Parental Control
The RSE system may have a Parental Control feature, depending on which radio the vehicle has. To start Parental Control, press and hold the radio power button for more than two seconds to stop all system features such as: radio, video screen, Rear Seat Audio (RSA), DVD, and/or CD. While Parental Control is on, a padlock icon displays.
The radio can be turned back on with a single press of the power button, but the RSE system will remain under Parental Control.
To turn Parental Control off, press and hold the radio power button for more than two seconds. The RSE returns from where it was previously left and the padlock icon disappears from the radio display.
Parental Control can also be turned off by inserting or ejecting any disc, pressing the play icon on the radio DVD display menu, or changing an ignition position.
