on/off. (P.330)
■When the outside temperature
exceeds 75°F (24°C) and the air
conditioning system is on
In order to reduce the air condition-
ing power consumption, the air con-
ditioning system may switch to
recirculated air mode automatically.
This may also reduce fuel consump-
tion.
■Fogging up of the windows
●The windows will easily fog up
when the humidity in the vehicle is
high. Turning “A/C” on will dehu-
midify the air from the outlets and
defog the windshield effectively.
●If you turn “A/C” off, the windows
may fog up more easily.
■Eco air conditioning mode
When Eco drive mode is selected
using the driving mode select
switch, eco air conditioning mode
turns on.
When a drive mode other than Eco
drive mode is sele cted, eco air con-
ditioning mode may turn off.
■Operation of the air condition-
ing system in Eco drive mode
●In Eco drive mode, the air condi-
tioning system is controlled as fol-
lows to prioritize fuel efficiency:
• Engine speed and compressor operation controlled to restrict
heating/cooling capacity
• Fan speed restri cted when auto-
matic mode is selected
●To improve air conditioning perfor-
mance, perform the following
operations:
• Adjust the fan speed
• Turn off Eco drive mode ( P.308)
• Turn off Eco air conditioning mode
●When the driving mode is set to
Eco driving mode, the air condi-
tioning eco mode will be turned on
automatically. Even in this case,
the air conditioning eco mode can
be turned off by pressing the Eco
air conditioning mode switch.
■When the outside temperature
is low
The dehumidification function may
not operate even when “A/C” is
pressed.

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. 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
in the rear seats
 The windshield defogger is
not operating
While operating, the indicator illumi-
nates on the S-FLOW mode switch.
■Manually turning front seat

trol screen or press the S-FLOW
mode switch on the air condi-
tioning operation panel and

■Operation of automatic airflow
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 accura tely detect the
