Rear Seat Audio (RSA)
This feature allows rear seat passengers to listen to any
of the audio sources: radio, cassette tapes, CDs, or
DVDs, depending on your vehicles options. 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 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. The front seat audio controls always
override the RSA controls.
Rear Seat Audio Controls
The following functions are controlled by the RSA
system buttons:
P(Power):Press this button to turn the rear seat
audio system on or off. The rear speakers will be muted
when the power is turned on unless your vehicle is

Radio Reception
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like storms and power lines. Try
reducing the treble to reduce this noise.
FM Stereo
FM stereo will give you the best sound, but FM signals
will reach only about 10 to 40 miles (16 to 65 km).
Tall buildings or hills can interfere with FM signals,
causing the sound to come and go.
XMŸ Satellite Radio Service
(48 Contiguous US States)
XMŸ Satellite Radio gives you digital radio reception
from coast to coast. Just as with FM, tall buildings
or hills can interfere with satellite radio signals, causing
the sound to come and go. Your radio may display
NO SIGNAL to indicate interference.
