●Changes in the vehicle posture
• If the vehicle is significantly tilted
• If the front of the vehicle is raised or lowered due to the ca rried load
• If the orientation of a sensor has been changed due to a collision or other impact
■ If the Intelligent Clearance Sonar function operates unnecessar ily 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 brak e pedal.
Depressing the accelerator pedal again will allow you to procee d forward and
leave the area.
■ Situations in which the Intell igent Clearance Sonar Brake funct ion 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 sands torm
● 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
3304-5. Using the driving support systems
●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 wir eless 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 ca rried load
• If the orientation of a sensor has been changed due to a collision or other impact
■ If a 12-volt battery terminal has been disconnected and reconne cted
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 war ning 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 batt ery terminal
was disconnected and reconnected. Initialize the system. (P. 330)

WARNING
■Limitations of the Intelligent Clearance Sonar system
Do not overly rely on the system, as doing so may lead to an ac cident.
● The driver is solely responsible for safe driving. Always drive carefully, tak-
ing care to observe your surroundings. The Intelligent Clearanc e 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 ve hicle, it is
necessary to depress the brake pedal immediately as brake contr ol will be
canceled after approximately 2 seconds.
■ To ensure the Intelligent Clearan ce Sonar system can operate properly
Observe the following precautions regarding the sensors ( P. 322). Failure
to do so may cause a sensor to not operate properly, and may ca use 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 imp act.
● Do not damage the sensors, and always keep them clean.
Observe the following precautions regarding the radar sensors ( P. 300).
Failure to do so may cause a radar sensor to not operate proper ly, and may
cause an accident.

3565-1. Using the air conditioning system and defogger
■Using automatic mode
Fan speed is adjusted automatically according to the temperatur e setting and
the ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow
immediately after is pressed.
■ Operation of the air condit ioning system in S-FLOW mode
If the front passenger’s door or a rear door is opened then clo sed, the air con-
ditioning system determines that a passenger is in the vehicle. In this case,
priority for the airflow will be changed from the driver’s seat only to the front
seats only or all seats, respectively. (Depending on the set temperature or
ambient temperature, priority for the airflow may not be given to the driver’s
seat only.)
If a passenger is judged to be in the vehicle, the system will retain the judge-
ment for a certain amount of time after the power switch is tur ned off.
