WARNING
■Cautions regarding the use of the system
There  is  a  limit  to  the  degree  of  recognition  accuracy  and  cont rol  perfor-
mance that this system can provide, do not overly rely on this  system. The
driver is always responsible for paying attention to the vehicl e’ surroundings
and driving safely.
■ To ensure the system can operate properly
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 damage the sensors, and always keep them clean.
● Do not attach a sticker or install an electronic component, such as a backlit
license  plate  (especially  fluorescent  type),  fog  lights,  fender   pole  or  wire-
less antenna near a radar sensor.
● Do  not  subject  the  surrounding  area  of  the  sensor  to  a  strong  impact.  If
subjected to an impact, have the vehicle inspected by your Toyota dealer.
If the front or rear bumper needs to be removed/installed or replaced, con-
tact your Toyota dealer.
● Do not modify, disassemble or paint the sensors.
● Do not attach a license plate cover.
● Keep your tires properly inflated.
■ When to disable the function
In  the  following  situations,  disable  the  function  as  it  may  operate  even
though there is no possibility of a collision.
● Failing to observe the warnings above.
● A non-genuine Toyota suspension (lowered suspension, etc.) is installed.
■ 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.
● 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.
● When using an automatic car wash, disable the intuitive parking  assist

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

Situations in which the syst em may not operate properly
The  RCTA  function  may  not  detect  vehicles  correctly  in  the  foll owing  situa-
tions:
● When  the  sensor  is  misaligned  due  to  a  strong  impact  to  the  sensor  or  its

Parking Support Brake f
unction (static objects)
Ultrasonic sensors are used to  detect static objects, such as a wall,
in  the  detection  area  when  driving  at  a  low  speed  or  backing  up .
(  P. 368)
■Parking Support Brake function (rear-crossing vehicles)
Rear radar sensors are used to detect approaching vehicles in t he
detection area behind the v ehicle when backing up. (P. 372)
PKSB (Parking Suppor t Brake)
: If equipped
The  Parking  Support  Brake  system  consists  of  the  following
functions  that  operate  when  dr iving  at  a  low  speed  or  backing
up, such as when parking. When  the system determines that the
possibility of a collision with  a detected object is high, a wa rning
operates  to  urge  the  driver  to  take  evasive  action.  If  the  syst em
determines  that  the  possibility  of  a  collision  with  a  detected
object is extremely high, the br akes are automatically applied to
help  avoid  the  collision  or  help  reduce  the  impact  of  the  colli -
sion.
