To clean the part of the windshield in front of
the front camera, use the windshield wipers
or the windshield defogger of the air condi-
tioning system (P.348).
If the front camera is hot, such as after the
vehicle had been parked in the sun, use the
air conditioning system to decrease the tem-
perature 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 cam-
era to become excessively high.
If the front camera is cold, such after the
vehicle is parked in an extremely cold envi-
ronment, use the air conditioning system to
increase the temperature around the front
camera.
Close the hood, remove the sticker, etc. to
clear the obstruction.
