• When cleaning the camera lens, flush the camera with a large
quantity of water and wipe it
with a soft and wet cloth.
Strongly rubbing the camera
lens may cause the camera lens
to be scratched and unable to
transmit a clear image.
• Do not allow organic solvent, car wax, window cleaner or
glass coating to adhere to the
camera. If this happens, wipe it
off as soon as possible.
• If the temperature changes rap- idly, such as when hot water is
poured on the vehicle in cold
weather, the system may not
operate normally.
• When washing the vehicle, do not apply intensive bursts of
water to the camera or camera
area. Doing so may result in the
camera malfunctioning.

■Cautions regarding the use of
the system
There is a limit to 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.
●Do not damage the sensors,
and always keep them clean.

■The system can be operated
when
●The engine 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.
■Setting the buzzer volume
The buzzer volume can be adjusted
on the multi-info rmation display.
(  P. 9 4 )
■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.
If a sensor is dirty, the position of the
dirty sensor will be shown on the
display.
Due to ice forming on a sensor at
low temperatures, a warning mes-
sage may be displayed or the sen-
sor 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 is clean, there
may be a sensor malfunction. Have
the vehicle inspect ed by your Toyota
dealer.
■If “Parking Assist Unavailable”
is displayed on the multi-infor-
mation display
Water may be continuously flowing
over the sensor surf ace, such as in
a heavy rain. When the system
WARNING
●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 Toyota dealer. If
the front or rear bumper needs
to be emoved/installed or
replaced, contact a 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.

determines that it is normal, the sys-
tem will return to normal.
■Sensor detection information
●The sensors may be able to only
detect objects near the 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.
• After the static object detection, there will be a short delay before a
graphic is shown on displays, and
warning buzzer sounds. Even at
low speeds, there is a possibility
that the object will come within the
sensor’s detection areas before
the display is shown and the warn-
ing beep 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
buzzer if buzzers for other sys-
tems are sounding.
■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
clothing.
■Situations in which the system
may not operate properly
Certain vehicle conditions and the
surrounding environment may affect
the ability of a sens or to correctly
detect objects. Pa rticular instances
where this may occur are listed
below.
●There is dirt, snow, water drops or
ice on a sensor. (Cleaning the
sensors will resolv e 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.
