RCD (Rear Camera
Detection)*
When the vehicle is backing
up, the rear camera detec-
tion function can detect
pedestrians in the detec-
tion area behind the vehicle.
If a pedestrian is detected, a
buzzer will sound and an
icon will be displayed on
the multimedia display to
inform the driver of the
pedestrian.
WARNING
■Cautions regarding the use of
the system
The recognition and control capa-
bilities for this system are limited.
The driver should always drive
safely by always being responsi-
ble without over relying on the
system and have a understanding
of the surrounding situations.
■To ensure the system can
operate properly
Observe the following, otherwise
there is the danger that could lead
to an accident.
●Always clean the camera with-
out damaging it.
●Do not install market electronic
parts (such as Illuminated
license plate, fog lamps, etc.) in
the camera vicinity.
●Do not subject the camera vicin-
ity to strong impacts. If the vicin-
ity is subjected to a strong
impact, have the vehicle
inspected at a Toyota dealer.

●The power switch is in ON.
●RCD function is on.
●The shift position is in R.
●Advanced Park is not operating.
■Setting the buzzer volume
The buzzer volume can be adjusted
on the multi-information display.
Use the meter control switches to
change settings. ( P.106)
■Muting a buzzer temporarily
When an object i s detected, the
temporary mute switch is displayed
on the multimedia display system.
Select to mute a buzzer of the
intuitive parking assist, RCTA and
RCD all together.
Mute will be cancele d automatically
in the following 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.
■If “Rear Camera Detection
Unavailable Remo ve the Dirt of
Rear Camera” is displayed on
the multi-info rmation display
The rear camera lens may be dirty
or covered with snow or ice. In such
cases, if it is removed from the rear
camera lens, the system should
return to normal. (It may be neces-
sary to drive the v ehicle for some
time before the system returns to
normal.)
■If “Rear Camera Detection
Unavailable” is displayed on

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

■If “PKSB Unavailable” is dis-
played on the multi-information
display and the PKSB OFF indi-
cator is on
If the vehicle is stopped due to oper-
ation of the Parki ng Support Brake,
the Parking Suppor t Brake will be
disabled and the PKSB OFF indica-
tor will illuminate.
●A sensor may be covered with
water drops, ice, snow, dirt, etc.
Remove the water drops, ice,
snow, dirt, etc., from the sensor to
return the system to normal.
Also, due to ice forming on a sen-
sor at low temperatures, a warn-
ing message may be displayed or
the sensor may n ot be able to
detect an object. Once the ice
melts, the system will return to
normal.
●If this message is displayed only
when the R shift position is
selected, the rear camera lens
may be dirty. Clean the camera
lens. If this message is displayed
when the shift position is any posi-
tion other than R, a sensor on the
front or rear bumper may be dirty.
Clean the sensors and their sur-
rounding area on the bumpers.
●If this message continues to be
displayed even after cleaning the
sensor, or is displayed even
though the sensor is clean, have
the vehicle inspected by your Toy-
ota dealer.
■Intuitive parking assist buzzer
Regardless of whether the Intuitive
parking assist buzzer is enabled or
not, if the PKSB ( Parking Support
Brake) system is enabled, the front
or rear sensors detect a static object
and brake control is performed, the
Intuitive parking assist buzzer will
sound to notify the driver of the
approximate distanc e to the object.
*: If equipped
This function will operate in situ-
ations such as the following if an
object is detected in the travel-
ing direction of the vehicle.

function (static
objects front and rear
of the vehicle/static
objects around the
vehicle
*)
If the sensors detect a static
object, such as a wall, in the
traveling direction of the
vehicle and the system
determines that a collision
may occur due to the vehi-
cle suddenly moving for-
ward due to an accidental
accelerator pedal operation,
the vehicle moving the
unintended direction due to
the wrong shift position
being selected, or while
parking or traveling at low
speeds, the system will
operate to lessen the impact
with the detected static
object and reduce the
resulting damage.

• The static object is no longer approximately 6 to 13 ft. (2 to 4 m)
away from the vehicle or in the
traveling directi on of the vehicle.
●Brake control
• The Parking Support Brake is dis- abled.
• Approximately 2 seconds have elapsed since the vehicle was

• The brake pedal is depressed after the vehicle is stopped by
brake control.
• The static object is no longer approximately 6 to 13 ft. (2 to 4 m)
away from the vehicle or in the
traveling directi on of the vehicle.
■Detection range
The detection range of the Parking
Support Brake function (static
objects front and r ear of the vehi-
cle/static objects around the vehicle)
differs from the detection range of the intuitive parking assist. (
P.266)
Therefore, even if the intuitive park-
ing assist detects an object and pro-
vides a warning, the PKSB (Parking
Support Brake) may not start oper-
ating.

■Detection range
The detection range of the moving

if the RCTA function detects a vehi-
cle and provides an alert, the mov-
ing vehicles rear of the vehicle may
not start operating.
