●To reduce potential odors from
occurring:
• It is recommended that the air
conditioning system be set to out-
side air mode prio r to turning the
vehicle off.
• The start timing of the blower may be delayed for a short period of
time immediately after the air con-
ditioning system is started in auto-
matic mode.
●When parking, the system auto-
matically switches to outside air
mode to encourage better air cir-
culation throughout the vehicle,
helping to reduce odors that occur
when starting the vehicle.
1 Press the automatic mode
switch.
The dehumidification function
begins to operate. Air outlets and
fan speed are automatically
adjusted according to the tempera-
ture setting and humidity.
2Adjust the temperature set-
ting.
3 To stop the operation, press
the “OFF” switch.
If the fan speed setting or air
flow modes are operated, the
automatic mode indicator goes
off. However, automatic mode
for functions other than that
operated is maintained.
■Using automatic mode
Fan speed is adjusted automati-
cally according to the temperature
setting and the ambient conditions.
Therefore, the fan may stop for a
while until warm or cool air is ready
to flow immediately after the auto-
matic mode switch is pressed.
This function automatically con-
trols the air conditioning airflow
so that priority is given to the
front seats. When the front pas-
senger seat is not occupied, air-
flow may switch to only the
driver’s seat. Unnecessary air
conditioning is suppressed, con-
tributing to increased fuel effi-
ciency.
Front seat concentrated airflow
mode operates in the following
situations.
 No passengers are detected
Using automatic mode
NOTICE
■Humidity sensor
In order to detect fog on the wind-
shield, a sensor which monitors
the temperature of the windshield,
the surround humidity, etc. is
installed.
Follow these points to avoid dam-
aging the sensor:
●Do not disassemble the sensor
●Do not spray glass cleaner on
the sensor or subject it to strong
impacts
●Do not stick anything on the
sensor

control
●In order to maintain a comfortable
interior, airflow may be directed to
seats without passengers immedi-
ately after the hybrid system is
started and at other times depend-
ing on the outside temperature.
●After the hybrid system is started,
if passengers move around inside
or enter/exit the vehicle, the sys-
tem cannot accurately detect the
presence of passengers and auto-
matic airflow control will not oper-
ate.
■Operation of manual airflow
control

switched to directing airflow to only
the front seats, when a rear seat is
occupied, it may automatically direct
airflow to all seats.
■To return to automatic airflow
control
