Section 3 Comfort Controls and Audio Systems
In this section you’ll find out how to operate the comfort
control and audio systems offered
with your vehicle. Be
sure
to read about the particular systems supplied with
your vehicle.
Comfort Controls
Standard Climate Control System
Fan Knob
The knob on the left side of the heating system control
panel controls the fan speed.
The knob has four speed
positions. To increase airflow, move
the knob toward
HI. To decrease airtlow, move it toward LO. To turn the
fan
off, move the knob to OFF.
Temperature Knob
The middle knob on the control panel lets you select the
relative temperature
of the air flowing into the passenger

Air Conditioning
On hot days, open the windows long enough to let hot
air inside escape. This reduces the time it takes for your
vehicle
to cool down. Then keep your windows closed
for
the air conditioner to work it’s best.
The recirculation button, between the fan and
temperature knobs, allows the air inside your vehicle to
be recirculated. This setting helps
to maximize your air
conditioner’s performance and your vehicle’s fuel
economy. This setting also
cools the air the fastest and
can be used
to keep unwanted odors and/or dust from
entering the vehicle. When using the air conditioner,
turn off recirculation after the vehicle reaches a
comfortable interior temperature. When the right knob
on the control panel is between HEATER and
DEFROST, the recirculation feature will
not function.
ProCarManuals.com

The A/C button, between the temperature and mode
knobs, allows
the air coming into your vehicle to be
cooled. This setting
is useful for normal cooling on hot
days. When
you use A/C with the recirculation button
pushed
in, turn off recirculation as soon as the vehicle
reaches a comfortable interior temperature.
With the
A/C on, move the temperature knob to MAX
for maximum cooling.
This setting also puts the system
in the recirculation mode and helps
to maximize your air
conditioner’s performance and your vehicle’s fuel
economy. This setting also cools the air the fastest. After
the vehicle’s interior reaches a comfortable temperature,
move the temperature knob clockwise to place the air
conditioning system
in the normal mode.
Heating
The heater works best if you keep your windows closed
while using
it. On cold days, use the HEATER or
VENT/HEAT setting with the temperature knob in the
red area.
If you use the engine coolant heater before starting your
engine (in cold weather (20°F (-8°C) or lower), your
heating system
will produce warmer air faster, to heat
the passenger compartment
in cold weather. The
use
of an engine coolant heater also reduces the
time
it takes for the engine to reach normal operating
temperature, and shortens the time
it takes the heater to
reach full output. For more information, see “Engine
Coolant Heater”
in the Index.
Ventilation System
For mild outside temperature when little heating or
cooling
is needed, use VENT to direct outside air
through
your vehicle. Air will flow through the
instrument panel outlets.
Your vehicle’s ventilation systeril supplies outside air
to the inside of your vehicle when it is moving. With
the side windows closed, air will flow into the front
air inlet grilles, through the vehicle, and out the air
exhaust valves.
Outside air will
also enter the vehicle when the heater or
the air conditioning fan is running, unless you have
the
recirculation button pushed in. For more information on
the recirculation button, see “Air Conditioning” earlier
in this section.

Ventilation Tips
Your vehicle has air outlets in the center and on the sides
of your instrument panel. You can move the outlets from
side to side or up and down to direct the
flow of air, or
close the outlets altogether. When
you close an outlet, it
will increase the flow of air coming out of any outlets
that are open. These outlets do not completely
shut off
airflow when
in the closed position.

Keep the hood and front air inlet free of ice, snow or
any other obstruction (such
as leaves). The heater
and defroster
will work far better, reducing the
chance of fogging the inside
of your windows.
When you enter
a vehicle in cold weather, turn the
blower fan to HI for a few moments before driving.
This helps clear the intake ducts
of snow and
moisture, and reduces the chance
of fogging the
inside
of your windows.
Keep the air path under the front seats clear
of
objects. This helps air to circulate throughout
your vehicle.
Defogging and Defrosting
On cool, humid days, use DEFOG to keep the
windshield and side windows clear.
Use DEFROST
to remove fog or ice from the windshield in extremely
humid or cold conditions. Use DEFROST
with the
temperature knob toward
the red area and the fan control
toward
HI.

Rear Window Defogger (Option)
If you see lines running across the rear window,
you have the rear window defogger. The lines warm
the glass.
- To turn on the rear window
defogger, press this button next
to the fan control knob.
The rear window defogger
will only work
if the
ignition switch
is turned to
RUN. For best results, clear
the window of as much
snow or ice as possible first.
The defogger will shut itself
off after several minutes. If
you need additional warming time, press the button
again.
You can turn the defogger off at any time by
pressing the button. Do not
attach a temporary vehicle license, tape
or decals
across the defogger grid
on the rear window.
LOTICE:
Don’t use a razor blade or something else sharp
on the inside
of the rear window. If you do, you
could cut or damage the warming grid, and the
repairs wouldn’t be covered by your warranty.
Audio Systems
Your Delco@ audio system has been designed to operate
easily and give years of listening pleasure.
You will get
the most enjoyment out of
it if you acquaint yourself
with
it first. Find out what your Delco system can do
and how to operate all its controls, to be sure you’re
getting the most
out of the advanced engineering that
went into
it.
