When the system is on and the parking brake is fully
released, this warning light will also come on to let you
know if there is a problem.
When this warning light is on, the system will not limit
wheel spin. Adjust your driving accordingly.
To limit wheel spin, especially in slippery road
conditions, you should always leave the Traction
Control System on. But you can turn the system off
if you prefer.

This light will come on
briefly when the ignition is
turned to ON along
with the anti-lock brake
system warning light.
To turn the system on or
off, press the TCS button
located on the console
below the shift lever.
If the Traction Control System is limiting wheel spin
when you press the button to turn the system off, the
warning light will come on, but the system will not
turn off right away. It will wait until there is no longer a
current need to limit wheel spin.
You can turn the system back on at any time by
pressing the button again. The Traction Control System
warning light should go off.
Adding non-GM accessories can affect your vehicle's
performance. See Accessories and Modifications

When you turn the system
off, the Traction Control
Off light will come on
and stay on.
