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. A Driver Information Center (DIC) message may display. Check the DIC messages to determine which feature(s) is no longer functioning and whether the vehicle requires service.
If the light is on and flashing, the TCS and/or the StabiliTrak/ESC system is actively working.
See Traction Control/Electronic Stability Control.

makes the wait-to-start light stay on
for a shorter amount of time than
most diesel engines...
