■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
