Ride Control Systems

Traction Control/
Electronic Stability
Control
System Operation
The vehicle has a Traction Control
System (TCS) and an Electronic
Stability Control (ESC) system.
These systems help limit wheel slip
and assist the driver in maintaining
control, especially on slippery road
conditions.
TCS activates if it senses that 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.
ESC activates when the vehicle
senses a difference between the
intended path and the direction the
vehicle is actually traveling. ESC
selectively applies braking pressure
to any one of the vehicle wheel
brakes to assist the driver in
keeping the vehicle on the
intended path.
If cruise control is being used and
TCS or 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 on
page 9-9 and Turning the Systems
Off and On later in this section.
Driving and Operating
The indicator light for both systems
is in the instrument cluster. This
light will:
Flash when TCS is limiting
wheel spin.
Flash when ESC is activated.
Turn on and stay on when either
system is not working.
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. The vehicle is
safe to drive, but driving should be
adjusted accordingly.
