REAR VIEW MONITOR SYSTEM
244
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 engine 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
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 distances. 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.
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,
disassemble 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
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 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.
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 mirror
before proceeding.

When replacing the tires, please con-
sult your Toyota dealer. If you replace
the tires, the area displayed on the
screen may change.
AREA DISPLAYED ON SCREEN
Image is displayed approximately level
on screen.

Corners of bumper On screen
The area detected by the camera is
limited. The camera does not detect
objects which are close to either
corner of the bumper or under the
bumper.
The area displayed on the screen
may vary according to vehicle orien-
tation or road conditions.

THE REAR VIEW MONITOR SYSTEM
CAMERA
The rear view monitor system camera is lo-
cated on the back door as shown in the il-
lustration. The camera uses a special lens.
The distance of the image that appears on
the screen differs from the actual distance.
In the following cases, it may become diffi-
cult to see the images on the screen, even
when the system is functioning.
In the dark (for example, at night)
When the temperature near the lens is
high or low
When water droplets are adhering to
the camera, or when humidity is high
(for example, when it rains)
When foreign matter (for example,
snow or mud) is adhering to the camera
When the sun or the beam of head-
lights is shining directly into the camera
lens

If a bright light (for example, sunlight re-
flected off the vehicle body) is picked up by
the camera, the smear effect
∗ peculiar to
the camera may occur.
∗: Smear effect—A phenomenon that oc-
curs when a bright light (for example, sun-
light reflected off the vehicle body) is
picked up by the camera; when trans-
mitted by the camera, the light source ap-
pears to have a vertical streak above and
below it.

This navigation system calculates the
current vehicle position using satellite
signals, various vehicle signals, map
data, etc. However, the accurate posi-
tion may not be shown depending on
the satellite condition, road configura-
tion, vehicle condition or other circum-
stances.
The Global Positioning System (GPS) de-
veloped and operated by the U.S. Depart-
ment of Defense provides an accurate cur-
rent vehicle position, normally using 4 or
more satellites, and in some cases 3 satel-
lites. The GPS system has a certain level
of inaccuracy. While the navigation sys-
tem will compensate for this most of the
time, occasional positioning errors of up to
300 feet (100 m) can and should be expec-
ted. Generally, position errors will be cor-
rected within a few seconds.
7U5001F
When your vehicle is receiving signals
from the satellites, the “GPS” mark ap-
pears at the top left of the screen.
The GPS signal may be physically ob-
structed, leading to inaccurate vehicle
position on the map display. Tunnels, tall
buildings, trucks, or even the placement of
objects on the instrument panel may ob-
struct the GPS signals.
The GPS satellites may not send signals
due to repairs or improvements being
made to them.
Even when the navigation system is re-
ceiving clear GPS signals, the vehicle
position may not be shown accurately or
inappropriate route guidance may occur in
some cases.
NOTICE
The installation of window tinting
may obstruct the GPS signals. Most
window tinting contains some metal-
lic content that will interfere with GPS
signal reception of the antenna in the
instrument panel. We advise against
the use of window tinting on vehicles
equipped with navigation systems.

(a) Accurate current vehicle position
may not be shown in the following
cases:
When driving on a small angled Y−
shaped road.
When driving on a winding road.
When driving on a slippery road such
as in sand, gravel, snow, etc.
When driving on a long straight road.
When freeway and surface streets run
in parallel.
After moving by ferry or vehicle carrier.
When a long route is searched during
high speed driving.
When driving without setting the cur-
rent position calibration correctly.
After repeating a change of direction by
going forward and backward, or turning
on a turntable in the parking lot.
When leaving a covered parking lot or
parking garage.
When a roof carrier is installed.
When driving with tire chains installed.
When the tires are worn.
After replacing a tire or tires.
When using tires that are smaller or
larger than the factory specifications.
When the tire pressure in any of the
four tires is not correct.
INFORMATION
If your vehicle cannot receive GPS
signals, you can correct the current
position manually. For information
on setting the current position
calibration, see “
 Current
position/tire change calibration” on
page 109.
(b) Inappropriate route guidance may
occur in the following cases:
When turning at an intersection off the
designated route guidance.
If you set more than one destination but
skip any of them, auto reroute will dis-
play a route returning to the destination
on the previous route.
When turning at an intersection for
which there is no route guidance.
When passing through an intersection,
there is no route guidance.
During auto reroute, the route guid-
ance may not be available for the next
turn to the right or left.
It may take a long time to operate auto
reroute during high speed driving. In
auto reroute, a detour route may be
shown.
After auto reroute, the route may not be
changed.
An unnecessary U−turn may be shown
or announced.
A location may have multiple names
and the system will announce one or
more.
Some routes may not be searched.
If the route to your destination includes
gravel, unpaved roads or alleys, the
route guidance may not be shown.
Your destination point might be shown
on the opposite side of the street.
When a portion of the route has regula-
tions prohibiting the entry of the vehicle
that vary by time or season or other
reasons.
The road and map data stored in your
navigation system may not be com-
plete or may not be the latest version.
