Parental Control Button: This button is located on the
front of the DVD console, behind the video screen,
near the driver of the vehicle. 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). The driver will then
be able to gain the attention of the rear seat passengers.
Press this button again to restore normal operation of
the DVD player.
This button may also be used to turn the DVD player
power on and automatically resume play if the vehicle is
in an enabled power mode.
Video Screen
The video screen is located in the overhead console. To
use the video screen, push forward on the release
latch and the screen will fold down. Adjust the screen's
position as desired. When the video screen is not in
use, push it up into its latched position.
The DVD player and display will continue to operate
when the screen is in either the up or the down position.
The video screen contains the infrared transmitters for
the wireless headphones and the infrared receiver
for the remote control. If the screen is in the closed
position, the infrared signals will not be available for the
operation of the headphones and the remote control.
Notice: Avoid directly touching the video screen, as
damage may occur. Do not touch the video screen.
See "Cleaning the Video Screen" in the Index
for more information.
Remote Control
To use the remote control, aim it at the infrared window
below the video screen and press the desired button.
Direct sunlight or very bright light may affect the ability of
the entertainment system to receive signals from the
remote control. If the remote control does not seem to
be working, the batteries may need to be replaced.
See "Battery Replacement" later in this section.
Objects blocking the line of sight may also affect the
function of the remote control.
