ADVANCED PARKING GUIDANCE SYSTEM
217
In any of the following situations, there
is a margin of error between the set tar-
get parking position on the screen and
the actual distance/course on the road.
When the grade behind the vehicle
slopes up sharply, objects appear to
be farther away than they actually
are.
— Driving precautions

When the grade behind the vehicle
slopes down sharply, objects ap-
pear to be closer than they actually
are.
When any part of the vehicle sags
due to the number of passengers or
the distribution of the load, there is
a margin of error between the set
target parking position on the
screen and the actual distance/
course on the road.

ADVANCED PARKING GUIDANCE SYSTEM
219
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 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 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.

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).
 If only one vehicle is parked, the
presupport system cannot be
used.
 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
once
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 once. Confirm that
the display has switched to the “Paral-
lel parking mode” screen.

ADVANCED PARKING GUIDANCE SYSTEM
221
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.
1Approx. 3 ft. (1 m)
2Desired parking location
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-
ing the presupport switch twice.

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.

(b) When the presupport function is
not in use
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.
