ADVANCED PARKING GUIDANCE SYSTEM

Parallel parking assist mode assists
the driver with parallel parking by auto-
matically 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 226.
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 there is a space between two
parked vehicles. If a parking space is
detected, this function will inform the
driver using a tone when the vehicle is
in a position to begin backing up, and
guides the vehicle to a position from
which assistance can be given.
Guidance will not be given if the detected
space is narrow.

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.

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.

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 .

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

The operating method differs depending

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 sw itch 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 “R”,
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.
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.
