When the outside temperature exceeds 75°F (24°C) and the air conditioning system
is on
●
In order to reduce the air conditioning power consumption, the air conditioning system
may switch to recirculated air mode automatically. This may also reduce fuel consump-
tion.
●
Recirculated air mode is selected as a default mode when the engine switch is turned
on.
●
It is possible to switch to outside air mode at any time by pressing .
■
Automatic mode for air intake control
In automatic mode, the system detects exhaust gas and other pollutants and automati-
cally switches between outside air and recirculated air modes.
When the dehumidification function is off, and the fan is operating, turning automatic
mode on will activate the dehumidification function.
■
Operation of the air conditioning system in Eco drive mode
In the Eco drive mode, the air conditioning system is controlled as follows to prioritize
fuel efficiency:
●
Engine speed and compressor operation controlled to restrict heating/cooling capac-
ity
●
Fan speed restricted when automatic mode is selected
To improve air conditioning performance, perform the following operations:
●
Turn off eco air conditioning mode
●
Adjust the fan speed
●
Turn off Eco drive mode (

Eco air conditioning mode
When Eco drive mode is selected using the drive mode select switch, eco air condition-
ing mode turns on.
When a drive mode other than Eco drive mode is selected, eco air conditioning mode
may turn off.
■
When the S-FLOW mode operates
If air flows to the driver’s seat only, the temperature setting for the front passenger’s seat
is not displayed.
■
When the outside temperature is low
The dehumidification function may not operate even when “A/C” on the option control
screen is selected.
■
Ventilation and air conditioning odors
●
To let 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 accu-
mulate in the air conditioning system. This may then cause odor to be emitted from the
vents.
●
To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air mode prior
to turning the vehicle off.
• 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.
