StabiliTrak comes on automatically whenever the vehicle is started. To assist with directional control of the vehicle, the system should always be left on. When StabiliTrak activates, d flashes on the instrument panel. A noise may be heard or vibration may be felt in the brake pedal. This is normal. Continue to steer the vehicle in the intended direction. See Traction Control System (TCS)/ StabiliTrak® Light on page 5‑21 for more information.
