range, speed rating, and
construction (radial) as the
original tires.
The Tire and Loading
Information label indicates
the original equipment tires
on the vehicle. See Vehicle
Load Limits0242.
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 developed
for the vehicle, and have
them properly installed by a
GM certified technician.
See Buying New Tires 0383
and Accessories and
Modifications 0327.
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, compact
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.

environment (shoulder slope,
road debris, etc.). Removal of
some weight may improve the
ability to fit the jack under the
vehicle at the correct jacking
location.
{Warning
Changing a tire can be
dangerous. The vehicle can
slip off the jack and roll over
or fall causing injury or
death. Find a level place to
change the tire. To help
prevent the vehicle from
moving:1. Set the parking brake firmly.
2. Put the vehicle in P (Park).
3. Turn the vehicle off and do not restart the vehicle
while it is raised.
4. Do not allow passengers to remain in the vehicle.
(Continued)
Warning (Continued)
5. Place wheel blocks,if equipped, on both sides
of the tire at the
opposite corner of the
tire being changed.
This vehicle may come with a
jack and spare tire or a tire
sealant and compressor kit. To
use the jacking equipment to
change a spare tire safely,
follow the instructions below.
Then see Tire Changing 0398.
To use the tire sealant and
compressor kit, see Tire
Sealant and Compressor Kit
0 390.
When the vehicle has a flat
tire (2), use the following
example as a guide to assist
you in the placement of wheel
blocks (1), if equipped.
1. Wheel Block (If Equipped)
2. Flat Tire
The following information
explains how to repair or
change a tire.
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 (Continued)

4. Attach the air only hose(10) to the sealant canister
inlet valve (1) by turning it
clockwise until tight.
5. Slide the base of the tiresealant canister (3) into
the slot on the top of the
compressor (6) to hold it
upright.
Make sure the tire valve
stem is positioned close to
the ground so the hose will
reach it. 6. Remove the valve stem
cap from the flat tire by
turning it
counterclockwise.7. Attach the sealant/airhose (2) to the tire valve
stem by turning it
clockwise until tight.
8. Plug the power plug (9) into the accessory power
outlet in the vehicle.
Unplug all items from other
accessory power outlets.
See Power Outlets 0115. 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.
9. Start the vehicle. The vehicle must be running
while using the air
compressor.
10. Press the on/off button (5) to turn the tire sealant and
compressor kit on.
The compressor will inject
sealant and air into
the tire.
The pressure gauge (8) 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.
11. Inflate the tire to the recommended inflation
pressure using the
pressure gauge (8). The
recommended inflation
pressure can be found on
the Tire and Loading
Information label. See Tire
Pressure 0372.
The pressure gauge (8)
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
25 minutes, the vehicle (Continued)
Caution (Continued)
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 0439.
12. Press the on/off button (5) 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 13–
21 must be done
immediately after Step 12.
Be careful while handling
the tire sealant and
compressor kit as it could
be warm after usage. 13. Unplug the power plug (9)
from the accessory power
outlet in the vehicle.
14. Turn the sealant/air hose (2) counterclockwise
to remove it from the tire
valve stem.
15. Replace the tire valve stem cap.
16. Remove the tire sealant canister (4) from the slot
on top of the
compressor (6).
17. Turn the air only hose (10) counterclockwise to
remove it from the tire
sealant canister inlet
valve (1).
18. Turn the sealant/air hose (2) clockwise onto the
sealant canister inlet
valve (1) to prevent sealant
leakage.
19. Return the air only hose (10) and power plug (9)
back to their original
storage location.
