How to Use the System
This section covers how to set up the
system controls for ventilation,
heating, cooling, dehumidifying, and
defrosting.
The engine must be running for the
heater and air conditioning to
generate hot and cold air. The heater
uses engine coolant to warm the air.
If the engine is cold, it will be several
minutes before you feel warm air
coming from the system.
The air conditioning does not rely on
engine temperature.
