Rear view monitor system
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 inside rear view
mirror.
To display the rear view image on the
screen, place the selector lever in the “R”
position when the ignition key 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 tail
gate 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 consult
your Toyota dealer. If you replace the tires,
the area displayed on the screen may
change.

207 AREA DISPLAYED ON SCREEN
Image is displayed approximately level on
screen.
XS00115
Corners of bumper On screen
The area detected by the camera is lim-
ited. The camera does not detect ob-
jects which are close to either corner of
the bumper or under the bumper.
The area displayed on the screen may
vary according to vehicle orientation
or road conditions.

THE REAR VIEW MONITOR SYSTEM
CAMERA
The rear view monitor system camera is lo-
cated on the tail gate as shown in the illustra-
tion. The camera uses a special lens. The dis-
tance of the image that appears on the screen
differs from the actual distance.
In the following cases, it may become difficult
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 ex-
ample, when it rains)

208
When foreign matter (for example, snow
or mud) is adhering to the camera
When the sun or the beam of headlights is
shining directly into the camera lens

Check surroundings for safety.
If a bright light (for example, sunlight reflected
off the vehicle body) is picked up by the cam-
era, the smear effect
∗ peculiar to the camera
may occur.
∗: Smear effect—A phenomenon that occurs
when a bright light (for example, sunlight re-
flected off the vehicle body) is picked up by
the camera; when transmitted by the camera,
the light source appears to have a vertical
streak above and below it.

Limitations of the navigation
system
This navigation system calculates the cur-
rent vehicle position using satellite sig-
nals, various vehicle signals, map data,
etc. However, the accurate position may
not be shown depending on the satellite
condition, road configuration, vehicle
condition or other circumstances.
The Global Positioning System (GPS) devel-
oped and operated by the U.S. Department of
Defense provides an accurate current vehicle
position, normally using 4 or more satellites,
and in some cases 3 satellites. The GPS sys-
tem has a certain level of inaccuracy. While
the navigation system will compensate for
this most of the time, occasional positioning
errors of up to 300 feet (100 m) can and
should be expected. Generally, position er-
rors will be corrected within a few seconds.
7U5027
When your vehicle is receiving signals from
the satellites, the “GPS” mark appears at the
top left of the screen.
The GPS signal may be physically ob-
structed, leading to inaccurate vehicle posi-
tion on the map display. Tunnels, tall build-
ings, trucks, or even the placement of objects
on the instrument panel may obstruct 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 receiving
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 metallic content
that will interfere with GPS signal recep-
tion of the antenna in the instrument
panel. We advise against the use of win-
dow tinting on vehicles equipped with
navigation systems.

211 (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 current
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 87.
(b) Inappropriate route guidance may oc-
cur 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 display
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 guidance
may not be available for the next turn to
the right or left.
It may take a long time to operate auto re-
route 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.
