(a) When the presupport function is
in use
1Push the presupport switch
twice
2Sensor detection range
1. With the vehicle speed at less than
9 mph (15 km/h) and the vehicle on the
near side of the parking space, push the
presupport switch twice. Confirm that
the display has switched to the “Back
in mode” screen.
INFORMATION
 The mode will switch with each
push of the presupport switch.
 If the shift position is in “P” or if the
vehicle speed is 9 mph (15 km/h) or
above, two beeps will sound when
the presupport switch is pushed,
and the display will not change.
 If the shift position is in “R”, the
display will not change.
2. Move the vehicle to a position per-
pendicular to the parking space, and as
close as possible to the parked vehicle.
INFORMATION
Move the vehicle forward as slowly
as possible so that the steering
wheel can be turned as soon as the
chime sounds.
 To cancel the guidance function,
turn off the presupport function
by pushing the presupport switch
once.

3. As soon as the chime sounds, rotate
the wheel halfway or more and proceed
forwards.
INFORMATION
The chime sounds when the center of
the parking space can be seen direct-
ly beside the vehicle.
4. When two chimes sound, stop the
vehicle and straighten the steering
wheel.
INFORMATION
Move the vehicle forward as slowly
as possible after turning the steer-
ing wheel so that the vehicle can be
stopped as soon as the two chimes
sound.
 The chimes will not sound if the ve-
hicle does not arrive in a backing
up position after the steering
wheel has been maneuvered. If the
vehicle is stopped and the shift
position is shifted to “R” before the
chimes sound, the screen shown
in step 5 of “(b) When the presup-
port function is not in use” on page
235 is displayed.
5. Shift to “R”.
For operation after shifting to “R”, see step
6 of “(b) When the pre −support function is
not in use” on page 235.

(b) When the presupport function is
not in use
1. Move your vehicle slowly to a posi-
tion perpendicular to the parking
space, and as close as possible to the
parking space.
Positioning the vehicle perpendicular to
the parking space allows the angle of the
parking position to be identified easily.
2. Move your vehicle to a position
where you can see the center of the
parking space right besides you.
To facilitate the setting of the target parking
position, the front side sensors detect the
vehicles parked at the left and right of the
parking space and identify the target park-
ing position.
It is possible to identify the target parking
position even if there is only a vehicle
parked on one side of the parking space.
If no vehicle or small vehicles are parked
on both sides of the desired parking space,
stop with the steering wheel straight.
By stopping the vehicle here, you can
mostly identify the parking location, mak-
ing it easier to set the target parking posi-
tion.
Make sure the steering wheel is straight
when you stop. If not, the parking location
cannot be identified.
If you do not stop in front of the parking
space, the system will refer to the angle of
the vehicle relative to the target parking
space, and display the target parking posi-
tion (green or red frame) in the position
used last time the parking assist mode was
activated.

3. Position your vehicle so that you
can enter the parking space, then stop
the vehicle with the steering wheel
straight.
To enter the target parking space more ac-
curately, position your vehicle with a larger
heading angle.
4. Shift to “R”.
5. Touch on the screen.
6. Use the arrow to align the green
frame with the desired parking space,
then touch “OK”.
You can also move the green frame by
touching the screen (area other than the
arrow).
There are tricks to align the green frame.
See “  Tips for setting the target parking
position” on page 240.
Areas in which you are unable to park are
displayed in red.
If the frame is displayed in red, you cannot
use the parking assist mode to park in that
location. See “ When a red frame is dis-
played in the assist mode” on page 246.
When the green frame is displayed, if you
begin backing up without touching “OK”,
the message “Parking position has not
been set.” appears. If you continue to back
up, you will hear a warning tone and the
system will be disabled.
If the frame is red, there will be no guidance
even if you begin backing up.
If the orientation of the frame is opposite to
that of the target parking space, touch
.

238
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.)

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
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.
