covered  with  dirt,  moisture  (fogged
up,  covered  with  condensation,  ice,
etc.), or other foreign matterUsing  the  wiper  and  A/C  function,

When  the  temperature  around  the
front camera is outside of the opera-
tional range, such as when the vehi-
cle  is  in  the  sun  or  in  an  extremely
cold environment
If  the  front  camera  is  hot,  such  as
after the vehicle had been parked in
the sun, use the air conditioning sys-
tem  to  decrease  the  temperature
around the front camera.
If  a  sunshade  was  used  when  the
vehicle  was  parked,  depending  on
its  type,  the  sunlight  reflected  from
the  surface  of  the  sunshade  may
cause  the  temperature  of  the  front
camera to become excessively high.
If the front camera is cold, such after
the vehicle is parked in an extremely
cold  environment,  use  the  air  condi-
tioning  system  to  increase  the  tem-
perature around the front camera.
The area in front of the front camera
is  obstructed,  such  as  when  the
hood is open or a sticker is attached
to  the  part  of  the  windshield  in  front
of the front camera. Close  the  hood,  remove  the  sticker,
etc. to clear the obstruction.
When  “Pre-Collision  System  Radar
In  Self  Calibration  Unavailable  See

materials  on  the  radar  sensor  and
radar  sensor  cover,  and  if  there  is,
