If none of the above have made the light turn off, your
dealer/retailer can check the vehicle. The dealer/retailer
has the proper test equipment and diagnostic tools to
x any mechanical or electrical problems that might have
developed.
Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
might begin programs to inspect the emission control
equipment on the vehicle. Failure to pass this inspection
could prevent getting a vehicle registration.
Here are some things to know to help the vehicle pass
an inspection:
The vehicle will not pass this inspection if the check
engine light is on with the engine running.
To perform a check engine light bulb check with the
keyless ignition, make sure the transmitter fob is in
the passenger compartment. SeeIgnition Positions
on page 2-26. Press the bottom of the Acc. button on
the instrument panel and hold the button down forve seconds. The instrument panel, including the
check engine light, will light up and the ignition will be
on, but the engine will not start — press the bottom of
the Acc. button only briey, less than ve seconds,
the accessory power mode will be turned on, but not
the ignition. After the bulb check, press and release
the Acc. button again to turn the ignition off and avoid
draining the vehicle’s battery.
The vehicle will not pass this inspection if the OBD II
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen
if the battery has recently been replaced or if the
battery has run down. The diagnostic system is
designed to evaluate critical emission control
systems during normal driving. This can take several
days of routine driving. If this has been done and the
vehicle still does not pass the inspection for lack of
OBD II system readiness, your dealer/retailer can
prepare the vehicle for inspection.

STABILITY COMPETITIVE MODE
If your All-Wheel Drive (AWD) vehicle has the Active
Steering with Enhanced StabiliTrak option, this message
displays when the Competitive Mode for stability control
has been turned on using the TC (traction control) button.
SeeEnhanced StabiliTrak
®on page 4-6for more
information. When the Enhanced StabiliTrak Competitive
Mode has been activated, traction control operates in
competitive mode and cannot be turned off. Also, the
Active Steering and the Magnetic Ride Control systems
operate in the Performance Mode. For more information,
see “Active Steering and Magnetic Ride Control” in the
Index in the Navigation manual.
STABILITY SECURE MODE
If your All-Wheel Drive (AWD) vehicle has the Active
Steering with Enhanced StabiliTrak option, this message
displays when the stability control system is in the
secure mode. Stability Secure Mode is set automatically
when certain system faults or vehicle conditions are
detected. When the Stability Secure Mode is activated,
the stability control system will not respond to driver
requests to change the stability mode until the next
ignition cycle or until the vehicle condition or fault
is returned to normal. SeeEnhanced StabiliTrak
®
on page 4-6for more information.
STABILITY SYS (System) ACTIVE
This message displays any time the StabiliTrak system
or Enhanced StabiliTrak system is actively assisting
with directional control of the vehicle. Slippery road
conditions may exist when this message is displayed,
so adjust your driving accordingly. This message
may stay on for a few seconds after StabiliTrak
stops assisting with directional control of the vehicle.
SeeStabiliTrak
®System on page 4-6orEnhanced
StabiliTrak®on page 4-6for more information.
STABILITY SYS (System) NOT READY
This message displays if the StabiliTrak system is
not ready. Two conditions may cause this message
to display:
The vehicle needs to be driven in a straight line
until the sensors are centered. Once the sensors
are centered, the StabiliTrak system is ready
and the STABILITY SYS READY message displays.
The system needs to warm up. This may occur
when rst starting your vehicle and driving away
during cold winter weather. This is normal.
To acknowledge this message, press the
reset button.
The StabiliTrak performance is affected until the
STABILITY SYS READY message is displayed in the

