ADVANCED PARKING GUIDANCE SYSTEM

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, attempt an approximate
match in an area where the warning flag
does not overlap with any parked vehicles
or obstacles.
You may adjust the target parking position
even after starting the parking assist
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
does not overlap any parked ve-
hicles or walls.
If there are obstacles in the green
frame or between your vehicle and
the parking space, or the warning
flag overlaps a parked vehicle or
wall, there is a danger of collision.
In this case, do not use the parking
assist mode.
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 parking assist
mode.

221
If the red area which denotes an
area unsuitable for parking over-
laps with the lines of the parking
space, you will be unable to park,
as the parking space is judged as
being an area unsuitable for park-
ing. Progress to a position where
the parking space lines do not
overlap with such an area.
7. 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.)

222
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”.
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.

8. Once the vehicle is mostly within
the target parking position, voice guid-
ance will give a message, and 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
224
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.

Directly touching the target point
By touching the point you wish to move the
frame to, you can move the green frame.
1. Touch the front edge of the place
you wish to move.
2. The frame will be moved as shown.
If you touch the following areas, the green
frame will not move:
The area surrounding the arrows.
The area near the lower touch−screen
button on the screen.
Areas too far away to park in the range
of 31.2 ft. (9.5 m) or more behind, and/
or either left or right from the current
position. IF THE PARKING SPACE AND THE
GREEN FRAME DO NOT MATCH
If the lines of the parking space are wider
than
the green frame, position the frame so
that the difference between the frame and
the parking space lines is equal on both
sides.
