2-4. Using other driving systems
CAUTION
■When using the rear view monitor system, observe these precautions to avoid an
accident that could result in death or serious injuries.
●Never depend solely on the monitor system when reversing.
●Always check visually and with the mirrors to confirm your intended path is clear.
●Depicted distances between objects and flat surfaces differ from actual dis-
tances.
●Do not use the system if the trunk is open.
■Conditions which may affect the rear view monitor system
●If the back of the vehicle is hit, the camera's position and mounting angle may
change. Contact your Lexus dealer.
●Rapid temperature changes, such as when hot water is poured on the vehicle in
cold weather, may cause the system to function abnormally.
●If the camera lens is dirty, it cannot transmit a clear image. Rinse with water and
wipe with a soft cloth. If extremely dirty, wash with a mild cleanser and rinse.
●The displayed image may be darker and mo ving images may be slightly distorted
when the system is cold.
