Ride Control Systems
Traction Control

System (TCS)

The vehicle has a traction
control system that limits wheel
spin. This is especially useful in
slippery road conditions. On a
front-wheel-drive vehicle, the
system operates if it senses that
one or both of the front wheels
are spinning or beginning to lose
traction. On an All-Wheel-Drive
(AWD) vehicle, the system will
operate if it senses that any of the
wheels are spinning or beginning
to lose traction. When this happens,
the system brakes the spinning
wheel(s) and/or reduces engine
power to limit wheel spin.
The system may be heard or felt
while it is working, but this is
normal.
The TCS/StabiliTrak warning light
flashes to indicate that the traction
control system is active.
This warning light comes on if there
is a problem with the traction control
system.
See Traction Off Light on page 5 21.
When this warning light is on, the
system does 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 system
should always be left on. But,
TCS can be turned off if needed.
Notice: Do not repeatedly brake
or accelerate heavily when TCS is
off. The vehicle's driveline could
be damaged.
I n f o r ma t i o n P r o v i d e d b y :
The TCS off light comes on to
indicate that the traction control
system has been turned off.
When TCS is switched off on AWD
vehicles, the system may still make
noise. This is normal and necessary
with the AWD hardware on the
vehicle.
It might be necessary to turn the
system off if the vehicle gets stuck
in sand, mud or snow and rocking
the vehicle is required. See If the
Vehicle is Stuck on page 9 11 for
more information. See also Winter
Driving on page 9 9 for information
on using TCS when driving in snowy
or icy conditions.
