●Wires, fences, ropes, etc.
●Cotton, snow and other materials
that absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections
projecting outwards in the direc-
tion of your vehicle
■Situations in which the system
may not operate properly
Certain vehicle conditions and the
surrounding environment may affect
the ability of a sensor to correctly
detect objects. Particular instances
where this may occur are listed
below.
●There is dirt, snow, water drops or
ice on a sensor. (Cleaning the
sensors will resolve this problem.)
●A sensor is frozen. (Thawing the
area will resolve this problem.)
In especially cold weather, if a
sensor is frozen the sensor dis-
play may be displayed abnormally,
or objects, such as a wall, may not
be detected.
●When a sensor or the area around
a sensor is extremely hot or cold.
●On an extremely bumpy road, on
an incline, on gravel, or on grass.
●When vehicle horns, vehicle
detectors, motorcycle engines, air
brakes of large vehicles, the clear-
ance sonar of other vehicles or
other devices which produce ultra-
sonic 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.
●When a pedestrian is wearing
clothing that does not reflect ultra-
sonic waves (ex. skirts with gath-
ers or frills).
●When objects that are not perpen-
dicular to the ground, not perpen-
dicular 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,
motorcycle, 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 pro-
tector (an additional trim strip,
etc.), bicycle car rier, or snow plow
●If the front of the v ehicle 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
possibility of a collision
In some situations, such as the fol-
lowing, the system may operate
even though there is no possibility of
a collision.
●When driving on a narrow road

2585-5. Using the driving support systems
Owners Manual_USA_M62084_en
●When driving toward a banner,
flag, low-hanging branch or boom
barrier (such as those used at rail-
road crossings, toll gates and
parking lots)
●When there is a rut or hole in the
surface of the road
●When driving on a metal cover
(grating), such as those used for
drainage ditches
●When driving up or down a steep
slope
●If a sensor is hit by a large amount
of water, such as when driving on
a flooded road
●There is dirt, snow, water drops or
ice on a sensor. (Cleaning the
sensors will resolve this problem.)
●A sensor is coated with a sheet of
spray or heavy rain
●When driving in inclement weather
such as fog, snow or a sandstorm
●When strong winds are blowing
●When vehicle horns, vehicle
detectors, motorcycle engines, air
brakes of large vehicles, the clear-
ance sonar of other vehicles or
other devices which produce ultra-
sonic waves are near the vehicle
●If the front of the vehicle is raised
or lowered due to the carried load
●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 parking garages, construc-
tion 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

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 intuitive
parking assist and RCTA func-
tion (if equipped) will be muted
simultaneously. 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.

detect objects. While the vehicle is moving, if a detected object 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 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 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
detection 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 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.
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
There is a limit t o the degree of
recognition accuracy and control
performance that this system can
provide, do not overly rely on this
system. The driver is always
responsible for paying attention to
the vehicle’s su rroundings and
