{Warning
Using bias-ply tires on
the vehicle may cause the
wheel rim flanges to
develop cracks after
many miles of driving.
A tire and/or wheel could
fail suddenly and cause a
crash. Use only radial-ply
tires with the wheels on
the vehicle.
Winter tires with the same
speed rating as the original
equipment tires may not be
available for H, V, W, Y and
ZR speed rated tires. Never
exceed the winter tires’
maximum speed capability
when using winter tires
with a lower speed rating.
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.
The Tire and Loading
Information label indicates
the original equipment tires
on the vehicle. See Vehicle
Load Limits
0261.
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.

and

446 Vehicle Care
If a tire goes flat, avoid further
tire and wheel damage by
driving slowly to a level place.
Turn on the hazard warning
flashers. See Hazard Warning
Flashers0156.
See If a Tire Goes Flat 0443
for other important safety
warnings.
Do not remove any objects
that have penetrated the tire.
1. Remove the tire sealant canister (4) and
compressor from its
storage location. See
Storing the Tire Sealant
and Compressor Kit 0451.
2. Remove the air only hose (10) and the power plug (9)
from the bottom of the
compressor.
3. Place the compressor on the ground near the
flat tire.
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 0108.
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 0427.
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
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
0489.
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
