Audio System(s)
Notice:Before adding any sound equipment to
your vehicle, like a tape player, CB radio, mobile
telephone, or two-way radio, make sure that it can
be added by checking with your dealer. Also,
check federal rules covering mobile radio and
telephone units. If sound equipment can be added,
it is very important to do it properly. Added
sound equipment may interfere with the operation
of your vehicle’s engine, 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.
Figure out which audio system is in your vehicle, nd
out what your audio system can do, and how to operate
all of its controls.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, the audio system can be
played even after the ignition is turned off. SeeRetained
Accessory Power (RAP) on page 2-19for more
information.
Setting the Time

represent hours and an M or MN to represent minutes.
Press and hold the hour button until the correct hour
appears on the display. AM or PM will appear on
the display for morning or evening hours. Press and
hold the minute button until the correct minute appears
on the display. The time can be set with the ignition
on or off.

Radio Data System (RDS)
The audio system has a Radio Data System (RDS).
RDS features are available for use only on FM stations
that broadcast RDS information.
With RDS, the 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
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 the radio is tuned to an RDS station, the station
name or 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.
