Interior features
■Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set the outside/
recirculated air mode button to the recirculated air mode. This is effective in pre-
venting outside air from entering the vehicle interior. During cooling operation, set-
ting the recirculated air mode will also cool the vehicle interior effectively.

perature setting or the inside temperature.
■When the outside temperature exceeds 75°F (24°C) and the air conditioning sys-
tem is on
●In order to reduce the air conditioning power consumption, the air conditioning

turned on.
●It is possible to switch to outside air mode at any time by pressing .

matically switches between outside air and recirculated air modes.

■Micro dust and pollen filter
●In order to prevent the windshield from fogging up when the outside air is cold, the
following may occur:

• The dehumidification function operates.
• The operation cancels after approximately 1 minute.
●In rainy weather, the windows may fog up. Press .

seat is not displayed.
