driven safely and possibly cause
an accident.
●Do not use this system in situa-
tions such as the following:
• When in areas other than com- mon parking spaces
• When the surface of the parking space is sand or gravel and is
not clearly defined with parking
space lines
• When the parking space is not level, such as when on a slope
or has differences in height
• Mechanical parking system
• Parking lot with a device which raises to contact the bottom of
the vehicle
• When the road surface is fro- zen, slick, or covered with snow
• When it is extremely hot and the asphalt is melting
• When there are objects around the vehicle
• When there is an object between your vehicle and the
target parking spot or within the
target parking spot (within the
displayed blue box)
• When there is a gutter between your vehicle and the target park-
ing space or within the target
parking spot (within the dis-
played blue box)
• When there is a hole or gutter in the exit direction
• When in high pedestrian or vehicle traffic areas
• When the parking space is in a location that is difficult to park in
(too narrow for your vehicle,
etc.)
• When images are unclear due to dirt or snow attached to the
camera lens, light being shined
into the camera or shadows
• When tire chains or a compact spare tire is installed to the vehi-

■Precautions for use
For details on the following, refer to
“Panoramic view monitor” of “Park-
ing assist system” in the “MULTIME-
DIA OWNER’S MANUAL”.
●Displayable range of the screens
●Cameras
●Differences between displayed
images and the actual road
●Differences between displayed
images and the actual objects
■Detection range of the cameras
and sensors
●If a parked vehicle is behind the
target parking space and the dis-
tance between it and the vehicle
becomes far, it may no longer be
able to be detected. Depending on
shape or condition of a parked
vehicle, the detection range may
become short or the vehicle may
not be detected.
●Objects other than parked vehi-
cles, such as columns, walls, etc.,
may not be detected. Also, if they
are detected, they may cause the
target parking space to be mis-
aligned.
■Situations in which parking
space lines may not be recog-
nized properly
●In situations such as the following,
parking space lines on the road
surface may not be detected:
• When the parking space does not use lines (parking space boundar-
ies are marked with rope, blocks,
etc.)
• When the parking space lines are
faded or dirty, making them
unclear
• When the road surface is bright, such as concrete, and the contrast
between it and the white parking
space lines is small
• When the parking space lines are
any color other than yellow or
white
• When the area surrounding the
parking space is dark, such as at night, in an underground parking
lot, parking garage, etc.
• When it is rainin g or has rained
and the road surface is wet and

ered with snow or de-icing agent
• When there marks from repairs or other marks on the road surface,
or there is a traffic bollard, or other
object on the road surface
• When the color or brightness of
the road surface is uneven
• When a camera has been splashed by hot or cold water and
the lens has fogged up
• When the appearance of the park- ing space is affected by the
shadow of the vehicle or trees
• When a camera lens is dirty or covered with wa ter droplets
●In situations such as the following,
the target parking space may not
be recognized correctly:
• When there marks from repairs or other marks on the road surface,
or there is a parking block, traffic
bollard, or other object on the road
surface
• When it is rainin g or has rained
and the road surface is wet and
reflective or there are puddles
• When the area around the vehicle is dark or backlit
• When the color or brightness of
the road surface is uneven
• When the parking space is on a slope
• When there are diagonal lines (access aisle) near the parking
space
• When the appearance of the park- ing space is affected by the

steering wheel is operated,
“Advanced Park Finished” will be
displayed and assistance will end.
As assistance will end while the
vehicle is moving, grip the steering
wheel and drive forward.
If the steering wheel is not oper-
ated, the vehicle will stop at the exit
position. Assistance can be ended

Maintenance and care
stick.
1Park the vehicle on level
ground. After warming up the
engine and turning off the
hybrid system, wait about 5
minutes for the oil to drain
back into the bottom of the
engine.
2 Holding a rag under the end,
pull the dipstick out.
3 Wipe the dipstick clean.
4 Reinsert the dipstick fully.
5 Holding a rag under the end,
pull the dipstick out and
check whether the oil level is
above low level mark.
Low level mark
The shape of the dipstick may differ
depending on the type of vehicle or
engine.
6Wipe the dipstick and reinsert
it fully.
■Engine oil consumption
A certain amount of engine oil will
be consumed while driving. In the
following situations, oil consump-
tion may increase, and engine oil
may need to be re filled in between
oil maintenance intervals.
●When the engine is new, for
example directly after purchasing
the vehicle or after replacing the
engine
●If low quality oil or oil of an inap-
propriate viscosity is used
●When driving at high engine
speeds or with a heavy load, or
when driving while accelerating or
decelerating frequently
●When leaving the engine idling for
a long time, or when driving fre-
quently through heavy traffic
■Engine oil level rise
If the vehicle is repeatedly driven
without the engine warmed up,
moisture caused by dew condensa-
tion inside the engine or fuel which
did not burn mixes into the engine
oil, resulting in a rise in engine oil
level.
However, this is not a malfunction.
For example, the engine become
difficult to be warmed up in the fol-
lowing situations.
●When driving a short distance
●When driving at a low speed
●When the outside temperature is
low
When checking the engine oil, make

■If air flow from the vents
decreases dramatically
The filter may be clogged. Check
the filter and replace if necessary.
WARNING
■When replacing the air condi-
tioning filter
Check that the charging connec-
tor is not connected. Failure to do
so may result in the air condition-
ing system operating during the
procedure due to the “Battery
Cooler”, possibly resulting in
injury.
NOTICE
■When using the air condition-
ing system
Make sure that a filter is always
installed. Using the air condition-
ing system without a filter may
cause damage to the system.
■When removing the glove box
Always follow the specified proce-
dure to remove the glove box
(  P.535). If the glove box is
removed without following the
specified procedure, the hinge of
the glove box may become dam-
aged.
■To prevent damage to the fil-
ter cover
When moving the filter cover in
the direction of arrow to release
the fitting, pay attention not to
apply excessive force to the
claws. Otherwise, the claws may
be damaged.
