SERVICE TIRE MONITOR
This message will be displayed if any of the tire monitor
sensors have malfunctioned, if the tire monitor sensors
have not been programmed or if the recommended
tire pressures are not programmed. See your GM dealer
for service. Pressing any of the four DIC buttons, if
equipped, will clear the message from the DIC display.
If your vehicle is not equipped with the four DIC
buttons, pressing the trip odometer reset stem will clear
the message from the DIC display.
STABILITY SYS (System) ACTIVE
You may see the STABILITY SYS ACTIVE message on
the DIC. It means that an advanced computer-controlled
system has come on to help your vehicle continue to
go in the direction in which you are steering.
For more information on the StabiliTrak
®system, see
StabiliTrak®System on page 4-8.
STABILITY SYS (System) DISABLED
The STABILITY SYS DISABLED message will turn on
when you press the StabiliTrak®button, or when
the stability control has been automatically disabled.
There are four conditions that can cause this message
to appear.
One condition is overheating, which could occur if
StabiliTrak®activates continuously for an extended
period of time.
The message will also be displayed if the brake
system warning light is on. SeeBrake System
Warning Light on page 3-38.
The message could be displayed if the stability
system takes longer than usual to complete its
diagnostic checks due to driving conditions.
Also, if an engine or vehicle related problem has
been detected, and the vehicle needs service,
the message will appear. See your GM dealer.
The message will turn off as soon as the conditions that
caused the message to be displayed are no longer
present.
For more information on the StabiliTrak
®system, see
StabiliTrak®System on page 4-8.

Tire Pressure Monitor System
The Tire Pressure Monitor (TPM) system uses radio
and sensor technology to check tire pressure levels. If
your vehicle has this feature, sensors are mounted
on each tire and wheel assembly, except the spare tire.
The TPM sensors transmit tire pressure readings to
a receiver located in the vehicle.
When a low tire pressure condition is detected, the TPM
system will display the CHECK TIRE PRESSURE
warning message on the Driver Information
Center (DIC); and at the same time illuminate the low
tire pressure warning symbol. For additional information
and details about the DIC operation and displays,
seeDIC Operation and Displays on page 3-50andDIC
Warnings and Messages on page 3-53.
When the tire pressure
monitoring system warning
light is lit, one or more
of your tires is signicantly
under-inated.You should stop and check your tires as soon as
possible, and inate them to the proper pressure as
indicated on the vehicle’s tire information placard.
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. Each tire, including the spare, should be
checked monthly when cold and set to the
recommended ination pressure as specied in the
vehicle placard and owner’s manual.
The Tire and Loading Information label (tire information
placard) shows the size of your vehicle’s original
tires and the correct ination pressure for your vehicle’s
tires when they are cold. SeeInation - Tire Pressure
on page 5-65. For the location of the tire and loading
information label, seeLoading Your Vehicle on
page 4-44.
Your vehicle’s TPM system can alert you about a low
tire pressure condition but it does not replace normal tire
maintenance. SeeTire Inspection and Rotation on
page 5-69andTires on page 5-59.
Notice:Do not use a tire sealant if your vehicle is
equipped with Tire Pressure Monitors. The liquid
sealant can damage the tire pressure monitor
sensors.

TPM Sensor Identication Codes
Each TPM sensor has a unique identication code. Any
time you rotate your vehicle’s tires or replace one or
more of the TPM sensors, the identication codes
will need to be matched to the new tire/wheel position.
Each tire/wheel position is matched to a sensor, by
increasing or decreasing the tire’s air pressure.
The sensors are matched to the tire/wheel positions in
the following order: left front (LF); right front (RF);
right rear (RR) and left rear (LR).
You will have one minute to match the rst tire/wheel
position, and ve minutes overall to match all
four tire/wheel positions. If it takes longer than
one minute, 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 will need
to start over.
The TPM sensor matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to RUN with the engine off.
3. Turn the exterior lamp switch from the off position
to the on position four times within three seconds.
A double horn chirp will sound and the TPM low tire
warning light will begin to ash. The double horn
chirp and ashing TPM warning light indicate
that the TPM matching process has started.The TPM warning light should continue ashing
throughout the matching procedure. The SERVICE
TIRE MONITOR message will be displayed on
the Driver Information Center (DIC).
4. Start with the left (driver’s side) front tire.
5. Remove the valve cap from the valve cap stem.
Activate the TPM sensor by increasing or
decreasing the tire’s air pressure for 10 seconds,
then stop and listen for a single horn chirp.
The single horn chirp should sound within
15 seconds, conrming that the sensor identication
code has been matched to this tire and wheel
position. If you do not hear the conrming single
horn chirp, you will need to start over with step
number one. To let air-pressure out of a tire you can
use the pointy end of the valve cap, a pencil-style
air pressure gage or a key.
6. Proceed to the right (passenger’s side) front tire,
and repeat the procedure in Step 5.
7. Proceed to the right (passenger’s side) rear tire,
and repeat the procedure in Step 5.
8. Proceed to the left (driver’s side) rear tire, and
repeat the procedure in Step 5.
9. After hearing the conrming horn chirp for the left
rear tire, check to see if the TPM warning light is
still ashing. If yes, turn the ignition switch to LOCK.

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
The spare tire does not have a TPM sensor. If you
replace one of the road tires with the spare, the CHECK
TIRE PRESSURE message will be displayed on the
DIC screen. This message should go off once you
re-install the road tire containing the TPM sensor. The
SERVICE TIRE MONITOR message is displayed
when the TPM system is malfunctioning. One or more
missing or inoperable TPM sensors will cause the
service tire monitor message to be displayed. See your
dealer for service.
Federal Communications Commission and
Industry and Science Canada
The TPM system operates on a radio frequency subject
to Federal Communications Commission (FCC) Rules

Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your tires as
soon as possible and check wheel alignment. Also
check for damaged tires or wheels. SeeWhen It Is Time
for New Tires on page 5-71andWheel Replacement
on page 5-74for more information.
