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).
●The approaching vehicle speed is
between approximately 5 mph (8
km/h) and 34 mph (56 km/h).
■Adjusting the buzzer volume
The buzzer volume can be adjusted
on the multi-information display.
Use the meter control switches to

ng function is
disabled manually.
●When the power switch is turned
off.
■Conditions under which the

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.
■Situations in which the system
may not operate properly

WARNING
■Cautions regarding the use of
the system
The recognition and control capa-
bilities for this system are limited.
The driver shoul d 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 follo wing, 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.
●Do not disassemble, remodel or
paint the camera.
●Do not attach accessories or
stickers to the camera.
●Do not install market protection
parts (bumper tr im, etc.) to the
rear bumper.
●Maintain suitable tire air pres-
sure.
●Make sure the trunk is com-
pletely closed.
■RCD function i s turned off
In the following situations the sys-
tem turns off. The RCD function
may not operate properly and
thus there is the danger that an
accident may occur.

the multi-information 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 vehicle for some
time before the system returns to
normal.)

and then the right on level ground.
●If this message is displayed only
when the R shift position is
selected, the rear camera lens
may be dirty. Clean the rear cam-
era lens.
■Situations in which the system
may not operate properly
●Some pedestrians, such as the
following, may not be detected by
the rear camera detection func-
tion, preventing the function from
operating properly:
• Pedestrians who are bending for- ward or squatting
• Pedestrians who are lying down
• Pedestrians who are running
• Pedestrians who suddenly enter the detection area
• People riding a bicycle, skate- board, or other light vehicle • Pedestrians wearing oversized
clothing such as a rain coat, long
skirt, etc., making their silhouette
obscure
• Pedestrians whose body is par- tially hidden by an object, such as
a cart or umbrella
• Pedestrians which are obscured by darkness, such as at night
●In some situations, such as the
following, pedestrians may not be
detected by the rear camera
detection function, preventing the
function from operating properly:
• When backing up in inclement weather (rain, snow, fog, etc.)
• When the rear camera is
obscured (dirt, snow, ice, etc., are
attached) or scratched
• When a very bright light, such as
the sun, or the headlights of
another vehicle, shines directly
into the rear camera
• When backing up in a place where the surrounding brightness
changes suddenly, such as at the
entrance or exi t of a garage or
underground parking lot
• When backing up in a dim envi-
ronment such as during dusk or in
an underground parking lot
• When the camera position and
direction are deviated
• When a towing hook is attached
• When water droplets are flowing on the camera lens
• When the vehicle height is extremely changed (nose up,
nose down).
• When tire chains or an emergency tire puncture repair kit is used
■Situations in which the system
may operate unexpectedly
●Even though there are no pedes-
trians in the detection area, some
objects, such as the following,
may be detected, possibly caus-
ing the rear cam era detection
function to operate.
• Three dimensional objects, such as a pole, traffic cone, fence, or
parked vehicle
• Moving objects, such as a car or

the Parking Support Brake as the
system may operate even though
there is no poss ibility of a colli-
sion.
●When inspecting the vehicle
using a chassis roller, chassis
dynamo or free roller

■Re-enabling the Parking Sup-
port Brake
To re-enable the Parking Support
Brake when it has been disabled
due to operation of the Parking Sup-
port Brake, either enable the system
again ( P.274), or turn the power
switch off and then back to ON.
Additionally, if any of the following
conditions are me t, the system will
be re-enabled automatically and the
PKSB OFF indicato r will turn off:
●The P shift position is selected
●The object is no longer detected in
the traveling direction of the vehi-
cle
●The traveling direction of the vehi-
cle changes*
*
: Except when the Parking Support Brake function (rear pedestrians)
operated.
■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.
■If a 12-volt battery terminal has
been disconnected and recon-
nected
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.
