NOTICE
How to use the camera
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, disassem-
ble 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 happens, wipe it off as soon as possible.
• If the temperature changes rapidly, such as when hot water is poured on
the vehicle in cold weather, the system 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 malfunction-
ing.
• When the camera is used under fluorescent lights, sodium light or mer-
cury light etc., the lights and the illuminated areas may appear to
flicker.
Do not expose the camera to strong impact as this could cause a malfunc-
tion. If this happens, have the vehicle inspected by any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional as
soon as possible.
