Your audio system is equipped with a Radio Data
System (RDS). RDS mode gives you many useful new
features. With RDS, the radio can do the following:

Seek only to stations with the types of programs you
want to listen to,

seek to stations with traffic announcements,

receive announcements concerning local and
national emergencies, and

receive and display messages from radio stations.
RDS features are only available for use on FM stations
which broadcast RDS information. The RDS features of
your radio rely upon receiving specific RDS information
from these stations. These features will only work when
the RDS 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, please contact the radio station.
When you are tuned to an RDS station, the station
name will appear on the display, instead of the
frequency. Most RDS stations provide their station
name, the time of day and a Program Type (PTY) for
their current programming.

3-46 Headphones
The entertainment system includes two
IR wireless headphones.
Mini
-headphone jacks are also provided for use
with customer provided headphones.
The wireless headphones have an ON/OFF switch
and a volume control. To use the headphones turn the
switch to ON. An indicator light will illuminate. If the
light does not illuminate, the batteries may need to be
replaced. See ªBattery Replacementº later in this
section for more information. Switch the headphones
to OFF when not in use.
If the system is shut off, or if the headphones are out
of range of the IR transmitters below the overhead
RSE control panel for more than three minutes,
the headphones will shut off automatically to save the
battery. If you move too far forward or step out of the
vehicle, the headphones will lose the audio signal.
To adjust the volume on both pairs of wired headphones,
use the volume control.
NOTICE:
Do not store the headphones in heat or direct
sunlight. This could damage the headphones
and would not be covered by your warranty.
Keep the headphones stored in a cool, dry place.

1. Loosen the screw on the battery compartment
door located on the left side of the headphones.
2. Remove the batteries from the compartment.
3. Replace the two AAA batteries. Make sure that

of time, remove the batteries and keep them in a cool,
dry place.

3-47 Stereo RCA Jacks
The RCA jacks and the mini-headphone jacks are
located behind the video screen on the overhead console.
The RCA jacks allow you to hook up an auxiliary device
such as a camcorder or a video game unit. The yellow
RCA jack is used for video and the red and white RCA
jacks are used for audio. You may require adapter
connectors or cables to connect your auxiliary device to
the RCA jacks. Refer to the manufacturer's instructions
for proper usage. The mini
-headphone jacks allow you
to hook up customer provided wired headphones.
To use the auxiliary audio and video inputs on the RSE,
connect an external auxiliary device such as a camcorder
to the RCA jacks and turn on both the auxiliary device
power and the power on the front of the RSE player.
If a disc is not present in the player, the auxiliary signal
will immediately be displayed on the RSE. If a disc is
present when the RSE power is turned on, the player will
automatically begin playing the disc and the user will need
to press the AUX button on the remote control to display
and/or hear the auxiliary input signals. Each successive
press of the AUX button on the remote control will switch
the system between disc and auxiliary input. The wired

DVD player power is turned on and it controls both wired
headphone jacks at the same time. See ªRemote Controlº
