®System on page 284for more
information.
If this message turns on while you are driving, pull
off the road as soon as possible and stop carefully.
Try resetting the system by turning the ignition off
and then back on. If this message still stays on or
turns back on again while you are driving, your
vehicle needs service. Have the StabiliTrak
®
System inspected by your dealer as soon as
possible.
SERVICE SUSPENSION SYSTEM
This message displays to indicate that the
suspension system is not operating properly.
See your dealer for service.
SERVICE THEFT SYSTEM
This message displays when 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. See
PASS-Key
®III+ on page 111for more information.
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.
228
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 398andTires on page 385.
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 will be shown on the DIC
display. If you have replaced a tire/wheel assembly
without transferring the TPMS sensors, the error
message will be displayed. Once you re-install the
TPMS sensors, the error message should go
off. See your GM dealer for service if all TPMS
sensors are installed and the error message
comes on and stays on.Resetting the TPMS Sensor
Identi cation Codes
Each TPMS sensor has a unique identi cation
code. Any time you replace one or more of
the TPMS sensors or rotate the vehicle’s tires, the
identi cation codes will need to be matched to
the new tire/wheel position. The sensors are
matched, to the tire/wheel positions, in the
following order: driver’s side front tire, passenger’s
side front tire, passenger’s side rear tire, and
driver’s side rear tire using a TPMS diagnostic tool.
See your GM 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 in ation
pressure indicated on the tire’s sidewall.
You will have two minutes to match each tire and
wheel position. If it takes longer than two minutes to
match any tire and wheel position, or more than
ve minutes to match all four tire and wheel
positions the matching process stops and you will
need to start over.
396
The TPMS matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to RUN with the
engine off.
3. Using the DIC, press the vehicle information
button until the LEARN TIRE POSITIONS
message displays.
4. Press the set/reset button to allow the system
to learn the tire positions. The horn will sound
twice to indicate the receiver is ready, and
the TIRE LEARNING ACTIVE message
will display. The TPMS system is ready for
the sensor matching process to begin.
5. Start with the driver’s side front tire.
6. Remove the valve cap from the tire’s valve
stem. Activate the TPMS sensor by increasing
or decreasing the tire’s air pressure for
ve seconds, or until a horn chirp sounds.
The horn chirp, which may take up to
30 seconds to sound, con rms that the
sensor identi cation 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.7. Proceed to the passenger’s side front tire, and
repeat the procedure in Step 6.
8. Proceed to the passenger’s side rear tire, and
repeat the procedure in Step 6.
9. Proceed to the driver’s side rear tire, and
repeat the procedure in Step 6.
10. After hearing the con rming horn chirp for the
driver’s side rear tire, the tire learning process
ends. Turn the ignition switch to OFF.
11. Set all four tires to the recommended air
pressure level as indicated on the tire and
loading information label.
12. Put the valve caps back on the valve stems.
The compact spare tire and wheel assembly
does not have a TPMS sensor. If you replace
one of the road tires with the compact spare tire,
the SERVICE TIRE MONITOR SYSTEM
message will be displayed on the DIC display
screen. This message should go off once
you re-install the road tire containing the
TPMS sensor.
397
When rotating your tires, always use the correct
rotation pattern shown here.
Do not include the compact spare tire in your tire
rotation.
After the tires have been rotated, adjust the
front and rear in ation pressures as shown
on the Tire and Loading Information label. See
In ation - Tire Pressure on page 392andLoading
Your Vehicle on page 307.Reset the Tire Pressure Monitor System. See
“TPMS Sensor Identi cation Codes” under
Tire Pressure Monitor System on page 393.
Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Speci cations on page 436.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after time. The wheel could
come off and cause an accident. When
you change a wheel, remove any rust or
dirt from places where the wheel attaches
to the vehicle. In an emergency, you can
use a cloth or a paper towel to do this;
but be sure to use a scraper or wire brush
later, if needed, to get all the rust or dirt
off. SeeChanging a Flat Tire on page 408.
399
When the CHANGE ENGINE OIL SOON message
appears, certain services, checks, and inspections
are required. Required services are described
in the following for “MaintenanceI” and
“MaintenanceII.” Generally, it is recommended
that your rst service be MaintenanceI, your
second service be MaintenanceII, and that you
alternate MaintenanceIand MaintenanceII
thereafter. However, in some cases,
MaintenanceIImay be required more often.MaintenanceI— Use MaintenanceIif the
CHANGE ENGINE OIL SOON message comes on
within 10 months since the vehicle was purchased
or MaintenanceIIwas performed.
MaintenanceII— Use MaintenanceIIif the
previous service performed was MaintenanceI.
Always use MaintenanceIIwhenever the message
comes on 10 months or more since the last
service or if the message has not come on at all
for one year.
