Rear Seat Audio (If Equipped)
This feature allows rear seat passengers to listen to any
of the music sources including AM
or 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 override the rear seat
audio controls.
Note that this feature is intended for rear
seat passengers.
