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 flash. 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. Headphones The RSE system includes two sets of wireless headphones. Each set of headphones has an ON/OFF control. An indicator light will illuminate 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. The transmitters are located below the video display screen. The headphones will shut off automatically if they lose the signal from the system after about four minutes to save battery power. The signal may 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. 3-125 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.
