●There is a system malfunction
●System determined that the parking environment is not suitable
for assist to continue
When assist control is canceled, firmly grasp the steering wheel,
depress the brake pedal and stop the vehicle.
Start again from the beginning, as the system will already be can-
celed. When continuing to park manually, operate the steering
wheel as you normally would.
■Assist control is stopped when
●The steering wheel is operated
●The vehicle speed exceeds 7 km/h (4 mph) during assist control
●The Parking Support Brake function operates
When assist control is stopped, it can be resumed by following the
guidance shown on the screen.
■If the vehicle speed is about to exceed the speed limit during assist con-
trol
Canceling or stopping assist mode

■Function summary
If a parking space can be detected, you will be guided forward until
you reach the assist control starting position, and then the parallel
parking assist mode can be used. Furthermore, depending on the
parking space and other conditions, multi-turn maneuvering assist
control is also provided if necessary.
Continue moving forward
with the vehicle parallel to
the curb or road, and stop so
that the center of the target
parking spot appears nearly
perpendicular to the vehicle.
Then press the S-IPA switch
1 time to select the parallel
parking assist mode.
Travel straight ahead paral-
lel with the road or curb so
that the parking space is
detected.
A sound is issued and a display is shown to notify you when the
vehicle reaches a position where assist control can be used to
begin backing up from, and then when the shift position is
changed according to guidance provided by the system, steering
wheel auto operation begins.
If the detected parking space or road width (distance to the side of the
road across from the parking space) is narrow, or if there are obstacles
in front of the vehicle, guidance will not be issued.
Parking is complete
This completes the assist mode. Depending on the condition of the
parking space, guidance to starting points for moving forward and back-
ing up, as well as the steering wheel auto operation, are repeated any
time multi-turn maneuvering is necessary following step from the
time the vehicle begins backing up until parking completes.

When a beep sounds once
and the stop display ( P. 409)
is shown on the display, stop
the vehicle.
When the shift position is changed to R, a high-pitched beep is
emitted and assist control will start.
● When the steering wheel auto operation starts, the steering
wheel auto operation display ( P. 409) and assistance level
indicator ( P. 409) will be shown in the display area.
● To stop assist control, press the S-IPA switch.
Assume an ordinary posture for backing up, rest your hands
lightly on the steering wheel without applying any force, directly
confirm the safety of the area to the rear and around the vehicle,
confirm that there are no obstacles in the parking space, and
slowly back up while adjusting your speed by depressing the
brake pedal.
● When backing up too quickly, a sharp beeping sound is emit-
ted and assist control is stopped. ( P. 410)
● When the vehicle cannot be cleanly entered within the target
parking spot on the first try and multi-turn maneuvering is nec-
essary, proceed to step .
When multi-turn maneuvering is not necessary, proceed to
step .

When the vehicle is almost entirely within the target parking spot,
a high-pitched beep is emitted and the stop display is shown on
the display, stop the vehicle.
This completes the parallel parking assist mode.
●After stopping, feel free to maneuver the vehicle to reach the
desired parking spot.
●Be sure to back up while checking the area to the front and
rear of the vehicle directly and by using the mirrors.
■Parallel parking assist mode operating conditions
●In order to operate the parallel parking assist mode correctly, drive slowly (at
a speed at which the vehicle can be quickly stopped) parallel to the road (or
shoulder) while maintaining a distance of approximately 1 m (3.3 ft.) to any
parked vehicles.
●The function cannot be used when the vehicle speed is approximately
30 km/h (19 mph) or higher.
●The front side sensors and rear side sensors are used to detect parked
vehicles and determine the parking spot. Therefore, when detection is not
possible (P. 439), guidance is not issued.
●If there are no parked vehicles, the parking spot cannot be determined.
Therefore, the parallel parking assist mode cannot be operated.
●If unable to detect the environment surrounding the parking space, the par-
allel parking assist mode may not be able to operate.
●Guidance will continue until the vehicle speed meets or exceeds approxi-
mately 30 km/h (19 mph) or the function is turned off using the S-IPA switch.
■Timing for pressing the S-IPA switch
In the following cases, the assist mode may also operate during the steps
taken to park using the parallel parking assist mode. However, in these
cases, conduct parking procedures according to the information on the multi-
information display.
●In step the S-IPA switch is pressed after already passing over the target
parking spot.
If the vehicle is not stopped in step , pressing the S-IPA switch 1 time
while the vehicle is in motion allows you to select “Parallel Parking” and
proceed directly to step .
●The vehicle is moved up to the position in step without the S-IPA switch
being pressed. Then the S-IPA switch is pressed after having changed the
shift position to R.

NOTICE
●If the road surface has any dips or inclines, the target parking spot cannot
be correctly set. Therefore, the vehicle may be parked at an angle or may
deviate from the parking spot. In these cases, do not use the parallel park-
ing assist mode.
● When there is a wall or other obstacle on the inner side of the parking
space, or when another parked vehicle extends into the road from its park-
ing spot, the target parking spot may be set in a position that juts out
slightly into the road.
● Depending on the surrounding environment, such as other parked vehi-
cles, the vehicle may be parked at an angle or may deviate from the park-
ing spot. Manually adjust vehi cle alignment as necessary.
● The system provides assistance to guide the vehicle based on position of
adjacent vehicles, even if there are obstacles, bumps, drops or curb
stones in the parking space.
If it seems the vehicle may make contact, stop the vehicle by depressing
the brake pedal, and then press the S-IPA switch to turn off the system.
● It may not be possible to detect objects that are low to the ground. Directly
confirm the safety of your surroundings and, if it seems the vehicle may
make contact with an obstacle, stop the vehicle by depressing the brake
pedal.
● When the other parked vehicle is nar-
row or parked extremely close to the
curb, assist control will also guide the
vehicle to a position close to the curb.
If it seems the vehicle may make con-
tact with the curb or any other obsta-
cles, or if it seems the tire position will
deviate from the intended parking spot,
stop the vehicle by depressing the
brake pedal, and then press the S-IPA
switch to turn off the system.
