■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.

■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. 507), 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.

■Function summary
When departing from a parallel parking position, select the direction
you would like to depart in, and steering wheel operation assist con-
trol will be provided to guide the vehicle to a position from which
you can take off.
With the shift position in P,
press the S-IPA switch,
select exit parallel parking
assist mode, and then oper-
ate the turn signal lever to
select the desired departure
direction.
Steering wheel auto opera-
tion starts when the shift
position is changed accord-
ing to guidance provided by
the system.
A sound is issued and a display is shown to notify you when the
vehicle reaches a position from which you can take off.
Depending on the condition of the parking space, guidance to starting
points for moving forward and backing up, as well as the steering wheel
auto operation, are repeated any time multi-turn maneuvering is neces-
sary from the time the steering wheel auto operation begins in step
up until the vehicle reaches a position from which it can take off.

Driving
Assume an ordinary driving
posture, rest your hands
lightly on the steering wheel
without applying any force,
directly confirm the safety of
the area to the front and
around the vehicle and
slowly proceed forward while
adjusting your speed by
depressing the brake pedal.
When this is done, a high-
pitched beep is emitted and
an indicator on the meter illu-
minates at the same time,
after which assist control will
start.
● When the steering wheel auto operation starts, the steering
wheel auto operation display ( P. 477) and assistance level
indicator ( P. 477) will be shown in the display area.
● To stop assist control, press the S-IPA switch.
● When the vehicle speed is too high, a sharp beeping sound is
emitted and assist control is stopped. ( P. 501)
● If the space turns out to be too narrow after assist control
starts, a sharp beeping sound is emitted and assist control is
stopped.
When a beep sounds once
and the stop display ( P. 477)
is shown on the display, stop
the vehicle.
Change the shift position to R.

■Water droplets during air conditioning operation
■ Setting confirmation screen
■ Operation of automatic airflow control
● In order to maintain a comfortable interior, airflow may be directed to seats
without passengers immediately after the hybrid system is started and at
other times depending on the outside temperature.
● After the hybrid system is started, if passengers move around inside or
enter/exit the vehicle, the system cannot accurately detect the presence of
passengers and automatic airflow control will not operate.
■ Operation of manual airflow control
Even if the function is manually switched to directing airflow to only the
front seats, when a rear seat is occupied, it may automatically direct air-
flow to all seats.
■ To return to automatic airflow control
With the indicator off, turn the power switch off.
After 60 minutes or more elapse, turn the power switch to ON.
■ Front seat concentrated airflow mode (S-FLOW) operation
The outside heat exchanger, accumulator
and air conditioning piping may incur con-
densation or frost may form. During or
after the air conditioning operation, water
droplets may fall from the vehicle. How-
ever, it is not a malfunction.
When changing the settings of the air
conditioning system, the setting confirma-
tion screen is shown as a pop-up on the
multi-information display.
Press of the meter control switches to
go back to the previous screen.
When is pressed, the front seat

■Operation of the air conditioning system when the blower customization
is set to “ECO”
●In the “ECO” mode, the air conditioning system is controlled as follows to
prioritize fuel efficiency:
• Engine speed and compressor operation controlled to restrict heating/
cooling capacity
• Fan speed restricted when automatic mode is selected
●To improve air conditioning performance, perform the following operations:
• Adjust the fan speed
• Adjust the temperature setting
• Set the blower customization to “FAST” or “NORMAL” mode.
●When the driving mode is set to Eco driving mode, the fan speed setting
mode will be changed to “ECO” mode automatically. Even in this case, the
fan speed control mode can be changed by pressing . (P. 418)
■When the outside temperature falls to nearly 0C (32F)
The dehumidification function may not operate even when is pressed.
■Ventilation and air conditioning odors
●To let the fresh air in, set the air conditioning system to the outside air mode.
●During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning system. This may then cause odor to
be emitted from the vents.
●In order to suppress odors that occur when the air conditioning system
starts, fresh air is automatically taken in when parked.
●To reduce potential odors from occurring, the start timing of the blower may
be delayed for a short period of time immediately after the air conditioning
system is started in automatic mode.
