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 paral-
lel to the road (or road shoulder) that is
also approximately 3 ft. (1 m) away from
the parked vehicle, and then proceed
straight forward.
INFORMATION
To cancel the guidance function, turn
off the presupport function by push-

3. Stop the vehicle when two chimes
sound.
INFORMATION
Two chimes sound when the ve-
hicle reaches a position from
which the front edge of the leading
parked vehicle can be seen along-
side.
 Move the vehicle forward as slowly
as possible 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. If the vehicle is
stopped and the shift position is
shifted to “R” before the chimes
sound, the screen shown in step 4
of “(b) When the presupport func-
tion is not in use” on page 223 is
displayed.
4. Shift to “R”.
For operation after shifting to “R”, see step
5 of “(b) When the pre −support function is
not in use” on page 223.

1Approx. 3 ft. (1 m)
2Desired parking location
1. Move your vehicle slowly to a posi-
tion parallel to the road or shoulder
approximately 3 ft. (1 m) away from
parked vehicles.
To facilitate the setting of the target parking
position, the front side sensors detect the
vehicles parked in front of and behind the
parking space and identify the target park-
ing position.
2. Stop your vehicle in a position
where you can see the front edge of the
leading parked vehicle right beside
you, with the steering wheel straight.

ADVANCED PARKING GUIDANCE SYSTEM
224
CAUTION
Be sure to stop the vehicle parallel to
the road or shoulder. If the vehicle is
not parallel, the assist location will be
very near the shoulder. If it looks like
the vehicle will hit or mount the
shoulder, depress the brake pedal to
stop the vehicle, and touch on
the screen to deactivate the system.
If there is no leading parked vehicle, the
system will display the target parking posi-
tion (green or red frame) in the position
used last time the parallel parking assist
mode was activated. 3. Shift to “R”.
4. Touch on the screen.
5. Use the arrow to align the green
frame with your target parking space,
and touch “OK”.
You can also move the green frame by
touching the screen (area other than the
arrows).
There are tricks to align the green frame.
See “
 Tips for setting the target parking
position” on page 228.
If the frame is displayed in red, you cannot
use the parallel parking assist mode to
park in that location. See “  When a red
frame is displayed in the assist mode” on
page 246.

ADVANCED PARKING GUIDANCE SYSTEM
225
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
.
There may be times when, due to image
distortion, the green frame does not match
the parking space lines on the road sur-
face. In this case, use the warning flag and
green extension guide line to set the target
parking position.
You may adjust the target parking position
even after starting the parallel parking as-
sist mode.
CAUTION
Always check that there are no ob-
stacles in the green frame or be-
tween your vehicle and the parking
space, and that the warning flag
and extension guide line do not
overlap any parked vehicles or
walls.
If there are obstacles in the green
frame or between your vehicle and
the parking space, or the warning
flag or extension guide line over-
laps a parked vehicle or wall, there
is a danger of collision. In this
case, do not use the parallel park-
ing assist mode. The same applies
if the green frame overlaps the
shoulder.
The warning flag is only a guide.
Be sure to directly check your sur-
roundings and behind the vehicle
for safety, and back up carefully.
If the road surface has level varia-
tions or a gradient between the
starting position and target park-
ing position, it will not be possible
to correctly set the location, which
may cause the parking position to
be misaligned or crooked. In this
case, do not use the parallel park-
ing assist mode.

6. 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.)
You can change the target parking position
by touching
. If you are backing up,
or have already moved close to the target
parking position,
will turn gray, and
you will be unable to change the target.
Touch the arrows to move the target park-
ing position, and then touch “OK”.
You can only move the target parking posi-
tion left or right, and the warning flag will
not move even if you adjust the target park-
ing position.

227
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)
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.
Adjusting the left
−right alignment first will
make subsequent alignment easier.

ADVANCED PARKING GUIDANCE SYSTEM
229
Directly touching the target point
By touching the point you wish to move the
frame to, you can move the green frame.
1. Touch the front edge of the place
you wish to move.
2. The frame will be moved as shown.
If you touch the following areas, the green
frame will not move:
The area surrounding the arrows.
The area near the lower touch−screen
button on the screen.
Areas too far away to park in the range
of 34.4 ft. (10.5 m) or more behind the
current position, and/or 16.4 ft. (5.0 m)
or more either left or right from the cur-
rent position. IF THERE IS A SLOPE IN THE ROAD
The assisted parking position will
move left
or right of the set target parking position.

ADVANCED PARKING GUIDANCE SYSTEM
230
In this case, if you align the warning flag
with the rear of the forward parked vehicle,
and the green extension guide line with the
lower edge of the parked vehicle’s rear
wheel when setting the target parking posi-
tion, the left side of your vehicle will be
roughly in line with the left side of the front
parked vehicle once assisted parking is
complete. If you are parallel parking on the
opposite side of the road, left and right will
be reversed.1Narrow
CAUTION
If the parked vehicle is narrow, or
parked close to the shoulder, the as-
sisted parking position may be quite
close to the shoulder. If the vehicle
seems likely to hit or mount the
shoulder, depress the brake pedal to
stop the vehicle, and disable the sys-
tem by touching .
