Audio System(s)
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, Delphi 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.
Your audio system has been designed to operate easily
and to 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 audio system can do and how to
operate all of its controls to be sure you’re getting the
most out of the advanced engineering that went into it.
Your vehicle may have a feature called Retained
Accessory Power (RAP). With RAP, you can play
your audio system even after the ignition is turned
off.
See “Retained Accessory Power (RAP)” under
Ignition Positions on page 2- 79.

radio. It works by using a secret code to disable all radio
functions whenever battery power is interrupted.
The THEFTLOCK@ feature for the radio may be used or
ignored.
If ignored, the system plays normally and the
radio is not protected by the feature.
If THEFTLOCK@ is
activated, your radio will not operate
if stolen.
When THEFTLOCK@ is activated, the radio will display

power has been interrupted.
If your battery loses power
for any reason, you must unlock the radio with the
