NOTICE
■When using the memory
function ( P.406, 411)
●The memory function is a func-
tion which provides assistance
in parking in a previously regis-
tered parking space. If the con-
dition of the road surface,
vehicle, or surrounding area dif-
fers from when registration was
performed, the parking space
may not be able to be detected
correctly or assistance may not
be provided to the point that the
vehicle is fully parked.
●Do not register a parking space
in situations such as the follow-
ing, as the set parking space
may not be able to be registered
or assistance may not be possi-
ble later.
• When a camera lens is dirty or covered with water droplets
• When it is raining or snowing
• When the surrounding area is dark (at night, etc.)
●In situations such as the follow-
ing, it may not be possible to
register a parking space.
• When there is insufficient space between the road and parking
space
• When the road surface around the parking space does not
have any differences the sys-
tem can recognize
●If a parking space has been reg-
istered in situations such as the
following, assistance may not
be able to be started later or
assistance to the registered
position may not be possible.
• When shadows are cast on the parking space (there is a carport
over the parking space, etc.)
• When there are leaves, gar- bage, or other objects which will
likely move, in the parking
space
• When the road surface around the parking space has the same
repeating pattern (brick, etc.)

NOTICE
●In situations such as the follow-
ing, it may not be possible for
the system to provide assis-
tance to a registered parking
spot:
• When the appearance of the parking space is affected by the
shadow of the vehicle or trees
• When an object is detected in the registered parking space
• When a pedestrian or passing vehicle is detected during assis-
tance
• When the position the vehicle is stopped when assistance is
started differs from the position
when registration was per-
formed
• When the registered parking space cannot be reached due to
the existence of parking blocks,
etc.
• When the road surface around the parking space has changed
(road surface has degraded or
been resurfaced)
• When the sunlight conditions differ from when registration
was performed (due to weather
or time of day)
• When the sun is shining directly into a camera, such as in the
early morning or evening
• When the color or brightness of the road surface is uneven
• When a light is temporarily shined on the parking space
(lights of another vehicle, secu-
rity light, etc.)
• When the road surface around the parking space has the same
repeating pattern
• When there is a low protrusion on the road surface near the
parking space
• When the parking space is on a slope
• When a camera has been splashed by hot or cold water
and the lens has fogged up
• When a camera lens is dirty or covered with water droplets
• When accessories which obstruct the view of the camera
are installed
If assistance is ended during
registration, perform registration
again.
●When registering a parking
space to the memory function, if
the road surface cannot be
detected “No available parking
space to register” will be dis-
played.
●When using the memory func-
tion, make sure to stop immedi-
ately in front of the stop
position. Otherwise the parking
space may not be able to be
detected correctly or assis-
tance may not be provided to
the point that the vehicle is fully
parked.
●Do not use the memory function
if a camera has been subjected
to a strong impact or images of
the panoramic view monitor are
misaligned.
●If a camera has been replaced,
as the installation angle of the
camera will have c hanged, it will
be necessary to reregister park-
ing spaces of the memory func-
tion.
