This section covers how to set up the
system controls f or ventilation,
heating, cooling, dehumidif ying, and
def rosting.
The engine must be running f or 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 bef ore you f eel warm air
coming from the system.
The air conditioning does not rely on
engine temperature.
It is best to leave the system in Fresh
Air mode under almost all conditions.
Keeping the system in Recirculation
mode, particularly with the A/C of f ,
can cause the windows to fog up.
Switch to Recirculation mode when
you are driving through smoky or
dusty conditions, then switch back to
Fresh Air mode when the condition
clears.The outside air intakes f or the
heating and cooling system are at
the base of the windshield. Keep
these clear of leaves and other
debris.
