Traction Control System (Tcs) - Chevrolet 2008 Impala Owner's Manual

Traction Control System (TCS)

Your vehicle may have a Traction Control System (TCS)
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 reduces engine power and may
also upshift the transmission and apply the front brakes
to limit wheel spin.
You may feel or hear the system working, but this is
normal.
If your vehicle is in cruise control when the TCS begins
to limit wheel spin, the cruise control will automatically
disengage. When road conditions allow you to safely
use it again, the cruise control can be re-engaged.
See Cruise Control on page 3-10.
4-6
This light will flash
when the TCS is limiting
wheel spin.
The TCS operates in all transmission shift lever
positions. But the system can upshift the transmission
only as high as the shift lever position chosen, so
use the lower gears only when necessary. See
Automatic Transmission Operation on page 2-26.
A SERVICE TRACTION CONTROL message also
appears on the DIC. When this warning light is on, the
system will not limit wheel spin. Adjust your driving
accordingly. See DIC Warnings and Messages
on page 3-52 for more information.
To limit wheel spin, especially in slippery road
conditions, you should always leave the TCS on.
But you can turn the system off if you ever need to.
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 on
page 4-20 and If Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow on page 4-20 for more information.
When the system is on,
this warning light comes
on and stays on to let
you know if there is
a problem.
