If the spare tire does not lower to
the ground, the secondary latch
is engaged causing the tire not
to lower. SeeSecondary Latch
System on page 10‑81.
4. When the tire has been lowered, pull the tire toward you
so you can reach the tire
retainer and pull it up through
the wheel opening.
If you have a vehicle which was
completed from a cab and
chassis, refer to the information
from body supplier/installer. The spare tire is a full‐size tire,
like the other tires on the
vehicle.
5. Put the spare tire near the flat tire.
Removing the Flat Tire and
Installing the Spare Tire
If the vehicle has plastic wheel nut
caps, loosen them by turning the
wheel wrench counterclockwise.
The wheel nut caps are designed to
remain with the center cap. Remove
the center cap.
If the wheel has a smooth center
piece, place the chisel end of the
wheel wrench in the slot on the
wheel and gently pry it out.
1. Do a safety check beforeproceeding. See If a Tire Goes
Flat on page 10‑71 for more
information.
2. Loosen all the wheel nuts with the wheel wrench. Do not
remove them yet. 3. Assemble the jack and tools:
Front Flat:
Assemble the
jack (A) together with the jack
handle (B), one or two jack
handle extensions (D) and the
wheel wrench (E).
Rear Flat: Assemble the jack (A)
together with the jack handle (B),
two jack handle extensions (D),
and the wheel wrench (E).

{WARNING
Raising the 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 fit the jack lift
head into the proper location
before raising the vehicle.
5. Raise the vehicle by turning the wheel wrench clockwise. Raise
the vehicle far enough off the
ground so there is enough room
for the spare tire to fit.
6. Remove all the wheel nuts.
7. Take flat tire off of the mountingsurface.
{WARNING
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make 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 places where the
(Continued)
WARNING (Continued)
wheel attaches to the vehicle. In
an emergency, a cloth or a paper
towel can be used; however, use
a scraper or wire brush later to
remove all rust or dirt.
8. Remove any rust or dirt from thewheel bolts, mounting surfaces
and spare wheel.

{WARNING
Never use oil or grease on bolts
or nuts because the nuts might
come loose. The vehicle's wheel
could fall off, causing a crash.
9. Put the wheel nuts back on withthe rounded end of the nuts
toward the wheel. Tighten each
wheel nut by hand until the
wheel is held against the hub. 10. Lower the vehicle by turning
the jack handle
counterclockwise. Lower the
jack completely.
{WARNING
Wheel nuts that are not tight can
work loose. If all the nuts on a
wheel come off, the wheel can
come off the vehicle, causing a
crash. All wheel nuts must be
properly tightened. Follow the
rules in this section to be sure
they are.
{WARNING
If wheel studs are damaged, they
can break. If all the studs on a
wheel broke, the wheel could
come off and cause a crash.
If any stud is damaged because
of a loose-running wheel, it could
be that all of the studs are
damaged. To be sure, replace all
studs on the wheel. If the stud
holes in a wheel have become
larger, the wheel could collapse in
operation. Replace any wheel if
its stud holes have become larger
or distorted in any way. Inspect
hubs and hub‐piloted wheels for
damage. Because of loose
running wheels, piloting pad
damage may occur and require
replacement of the entire hub, for
proper centering of the wheels.
When replacing studs, hubs,
wheel nuts or wheels, be sure to
use GM original equipment parts.

{WARNING
Wheel nuts that are improperly or
incorrectly tightened can cause
the wheels to become loose or
come off. The wheel nuts should
be tightened with a torque wrench
to the proper torque specification
after replacing. Follow the torque
specification supplied by the
aftermarket manufacturer when
using accessory locking wheel
nuts. SeeCapacities and
Specifications on page 12‑2 for
original equipment wheel nut
torque specifications.
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 specification. See
Capacities and Specifications on
page 12‑2 for the wheel nut
torque specification.
11. Use the wheel wrench to tighten the nuts firmly. Turn the
wheel wrench clockwise and in
a crisscross sequence as
shown. 12. Put the wheel cover or the
center cap and plastic wheel
nut caps back on. Remove any
wheel blocks.
Have a technician check the
wheel nut tightness of all
wheels with a torque wrench
after the first 160 km
(100 miles) and then 1600 km
(1,000 miles) after that. Repeat
this service whenever you have
a tire removed or serviced. See
Capacities and Specifications
on page 12‑2 for more
information.

Secondary Latch System
This 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.
See“Storing a Flat or Spare Tire
and Tools” underTire Changing on
page 10‑73 for instructions on
storing the spare tire correctly.{WARNING
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:
{WARNING
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.
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.
2. Turn the hoist extension counterclockwise until
approximately 15 cm (6 in) of
cable is exposed.

3. Attach the jack handle/jackhandle extension and wheel
wrench to the jack.
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 and turn the handle
clockwise to raise the jack until it
lifts the secondary latch spring.
5. 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. 6. 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.
7. 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, assembly the wheel
wrench onto the hoist extension
and insert the chisel end of the
hoist extension into the hoist
shaft hole above the bumper.
Turn the wheel wrench
counterclockwise to lower the
spare the rest of the way.
8. Tilt the retainer at the end of the cable and pull it through the
wheel opening. Pull the tire out
from under the vehicle.

Vehicle Care 10-83
Notice:If you drive away before
the spare tire or secondary
latch system cable has been
reinstalled, you could damage the
vehicle. Always reinstall this
cable before driving the vehicle.
9. 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.
To continue changing the flat tire,
return to Step 4 of “Storing a Flat or
Spare Tire and Tools” underTire
Changing on page 10‑73.Full-Size Spare Tire
This vehicle, when new, may have
had a fully-inflated spare tire.
A spare tire may lose air over time,
so check its inflation pressure
regularly. See Tire Pressure on
page 10‑57 andVehicle Load Limits
on page 9‑12 for information
regarding proper tire inflation and
loading the vehicle. For instruction
on how to remove, install or store a
spare tire, see “Removing the Flat
Tire and Installing the Spare Tire”
and “Storing a Flat or Spare Tire
and Tools” underTire Changing on
page 10‑73. After installing the spare tire on the
vehicle, you should stop as soon as
possible and make sure the spare is
correctly inflated. The spare tire is
made to perform well at speeds
up to 112 km/h (70 mph) at the
recommended inflation pressure, so
you can finish your trip.
Have the damaged or flat road tire
repaired or replaced as soon as you
can and installed back onto the
vehicle. This way, a spare tire will
be available in case you need it
again. Do not mix tires and wheels
of different sizes, because they will
not fit. Keep the spare tire and its
wheel together.
