Automatic operation

Press AUTO and select the desired temperature.
The selected temperature and the word AUTO will
appear in the display window. The EATC system will
either heat or cool to achieve the selected
temperature. The system will automatically
determine fan speed, airflow location and if fresh
outside air or recirculated air is required. Fan speed
remains automatic unless the fan speed control is
pressed.
When in AUTO and weather conditions require heat,
air will be sent to the floor. However, if the engine is
not warm enough to provide heat, the fan will be at
a low speed and the air will be directed to the
windshield. In 3 ⁄ minutes or less, the fan speed will

If unusual conditions exist (i.e.-window fogging,
etc.), the manual override controls allow you to
select airflow locations and the fan control allows
you to adjust fan speed as necessary.
