Sensor detection information
●The sensor’s detection areas are limited to the areas around th e vehicle’s
bumper.
● Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctly detect an obstacle. Particular instances where
this may occur are listed below.
• There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve
this problem.)
• The sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen the screen ma y show an
abnormal display, or obstacles may not be detected.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle
engines, air brakes of large vehicles, or other loud noises pro ducing ultra-
sonic waves.
• There is another vehicle equipped with parking assist sensors in the
vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna .
• Towing eyelets are installed.
• The bumper or sensor receives a strong impact.
• A backlit license plate, license plate holder, etc., are insta lled.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is not detected.
• If obstacles draw too close to the sensor.
• A non-genuine Toyota suspension (lowered suspension etc.) is i nstalled.
• People may not be detected if they are wearing certain types o f clothing.
In addition to the examples above, there are instances in which, because of
their shape, signs and other objects may be judged by a sensor to be closer
than they are.
● The shape of the obstacle may prevent a sensor from detecting i t. Pay par-
ticular attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of your vehicle

MIRAI_OM_USA_OM62073U●
The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection
distance may shorten, or detection may be impossible.
• Obstacles may not be detected if they are too close to the sen sor.
• There will be a short delay between obstacle detection and dis play. Even
at slow speeds, there is a possibility that the obstacle will c ome within the
sensor’s detection areas before the display is shown and the bu zzer
sounds.
• Thin posts or objects lower than the sensor may not be detecte d when
approached, even if they have been detected once.
• It might be difficult to hear beeps due to the volume of audio system or air
flow noise of the air conditioning system.
■ Muting the buzzer sound
●To mute the buzzer sound
The buzzer can be temporarily muted by pressing of the meter c ontrol
switches while an obstacle detection display is shown on the mu lti-informa-
tion display.
● To cancel the mute
Mute will be automatically canceled in the following situations .
• When the shift position is changed
• When the vehicle speed has reac hed or exceeded approximately 6 mph
(10 km/h)
• When the intuitive parking assist is turned off once and turned on again
• When the power switch is turned off once and turned to ON mode again
• When a sensor is malfunctioning
■ If “Parking Assist Unavailable Clean Parking Assist Sensor” is displayed
on the multi-information display
A sensor may be dirty or covered with snow or ice. In such case s, if it is
removed from the sensor, the system should return to normal.
Also, due to the sensor being frozen at low temperatures, a mal function dis-
play may appear or an obstacle may not be detected. If the sens or thaws out,
the system should return to normal.
■ If “Parking Assist Malfunction Visit Your Dealer” is displayed on the
multi-information display
Depending on the malfunction of the sensor, the device may not be working
normally.
Have the vehicle inspected by your Toyota dealer.
■ Customization
Some functions can be customized.

WARNING
■When using the intuitive parking assist
Observe the following precautions.
Failing to do so may result in the vehicle being unable to be d riven safely
and possibly cause an accident.
● Do not use the sensor at speeds in excess of 6 mph (10 km/h).
● The sensors’ detection areas and reaction times are limited. When moving
forward or reversing, check the areas surrounding the vehicle ( especially
the sides of the vehicle) for safety, and drive slowly, using t he brake to
control the vehicle’s speed.
● Do not install accessories within the sensors’ detection areas.
NOTICE
■When using intuitive parking assist
In the following situations, the system may not function correctly due to a
sensor malfunction, etc. Have the vehicle checked by your Toyot a dealer.
● The intuitive parking assist operation display flashes, and a buzzer sounds
when no obstacles are detected.
● If the area around a sensor collides with something, or is subjected to
strong impact.
● If the bumper collides with something.
● If the display shows continuously without beeping, except when the buzzer
mute switch has been turned on.
● If a display error occurs, first check the sensor.
If the error occurs even if there is no ice, snow or mud on the sensor, it is
likely that the sensor is malfunctioning.
■ Notes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor a rea.
Doing so may result in the sensor malfunctioning.

When the Parking Support
Brake function (for static
objects) is OFF (disabled), the

When switched OFF (disable) and
the Parking Support Brake function

When the Parking Support Brake function (for static objects) de tects
an static obstacle with a probab ility of collision, the fuel cell system
output is restricted to restrain an increase in vehicle speed. (fuel cell

Furthermore, when the accelerator pedal continues to be depress ed,
the brakes are applied to reduce the vehicle speed. (Brake Control: B)

Influence from other sonic waves
• An ultrasonic wave source is nearby, such as the horn or parki ng assist
system of another vehicle, a vehicle detector, a motorcycle eng ine or the
air brake of a large vehicle
• Electronic components (such as a backlit license plate [especi ally fluores-
cent types], fog lights, a fender pole or a wireless antenna) a re installed
near the sensors
● Changes in the vehicle
• The vehicle is tilted a large amount
• The height of the vehicle has drastically changed due to the c arried load
(the nose tilts up or down)
• The direction of the sensor has deviated due to a collision or other impact
■ When removing and instal ling the 12-volt battery
The system needs to be initialized.
The system can be initialized by driving the vehicle straight a head for 5 sec-
onds or more at a speed of approximately 22 mph (35 km/h) or hi gher.
■ When “PKSB Unavailable” is displayed on the multi-information display
and the PKSB OFF indicator flashes
●Ice, snow, dirt, etc., may have adhered to the sensor. If this occurs, remove
the ice, snow, dirt, etc., from the sensor to return the system to normal.
Also, a warning message may be displayed at low temperatures du e to ice
forming on the sensor, and the sensor may not detect obstacles. Once the
ice melts, the system will return to normal.
● If this message is shown even after removing dirt from the sensor, or shown
when the sensor was not dirty to begin with, have the vehicle i nspected at
your Toyota dealer.
● System initialization may not have been performed after removal and instal-
lation of the 12-volt battery. Perform system initialization.
■ When “PKSB Malfunction Visit Your Dealer” is displayed on the m ulti-
information display, the PKSB OFF indicator flashes and the buz zer
sounds
The system may not be operating properly. Have the vehicle inspected at
your Toyota dealer.
