*: If equipped
RCTA (Rear Cross Traf-
fic 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,
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.

Operate the meter control switches
to enable/disable the RCTA func-
tion on the multi-information dis-
play.
Outside rear view mirror indi-
cators
If a vehicle is detected as
approaching from the left or right
behind the vehicle, both outside
rear view mirror indicators will blink
and a buzzer will sound.
Audio system screen
If a vehicle appr oaching from the
right or left at the rear of the vehicle
is detected, the RCTA icon
(  P.259) for the det ected side will
be displayed on t he audio system
screen. This illustration
* shows an
example of a vehicle approaching
from both sides of the vehicle.
*: Depending on the vehicle grade and equipped options, the actual
screen may be different from this illustration.
Driving assist information
indicator
Illuminates when the RCTA is
turned off. At this time, “Rear Cross
Traffic Alert OFF”
will be displayed
on the multi-information display.
The RCTA can be enabled/dis-
abled on of the multi-infor-
mation display. ( P.463)
When the RCTA function is off,
the driving assist information
indicator ( P.82) will illuminate.
At this time, “Rear Cross Traffic
Alert OFF” will be displayed on
the multi-information display.
Each time the power switch is
turned to ON, the RCTA is
enabled.
■Outside rear vie w mirror indica-
tor visibility
In strong sunlight, the outside rear
view mirror indicator may be difficult
to see.
■Hearing the RCTA buzzer

■The RCTA function is opera-
tional when
The RCTA function operates when
all of the followin g conditions are
met:
●The power switch is in ON.
●The RCTA function is on.
●The shift position is in R.
●The vehicle speed is less than
approximately 9 mph (15 km/h).

intuitive parking assi st (if equipped)
can be adjusted all together on
of the multi-information display.
(  P.463)
■Muting a buzzer temporarily (if
equipped)
When an object is detected, the
temporary mute switch is displayed
on the audio system screen.
S elect the switch to mute the buzzer
of the intuitive parking assist (if
equipped) and RCTA all together.
Mute will be canceled automatically
in the followin g situations:
●When the shift lever is changed.
●When the vehicle speed exceeds
a certain speed.
●When there is a malfunction in a sensor or the system is temporar-
ily unavailable.
●When the operati
ng function is
disabled manually.
●When the power switch is turned
off.
■Conditions under which the
system will not detect a vehicle
The RCTA function is not designed
to detect the follo wing types of vehi-
cles and/or objects:
●Vehicles approaching from directly
behind
●Vehicles backing up in a parking
space next to your vehicle
●Vehicles that the sensors cannot
detect due to obstructions
●Guardrails, walls, signs, parked
vehicles and similar stationary
objects
*
●Small motorcycles, bicycles,
pedestrians, etc.*
●Vehicles moving away from your
vehicle
●Vehicles approaching from the
parking spaces nex t to your vehi-
cle
*
●The distance between the sensor
and approaching vehicle gets too
close
*: Depending on the conditions, detection of a v ehicle and/or
object may occur.

unnecessary detec ting a vehicle
and/or object may increase in the
following situations:
●When the parking space faces a
street and vehicles are being
driven on the street

vehicle and metal objects, such as
a guardrail, wall, sign, or parked
vehicle, which may reflect electri-
cal waves toward the rear of the
vehicle, is short

Multi-information display
Turning the safe exit assist on/off.
When the system determines that
the possibility of a collision with a
door is high, the target door is dis-
played on the multi-information dis-
play. Also, if the door is opened
when the outside r ear 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 outside rear view mir-
ror indicator on the detected side
will illuminate. When a door on the
detected side is opened, the out-
side rear view mirror indicator will
flash.
Driving assist information
indicator
Illuminates when the safe exit
assist is turned off. At this time,
“Safe Exit Assist OFF” will be dis-
played on the multi-information dis-
play.
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.

■Outside rear view mirror indica-
tor visibility
In strong sunlight, the outside rear
view mirror indicato r may be difficult
to see.
■Buzzer
If the volume setting of the audio
system is high or the surrounding
area is loud, it may be difficult to
hear the buzzer.
■Customization
Some functions can be customized.
(  P.463)
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 approximatel y 10 minutes. If
the warning message does not
disappear, have the vehicle
inspected by you r Toyota dealer.
●Do not attach accessories,
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 mal-
function and vehicles may not be
detected correctly. In the following
situations, have your vehicle
inspected by you r 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.
