Rear Seat Entertainment System
Your vehicle may have a DVD Rear Seat
Entertainment (RSE) system. While playing a DVD or
audio CD in the RSE, press the CD key to view the RSE
screen and to switch to DVD as your main audio
source. At this point, you will hear what is being played
in the RSE system through all of the vehicle's
speakers. From the RSE screen you can mute the Front
or Rear speakers, mute RSE entirely, or turn off RSE.
When the RSE system is turned off, you must turn
it back on from the RSE system. It cannot be turned
back on through the navigation system radio.
