Rear view monitor system (rear view mirror-attached type)∗
The rear view monitor system assists the driver by displaying an image of
the view behind the vehicle while reversing. The image is displayed in
reverse on the screen. This allows the image to appear in the same manner
as that of the rear view mirror.
The rear view image is displayed
when the shift lever is in the R
position.
The screen turns off in the fol-
lowing situations:
• The shift lever is shifted out
of R.
• The screen remains on for
approximately 5 minutes.
∗: If equipped

■Displayed area
■Driving precautionsThe area detected by the camera is limited.

the bumper or under the bumper cannot
be seen on the screen.
The area displayed on the screen may vary
according to vehicle orientation or road
conditions.
The camera uses a special lens.

When the grade behind the vehicle slopes
down sharply, objects appear to be closer
than they actually are.
The distance that appears on the screen
between three-dimensional objects (such
as vehicles) and flat surfaces (such as the
road) and the actual distance differ as fol-
lows.
In reality, C = A < B (C and A are equally far
away; B is farther than C and A). However,
on the screen, the situation appears to be A
< B < C.
On the screen, it appears that a truck is
parking about 0.5 m (1.5 ft.) away. How-
ever, in reality if you back up to point A, you
will hit the track.

■Rear view monitor system camera
■Smear effectThe rear view monitor system camera is
located on the back door as shown in the
illustration.
In the following cases, it may become difficult
to see the images on the screen, even when
the system is functioning correctly.
●The vehicle is in a dark area, such as at
night.
●The temperature near the lens is
extremely high or low.
●Water droplets are on the camera lens
or humidity is high, such as when it
rains.
●Foreign matter, such as snow or mud,
adheres to the camera lens.
●The sun or headlights are shining
directly into the camera lens.
●A bright object such as a white wall is
reflected in the mirror surface over the
monitor.
●The camera has scratches or dirt on it.
If a bright light, such as sunlight reflected
off the vehicle body, is picked up by the
camera, a smear effect* characteristic to
the camera may occur.
*: Smear effect  A phenomenon that
occurs when a bright light is picked up by
the camera; when transmitted by the
camera, the light source appears to have
a vertical streak above and below it.

■Flicker effect
When the camera is used under fluorescent light, sodium lights, or mercury lights
etc., the lights and the illuminated areas may appear to flicker.
CAUTION
■When using the rear view monitor system, observe the following 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.
●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 low. When backing up, be sure to check
behind and all around the vehicle visually and with the mirrors before proceeding.
●Always check the vehicle surrounding area, because the guide lines are ancillary
lines.
●The guide lines are ancillary lines and do not change even if the steering wheel is
turned.
●Depicted distances between objects and flat surfaces differ from actual dis-
tances.
●Do not use the system if the back door is open.

●If the back of the vehicle has been hit, the camera’s position and mounting angle
may have changed. Have the vehicle inspected by any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional.
●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 moving images may be slightly distorted
when the system is cold.
■Camera precautions
●As the camera has a water proof construction, do not detach, disassemble or
modify it. This may cause incorrect operation.
●Do not subject the camera to a strong impact.
●If the camera lens becomes dirty, it cannot 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. Do not rub hard.
●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.
●Do not strongly rub the camera lens. If the camera lens is scratched, it cannot
transmit a clear image.
●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.
