CAMRY_U (01999-06122)
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 situations 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

CAMRY_U (01999-06122)■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. 325), or turn the engine switch off and then back to IGNITION
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 Intelligent 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. 314), if the Intelligent Clearance Sonar system is enabled (→P. 325),
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.

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

CAMRY_U (01999-06122)●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 Sonar 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

CAMRY_U (01999-06122)●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 battery terminal has 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 battery terminal was dis-
connected and reconnected. Initialize the system. (→P. 333)

WARNING
■Limitations of the Intelligent Clearance Sonar system
Do not overly rely on the system, as doing so may lead to an accident.
●The driver is solely responsible for safe driving. Always drive carefully, tak-
ing care to observe your surroundings. The Intelligent Clearance Sonar
system is designed to provide support to lessen the severity of collisions.
However, it may not operate in some situations.
●The Intelligent Clearance Sonar system is not designed to stop the vehicle
completely. Additionally, even if the system has stopped the vehicle, it is
necessary to depress the brake pedal immediately as brake control will be
canceled after approximately 2 seconds.
■To ensure the Intelligent Clearance Sonar system can operate properly
Observe the following precautions regarding the sensors (→P. 325). Failure
to do so may cause a sensor to not operate properly, and may cause an
accident.
●Do not modify, disassemble or paint the sensors.
●Do not replace a sensor with a part other than a genuine part.
●Do not subject a sensor or its surrounding area to a strong impact.
●Do not damage the sensors, and always keep them clean.
