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 will resolve
this problem.)
●The sensor is frozen. (Thawing the area will resolve this problem.)
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.

●The vicinity of the vehicle is noisy due to vehicle horns, motorcycle
engines, air brakes of large vehicles, or other loud noises producing 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.

■Situations in which the Intelligent Clearance Sonar function may operate
even if there is no possibility of a collision
In some situations such as the following, the Intelligent Clearance Sonar
function may operate even though there is no possibility of a collision.
●Vehicle surroundings
• When driving toward a banner, flag, low-hanging branch or boom barrier
(such as those used at railroad crossings, toll gates and parking 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 for 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 sandstorm
●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 wireless 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

●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 wireless 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 carried load
• If the orientation of a sensor has been changed due to a collision or other
impact
■If a battery terminal has been disconnected and reconnected
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 battery terminal was dis-
connected and reconnected. Initialize the system. (P. 295)
If this message continues to be displayed even after initialization, have the
vehicle inspected by your Toyota dealer.
■If “ICS Unavailable” and “Parking Assist Unavailable Clean Parking
Assist Sensor” are displayed on the 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 shown when
the sensor was not dirty to begin with, have the vehicle inspected at your
Toyota dealer.
●A sensor may be frozen. Once the ice melts, the system will return 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.
