5-2. Using the air conditioning system and defogger
■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 th e outlets and defog the windshield effec-
tively.
●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 tunn els 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 vehicl e 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.
■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
system may switch to recirculated air mode automatically. This may also reduce
fuel consumption.
●Recirculated air mode is selected as a default mode when the engine switch is
turned on.
●It is possible to switch to outside air mode at any time by pressing .
■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 dehumidification function is off, and the fan is operating, turning automatic
mode on will activate the dehumidification function.
