■ Sensor detection range
The detection range of the Intelligent Clearance Sonar function differs from
the detection range of the intuitive parking assist (P. 433).
Therefore, even if the intuitive parking assist detects an obstacle and pro-
vides a warning, the Intelligent Clearance Sonar may not start operating.
■ System operation
When the vehicle is stopped by system operation, the Intelligent Clearance
Sonar function stops and the ICS OFF indicator illuminates.
■ System recovery
When the Intelligent Clearance Sonar function is stopped by system opera-
tion and you would like to resume operation, either turn the Intelligent Clear-
ance Sonar on again (P. 440), or turn the power switch off and then back
on. Furthermore, when the vehicle moves with an obstacle no longer in the
traveling direction of the vehicle, or when the traveling direction of the vehicle
changes (such as when switching from moving forward to backing up, and
vice versa), system operation automatically resumes.
■ Obstacles not detected by the sensors
The following obstacles may not be detected by the sensors.
● Objects such as people, cloth and snow, that are difficult for sonic waves to
reflect off of. (In particular, people may also not be detected depending on
the type of clothing they are wearing.)
● Objects not perpendicular with the ground, objects not at a right angle to the
traveling direction of the vehicle, uneven objects or waving objects
● 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 is on or off (P. 429), if the
Intelligent Clearance Sonar function is not stopped (P. 440), when the front
or rear sensors detect an obstacle and brake control is performed, the intui-
tive parking assist buzzer also sounds and a notification of the approximate
distance to the obstacle is provided.
