2011 TOYOTA PRIUS Navigation Manual

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.

Do not allow organic solvent, car
wax, window cleaner or paint coat-
ing to adhere to the camera. If this
happens, wipe it off as soon as
possible.
If the camera is subjected to a colli-
sion, or the camera orientation
confirmation lines are not in line
with the bumper, it is likely that the
camera position or angle of instal-
lation has become crooked. See
your T oyota dealer as soon as pos-
sible.
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 attach any accessories
within the detection range of the
sensors.
A sensor may not operate properly
in the following situations.
There is ice, snow or mud on the
sensor. (When it is removed, the
normal operation will return.)
The sensor is frozen. (When the
sensor warms up, it will return to
normal.) At low temperatures in
particular, sensors that are fro-
zen may not detect a parked ve-
hicle.
When the vehicle is tilted.
In extreme hot or cold weather.
When driving on bumpy roads,
slopes, gravelled roads or grass.
Devices issuing ultrasonic
waves are operated around your
vehicle, such as a horn from
another vehicle, motorcycle en-
gine, air braking sound from
heavyduty vehicles.
When rain or water is splashed
over the vehicle.
When a radio antenna or fender
pole is mounted on your vehicle.
The sensor approaches too
close to a parked vehicle.
The sensor is covered in any
way.
The bumper or sensor receives a
strong impact.
NOTICE
When washing the vehicle, do not ap-
ply intensive burst of water to the
camera or camera area. Doing so may
result in the camera malfunction.

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.
∗: 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.
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.

Instructions given are only examples.
When and how much to turn the steer-
ing wheel will vary according to traffic
conditions, road surface conditions,
vehicle condition, etc. when parking.
It is necessary to be fully aware of this
before using the
advanced parking
guidance system.
Also, when parking, be sure to check
that the parking space will accommo-
date your vehicle before maneuvering
into it.
CAUTION
Depending on the circumstances of
the vehicle (number of passengers,
amount of luggage, etc.), the set tar-
get parking position displayed on the
screen may change. Be sure to check
visually behind and all around the ve-
hicle before proceeding.
(a) To activate the advanced parking
guidance system
To activate the advanced parking guid-
ance system, 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

the navigation system will display
another screen.
Even if the shift position is in “R”, if you
push any of the mode buttons around
the display, such as “MAP/VOICE” or
“INFO·PHONE” , the screen will switch
to that mode.
