5-4. Using the driving support systems
the power switch is changed to ON,
even if an object is along the side of the vehicle, it may not be detected until the vehicle has been driven a
small amount and the side sensors or side cameras completely scan the areas along the sides of the vehicle.
●If a vehicle, person, animal, etc., is detected by a side sensors or side
cameras, but then leaves the detec- tion area of the side sensors or side cameras, the system will assume the
object has not moved.
WARNING
■Side sensors and side cameras
In situations such as the following, the
function may not operate correctly, possibly leading to an accident. Pro-ceed carefully.
●When starting off shortly after the power switch is turned to ON and a
small vehicle or other object which cannot be detected by a front side sensor is next to the vehicle.
In the situation shown in the following
illustration, even if the vehicle starts
off, the vehicle on the left will not be
detected and the object warning func-
tion will not operate.
●When an object or person is in a position which cannot be detected
by the side sensors or side cam- eras.
●When, after the side sensors have completed scanning the areas along the sides of the vehicle, a
vehicle, person, or other object approaches the side of the vehicle and cannot be detected.
●When the outside rear view mirror is closed, the side sensors or side
cameras cannot detect objects.
●If the 12-volt battery was dis-
charged or has been removed and installed, fold and extend the out-side rear view mirrors.

If a vehicle approaching from the right
or left at the rear of the vehicle is
detected, the RCTA icon ( P.344) for
the detected side will be displayed on
the multimedia display. This illustration

tor
When the RCTA is off, “Rear Cross
Traffic Alert OFF” will be displayed on

RCTA (Rear Crossing
Traffic 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, tak-ing care to observe your surround-
ings.
The RCTA function is only a supple-
mentary 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 func-
tion correctly under certain conditions, the driver’s own visual confirmation of safety is necessary.
Over reliance on this function may lead to an accident resulting death or
serious injury.

visibility
In strong sunlight, the outside rear view mirror indicator may be difficult to see.
■Hearing the RCTA buzzer
The RCTA buzzer may be difficult to hear over loud noises, such as high audio volume.
■Radar sensors
 P. 3 2 5
■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.

The buzzer can alert for faster vehi-
cles approaching from farther away.
Example:
■The RCTA function is operational when
The RCTA function operates when all of the following 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 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.
The volume of the RCTA buzzer can be
adjust on of the multi-information
display. ( P.340)
■Muting a buzzer temporarily
When an object is detected, the tempo-
rary mute switch is displayed on the
multimedia display system.
Select to mute a buzzer of the
Toyota parking assist-sensor, RCTA and
RCD all together.
Mute will be canceled automatically in the following situations:
●When the shift position 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

●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

a strong impact to the sensor or its surrounding area
●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

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, sign, 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

*: If equipped
RCD (Rear Camera
Detection)*
When the vehicle is backing
up, the rear camera detection
function can detect pedestri-
ans in the detection area
behind the vehicle. If a pedes-
trian is detected, a buzzer will
sound and an icon will be dis-
played on the multimedia dis-
play to inform the driver of the
pedestrian.
WARNING
■Cautions regarding the use of the system
The recognition and control capabili- ties for this system are limited.
The driver should always drive safely
by always being responsible without over relying on the system and have a understanding of the surrounding situ-
ations.
■To ensure the system can oper-
ate properly
Observe the following, otherwise there is the danger that could lead to
an accident.
●Always clean the camera without
damaging it.
●Do not install market electronic
parts (such as Illuminated license plate, fog lamps, etc.) in the camera vicinity.
