WARNING
■Obstacles which may not be properly detected
The shape of the obstacle may prevent a sensor from detecting it. 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
● 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 t\
o a
sensor malfunction, etc. Have the vehicle checked by your Toyota 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
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 area.
Doing so may result in the sensor malfunctioning.

3124-5. Using the driving support systems
The system will operate in situations 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 may occur due to the vehicle sud-
denly moving forward due to an accidental accelerator pedal
operation, the vehicl e moving the unintended direction due to
the wrong shift position being sele cted, or while parking or trav-
eling at low speeds, the sensors detect objects, such as a wall,
in the traveling direction of the vehicle, and the system operates
to lessen an impact with an object and reduce the resulting dam-
age.
Examples of system operation

3144-5. Using the driving support systems
If a radar sensor detects a vehicle approaching from the right or left at
the rear of the vehicle and a collision may occur, this function will per-
form brake control to reduce the likelihood of an impact with the
approaching vehicle.
■Examples of system operation
The system will operate in situati ons such as the following if an
object is detected in the trav eling direction of the vehicle.
◆When reversing, a vehicle is approaching and the brake pedal
is not depressed, or is depressed late

■Re-enabling the Intelligent Clearance Sonar system
To re-enable the Intelligent Clearance Sonar system when it is disabled due
to operation of the Intelligent Clearance Sonar function, either enable the sys-
tem again (→P. 315), or turn the power switch off and then back to ON mode.
Additionally, if the object becomes no longer in the traveling direction of the
vehicle or if the traveling direction of the vehicle changes (such as changing
from moving forward to backing up, or from backing up to moving forward),
the system will be re-enabled automatically.
■ Objects that the Inte lligent Clearance Sonar function may not detect
The sensors may not be able to detect certain objects, such as the following.
● Cotton cloth, snow, and other materials that are poor reflectors of ultrasonic
waves.
(People may also not be detected depending on the type of clothing they are
wearing.)
● Objects which are not perpendicular to the ground, are not perpendicular to
the traveling direction of the vehicle, are uneven or are waving.
● Low objects
● Thin objects such as wires, fences, ropes and signposts
● Objects that are extremely close to the bumper
■ Intuitive parking assist buzzer
Regardless of whether the intuitive parking assist system is enabled or not
(→P. 304), if the Intelligent Clearance Sonar system is enabled ( →P. 315),
the front or rear sensors detect an object and brake control is performed, the
intuitive parking assist buzzer will sound to notify the driver of the approxi-
mate distance to the object.

■Situations in which the Intelligent Clearance Sonar function may operate
even if there is no possibility of a collision
In some situations such as the following, the Intelligent Clearance Sonar
function may operate even though there is no possibility of a collision.
●Vehicle surroundings
• When driving toward a banner, flag, low-hanging branch or boom barrier
(such as those used at railroad crossings, toll gates and parking lots).
• When driving on a narrow path surrounded by a structure, such as in a
tunnel or on an iron bridge
• When parallel parking
• When there is a rut or hole in the surface of the road
• When driving on a metal cover (grating), such as those used for drainage ditches
• When driving on a steep slope
• If a sensor is hit by a large amount of water, such as when driving on a flooded road
● Weather
• If a sensor is covered with ice, snow, dirt, etc. (when cleared, the system
will return to normal)
• If heavy rain or water strikes a sensor
• When driving in inclement weather such as fog, snow or a sandstorm
● Other ultrasonic waves sources
• When vehicle horns, vehicle detectors, motorcycle engines, air brakes of
large vehicles, the clearance sonar of other vehicles or other devices
which produce ultrasonic waves are near the vehicle
• If a sticker or an electronic component, such as a backlit license plate (especially fluorescent type), fog lights, a fender pole or wireless antenna
is installed near a sensor
• When driving on a narrow road
• When driving on a gravel road or in
an area with tall grass

3224-5. Using the driving support systems
●Changes in the vehicle posture
• If the vehicle is significantly tilted
• If the front of the vehicle is raised or lowered due to the carried load
• If the orientation of a sensor has been changed due to a collision or other
impact
■ If the Intelligent Clearance Sona r function operates unnecessarily such
as at a railroad crossing
Even in the event that the Intelligent Clearance Sonar function operates
unnecessarily, such as at a railroad crossing, brake control will be canceled
after approximately 2 seconds, allowing you to proceed forward and leave the
area, Brake control can also be canceled by depressing the brake pedal.
Depressing the accelerator pedal again will allow you to proceed forward and
leave the area.
■ Situations in which the Intelligent Clearance Sonar Brake function may
not operate properly
In some situations such as the following, this function may not operate prop-
erly.
●Weather
• If a sensor is covered with ice, snow, dirt, etc. (when cleared, the system
will return to normal)
• If heavy rain or water strikes a sensor
• When driving in inclement weather such as fog, snow or a sandstorm
● Vehicle surroundings
• 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.
• When a sensor or the area around a
sensor is extremely hot or cold
• When strong winds are blowing

●Other ultrasonic waves sources
• When vehicle horns, vehicle detectors, motorcycle engines, air brakes of
large vehicles, the clearance sonar of other vehicles or other devices
which produce ultrasonic waves are near the vehicle
• If a sticker or an electronic component, such as a backlit license plate
(especially fluorescent type), fog lights, a fender pole or wireless antenna
is installed near a sensor
● Changes in the vehicle posture
• If the vehicle is significantly tilted
• If the front of the vehicle is raised or lowered due to the carried load
• If the orientation of a sensor has been changed due to a collision or other
impact
■ If a 12-volt battery terminal h as been disconnected and reconnected
The system needs to be initialized.
To initialize the system, drive the vehicle straight ahead for 5 seconds or more
at a speed of approximately 22 mph (35 km/h) or more.
■ If “ICS Unavailable” is displayed on the multi-information display and
the ICS OFF indicator is flashing
● A sensor may be covered with ice, snow, dirt, etc. Remove the 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 mes-
sage may be displayed or the sensor may not be able to detect an object.
Once the ice melts, the system will return to normal.
● 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 Toyota dealer.
● Initialization may not have been performed after a 12-volt battery terminal
was disconnected and reconnected. Initialize the system. ( →P. 323)
