■Buzzer operation and distance to an obstacle
A buzzer sounds when the sensors are operating.
● The buzzer sounds faster as the vehicle approaches an obstacle.
When the vehicle comes within the following distance of the
obstacle, the buzzer sounds continuously: Approximately 1.2 ft.
(35 cm).
● When 2 or more obstacles are detected simultaneously, the
buzzer system responds to the nearest obstacle. If one or both
come within the above distances , the beep will repeat a long
tone, followed by fast beeps.
Approximately 3.3 ft. (100 cm)
Approximately 4.9 ft. (150 cm)
Approximately 2.6 ft. (80 cm)
The diagram shows the detection
range of the sensors. Note that the
sensors cannot detect obstacles
that are extremely close to the
vehicle.
The range of the sensors may
change depending on the shape of
the object, etc.

■The intuitive parking assist can be operated when
●Front corner sensors:
• The power switch is in ON mode.
• The shift lever is in other than P.
• The vehicle speed is less than about 6 mph (10 km/h).
● Front center sensors:
• The power switch is in ON mode.
• The shift lever is in other than P or R.
• The vehicle speed is less than about 6 mph (10 km/h).
● Rear corner and rear center sensors:
• The power switch is in ON mode.
• The shift lever is in R.
• The vehicle speed is less than about 6 mph (10 km/h).
■ Intuitive parking assist display
When an obstacle is detected while the Toyota parking assist monitor or pan-
oramic view monitor is in use, the warning indicator will appea r in the upper
part of the screen even if the display setting has been set to off.

■Sensor detection information
●The sensor’s detection areas are limited to the areas around th e vehicle’s
bumper.
● Depending on the shape of the obstacle and other factors, the d etection dis-
tance may shorten, or detection may be impossible.
● Obstacles may not be detected if they are too close to the sens or.
● There will be a short delay between obstacle detection and display. Even at
slow speeds, there is a possibility that the obstacle will come within the sen-
sor’s detection areas before the display is shown and the buzze r sounds.
● Thin posts or objects lower than the sensor may not be detected 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.
■ If “Parking Assist Unavailable Please Clean Parking Assist Sens or” 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.
■ Customization
Some functions can be customized. ( P. 105, 523)
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.

2924-5. Using the driving support systems
WARNING
■Sensors
Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctl y detect an obstacle. Particular instances where
this may occur are listed below.
● There is dirt, snow or ice on the sensor. (Wiping the sensors w ill resolve
this problem.)
● The sensor is frozen. (Thawing the area will resolve this probl em.)
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 gra ss.
● The vicinity of the vehicle is noisy due to vehicle horns, moto rcycle
engines, air brakes of large vehicles, or other loud noises pro ducing ultra-
sonic waves.
● There is another vehicle equipped with parking assist sensors i n the vicin-
ity.
● The sensor is coated with a sheet of spray or heavy rain.
● The sensor is drenched with water on a flooded road.
● The vehicle is equipped with a fender pole or wireless antenna.
● Towing eyelets are installed.
● The bumper or sensor receives a strong impact.
● The vehicle is approaching a tall or curved curb.
● The detection range is reduced due to an object such as a sign.
● 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.
● A backlit license plate is installed.
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.

WARNING
■Obstacles which may not be properly detected
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 d irection of
your vehicle
● People may not be detected if they are wearing certain types of clothing.
● Moving objects such as people or animals
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 b uzzer 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
volume is muted.
● 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.

2944-5. Using the driving support systems
The system will operate in situat ions such as the following if an object
is detected in the traveling direction of the vehicle.
◆When traveling at a low speed and the brake pedal is not
depressed, or is depressed late
Intelligent Clearance Sonar (ICS)
: If equipped
If a collision with an object ma y occur due to the vehicle sud-
denly moving forward due to an accidental accelerator pedal
operation, the vehicle moving th e unintended direction due to
the wrong shift position being se lected, or while parking or trav-
eling at low speeds, the sensors detect objects, such as a wall ,
in the traveling direction of t he vehicle, and the system opera tes
to lessen an impact with an object and reduce the resulting dam -
age.
Examples of system operation

2964-5. Using the driving support systems
If a radar sensor detects a vehi cle approaching from the right or left at
the rear of the vehicle and a collision may occur, this functio n will per-
form brake control to reduce th e likelihood of an impact with the
approaching vehicle.
■Examples of system operation
The system will operate in situat ions such as the following if an
object is detected in the traveling direction of the vehicle.
◆When reversing, a vehicle is approaching and the brake pedal
is not depressed, or is depressed late
