Air Conditioning; Heating; Defogging And Defrosting - Chevrolet 2000 Lumina Owner's Manual

Air Conditioning

On very hot days, open the windows long enough to let
hot, inside air escape. This reduces the A/C compressor
load, which should help fuel economy.
-
For quick cool down on very hot days, use MAX with
the temperature control all the way in the blue area. If
this setting is used for long periods of time, the air in
your vehicle may become too dry.
For normal cooling on hot days, use A/C with the
temperature control in the blue area. The system will
bring in outside air and cool it.
On cool but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.
-
You can use BI LEVEL with the temperature control
in the middle. The system will bring in outside air
and direct it to your upper body, while sending slightly
warmed air to your lower body. You may notice
this temperature difference more at some times than
at others.

Heating

On cold days use FLOOR with the temperature control
all the way in the red area. The system will bring in
outside air, heat it and send it to the floor ducts.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it's
0 _ F ( 18 _ C) or lower. An engine coolant

heater warms the coolant your engine and heating
system use to provide heat. See "Engine Coolant
Heater" in the Index.

Defogging and Defrosting

Your system has two settings for clearing the front and
side windows. To defrost the windows quickly, use
DEFROST with the temperature knob all the way in the
red area. To warm passengers while keeping the
windows clean, use DEFOG.
