A buzzer (intermittent) sounds to indicate that VSC is operating. The stop lights and high mounted stoplight turn on when the hillstart assist control system is operating. 2 When driving To disable TRAC and/or VSC If the vehicle gets stuck in fresh snow or mud, TRAC and VSC may reduce power from the engine to the wheels.
