1997 BUICK REGAL air filter

Comfort Controls
Manual Single Zone Climate Control
COMFORT CONTROL II
With this system, you can control the heating, cooling
and ventilation in your vehicle, The system works best if
you keep your windows closed while using it.
Fan Knob
The left knob selects the amount of air you want. To turn
the fan off, turn the knob to
OFF.
If the airflow seems very low when the fan knob is turned
to
the highest setting, regardless of the mode setting, your
passenger compartment air filter may need to be replaced. See “Maintenance Schedule”
in the Index.
Temperature Knob
The center knob changes the temperature of the air
coming through the system. Turn this knob toward red
(clockwise) for warmer air. Turn it toward blue
(counterclockwise) for cooler air.
Mode Knob
The right knob has several settings to control the
direction of airflow:
MAX: This setting recirculates much of the air inside
your vehicle and sends it through the instrument panel
outlets. The air conditioning compressor will run
automatically
in this setting unless the outside
temperature is below
40°F (4°C). (Even when the
compressor is running,
you can control the temperature.)
NORM: This setting brings in outside air and sends
it through the instrument panel outlets. The air
conditioning compressor will run automatically in
this setting unless the outside temperature
is below
40°F (4°C). (Even when the compressor is running,
you can control the temperature.)

Heating
On cold days, use HTR with the temperature knob 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
cold outside
(0°F (- 18 O 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.
Ventilation
For mild outside temperatures when little heating or
cooling is needed, use VENT to direct outside air
through your vehicle. Your vehicle also has the
flow-through ventilation system described later in
this section.
Defogging and Defrosting
Your system has two settings for clearing the front and
side windows.
To defrost the windows quickly, use
FRONT with the temperature knob all the way in the red
area.
To warm passengers while keeping the windows
clear, use
BLEND.

With this system, the driver and passenger can maintain
separate temperatures. The system works best if you
keep your windows closed while using it.
Fan Control
The left knob labeled FAN controls the fan speed selection.
If the airflow seems very low when the fan knob is turned
to the highest setting regardless
of the mode setting, your
passenger compartment air filter may need to be replaced. See “Maintenance Schedule’’ in the Index.
Driver’s Temperature Knob
The center knob sets the temperature for the driver’s
outlets.
Turn the knob toward red (clockwise) for warmer
air. Turn it toward blue (counterclockwise) for cooler air.

FRONT and full hot
(90°F (32°C)). Driver sets
temperature and selects high fan speed.
To warm
passengers while keeping the windows clear, push the
AIR FLOW button until WINDSHTELDFLOOR
appears
in the display. Select fan speed for comfort and
windshield clearing performance. Adjust the direction
of
airflow by moving the
louvered vents.
Your vehicle’s flow-through ventilation system supplies
outside air into the vehicle when
it is moving. Outside
air will also enter the vehicle when the
air conditioning
fan is running.
If the airflow seems very low when the fan knob is
turned to the highest setting regardless of
the mode
setting, your passenger compartment air filter may need
to be replaced. See “Maintenance Schedule” in

Maintenance Schedule
Short TripKity Definition
Follow the Short TripKity Maintenance Schedule if any
one of these conditions is true for your vehicle:
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
0 Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
Most trips are through dusty areas.
0 You frequently tow a trailer or use a carrier on top of
your vehicle. (With some models, you should never
tow
a trailer. See “Towing a Trailer” in the Index.)
0 If the vehicle is used for delivery service, police, taxi
or other commercial application.
One
of the reasons you should follow this schedule if
you operate your vehicle under any of these conditions
is that these conditions cause engine oil to break
