driver's responsibility to
maintain correct tire pressure,
even if under-inflation has not
reached the level to trigger
illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been
equipped with a TPMS
malfunction indicator to
indicate when the system is
not operating properly. The
TPMS malfunction indicator is
combined with the low tire
pressure telltale. When the
system detects a malfunction,
the telltale will flash for
approximately one minute and
then remain continuously
illuminated. This sequence will
continue upon subsequent
vehicle start-ups as long as
the malfunction exists.
When the malfunction
indicator is illuminated, the
system may not be able to
detect or signal low tire
pressure as intended. TPMS
malfunctions may occur for a
variety of reasons, includingthe installation of replacement
or alternate tires or wheels on
the vehicle that prevent the
TPMS from functioning
properly. Always check the
TPMS malfunction telltale
after replacing one or more
tires or wheels on your vehicle
to ensure that the
replacement or alternate tires
and wheels allow the TPMS to
continue to function properly.

See Radio Frequency
Statement 0477.
Tire Pressure Monitor
Operation
This vehicle may have a Tire
Pressure Monitor System
(TPMS). The TPMS is designed
to warn the driver when a low
tire pressure condition exists.
TPMS sensors are mounted
onto each tire and wheel
assembly, excluding the spare
tire and wheel assembly. The
TPMS sensors monitor the air pressure in the tires and
transmit the tire pressure
readings to a receiver located
in the vehicle.
When a low tire pressure
condition is detected, the
TPMS illuminates the low tire
pressure warning light on the
instrument cluster. If the
warning light comes on, stop
as soon as possible and inflate
the tires to the recommended
pressure shown on the Tire
and Loading Information label.
See Vehicle Load Limits
0252.
A message to check the
pressure in a specific tire
displays in the Driver
Information Center (DIC). The
low tire pressure warning light
and the DIC warning message
come on at each ignition cycle
until the tires are inflated to

lamp is still flashing, briefly
press the center of the valve
stem. When the recommended
pressure is reached, the horn
sounds once.
If the turn signal lamp does
not flash within 15 seconds
after starting to inflate the
tire, the tire fill alert has not
been activated or is not
working.
If the hazard warning flashers
are on, the tire fill alert visual
feedback will not work
properly.
The TPMS will not activate the
tire fill alert properly under the
following conditions:
.There is interference from
an external device or
transmitter.
.The air pressure from the
inflation device is not
sufficient to inflate the tire.
.There is a malfunction in
the TPMS.
.There is a malfunction in the
horn or turn signal lamps.
.The identification code of
the TPMS sensor is not
registered to the system.
.The battery of the TPMS
sensor is low.
If the tire fill alert does not
operate due to TPMS
interference, move the vehicle
about 1 m (3 ft) back or
forward and try again. If the
tire fill alert feature is not
working, use a tire pressure
gauge.
TPMS Sensor Matching
Process
Each TPMS sensor has a
unique identification code. The
identification code needs to be
matched to a new tire/wheel
position after rotating the
vehicle’s tires or replacing one
or more of the TPMS sensors.
The TPMS sensor matching
process should also be
performed after replacing a
spare tire with a road tire
containing the TPMS sensor.
The malfunction light and the DIC message should go off at
the next ignition cycle. The
sensors are matched to the
tire/wheel positions, using a
TPMS relearn tool, in the
following order: driver side
front tire, passenger side front
tire, passenger side rear tire,
and driver side rear. See your
dealer for service or to
purchase a relearn tool.
A TPMS relearn tool can also
be purchased. See Tire
Pressure Monitor Sensor
Activation Tool at www.
gmtoolsandequipment.com or
call 1-800-GM TOOLS
(1-800-468-6657).
There are two minutes to
match the first tire/wheel
position, and five minutes
overall to match all four tire/
wheel positions. If it takes
longer, the matching process
stops and must be restarted.
The TPMS sensor matching
process is:
1. Set the parking brake.

{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.
5. Place wheel blocks, if equipped, on both sides
of the tire at the
opposite corner of the
tire being changed. When the vehicle has a flat
tire (2), use the following
example as a guide to assist in
the placement of the 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 Changing
Performance Brake
Package RPO J56
The original spare tire/wheel
will not fit onto the front axle if
equipped with the
performance brake package RPO J56. If there is a flat tire
on the front axle, a tire/wheel
from the rear axle must be
used to make the repair. The
spare tire will then replace the
tire/wheel that is removed
from the rear axle.
If equipped with the
performance brake package
RPO J56, and the flat tire is on
the front axle, stop after
performing all steps in
Removing the Spare Tire and
Tools and do the following.
Otherwise, continue with the
