Traction Off Light

This light comes on briefly while starting the engine. If it does not, have the vehicle serviced by your dealer.
This light comes on when the Traction Control System (TCS) has been turned off by pressing and releasing the TCS/StabiliTrak button.
This light also comes on and the system turns off if there is a problem with the traction control system.
If the light comes on and stays on for an extended period of time while the system is turned on, the vehicle needs service.
See Traction Control System (TCS) and StabiliTrak® System for more information.
