Traction Control System (TCS)
Warning Light
This light should come on
briefly when you start the
engine. If it stays on or
comes on while you
are driving, there is a
problem with your traction
control system.
The traction control system warning light comes on for a
few seconds when the ignition is turned to ON. It will
come on again when you press the TRAC OFF button to
turn off the traction control system. See Traction
Control System (TCS) on page 4-9 for more information.
In the following cases, contact your dealer:
• The indicator light does not come on when the
ignition is turned to ON.
• The indicator light remains on after the ignition is
turned ON.
• The indicator light comes on with the normal driving
mode while driving.

Indicator Light
This light warns that there
is a problem somewhere in
the traction control system
or the vehicle stability
control (VSC) system.
The light will come on when the ignition is turned to ON
and will go off after a few seconds.
If the light comes on while driving, the system does not
work. However, as conventional braking operates
when applied, there is no problem to continue driving.
In the following cases, contact your GM dealer:
• The warning light does not come on after the
ignition is turned to ON.
• The warning light remains on after the ignition is
turned to ON.
• The warning light comes on while driving.
The traction control system light will come on when the
VSC warning light comes on, even if the TRAC OFF
button is not pressed.
See Traction Control System (TCS) on page 4-9 for
