● Bicycles or similar objects may not be detected.
● In  the  situations  shown  below,  the  system  may  not  be  able  to  accurately
detect  surrounding  brightness  levels.  This  may  cause  the  low  be ams  to
remain  on  or  the  high  beams  to  cause  problems  for  pedestrians,  vehicles
ahead  or  other  parties.  In  these  cases,  manually  switch  between   the  high

■The windshield wiper and washer can be operated when
Vehicles without a smart key system
The engine switch is in the “ON” position.
Vehicles with a smart key system
The engine switch is in IGNITION ON mode.
■ Effects  of  vehicle  speed  on  wip er  operation  (vehicles  with  rain-sensing
windshield wipers)
Even  when  the  wipers  are  not  in  “AUTO”  mode,  wiper  operation  va ries
depending on vehicle speed when the washer is being used (delay  until drip
prevention wiper sweep occurs).
■ Raindrop sensor (vehicles with rain-sensing windshield wipers)
●If the wiper switch is turned to the “AUTO” position while the  engine switch is
in  IGNITION  ON  mode,  the  wiper  will  operate  once  to  show  that  “ AUTO”
mode is activated.
● If  the  temperature  of  the  raindrop  sensor  is  194 F  (90 C)  or  higher,  or  5 F
(-15 C)  or  lower,  automatic  operation  may  not  occur.  In  this  case,  o perate
the wipers in any mode other than “AUTO”.
■ If no windshield washer fluid sprays
Check that the washer nozzles  are not  blocked if there is  washe r  fluid in the
windshield washer fluid reservoir. ● The  raindrop  sensor  judges  the  amount
of raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from the
rising or setting of the sun intermittently
strikes  the  windshield,  or  if  bugs,  etc.,
are present on the windshield.

WARNING
■Caution regarding the use of washer fluid
When  it  is  cold,  do  not  use  the  washer  fluid  until  the  windshie ld  becomes
warm. The  fluid may freeze  on  the  windshield and cause low visi bility. This
may lead to an accident, resulting in death or serious injury.
■ Caution regarding the use of wind shield wipers in “AUTO” mode (vehi-
cles with rain-sensing windshield wipers)
The windshield wipers may operate unexpectedly if the sensor is  touched or
the  windshield  is  subject  to  vibration  in  “AUTO”  mode. Take  car e  that  your
fingers, etc., do not become caught in the windshield wipers.
NOTICE
■ When the windshield is dry
Do not use the wipers, as they may damage the windshield.
■ When there is no washer flu id spray from the nozzle
Damage  to  the  washer  fluid  pump  may  be  caused  if  the  lever  is  p ulled
toward you and held continually.
■ When a nozzle becomes blocked
In this case, contact your Toyota dealer.
Do not try to clear it with a pin or other object. The nozzle w ill be damaged.

2184-5. Using the driving support systems
C-HR_OM_USA_OM10569U
The  pre-collision  system  is  equipped  with  a  sophisticated  compu ter
that will record certain data, such as: • Accelerator status
• Brake status
• Vehicle speed
• Operation status of the pre-collision system functions
• Information (such as the dist ance and relative speed between y our
vehicle and the vehicle  ahead or other objects)
• Images  from the camera  sensor (available  only  when  the  pre-col li-
sion  braking  function  or  the  pre-collision  brake  assist  functio n  was
operating)
The  pre-collision  system  does  no t  record  conversations  sounds  or
images of the inside of the vehicle.
● Data usage
Toyota  may  use  the  data  recorded  in  this  computer  to  diagnose
malfunctions,  conduct  research  and  development,  and  improve
quality.
Toyota will not disclose the recorded data to a third party exc ept:
• With the consent of the vehicle owner or with the consent of t he
lessee if the vehicle is leased
• In response to an official request by the police, a court of l aw or a
government agency
• For use by Toyota in a lawsuit
• For  research  purposes  where  the  data  is  not  tied  to  a  specific vehicle or vehicle owner
● Recorded images can be erased  using a specialized device.
The image recording function can be disabled. However, if the f unc-
tion  is  disabled,  data  from  when  the  pre-collision  system  opera tes
will not be available.
