Video Screen
The video screen is located in the overhead console. When the video screen is not in use, push it up into its locked position.
To use the video screen:
1. Push the release button located on the overhead console.
2. Move the screen to the desired position.
If a DVD is playing and the screen is raised to its locked position, the screen remains on; this is normal, and the DVD continues to play through the previous audio source.
Press 
on the remote control or eject the disc to turn off the screen.
The infrared receivers for the wireless headphones and the remote control are located at the rear of the overhead console.
Notice: Avoid directly touching the video screen, as damage may occur. See “Cleaning the Video Screens” later in this section for more information.
