How to Use the System
This section covers the best way
to use the system for ventilation,
cooling, dehumidifying, defrosting
and heating. In most cases, the
mode and air source selections
are only recommendations. You
may prefer different settings.
Use mode to heat or cool
the interior more quickly, or to
keep out smoke and dust. Leaving
the system in recirculation mode
with the air conditioning off can
cause the windows to fog up.
Switch to mode as soon as
the interior reaches a
comfortable temperature or the
outside smoky, dusty condition
clears.
The engine must be running for
the heater and air conditioning
system to provide 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
circulating.
Air conditioning does not depend
on engine temperature. It can
produce cold air almost
immediately.
Controlling Air Flow Direction
Air flows into the interior at three
levels: Toward the floor
through the dash vents
and toward the windshield and
side windows You select
the air flow level or combination
of levels with the five mode
buttons.
Heating and Cooling
Ventilation
Your car has a flow-through
ventilation system. Air enters the
car through vents in front of the
windshield. It circulates through
the interior and then exits
through vents near the rear
window. This system provides
fresh air even when the car is
standing still. To bring in outside
air, press the
the fan at a comfortable speed.
