climate settings CHEVROLET IMPALA 2007 9.G Owners Manual

Using these settings together for long periods of
time may cause the air inside of your vehicle
to become too dry. To prevent this from
happening, after the air inside of your vehicle has
cooled, turn the recirculation mode off.
The air conditioning system removes moisture
from the air, so you may sometimes notice a small
amount of water dripping underneath your
vehicle while idling or after turning off the engine.
This is normal.
Defogging and Defrosting
Fog on the inside of the windows is a result of
high humidity (moisture) condensing on the
cool window glass. This can be minimized if the
climate control system is used properly. There are
two modes to clear fog or frost from your
windshield. Use the defog mode to clear the
windows of fog or moisture and warm the
passengers. Use the defrost mode to remove fog
or frost from the windshield more quickly.Do not drive the vehicle until all the windows
are clear.
Turn the right knob clockwise to select the defog
or defrost mode.
-(Defog):This mode directs air equally to the
windshield and the oor outlets. When defog
is selected, the system turns off recirculation and
runs the air conditioning compressor unless
the outside temperature is below 40°F (4°C).
0(Defrost):This mode directs most of the air to
the windshield with some air to the side window
vents and the oor vents. When defrost is selected,
the system will automatically force outside air into
the vehicle. The air conditioning compressor will run
automatically in this setting, unless the outside
temperature is below 40°F (4°C).
