Use your own eyes to confirm the
vehicle’s surroundings, as the
displayed image may become faint
or dark, and moving images will be
distorted, or not entirely visible
when the outside temperature is

If the back of the vehicle is hit, the
position and mounting angle of the
camera may change. Be sure to
have the camera’s position and
mounting angle checked at your

As the camera has a water proof
construction, do not detach, disas-
semble or modify it. This may
cause incorrect operation.
If the temperature changes rapidly,
such as when hot water is poured
on the vehicle in cold weather, the
system may not operate normally.
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 pos-

When replacing the tires, please
consult your Toyota dealer. If you
replace the tires, the area dis-
played on the screen may change.
When washing the vehicle, do not
