Remove the valve cap from the tire valve stem.
Press the tire gage rmly onto the valve to
get a pressure measurement. If the cold tire
ination pressure matches the recommended
pressure on the Tire and Loading Information
label, no further adjustment is necessary.
If the ination pressure is low, add air until you
reach the recommended amount.
If you overll the tire, release air by pushing on
the metal stem in the center of the tire valve.
Re-check the tire pressure with the tire gage.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out
dirt and moisture.
Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses radio
and sensor technology to check tire pressure levels.
The TPMS sensors monitor the air pressure in
your vehicle’s tires and transmit tire pressure readings
to a receiver located in the vehicle.Each tire, including the spare (if provided), should be
checked monthly when cold and inated to the ination
pressure recommended by the vehicle manufacturer
on the vehicle placard or tire ination pressure label.
(If your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire ination
pressure label, you should determine the proper
tire ination pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system (TPMS)
that illuminates a low tire pressure telltale when one
or more of your tires is signicantly under-inated.
Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires as
soon as possible, and inate them to the proper
pressure. Driving on a signicantly under-inated tire
causes the tire to overheat and can lead to tire failure.
Under-ination also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling
and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if under-ination
has not reached the level to trigger illumination of
the TPMS low tire pressure telltale.

Tire Pressure Monitor Operation
The Tire Pressure Monitor System (TPMS) is designed
to warn the driver when a low tire pressure condition
exists. TPMS sensors are mounted onto each tire and
wheel assembly. The TPMS sensors monitor the
air pressure in the vehicle’s tires and transmits the tire
pressure readings to a receiver located in the vehicle.
When a low tire pressure
condition is detected, the
TPMS turns on the low
tire pressure warning light
located on the instrument
panel cluster.
At the same time a message to check the pressure in a
specic tire appears on the Driver Information Center
(DIC) display. The low tire pressure warning light
and the DIC warning message come on at each ignition
cycle until the tires are inated to the correct ination
pressure. Using the DIC, tire pressure levels can
be viewed by the driver.For additional information and details about the DIC
operation and displays seeDIC Operation and Displays
on page 3-44andDIC Warnings and Messages on
page 3-46.
The low tire pressure warning light may come on in
cool weather when the vehicle is rst started, and then
turn off as you start to drive. This could be an early
indicator that the air pressure in the tire(s) are getting
low and need to be inated to the proper pressure.
A Tire and Loading Information label shows the size of
your vehicle’s original equipment tires and the correct
ination pressure for your vehicle’s tires when they are
cold. SeeLoading Your Vehicle on page 4-22, for an
example of the Tire and Loading Information label and
its location on your vehicle. Also seeInflation - Tire
Pressure on page 5-52.
Your vehicle’s TPMS system can warn you about a low
tire pressure condition but it does not replace normal
tire maintenance. SeeTire Inspection and Rotation
on page 5-58andTires on page 5-46.
Notice:Using non-approved tire sealants could
damage the Tire Pressure Monitor System (TPMS)
sensors. TPMS sensor damage caused by using
an incorrect tire sealant is not covered by the
vehicle warranty. Always use the GM approved tire
sealant available through your dealer/retailer.
5-55

TPMS Malfunction Light and Message
The TPMS will not function properly if one or more of the
TPMS sensors are missing or inoperable. When the
system detects a malfunction, the low tire warning light
ashes for about one minute and then stays on for the
remainder of the ignition cycle. A DIC warning message is
also displayed. The low tire warning light and DIC warning
message come on at each ignition cycle until the problem
is corrected. Some of the conditions that can cause the
malfunction light and DIC message to come on are:
The TPMS sensor matching process was started but
not completed or not completed successfully after
rotating the vehicle’s tires. The DIC message and
TPMS malfunction light should go off once the TPMS
sensor matching process is performed successfully.
See “TPMS Sensor Matching Process” later in this
section.
One or more TPMS sensors are missing or
damaged. The DIC message and the TPMS
malfunction light should go off when the TPMS
sensors are installed and the sensor matching
process is performed successfully. See your
dealer/retailer for service.
Replacement tires or wheels do not match your
vehicle’s original equipment tires or wheels. Tires
and wheels other than those recommended for your
vehicle could prevent the TPMS from functioning
properly. SeeBuying New Tires on page 5-60.
Operating electronic devices or being near facilities
using radio wave frequencies similar to the TPMS
could cause the TPMS sensors to malfunction.
If the TPMS is not functioning it cannot detect or
signal a low tire condition. See your dealer/retailer for
service if the TPMS malfunction light and DIC message
comes on and stays on.
TPMS Sensor Matching Process
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 location.
The sensors are matched, to the tire/wheel locations,
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/retailer for service.
The TPMS sensors can 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. To decrease the tire’s
air-pressure use the pointed end of the valve cap,
a pencil-style air pressure gage, or a key.
5-56

