The StabiliTrak® light comes on briefly as the engine is started. If it does not come on have the vehicle serviced by your dealer/retailer.
This light flashes while the StabiliTrack or the Traction Control System (TCS) is working. The light comes on when the ESP has been turned off and if there is a problem with the StabiliTrak or the TCS. See Traction Control System (TCS) and StabiliTrak® System for more information.
