Heater System: Description

The heater system delivers warm air to the passenger compartment if the engine is warmed up. Outside air, along or combined with inside air, is passed through and/or around the heater core and into the passenger compartment. By blending warm heated air passed through the heater core with cool outside air that by-passes the heater core, a desired temperature can be selected and maintained. The vehicles are equipped with a full-time outside air system which supplies a constant supply of fresh air to passenger compartment.
