Compact Spare Tire Example
9-44 Vehicle Service and Care

Any time you notice unusual
wear, rotate the tires as soon
as possible and check wheel
alignment. Also check for
damaged tires or wheels.
SeeWhen It Is Time for New
Tires on page 9-59andWheel
Replacement on page 9-64.
When rotating the vehicle’s tires,
always use the correct rotation
pattern shown here.The compact spare tire, if the
vehicle has one, is not included
in the tire rotation.
After the tires have been rotated,
adjust the front and rear ination
pressures as shown on the Tire
and Loading Information label.
SeeInflation - Tire Pressure on
page 9-49andLoading the
Vehicle on page 8-30.
Reset the Tire Pressure Monitor
System. SeeTire Pressure
Monitor Operation on page 9-54.
Make certain that all wheel
nuts are properly tightened.
See “Wheel Nut Torque” under
Capacities and Specifications on
page 10-2.{CAUTION
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 you
change a wheel, remove any
rust or dirt from 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. SeeChanging
a Flat Tire on page 9-75.
9-58 Vehicle Service and Care

Wheel Alignment and
Tire Balance
The tires and wheels on your vehicle
were aligned and balanced carefully
at the factory to give you the longest
tire life and best overall performance.
Adjustments to wheel alignment and
tire balancing will not be necessary
on a regular basis. However, if you
notice unusual tire wear or your
vehicle pulling to one side or the
other, the alignment might need to be
checked. If you notice your vehicle
vibrating when driving on a smooth
road, the tires and wheels might
need to be rebalanced. See your
dealer/retailer 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 (except some
aluminum wheels, which can
sometimes be repaired). See your
dealer/retailer if any of these
conditions exist.
Your dealer/retailer will know the
kind of wheel you need.
Each new wheel should have
the same load-carrying capacity,
diameter, width, offset and be
mounted the same way as the
one it replaces.
If you need to replace any of the
wheels, wheel bolts or wheel
nuts, replace them only with new
GM original equipment parts.
This way, you will be sure to have
the right wheel, wheel bolts and
wheel nuts for the vehicle.{CAUTION
Using the wrong replacement
wheels, wheel bolts, or wheel nuts
on your vehicle can be dangerous.
It could affect the braking and
handling of your vehicle, make
your tires lose air and make you
lose control. You could have a
collision in which you or others
could be injured. Always use the
correct wheel, wheel bolts, and
wheel nuts for replacement.
Notice: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.
SeeChanging a Flat Tire on
page 9-75for more information.

Tire Changing
If a Tire Goes Flat
It is unusual for a tire to blowout
while you are driving, especially if
you maintain your tires properly. See
Tires on page 9-42. If air goes out of
a tire, It is much more likely to leak
out slowly. But if you should ever
have a blowout, here are a few tips
about what to expect and what to do:
If a front tire fails, the at tire will
create a drag that pulls the vehicle
toward that side. Take your foot off
the accelerator pedal and grip the
steering wheel rmly. Steer to
maintain lane position, and then
gently brake to a stop well out of the
traffic lane.A rear blowout, particularly on a
curve, acts much like a skid
and may require the same correction
you would use in a skid. In any
rear blowout, remove your foot from
the accelerator pedal. Get the
vehicle under control by steering the
way you want the vehicle to go. It
may be very bumpy and noisy,
but you can still steer. Gently brake
to a stop, well off the road if
possible.
If a tire goes at, and your vehicle
has a compact spare tire, see
Changing a Flat Tire on page 9-75.
This information shows you how
to use the vehicle’s tire changing
equipment and how to change a at
tire safely.
{CAUTION
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
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. If a jack is provided
with the vehicle, only use it for
changing a at tire.
9-66 Vehicle Service and Care

Do a safety check before
proceeding. SeeIf a Tire
Goes Flat on page 9-66.
Inspect the damaged tire.
The sealant cannot seal sidewall
damage, large punctures, or a
tire that has unseated from
the wheel. SeeRoadside Assistance
Program on page 12-6.
Do not remove any objects that
have penetrated the tire.
1. Place the tire sealant and
compressor kit on the ground and
unwrap the sealant/air hose (E)
from the side of the compressor.
2. Remove the air compressor
accessory plug (B) from the unit.
Do not plug the plug in yet.3. Turn the tire valve stem cap
counterclockwise to remove.
4. Attach the sealant/air hose (E)
onto the tire valve stem.
Turn it clockwise until tight.
5. Make sure the sealant and
compressor kit on/off switch (A)
is in the O (off) position.
Plug the air compressor
accessory plug (B) into an
accessory power outlet in the
vehicle. SeeAccessory Power
Outlet(s) on page 4-9for
more information.
Do not slam door or close
window on the compressor
accessory plug cord.
{CAUTION
Idling the engine in a closed-in
place or with the climate control
system off can cause deadly
carbon monoxide (CO). See
Engine Exhaust on page 8-14.6. Start the vehicle. The vehicle
must be running while using
the air compressor.
{CAUTION
Overination could cause the tire
to rupture, and you or others
could be injured. Be sure to read
the inator instructions, and inate
the tire to its recommended
pressure. Do not exceed 36 psi
(248 kPa).
7. Push the On/Off switch (A) to the
I (on) position.
The kit will begin to inject sealant
into the tire. Sealant could leak
from the puncture hole until
the vehicle is driven and the hole
has sealed.

19. Wipe off any sealant from the
wheel, tire or vehicle.
20. Dispose of the used sealant
canister at a local dealer/retailer
or in accordance with local
state codes and practices.
After using the sealant canister,
replace it with a new canister
available from your
dealer/retailer.
This is a temporary repair. Take
the vehicle to your
dealer/retailer to have the tire
repaired or replaced as soon as
possible.Using the Air Compressor

9-72 Vehicle Service and Care

Changing a Flat Tire
If a tire goes at, avoid further tire
and wheel damage by driving slowly
to a level place. Turn on the
hazard warning ashers.
{CAUTION
Changing a tire can be dangerous.
The vehicle can slip off the jack
and roll over or fall on you or other
people. You and they could be
badly injured or even killed. Find a
level place to change your tire.
To help prevent the vehicle from
moving:
1. Set the parking brake rmly.
2. Put an automatic
transmission shift lever in
P (Park), or shift a manual
transmission to 1 (First) or
R (Reverse).
(Continued)
CAUTION (Continued)
3. Turn off the engine and do
not restart while the vehicle
is raised.
4. Do not allow passengers to
remain in the vehicle.
To be certain the vehicle will not
move, put blocks at the front and
rear of the tire farthest away from
the one being changed. That
would be the tire on the other
side, at the opposite end of the
vehicle.When you have a at tire, place the
wheel block at the tire diagonally
across from the at tire.
