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 A/C: This setting cools the outside air. If you first used MAX A/C,
use NORM A/C as soon as the vehicle has cooled down, so outside air will
be going through your vehicle.
MAX A/C: 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
A/C at first when it's really hot outside and you need to cool off quickly.
When the air conditioning, defrost or Blend is on, you
may notice a slight
increase or decrease
in engine speed, due to compressor operation.
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 located
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 you use the optional engine coolant heater before starting your engine,
your heating system will produce warmer air faster to heat the passenger
compartment in cold weather. See “Engine Coolant Heater” in the Index.
Audio Systems
Your Delco@ 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 most out
of
the advanced engineering that went into it.
Be aware that 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 your
hearing adapts to it.
To help avoid hearing loss or damage:
0 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 reach 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.
The range for most AM stations is greater than for FM, especially 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 broadcasts.
Many AM stations around the country use C-QUAM@ to produce stereo,
though some do not. (C-QUAM@ is
a registered trademark of Motorola,
Inc.) If your Delco@ system can get C-QUAM@, your
“STEREO” light will
come on
when you’re receiving it.
