Rear Seat Audio (RSA) This feature allows rear seat passengers to listen to and control any of the music sources: radio, cassette tapes and CDs. However, the rear seat passengers can only control the music sources that the front seat passengers are not listening to. For example, rear seat passengers may listen to a cassette tape or CD through 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. Be aware that the front seat audio controls always have priority over the RSA controls. If the front seat passengers switch the source for the main radio to a remote source, the RSA will play the same remote source. Primary Radio Controls The following function is controlled by the knob on the main radio: PWR (Power): Push this knob twice to turn RSA off. 3-71
