B730A01L-AATOperation Tipso To keep dust or unpleasant fumes from
entering the car through the ventilation
system, temporarily set the air intake
control at the position. Be sure to
return the control to the position
when the irritation has passed to keep
fresh air in the vehicle. This will help
keep the driver alert and comfortable.
o Air for the heating/cooling system is
drawn in through the grilles just ahead
of the windshield. Care should be taken
that these are not blocked by leaves,
snow, ice or other obstructions.
o To prevent interior fog on the wind-
shield, set the air intake control to the
fresh air ( ) position and fan speed to
the desired position, turn on the air
conditioning system, and adjust
temperature control to desired tempera-
ture.

B740C02O-AATDe-Humidified HeatingFor dehumidified heating:
o Set the air flow control to the face ( )
position.
o Turn on the air conditioning switch. The
air conditioning indicator light should
come on at the same time.
o Set the air intake control to the fresh air
( ) position.
o Adjust the fan control to the desired
speed.
o For more rapid action, set the fan at one
of the higher speeds.
o Adjust the temperature control to provide
the desired amount of warmth.
B740D02Y-AATOperation Tipso If the interior of the car is hot when you
first get in, open the windows for a few
minutes to expel the hot air.
o When you are using the air conditioning
system, keep all windows closed to
keep hot air out.
o When moving slowly, as in heavy traffic,
shift to a lower gear. This increases
engine speed, which in turn increases
the speed of the air conditioning
compressor.
o On steep grades, turn the air condition-
ing off to avoid the possibility of the
engine overheating.
o During winter months or in periods when
the air conditioning is not used regularly,
run the air conditioning once every
month for a few minutes. This will help
circulate the lubricants and keep your
system in peak operating condition.
