Heater System: Operation: Notes

Heater and fresh air operations are controlled by 4 different control levers. The control panel consists of a mode control lever for inside/outside air, temperature control, air selector and a multi-speed blower switch. The temperature control opens and closes a heater control valve which determines heat output.

The heater mode control directs heated air to the windshield when in "DEF" position, to the floor when in "HEAT" position, or to the center ventilation ducts when in "VENT". Bi-level output is possible by positioning the lever between "VENT" and "HEAT".

The rear heater on Montero models blows warm both forward and backward. This provides a properly distributed air flow rate to provide comfortable heating. The rear heater switch, located under the center of the rear seat, has a single lever which serves the combined purposes of the heater fan switch and heater control lever.
