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.

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.

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.

When a red frame is displayed in the
assist mode
If the frame turns red and the message
“Adjust the frame to the target.” is dis-
played while setting the target parking
position, you cannot use the assist mode.
In this situation, move the target parking
position, or move the position of the ve-
hicle.
The frame may be displayed in red, de-
pending on the location and angle of the
vehicle when “R” is selected.
Furthermore, even if the frame is displayed
in green, if you move the frame to a loca-
tion unsuitable for parking using the assist
mode, the frame will change to red.
When in the parking assist mode, if the
message “Steer to left (right) until the
frame becomes green.” is displayed, you
may use the assist mode by turning the
steering wheel. 1. Align
the frame with the target park-
ing position.
2. While stopped, turn the wheel to the
left (right) until the frame turns green
and “Too much force applied to the
steering wheel.” is displayed.
Turn the wheel slightly more than neces-
sary to overcome tire resistance.
If you turn the wheel too far, the direction
of turn displayed on the screen will re-
verse.
3. Touch “OK”.
Once you have turned the steering wheel,
you can no longer change the target park-
ing position. Be sure to align the frame be-
fore turning the steering wheel.
