Stability Control

System Operation
The vehicle has a Traction Control
System (TCS) and StabiliTrak/
Electronic Stability Control (ESC).
These systems help limit wheel spin
and assist the driver in maintaining
control, especially on slippery road
conditions.
TCS activates if it senses any of the
drive wheels are spinning or beginning
to lose traction. When this happens,
TCS applies the brakes to the spinning
wheels and reduces engine power to
limit wheel spin.
StabiliTrak/ESC activates when the
vehicle senses a difference between
the intended path and the direction
the vehicle is actually traveling.
StabiliTrak/ESC selectively applies
braking pressure to one or more of the
vehicle wheel brakes to assist the
driver in keeping the vehicle on the
intended path. Trailer Sway Control
(TSC) is also on automatically when
the vehicle is started. See Trailer Sway
Control (TSC) 0 338.
If cruise control is being used and
traction control or StabiliTrak/ESC
begins to limit wheel spin, cruise
control will disengage. Cruise control
may be turned back on when road
conditions allow.
Both systems come on automatically
when the vehicle is started and begins
to move. The systems may be heard or
felt while they are operating or while
performing diagnostic checks. This is
normal and does not mean there is a
problem with the vehicle.
It is recommended to leave both
systems on for normal driving
conditions, but it may be necessary to
turn TCS off if the vehicle gets stuck
in sand, mud, ice, or snow. See If the
Vehicle Is Stuck 0 236 and Turning
the Systems Off and On later in this
section.
When the transfer case (if equipped)
is in Four-Wheel Drive Low, the TCS
and StabiliTrak/ESC are automatically
disabled,
comes on, and the
appropriate message will appear on
the Driver Information Center (DIC).
The indicator light for both systems is
to the right of the center stack and
below the screen. This light will:
Flash when TCS is limiting
wheel spin
Flash when StabiliTrak/ESC is
activated
Turn on and stay on when either
system is not working
See Traction Control System (TCS)/
StabiliTrak Light 0 123.
If either system fails to turn on or to
activate, a message displays in the
Driver Information Center (DIC), and
comes on and stays on to indicate
that the system is inactive and is not
assisting the driver in maintaining
control. Adjust driving accordingly.
