under
the vehicle.
