■Objects which the system may
not be properly detected
The shape of the object may pre-
vent the sensor from detecting it.
Pay particular attention to the follow-
ing objects:
●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
People may not be detected if they
are wearing certain types of cloth-
ing.
■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.)

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 ot her 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

PKSB (Parking Sup-
port Brake)*
The Parking Support Brake
system consists of the fol-
lowing functions that oper-
ate when driving at a low
speed or backing up, such
as when parking. When the
system determines that the
probability of a collision
with a detected object or
pedestrian is high, a warn-
ing operates to urge the
driver to take evasive
action. If the system deter-
mines that the possibility of
a collision with a detected
object or pedestrian is
extremely high, the brakes
are automatically applied to
help avoid the collision or
help reduce the impact of
the collision.

●Brake control
• The Parking Support Brake is dis- abled.
• Approximately 2 seconds have elapsed since the vehicle was
stopped by brake control.
• The brake pedal is depressed after the vehicle is stopped by
brake control.
• A vehicle is no longer approaching from the right or left at the rear of
the vehicle.
■Detection range
The detection area of the moving
vehicles rear of the vehicle differs
from the detection area of the RCTA
function ( P.324). Therefore, even
if the RCTA function detects a vehi-
cle and provides an alert, the mov-
ing vehicles rear of the vehicle may
not start operating.
■RCTA buzzer
Regardless of weather the RCTA
function is on o r off, if the PKSB
(Parking Support Brake) system is
not disabled, when the brake control
operates, the buzze r will sounds to
alert the driver.

If the rear camera sensor
detects a pedestrian behind
the vehicle while backing
up and the system deter-
mines that the possibility of
colliding with the detected
pedestrian is high, a buzzer
will sound. If the system
