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 to Rear Seat Audio (RSA) on page 347
for 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.
