7-44 Infotainment System 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) System For vehicles with Rear Seat Audio (RSA), rear seat passengers can listen to and control any of the music sources: radio, CDs, DVDs, or other auxiliary sources. 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 a CD and listen to it 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 RSA functions operate even when the main radio is off. The front audio system displays X when the RSA is on, and disappears from the display when it is off. Audio can be heard through wired headphones (not included) plugged into the jacks on the RSA. If the vehicle has this feature, audio can also be heard on Channel 2 of the wireless headphones. The audio system mutes the rear speakers when the RSA audio is active through the headphones. To listen to an iPod or portable audio device through the RSA, attach the iPod or portable audio device to the front auxiliary input (if available), located on the front audio system. Turn the iPod on, then choose the front auxiliary input with the RSA SRCE button. 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 Use only a clean cloth dampened with clean water. Use care when directly touching or cleaning the screen, as damage could result.
