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
rst. 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 has 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)”underIgnition

on FM stations that broadcast RDS information.Using this system, your radio can do the following:
Seek to stations broadcasting the selected type of
programming,
receive announcements concerning local and
national emergencies,
display messages from radio stations, and
seek to stations with traffic announcements.
This system relies upon receiving specic information
from these stations and will only work when the
information is available. In rare cases, a radio station
may broadcast incorrect information that will cause
the radio features to work improperly. If this happens,
contact the radio station.
While you are tuned to an RDS station, the station name
or the call letters will appear on the display, instead of the
frequency. RDS stations may also provide the time of
day, a program type (PTY) for current programming and
the name of the program being broadcast.
DISP (Display):Press this knob to change what
appears on the display while using RDS. The display
options are station name, RDS station frequency,
PTY and the name of the program (if available).
To change the default on the display, push the knob
until you see the display you want, then hold the knob
for two seconds. The radio will produce one beep
and selected display will now be the default.
