such as troughs or ruts, is normal. If the
vehicle is vibrating when driving on a
smooth road, the tires and wheels may
need to be rebalanced. See your dealer for
proper diagnosis.
Wheel Replacement
Replace any wheel that is bent, cracked,
or badly rusted or corroded. If wheel nuts
keep coming loose, the wheel, wheel bolts,
and wheel nuts should be replaced. If the
wheel leaks air, replace it. Some aluminum
wheels can be repaired. See your dealer if
any of these conditions exist.
Your dealer will know the kind of wheel that
is needed.
Each new wheel should have the same
load-carrying capacity, diameter, width,
offset, and be mounted the same way as
the one it replaces.
Replace wheels, wheel bolts, wheel nuts,
or Tire Pressure Monitor System (TPMS)
sensors with new GM original equipment
parts.
{Warning
Using the wrong replacement wheels,
wheel bolts, or wheel nuts can be
dangerous. It could affect the braking and
handling of the vehicle. Tires can lose air
and cause loss of control, resulting in a
crash. Always use the correct wheel,
wheel bolts, and wheel nuts for
replacement.
{Warning
Replacing a wheel with a used one is
dangerous. How it has been used or how
far it has been driven may be unknown.
It could fail suddenly and cause a crash.
When replacing wheels, use a new GM
original equipment wheel.
Caution
The wrong wheel can also cause
problems with bearing life, brake cooling,
speedometer or odometer calibration,
headlamp aim, bumper height, vehicle
ground clearance, and tire or tire chain
clearance to the body and chassis.
Tire Chains
{Warning
If the vehicle has 235/55R20, 245/65R17,
or 255/65R17 size tires, do not use tire
chains. There is not enough clearance.
Tire chains used on a vehicle without the
proper amount of clearance can cause
damage to the brakes, suspension,
or other vehicle parts. The area damaged
by the tire chains could cause loss of
control and a crash. Use another type of
traction device only if its manufacturer
recommends it for the vehicle's tire size
combination and road conditions. Follow
that manufacturer's instructions. To avoid
vehicle damage, drive slow and readjust
or remove the traction device if it
contacts the vehicle. Do not spin the
wheels. If traction devices are used,
install them on the front tires.
Caution
If the vehicle is equipped with a tire size
other than 235/55R20, 245/65R17, or 255/
65R17 use tire chains only where legal

Caution (Continued)
and only when necessary. Use low profile
chains that add no more than 12 mm
thickness to the tire tread and inner
sidewall. Use chains that are the proper
size for the tires. Install them on the tires
of the front axle. Do not use chains on
the tires of the rear axle. Tighten them
as tightly as possible with the ends
securely fastened. Drive slowly and follow
the chain manufacturer's instructions.
If the chains contact the vehicle, stop and
retighten them. If the contact continues,
slow down until it stops. Driving too fast
or spinning the wheels with chains on
will damage the vehicle.
If a Tire Goes Flat
It is unusual for a tire to blow out while
driving, especially if the tires are maintained
properly. SeeTires0293. If air goes out of
a tire, it is much more likely to leak out
slowly. But if there is ever a blowout, here
are a few tips about what to expect and
what to do: If a front tire fails, the flat tire creates a
drag that pulls the vehicle toward that side.
Take your foot off the accelerator pedal and
grip the steering wheel firmly. Steer to
maintain lane position, and then gently
brake to a stop, well off the road,
if possible.
A rear blowout, particularly on a curve, acts
much like a skid and may require the same
correction as used in a skid. Stop pressing
the accelerator pedal and steer to straighten
the vehicle. It may be very bumpy and
noisy. Gently brake to a stop, well off the
road, if possible.
{Warning
Driving on a flat tire will cause
permanent damage to the tire.
Re-inflating a tire after it has been driven
on while severely underinflated or flat
may cause a blowout and a serious crash.
Never attempt to re-inflate a tire that has
been driven on while severely
underinflated or flat. Have your dealer or
an authorized tire service center repair or
replace the flat tire as soon as possible.
{Warning
Lifting a vehicle and getting under it to
do maintenance or repairs is dangerous
without the appropriate safety equipment
and training. If a jack is provided with
the vehicle, it is designed only for
changing a flat tire. If it is used for
anything else, you or others could be
badly injured or killed if the vehicle slips
off the jack. If a jack is provided with the
vehicle, only use it for changing a
flat tire.
If a tire goes flat, avoid further tire and
wheel damage by driving slowly to a level
place, well off the road, if possible. Turn on
the hazard warning flashers. See Hazard
Warning Flashers 0131.
If your vehicle is loaded at or near
maximum cargo capacity, it may be difficult
to fit the jack under the vehicle due to the
environment (shoulder slope, road debris,
etc.). Removal of some weight may improve
the ability to fit the jack under the vehicle
at the correct jacking location.

10. Remove any rust or dirt from the wheelbolts, mounting surfaces, and spare
wheel.
11. Place the compact spare tire on the wheel-mounting surface.
{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.
12. Reinstall the wheel nuts. Tighten each nut by hand until the wheel is held
against the hub.
13. Lower the vehicle by turning the jack handle counterclockwise.
{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. See
Capacities and Specifications0348 for
original equipment wheel nut torque
specifications.
Caution
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 0348 for the wheel nut
torque specification.
14. Tighten the wheel nuts firmly in a crisscross sequence, as shown.
15. Lower the jack all the way and remove the jack from under the vehicle.
16. Tighten the wheel nuts firmly with the wheel wrench.
When reinstalling the wheel cover or center
cap on the full-size tire, tighten all six plastic
caps hand snug with the aid of the wheel
wrench and tighten them with the wheel
wrench an additional one-quarter of a turn.

5. Hook the cable onto the outside portionof the liftgate hinges.
6. Hook the other end of the cable onto the outside portion of the liftgate hinge
on the other side of the vehicle.
7. Pull on the cable to make sure it is secure.8. Make sure the metal tube is centered atthe striker. Push the tube toward the
front of the vehicle.
9. Close the liftgate and make sure it is fully latched.
The compact spare is for temporary use
only. Replace the compact spare tire with a
full-size tire as soon as you can.
Storing the Compact Spare Tire and
Tools
To store the spare tire and tools: 1. Open the liftgate. See Liftgate018.
2. Lift the load floor.
3. Remove the cargo management system. 4. Put back the spare tire and all tools as
they were stored in the rear storage
compartment.
5. Install the cargo management system and load floor.
The compact spare is for temporary use
only. Replace the compact spare tire with a
full-size tire as soon as you can.
Compact Spare Tire
{Warning
Driving with more than one compact
spare tire at a time could result in loss of
braking and handling. This could lead to a
crash and you or others could be injured.
Use only one compact spare tire at
a time.
If this vehicle has a compact spare tire, it
was fully inflated when new; however, it
can lose air over time. Check the inflation
pressure regularly. It should be 420 kPa
(60 psi).
Stop as soon as possible and check that the
spare tire is correctly inflated after being
installed on the vehicle. The compact spare
tire is designed for temporary use only. The
