If a vehicle approaching from the
right or left at the rear of the vehicle
is detected, the RCTA icon

When the RCTA is off, “Rear Cross
Traffic Alert OFF” will be displayed

RCTA (Rear Cross Traf-
fic Aler t) function*
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,
taking care to o bserve your sur-
roundings. The RCTA function is
only a supplementary function
which alerts the driver that a vehi-
cle is approaching from the right
or left at the rear of the vehicle. As
the RCTA function may not func-
tion correctly under certain condi-
tions, the driver’s own visual
confirmation of safety is neces-
sary. Over relia nce on this func-
tion may lead to an accident
resulting death or serious injury.

Safe Exit Assist*
The safe exit assist is a sys-
tem that uses rear side
radar sensors installed on
the inner side of the rear
bumper to help occupants
judge if an approaching
vehicle or bicycle may col-
lide with a door when open-
ing it or cancel opening of
the door, to reduce the pos-
sibility of a collision.
WARNING
■Cautions regarding the use of
the system
●The driver is solely responsible
for safe driving. Always drive
safely, taking care to observe
your surroundings.
●The safe exit assist is a supple-
mentary system that, when the
vehicle is stopped, informs
occupants of the existence of
approaching vehicles and bicy-
cles. As this system alone can-
not be used to judge safety,
over-reliance on this system
may lead to an accident result-
ing in death or serious injury.
In certain situations, this system
may not function to its fullest
extent. Therefore it is necessary
for the occupants to visually
check for safety directly and using
the mirrors.

When the system determines that
the possibility of a collision with a
door is high, the target door is dis-

when the outside rear view mirror
indicator is illuminated, a buzzer
will sound as a warning.
Outside rear view mirror indi-
cators
When a vehicle or bicycle which
may collide with a door (other than
the back door) when opened is
detected, the outsid e rear view mir-
ror indicator on t he detected side
will illuminate. When a door on the
detected side is opened, the out-
side rear view mirror indicator will
flash.
