DEATC automatic operation
When in AUTO mode, the DEATC
system automatically controls the air
conditioning operation, the fan
speed, the airflow direction and
determines whether outside or
recirculated air is required.
Press AUTO and select the desired
temperature. The selected
temperature will appear in the
display window, and an indicator
above the AUTO control will light.
The DEATC system will either heat or cool the vehicle to achieve the
selected temperature.
When in AUTO mode and the weather is cool, the DEATC directs the
majority of the airflow to the floor area. The system will allow some
airflow out the windshield defroster ducts and the demister outlets to
reduce window fogging. Additionally, if the engine is not warm enough to
provide heat, the fan will operate at a low speed and the airflow will be
directed to the windshield or to the floor. 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 as necessary. To
return to full automatic control, press the AUTO control.
