Your dealer 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 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.
{WARNING:
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.
See Changing a Flat Tire
on page 6‑90for more
information.
Used Replacement Wheels
{WARNING:
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.

If a Tire Goes Flat
It is unusual for a tire to blowout while you are driving,
especially if you maintain your vehicle's tires properly.
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 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 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.{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.
This vehicle may come with a jack and spare tire or a
tire sealant and compressor kit. To use the jack and
spare tire, follow the instructions below. To use the tire
sealant and compressor kit, see Tire Sealant and
Compressor Kit
on page 6‑82.
6-81

Tire Sealant and Compressor Kit
{WARNING:
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, seeEngine Exhaust on page 3‑31.
{WARNING:
Over-inflating 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 inflate the tire to its
recommended pressure. Do not exceed the
recommended pressure.
{WARNING:
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.
6-82

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 ¼ inch (6 mm) in the
tread area of the tire. It can also be used to inflate an
under inflated 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
Assistance Program on page 8‑8.
Read and follow all of the tire sealant and compressor
kit instructions. The kit includes:
A. On/Off Button
B. Selector Switch
(Sealant/Air or Air Only)
C. Pressure Relief Button
D. Pressure Gauge E. Air Only Hose
(Black)
F. Sealant/Air Hose (Clear)
G. Power Plug
6-83

Always do a safety check first. SeeIf a Tire Goes Flaton page 6‑81. Do not remove any objects that have
penetrated the tire.
1. Remove the tire sealant and compressor kit from its storage location. See Tire Sealant and
Compressor Kit Storage on page 6‑90.
2. Unwrap the sealant/air hose (F) and the power plug (G).
3. Place the kit on the ground.
Make sure the tire valve stem is positioned close to
the ground so the hose will reach it.
4. Remove the valve stem cap from the flat tire by turning it counterclockwise.
5. Attach the sealant/air hose (F) onto the tire valve stem. Turn it clockwise until it is tight.
6. Plug the power plug (G) into the accessory power outlet in the vehicle. Unplug all items from other
accessory power outlets. See Accessory Power
Outlet(s) on page 4‑17. If the vehicle has an accessory power outlet, do
not use the cigarette lighter.
If the vehicle only has a cigarette lighter, use the
cigarette lighter.
Do not pinch the power plug cord in the door or
window.
7. Start the vehicle. The vehicle must be running while using the air compressor.
8. Turn the selector switch (B) clockwise to the Sealant + Air position.
9. Press the on/off (A) button to turn the tire sealant and compressor kit on.
The compressor will inject sealant and air into
the tire.
The pressure gauge (D) 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 inflates with
air only.
6-85

10. Inflate the tire to the recommended inflationpressure using the pressure gauge (D). The
recommended inflation pressure can be found on
the Tire and Loading Information label. See
Inflation - Tire Pressure on page 6‑65.
The pressure gauge (D) 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 inflate the tire. Remove the power plug from
the accessory power outlet and unscrew the
inflating hose from the tire valve. See Roadside
Assistance Program on page 8‑8.
11. Press the on/off button (A) 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 12
through 18 must be done immediately after
Step 11.
Be careful while handling the tire sealant and
compressor kit as it could be warm after usage. 12. Unplug the power plug (G) from the accessory
power outlet in the vehicle.
13. Turn the sealant/air hose (F) counterclockwise to remove it from the tire valve stem.
14. Replace the tire valve stem cap.
15. Replace the sealant/air hose (F), and the power plug (G) back in their original location.
16. If the flat tire wasable to inflate to the
recommended inflation
pressure, remove the
maximum speed label
from the sealant
canister 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.
17. Return the equipment to its original storage location in the vehicle.
18. Immediately drive the vehicle 5 miles (8 km) to distribute the sealant in the tire.
6-86

19. 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
Inflate a Tire (Not Punctured).”
If the tire pressure has fallen more than 10 psi
(68 kPa) below the recommended inflation
pressure, stop driving the vehicle. The tire is too
severely damaged and the tire sealant cannot seal
the tire. See Roadside Assistance Program
on
page 8‑8.
If the tire pressure has not dropped more than
10 psi (68 kPa) from the recommended inflation
pressure, inflate the tire to the recommended
inflation pressure.
20. Wipe off any sealant from the wheel, tire, and vehicle.
21. Dispose of the used sealant canister and sealant/ air hose (F) assembly at a local dealer or in
accordance with local state codes and practices.
22. Replace it with a new canister available from your dealer.
23. After temporarily sealing a tire using the tire sealant and compressor kit, take the vehicle to an
authorized dealer within a 100 miles (161 km) of
driving to have the tire repaired or replaced.
Using the Tire Sealant and Compressor
Kit without Sealant to Inflate a Tire
(Not Punctured)
To use the air compressor to inflate a tire with air only
and not sealant:
Always do a safety check first. See If a Tire Goes Flaton page 6‑81.
1. Remove the tire sealant and compressor kit from its storage location. See Tire Sealant and
Compressor Kit Storage on page 6‑90.
2. Unwrap the air only hose (E) and the power plug (G).
