Rear Cross Traffic Alert (RCTA)*
The RCTA system is designed to assist the driver in checking the area to the rear of the
vehicle on both sides while the vehicle is reversing by alertin g the driver to the presence of
vehicles approaching the rear of the vehicle.
The RCTA system detects vehicles approaching from the rear left and right sides of the
vehicle, and the rear of the vehicle while the vehicle is being reversed out of a parking
space, and notifies the driver of possible danger using the Blind Spot Monitoring (BSM)
warning indicator lights and the warning buzzer.
