Handle discs carefully, especially
when you are inserting them. Hold
them on the edge and do not bend the-
m. Avoid getting fingerprints on them,
particularly on the shiny side.
Dirt, scratches, warping, pin holes, or
other disc damage could cause the
player to skip or to repeat a section of
a track. (To see a pin hole, hold the disc
up to the light.)
Remove discs from the players when
you are not using them. Store them in
their plastic cases away from moisture,
heat, and direct sunlight.
6U5B98X
To clean a disc: Wipe it with a soft, lint−
free cloth that has been dampened with
water. Wipe in a straight line from the cen-
ter to the edge of the disc (not in circles).
Dry it with another soft, lint− free cloth. Do
not use a conventional record cleaner or
anti−static device.

CDR and CDRW discs
CD−R/CD−RW discs that have not
been subject to the “finalizing process”
(a process that allows discs to be
played on a conventional CD player)
cannot be played.
It may not be possible to play CD−
R/CD−RW discs recorded on a music
CD recorder or a personal computer
because of disc characteristics,
scratches or dirt on the disc, or dirt,
condensation, etc. on the lens of the
unit.
It may not be possible to play discs re-
corded on a personal computer de-
pending on the application settings and
the environment. Record with the cor-
rect format. (For details, contact the
appropriate application manufacturers
of the applications.)
CD−R/CD−RW discs may be damaged
by direct exposure to sunlight, high
temperatures or other storage condi-
tions. The unit may be unable to play
some damaged discs.
If you insert a CD−RW disc into the
MP3/WMA player, playback will begin
more slowly than with a conventional
CD or CD− R disc.
Recordings on CD −R/CD−RW cannot
be played using the DDCD (Double
Density CD) system. TERMS
Packet write—
This is a general term that describes the
process of writing data on
−demand to
CD−R, etc., in the same way that data is
written to floppy or hard discs.
ID3 Tag—
This is a method of embedding track −re-
lated information in an MP3 file. This em-
bedded information can include the track
title, the artist’s name, the album title, the
music genre, the year of production, com-
ments and other data. The contents can
be freely edited using software with ID3 tag
editing functions. Although the tags are re-
stricted to the number of characters, the in-
formation can be viewed when the track is
played back.
WMA Tag—
WMA files can contain a WMA tag that is
used in the same way as an ID3 tag. WMA
tags carry information such as track title,
artist name.
ISO 9660 format—
This is the international standard for the
formatting of CD−ROM folders and files.
For the ISO 9660 format, there are two lev-
els of regulations.
Level 1:
The file name is in 8.3 format (8 character
file names, with a 3 character file exten-
sion. File names must be composed of
one−byte capital letters and numbers. The
“_” symbol may also be included.)
Level 2:
The file name can have up to 31 characters
(including the separation mark “.” and file
extension). Each folder must contain few-
er than 8 hierarchies.

REAR VIEW MONITOR SYSTEM

The area displayed on the screen may
vary according to vehicle orientation or
road conditions.
The rear view monitor system cam-
era
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 dis-
tance of the image that appears on the
screen differs from the actual distance.
When the camera is used under fluores-
cent lights, sodium lights or mercury lights
etc., the lights and the illuminated areas
may appear to flicker.
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 camera has scratches or dirt
on it
When the sun or the beam of head-
lights is shining directly into the camera
lens

REAR VIEW MONITOR SYSTEM
206
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.

ADVANCED PARKING GUIDANCE SYSTEM
209
The advanced parking guidance sys-
tem helps back up parking by display-
ing a rearview image in order to pro-
vide a reference for back up
maneuvering, as well as automatically
controlling the steering wheel when
backing into a target parking position
set on the screen. The system will not
automatically back up or regulate
speed.
The advanced parking guidance system is
not an automatic parking system. It is a
system to assist back up parking.
As the system only assists with parking in
a set target parking position, there are
times when the system will be unable to
render this assistance, depending on fac-
tors such as road surface or vehicle condi-
tion, or the distance to the set target park-
ing position.
Depending on the characteristics of the
camera lens, the distance to or position of
people or obstacles shown on the screen
may differ slightly from actual conditions.
SELECTING A LANGUAGE
See “  Selecting a language” on page 254
for the procedure to select a language.
Once you select a language, the advanced
parking guidance system will indicate that
language until you select another lan-
guage.CAUTION
Never depend on the advanced
parking guidance 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.
Back up slowly, using the brake
pedal to control the vehicle’s
speed.
If you seem likely to hit nearby ve-
hicles, obstacles or people, de-
press the brake pedal to stop the
vehicle, and then disable the sys-
tem by touching on the
screen.
Use the system for flat spaces.
As the steering wheel moves auto-
matically in the parallel parking as-
sist mode and parking assist
mode, be aware of the following
points:
Keep clothing such as neckties,
scarves and long sleeves away
from the steering wheel, as they
may become entangled. Also,
keep children away from the
steering wheel.
If you have long fingernails, be
careful not to injure yourself
when the steering wheel moves.

