{CAUTION:
Mixing tires could cause you to lose control while
driving. If you mix tires of different sizes (other than
those originally installed on your vehicle), brands, or
types (radial and bias-belted tires), the vehicle may
not handle properly, and you could have a crash.
Using tires of different sizes (other than those
originally installed on your vehicle), brands, or types
may also cause damage to your vehicle. Be sure to
use the correct size, brand, and type of tires on all
wheels. It is all right to drive with your vehicle’s
compact spare temporarily, it was developed for
use on your vehicle. SeeCompact Spare Tire on
page 5-114.
{CAUTION:
If you use bias-ply tires on the vehicle, the
wheel rim anges could develop cracks after
many miles of driving. A tire and/or wheel
could fail suddenly, causing a crash. Use
only radial-ply tires with the wheels on the
vehicle.
If you must replace your vehicle’s tires with those
that do not have a TPC Spec number, make sure
they are the same size, load range, speed rating,
and construction type (radial and bias-belted tires)
as your vehicle’s original tires.
Vehicles that have a tire pressure monitoring
system could give an inaccurate low-pressure
warning if non-TPC Spec rated tires are installed
on it. Non-TPC Spec rated tires may give a
low-pressure warning that is higher or lower
than the proper warning level you would get with
TPC Spec rated tires. SeeTire Pressure Monitor
System on page 5-66.

If you need to replace any of your wheels, wheel bolts,
wheel nuts, or Tire Pressure Monitor System (TPMS)
sensors, replace them only with new GM original
equipment parts. This way, you will be sure to have
the right wheel, wheel bolts, wheel nuts, and TPMS
sensors for your 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 5-104for more
information.
Used Replacement Wheels
{CAUTION:
Putting a used wheel on the vehicle is dangerous.
You cannot know how it has been used or how
far it has been driven. It could fail suddenly and
cause a crash. If you have to replace a wheel,
use a new GM original equipment wheel.

Run-Flat Tires (STS-V)
If this vehicle has run- at tires, there is no spare tire
and no tire changing equipment. Run- at tires can
operate effectively with no air pressure for a limited
distance and speed. These tires perform so well without
any air pressure that a Tire Pressure Monitor (TPM)
is used to alert you when there is a low tire condition.
{CAUTION:
When the low tire warning light is displayed
on the instrument panel cluster, your vehicle’s
handling capabilities will be reduced during severe
maneuvers. If you drive too fast, you could lose
control of your vehicle. You or others could be
injured. Do not drive over 55 mph (90 km/h)
when the low tire warning light is displayed.
Drive cautiously and check your tire pressures
as soon as you can.SeeRun-Flat Tires (STS-V) on page 5-62andTire
Pressure Monitor System on page 5-66, for additional
information.
{CAUTION:
Special tools and procedures are required to
service a run- at tire. If these special tools and
procedures are not used you or others could
be injured and the vehicle could be damaged.
Always be sure the proper tools and procedures,
as described in the service manual, are used.
To order a service manual seeService Publications
Ordering Information on page 7-15.

{CAUTION:
Idling a vehicle in an enclosed area with poor
ventilation is dangerous. Engine exhaust may
enter the vehicle. Engine exhaust contains Carbon
Monoxide (CO) which cannot be seen or smelled.
It can cause unconsciousness and even death.
Never run the engine in an enclosed area that has
no fresh air ventilation. For more information, see
Engine Exhaust on page 2-36.
{CAUTION:
Over-in ating a tire could cause the tire to rupture
and you or others could be injured. Be sure to
read and follow the tire sealant and compressor kit
instructions and in ate the tire to its recommended
pressure. Do not exceed the recommended
pressure.
{CAUTION:
Storing the tire sealant and compressor kit or
other equipment in the passenger compartment of
the vehicle could cause injury. In a sudden stop or
collision, loose equipment could strike someone.
Store the tire sealant and compressor kit in its
original location.
If this vehicle has a tire sealant and compressor kit,
there may not be a spare tire, tire changing equipment,
and on some vehicles there may not be a place to
store a tire.
The tire sealant and compressor can be used to
temporarily seal punctures up to
1 4inch (6 mm) in the
tread area of the tire. It can also be used to in ate
an under in ated tire.
If the tire has been separated from the wheel, has
damaged sidewalls, or has a large puncture, the tire is
too severely damaged for the tire sealant and
compressor kit to be effective. SeeRoadside Service on
page 7-7.

