PCS (Pre-Collision System)
The  pre-collision  system  uses  a  radar  sensor  and  camera  sen-
sor  to  detect  vehicles  and  pedest rians  in  front  of  your  vehicle.
When the system determines that t he possibility of a frontal col-
lision with a vehicle or pedest rian is high, a warning operates  to
urge  the  driver  to  take  evasive  action  and  the  potential  brake
pressure is increased to help the driver avoid the collision. If the
system determines that the possi bility of a frontal collision with
a  vehicle  or  pedestrian  is  extremely  high,  the  brakes  are  auto-
matically  applied  to  help  avoid  the  collision  or  help  reduce  th e
impact of the collision.
The  pre-collision  system  can  b e  disabled/enabled  and  the  warnin g
timing can be changed. ( P.   2 2 8 )

mometer  or  speedometer  tester,  or  when  using  an  on  vehicle  whee l  bal-
ancer

In some situations such as the following, sufficient braking fo rce may not be
obtained, preventing the system from performing properly:
• If  the  braking  functions  cannot  operate  to  their  full  extent,  such  as  when
the brake parts are extremely cold, extremely hot, or wet
• If  the  vehicle  is  not  properly  maintained  (brakes  or  tires  are   excessively
worn, improper tire inflation pressure, etc.)
• When  the  vehicle  is  being  driven  on  a  gravel  road  or  other  sli ppery  sur-
face
● Some  pedestrians  such  as  the  following  may  not  be  detected  by  t he  radar
sensor and camera sensor, preventing the system from operating  properly:
• Pedestrians shorter than approximately 3.2 ft. (1 m) or taller t han approx-
imately 6.5 ft. (2 m)
• Pedestrians wearing oversized clothing (a rain coat, long skir t, etc.), mak-
ing their silhouette obscure

If the PCS warning light flashes or illuminates, and a warning  message is
displayed on the multi-information display
The  pre-collision  system  may  be  temporarily  unavailable  or  ther e  may  be  a
malfunction in the system.
● In  the  following  situations,  the  warning  light  will  turn  off,  t he  message  will
disappear  and  the  system  will  become  operational  when  normal  op erating
conditions return:
• When the radar sensor or camera sensor or the area around eith er sen-
sor is hot, such as in the sun
• When the radar sensor or camera sensor or the area around eith er sen-
sor is cold, such as in an extremely cold environment
• When a front sensor is dirty or covered with snow, etc.
• When  the  part  of  the  windshield  in  front  of  the  camera  sensor  is  fogged
up or covered with condensation or ice 
(Defogging the windshield:  P. 295)
• If  the  camera  sensor  is  obstructed,  such  as  when  the  hood  is  open  or  a sticker is attached to the windshield near the camera sensor
● If  the  PCS  warning  light  continues  to  flash  or  remains  illumina ted  or  the
warning message does not disappear even though the vehicle has  returned
to normal, the system may be malfunctioning. Have the vehicle inspected by
your Toyota dealer immediately.
■ If VSC is disabled
●If VSC is disabled ( P. 281), the pre-collision brake assist and pre-collision
braking functions are also disabled.
● The PCS warning light will turn on and “VSC Turned Off Pre-Coll ision Brake
System Unavailable.” will be displayed on the multi-information  display.

LDA (Lane Depar ture Al ert with steering 
control)
When driving on highways and freeways with white (yellow) lines , this
function  alerts  the  driver  when  the  vehicle  might  depart  from  i ts  lane
and  provides  assistance  by  opera ting  the  steering  wheel  to  keep the
vehicle in its lane.
The  LDA  system  recognizes  visi-
ble  white  (yellow)  lines  with  the
camera  sensor  on  the  upper  por-
tion of the windshield.
◆Lane departure alert function
When  the  system  determines
that  the  vehicle  might  depart
from  its  lane,  a  warning  is  dis-
played  on  the  multi-information
display  and  the  warning  buzzer
sounds to alert the driver.
When  the  warning  buzzer
sounds,  check  the  surrounding
road  situation  and  carefully
operate  the  steering  wheel  to
move  the  vehicle  back  to  the
center of the line.
