Climate Controls
Turning the EATC on

EATC will only operate when the vehicle is running.
Turning the EATC system off
Press OFF.
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 outside air or recirculated air is required.
When in AUTO and weather conditions require heat, the EATC system
directs the majority of the airflow to the floor area. The system will allow
some airflow through the windshield defroster ducts to reduce window
fogging. However, if the engine is not warm enough to provide heat, the
fan will be at a low speed and the airflow will be directed to the
windshield. In approximately 3 1 ⁄ minutes or less, the fan speed will start
2
to increase and the airflow location will change to the floor.
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.
