When the VSC/TRAC or Active TRAC/hill-start assist control systems are operating
If the vehicle is in danger of slip- ping or rolling backward when starting on an incline, or if any of the drive wheels spins, the slip indi- cator light flashes to indicate that the VSC/TRAC or Active TRAC/ hill-start assist control systems are operating.
A buzzer (intermittent) sounds to indicate that VSC is operating.
The stop lights and high mounted stoplight turn on when the hill-start assist control system is operating.
