Parental Control
WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
Parental control will pause DVD playback, mute the audio, and display "Parental Control On" with an otherwise blank display screen when turned on. The driver may press the RSE button on the radio/DVD player to initiate or cancel parental control.
