could cause the outer surface of the
windshield to fog up blocking your vi-
sion.

AIR CONDITIONING

The air conditioning filter is behind the
glove box.
The air conditioning filter may clog after
long use. The filter may need to be re-
placed if the air flow of the air conditioner
and heater experiences extreme reduc-
tions in operating efficiency, or if the win-
dows become to fog up easily.
To maintain the air conditioning efficiency,
inspect and replace the air conditioning fil-
ter according to the maintenance sched-
ule. In dusty areas or areas with heavy
traffic flow, such as inner city or desert
areas, early replacement may be required.

REAR VIEW MONITOR SYSTEM
286
The rear view monitor system assists
the driver by displaying an image of the
view behind the vehicle while backing
up. The left and right displayed on the
screen are the same as those of the in-
side rear view mirror.
To display the rear view image on the
screen, place the selector lever in the
“R” position when the ignition switch is
in the “ON” position.
If you move the selector lever out of the “R”
position, the screen returns to the previous
screen. Operating another function of the
navigation system will display another
screen.
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
backdoor is not completely closed.
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.

If the camera lens becomes dirty, it
cannot transmit a clear image. If
water droplets, snow, or mud ad-
here 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.
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.
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.
When replacing the tires, please con-
sult your Lexus dealer. If you replace
the tires, the area displayed on the
screen may change.
