REAR VIEW MONITOR SYSTEM
290
The rear view monitor system assists
the driver by displaying an image of the
view behind the vehicle while backing
up. 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.
To display the rear view image on the
screen, shift the shift position to “R”
when the “POWER” switch is in ON
mode.
If you move the shift position out of the “R”,
the screen returns to the previous screen.
Operating another function of the naviga-
tion system will display another screen.
Vehicles with intuitive parking assist−
sensor — when the intuitive parking as-
sist− sensors are turned on and an ob-
stacle is detected in front of or behind
your vehicle, a warning appears on the
right top of the rear view monitor. For
details, see “Intuitive parking assist” on
page 304.
The rear view monitor system is a supple-
ment device intended to assist back up.
When backing up, be sure to check behind
and all around the vehicle visually.CAUTION
DNever depend on the rear view
monitor system entirely when
backing up. Always make sure
your intended path is clear.
Use caution, just as you would
when backing up any vehicle.
DNever back up while looking only at
the screen. The image on the
screen is different from actual
conditions. Depicted distances
between objects and flat surfaces
will differ from actual distance. If
you back up while looking only at
the screen, you may hit a vehicle, a
person or an object. When backing
up, be sure to check behind and all
around the vehicle visually and
with mirrors before proceeding.
DDo not use the system when the
trunk is not completely closed.
DUse your own eyes to confirm the
vehicle’s surroundings, as the dis-
played 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 ve-
hicle visually and with mirror be-
fore proceeding.
DDo not use the system in the follow-
ing cases:
DOn icy or slick road surfaces, or
in snow.
DWhen using tire chains or emer-
gency tires.
DOn an uneven or indirect road,
such as a slope or curve.

NOTICE
DIf the back of the vehicle is hit, the
position and mounting angle of the
camera may change. Be sure to
have the camera’s position and
mounting angle checked at your
Lexus dealer.
DAs the camera has a water proof
construction, do not detach, disas-
semble or modify it. This may
cause incorrect operation.
DIf the temperature changes rapidly,
such as when hot water is poured
on the vehicle in cold weather, the
system may not operate normally.
DDo not strongly rub the camera
lens. If the camera lens is
scratched, it can not transmit a
clear image.
DDo 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.
DIf the tire size is changed, the area
displayed on the screen may
change.
DWhen washing the vehicle, do not
apply intensive bursts of water to
the camera or camera area. Doing
so may result in the camera mal-
functioning.
INFORMATION
If the camera lens becomes dirty, it
cannot transmit a clear image. If wa-
ter droplets, snow, or mud adhere to
the lens, rinse with water and wipe
with a soft cloth. If the lens is ex-
tremely dirty, wash it with a mild
cleanser and rinse.
