SERVICE THEFT SYSTEM
This message displays if there is a problem with
the theft-deterrent system programmed in the key.
A fault has been detected in the system which
means that the system is disabled and it is
not protecting the vehicle. The vehicle usually
restarts; however, you may want to take the
vehicle to your dealer before turning off the engine.
SeeKeys on page 84for information on the
PASS-Key
®III system.
This message displays only while the ignition is in
RUN. A chime sounds for two seconds while
this message is displayed. Press the set/reset
button to acknowledge this message and to clear
it from the screen.
This message continues to display if it has not
been acknowledged when the engine is turned off.
It also re-displays for three seconds if the
message has been acknowledged, but the
condition still exists when the engine is turned off.
If the condition still exists, the message
re-appears when the engine is turned on.
SERVICE TIRE MONITOR SYSTEM
This message displays if a part on the Tire
Pressure Monitor (TPM) system is not working
properly. If you drive your vehicle while any of the
four sensors are missing or inoperable, the
warning comes on in about 20 minutes. A sensor
would be missing, for example, if you put
different wheels on your vehicle without
transferring the sensors. If the warning comes on
and stays on, there may be a problem with the
TPM. See your dealer.
This message displays only while the ignition is in
RUN. Press the set/reset button to acknowledge

How to Check
Use a good quality pocket-type gage to check tire
pressure. You cannot tell if your tires are
properly inated simply by looking at them. Radial
tires may look properly inated even when they
are under-inated. Check the tire’s ination
pressure when the tires are cold. Cold means your
vehicle has been sitting for at least three hours
or driven no more than 1 mile (1.6 km).
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. If your vehicle has this feature, sensors
are mounted onto each tire and wheel assembly,
except for the spare tire. The TPMS sensors
monitor the air pressure in your vehicle’s tires and
transmit tire pressure readings to a receiver
located in the vehicle.
When a low tire pressure condition is detected,
the TPMS will illuminate the low tire pressure
warning symbol on the instrument panel cluster,
and at the same time a warning message to check
the pressure in a specic tire displays on the
Driver Information Center (DIC). The low
tire pressure warning light and the DIC warning
message CHECK TIRE PRESSURE come
on at each ignition cycle until the tires are inated
to the correct ination pressure.

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 ash 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, including the
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.
A Tire and Loading Information label, attached to
your vehicle, 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 317, for an
example of the Tire and Loading Information
label and its location on your vehicle. Also see
Ination - Tire Pressure on page 408.
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 414andTires on
page 400.
Notice:Do not use a tire sealant if your
vehicle has Tire Pressure Monitors. The liquid
sealant can damage the tire pressure monitor
sensors.
The TPMS will not function properly if one or more
of the TPMS sensors are missing or inoperable.
If the system detects a missing or inoperable
sensor, an error message SERVICE TIRE
MONITOR SYSTEM appears on the DIC display.
If you have replaced a tire/wheel assembly
without transferring the TPMS sensors, the error
message displays. Once you re-install the
TPMS sensors, the error message should go off.
See your dealer for service if all TPMS sensors
are installed and the error message comes on and
stays on.

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.

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 chirps two more
times to signal the tire learning process
has ended. Turn the ignition switch to 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.
The spare tire does not have a TPMS sensor.
If you replace one of the road tires with the spare,
the SERVICE TIRE MONITOR SYSTEM
message will be displayed on the DIC. This
message should go off once you re-install the road
tire containing the TPMS sensor.Federal Communications Commission

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.
After temporarily repairing a tire using the tire
inator kit, it is recommended to take your vehicle
to an authorized GM dealer within 100 miles
(161 kilometers) of driving to have the tire
inspected and repaired. If the sealant isn’t
removed from the tire within a 100 miles
(161 kilometers) of driving, it is more likely
that the tire and tire pressure monitoring sensor
may get damaged and have to be replaced.Accessing the Tire Inator Kit
To access the tire inator kit, do the following:
1. Open the trunk. SeeTrunk on page 96
for more information.
2. Locate the tire inator kit by lifting up the
carpet.
3. Remove the inator
kit cover by turning
the center nut
counterclockwise.
