Driving
●On an extremely bumpy road, on an
incline, on gravel, or on grass.
●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
●A sensor is coated with a sheet of spray or heavy rain.
●If objects draw too close to the sensor.
●Pedestrians that are hard to reflect
ultrasonic waves (ex. skirts with gath- ers or frills).
●When objects that are not perpendicu-lar to the ground, not perpendicular to the vehicle traveling direction,
uneven, or waving are in the detection range.
●Strong wind is blowing
●When driving in inclement weather
such as fog, snow or a sandstorm
●When an object that cannot be
detected is between the vehicle and a detected object
●If an object such as a vehicle, motor-cycle, bicycle or pedestrian cuts in front of the vehicle or runs out from
the side of the vehicle
●If the orientation of a sensor has been
changed due to a collision or other impact
●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
●If the front of the vehicle is raised or lowered due to the carried load
●If the vehicle cannot be driven in a
stable manner, such as when the vehicle has been in an accident or is malfunctioning
●When a tire chains, compact spare tire or an emergency tire puncture repair
kit is used
■Situations in which the system may operate even if there is no possibil-ity of a collision
In some situations, such as the follow- ing, the system may operate even though there is no possibility of a colli-
sion.

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.

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)
