Interior features
■Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and the
ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow immedi-
ately after the “AUTO” button is pressed or “AUTO” is selected.
■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 “START STOP
ENGINE” <“POWER”> switch is turned to IGNITION ON mode.
●It is possible to switch to outside air mode at any time by pressing .
■Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high. Selecting
“A/C” on the option control screen 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.
■Windshield fog detection function (if equipped)
When automatic mode is set, the humidity sensor (→P. 476) detects fog on the
windshield and controls the air conditioning system to prevent fog.
■Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set to
the recirculated air mode. This is effective in preventing outside air from entering
the vehicle interior. During cooling operation, setting 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 is low
The dehumidification function may not operate even when “A/C” on the option con-
trol screen is selected.
