Navigation/Radio System
Your vehicle may have a navigation radio system.
The navigation system has built-in features
intended to minimize driver distraction. Technology
alone, no matter how advanced, can never replace
your own judgment. See the Navigation System
manual for some tips to help you reduce
distractions while driving.
Rear Seat Entertainment System
Your vehicle may have the Digital Versatile
Disc (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 displays Parental Control ON and the
power indicator light on the DVD player ashes.It also disables 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 can 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.
Headphones
The RSE system includes two sets of wireless
headphones.
Each set of headphones has an ON/OFF control.
An indicator light illuminates on the headphones
when they are on. If the light does not illuminate,
the batteries may need to be replaced. See “Battery
Replacement” following for more information.
Each set of headphones has a volume knob.
To adjust the volume, adjust this knob.
284

The transmitters are located below the video display
screen. The headphones shut off automatically if
they lose the signal from the system after about
four minutes to save battery power. The signal
can be lost if the system is turned off or if the
headphones are out of range of the transmitters.
When using the wired headphones, if the front
seat passengers play a CD in the Radio with
Six-Disc CD (if equipped) or use XM™ Satellite
Radio Service (if equipped), you will hear the
audio for these sources, instead of the DVD or
CD that is currently playing through the RSE.
Notice:Do not store the headphones in heat
or direct sunlight. This could damage the
headphones and repairs will not be covered
by your warranty. Keep the headphones stored
in a cool, dry place.
Both sets of rear seat headphones may include
foam ear pads that can be replaced.
Foam ear pads on these headphones can become
worn or damaged. The headphone foam ear pads
can become damaged if they are not handled orstored properly. If the foam ear pads do become
damaged or worn out, the pads can be replaced
separately from the headphone set. It is not
necessary to replace the complete headphone set.
The headphone replacement foam ear pads can
be ordered in pairs. See your dealer/retailer
for more information.
Battery Replacement
To change the batteries, do the following:
1. Loosen the screw on the battery compartment
door located on the left side of the headphone
earpiece.
2. Replace the two AAA batteries in the
compartment. Make sure that they are

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

window below the video screen and press the
desired button. Direct sunlight or very bright
light can 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 can also
affect the function of the remote control.
Notice:Storing the remote control in a hot
area or in direct sunlight can damage it,
and the repairs will not be covered by your
warranty. Keep the remote control stored
in a cool, dry place.
To extend the life of the batteries, the remote
control does not have a press and hold feature.
