NOTICE:
Don't put papers and other things that burn into
your ashtray. If you do, cigarettes or other
smoking materials could set them on fire,
causing damage.
Sun Visors
To block out glare, you can move the sun visors. You
can also swing them from side to side.
Auxiliary Power Jacks (If Equipped)
If your vehicle has these
power jacks, you'll find
them in the ashtray.These jacks provide 12
-volt power so you can operate
things such as a citizen's band (CB) radio or a cellular
phone. You'll see positive (red) and negative (black)
outlets. They have a 20
-amp fuse that is common with
the cigarette lighter. Don't use the cigarette lighter when
you're using a power jack because it may overload the
circuit and blow the fuse.
NOTICE:
Whether or not your vehicle has the power
outlets, don't plug in FM communications gear at
the ashtray area. FM equipment creates high
heat, and over time the area could get so hot that
wires could be damaged or a fire could even
break out.

Understanding Radio Reception
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 storms and power lines. Try
reducing the treble to reduce this noise if you ever get it.
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.

3-11 Tips About Your Audio System
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:

Adjust the volume control to the lowest setting.

Increase volume slowly until you hear comfortably
and clearly.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 Electronics radio or
other systems, and even damage them. 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.
