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.

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.

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.

(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.

ADVANCED PARKING GUIDANCE SYSTEM
234
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
.
