■Operation of the RCTA func-
tion
The RCTA function uses radar sen-
sors to detect vehicles approaching
from the right or left at the rear of
the vehicle and alerts the driver of
the presence of such vehicles by
flashing the outside rear view mirror
indicators and sounding a buzzer.
Approaching vehicles
Detection areas
■RCTA icon display (vehicles
with navigation/multimedia
system)
When a vehicle approaching from
the right or left at the rear of the
vehicle is detected, the following
will be displayed on the naviga-
tion/multimedia system display.
This illustration shows an example of a
vehicle approaching from both sides of
the vehicle.
■RCTA function detection areas
The areas that vehicles can be
detected in are outlined below.
The buzzer can alert for faster vehicles
approaching from farther away.
Example:
■The RCTA function is operational when
The RCTA function operates when all of
the following conditions are met:
●The RCTA function is on.
●The shift lever is in R.

●The vehicle speed is less than
approximately 15 km/h (9 mph).
●The approaching vehicle speed is
between approximately 8 km/h (5 mph) and 56 km/h (34 mph).
■Adjusting the buzzer volume
The buzzer volume can be adjusted on
the multi-information display.
Use the meter control switches to change settings. ( P.107, 113)
1 Press / (4.2-inch display) or
/ (7-inch display) of the
meter control switch to select .
2 Press / (4.2-inch display) or
/ (7-inch display) of the
meter control switch to select
“RCTA” and then press and hold
.
3 Press to select the volume.
Each time the switch is pressed, the vol-
ume level will change between 1, 2, and 3.
When the buzzer volume adjustment is
completed, press to return to the
previous screen.
■Muting a buzzer temporarily
A mute button will be displayed on the
multi-information display when a vehi-
cles or an object is detected. To mute
the buzzer, press .
The buzzers for the RCTA function and
Toyota parking assist-sensor will be
muted simultaneously.
Mute will be canceled 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 sen-
sor or the system is temporarily unavailable.
●When the operating function is dis-abled 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 following types of vehicles 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 vehi-
cles and similar stationary objects*
●Small motorcycles, bicycles, pedestri-
ans, etc.*
●Vehicles moving away from your vehi- cle
●Vehicles approaching from the park-
ing spaces next to your vehicle*
●The distance between the sensor and approaching vehicle gets too close*: Depending on conditions, detection of
a vehicle and/or object may occur.
■Situations in which the system may
not operate properly
The RCTA function may not detect vehi-
cles correctly in the following situations:
●When the sensor is misaligned due to
a strong impact to the sensor or its surrounding area

Driving
●When mud, snow, ice, a sticker, etc.,
is covering the sensor or surrounding area on the position above the rear bumper
●When driving on a road surface that is wet with standing water during bad
weather, such as heavy rain, snow, or fog
●When multiple vehicles are approach-ing with only a small gap between each vehicle
●When a vehicle is approaching at high speed
●When equipment that may obstruct a sensor is installed, such as a towing
eyelet, bumper protector (an addi- tional trim strip, etc.), bicycle carrier, or snow plow
●When backing up on a slope with a sharp change in grade
●When backing out of a sharp angle parking spot
●When towing a trailer
●When there is a significant difference
in height between your vehicle and the vehicle that enters the detection area
●When a sensor or the area around a sensor is extremely hot or cold
●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 turning while backing up
●When a vehicle turns into the detec- tion area
■Situations in which the system may operate even if there is no possibil-
ity of a collision
Instances of the RCTA function unnec- essary detecting 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

●When the distance between your vehi-
cle and metal objects, such as a guardrail, wall, sigh, or parked vehicle, which may reflect electrical waves
toward the rear of the vehicle, is short
●When equipment that may obstruct a
sensor is installed, such as a towing eyelet, bumper protector (an addi-tional trim strip, etc.), bicycle carrier,
or snow plow
●When a vehicle passes by the side of
your vehicle
●When a detected vehicle turns while
approaching the vehicle
●When there are spinning objects near
your vehicle such as the fan of an air conditioning unit
●When water is splashed or sprayed toward the rear bumper, such as from a sprinkler
●Moving objects (flags, exhaust fumes, large rain droplets or snowflakes, rain
water on the road surface, etc.)

cle and a guardrail, wall, etc., that enters the detection area is short

PKSB (Parking Support
Brake)*
The Parking Support Brake
system consists of the follow-
ing functions that operate
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 oper-
ates to urge the driver to take
evasive action. If the system
determines that the possibility
of a collision with a detected
object is extremely high, the
brakes are automatically
applied to help avoid the colli-
sion or help reduce the impact
of the collision.

Brake) system
WARNING
■Cautions regarding the use of the system
Do not overly rely on the system, as doing so may lead to an accident.
Always drive while checking the
safety of the surroundings of the vehi- cle.
Depending on the vehicle and road
conditions, weather, etc., the system may not operate.
The detection capabilities of sensors
and radars are limited. Always drive while checking the safety of the sur-roundings of the vehicle.
●The driver is solely responsible for safe driving. Always drive carefully,
taking care to observe your sur- roundings. The Parking Support Brake system is designed to pro-
vide support to lessen the severity of collisions. However, it may not operate in some situations.
●The Parking Support Brake system 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 immediately as brake control will be canceled after approximately 2 seconds.
●It is extremely dangerous to check the system operations by intention-
ally driving the vehicle into the direction of a wall, etc. Never attempt such actions.
■When to disable the Parking Sup-port Brake
In the following situations, disable the Parking Support Brake as the system may operate even though there is no
possibility of a collision.
●When inspecting the vehicle using
a chassis roller, chassis dynamo or free roller

Support Brake functions (static
objects and rear-crossing vehicles)
are enabled/disabled simultane-
ously.
Use the meter control switches to
enable/disable the parking support
brake. ( P.107, 113)

WARNING
●When loading the vehicle onto a boat, truck or other transport vessel
●If the suspension has been modi-fied 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 tow- ing 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 accident 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 towing
NOTICE
■If “PKSB Unavailable” is dis-played on the multi-information
display and the PKSB OFF indi- cator is on
If this message is displayed immedi-
ately after the power switch is changed to ON, operate the vehicle carefully, paying attention to your sur-
roundings. It may be necessary to drive the vehicle for a certain amount of time before the system returns to
normal. (If the system is not return to normal after driving for a while, clean the sensors and their surrounding
area on the bumpers.)
