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.

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 off,
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 for the
heating and cooling system are at
the base of the windshield. Keep
these clear of leaves and other
debris.
Ventilation
The flow-through ventilation system
draws in outside air, circulates it
through
the interior, then exhausts it
through vents behind
the seat-backs.
Heating and Cooling
1. Turn the temperature control dial
all
the way to the left.
Make sure
theA/Cis off.
2. Select ;J and Fresh Air mode.
3. Set the fan to the desired speed.

AIR .coNDitiONING ·~-+-::-:

These settings direct all the air flow
to the defroster vents at the base of
the windshield and the side window
defroster vents.
The air flow will get
warmer and clear the windows faster
as the engine warms up. You can
close the side vents with the dial
beside each vent.
This will send
more warm air to the windshield
defroster vents.
For safety, make sure you have a
clear view through all the windows
before driving away.
To Tum Everything Off
To shut off the system temporarily,
turn off the fan (no lights
illuminated).
You should shut the system
completely off only for the first few
minutes of driving in cold weather,
until the engine coolant warms up
enough to operate the heater. Keep
the fan on at
all other times so stale
air does not build up
in the interior.
