3425-1. Using the air conditioning system
■Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the wind-
shield effectively.
● If you turn off, the windows may fog up more easily.
● The windows may fog up if the recirculated air mode is used.
■ When driving on dusty roads
Close all windows. If dust thrown up by the vehicle is still drawn into the vehi-
cle after closing the windows, it is recommended that the air i ntake mode be
set to outside air mode and the fan speed to any setting except off.
■ Outside/recirculated air mode
Setting to the recirculated air mode temporarily is recommended in prevent-
ing dirty air from entering the vehicle interior and helping to cool the vehicle
when the outside air temperature is high.
■ When the outside temperature exceeds 75 F (24 C) and air conditioning
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 in the “ON” position (vehicles without a smart key system) o r IGNITION
ON mode (vehicles with a smart key system).
● It is possible to switch to outside air mode at any time by pre ssing .
■ When the outside tempera ture falls to nearly 32F (0 C)
The dehumidification function may not operate even when is pre ssed.
■ Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning system to the out side air mode.
● During use, various odors from inside and outside the vehicle m ay enter into
and accumulate in the air conditioning system. This may then ca use odor to
be emitted from the vents.
● To reduce potential odors from occurring:
It is recommended that the air conditioning system be set to ou tside air
mode prior to turning the vehicle off.
