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 rear-wheel-drive vehicle, the system
operates if it senses that one or both of the rear 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.
This warning light comes
on if there is a problem
with TCS.
See Traction Control System (TCS) Warning Light on
page 3-63. When this 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 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.
When TCS is switched off on AWD and STS-V vehicles,
the system may still be working. This is normal and
necessary with the hardware on the vehicle.
It may be necessary to turn the system off if the vehicle
gets stuck in sand, mud or snow and rocking the vehicle
is required. See Rocking Your Vehicle to Get It Out on
page 4-24 and If Your Vehicle is Stuck in Sand, Mud, Ice,
or Snow on page 4-23 for more information. See Winter
Driving on page 4-21 for information on using TCS when
driving in snowy or icy conditions.
