Traction Control System (TCS)/StabiliTrak® Light

The TCS/StabiliTrak light comes on briefly when the engine is started.
If the light does not come on or stays on, have the vehicle serviced by the dealer. If the system is working normally, the indicator light turns off.
If the light comes on and stays on while driving, and a message displays in the Driver Information Center (DIC), have the vehicle serviced by the dealer. See Ride Control System Messages on page 5‑47 for more information.
If the light flashes while driving, this means that StabiliTrak or TCS is assisting in controlling the vehicle.
See StabiliTrak® System on page 9‑59 for more information.
