REAR VIEW MONITOR SYSTEM
203
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, shift to “R” when the “POWER”
switch is in ON mode.
If you move the shift position out of “R”, 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
Never 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.
Never 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.
Do not use the system when the
back door is not completely
closed.
Use 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.
Do not use the system in the follow-
ing cases:
On icy or slick road surfaces, or
in snow.
When using tire chains or emer-
gency tires.
On an uneven road, such as a
slope.

NOTICE
If 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
Toyota dealer.
As the camera has a water proof
construction, do not detach, disas-
semble or modify it. This may
cause incorrect operation.
If the temperature changes rapidly,
such as when hot water is poured
on the vehicle in cold weather, the
system may not operate normally.
Do 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.
When replacing the tires, please
consult your Toyota dealer. If you
replace the tires, the area dis-
played on the screen may change.
When 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.
Area displayed on screen
Image is displayed approximately level
on screen.

If there is a problem, stop the ve-
hicle and disable the system by
touching on the screen.
Be sure to check that the vehicle
can actually park in the target
space before beginning operation.
Do not use the system in the follow-
ing conditions:
Outside of parking areas
In unprepared parking area such
as gravel or sand
In parking areas that are crooked
or have level variations
On slippery or icy roads, or in
snow
If the asphalt is melted due to
harsh sunlight
If there are obstacles in the tar-
get parking position (inside the
green frame), or obstacles be-
tween the vehicle and the park-
ing space
If there are a large number of ve-
hicles or pedestrians passing
In areas unsuitable for parking
(overly small parking space, cliff
etc.)
If the image is hard to see due to
dirt, direct sunlight, shadow or
snow on the camera lens
If you are using tire chains or
emergency tire(s)
Do not use tires other than those
installed by the manufacturer, as
the system may not function cor-
rectly. Furthermore, if you change
the tires, there may be errors in the
positions of the lines and frames
displayed on the screen. If you
wish to change your t ires, see your
Toyota dealer .
In the following conditions, as-
sisted parking in the set parking
position may not be possible:
The tires are extremely worn, or
the tire inflation pressure is low
You are carrying an extremely
heavy load
There is a load in one side of the
vehicle only, causing the vehicle
to lean
Tires have received a strong im-
pact, such as bumping against a
curb, resulting in improper
wheel alignment
Do not use the system when the
back door is not completely
closed.
If 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
Toyota dealer.
As the camera has a water proof
construction, do not detach, disas-
semble or modify it. This may
cause incorrect operation.
If 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.
If you scrape the camera cover, or
scrub it with a hard brush or an
abrasive agent, you may scratch
the cover, leading to poor picture
quality.
