after is pressed or “AUTO” is selected.
■Using the voice command system (veh icles with a navigation system)

“Navigation System Owner’s Manual”.
■Fogging up of the windows
The windows will easily fog up when the humidity in the vehicle is high. Turning
(“A/C”) on will dehumidify the air from the outlets and defog the windshield effectively.
●If you turn (“A/C”) off, the windows may fog up more easily.
●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/recircu-
lated air mode button to the recirculated ai r 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.

ture setting or the inside temperature.
■When the outside temperature exceeds 75 F (24 C) and the air conditioning system
is on
●In order to reduce the air conditioning po wer consumption, the air conditioning system
may switch to recirculated air mode automa tically. This may also reduce fuel consump-
tion.
●Recirculated air mode is selected as a default mode when the engine switch is turned to
IGNITION ON mode.
●It is possible to switch to outside air mode at any time by pressing .
■Operation of the air conditioning system in Eco drive mode
