GMC Terrain: Warning Lights, Gauges, and Indicators / Traction Control System (TCS)/StabiliTrak Light

This light comes on briefly when the
engine is started.
If the light does not come on, have
the vehicle serviced by your dealer.
If the system is working normally,
the indicator light turns off.
If the light is on and not flashing, the
TCS and potentially the StabiliTrak/
ESC system have been disabled.

DIC messages to determine which
feature(s) is no longer functioning
and whether the vehicle requires
service.

TCS and/or the StabiliTrak/ESC
