The  RCTA  functions  when  your  vehicle  is  in  reverse.  It  can  detect
other vehicles approaching from the right or left rear of the v ehicle. It
uses radar  sensors  to alert  the  driver of the  other vehicle’s existence
through flashing the outside rear  view  mirror indicators and so unding
a buzzer.
■RCTA icon displa y (if equipped)
When a vehicle approaching from the right or left at the rear o f the
vehicle is detected, the following will be displayed on the aud io sys-
tem screen.

■Conditions under which the RCTA function may not function corre ctly
● The RCTA function may not detect vehicles correctly in the following condi-
tions:
• When the sensor is misaligned due to a strong impact to the se nsor or its
surrounding area
• When ice or mud, etc. is attached to the rear bumper
• During bad weather such as heavy rain, fog, snow, etc.
• When multiple vehicles approach continuously
• Shallow angle parking
• When a vehicle is approaching at high speed
• When parking on a steep incline, such as hills, a dip on the road, etc.
• Directly after the RCTA function is turned on
• Directly after the hybrid system is started with the RCTA func tion on.
• When items such as a bicycle carrier are installed on the rear  of the vehi-
cle
● Instances  of  the  RCTA  function  unnecessarily  detecting  a  vehicl e  and/or
object may increase in the following situations:
• When a vehicle passes by the side of your vehicle
• When  the  distance  between  your  vehicle  and  metal  objects,  such   as  a
guardrail, wall, sign, or parked vehicle, which may reflect electrical waves
toward the rear of the vehicle, is short
The  brightness  of  the  indicators  on  the  outside  rear  view  mirro rs and
the volume of the RCTA buzzer can be changed on   (4.2-inch dis-
play)  or    (7-inch  display)  ( P.  113,  129)  of  the  multi-information
display.
• Vehicles  that  the  sensors  cannot detect because of obstacles
• When  the  parking  space  faces  a street  and  vehicles  are  being  driven
on the street

: If equipped
The  distance  from  your  vehicle  to  nearby  objects  when  parallel
parking  or  maneuvering  into  a  garage  is  measured  by  the  sen-
sors  and  communicated  via  the  displays  and  a  buzzer.  Always
check the surrounding area wh en using this system.

■Sensor detection information
●The  sensor’s  detection  areas  are  limited  to  the  areas  around  th e  vehicle’s
bumper.
● Depending  on  the  shape  of  the  object  and  other  factors,  the  det ection  dis-
tance may shorten, or detection may be impossible.
● Objects may not be detected if they are too close to the sensor .
● There  will  be  a  short  delay  between  object  detection  and  displa y.  Even  at
slow  speeds,  there  is  a  possibility  that  the  object  will  come  w ithin  the  sen-
sor’s detection areas before the display is shown and the buzze r sounds.
● Thin  posts  or  objects  lower  than  the  sensor  may  not  be  detected   when
approached, even if they have been detected once.
● It  might  be  difficult  to  hear  beeps  due  to  the  volume  of  audio  system  or  air
flow noise of the air conditioning system.
■ If  “Parking  Assist  Unavailable  Please  Clean  Parking  Assist  Sens or”  is
displayed on the multi-information display
A  sensor  may  be  dirty  or  covered  with  snow  or  ice.  In  such  case s, if it is
removed from the sensor, the system should return to normal.
Also,  due  to  the sensor  being  frozen  at  low  temperatures,  a  mal function dis-
play  may  appear  or  an  object  may  not  be  detected.  If  the  sensor  thaws  out,
the system should return to normal.
■ If “Parking Assist Unavailable” is displayed on the multi-infor mation 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.
■ Certification

WARNING
■ When using the intuitive parking assist
Observe the following precautions.
Failing  to  do  so  may  result  in  the  vehicle  being  unable  to  be  d riven  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  t he  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  w ill  resolve
this problem.)
● The sensor is frozen. (Thawing the area will resolve this probl em.)
In  especially  cold  weather,  if  a  sensor  is  frozen  the  screen  ma y  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.
● On an extremely bumpy road, on an incline, on gravel, or on grass.
● The  vicinity  of  the  vehicle  is  noisy  due  to  vehicle  horns,  moto rcycle
engines, air brakes of large vehicles, or other loud noises pro ducing ultra-
sonic waves.
● There is another vehicle equipped with parking assist sensors i n 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 i nstalled.
● 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.
