●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

●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.

WARNING
■Limitations of the Intelligent Clearance Sonar system
Do not overly rely on the system, as doing so may lead to an accident.
● 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  vehicle,  it  is
necessary to depress the brake pedal immediately as brake control will be
canceled after approximately 2 seconds.
■ To ensure the Intelligent Clearance Sonar system can operate pr operly
Observe the following precautions regarding the sensors ( P. 324). Failure
to  do  so  may  cause  a  sensor  to  not  operate  properly,  and  may  cause  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 impact.
● 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.
● Do not modify, disassemble or paint the sensors.
● Do not replace a radar sensor with a part other than a genuine part.
● Do not subject a radar sensor or its surrounding area to a strong impact.
● Do not damage the radar sensors, and always keep the radar sensors and
their surrounding area on the bumper clean.
■ Handling the suspension
Do not modify the suspension, as changes to the height or inclination of the
vehicle  may  prevent  the  sensors  from  detecting  objects  correctly  or  cause
the system to not operate or operate unnecessarily.

NOTICE
■To prevent the system from malfunctioning
● If the area around a sensor is subjected to an impact, the system may not
operate  properly  due  to  the  sensor  being  misaligned.  Have  the  vehicle
inspected by your Toyota dealer.
● When using a high pressure washer to wash the vehicle, do not spray the
sensors directly, as doing so may cause a sensor to malfunction .
● When  using  steam  to  clean  the  vehicle,  do  not  direct  steam  too  close  to
the sensors as doing so may cause a sensor to malfunction.
■ To prevent a radar sensor from malfunctioning
● If  the  area  around  a  radar  sensor  is  subjected  to  an  impact,  the  system
may  not  operate  properly  due  to  a  sensor  malfunction.  Have  the  vehicle
inspected by your Toyota dealer.
● Observe the radar sensor handling precautions. ( P. 300)
■ To  prevent  unnecessary  operation  of  the  Intelligent  Clearance  S onar
system
In  the  following  situations,  disable  the  Intelligent  Clearance  Sonar  system
as the system may operate even though there is no possibility of a collision.
● When inspecting the vehicle using a chassis roller, chassis dynamo or free
roller
● When loading the vehicle onto a boat, truck or other transport  vessel
● If the suspension has been modified or tires of a size other than specified
are installed
● If the front of the vehicle is raised or lowered due to the carried load
● When equipment that may obstruct a sensor is installed, such as a towing
eyelet,  bumper  protector  (an  additional  trim  strip,  etc.),  bicycle  carrier,  or
snow plow
● When using an automatic car wash

• 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
• Hybrid system 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:
● Hybrid system 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. 306).
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
