Listening to a DVD
If your vehicle has the Rear Seat Entertainment (RSE)
system and a DVD is playing, the DVD symbol will
appear on the radio display indicating that the DVD is
available and can be listened to through your vehicle’s
speakers.
To listen to the DVD, press the CD AUX button until RSE
appears on the radio display. The current radio source
will stop and the DVD sound will come through the
speakers.
To stop listening to the DVD, press the CD AUX button,
if a CD is loaded, or press the BAND button to select
a different source.
When the RSE system is turned off, the DVD symbol will
go off of the radio display and RSE OFF will appear on
the radio display. The radio will return to the last radio
source that you were listening to.
SeeRear Seat Entertainment System on page 3-115for
more information.
Rear Seat Entertainment System
Your vehicle may have a DVD Rear Seat
Entertainment (RSE) system. The RSE system
includes a DVD player, a video display screen,
two sets of wireless headphones, and a remote
control.
Parental Control
This button is located behind the video screen. Press
this button while a DVD or CD is playing to freeze the
video and mute the audio. The video screen will display
Parental Control ON and the power indicator light on the
DVD player will ash. It will also disable all other button
operations from the remote control and the DVD player,
with the exception of the eject button. Press this button
again to restore operation of the DVD player.
This button may also be used to turn the DVD player
power on and automatically resume play if the ignition
is in RUN, ACCESSORY, or if RAP is active.
Before You Drive
The RSE system is for rear seat passengers only. The
driver cannot safely view the video screen while driving
and should not try to do so.
3-115
Stereo RCA Jacks
The RCA jacks are located behind the video screen. The
RCA jacks allow audio and video signals to be connected
from an auxiliary device such as a camcorder or a video
game unit to the RSE system. Standard RCA cables, not
included, are needed to connect the auxiliary device to
the RCA jacks. The yellow connector inputs video and the
red and white connectors input right and left audio. Refer
to the manufacturer’s instructions for proper connection
of the auxiliary device.
To use the auxiliary inputs on the RSE system, connect
an external auxiliary device to the color-coded RCA jacks
and turn both the auxiliary device and the RSE system
power on. If the RSE system had been previously in the
DVD player mode, pressing the SRCE button on the
faceplate or the remote control will switch the RSE
system between the auxiliary device and the DVD player.
How to Change the Video Format when in
the Auxiliary Mode
The auxiliary input video format is preset to NTSC. In
some countries, the video format may be in the PAL
system. To change the video format, perform the
following:
1. Press the display menu button.
2. Press the down arrow button to highlight the Video
Format option.
3. Press the enter button to select Video Format.
4. Press the right or left arrow button to select
the desired video format.
5. Press the enter button to accept the change.
3-117
Audio Output
Audio from the DVD player or auxiliary inputs may be
heard through the following possible sources:
Wireless Headphones
Vehicle Speakers
Vehicle wired headphone jacks on the Rear Seat
Audio system (if equipped)
The RSE system will always transmit the audio signal
by infrared to the wireless headphones, if there is audio
available. See “Headphones” previously for more
information.
The RSE system is capable of outputting audio to the
vehicle speakers by using the radio. The RSE system
may be selected as an audio source on the radio if the
RSE system power is on. Once the RSE system is
selected as an audio source on the radio, adjust the
speaker volume on the radio, if necessary. If the RSE
system power is not on, the RSE system will not be
an available source on the radio. Refer to the radio
information for the radio that your vehicle has for more
information.
The RSE system is capable of outputting audio to the
wired headphone jacks on the rear seat audio system
(if equipped). The RSE system may be selected as an
audio source on the rear seat audio system if the RSE
system power is on. Refer toRear Seat Audio (RSA)
on page 3-127for more information.
Video Screen
The video screen is located in the overhead console. To
use the video screen, push forward on the release latch
and the screen will fold down. Adjust the screen’s position
as desired. When the video screen is not in use, push it
up into its latched position.
The DVD player and display will continue to operate
when the screen is in the up or the down position. The
video screen contains the transmitters for the wireless
headphones and the remote control. If the screen is in
the closed position, the signals will not be available for
the operation of the headphones or the remote control.
Notice:Avoid directly touching the video screen,
as damage may occur. See “Cleaning the Video
Screen” later in this section for more information.

The DVD player is located in the overhead console. The
DVD player can be controlled by the buttons on the DVD
player and/or by the buttons on the remote control.
See “Remote Control” later in this section for more
information.

window below the video screen and press the desired
button. Direct sunlight or very bright light may affect the
ability of the RSE system to receive signals from the
remote control. If the remote control does not seem to
be working, the batteries may need to be replaced. See
“Battery Replacement” later in this section.
Objects blocking the line of sight may also affect the
function of the remote control.
Notice:Storing the remote control in a hot area or
in direct sunlight may damage it, and the repairs will
