PO450
If your vehicle does not have air conditioning, this is what your heating
system will
look like.
Fan Lever
The top lever has five positions. To increase the air flow, move the lever
toward
HIGH. To decrease the air flow, move it toward OFF.
Temperature Lever
The left lever lets you select the temperature of the air flowing into your
vehicle. Move the lever up for warmer air. Move the lever dow\
n for cooler air.
Function Lever
The right lever can be moved to four different functions.
Defrost: The setting with the defrost symbol operates the defroster. Mos\
t of
the air comes out near the windshield, with some going to the floor vents.
Use this when you get fog or ice on the windshield.
HTR (Heater): Most of the air comes out near the floor. The rest comes out
from the defroster vents under the windshield and at the front side windows.
This is best for cold weather.
VENT: The air comes out at the vents on your instrument panel and \
at your
front side windows.
BLEND: With this setting, the heated outside air comes out between the
heater vents and defroster vents with some air coming through \
the side
vents. Adjust the temperature lever for warmer or cooler air.

side windows.
This is best for cold weather.
VENT The air comes out at the vents on your instrument panel and at your
front side windows. The air conditioner will not run. Adjust t\
he temperature
lever for warmer or cooler air.
BI-LEV NC: With this, outside air comes in through the heater floor vent and
the instrument panel vents.
If you move your temperature control lever
between cold and hot, cooler air will come out of the upper vents while
warmer air comes out of the
floor vent. This setting is useful in cool weather
with bright sunlight.
NORM NC: This setting cools the outside air. If you first used MAX NC, use
NORM NC as soon as the vehicle has cooled down, so outside air will be
going through your vehicle.
MAX NC: This cools the air the fastest. Move the other lever all the \
way to
Cold.
MAX A/C lets in only a little air from the outside. You can use MAX
NC at first when it’s really hot outside and you need to cool off quickly.
When the air conditioning or defrost is on, you may notice a slight increase
or decrease in engine .speed.
Rear Heater
You may have the optional rear heater. The three-speed fan switch is above
the radio. Slide the lever toward
HI for warmer air in the rear area. Move the
switch to
OFF to turn the system off.

Rear Air Conditioning
You may have rear air conditioning. The rear air conditioning switch is loca\
ted
above the radio at the top of the instrument panel. Slide the lever toward
HI
for cooler air in the rear area. Slide the lever to OFF to turn the system off.
If your vehicle has rear air conditioning, setting it on LOW may enhance front
NC performance by allowing trapped refrigerant in rear lines to circulate.
The system
will only send cooled air if the front system is on. It can still be
used
to recirculate air, even if the front system is off.
Before using the rear air conditioning, open the windows to cl\
ear the vehicle
of hot air. Close the windows when using the system.
Rear Window Defogger
HATCH REL REAR DEFOG
If your vehicle has this option the rear window will have lines \
running across
the glass. These lines heat your window.
For best results, clear the window of as much snow and ice as possible
before using the rear window defogger.
To turn on the rear window defogger, find the switch marked
Rear Defog on
your instrument panel to the left of the steering column. Press the top of the
switch until the light in the switch comes on, then release it. The rear window
defogger will only work when the ignition is in the
RUN position.
You can turn the defogger
off at any time by pressing the bottom of the
switch. The defogger will shut itself
off after several minutes so that the glass

again.
Scraping the inside of your rear window could cut and damage th-
defogger. Your warranty would not cover this damage.

decals there, you might have to scrape them

Engine Block Heater
If you use the optional engine block heater before starting yo\
ur engine, your
heating system will produce warmer air faster to heat the pass\
enger
compartment in cold weather. See “Engine Block Heater” in the Index.
Audio Systems
Your Dekoa audio system has been designed to operate easily and give
years of listening pleasure. But 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 mos\
t out of
the advanced engineering that went into it.
CAUTION
Hearing damage from loud noise is almost undetectable until it is too
late. Your hearing can adapt to higher volumes
of sound. Sound that
seems normal can be loud and harmful to your hearing. Take
’ precautions by adjusting the volume control on your radio to a safe
sound level before hearing adapts to it.
To help avoid hearing loss or damage:
Adjust the volume control to the lowest setting.
Increase volume slowly until you hear comfortably and clearly.

FM Stereo
FM stereo will give you the best sound. But FM signals will reac\
h only about
10 to 40 miles (16 to 65 km). Tall buildings or hills can interfere with FM
signals, causing the sound to come and go.
AM
The range for most AM stations is greater than for FM, especi\
ally at night.
The longer range, however, can cause stations to interfere with\
each other.
AM can pick up noise from things like storms and power lines. Try reducing
the treble to reduce this noise
if you ever get it.
AM Stereo
This means the Delco@ system can receive C-QUAM@ stereo broadca\
sts.
Many AM stations around the country use
C-QUAM@ to produce stereo,
though some do not.
(C-QUAM@ is a re istered trademark of Motorola, Inc.)
If your Delco@ system can get C-QUAM’, 8 your “STEREO” light will come on
when you’re receiving it.
