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 422
. 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.
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 811
for
more information. See also Winter
Driving
on page 89
for
information on using TCS when
driving in snowy or icy conditions.
