Rear view monitor system
■Displayed area
The rear view monitor system assists the driver by displaying an image of the
area behind the vehicle. The displayed image is a horizontally reversed mirror
image of the inside rear view mirror.
Rear view image is displayed when
the selector lever is in the “R” posi -
tion.
If you move the lever out of “R”
position, the screen returns to the
previous one.
The area covered by the camera is limited.
Objects which are close to either corner
of the bumper or under the bumper can-
not be seen on the screen.
The area displayed on the screen may vary
according to vehicle orientation or road
conditions.

■Rear view monitor system camera
■Smear effect
In the following cases, it may become difficult
to see the images on the screen, even when
the system is functioning correctly.
• In the dark (e.g., at night).
• If the temperature near the lens is extremely high or low.
• If water droplets adhere to the camera, or when humidity is high (e.g., when it rains).
• If foreign matter (e.g., snow or mud) adheres to the camera lens.
• If the sun or headlights are shining directly
into the camera lens.
If a bright light (for example, sunlight
reflected off the vehicle body) is picked up by
the camera, a smear effect* peculiar to the
camera may occur.
*: Smear effect-A phenomenon that occurs when a bright light (for example, sunlight
reflected off the vehicle body) is picked up
by the camera; when transmitted by the
camera, the light source appears to have a
vertical streak above and below it.

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. See 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.
