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.
When driving on dusty roads
Close all windows. If dust thrown up by the vehicle is still drawn into the vehicle after closing the windows, it is recommended that the air intake 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 preventing dirty air from entering the vehicle interior and helping to cool the vehicle when the outside air temperature is high.
- Outside/recirculated air mode may automatically switch depending on the temperature setting or the inside temperature.
When the outside temperature falls to nearly 32°F (0°C)
The dehumidification function may not operate even when “A/C” switch is pressed.
Ventilation and air conditioning odors
- To let fresh air in, set the air conditioning system to the outside air mode.
