Rear Seat Audio (RSA) (Without Entertainment System) This feature allows rear seat passengers to listen to and control any of the music sources: radio 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 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. The rear speakers will be muted when the RSA power is turned on. You may operate the RSA functions even when the main radio is off. Rear Seat Radio Controls The following functions are controlled by the RSA system buttons: PWR (Power): Press this button to turn RSA on or off. VOL (Volume): Press this knob lightly so it extends. Turn the knob to increase or to decrease volume. Push the knob back into its stored position when you are not using it. The upper VOL knob controls the upper headphone and the lower VOL knob controls the lower headphone. Primary Radio Controls The following function is controlled by the knob on the main radio: PWR (Power): Press this knob twice to turn RSA off. 3-107
