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.

ADVANCED PARKING GUIDANCE SYSTEM
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.

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 .

ADVANCED PARKING GUIDANCE SYSTEM
231
Parking assist mode assists the driver
with perpendicular parking by automat-
ically controlling the steering wheel
when backing up, in order to park in the
target position set on the screen.
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 you seem likely to hit nearby ve-
hicles, obstacles or people, de-
press the brake pedal to stop the
vehicle, then disable the system by
touching on the screen.
As the system only assists with parking in
a set target parking position, there are
times when the system will be unable to
render this assistance, depending on fac-
tors such as road surface or vehicle condi-
tion, or the distance to the set target park-
ing position.
Use the system with full understanding of
the fact.
If a message is displayed while maneuver-
ing, follow the procedures outlined in “—
What to do when this sort of message is
displayed” on page 243.
The illustrations here describe the proce-
dure for pulling into a parking space on the
right. For pulling into a parking space on
the left, substitute left for right and vice ver-
sa in all steps.
The operating method differs depending
on whether or not the pre− support function
is in use. PRESUPPORT FUNCTION
The presupport function can be used
when another vehicle is parked on the
near side of the intended parking
space. This function uses a tone to give
parking guidance.
Guidance will not be given if the detected
space is narrow.

INFORMATION
If only one vehicle is parked, the pre
support system cannot be used to
park on the right side of the vehicle.
Parking between two parked vehicles
1Push the presupport switch
twice
2Identify a parking space
3Get into a position to maneuver
the steering wheel
4Get into a position to begin back
up maneuvering
INFORMATION
To allow the presupport system
to activate accurately, move the ve-
hicle as slowly as possible (at a
speed that will allow the vehicle to
be stopped suddenly).
 The function cannot be used if the
shift position is in “P” or “R”, or if
the vehicle speed is greater than 9
mph (15 km/h).
 In order to identify parking spaces
and detect parked vehicles using
the sensors on both sides of the
front bumper, guidance cannot be
given if a space is not detected.
 Parking space guidance and
searching continues until the ve-
hicle speed is greater than 9 mph
(15 km/h) or until the function is
turned off by pushing the presup-
port switch.
