If the camera lens becomes dirty, it
cannot transmit a clear image. If wa-
ter droplets, snow or mud adhere to
the lens, rinse with water and wipe

tremely dirty, wash it with a mild
cleanser and rinse.
NOTICE
The parking assist monitor may not
operate properly in the following
cases.
• If the back of the vehicle is hit, the
position and mounting angle of the
camera may change.
• As the camera has a water proof
construction, do not detach, disas-
semble or modify it. This may cause
incorrect operation.
• Do not strongly rub the camera lens.
If the camera lens is scratched, it
cannot transmit a clear image.
• Do not allow organic solvent, car
wax, window cleaner or glass coat
to adhere to the camera. If this hap-
pens, wipe it off as soon as possible.

such as when hot water is poured on
the vehicle in cold weather, the sys-
tem may not operate normally.
• When washing the vehicle, do not
apply intensive bursts of water to the
camera or camera area. Doing so
may result in the camera malfunc-
tioning.
Do not expose the camera to strong
impact as this could cause a malfunc-
tion. If this happens, have the vehicle
