(If Equipped)
Playing the Radio
PWR-VOL: Press this knob to turn the system on and
off. To increase volume, turn the knob clockwise. Turn
it counterclockwise
to decrease volume. The knob is
capable of being rotated continuously.
RECALL: Display the time with the ignition off by
pressing this button. When the radio is playing, press
this button

Set the volume at the
desired level. Move the control ring behind
the upper
knob clockwise to adjust the
SCV. Then, as you drive,
SCV automatically increases the volume, as necessary,
to overcome noise at any particular speed. The volume
level should always sound the same
to you as you drive.
If
you don't want to use SCV, turn the control all the
way down. Each detent on the control ring allows for
more volume compensation at
a faster rate of speed.

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.

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.
A CA“T1ON:
Bulb Replacement
Before you replace any bulbs, be sure that all the lamps
are off and the engine isn’t running. See “Replacement
Bulbs”
in the Index for the proper types of bulbs to use.
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.
Also, for your audio system, see “Theft-Deterrent
Feature”
in the Index.
-N:
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.
