2011 TOYOTA PRIUS park assist

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.

(b) Disabling the advanced parking
guidance system
When in the parking assist mode or par-
allel parking assist mode, in the follow-
ing case the voice guidance will say
“The guidance has been canceled”, a
message will be displayed, and the sys-
tem will be disabled. For displayed
message, see page 243.
After the following operations
Moving the steering wheel
Using the accelerator
Moving the shift position out of “R”
Applying the parking brake
Switching the screen display In the following situation
If the vehicle slips forward or stops af-
ter taking your foot off the brake pedal
If the backing speed is too fast
If normal assistance cannot be ren-
dered
due to worn tires or low tire infla-
tion pressure
If the target parking position has not
been confirmed on the target parking
position setting screen before backing
up

If the system temperature protection
function operates
If the system is disabled while backing up,
grip the steering wheel firmly and depress
the brake pedal to bring the vehicle to a
halt. The system has been completely dis-
abled, so you may either start again from
the beginning, or if you wish to finish park-
ing manually, be sure to operate the steer-
ing wheel as you would normally.
If a hands− free phone call is received, the
hands −free screen will be displayed, and
the system will be disabled.

Parallel parking assist mode assists
the driver with parallel parking by auto-
matically controlling the steering wheel
when backing up, in order to park in the
target position set on the 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 you seem likely to hit nearby ve-
hicles, obstacles or people, de-
press the brake pedal to stop the
vehicle, then disable the system by
touching on the screen.
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.
Use the system with full understanding of
the fact.
If a message is displayed while maneuver-
ing, follow the procedures outlined in “—
What to do when this sort of message is
displayed” on page 243.
The illustrations here describe the proce-
dure for pulling into a parking space on the
right. For pulling into a parking space on
the left, substitute left for right and vice ver-
sa in all steps.
The operating method differs depending
on whether or not the pre− support function
is in use. PRESUPPORT FUNCTION
The presupport function can be used
when there is a space between two
parked vehicles. If a parking space is
detected, this function will inform the
driver using a tone when the vehicle is
in a position to begin backing up, and
guides the vehicle to a position from
which assistance can be given.
Guidance will not be given if the detected
space is narrow.

CAUTION
Be sure to stop the vehicle parallel to
the road or shoulder. If the vehicle is
not parallel, the assist location will be
very near the shoulder. If it looks like
the vehicle will hit or mount the
shoulder, depress the brake pedal to
stop the vehicle, and touch on
the screen to deactivate the system.
If there is no leading parked vehicle, the
system will display the target parking posi-
tion (green or red frame) in the position
used last time the parallel parking assist
mode was activated. 3. Shift to “R”.
4. Touch on the screen.
5. Use the arrow to align the green
frame with your target parking space,
and touch “OK”.
You can also move the green frame by
touching the screen (area other than the
arrows).
There are tricks to align the green frame.
See “
 Tips for setting the target parking
position” on page 228.
If the frame is displayed in red, you cannot
use the parallel parking assist mode to
park in that location. See “  When a red
frame is displayed in the assist mode” on
page 246.

ADVANCED PARKING GUIDANCE SYSTEM
225
When the green frame is displayed, if you
begin backing up without touching “OK”,
the message “Parking position has not
been set.” appears. If you continue to back
up, you will hear a warning tone and the
system will be disabled.
If the frame is red, there will be no guidance
even if you begin backing up.
If the orientation of the frame is opposite to
that of the target parking space, touch
.
There may be times when, due to image
distortion, the green frame does not match
the parking space lines on the road sur-
face. In this case, use the warning flag and
green extension guide line to set the target
parking position.
You may adjust the target parking position
even after starting the parallel parking as-
sist mode.
CAUTION
Always check that there are no ob-
stacles in the green frame or be-
tween your vehicle and the parking
space, and that the warning flag
and extension guide line do not
overlap any parked vehicles or
walls.
If there are obstacles in the green
frame or between your vehicle and
the parking space, or the warning
flag or extension guide line over-
laps a parked vehicle or wall, there
is a danger of collision. In this
case, do not use the parallel park-
ing assist mode. The same applies
if the green frame overlaps the
shoulder.
The warning flag is only a guide.
Be sure to directly check your sur-
roundings and behind the vehicle
for safety, and back up carefully.
If the road surface has level varia-
tions or a gradient between the
starting position and target park-
ing position, it will not be possible
to correctly set the location, which
may cause the parking position to
be misaligned or crooked. In this
case, do not use the parallel park-
ing assist mode.

6. Position yourself as you would
when backing up normally, and rest
your hands on the steering wheel with-
out applying any pressure. Check your
surroundings and behind the vehicle
for safety, and slowly back up, using
the brake pedal to control the vehicle’s
speed.
If you touch
, assistance is can-
celed.
If the vehicle’s backing up speed is too
fast, a warning tone will sound and the
message “Speed is too fast.” will be dis-
played. If you continue to back up at that
speed, the system will be disabled. Back
up at a speed that does not cause the
warning tone to sound.
The green frame displayed on the screen
is approximately the same size as your ve-
hicle. (The green frame displayed when
setting the target parking position is the
size of a normal parking space.)
You can change the target parking position
by touching
. If you are backing up,
or have already moved close to the target
parking position,
will turn gray, and
you will be unable to change the target.
Touch the arrows to move the target park-
ing position, and then touch “OK”.
You can only move the target parking posi-
tion left or right, and the warning flag will
not move even if you adjust the target park-
ing position.

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.
