Operation

MANUAL THREE ZONE

FRONT CONTROL PANEL

- Primary control of the rear heater-A/C system is on the instrument panel. This control allows the driver to set the rear compartment fan speed, to turn the rear heater-A/C system off, or to give control to the intermediate seat occupants by switching to the Rear position. When the rear heater-A/C system is controlled from the instrument panel, rear air temperature is based on the driver-side temperature control position, and the mode (floor or overhead air) is based on the front control's mode position.
- The mode control knob enables continuously variable proportioning of air flow between modes but has detents adjacent to each icon.
- The blower control provides four separate speeds and an Off position. When the heater-A/C system is off, the HVAC computer closes the recirculation door to prevent outside air from entering the passenger compartment.
- Interior air may be recirculated to speed up heating or cooling in all modes except defrost and mix by pressing the Recirculate button on the control panel.
- To reduce humidity for rapid defogging the A/C compressor runs automatically in modes from "mix' to full defrost when outside temperatures are above freezing.
- Air conditioning is available in any mode by pressing the snowflake, A/C on/off, button.

REAR CONTROL PANEL

With the rear control active, temperature selection dictates the air distribution mode (floor or overhead air) of the rear unit: a cool temperature setting directs flow to the overhead outlets and a warm temperature setting to the floor.
