Using the automatic mode

Fan speed is adjusted automatically in accordance with the temperature set-
ting and ambient conditions. As a result, the following may occur:

Immediately after the "AUTO" button is pressed, the fan may stop for a
while until warm or cool air is ready to flow.

Cool air may flow to the area around the upper body when the heater is on.


Fogging up of the windows


The windows will easily fog up when the humidity in the vehicle is high.
Selecting "A/C" on the operation screen on will dehumidify the air from the
outlets and defog the windshield effectively.

If you "A/C" off, the windows may fog up more easily.

The windows may fog up if the recirculated air mode is used.
