REAR VIEW MONITOR SYSTEM
284
The rear view monitor system assists
the driver by displaying an image of the
view behind the vehicle while backing
up.
To display the rear view image on the
screen, shift the shift lever to the “R”
position when the “ENGINE START
STOP” switch is in IGNITION ON mode.
If you move the shift lever out of the “R”, the
screen returns to the previous screen. Op-
erating another function of the navigation
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 290.
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 road, such as a
slope.

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 cannot transmit a
clear image.
DDo not allow organic solvent, car
wax, window cleaner or glass coat
to adhere to the camera. If this hap-
pens, wipe it off as soon as pos-
sible.
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.
DArea displayed on screen
Image is displayed approximately level
on screen.
Corners of bumper
The area detected by the camera is limi-
ted. The camera does not detect objects
which are close to either corner of the
bumper or under the bumper.

era
The rear view monitor system camera is lo-
cated on the trunk as shown in the illustra-
tion.

In the following cases, it may become diffi-
cult to see the images on the screen, even
when the system is functioning.
DIn the dark (for example, at night)
DWhen the temperature near the lens is
high or low
DWhen water droplets are adhering to
the camera, or when humidity is high
(for example, when it rains)
DWhen foreign matter (for example,
snow or mud) is adhering to the camera
DWhen the camera has scratches or dirt
on it
DWhen the sun or the beam of head-
lights is shining directly into the camera
