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.

Program Type (PTY) selections. PTY and the light next

-TYPE control to select the PTY
you want to listen to. Press the SEEK SCAN arrows to

The last PTY selected will be used for seek or scan
modes. If a station with the selected PTY is not found,
NONE FOUND will appear on the display. If both
P
-TYPE and TRAF are on, the radio will search
for stations with traffic announcements and the
selected PTY.
To use the P
-TYPE interrupt feature, press and hold
the P
-TYPE button until you hear a beep on the
PTY you want to interrupt on. When you are listening
to a compact disc, the last selected RDS FM station
will interrupt play if that selected program type format
is broadcast.
AM FM: The AM FM button operates the alternate
frequency feature. Alternate frequency allows the radio to
switch to a stronger station with the same program type.Press and hold AM FM for two seconds to turn alternate
frequency on. AF ON will appear on the display. The
radio may switch to stronger stations. Press and hold
AM FM again for two seconds to turn alternate
frequency off. AF OFF will appear on the display.
The radio will not switch to other stations.
Setting PTY Preset Stations
The six numbered pushbuttons let you return to your
favorite Program Types (PTYs). These buttons have
factory PTY presets. You can set up to 12 PTYs
(six FM1 and six FM2) by performing the
following steps:
1. Press AM FM to select FM1 or FM2.
2. Press P-TYPE, if it is not already on.

if the tuned station broadcasts traffic announcements.
If the current tuned station does not broadcast traffic
announcements, the radio will seek to a station that
does. When the radio finds a station that broadcasts
traffic announcements, it will stop. If no station is found,
NONE FOUND will appear on the display.
When a traffic announcement comes on the tuned radio
station or a related network station, you will hear it,
even if the volume is muted or a compact disc is

following conditions:

The road is too rough. The disc should play when
the road is smoother.

The disc is dirty, scratched, wet or upside down.

The air is very humid. If so, wait about an hour
and try again.
If any error occurs repeatedly or if an error can't be
corrected, please contact your dealer. If your radio
displays an error message, write it down and provide it
to your dealer when reporting the problem.Rear Seat Entertainment System
(RSE) (If Equipped)
Your vehicle may have the optional Digital Versatile
Disc (DVD) entertainment system. The entertainment
system includes a DVD player, a video display screen,
two sets of IR wireless headphones, a remote control
and an instructional video disc.
Before You Drive
The video entertainment system is for passengers in
the second and third row seats only. The driver cannot
safely view the video screen while driving and should
not try to do so.
In severe or extreme temperature conditions your
entertainment system should not be operated until the
temperature is within the operating range. This will keep
your video components from being damaged when the
temperature is below
-4F (-20C) or above 140F (60C).
To resume operation, shut off the entertainment system,
pull down the video screen and then heat or cool the vehicle
until the temperature is within the operating range.

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
headphone volume control will only operate when the
DVD player power is turned on and it controls both wired
headphone jacks at the same time. See ªRemote Controlº
later in this section for more information.
Audio Speakers
Audio from the DVD player can only be heard either
through the IR headphones or wired headphones
(not included). The sound will not come through the
vehicle's speakers.
