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.
Observe the following precautions regarding the radar sensors (→P. 303).
Failure to do so may cause a radar sensor to not operate properly, and may
cause an accident.
●Do not modify, disassemble or paint the sensors.
●Do not replace a radar sensor with a part other than a genuine part.
●Do not subject a radar sensor or its surrounding area to a strong impact.
●Do not damage the radar sensors, and always keep the radar sensors and
their surrounding area on the bumper clean.
■Handling the suspension
Do not modify the suspension, as changes to the height or inclination of the
vehicle may prevent the sensors from detecting objects correctly or cause
the system to not operate or operate unnecessarily.

NOTICE
■To prevent the system from malfunctioning
●If the area around a sensor is subjected to an impact, the system may not
operate properly due to the sensor being misaligned. Have the vehicle
inspected by your Toyota dealer.
●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 malfunction.
■To prevent a radar sensor from malfunctioning
●If the area around a radar sensor is subjected to an impact, the system
may not operate properly due to a sensor malfunction. Have the vehicle
inspected by your Toyota dealer.
●Observe the radar sensor handling precautions. (→P. 303)
■To prevent unnecessary operation of the Intelligent Clearance Sonar
system
In the following situations, disable the Intelligent Clearance Sonar system
as the system may operate even though there is no possibility of a collision.
●When inspecting the vehicle using a chassis roller, chassis dynamo or free
roller
●When loading the vehicle onto a boat, truck or other transport vessel
●If the suspension has been modified or tires of a size other than specified
are installed
