Removing the Flat Tire and
Installing the Spare Tire
To remove the at tire and install the spare, do the
following:
1. Loosen the wheel nuts, but do not remove them
yet, using the wheel wrench. Turn the handle
about 180 degrees, then ip the handle back to the
starting position. This avoids taking the wrench
off the lug nut for each turn.2. Find the jacking
location using the
hoisting notches
located in the plastic
molding. The notches
in the plastic molding
are marked with a
triangle shape to help
you nd them.
3. Attach the wheel wrench to the jack.
{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.
5-74

{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 t the
jack lift head into the proper location before
raising the vehicle.
{CAUTION:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous without
the appropriate safety equipment and training.
The jack provided with your vehicle is
designed only for changing a at tire. If it is
used for anything else, you or others could be
badly injured or killed if the vehicle slips off
the jack. Use the jack provided with your
vehicle only for changing a at tire.4. Turn the wheel wrench clockwise to raise the jack
lift head until the jack just ts under the vehicle.
5. Raise the jack by turning the wheel wrench
clockwise until the slots in the jack head t into the
metal ange located behind the triangle on the
plastic molding as shown.
Notice:Using a jack to raise the vehicle without
positioning it correctly could damage your vehicle.
When raising your vehicle on a jack, be sure to
position it correctly under the frame and avoid
contact with the plastic molding.
6. Put the compact spare tire near you.
5-75

7. Raise the vehicle by turning the wheel wrench
clockwise. Raise the vehicle far enough off the
ground for the compact spare tire to t under the
vehicle.8. Remove all the wheel
nuts and take off the
at tire.{CAUTION:
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel nuts
become loose after a time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
the places where the wheel attaches to the
vehicle. In an emergency, you can use a cloth
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.

{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.
9. Remove any rust or dirt
from the wheel bolts,
mounting surfaces
and spare wheel.
10. Install the spare tire.
11. Put the wheel nuts back on with the rounded end of
the nuts toward the wheel.

against the hub.13. Lower the vehicle by attaching the wheel wrench to
the jack and turning the wrench counterclockwise.
Lower the jack completely.
5-77

{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. SeeCapacities
and Specifications on page 5-103for 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.14. Tighten the wheel nuts
rmly in a crisscross
sequence, as shown.
Notice:Wheel covers will not t on your compact
spare. If you try to put a wheel cover on the compact
spare, you could damage the cover or the spare.
Do not try to put a wheel cover on the compact
spare tire. It will not t. Store the wheel cover securely
in the rear of the vehicle until you have the at tire
repaired or replaced.

Secondary Latch System
Your vehicle has an underbody mounted tire hoist
assembly equipped with a secondary latch system. It is
designed to stop the compact spare tire from suddenly
falling off your 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 5-81
for 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.
{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 spare.
To release the spare tire from the secondary latch, do
the following:
1. If the cable is not visible, start this procedure at
Step 3.
2. If the cable is visible,
turn the wrench
counterclockwise until
approximately 6 inches
(15 cm) of cable is
exposed.
5-79

3. Attach the wheel wrench to the jack and raise the
jack at least 10 turns.
4. 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.
5. Turn the wheel wrench 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 rmly in place, this lets
you know that the secondary latch has released.
7. Lower the jack by turning the wheel wrench
counterclockwise. Keep lowering the jack until
the spare tire is resting on the wheel wrench.8. Grasp the spare tire with both hands and pull it out
from under the vehicle.
9. Reach under the vehicle and remove the wheel
wrench and jack.
10. Tilt the retainer and slip it through the wheel
opening when the spare tire has been completely
lowered.
11. Turn the wrench clockwise to raise the cable back
up if the cable is hanging.
Have the hoist assembly inspected as soon as you can.
