SYSTEM OPERATION
• Ventilation system

HEATING SYSTEM
The heating system operates with engine coolant
continuously flowing through the heater core tubes
and transferring heat to the core fins. Heat is then
exchanged with incoming air selected to flow over the
fins to warm the air.
The occupant manually selects a desired temperature
setting that determines the position of the
temperature mix door to regulate how much air flow is
permitted to pass through the heater core. The
remaining ambient air bypasses the heater core and
enters the ventilation system. The total airflow mix,
blending warm and ambient air, is sent to the
passenger compartment through the ventilation
system.