Read and follow all of the tire sealant and compressor
kit instructions.
The kit includes:
A. Air Compressor
B. Tire Sealant Canister
C. Power Plug
D. On/Off Button
E. Pressure GageF. Air Only Hose
(Black)
G. Sealant/Air Hose
(Clear)Tire Sealant
Read and follow the safe handling instructions on the
label adhered to the sealant canister.
Check the tire sealant expiration date on the sealant
canister. The sealant canister should be replaced before
its expiration date. Replacement sealant canisters are
available at your local dealer/retailer. See “Removal and
Installation of the Sealant Canister” following.
There is only enough sealant to seal one tire. After
usage, the sealant canister and sealant/air hose
assembly must be replaced. See “Removal and
Installation of the Sealant Canister” following.

7. Start the vehicle. The vehicle must be running while
using the air compressor.
8. Press the on/off (D) button to turn the tire sealant
and compressor kit on.
The compressor will inject sealant and air into
the tire.
The pressure gage (E) will initially show a high
pressure while the compressor pushes the sealant
into the tire. Once the sealant is completely
dispersed into the tire, the pressure will quickly drop
and start to rise again as the tire in ates with air only.
9. In ate the tire to the recommended in ation
pressure using the pressure gage (E). The
recommended in ation pressure can be found
on the Tire and Loading Information label.
SeeInflation - Tire Pressure on page 5-64.
The pressure gage (E) may read higher than the
actual tire pressure while the compressor is on.
Turn the compressor off to get an accurate pressure
reading. The compressor may be turned on/off
until the correct pressure is reached.Notice:If the recommended pressure cannot be
reached after approximately 25 minutes, the vehicle
should not be driven farther. The tire is too severely
damaged and the tire sealant and compressor kit
cannot in ate the tire. Remove the power plug from
the accessory power outlet and unscrew the in ating
hose from the tire valve. SeeRoadside Service on
page 7-7.
10. Press the on/off button (D) to turn the tire sealant
and compressor kit off.
The tire is not sealed and will continue to leak
air until the vehicle is driven and the sealant is
distributed in the tire, therefore, Steps 11 through 17
must be done immediately after Step 10.
Be careful while handling the tire sealant and
compressor kit as it could be warm after usage.
11. Unplug the power plug (C) from the accessory
power outlet in the vehicle.
12. Turn the sealant/air hose (F) counterclockwise to
remove it from the tire valve stem.
13. Replace the tire valve stem cap.
14. Replace the sealant/air hose (F), and the power
plug (C) back in their original location.

15. If the at tire was
able to in ate to the
recommended in ation
pressure, remove the
maximum speed label
from the sealant
canister (B) and place
it in a highly visible
location.
The label is a reminder not to exceed 55 mph
(90 km/h) until the damaged tire is repaired
or replaced.
16. Return the equipment to its original storage location
in the vehicle.
17. Immediately drive the vehicle 5 miles (8 km) to
distribute the sealant in the tire.
18. Stop at a safe location and check the tire pressure.
Refer to Steps 1 through 11 under “Using the Tire
Sealant and Compressor Kit without Sealant to
In ate a Tire (Not Punctured).”If the tire pressure has fallen more than 10 psi
(68 kPa) below the recommended in ation pressure,
stop driving the vehicle. The tire is too severely
damaged and the tire sealant cannot seal the tire.
SeeRoadside Service on page 7-7.
If the tire pressure has not dropped more than
10 psi (68 kPa) from the recommended in ation
pressure, in ate the tire to the recommended
in ation pressure.
19. Wipe off any sealant from the wheel, tire, and
vehicle.
20. Dispose of the used sealant canister (B) and
sealant/air hose (F) assembly at a local dealer/
retailer or in accordance with local state codes
and practices.
21. Replace it with a new canister available from your
dealer/retailer.
22. After temporarily sealing a tire using the tire sealant
and compressor kit, take the vehicle to an authorized
dealer/retailer within a 100 miles (161 km) of driving
to have the tire repaired or replaced.

11. In ate the tire to the recommended in ation pressure
using the pressure gage (E). The recommended
in ation pressure can be found on the Tire and
Loading Information label. SeeInflation - Tire
Pressure on page 5-64.
The pressure gage (E) may read higher than the
actual tire pressure while the compressor is on. Turn
the compressor off to get an accurate reading.
The compressor may be turned on/off until
the correct pressure is reached.
12. Press the on/off button (D) to turn the tire sealant
and compressor kit off.
