Rear Window Defogger
You can tell if your vehicle has this option by looking at the rear window. If
you see lines running across the glass, you have it. These are the wire-like
elements which heat your window.
1 NOTICE:
Scraping the inside of your rear window could cut and damage
the defogger. Your warranty would
not cover this damage. And,
don't
put decals there, you might have to scrape them off.
For best results, clear the window of as much snow or ice as possible first.
To turn on the rear
window defogger, find
the switch marked
REAR DEFOG on
your instrument panel,
just below the heater
system.
Press the right side of
the switch, with the defog symbol on it, until the light
in the switch comes on, then release it.
The rear window defogger will only work if the ignition switch is turned to
RUN.
You can turn the defogger off at any time by pressing the left, lighted side of
the switch. The defogger will
shut itself off after several minutes, so that the
glass does not get too hot. If the defogger shuts off, and the window still
isn't clear, turn the defogger
on again.

A udia 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.
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.
0 Increase volume slowly until you hear comfortably and clearly.
FM Stereo
FM stereo will give you the best sound. But FM signals can only reach
about 10 to
40 miles (16 to 65 km). And, 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, especially at night.
The longer range, however, can cause stations to interfere with each other.
AM can pick up noise from things like electrical storms and power lines.
If
the noise interferes with your listening, try reducing the treble to lessen the
noise.
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. If your Delco@ system can get C-QUAM@, your
“STEREO” light will come on when you’re receiving it. (C-QUAM@ is a
registered trademark of Motorola, Inc.).

NOTICE:
Before you add any sound equipment to your vehicle - like a
tape player,
CB radio, mobile telephone or two-way radio - be
sure you can add what you want.
If you can, it’s very important
to do it properly. Added sound equipment may interfere with the
operation of your vehicle’s engine, Delco@ radio or other
systems, and even damage them. And, your vehicle’s systems
may interfere with the operation
of sound equipment that has
been added improperly.
So, before adding sound equipment, check with your dealer and
be sure to check Federal rules covering mobile radio and
telephone units.
