Bi Level Operation; Air-Conditioner Operating Tips; Four Season System And Comfort Ron Conditioned Outlets - Chevrolet Impala 1969 Owner's Manual

Bi Level Operation
On cool but sunny days the Comfor-
tron system will provide warm air to
the floor and cooler air out of the upper
outlets thus providing a warm floor
without excessive rise in breath level
temperature. Under extremely bright
sun conditions, the system may shift
into bi-Ievel operation at relatively
low outside temperatures in order to
maintain the temperature set on the
dial. If cool air from upper outlets is
objectionable, adjust upper outlets as
desired.
For rear seat comfort-While still pro-
viding automatic in-car temperature
control, setting the lever to REAR will
allow only the highest blower speeds
to provide continuous rapid air circu-
lation for improved rear seat pas-
senger comfort.
Four Season System and
Comfort ron Conditioned
Air' Outlets
The twin barrel type center outlet
may be rotated or vanes turned to di-
rect air flow in direction desired. The
four position lever controls the vol-
ume of air through the center outlet.
The vertical outlets at each end of
the instrument panel may be rotated
or vanes adjusted as desired.
For additional airflow lap coolers
(2) are provided under the steering
column and glove box. They have
vertical air control vane outlets and
are aimed at the driver and passenger
lap locations. Under each lap cooler is
a floor cooler outlet that is operated
in a push-pull manner for opening and
closing, controlling the amount of air
to the floor.
For window defogging - Move the
lever to DEFOG to divert a portion of
the conditioned air through the de-
froster ducts when interior window
fogging is encountered.
For windshield de-icing - With the
lever in the DE-ICE position the sys-
tem directs the entire airflow , a t full
heat and high blower speed through
the defroster ducts.
Air-Conditioner Operating Tips
Close all windows and vents when
operating air system except for the
first few minutes of operation when
the car interior is very hot. Close the
windows as soon as the excessively
heated air has escaped.
