 Outside/recirculated air mode
 When driving on dusty roads such as tunnels or in heavy traffic, set the out-
side/recirculated air mode button to the recirculated air mode. This is effec-
tive in preventing outside air from entering the vehicle interior. During
cooling operation, setting the recirculated air mode will also cool the vehi-
cle interior effectively.
 Outside/recirculated air mode may automatically switch depending on the
temperature setting or the inside temperature.
 When the hybrid battery cooling system operates
 If the hybrid battery cooling system operates when the air conditioning is
off, a message will be shown on the multi-information display and the air
conditioning will automatically turn on. (P. 123)
 The sound of the air flow may change when cool air flows from the rear
roof vents or the air purifier is in operation. This occurs when the hybrid
battery is being cooled and does not indicate a malfunction.
 Automatic mode for air intake control
In automatic mode, the system detects exhaust gas and other pollutants and
automatically 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.

cold, the following may occur:
• Outside air mode does not switch to (recirculated air) mode.
• The dehumidification function operates.
• The operation cancels after approximately 1 minute.
 In rainy weather, the windows may fog up. Press .
 In extremely humid weather, the windows may fog up.

 When the outside temperature falls to nearly 0C (32F)
The dehumidification function may not operate even when “A/C” on the
operation screen is selected.
