TPMS Sensor Identication Codes
Each TPMS sensor has a unique identication
code. Any time you replace one or more of
the TPMS sensors or rotate the vehicle’s tires,
the identication codes need to be matched to
the new tire/wheel position. The sensors are
matched, to the tire/wheel positions, in the
following order: driver side front tire, passenger
side front tire, passenger side rear tire, and driver
side rear tire using a TPMS diagnostic tool.
See your dealer for service.
The TPMS sensors may also be matched to each
tire/wheel position by increasing or decreasing
the tire’s air pressure. When increasing the tire’s
pressure, do not exceed the maximum ination
pressure indicated on the tire’s sidewall.
You have two minutes to match each tire and
wheel position. If it takes longer than two minutes
to match any tire and wheel position, 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 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 the TPMS sensor
matching process can begin.
4. Start with the driver’s side front tire.
5. Remove the valve cap from the tire’s valve
stem. Activate the TPMS sensor by
increasing or decreasing the tire’s air
pressure for ten seconds, or until a horn
chirp sounds. The horn chirp, which
may take up to 30 seconds to sound,
conrms that the sensor identication code
has been matched to the tire/wheel
position. To decrease the tire’s air-pressure
use the pointed end of the valve cap,
a pencil-style air pressure gage, or a key.

If a Tire Goes Flat (GXP)
GXP models have no spare tire, no tire changing
equipment, and no place for storing a spare or
at tire. If a tire goes at, avoid further tire
and wheel damage by driving slowly to a level
place and stopping. Then do this:
1. Turn on the hazard warning ashers. See
Hazard Warning Flashers on page 134.
2. Park your vehicle. Set the parking brake rmly
and put the shift lever in PARK (P). See
Shifting Into Park (P) on page 116for
additional information.
3. Turn off the engine.
4. Inspect the at tire.
If the tire has been separated from the wheel or
has damaged sidewalls or large tears that
allow rapid air loss, call a tire repair facility. See
Roadside Assistance Program on page 498.
If the at tire is due to a slow leak caused by a nail
or other similar road hazard, the tire inator kit may
be used to temporarily repair the damaged tire.The kit uses a liquid tire sealant to seal small
punctures in the tread area of the tire. The at tire is
then inated to at least 30 psi (207 kPa) and driven
to evenly distribute the tire sealant. The tire
pressure is checked after driving for a maximum of
ve miles (8.0 km) to see if the slow leak has been
stopped. If the tire pressure is 19 psi (131 kPa) or
more, inate the tire up to the standard operating
pressure as shown on the tire and loading
information label. This label is attached to the
vehicle’s center-pillar below the driver’s door latch.
SeeInation - Tire Pressure on page 408.
Notice:If the tire pressure has dropped below
19 psi (131 kPa), the vehicle should not be
driven. Damage to the tire may be severe and
the sealant will not be effective. Contact
Roadside Assistance, seeRoadside Assistance
Program on page 498.
You should have the damaged tire repaired as
soon as possible. The tire sealant is a temporary
repair only. If the tire has been lled with tire
sealant, take the tire to a GM dealer for inspection
and repair. SeeTire Inator Kit (GXP) on
page 424for additional information.

{CAUTION:
Idling the engine in a closed-in place or
with the climate control system off can
cause deadly carbon monoxide (CO). See
Engine Exhaust on page 119.
6. Start the vehicle. SeeStarting the Engine on
page 107for 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).7. Move the inator kit switch to the I (on)
position.
The inator kit will force sealant and air into
the tire. Sealant may leak from the puncture
hole until the vehicle is driven and the hole
has sealed.
8. Make sure there is a proper connection
between the tire valve stem and the
sealant lling hose by looking at the air
pressure gage. If there is not a pressure
reading while the compressor is running, the
connection between the inator kit and
the tire is bad.
Check the attachment between the sealant
lling hose and the tire valve stem.
428

9. Inate the tire up 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 as a guide.
The pressure gage reading is slightly high
while the compressor is on. 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. See
Roadside Assistance Program on page 498.10. Move the inator kit switch to the O (off)
position once the correct tire pressure is
obtained.
11. Turn off the engine.
12. Unplug the air compressor accessory plug
from the accessory power outlet in the
vehicle.
13. 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 may be hot after usage.
14. Wrap the sealant lling hose around the air
compressor channel to stow it in its original
location.
15. 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.

4. Push the air compressor inator hose onto the
tire valve stem and push the lever down to
secure in place.
5. Plug the air compressor accessory plug into
an accessory power outlet in the vehicle. See
Accessory Power Outlet(s) on page 156for
more information.
{CAUTION:
Idling the engine in a closed-in place or
with the climate control system off can
cause deadly carbon monoxide (CO). See
Engine Exhaust on page 119.
6. Start the vehicle. SeeStarting the Engine on
page 107for 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).
7. Move the inator kit switch to the I (on)
position.
8. Make sure there is a proper connection
between the tire valve stem and the air
compressor hose by looking at the air
pressure gage. If there is not a pressure
reading while the compressor is running, the
connection between the inator kit and
the tire is bad.
Check the attachment between the air
compressor hose and the tire valve stem.

Changing a Flat Tire
If a tire goes at, avoid further tire and wheel
damage by driving slowly to a level place. Turn on
your vehicle’s hazard warning ashers. See
Hazard Warning Flashers on page 134for more
information.
{CAUTION:
Changing a tire can be dangerous. The
vehicle can slip off the jack and roll over
or fall on you or other people. You and
they could be badly injured or even killed.
Find a level place to change your tire. To
help prevent the vehicle from moving:
1. Set the parking brake rmly.
2. Put the shift lever in PARK (P).
CAUTION: (Continued)
CAUTION: (Continued)
3. Turn off the engine and do not restart
while the vehicle is raised.
4. Do not allow passengers to remain in
the vehicle.
To be even more certain the vehicle will
not move, you should put blocks at the
front and rear of the tire farthest away
from the one being changed. That would
be the tire, on the other side, at the
opposite end of the vehicle.