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.

The advanced parking guidance
system camera
The advanced parking guidance system
camera is located on the back door as
shown in the illustration.
The camera uses a special lens. The dis-
tance of the image that appears on the
screen differs from the actual distance.
When the camera is used under fluores-
cent lights,
sodium lights or mercury lights
etc., the lights and the illuminated areas
may appear to flicker.
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
extremely 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) adheres to the camera
lens
When the camera has scratches or dirt
on it
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 CCD camera, may occur.

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.
If you install the antenna of a wireless de-
vice close to the camera, the screen image
may be affected by the electromagnetic
waves, and the system may not function
correctly. Install an antenna away from the
camera.
The method for adjusting the picture quali-
ty of the advanced parking guidance sys-
tem is the same as that for the navigation
screen.

CAUTION
When backing up, be sure to check
your surroundings and behind the
vehicle for safety, and back up
slowly, depressing the brake pedal
to control vehicle speed.
If a collision seems likely, depress
the brake pedal to stop the vehicle,
then disable the system by touch-
ing on the screen.
7. Once the vehicle is mostly within
the target parking position, voice guid-
ance will give a message, and parallel
parking assist mode will finish.
For safety, voice guidance is given slightly
before the target parking position. Further-
more, at that point system control will fin-
ish, so grip the steering wheel firmly, and
finish parking in the desired position, using
the brake to control the vehicle’s speed.
Check in front and behind the vehicle visu-
ally and check with the mirrors while back-
ing up.

Tips for setting the target parking
position
Useful information for setting the target
parking position (green frame)
THE DISPLAY POSITION OF THE
GREEN FRAME
The system decides the initial positioning
of the green frame by the position of the
parking space detected by the front side
sensors or the position of the vehicle when
it stops, and by detecting the white lines of
the parking space in the camera image to
identify the parking space location.
The front side sensors identify the parking
space location and the white lines near
that location are detected.
The front side sensors cannot identify the
parking space location, or the parking
space location may be misaligned in the
following situations.
A vehicle is parked at the back of the
parking space or the sensors cannot
detect a parked vehicle due to vehicle
shape etc.
The sensors cannot detect a pole or
wall beside the parking space.
The sensors detect a pedestrian or ob-
ject near the parking space.
If there are no vehicles parked on either
side of the target parking space when your
vehicle stops, the approximate parking
space location is identified, and the white
lines in that location are detected. For this
reason, stopping in front of the parking
space will make the detection of target
parking space’s white lines easier.
Successful detection of the parking
space’s white lines may not be possible,
depending on the shape of the line.

ADVANCED PARKING GUIDANCE SYSTEM
241
In the following circumstances, detec-
tion of the parking space lines on the
road surface may not be possible:
The lines are faded or dirty, making
them unclear.
The road surface is of a light color
which does not contrast well with the
white lines.
The parking space lines are a color oth-
er than white (yellow etc.).
The area is dark, for example at night
or in a covered parking lot.
During or after rain, when the road sur-
face is wet and reflects light, or puddles
have formed.
The sun is shining directly on the cam-
era, for example early morning or late
afternoon.
The parking space is covered with
snow or de −icing agent.
There are markings or maintenance
marks on the road surface.
The color or brightness of the road sur-
face is not uniform.
Hot or cold water has splashed on the
camera, and the lens is fogged.
There are dirt or water droplets on the
lens.
If the point at which you stop is correctly
identified, the green frame will display the
parking space accurately. If the white lines
of the parking space have not been cor-
rectly identified, the green frame will not
match the parking space even if you stop
in the correct location. In this case, adjust
the point at which you stop as needed. ALIGNING THE GREEN FRAME
There are two ways to align the green
frame with
the parking space, either using
the arrows on the screen, or by touching
the screen at points other than the arrows.
Using the arrows on the screen
By touching the arrows displayed on the
screen, you can move the green frame.
