Rear Entertainment System Pressing the REAR CTRL OFF button disables rear control. The indicator in the button comes on and your passengers can no longer operate the system with the rear control panel. When the button is pressed, the ''CTRL OFF'' message appears in the overhead screen to let your passengers know that the control panel is disabled. The rear system selects the source it was last set to. If that source has been removed (the DVD has been ejected from the player, for example), you will see ''No Disc'' in the display. You should select another source or insert a DVD. Rear Speakers When you turn on the system, the rear speakers are automatically turned off if the rear system selects a different entertainment source than the front system. You will see the Rear Speakers Off icon both in the audio display and the overhead screen. The sound for the rear system is sent to the wireless headphones. If you want to turn the rear speakers on again, press and hold the REAR PWR button until the Rear Speakers Off icon goes off. NOTE: The rear speakers are connected to the front system, so they will always play the source that the front system is set to. Features CONTINUED 311
