DrIver assIstance systems
The driver assistance systems use advanced technologies to help avoid collisions by
providing visual and audible alerts under some imminent collision conditions.
Forward Collision AlertF – When approaching a vehicle directly ahead too quickly, the system flashes a visual alert and pulses the Safety Alert SeatF. See Safety Alert Seat.
The Vehicle Ahead indicator will illuminate in green on the instrument cluster when a vehicle is detected and will illuminate in amber when following a vehicle ahead too closely. If your vehicle approaches another vehicle too rapidly, the will flash, six red lights will flash on the windshield and the Safety Alert SeatF will pulse. See Safety Alert Seat.
Press the Collision Alert button on the left side of the steering wheel to set the alert sensitivity to Far, Medium, Near, or Off. The setting is displayed in the Driver Information Center.
Lane Departure WarningF – When crossing a detected lane marking without using a turn signal, the system flashes an amber visual alert on the instrument cluster and pulses the left or right side of the Safety Alert SeatF. See Safety Alert Seat.
Press the Lane Departure Warning button on the center of the instrument panel to turn the system on or off.
Safety Alert SeatF – The driver’s seat pulses, left side, right side, or simultaneously, to alert the driver of potential hazards.

setting, go to Settings > Vehicle > Collision/Detection > Alert Type.
