see images on the screen even when the sys-
tem is functioning correctly:
●The vehicle is in a dark area, such as at
night.
●The temperature near the lens is extremely
high or low.
●Water droplets are on the camera lens or
humidity is high, such as when it rains.
●Foreign matter, such as snow and mud,
adheres to the camera lens.
●When the camera has scratches or dirt on
it.
●The sun or headlights are shining directly
into the camera lens.
If a bright light, such as sunlight reflected off
the vehicle body, is picked up by the camera,
a smear effect* characteristic to the camera
may occur.

occurs when a bright light is picked up by
the camera; when transmitted by the cam-
era, the light source appears to have a ver-
tical streak above and below it.
