RCTA (Rear Crossing
Traffic Alert)*
The RCTA function uses the
BSM rear side radar sensors
installed behind the rear
bumper. This function is
intended to assist the driver in
checking areas that are not
easily visible when backing
up.
WARNING
■Cautions regarding the use of the system
The driver is solely responsible for safe driving. Always drive safely, tak-ing care to observe your surround-
ings.
The RCTA function is only a supple-
mentary function which alerts the driver that a vehicle is approaching from the right or left at the rear of the
vehicle.
As the RCTA function may not func-
tion correctly under certain conditions, the driver’s own visual confirmation of safety is necessary.
Over reliance on this function may lead to an accident resulting death or
serious injury.

RCD (Rear Camera
Detection)*
When the vehicle is backing
up, the rear camera detection
function can detect pedestri-
ans in the detection area
behind the vehicle. If a pedes-
trian is detected, a buzzer will
sound and an icon will be dis-
played on the multimedia dis-
play to inform the driver of the
pedestrian.
WARNING
■Cautions regarding the use of the system
The recognition and control capabili- ties for this system are limited.
The driver should always drive safely
by always being responsible without over relying on the system and have a understanding of the surrounding situ-
ations.
■To ensure the system can oper-
ate properly
Observe the following, otherwise there is the danger that could lead to
an accident.
