3385-1. Using the air conditioning system and defogger
SIENNA_OM_OM08019U_(U)
■Using automatic mode
Fan speed is adjusted automatically according to the temperatur e setting and
the ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow
immediately after the “AUTO” button is pressed.
■ When the outside temperature exceeds 75°F (24°C) and the air co ndition-
ing system is on
● In order to reduce the air conditioning power consumption, the air condition-
ing 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 en gine switch
is turned to the “ON” position (vehicles without a smart key sy stem) or
IGNITION ON mode (vehicles with a smart key system).
● It is possible to switch to outside air mode at any time by pre ssing .
■ Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high.
Pressing “A/C” button on will dehumidify the air from the outle ts 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
to the recirculated air mode. This is effective in preventing outside air from
entering the vehicle interior. During cooling operation, setting the recircu-
lated air mode will also cool the vehicle interior effectively.
● Outside/recirculated air mode may automatically switch dependin g on the
temperature setting or the inside temperature.
