5-2. Using the air conditioning system and defogger
Select the S-FLOW mode
(P.345)
■ When the outside temperature
exceeds 75°F (24°C) and the air
conditioning system is on
● In order to reduce the air condi-
tioning power consumption, the air
conditioning system may switch to
recirculated air mode automati-
cally. This may also reduce fuel
consumption.
● Recirculated air mode is selected
as a default mode when the power
switch is turned to ON.
● It is possible to switch to outside
air mode at any time by pressing
the outside air mode switch.
■ 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.
● The windows may fog up if the
recirculated air mode is used.
■ When driving on dusty roads
Close all windows. If dust thrown up
by the vehicle is still drawn into the
vehicle after closing the windows, it
is recommended that the air intake
mode be set to outside air mode and
the fan speed to any setting except
off.
■ Outside/recirculated air mode
● Setting to the recirculated air
mode temporarily is recom-
mended in preventing dirty air
from entering the vehicle interior
and helping to cool the vehicle
when the outside air temperature
is high.
● Outside/recirculated air mode may
automatically switch depending on
the temperature setting or the
inside temperature.

■ 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 selected, 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 restricted 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.316)
• 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.
■ Ventilation and air conditioning
odors
● To let fresh air in, set the air condi-
tioning 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.
● To reduce potential odors from
occurring:
