denly, such as at the entrance or exit of a tunnel

5-5. Using the driving support systems
■When the sensor may not be correctly detect ing the vehicle ahead
In the case of the following and depending on the conditions, o perate the
brake pedal when deceleration of the system is insufficient or operate the
accelerator pedal when acceleration is required.
As the sensor may not be able to correctly detect these types o f vehicles, the
approach warning ( P. 400) will not be activated.
● Vehicles that cut in suddenly
● Vehicles traveling at low speeds
● Vehicles that are not moving in the same lane
● Vehicles with small rear ends (trailers with no load on board, etc.)
● Motorcycles traveling in the same lane
● When water or snow thrown up by the surrounding vehicles hinders the
detecting of the sensor
●When your vehicle is pointing upwards
(caused by a heavy load in the luggage
compartment, etc.)
● Preceding vehicle has an extremely high
ground clearance

■Sensor detection range
The detection range of the Intelligent Clearance Sonar function differs from
the detection range of the intuitive parking assist ( P. 424).
Therefore, even if the intuitive parking assist detects an obst acle and pro-
vides a warning, the Intelligent Clearance Sonar may not start operating.
■ System operation
When the vehicle is stopped by system operation, the Intelligen t Clearance
Sonar function stops and the ICS OFF indicator illuminates.
■ System recovery
When the Intelligent Clearance Sonar function is stopped by sys tem opera-
tion and you would like to resume operation, either turn the In telligent Clear-
ance Sonar on again ( P. 431), or turn the power switch off and then back
on. Furthermore, when the vehicle moves with an obstacle no lon ger in the
traveling direction of the vehicle, or when the traveling direc tion 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 rig ht 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. 420), if the
Intelligent Clearance Sonar function is not stopped ( P. 431), when the front
or rear sensors detect an obstacle and brake control is perform ed, the intui-
tive parking assist buzzer also sounds and a notification of th e approximate
distance to the obstacle is provided.
