System Interface

System Function

•	Blind-Spot Collision Warning (BCW) This system uses an audible warning and BCW signal on the mirror when sensing a vehicle in the blind spot area or when the vehicle is approaching at a high speed.

•	Blind-Spot Collision-Avoidance Assist (BCA) If a lane departure occurs, the BCA is immediately activated to perform differential braking on the front wheel on the opposite side.

•	Safe Exit Assist (SEA) When getting off the vehicle, SEA generates alarm to alert another vehicle approaching from the rear.

•	Rear Cross-Traffic Collision Warning (RCCW) When the vehicle is in reverse, the RCCW generates alarm to driver alert another vehicle is approaching from the rear.

•	Rear Cross-Traffic Collision-Avoidance Assist (RCCA) Warns the driver when it senses a vehicle approaching from the rear outer range while vehicle is in reverse (R) position. Collision avoidance assistance applies the brakes in the event of a collision risk.
