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.

sides.

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-
