together.
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.

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 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.

■Situations in which the system
may not operate properly
●Some pedestrians, such as the
following, may not be detected by
the rear camera detection func-
tion, preventing the function from
operating properly:
• Pedestrians who are bending for- ward or squatting
• Pedestrians who are lying down
• Pedestrians who are running
• Pedestrians who suddenly enter the detection area
• People riding a bicycle, skate- board, or other light vehicle
• Pedestrians wearing oversized clothing such as a rain coat, long
skirt, etc., making their silhouette
obscure
• Pedestrians whose body is par- tially hidden by an object, such as
a cart or umbrella
• Pedestrians which are obscured by darkness, such as at night
●In some situations, such as the
following, pedestrians may not be
detected by the rear camera
detection function, preventing the
function from operating properly:
• When backing up in inclement weather (rain, snow, fog, etc.)
• When the rear camera is
obscured (dirt, snow, ice, etc., are
attached) or scratched
• When a very bright light, such as the sun, or the headlights of
another vehicle, shines directly
into the rear camera
• When backing up in a place where the surrounding brightness
changes suddenly, such as at the
entrance or exi t of a garage or
underground parking lot
• When backing up in a dim envi-
ronment such as during dusk or in
an underground parking lot
• When the camera position and
direction are deviated
• When a towing hook is attached
• When water droplets are flowing on the camera lens
• When the vehicle height is extremely changed (nose up,
nose down).
• When tire chains or an emergency tire puncture repair kit is used
• When the rear washer is operating
• If the suspension has been modi- fied or tires of a size other than
specified are installed.
• If an electronic component, such as a backlit license plate or rear
fog light, is insta lled near the rear
camera
• If a bumper protector, such as an
additional trim strip, is installed to
the rear bumper
■Situations in which the system
may operate unexpectedly
●Even though there are no pedes-
trians in the detection area, some
objects, such as the following,
may be detected, possibly caus-
ing the rear cam era detection
function to operate.
• Three dimensional objects, such as a pole, traffic cone, fence, or
parked vehicle
• Moving objects, such as a car or motorcycle
• Objects moving to ward your vehi-
cle when backing up, such as
flags or puddles (or airborne mat-
ter, such as smoke, steam, rain, or
snow)
• Cobblestone or gravel roads, tram rails, road repai rs, white lines,
pedestrian crossings or fallen

WARNING
■Cautions regarding the use of
the system
Do not overly rely on the system,
as doing so may lead to an acci-
dent.
Always drive while checking the
safety of the surroundings of the
vehicle.
Depending on the vehicle and
road conditions, weather, etc., the
system may not operate.
The detection capa bilities of sen-
sors and radars are limited.
Always drive while checking the
safety of the surroundings of the
vehicle.
●The driver is solely responsible
for safe driving. Always drive
carefully, taking care to observe
your surroundings. The Parking
Support Brake system is
designed to provide support to
lessen the severity of collisions.
However, it may not operate in
some situations.
●The Parking Support Brake sys-
tem is not designed to stop the
vehicle completely. Additionally,
even if the system has stopped
the vehicle, it is necessary to
depress the brake pedal imme-
diately as brake control will be
canceled after approximately 2
seconds.
●It is extremely dangerous to
check the system operations by
intentionally driving the vehicle
into the direction of a wall, etc.
Never attempt such actions.
■When to disable the Parking
Support Brake
In the following situations, disable
the Parking Suppor t Brake as the
system may opera te even though
there is no possibility of a colli-
sion.
●When inspecting the vehicle
using a chassis roller, chassis
dynamo or free roller
●When loading the vehicle onto a
boat, truck or other transport
vessel
●If the suspension has been
modified or tires of a size other
than specified are installed
●If the front of the vehicle is
raised or lowered due to the
carried load
●When equipment that may
obstruct a sensor is installed,
such as a towing eyelet, bumper
protector (an additional trim
strip, etc.), bicycle carrier, or
snow plow
●When using automatic car
washing devices
●If the vehicle cannot be driven in
a stable manner, such as when
the vehicle has been in an acci-
dent or is malfunctioning
●When the vehicle is driven in a
sporty manner or off-road
●When the tires are not properly
inflated
●When the tires are very worn

■If the Parking Support Brake
has operated
If the vehicle is stopped due to oper-
ation of the Parki ng Support Brake,
the Parking Suppor t Brake will be
disabled and the driving assist infor- mation indicator will illuminate. If the
Parking Support Brake operates
unnecessarily, brake control can be
canceled by depre
ssing the brake
pedal or waiting for approximately 2
seconds for it to automatically be
canceled. Then, the vehicle can be
operated by depressing the acceler-
ator pedal.
■Re-enabling the Parking Sup-
port Brake
To re-enable the Parking Support
Brake when it has been disabled
due to operation of the Parking Sup-
port Brake, either enable the system
again ( P.333), or turn the power
switch off and then back to ON.
Additionally, if a ny of the following
conditions are m et, the system will
be re-enabled automatically and the
driving assist inf ormation indicator
will turn off:
●The P shift position is selected
●The object is no longer detected in
the traveling direction of the vehi-
cle
●The traveling direction of the vehi-
cle changes*
*
: Except when the pedestrian rear of the vehicle operated.
■Intuitive parkin g assist-sensor
buzzer
Regardless of whethe r the intuitive
parking assist-s ensor buzzer is
enabled or not, if the PKSB (Parking
Support Brake) system is enabled,
the front or rear s ensors detect a
static object and brake control is
performed, the intuitive parking
assist-sensor bu zzer will sound to
notify the driver o f the approximate
distance to the object.
■If a 12-volt battery terminal has
been disconnected and recon-
nected
The system needs to be initialized.
To initialize the system, drive the
vehicle straight ahead for 5 seconds
or more at a speed of approximately
