■Buzzer operation and dis-
tance to an object
A buzzer sounds when the sen-
sors are operating.
 The buzzer beeps faster as
the vehicle approaches an
object.
When the vehicle comes
within approximately 1.0 ft.
(30 cm) of the object, the
buzzer sounds continuously.
 When 2 or more sensors
simultaneously detect a static
object, the buzzer sounds for
the nearest object.
 Even when the sensors are
operating, the buzzer will be
muted in some situations.

Mute will be canceled automati-
cally 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
temporarily unavailable.
 When the operating function
is disabled manually.
 When the power switch is
turned off. The object warning function
informs the driver of the exis-
tence of objects along the side
of the vehicle, 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 obje ct can
no longer be detected by the side sensors or side cameras, the loca-
tion of the object relative to the vehicle is estimated. If the object is
determined to be in the estimated path of the vehicle, the obje ct
warning function will operate.

2 Objects are detected as the vehicle is moving.
3 Even though the objects are out side of the detection area of the
side sensors or side cameras, a warning is displayed and a
buzzer sounds.
■Object warning function operat-
ing conditions
●The Advanced Park is operating.
●The vehicle moves about 23.0 ft.
(7 m) after the EV system is
started.
●The R shift position is selected.
●After the D shift position has been
selected, the vehicle has moved
23.0 ft. (7 m) or less.
●Camera switch has been pressed
and the panoramic view monitor
screen is displayed.
●The front or rear s ensor detects a
stationary 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 esti-
mated after they are first detected
by the front or rear side sensors,
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 th e 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
detection area of the side sensors
or side cameras, the system will
assume the object has not moved.
WARNING
■Side sensors and side cam-
eras
In situations such as the following,
the function may not operate cor-
rectly, possibly leading to an acci-
dent. Proceed 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 s hown in the fol-
lowing illustration, even if the
vehicle starts off, the vehicle on
the left will not be detected and
the object warni ng function will
not operate.
●When an object or person is in a
position which cannot be
detected by the side sensors or
side cameras.
●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.

*: If equipped
WARNING
●When the outside rear view mir-
ror 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 outside rear view mirrors.
RCTA (Rear Cross Traf-
fic Alert)*
The RCTA function uses the
BSM rear side radar sen-
sors 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,
taking care to observe your sur-
roundings.
The RCTA function is only a sup-
plementary 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
function correctly under certain
conditions, the driver’s own visual
confirmation of safety is neces-
sary.
Over reliance on this function may
lead to an accident resulting
death or serious injury.
