Rear Seat Audio (RSA) (If Equipped) 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. This feature is intended for rear seat passengers. The following function is controlled by the knob on the main radio: PWR-VOL: Push this knob twice to turn RSA off. The following functions are controlled by the RSA system buttons: PWR: Press this button to turn RSA on or off. This feature allows rear seat passengers to listen to and control any of the music sources, including AM-FM, cassette tapes and CDs, through the Rear Seat Audio (RSA) controller. 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 the two sets of headphones, (provided in the glove box), while the driver listens to the radio through the front speakers. The rear seat passengers have built-in volume control 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 VOL: Press this knob lightly so it extends. Turn the knob clockwise to increase volume and counterclockwise to decrease volume. Push the knob back into its stored position when you're not using it. The top VOL knob controls the top headphone and the bottom VOL knob controls the bottom headphone. The headphones also have integrated volume control on them. Turn the control up to increase volume and down to decrease volume. AM-FM: Press this button to switch between AM, FM1 and FM2. If the front passengers are already listening to AM-FM, the RSA controller will not switch between the bands and cannot change the frequency. 3-44
