THE CAMERA
The camera for the parking assist moni-
tor is located as shown in the illustration.
USING THE CAMERA
If the camera lens becomes dirty, it can-
not transmit a clear image. If water drop-
lets, snow or mud adhere to the lens,
rinse with water and wipe with a soft
cloth. If the lens is extremely dirty, wash
it with a mild cleanser and rinse.
NOTICE
●The parking assist monitor may not oper-
ate properly in the following cases.
• If the back of the vehicle is hit, the posi-
tion and mounting angle of the camera
may change.
• As the camera has a water proof con-
struction, do not detach, disassemble 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 a glass coating 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 malfunctioning.
●Do not expose the camera to strong
impact as this could cause a malfunction.
If this happens, have the vehicle
inspected by any authorized Lexus dealer
or repairer, or another duly qualified and
equipped professional as soon as possi-
ble.
