WARNING
■Obstacles which may not  be properly detected
The shape of the obstacle may prevent a sensor from detecting i t. Pay par-
ticular attention to the following obstacles:
● Wires, fences, ropes, etc.
● Cotton, snow and other materials that absorb sound waves
● Sharply-angled objects
● Low obstacles
● Tall  obstacles  with  upper  sections  projecting  outwards  in  the  d irection  of
your vehicle
● People may not be detected if they are wearing certain types of  clothing.
● Moving objects such as people or animals
NOTICE
■When using intuitive parking assist
In  the  following  situations,  the  system  may  not  function  correctly  due  to  a
sensor malfunction, etc. Have the vehicle checked by your Toyot a dealer.
● The intuitive parking assist operation display flashes, and a b uzzer sounds
when no obstacles are detected.
● If  the  area  around  a  sensor  collides  with  something,  or  is  subjected  to
strong impact.
● If the bumper collides with something.
● If the display shows continuously without beeping, except when the buzzer
volume is muted.
● If a display error occurs, first check the sensor.
If the error occurs even if there is no ice, snow or mud on the  sensor, it is
likely that the sensor is malfunctioning.
■ Notes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor a rea.
Doing so may result in the sensor malfunctioning.

Driving
The system will operate in situations such as the following if an object
is detected in the traveling  direction of the vehicle.
◆When  traveling  at  a  low  speed  and  the  brake  pedal  is  not
depressed, or is depressed late
Intelligent Clearance Sonar (ICS)
: If equipped
If  a  collision  with  an  object  ma y  occur  due  to  the  vehicle  sud-
denly  moving  forward  due  to  an   accidental  accelerator  pedal
operation,  the  vehicle  moving  th e  unintended  direction  due  to
the wrong shift position being se lected, or while parking or trav-
eling  at  low  speeds,  the  sensors  detect  objects,  such  as  a  wall ,
in the traveling direction of t he vehicle, and the system opera tes
to lessen an impact with an object and reduce the resulting dam -
age.

Driving
If a radar sensor detects a vehicle approaching from the right or left at
the rear of the vehicle and a collision may occur, this functio n will per-
form  brake  control  to  reduce  th e  likelihood  of  an  impact  with  the
approaching vehicle.
■Examples of system operation
The  system  will  operate  in  situat ions  such  as  the  following  if an
object is detected in the traveling direction of the vehicle.
◆When reversing, a vehicle is approaching and the brake pedal
is not depressed, or is depressed late

■Re-enabling the Intellig ent 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. 322), or turn the power switch off and then back to 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 d etect
The sensors may not be able to detect certain objects, such as the following.
● Cotton cloth, snow, and other materials that are poor reflector s of ultrasonic
waves. 
(People may also not be detected depending on the type of cloth ing they are
wearing.)
● Objects which are not perpendicular to the ground, are not perp endicular to
the traveling direction of the vehicle, are uneven or are wavin g.
● Low objects
● Thin objects such as wires, fences, ropes and signposts
● Objects that are extremely close to the bumper
■ Intuitive parking assist buzzer
Regardless  of  whether  the  intuitive  parking  assist  system  is  en abled  or  not
( P. 311), if the Intelligent Clearance Sonar system is enabled ( P. 322), the
front or rear sensors detect an object and brake control is performed, the intu-
itive  parking  assist  buzzer  will  sound  to  notify  the  driver  of  the  approximate
distance to the object.

■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

●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 
Page 330 of 592
3304-5. 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 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
● A  sensor  may  be  covered  with  ice,  snow,  dirt,  etc.  Remove  the  ice,  snow,
dirt, etc., from the sensor to return the system to normal.
Also,  due  to  ice  forming  on  a  sensor  at  low  temperatures,  a  war ning  mes-
sage  may  be  displayed  or the  sensor may  not  be able  to  detect  an  object.
Once the ice melts, the system will return to normal.
● If this message continues to be displayed even after cleaning the sensor, or
is displayed even though the sensor is clean, have the vehicle  inspected by
your Toyota dealer.
● Initialization  may  not  have  been  performed  after  a  12-volt  batt ery  terminal
was disconnected and reconnected. Initialize the system. (P. 330)

WARNING
■Limitations of the Intelligent Clearance Sonar system
Do not overly rely on the system, as doing so may lead to an ac cident.
● 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  ve hicle,  it  is
necessary to depress the brake pedal immediately as brake contr ol will be
canceled after approximately 2 seconds.
■ To ensure the Intelligent Clearan ce Sonar system can operate properly
Observe the following precautions regarding the sensors ( P. 322). Failure
to  do  so  may  cause  a  sensor  to  not  operate  properly,  and  may  ca use  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 imp act.
● 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 stro ng impact.
● Do not damage the radar sensors, and always keep the radar sens ors and
their surrounding area on the bumper clean.
