■Re-enabling the Intelligent Clearance Sonar system
To re-enable the Intelligent Clearance Sonar system when it is disabled due
to operation of the Intelligent Clearance Sonar function, either enable the sys-
tem again (P. 287), or turn the engine switch off and then back to IGNITION
ON mode.
Additionally, if the object becomes no longer in the traveling direction of the
vehicle or if the traveling direction of the vehicle changes (such as changing
from moving forward to backing up, or from backing up to moving forward),
the system will be re-enabled automatically.
■Objects that the Intelligent Clearance Sonar function may not detect
The sensors may not be able to detect certain objects, such as the following.
●Cotton cloth, snow, and other materials that are poor reflectors of ultrasonic
waves.
(People may also not be detected depending on the type of clothing they are
wearing.)
●Objects which are not perpendicular to the ground, are not perpendicular to

■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.

2984-5. Using the driving support systems
If the Rear Cross Traffic Auto Brake function detects that a collision
with an approaching vehicle is possible, the engine output will be
restricted to restrain any increase in vehicle speed. (Engine output
restriction control: See A below.)
Additionally, if the accelerator pedal continues to be depressed, the
brakes will be applied automatically to reduce the vehicle speed.
(Brake control: See B below.)

■The Rear Cross Traffic Auto Brake function will operate when
The function will operate when the ICS OFF indicator is not illuminated or
flashing (P. 287, 295) and all of the following conditions are met:
●Engine output restriction control
• The Intelligent Clearance Sonar with Rear Cross Traffic Auto Brake is
enabled.
• The vehicle speed is 10 mph (15 km/h) or less.
• Vehicles which are approaching from the right or left at the rear of the
vehicle at a traveling speed of less than approximately 5 mph (8 km/h)
• The shift lever is in R.
• The system determines that a stronger than normal brake operation is
necessary to avoid a collision with an approaching vehicle.
●Brake control
• Engine output restriction control is operating.
• The system determines that an emergency brake operation is necessary
to avoid a collision with an approaching vehicle.
■The Rear Cross Traffic Auto Brake function will stop operating when
The function will stop operating if any of the following conditions are met:
●Engine output restriction control
• The Intelligent Clearance Sonar with Rear Cross Traffic Auto Brake is
disabled.
• The collision becomes avoidable with normal brake operation.
• A vehicle is no longer approaching from the right or left at the rear of the
vehicle.
●Brake control
• The Intelligent Clearance Sonar with Rear Cross Traffic Auto Brake is
disabled.
• Approximately 2 seconds elapse after the vehicle is stopped by brake
control.
• The brake pedal is depressed after the vehicle is stopped by brake con-
trol.
• A vehicle is no longer approaching from the right or left at the rear of the
vehicle.
■Detection area of the Rear Cross Traffic Auto Brake function
The detection area of the Rear Cross Traffic Auto Brake function differs from
the detection area of the RCTA function (P. 269).
Therefore, even if the RCTA function detects a vehicle and provides an alert,
the Rear Cross Traffic Auto Brake function may not start operating.
■If the Rear Cross Traffic Auto Brake function has operated
If the vehicle is stopped due to operation of the Rear Cross Traffic Auto Brake
function, the Rear Cross Traffic Auto Brake function will be disabled and the
ICS OFF indicator will illuminate.
