The TPMS sensors can also be matched to each
tire/wheel position by increasing or decreasing the tire’s
air pressure. If increasing the tire’s air pressure, do
not exceed the maximum ination pressure indicated on
the tire’s sidewall. To decrease the tire’s air-pressure
use the pointed end of the valve cap, a pencil-style
air pressure gage, or a key.
You have two minutes to match the rst tire/
wheel position, and ve minutes overall, to match
all four tire/wheel positions. If it takes longer than
two minutes, to match the rst tire and wheel, or
more than ve minutes to match all four tire and wheel
positions, the matching process stops and you need
to start over.
The TPMS matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to ON/RUN with the
engine off.
3. Press the Remote Keyless Entry (RKE) transmitter’s
lock and unlock buttons at the same time for
approximately ve seconds. The horn sounds twice
to signal the receiver is in relearn mode and Tire
Learning Active message displays on the DIC
screen.4. Start with the driver side front tire.
5. Remove the valve cap from the valve stem.
Activate the TPMS sensor by increasing or
decreasing the tire’s air pressure for 10 seconds, or
until a horn chirp sounds. The horn chirp, which
can take up to 30 seconds to sound, conrms that
the TPMS sensor identication code has been
matched to this tire position.
6. Proceed to the passenger side front tire, and repeat
the procedure in Step 5.
7. Proceed to the passenger side rear tire, and repeat
the procedure in Step 5.
8. Proceed to the driver side rear tire, and repeat the
procedure in Step 5.
9. After hearing the conrming horn chirp, for the
driver side rear tire, the horn sounds two more
times to signal the tire learning mode is no longer
active. Turn the ignition switch to LOCK/OFF.
10. Set all four tires to the recommended air pressure
level as indicated on the tire and loading information
label.
11. Put the valve caps back on the valve stems.

Different Size Tires and Wheels
If you add wheels or tires that are a different size than
your original equipment wheels and tires, this may
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, antilock brakes, 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 5-78andAccessories
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.

When using the tire sealant and compressor kit during
cold temperatures, warm the kit in a heated environment
for 5 minutes. This will help to inate the tire faster.
Always do a safety check rst. SeeIf a Tire Goes Flat
on page 5-85. Do not remove any objects that have
penetrated the tire.
1. Remove the tire sealant and compressor kit from its
storage location. SeeTire Sealant and Compressor
Kit Storage on page 5-95.
2. Unwrap the sealant/air hose (F) and the power
plug (H).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 at 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 (H) into the accessory power
outlet in the vehicle. Unplug all items from other
accessory power outlets. SeeAccessory Power
Outlet(s) on page 3-22.
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 (A) counterclockwise to the
Sealant + Air position.

9. Press the on/off (B) button to turn the tire sealant
and compressor kit on.
The compressor will inject sealant and air into
the tire.
The pressure gage (C) 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 only.
10. Inate the tire to the recommended ination pressure
using the pressure gage (C). The recommended
ination pressure can be found on the Tire and
Loading Information label. SeeInflation - Tire
Pressure on page 5-69.
The pressure gage (C) 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 inate the tire. Remove the power plug from
the accessory power outlet and unscrew the inating
hose from the tire valve. SeeRoadside Service on
page 7-7.
11. Press the on/off button (B) 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 (H) from the accessory
power outlet in the vehicle.
13. Turn the sealant/air hose (F) counterclockwise to
remove it from the tire valve stem.
