seat video system is an available option. Several com-
binations of radio receivers are offered on this model.
The audio/video system uses an ignition switched
source of battery current so that the system will only
operate when the ignition switch is in the RUN or
ACCESSORY/ACCESSORY DELAY positions.

The audio system includes the following compo-

nents:

• Amplifier

• Antenna

• CD changer (if equipped)

• DVD player (if equipped)

• Radio noise suppression components

• Radio receiver

• Speakers

• Video screen (if equipped)
Certain functions and features of the audio/video

system rely upon resources shared with other elec-
tronic modules in the vehicle over the Programmable
Communication Interface (PCI) bus network. The
data bus network allows the sharing of sensor infor-
