Programmed Defrost
The programmed defrost function is only available on vehicles fitted with a dual zone heating, ventilation and A/C system. The function is selected by pressing the 'PROG' momentary switch on the control panel. When selected, the ATC module provides maximum windshield defrosting/demisting by configuring the system as follows:
- 'AUTO' mode off
- Intake air set to fresh air
- Air distribution set to windshield
- Blower motor speed set to maximum
- Heated windshield on
- Rear window heater on.
When programmed defrost is selected, the set temperature will remain unchanged. Programmed defrost can be cancelled by any of the following methods:
- Pressing any air distribution momentary switch
- Pressing the 'AUTO' switch located in the center of the blower motor rotary controller
- Pressing the 'PROG' momentary switch a second time.
NOTE:
Blower motor speed can be adjusted without terminating programmed defrost.
