282 Vehicle Care
Warning (Continued)
A tire and/or wheel could fail
suddenly and cause a crash.
Use only radial-ply tires with
the wheels on the vehicle.
If the vehicle tires must be
replaced with a tire that does not
have a TPC Spec number, make
sure they are the same size,
load range, speed rating, and
construction (radial) as the
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.
See Tire Pressure Monitor
System 0274.
The Tire and Loading
Information label indicates the
original equipment tires on the
vehicle. See Vehicle Load Limits
0 171.Different Size Tires and
Wheels
If wheels or tires are installed that
are a different size than the original
equipment wheels and tires, vehicle
performance, including its braking,
ride and handling characteristics,
stability, and resistance to rollover
may be affected. If the vehicle has
electronic systems such as antilock
brakes, rollover airbags, traction
control, electronic stability control,
or All-Wheel Drive, the performance
of these systems can also be
affected.
{Warning
If different sized wheels are used,
there may not be an acceptable
level of performance and safety if
tires not recommended for those
wheels are selected. This
increases the chance of a crash
and serious injury. Only use GM
specific wheel and tire systems

Uniform Tire Quality
Grading
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 tires,

Do not pinch the power plug
cord in the door or window.
8. Start the vehicle. The vehicle must be running while using
the air compressor.
9. Press the on/off button (7) to turn the tire sealant and
compressor kit on.
The compressor will inject
sealant and air into the tire.
The pressure gauge (3) 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.
10. Inflate the tire to the recommended inflation
pressure using the pressure
gauge (3). The recommended
inflation pressure can be found
on the Tire and Loading
Information label. See Tire
Pressure 0272. The pressure gauge (3) 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.
Caution
If the recommended pressure
cannot be reached after
approximately 10 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 0344.
11. Press the on/off button (7) 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 12–14 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 (5) from the accessory power outlet in
the vehicle.
13. Turn the sealant/air hose (6) counterclockwise to remove it
from the tire valve stem.
14. Replace the tire valve stem cap.
15. Immediately drive the vehicle 8 km (5 mi) but not longer than
10 minutes to distribute the
sealant in the tire.

16. Stop at a safe location andcheck the tire pressure. Refer
to Steps 1–10 under “Using the
Tire Sealant and Compressor
Kit without Sealant to Inflate a
Tire (Not Punctured).”
If the tire pressure has fallen
more than 68 kPa (10 psi)
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 0344.
If the tire pressure has not
dropped more than 68 kPa
(10 psi) from the recommended
inflation pressure, inflate the
tire to the recommended
inflation pressure by using the
compressor to increase the
pressure or turn the air release
valve counterclockwise at the
air filler hose to decrease the
pressure.
17. If the flat tire was able to inflate to the recommended inflation
pressure, remove the
maximum speed label from the
sealant canister and place it in
a highly visible location.
Do not exceed the speed on
this label until the damaged tire
is repaired or replaced.
18. The sealant canister cannot be removed from the compressor.
See your dealer to have the
canister replaced.
19. Return the sealant/air hose (6) and power plug (5) back to
their original storage location.
20. Store the tire sealant and compressor kit in the load
compartment.
21. Wipe off any sealant from the wheel, tire, or vehicle. 22. After temporarily sealing a tire
using the tire sealant and
compressor kit, take the
