RCTA (Rear Cross Traf-
fic Alert) 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 observe 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 reliance on this func-
tion may lead to an accident
resulting death or serious injury.

vehicle, which may reflect electri-
cal waves toward the rear of the
vehicle, is short

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.

WARNING
■To ensure the system can
operate properly
Safe exit assist sensors are
installed behind the left and right
sides of the rear bumper respec-
tively. Observe the following to
ensure the safe exit assist can
operate correctly.
●Keep the sensors and the sur-
rounding areas on the rear
bumper clean at all times.
If a sensor or its surrounding area
on the rear bumper is dirty or cov-
ered with snow, the Safe Exit
Assist may not operate and a
warning message will be dis-
played. In this situation, clear off
the dirt or snow and drive the
vehicle with the operation condi-
tions of the SEA function satisfied
for approximately 10 minutes. If
the warning message does not
disappear, have the vehicle
inspected by your Toyota dealer.
●Do not attach a ccessories,
stickers (including transparent
stickers), aluminum tape, etc. to
a sensor or its surrounding area
on the rear bumper.
●Do not subject a sensor or its
surrounding area on the rear
bumper to a strong impact.
If a sensor is moved even
slightly off position, the system
may malfunction and vehicles
may not be detected correctly.
In the following si tuations, have
your vehicle inspected by your
Toyota dealer.
• A sensor or its surrounding area is subject to a strong impact.
• If the surrounding area of a sen- sor is scratched or dented, or
part of them h as become dis-
connected.
●Do not disassemble the sensor.
●Do not modify the sensor or sur-
rounding area on the rear
bumper.
●If a sensor or the rear bumper
needs to be removed/installed
or replaced, contact your Toyota
dealer.
●Do not paint the rear bumper
any color other t han an official
Toyota color.
