Ride Control Systems
Traction Control
System (TCS)
The vehicle has a Traction Control
System (TCS) that limits wheel spin.
The system utilizes engine and
braking controls to control wheel
spin during acceleration at all driving
speeds for maximum driver control
regardless of conditions. When the
system senses impending wheel slip
during acceleration, it signals the
throttle control to reduce drive wheel
torque. Under extreme situations,
such as going from pavement to ice
during acceleration, the system
will selectively apply the brakes to
maintain control. The system may
be heard or felt while it is working,
but this is normal.The TCS/StabiliTrak warning light
flashes when the traction control
system is limiting wheel spin.
The StabiliTrak/TCS warning light
comes on solid if there is a problem
with the traction control system.
SeeTraction Control System
(TCS)/StabiliTrak
®Light on
page 4-24for more information.
If the light stays on, see your
dealer/retailer for service. When the
TCS/StabiliTrak warning light is on,
the system will not limit wheel spin.
Adjust your driving accordingly.
TCS automatically comes on
whenever the vehicle is started.
To limit wheel spin, especially in
slippery road conditions, the systemshould always be left on, but it may
be necessary to turn the system off if
the vehicle is stuck in sand, mud or
snow and rocking the vehicle is
required. Also, turn TCS off while
in deep snow or on loose gravel,
to assist vehicle motion at lower
speeds. SeeIf the Vehicle is Stuck
on page 8-11for more information.
See alsoWinter Driving on
page 8-10for information on using
TCS when driving in snowy or icy
conditions.
To turn the system off, press
and release the StabiliTrak/TCS
button located on the console
in front of the shift lever.
8-34 Driving and Operating
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