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 ON/RUN with the
engine off.
3. Press and hold the Remote Keyless Entry (RKE)
transmitter’s LOCK and UNLOCK buttons, at the
same time, for about ve seconds to start the TPMS
learn mode. The horn sounds twice indicating the
TPMS receiver is ready and in learn mode.
4. Start with the driver side front tire. The driver side
front turn signal also comes on to indicate that
corner’s sensor is ready to be learned.
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 about
eight seconds. The horn chirp, can take up to
30 seconds to sound. It chirps one time and then
all the turn signals ash one time to conrm
the sensor identication code has been matched
to the tire/wheel position.6. The passenger side front turn signal comes on to
indicate that corner sensor is ready to be learned.
Proceed to the passenger side front tire and
repeat the procedure in Step 5.
7. The passenger side rear turn signal comes on to
indicate that corner sensor is ready to be learned.
Proceed to the passenger side rear tire and
repeat the procedure in Step 5.
8. The driver side rear turn signal comes on to
indicate that corner sensor is ready to be learned.
Proceed to the driver side rear tire, and repeat
the procedure in Step 5.
9. After hearing the single horn chirp for the driver
side rear tire, two additional horn chirps sound
to indicate the tire learning process is done.
Turn the ignition switch to LOCK/OFF.
If no tires are learned after entering the TPMS learn
mode, or if communication with the receiver stops,
or if the time limit has expired, turn the ignition switch
to LOCK/OFF and start over beginning with Step 2.
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.

Using the Tire Sealant and
Compressor Kit to Temporarily
Seal a Punctured Tire
Follow these directions closely for correct sealant usage.
1. Place the sealant and compressor kit on the ground
and unwrap the sealant lling hose from the
compressor.
2. Remove the air compressor accessory plug from
the unit. To do this, pull the top portion of the
wrapped cord out rst, then the bottom, and then
unsnap the plug. Do not insert the plug into an
accessory outlet yet.
3. Remove the valve stem or tire pressure monitoring
sensor cap from the at tire by turning it
counterclockwise.
If an object, such as a nail, has penetrated the tire,
do not remove it.4. Attach the sealant lling hose (A) onto the tire valve
stem. Turn it clockwise until it is tight.
Make sure the sealant and compressor kit on/off
switch (B) is in the O (off) position.
5-70

8. Inate the tire 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.
The pressure gage reads high while the compressor
is running. 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. The tire is too severely damaged
and cannot be inated or sealed with the tire sealant
and compressor kit. Remove the air compressor
accessory plug from the accessory power outlet
and unscrew the sealant lling hose from the
tire valve or tire pressure monitoring sensor valve.
SeeRoadside Assistance Program on page 7-7.
9. Push the On/Off switch to the O (off) position
once the correct tire pressure is obtained.
10. The tire is not sealed and will continue to leak
air until the vehicle is driven and the sealant is
distributed in the tire.
Steps 11 through 17 must be done right after
Step 10.
11. Unplug the air compressor accessory plug from
the accessory power outlet in the vehicle.12. 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 could be hot after usage.
13. Wrap the sealant lling hose around the air
compressor channel to stow it in its original location.
14. 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.
15. If the at tire was
able to inate to the
recommended ination
pressure, remove
the maximum speed
label from the sealant
canister.
Place it in a highly visible location such as the
inside of the upper left corner of the windshield
or to the face of the radio/clock.
