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.
