●When vehicle horns, vehicle detec-
tors, motorcycle engines, air brakes of large vehicles, the clearance sonar of other vehicles or other devices which
produce ultrasonic waves are near the vehicle

●If the orientation of a sensor has been changed due to a collision or other impact
●The vehicle is approaching a tall or curved curb
●Driving close to columns (H-shaped steel beams, etc.) in multi-story park-
ing garages, construction sites, etc.
●If the vehicle cannot be driven in a
stable manner, such as when the vehicle has been in an accident or is malfunctioning
●On an extremely bumpy road, on an incline, on gravel, or on grass
●When a tire chains, compact spare tire or an emergency tire puncture repair
kit is used

■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.107, 113)

Each time the switch is pressed, the volume level will change between 1, 2,
and 3.
■Muting a buzzer
A mute button will be displayed on
the multi-information display when
an object is detected. To mute the
buzzer, press .
The buzzers for the Toyota parking
assist-sensor and RCTA function (if
equipped) will be muted simultane-
ously.
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
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 hybrid 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 panoramic view monitor screen 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
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
■Object warning function
In situations such as the following, the function may not operate correctly,
possibly leading to an accident. Pro- ceed carefully.

*: If equipped
WARNING
●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.
RCTA (Rear Crossing
Traffic Alert)*
The RCTA function uses the
BSM radar sensors installed
on the inner side of the posi-
tion above 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
There is a limit to the degree of recog- nition accuracy and control perfor-mance that this system can provide,
do not overly rely on this system. The driver is always responsible for paying attention to the vehicle’s surroundings
and driving safely. ( P.270)
