Different Size Tires and Wheels
If you add wheels or tires that are a different size than
your original equipment wheels and tires, this could
affect the way your vehicle performs, including its
braking, ride and handling characteristics, stability, and
resistance to rollover. Additionally, if your vehicle has
electronic systems such as anti-lock brakes, rollover
airbags, traction control, and electronic stability control,
the performance of these systems can be affected.
{CAUTION:
If you add different sized wheels, your vehicle
may not provide an acceptable level of
performance and safety if tires not
recommended for those wheels are selected.
You may increase the chance that you will
crash and suffer serious injury. Only use GM
specic wheel and tire systems developed for
your vehicle, and have them properly installed
by a GM certied technician.
SeeBuying New Tires on page 5-69andAccessories
and Modifications on page 5-3for additional information.
Uniform Tire Quality Grading
Quality grades can be found where applicable
on the tire sidewall between tread shoulder
and maximum section width. For example:
Treadwear 200 Traction AA Temperature A
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration (NHTSA), which
grades tires by treadwear, traction, and
temperature performance. This applies only to
vehicles sold in the United States. The grades are
molded on the sidewalls of most passenger car
tires. The Uniform Tire Quality Grading (UTQG)
system does not apply to deep tread, winter-type
snow tires, space-saver, or temporary use
spare tires, tires with nominal rim diameters of
10 to 12 inches (25 to 30 cm), or to some
limited-production tires.
While the tires available on General Motors
passenger cars and light trucks may vary with
respect to these grades, they must also conform
to federal safety requirements and additional
General Motors Tire Performance Criteria (TPC)
standards.

Tire Sealant
Read and follow the safety handling instructions on the
sealant canister.
The sealant can temporarily seal a puncture up to
14inch (6 mm) in the tread area of the tire. The sealant
cannot seal sidewall damage, large punctures, or a
tire that has unseated from the wheel. SeeRoadside
Assistance Program on page 7-6if you need assistance.
The sealant can only be used to seal one tire. After
usage, the sealant canister and the sealant lling hose
assembly must be replaced at a dealer/retailer. See
Removal and Installation of Sealant Canister later in this
section.
Check the tire sealant expiration date on the sealant
canister, if it has expired, see your dealer/retailer for a
replacement.
Using the Tire Sealant and Compressor
Kit to Temporarily Seal a Punctured Tire
Follow the directions closely for correct sealant usage.
1. Place the sealant and compressor kit on the ground
and unwrap the sealant lling hose from the
compressor.
2. Remove the air compressor accessory plug from
the unit. To do this, pull the top portion of the
wrapped cord out rst, then the bottom, and then
unsnap the plug. Do not insert the plug into an
accessory outlet yet.
3. Remove the valve stem or tire pressure monitoring
sensor cap from the at tire by turning it
counterclockwise.
If an object, such as a nail, has penetrated the tire,
do not remove it.
5-78

4. Attach the sealant lling hose (A) onto the tire valve
stem. Turn it clockwise until it is tight.
Make sure the sealant and compressor kit on/off
switch (B) is in the O (off) position.
5. Plug the air compressor accessory plug (C) into an
accessory power outlet in the vehicle. SeeAccessory
Power Outlet(s) on page 3-20for 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). SeeEngine
Exhaust on page 2-37.
6. Start the vehicle. SeeStarting the Engine (Key
Access) on page 2-25for more information.
The vehicle must be running while using the air
compressor.
{CAUTION:
Inating something too much can make it
explode, 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).
5-79

7. Push the On/Off switch to the I (on) position.
The sealant and compressor kit injects sealant
and air into the tire. Sealant can leak from
the puncture until the vehicle is driven and the hole
has sealed.
The pressure gage 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 inates with air.
8. Inate the tire to the recommended ination
pressure, found on the Tire and Loading Information
label located on the vehicle’s center pillar (B-pillar)
below the vehicle’s door latch, using the air pressure
gage on the top of the unit.
The pressure gage reads high while the compressor
is running. Turn the compressor off to get an
accurate pressure reading.
Notice:If the recommended pressure cannot be
reached after 15 minutes, the vehicle should not be
driven farther. Damage to the tire is severe and
the sealant will not be effective. Remove the
air compressor plug from the accessory power
outlet and unscrew the inating hose from the tire
valve. SeeRoadside Assistance Program on
page 7-6for more information.9. Push the sealant and compressor kit switch to the
O (off) position.
10. The tire is not sealed and will continue to leak air
until the vehicle is driven and the sealant is
distributed in the tire.
Steps 11 through 18 must be done right after
Step 9.
11. Unplug the air compressor accessory plug from the
accessory power outlet in the vehicle.
12. Disconnect the sealant lling hose from the tire
valve stem, by turning it counterclockwise, and
replace the tire valve stem cap.
Be careful when handling the tire inator
components as they could be hot after usage.
13. Wrap the sealant lling hose around the air
compressor channel to stow it in its original location.
14. Stow the air compressor accessory plug back in the
air compressor. To do this, wrap the air compressor
accessory plug, snap in the plug, and then push
in the bottom and then the top of the wrapped
air compressor accessory plug.
5-80

15. If the at tire was able
to inate to the
recommended ination
pressure, remove
the maximum speed
label from the sealant
canister.
The maximum speed label reminds you to drive
cautiously and not to exceed 55 mph (90 km/h)
until you have the damaged tire inspected
and repaired.
16. Place it in a highly visible location such as the
inside of the upper left corner of the windshield
or to the face of the radio/clock.
17. Return the equipment to the proper storage location
in the rear of your vehicle. To do this, insert the tire
sealant and compressor kit back into the foam
container and place the foam container onto the
storage bracket. Securely tighten down the
foam container with the foam retainer bolt.
{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 the proper place.
18. Reverse Steps 1 through 4 under Accessing the
Tire Sealant and Compressor Kit earlier in this
section.
19. Immediately drive the vehicle 5 miles (8 km) to
distribute the sealant evenly in the tire. Stop at a
safe location and check the tire pressure, refer
to Steps 1 through 8 under Using the Air
Compressor without Sealant next in this section.
If the tire pressure has not dropped more than
10 psi (68 kPa) from the recommended ination
pressure, you can inate the tire back up to
the recommended ination pressure.
5-81

20. If the tire pressure has fallen more then 10 psi
(68 kPa), below the recommended ination
pressure, stop driving the vehicle. The tire is
too severely damaged and the tire sealant and
compressor kit cannot seal the tire. SeeRoadside
Assistance Program on page 7-6for more
information.
21. Wipe off any sealant from the wheel, tire and
vehicle with a rag.
22. Dispose of the sealant canister at a local
dealer/retailer or in accordance with any local, state,
and provincial codes and practices.
After using the sealant canister, replace it with a
new canister from a dealer/retailer.
23. After temporarily sealing a tire with the tire sealant
and compressor kit, take your vehicle to an
authorized dealer/retailer to have the tire inspected
and repaired.Using the Air Compressor without
Sealant to Inate an Underinated Tire
(Not Punctured)
To use the air compressor to inate a tire with air only
and not sealant:
1. Remove the air compressor inating hose connector
from the bottom of the air compressor.
2. Unlock the air compressor hose from the sealant
canister by pulling up on the lever.
3. Pull the air compressor inator hose from the
sealant canister.
