Chevrolet STFF7S Automobile User Manual


 
BLEND
-
With this setting, the heated outside air comes out both the
heater
vents
and defroster vents,
with
some air coming through the side
window vents. Adjust the temperature lever
for
warmer
or
cooler air. This
setting
is
useful for cold weather with a large number of passengers
or
very
humid conditions
to
help keep the windshield clear. The A/C compressor
may operate in this setting
to
dehumidify the air.
HTR (Heater)
-
Most of the air comes
out
near
the
floor. The rest comes
out
from the defroster vents under the windshield and at the front side
windows. This
is
best for cold weather.
VENT
-
The air comes out at
the
vents
on
your instrument panel. The air
conditioner will not run. Adjust the temperature lever for warmer or cooler air.
BI-LEV
A/C
-
With this, outside air comes out through the heater floor
vent and the instrument panel vents. If you move your temperature control
lever between cold and hot, cooler air
will
come
out
of
the
upper vents
while warmer air comes
out
of
the
floor vent. This setting is useful
in
cool
weather with bright sunlight.
NORM
A/C
-
This setting cools the outside air. If you first used MAX
A/C, use NORM A/C
as
soon as
the
vehicle has cooled down,
so
outside air
will be going through your vehicle.
MAX A/C -This cools the air the fastest. Move
the
other lever all the way
to
Cold. MAX A/C lets
in
only
a
little air from the outside. You can use MAX A/C
at first when
it's
really
hot
outside and you need to cool off quickly.
When
the
air conditioning, defrost or BLEND is
on,
you
may notice a slight
increase or decrease in engine speed, due
to
compressor operation.
Engine Coolant Heater (Option)
If you use the optional engine coolant heater before starting your engine,
your heating system will produce warmer air faster to heat the passenger
compartment
in
cold weather. See "Engine Coolant Heater"
in
the Index.
Rear Heater (Option)
You
may have the
optional rear heater.
The three speed fan
switch is above the
radio. Slide
the
lever
toward
HI
for warmer
air in the rear area.
Move the switch to
OFF
to turn
the
system off.
