WARNING
■Sensors
Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctly detect an object. Particular instances where
this may occur are listed below.
● There is dirt, snow or ice on the sensor. (Wiping the sensors w ill resolve
this problem.)
● The sensor is frozen. (Thawing the area will resolve this probl em.)
In especially cold weather, if a sensor is frozen the screen may show an
abnormal display, or objects may not be detected.
● The sensor is covered in any way.
● The vehicle is leaning considerably to one side.
● On an extremely bumpy road, on an incline, on gravel, or on grass.
● The vicinity of the vehicle is noisy due to vehicle horns, moto rcycle
engines, air brakes of large vehicles, or other loud noises pro ducing ultra-
sonic waves.
● There is another vehicle equipped with parking assist sensors in the vicin-
ity.
● The sensor is coated with a sheet of spray or heavy rain.
● The sensor is drenched with water on a flooded road.
● The vehicle is equipped with a fender pole or wireless antenna.
● Towing eyelets are installed.
● The bumper or sensor receives a strong impact.
● The vehicle is approaching a tall or curved curb.
● The detection range is reduced due to an object such as a sign.
● In harsh sunlight or intense cold weather.
● The area directly under the bumpers is not detected.
● If objects draw too close to the sensor.
● A non-genuine Toyota suspension (lowered suspension, etc.) is installed.
● A backlit license plate is installed.
In addition to the examples above, there are instances in which , because of
their shape, signs and other objects may be judged by a sensor to be closer
than they are.

3304-5. Using the driving support systems
■Situations in which the Intellige nt Clearance Sonar function ma y operate
even if there is no possibility of a collision
In some situations such as the following, the Intelligent Clear ance Sonar
function may operate even though there is no possibility of a c ollision.
● Vehicle surroundings
• When driving toward a banner, flag, low-hanging branch or boom barrier
(such as those used at railroad crossings, toll gates and parki ng 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 fo r 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 sands torm
● 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
• When driving on a narrow road
• When driving on a gravel road or in
an area with tall grass

3324-5. 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
Initialization may not have been performed after a 12-volt battery terminal
was disconnected and reconnected. Initialize the system. ( P. 332)
If this message continues to be displayed even after initializa tion, have the
vehicle inspected by your Toyota dealer.
■ If “ICS Unavailable” and “Parking Assist Unavailable Clean Park ing
Assist Sensor” are displayed on th e multi-information display and the
ICS OFF indicator is flashing
● A sensor may be covered with ice, snow, dirt, etc. In this case , remove the
ice, snow, dirt, etc., from the sensor to return the system to normal. If this
message is shown even after removing dirt from the sensor, or s hown when
the sensor was not dirty to begin with, have the vehicle inspec ted at your
Toyota dealer.
● A sensor may be frozen. Once the ice melts, the system will ret urn to nor-
mal.
● Water may be continuously flowing over the sensor surface, such as in a
heavy rain. When the system determines that it is normal, the system will
return to normal.
