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’ surroundings and
driving safely.
■To ensure the system can
operate properly
Observe the following precau-
tions.
Failing to do so may result in the
vehicle being unable to be driven
safely and possibly cause an acci-
dent.

Driving
■The system can be operated
when
●The power switch is in ON.
●Intuitive parking assist function is
on.
●The vehicle speed is less than
about 6 mph (10 km/h).
●A shift position other than P is
selected.
■If “Clean Parking Assist Sen-
sor” is displayed on the multi-
information display
A sensor may be covered with water
drops, ice, snow, dirt, etc. Remove
the water drops, ice, snow, dirt, etc.,
from the sensor to return the system
to normal.
Also, due to ice forming on a sensor
at low temperatures, a warning
message may be displayed or the
sensor may not be able to detect an
object. Once the ice melts, the sys-
tem will return to normal.
If a warning message is displayed
even if the sensor i s clean, there
may be a sensor malfunction. Have
the vehicle inspected by your Toyota
dealer.
WARNING
●Do not damage the sensors,
and always keep them clean.
●Do not attach a sticker or install
an electronic component, such
as a backlit license plate (espe-
cially fluorescent type), fog
lights, fender pole or wireless
antenna near a radar sensor.
●Do not subject the surrounding
area of the sensor to a strong
impact. If subjected to an
impact, have the vehicle
inspected by your Toyota
dealer. If the fr ont or rear
bumper needs to be
emoved/installed or replaced,
contact your Toyota dealer.
●Do not modify, disassemble or
paint the sensors.
●Do not attach a license plate
cover.
●Keep your tires properly
inflated.
■When to disable the function
In the following situations, disable
the function as it may operate
even though there is no possibility
of a collision.
●Failing to observe the warnings
above.
●A non-genuine Toyota suspen-
sion (lowered suspension, etc.)
is installed.
■Notes when washing the vehi-
cle
Do not apply intensive bursts of
water or steam to the sensor
area.
Doing so may result in the sensor
malfunctioning.
●When using a high pressure
washer to wash the vehicle, do
not spray the sensors directly,
as doing so may cause a sensor
to malfunction.
●When using steam to clean the
vehicle, do not direct steam too
close to the sensors as doing so
may cause a sensor to malfunc-
tion.

■If “Parking Assist Unavailable”
is displayed on the multi-infor-
mation display
Water may be continuously flowing
over the sensor surface, such as in
a heavy rain. When the system
determines that it is normal, the sys-
tem will return to normal.
■Sensor detection information
●The sensor’s detection areas are
limited to the areas around the
vehicle’ front and rear bumpers.
●The following situations may occur
during use.
• Depending on the shape of the object and other factors, the
detection distance may shorten, or
detection may be impossible.
• Detection may be impossible if
static objects draw too close to the
sensor.
• There will be a short delay
between static object detection
and display (warning buzzer
sounds). Even at low speeds,
there is a possibilit y that the object
will come within 11.9 in. (30 cm)
before the display is shown and
the warning buzzer sounds.
• It might be difficult to hear the buzzer due to the volume of the
audio system or air flow noise of
the air conditioning system.
• It may be difficult to hear the
sound of this system due to the
buzzers of other systems.
■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
■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. Part icular 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 froz en. (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 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

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 betw een 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 t o a collision or
other impact
●When equipment that may
obstruct a sensor is installed, such
as a towing eyelet, bumper pro-
tector (an additi onal trim strip,
etc.), bicycle carrier, or snow plow
●If the front of the vehicle 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
●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 ru
t 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.)

cator is on
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 PKSB OFF indica-
tor will illuminate.
●A sensor may be covered with
water drops, ice, snow, dirt, etc.
Remove the water drops, ice,
snow, dirt, etc., from the sensor to
return the system to normal.
Also, due to ice forming on a sen-
sor at low temperatures, a warn-
ing message may be displayed or
the sensor may n ot be able to
detect an object. Once the ice
melts, the system will return to
normal.
●If this message is displayed only
when the R shift position is
selected, the rear camera lens
may be dirty. Clean the camera
lens. If this message is displayed
when the shift position is any posi-
tion other than R, a sensor on the
front or rear bumper may be dirty.
Clean the sensors and their sur-
rounding area on the bumpers.
●If this message continues to be
displayed even after cleaning the
sensor, or is displayed even
though the sensor is clean, have
the vehicle inspected by your Toy-
ota dealer.
■Intuitive parking assist buzzer
Regardless of whether the Intuitive
parking assist buzzer is enabled or
not, if the PKSB ( Parking Support
Brake) system is enabled, the front
or rear sensors detect a static object
and brake control is performed, the
Intuitive parking assist buzzer will
sound to notify the driver of the
approximate distanc e to the object.

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.
