this section.
Understanding Radio Reception
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.
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.
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 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.

Downloaded from www.Manualslib.com manuals search engine Battery
Every new vehicle has a Delco Freedom@ battery. You
never have to add water to one of these. When it’s time
for a new battery, we recommend a Delco Freedom
battery. Get one that has
the replacement number shown
on the original battery’s label.
Vehicle Storage
If you’re not going to drive your vehicle for 25 days
or more, take off the black, negative
(-) cable from
the battery. This will help keep your battery from
running down. Also,
for your audio system, see “Theft-Deterrent
Feature” in the Index.
Bulb Replacement
For any bulb changing procedure not listed in this
section, contact your
GM dealer service department.
Before replacing any bulbs, make sure all lamps are
off
and the vehicle is not running. See “Replacement Bulbs”
in the Index.
Halogen Bulbs
Batteries have acid that can burn you and gas
that can explode.
You can be badly hurt if you
aren’t careful. See “Jump Starting” in the Index
for tips on working around a battery without getting hurt.
Contact your dealer to learn how
to prepare your vehicle
for longer storage periods.
I A CAUTION:
I
Halogen bulbs have pressurized gas inside and
can burst if you drop or scratch the bulb.
You or
others could be injured. Be sure to read and
follow the instructions on the bulb package.
