{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.

dirt from the wheel
bolts, mounting
surfaces and
spare wheel.
{CAUTION:

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 398
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 398
for the wheel nut torque specication.11. Use the wheel wrench to tighten the nuts
firmly. Turn the wheel wrench clockwise

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 the vehicle if the cable
holding the spare tire is damaged. For the
secondary latch to work, the tire must be
stowed with the valve stem pointing down.
SeeStoring a Flat or Spare Tire and Tools on
page 380for instructions on storing the spare
tire correctly.
{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:
{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 the under spare.
1. Check under the vehicle to see if the cable
end is visible.
If the cable is not
visible, start this
procedure at Step 6.
377

2. Turn the wrench counterclockwise until
approximately 6 inches (15 cm) of cable
is exposed.
3. Connect the jack handle (A) and jack handle
extension (B) together and press the retention
clip (arrow) so it engages.4. Attach the jack handle/jack handle extension
to the jack. With the UP mark facing you,
slide the ratchet onto the end of the jack
handle extension.
378

5. Place the jack under the vehicle, ahead of the
rear bumper. Position the center lift point of
the jack under the center of the spare tire and
turn the handle clockwise to raise the jack
until it lifts the secondary latch spring.
6. Keep raising the jack until the spare tire stops
moving upward and is held firmly in place.
This lets you know that the secondary
latch has released. The spare tire is now
balancing on the jack.7. Lower the jack by turning the ratchet
counterclockwise. Keep lowering the jack
until the spare tire slides off the jack or
is hanging by the cable.
8. Disconnect the jack handle from the jack and
carefully remove the jack. Use one hand to
push against the spare while firmly pulling the
jack out from under the spare tire with the
other hand.
If the spare tire is hanging from the cable,
slide the ratchet onto the wheel wrench
and insert the wheel wrench into the hoist
shaft hole above the bumper. Turn the
wheel wrench counterclockwise to lower
the spare the rest of the way. Be sure the
DOWN mark on the ratchet is facing you.
379

9. Tilt the retainer at the end of the cable and
pull it through the wheel opening. Pull the
tire out from under the vehicle.
Notice:If you drive away before the spare tire
or secondary latch system cable has been
reinstalled, you could damage your vehicle.
Always reinstall this cable before driving
your vehicle.
10. If the cable is hanging under the vehicle,
turn the wheel wrench in the hoist shaft
hole in the bumper clockwise to raise the
cable back up.
Have the hoist assembly inspected as soon as
you can. You will not be able to store a spare or
flat tire using the hoist assembly until it has
been repaired or replaced.
