■Buzzer operation and dis-
tance to an object
A buzzer sounds when the sensors
are operating.
 The buzzer beeps faster as the
vehicle approaches an object.
When the vehicle comes within
approximately 30 cm (1.0 ft.) of
the object, the buzzer sounds
continuously.
 When 2 or more sensors simulta-
neously detect a static object,
the buzzer sounds for the near-
est object.
 Even when the sensors are oper-
ating, the buzzer will be muted in
some situations. (automatic
buzzer mute function)
■Adjusting the buzzer volume
The buzzer volume can be adjusted
on the multi-information display.
Use the meter control switches to
change settings. ( P.176)
1 Press or of the meter
control switch to select .
2 Press or of the meter
control switch to select and
then press and hold .
3 Select the volume and then
press .
Each time the switch is pressed, the volume level will change between 1, 2, and 3.
■Muting a buzzer temporarily
When an object is detected, the
temporary 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
sensor or the system is tempo-
rarily unavailable.
 When the operating function is
disabled manually.
 When the power switch is turned
off.
The object warning function informs
the driver of the existence of
objects along the side of the vehi-
cle, using a display and buzzer, if
the objects are within the estimated
path of the vehicle.

Object
Calculated vehicle route
When the vehicle is moving, the side sensors or side cameras ca n detect
objects. While the vehicle is moving, if a detected object can no longer be
detected by the side sensors or side cameras, the location of t he object rel-
ative to the vehicle is estimated. If the object is determined to be in the esti-
mated path of the vehicle, the object warning function will ope rate.
Object detected by side sensors or side cameras
1 The vehicle is stopped and objects along the sides of the vehicle are not
detected.
2 Objects are detected as the vehicle is moving.
3 Even though the objects are outside of the detection area of the side
sensors or side cameras, a warning is displayed and a buzzer so unds.
■Object warning function operating conditions
●The Advanced Park is operating.
●The vehicle moves about 7 m (23.0 ft.)
after the EV system is started.
●The R shift position is selected.
●After the D shift position has been selected, the vehicle has moved 7 m
(23.0 ft.) or less.
●Camera switch has been pressed and
the multimedia display is displayed.
●The front or rear sensor detects a sta-
tionary object.
■Detection of objects along the sides of the vehicle
●Objects along the sides of the vehicle are not instantaneously detected. The location of objects in relation to the
vehicle is estimated after they are first detected by the front or rear side sen-sors, or side cameras. Therefore, after

342
Owners Manual_Europe_M42D76_en
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

approaching from both sides of the
vehicle.

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.

ate properly

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.

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
●Immediately after the RCTA function is turned on

■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
●Moving objects (flags, exhaust fumes, large rain droplets or snowflakes, rain
water on the road surface, etc.)
●When the distance between your vehi-
cle and a guardrail, wall, etc., that enters the detection area is short
●Gratings and gutters

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.
