The windows may fog up if the recirculated air mode is used.

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.
●
Outside/recirculated air mode may automatically switch depending on the tem-
perature setting or the inside temperature.
A sensor, which detects humidity inside the
vehicle and the temperature of the wind-

make the following controls:
●

Changing the amount of air introduced from
outside when in outside air mode with the air
vents in the position
