StabiliTrak comes on automatically
whenever the vehicle is started.
The system should be left on to
help assist with directional control
of the vehicle. If StabiliTrak needs
to be turned off, press and hold the
StabiliTrak/TCS button until theTraction Control Off light and the
StabiliTrak Off light come on the
instrument panel cluster. If the
system has been turned off, press
and release the StabiliTrak/TCS
button to turn the system back on.
Engine Drag Control (EDC)
EDC improves vehicle stability by
sensing if there is difference in speed
between the free rolling front wheels
and the rear drive wheels that often
occurs when the driver takes their
foot off the accelerator pedal on
slippery surfaces (snow, ice, etc.).
When this is detected, EDC sends
more torque to the rear wheels to
make sure all four wheels are
spinning at similar speeds, making
the vehicle more stable.
Competitive
Driving Mode
On vehicles with a V8 engine,
the driver can select this optional
handling mode by pressing the
StabiliTrak/TCS button two times
quickly while Traction Control and
StabiliTrak are turned on. When
the system is on, the StabiliTrak
Off light comes on and StabiliTrak
Competitive Mode will be displayed
in the Driver Information Center
(DIC). SeeRide Control System

TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. Any time you
replace one or more of the TPMS
sensors or rotate your vehicle’s tires,
the identification 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/retailer for service.
The TPMS sensors can also be
matched to each tire/wheel position
by increasing or decreasing the
tire’s air pressure. If increasing the
tire’s air pressure, do not exceed
the maximum inflation pressure
indicated on the tire’s sidewall.
To decrease the tire’s air-pressure
use the pointed end of the valve
cap, a pencil-style air pressure
gage, or a key.You have two minutes to match
the first tire/wheel position, and
five minutes overall, to match all
four tire/wheel positions. If it takes
longer than two minutes, to match
the first tire and wheel, or more than
five minutes to match all four tire
and wheel positions, 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
ON/RUN with the engine off.
3. Go to the TPM vehicle
information screen on the DIC.
SeeDriver Information Center
(DIC) on page 4-27. Press set to
relearn the sensors. The horn
sounds twice to signal the
receiver is in relearn mode and
Tire Learning Active message
displays on the DIC screen.
4. Start with the driver side
front tire.5. Remove the valve cap from
the valve stem. Activate the
TPMS sensor by increasing or
decreasing the tire’s air pressure
for 10 seconds, or until a horn
chirp sounds. The horn chirp,
which can take up to 30 seconds
to sound, confirms that the TPMS
sensor identification code has
been matched to this tire position.
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 confirming horn
chirp, for the driver side rear tire,
the horn sounds two more times
to signal the tire learning mode is
no longer active. Turn the ignition
switch to LOCK/OFF.
