Traction Control System (Tcs) - Pontiac 2004 Grand Prix Owner's Manual

Traction Control System (TCS)

If your vehicle has the 3800 supercharged V6 engine
it has a traction control system that limits wheel
spin. This is especially useful in slippery road conditions.
The system operates only if it senses that one or both
of the front wheels are spinning or beginning to lose
traction. When this happens, the system works the front
brakes and reduces engine power to limit wheel spin.
You may feel or hear the system working, but this is
normal.

This symbol will appear on
the DIC screen when the
system is active, along with
the TRACTION CONTROL
ACTIVE message.
When the traction control
system is not working, this
symbol will appear on the
instrument panel cluster.
When these symbols and messages appear on the
instrument panel and the Driver's Information Center
(DIC), the system will not limit wheel spin. Adjust your
driving accordingly.
The traction control system automatically comes on
whenever you start your vehicle. To limit wheel spin,
especially in slippery road conditions, you should always
leave the system on. But you can turn the traction
control system off if you ever need to. You should turn
the system off if your vehicle ever gets stuck in
sand, mud or snow and rocking the vehicle is required.
See "Rocking Your Vehicle to Get It Out" under
If You Are Stuck: In Sand, Mud, Ice or Snow on
page 4-32 .
This symbol, along with
the message TRACTION
CONTROL OFF will
also display in the DIC
for three seconds when
the traction control system
is not active.
