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 alerting 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.

your eyes when driving.
The 360°View Monitor is an auxiliary device which assists the driver in checking the safety of
the area around the vehicle.
The shooting range of the cameras and detection range of the sensors are limited. For
example, the areas in black at the front and rear of the vehicle image and the seams where
each of the camera images merge are blind spots where an obstruction may not be visible. In
addition, the extended vehicle width lines and pr ojected vehicle path lines are only to be used
as references, and the images on the screen may differ from the actual conditions.
