lowing vehicles traveling in adjacent lanes and advises the driver of
the presence of such vehicles via the indicators on the outside rear
view mirrors.
Vehicles that are traveling in areas that are not visible using the
outside rear view mirrors (the blind spots)
Vehicles that are approaching r apidly from behind in areas that
are not visible using the outside rear view mirrors (the blind spots)
■Detection range while driving
The areas that vehicles can be detected in are outlined below.
WARNING
●Do not disassemble the sensor.
●Do not modify the sensor or sur-
rounding area on the rear
bumper.
●If a sensor or th e rear bumper
needs to be removed/installed
or replaced, contact your Toyota
dealer.
●Do not paint the rear bumper

WARNING
■Cautions regarding the use of
the system
There is a limit t o the degree of
recognition accuracy and control
performance that this system can
provide, do not overly rely on this
system. The driver is always
responsible for paying attention to
the vehicle’ surroundings and
driving safely.
■To ensure the system can
operate properly
Observe the following precau-
tions.
Failing to do so may result in the
vehicle being unable to be driven
safely and possibly cause an acci-
dent.
●Do not damage the sensors,
and always keep them clean.
●Do not attach a sticker or install
an electronic component, such
as a backlit licen se plate (espe-
cially fluorescent type), fog
lights, fender po le or wireless
antenna near a radar sensor.
●Do not subject the surrounding
area of the sensor to a strong
impact. If subjected to an
impact, have the vehicle
inspected by your Toyota
dealer. If the front or rear
bumper needs to be
removed/installed or replaced,
contact your Toyota dealer.
●Do not modify, disassemble or
paint the sensors.
●Do not attach a license plate
cover.
●Keep your tires properly
inflated.

Driving
■The system can be operated
when
●The engine switch is in ON.
●Intuitive parking assist function is
on.
●The vehicle speed is less than
about 6 mph (10 km/h).
●A shift lever other than P.
■If “Parking Assist Unavailable”
is displayed on the multi-infor-
mation display
●Water may be continuously flow-
ing over the sensor surface, such
as in a heavy rain. When the sys-
tem determines that it is normal, the system will retu
rn to normal.
●Initialization may not have been
performed after a battery terminal
was disconnected and recon-
nected. Initialize the system.
( P.277) If this message contin-
ues to be displayed even after ini-
tialization, have the vehicle
inspected by your Toyota dealer.
■If “Parking Assist Unavailable
Clean Parking Assist Sensor” is
displayed on the multi-informa-
tion display
A sensor may be covered with ice,
snow, dirt, etc. Remove the ice,
snow, dirt, etc., from the sensor to
return the system to normal.
Also, due to ice forming on a sensor
at low temperatures, a warning
message may be displayed or the
sensor may not be able to detect an
object. Once the ice melts, the sys-
tem will return to normal.
■If a battery terminal has been
disconnected and reconnected
The system needs to be initialized.
To initialize the system, drive the
vehicle straight ahead for 5 seconds
or more at a speed of approximately
22 mph (35 km/h) or more.
■Sensor detection information
●The following situations may occur
during use.
• The sensor's detec tion areas are
limited to the areas around the
vehicle front and rear bumpers.
• Depending on the shape of the
object and other factors, the
detection distance may shorten, or
detection may be impossible.
• If an object is extremely close to a sensor, it may not be detected.
• There will be a short delay between object detection and dis-
play. Even at low speeds, there is
a possibility that the object will
come within the sensor’s detec-
tion areas before the display is
shown and the warning beep
sounds.
WARNING
■When to disable the function
In the following situations, disable
the function as it may operate
even though there is no possibility
of a collision.
●Failing to observe the warnings
above.
●A non-genuine Toyota suspen-
sion (lowered suspension, etc.)
is installed.
■Notes when washing the vehi-
cle
Do not apply intensive bursts of
water or steam to the sensor
area.
Doing so may result in the sensor
malfunctioning.
●When using a high pressure
washer to wash the vehicle, do
not spray the sensors directly,
as doing so may cause a sensor
to malfunction.
●When using steam to clean the
vehicle, do not direct steam too
close to the sensors as doing so
may cause a sens or to malfunc-
tion.

tone, followed by fast beeps.
 Automatic buzzer mute func-
tion: After a buzzer begins
sounding, if the distance
between the vehicle and the
detected object does not
become shorter, the buzzer
will be muted automatically.
(However, if the distance
between the vehicle and
object is 1.0 ft. (30 cm) or
less, this function will not
operate.)
The buzzer sounds volume can
be adjusted. (P.280)
*: If equipped
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 sup-
plementary 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
function correctly under certain
conditions, the driver’s own visual
confirmation of safety is neces-
sary.
Over reliance on this function may
lead to an accident resulting
death or serious injury.

PKSB (Parking Sup-
port Brake)*
The Parking Support Brake
system consists of the fol-
lowing functions that oper-
ate when driving at a low
speed or backing up, such
as when parking. When the
system determines that the
possibility of a collision
with a detected object is
high, a warning operates to
urge the driver to take eva-
sive action. If the system
determines that the possi-
bility of a collision with a
detected object is extremely
high, the brakes are auto-
matically applied to help
avoid the collision or help
reduce the impact of the col-
lision.

WARNING
■Cautions regarding the use of
the system
Do not overly rely on the system,
as doing so may lead to an acci-
dent.
Always drive while checking the
safety of the surroundings of the
vehicle.
Depending on the vehicle and
road conditions, weather, etc., the
system may not operate.
The detection capa bilities of sen-
sors and radars are limited.
Always drive while checking the
safety of the surroundings of the
vehicle.
●The driver is solely responsible
for safe driving. Always drive
carefully, taking care to observe
your surroundings. The Parking
Support Brake system is
designed to provide support to
lessen the severity of collisions.
However, it may not operate in
some situations.
●The Parking Support Brake sys-
tem is not designed to stop the
vehicle completely. Additionally,
even if the system has stopped
the vehicle, it is necessary to
depress the brake pedal imme-
diately as brake control will be
canceled after approximately 2
seconds.
●It is extremely dangerous to
check the system operations by
intentionally driving the vehicle
into the direction of a wall, etc.
Never attempt such actions.
■When to disable the Parking
Support Brake
In the following situations, disable
the Parking Suppor t Brake as the
system may opera te even though
there is no possibility of a colli-
sion.
●When inspecting the vehicle
using a chassis roller, chassis
dynamo or free roller
●When loading the vehicle onto a
boat, truck or other transport
vessel
●If the suspension has been
modified or tires of a size other
than specified are installed
●If the front of the vehicle is
raised or lowered due to the
carried load
●When equipment that may
obstruct a sensor is installed,
such as a towing eyelet, bumper
protector (an additional trim
strip, etc.), bicycle carrier, or
snow plow
●When using automatic car
washing devices
●If the vehicle cannot be driven in
a stable manner, such as when
the vehicle has been in an acci-
dent or is malfunctioning
●When the vehicle is driven in a
sporty manner or off-road
●When the tires are not properly
inflated
●When the tires are very worn
●When a tire chains, compact
spare tire or an emergency tire
puncture repair kit is used
●When your vehicle is towing a
trailer or during emergency tow-
ing
