Turning the EATC on
Press AUTOMATIC, any of the
override controls or the fan speed
control. The EATC will only operate
when the ignition is in the ON
position.
Turning the EATC off
Press OFF. The Outside
Temperature function will continue
to operate until the ignition is
turned off.
Automatic operation
Press AUTOMATIC 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 thumbwheel is turned or the
steering wheel fan speed control is pressed (if equipped).
When in AUTOMATIC 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
1
⁄
2
minutes or less, the fan speed will start to increase
and the airflow location will change to the floor area.
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.
