The system applies the brakes to slow the
vehicle to maintain a safe distance from
the vehicle in front. The system applies
only limited maximum braking. Press the
brake pedal to override the system.
If the system predicts that its maximum
braking level is insufficient, an audible
warning sounds while the system
continues to brake. A red warning bar
appears on the windshield heads-up

stop the vehicle.
The system may provide slight temporary
acceleration when you use your driver side
directional indicator while following a lead
vehicle, to aid in passing the vehicle.