Stability control activates when the computer senses a
difference between the intended path and the direction
the vehicle is actually traveling. Stability control
automatically adjusts the front road wheel steering
angle, modies the suspension stiffness, and selectively
applies braking pressure at any one of the vehicle’s
brakes to help maintain directional control of the vehicle.
When the system activates, a STABILITY SYS
ACTIVE message displays on the Driver Information
Center (DIC). SeeDIC Warnings and Messages
on page 3-79. It is normal to hear a noise or feel
vibration in the brake pedal when the system is working.
Continue to steer the vehicle in the intended direction.
If cruise control is engaged when Enhanced StabiliTrak
activates, the cruise control will automatically disengage.
Cruise Control may be re-engaged when road conditions
allow. SeeCruise Control on page 3-16,orAdaptive
Cruise Control on page 3-20for more information.
Enhanced StabiliTrak comes on automatically in the
Stability Touring Mode, when the vehicle is started.
The Stability Touring Mode is recommended for normal
driving. Enhanced StabiliTrak also has Stability
Competitive Mode that is turned on by pressing the
Traction Control (TC) button twice quickly. This mode is
designed to be used by the performance consciousdriver who desires less stability control intervention.
SeeCompetitive Driving Mode on page 4-11. When the
Stability Control Competitive Mode has been activated,
traction control operates in competitive mode and
cannot be turned off. The STABILITY COMPETITIVE
MODE message will be displayed on the DIC.
SeeDIC Warnings and Messages on page 3-79.
When operating the vehicle in the Stability Competitive
Mode, the system provides less stability control
intervention. Driving should be adjusted accordingly.
When the Stability Competitive Mode has been selected,
the Active Steering and Magnetic Ride Control Touring
Mode is not available. These systems are automatically
changed to the Performance Mode, providing more
response to road conditions and quicker steering
response. For more information, see “Active Steering
and Magnetic Ride Control Mode” in the Index of
the vehicle’s Navigation Manual.
To assist with directional control of the vehicle, always
leave the system on. Stability control can be turned
off however, by using the TC button. SeeTraction
Control System (TCS) on page 4-10. The STABILITY
SYS OFF message will be displayed on the DIC.
SeeDIC Warnings and Messages on page 3-79.

Engine Oil Additives / Engine Oil
Flushes
Do not add anything to the oil. The recommended oils
with the starburst symbol that meet GM standards are all
you need for good performance and engine protection.
Engine oil system ushes are not recommended
and could cause engine damage not covered by
the vehicle warranty.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system that lets you
know when to change the engine oil and lter. This is
based on engine revolutions and engine temperature,
and not on mileage. Based on driving conditions, the
mileage at which an oil change will be indicated can vary
considerably. For the oil life system to work properly, you
must reset the system every time the oil is changed.Notice:If your vehicle is an STS-V model, the
engine uses a special oil lter. The use of any
other engine oil lter could lead to lter failure and
result in severe engine damage. Damage caused
by use of the wrong engine oil lter would not
be covered by your new vehicle warranty.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is necessary.
A CHANGE ENGINE OIL SOON message in the DIC
will come on. SeeDIC Warnings and Messages on
page 3-79. Change the oil as soon as possible within the
next 600 miles (1 000 km). It is possible that, if you are
driving under the best conditions, the oil life system might
not indicate that an oil change is necessary for over a
year. However, the engine oil and lter must be changed
at least once a year and at this time the system must be
reset. Your dealer/retailer has trained service people who
will perform this work using genuine parts and reset the
system. It is also important to check the oil regularly and
keep it at the proper level.
If the system is ever reset accidentally, you must
change the oil at 3,000 miles (5 000 km) since the
last oil change. Remember to reset the oil life system
whenever the oil is changed.

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 your vehicle’s tires, the identication 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 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 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. If using this method to match TPMS
sensors, the complete procedure outlined below must
be performed within 15 minutes of the vehicle being
stationary.
To decrease air-pressure out of a tire you can use the
pointed end of the valve cap, a pencil-style air pressure
gage, or a key.
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/wheel positions, the matching
process stops and you will need to start over.The TPM matching process is outlined below:
1. Set the parking brake.
2. Press the push-button ignition switch to Acc.
3. Using the keyless access transmitter, lock and
unlock the vehicle’s doors.
4. Press the lock and unlock buttons, at the same
time, on the keyless access transmitter. The horn
sounds twice, indicating that the TPMS is ready,
and the sensor matching process can begin.
5. Start with the driver side front tire.
6. Remove the valve cap from the 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,
conrms that the sensor identication code
has been matched to this tire position.
7. Proceed to the passenger side front tire, and repeat
the procedure in Step 6.
8. Proceed to the passenger side rear tire, and repeat
the procedure in Step 6.
9. Proceed to the driver side rear tire, and repeat the
procedure in Step 6.
10. After hearing the conrming single horn chirp for the
driver side rear tire, a double horn chirp will sound to
signal the tire matching mode is no longer active.
Press the push-button ignition switch to Acc.
