■Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set the outside/recircu- lated air mode button to the recirculated air mode. This is effective in preventing out- 
side air from entering the vehicle interior. During cooling operation, setting the recirculated air mode will also cool  the vehicle interior effectively.
●Outside/recirculated air mode may automatically switch depending on the tempera- 
ture setting or the inside temperature.
■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 performanc e, perform the following operations:
●Adjust the fan speed
●Turn off Eco drive mode (P. 311)
■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.
