The StabiliTrak system or the Traction Control System (TCS) indicator/warning light comes on briefly while starting the engine.
If it does not, have the vehicle serviced by your dealer/retailer.
If the system is working normally the indicator light will then go off.
The indicator/warning light flashes while the StabiliTrak or TCS system is working to control the vehicle on a low traction surface.
If the TCS indicator/warning light comes on and stays on while driving, the vehicle needs service.
