the front camera is outside of
the operational range, such as
when the vehicle is in the sun or
in an extremely cold environ-
ment
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 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 conditioning sys-
tem to increase the temperature 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
Unavailable” is displayedCheck whether there is attached materi-
als on the radar sensor and radar sensor
