■If “Parking Assist Unavailable” is displayed on the multi-information dis-
play
●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.
●Initialization may not have been performed after a battery terminal was dis-
connected and reconnected. Initialize the system. If this message continues
to  be  displayed  even  after  initialization,  have  the  vehicle  inspected  by  your
Toyota dealer.
■Certification
For vehicles sold in Canada
This ISM device complies with Canadian ICES-001.
Cet appareil ISM est conforme a la norme NMB-001 du Canada.
■Customization
Some functions can be customized. (P. 100, 506)
WARNING
■When using the intuitive parking assist
Observe the following precautions.
Failing  to  do  so  may  result  in  the  vehicle  being  unable  to  be  driven  safely
and possibly cause an accident.
●Do not use the sensor at speeds in excess of 6 mph (10 km/h).
●The sensors’ detection areas and reaction times are limited. When moving
forward  or  reversing,  check  the  areas  surrounding  the  vehicle  (especially
the  sides  of  the  vehicle)  for  safety,  and  drive  slowly,  using  the  brake  to
control the vehicle’s speed.
●Do not install accessories within the sensors’ detection areas.

WARNING
■Sensors
Certain  vehicle  conditions  and  the  surrounding  environment may affect  the
ability  of  a  sensor  to  correctly  detect  an  object.  Particular  instances  where
this may occur are listed below.
●There  is  dirt,  snow  or  ice  on  the  sensor.  (Wiping  the  sensors  will  resolve
this problem.)
●The sensor is frozen. (Thawing the area will resolve this problem.)
In  especially  cold  weather,  if  a  sensor  is  frozen  the  screen  may  show  an
abnormal display, or objects may not be detected.
●The sensor is covered in any way.
●The vehicle is leaning considerably to one side.

●The  vicinity  of  the  vehicle  is  noisy  due  to  vehicle  horns,  motorcycle
engines, air brakes of large vehicles, or other loud noises producing ultra-
sonic waves.
●There is another vehicle equipped with parking assist sensors in the vicin-
ity.
●The sensor is coated with a sheet of spray or heavy rain.
●The sensor is drenched with water on a flooded road.
●The vehicle is equipped with a fender pole or wireless antenna.
●Towing eyelets are installed.
●The bumper or sensor receives a strong impact.
●The vehicle is approaching a tall or curved curb.
●The detection range is reduced due to an object such as a sign.
●In harsh sunlight or intense cold weather.
●The area directly under the bumpers is not detected.
●If objects draw too close to the sensor.
●A non-genuine Toyota suspension (lowered suspension, etc.) is installed.
●A backlit license plate is installed.
In addition to the examples above, there are instances in which, because of
their shape, signs and other objects may be judged by a sensor to be closer
than they are.

WARNING
■Objects which may not be properly detected
The shape of the object may prevent a sensor from detecting it. Pay partic-
ular attention to the following objects:
●Wires, fences, ropes, etc.

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 Toyota dealer.
●The intuitive parking assist operation display flashes, and a buzzer sounds
when no objects 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 area.
Doing so may result in the sensor malfunctioning.

2844-5. Using the driving support systems
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  may  occur  due  to  the  vehicle  sud-
denly  moving  forward  due  to  an  accidental  accelerator  pedal
operation,  the  vehicle  moving  the  unintended  direction  due  to
the wrong shift position being selected, or while parking or trav-
eling  at  low  speeds,  the  sensors  detect  objects,  such  as  a  wall,
in the traveling direction of the vehicle, and the system operates
to lessen an impact with an object and reduce the resulting dam-
age.

2864-5. Using the driving support systems
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 function will per-
form  brake  control  to  reduce  the  likelihood  of  an  impact  with  the
approaching vehicle.
■Examples of system operation
The  system  will  operate  in  situations  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

If  the  engine  output  restriction  control  or  brake  control  operates,  a
buzzer will sound and a message will be displayed on the multi-infor-
mation display to alert the driver.
Depending on the situation, engine output restriction control will operate to
either limit acceleration or restrict output as much as possible.

If the Intelligent Clearance Sonar function detects that a collision with
an  object  is  possible,  the  engine  output  will  be  restricted  to restrain
any  increase  in  the  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.)
