Automatic mode for air intake control
In automatic mode, the system detects ex haust gas and other pollutants and auto-
matically switches between outside air and recirculated air modes.
When the air conditioning is off, and the fan is operating, turning the “AUTO” mode
on will activate the air conditioning system. ■
When outside temperature approaches 32°F (0°C)
The air conditioning system may not operate even when “A/C” is touched. ■
Micro dust and pollen filter ●
In order to prevent the windows from fogging up when the outside air is cold,
the following may occur.
• Outside air mode does not swit ch to recirculated air mode.
• The air conditioning system operates automatically.
• The operation cancels after 1 minute. ●
In rainy weather, the windows may fog up. Press .■
Ventilation and air conditioning odors ●
To let fresh air in, set the air conditio ning 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:
• It is recommended that the air conditio ning 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 “AUTO” mode.■
