ObjectCalculated 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.
Object detected by side sensors or side cameras
1 The vehicle is stopped and objects along the sides of the vehic le
are not detected.
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 fuel cell 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 multimedia display is dis-
played.
●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 the vehicle has
been driven a small amount and
the side sensors o r 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

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 n ot 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 shown 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 vehic le and cannot
be detected.
●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 Aler t)*
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 o bserve your sur-
roundings.
The RCTA functi on is only a sup-
plementary function which alerts
the driver tha t 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.
