■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

3144-5. 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 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 term inal was dis-
connected and reconnected. Initialize the system. ( P. 314)
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.

If the Rear Cross Traffic Auto Brake function detects that a collision
with an approaching vehicle is pos sible, the engine output will be
restricted to restrain any incre ase in vehicle speed. (Engine output
restriction control: See A below.)
Additionally, if the accelerator pedal continues to be depresse d, the
brakes will be applied automatically to reduce the vehicle spee d.
(Brake control: See B below.)

■The Rear Cross Traffic Auto Br ake function will operate when
The function will operate when the ICS OFF indicator is not ill uminated or
flashing ( P. 306, 314) and all of the following conditions are met:
● Engine output restriction control
• The Intelligent Clearance Sonar with Rear Cross Traffic Auto B rake is
enabled.
• The vehicle speed is 10 mph (15 km/h) or less.
• Vehicles which are approaching from the right or left at the r ear of the
vehicle at a traveling speed of approximately 5 mph (8 km/h) or more.
• The shift lever is in R.
• The system determines that a stronger than normal brake operat ion 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 nec essary
to avoid a collision with an approaching vehicle.
■ The Rear Cross Traffic Auto Br ake function will stop operating when
The function will stop operating if any of the following condit ions are met:
● Engine output restriction control
• The Intelligent Clearance Sonar with Rear Cross Traffic Auto B rake is
disabled.
• The collision becomes avoidable with normal brake operation.
• A vehicle is no longer approaching from the right or left at t he rear of the
vehicle.
● Brake control
• The Intelligent Clearance Sonar with Rear Cross Traffic Auto B rake 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 b rake con-
trol.
• A vehicle is no longer approaching from the right or left at t he rear of the
vehicle.
■ Detection area of the Rear Cro ss 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. 288).
Therefore, even if the RCTA function detects a vehicle and provides an alert,
the Rear Cross Traffic Auto Brake function may not start operat ing.
■ If the Rear Cross Traffic Auto Brake function has operated
If the vehicle is stopped due to operation of the Rear Cross Tr affic Auto Brake
function, the Rear Cross Traffic Auto Brake function will be di sabled and the
ICS OFF indicator will illuminate.

again ( P. 306), or turn the engine switch off and then back to IGNITIO N ON
mode. When the function is disabled, the ICS OFF indicator will illuminate.
( P. 87)
If there is no longer a vehicle approaching from the right or l eft at the rear of
the vehicle when backing up, or if the traveling direction of the vehicle
changes (such as changing from backing up to moving forward), the system
will be re-enabled automatically. When the function is re-enabl ed, the ICS
OFF indicator will turn off.
■ Conditions under which the Rear Cross Traffic Auto Brake function will
not detect a vehicle

■Sounds and vibrations caused by the ABS, brake assist, VSC, TRA C and
hill-start assist control systems
● A sound may be heard from the engine compartment when the brake pedal
is depressed repeatedly, when the engine is started or just aft er the vehicle
begins to move. This sound does not indicate that a malfunction has
occurred in any of these systems.
● Any of the following conditions may occur when the above system s are
operating. None of these indicates that a malfunction has occur red.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard also after the vehicle comes to a s top.
• The brake pedal may pulsate slightly after the ABS is activate d.
• The brake pedal may move down slightly after the ABS is activa ted.
■ EPS operation sound
When the steering wheel is operated, a motor sound (whirring so und) may be
heard. This does not indicate a malfunction.
■ Active Cornering Assist operation sounds and vibrations
When the Active Cornering Assist is operated, operation sounds and vibra-
tions may be generated from the brake system, but this is not a malfunction.
■ Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally re-enabled in the following situations:
● When the engine switch is turned off
● If only the TRAC system is turned off, the TRAC will turn on wh en vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-e nabling will
not occur when vehicle speed increases.
■ Operating conditions of Active Cornering Assist
The system operates when the following occurs.
●TRAC/VSC can operate
● The driver is attempting to accelerate while turning
● The system detects that the vehicle is sliding to the outer sid e
● The brake pedal is released
■ Secondary Collision Brake operating conditions
The system operates when the SRS airbag sensor detects a collis ion while
the vehicle is in motion.

■Secondary Collision Brake automatic cancellation
The system is automatically canceled in any of the following si tuations.
● The vehicle speed drops below approximately 6 mph (10 km/h)
● A certain amount of time elapses during operation
● The accelerator pedal is depressed a large amount
■ Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the s ystem from
overheating when there is frequent steering input over an exten ded period of
time. The steering wheel may feel heavy as a result.
Should this occur, refrain from excessive steering input or sto p the vehicle
and turn the engine off. The EPS system should return to normal within 10
minutes.
