DVD Distortion Video distortion can occur when operating cellular phones, scanners, CB radios, Global Position Systems (GPS)*, two-way radios, mobile fax, or walkie talkies. It might be necessary to turn off the DVD player when operating one of these devices in or near the vehicle. *Excludes the OnStar® System. Rear Seat Audio (RSA) Vehicles with this feature allow the rear seat passengers to listen to and control any of the music sources: radio, CDs, DVDs, or other auxiliary sources. However, the rear seat passengers can only control the music sources the front seat passengers are not listening to (except on some radios where dual control is allowed). For example, rear seat passengers can control and listen to a CD through the headphones, while the driver listens to the radio through the front speakers. The rear seat passengers have control of the volume for each set of headphones. The radio functionality is controlled by both the RSA and the front radio. Only one band can be tuned to at one time. Changing the band on the RSA or the front radio will change the band on the other system, if they are both sourced to the radio. Cleaning the RSE Overhead Console When cleaning the RSE overhead console surface, use only a clean cloth dampened with clean water. Cleaning the Video Screen When cleaning the video screen, use only a clean cloth dampened with clean water. Use care when directly touching or cleaning the screen, as damage could result. 4-145
