■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

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)

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*

■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

3365-4. Using the driving support systems

*: If equipped
This function will operate in situ-
ations such as the following if an
object is detected in the travel-
ing direction of the vehicle.
Static Objects Front
and Rear of the Vehi-
cle
*
If the sensors detect a static
object, such as a wall, in the
traveling direction of the
vehicle and the system
determines that a collision
may occur due to the vehi-
cle suddenly moving for-
ward due to an accidental
accelerator pedal operation,
the vehicle moving the
unintended direction due to
the wrong shift position
being selected, or while
parking or traveling at low
speeds, the system will
operate to lessen the impact
with the detected static
object and reduce the
resulting damage.
