3-16 Rear Seat Audio (RSA)
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 through
headphones and have control over the cassette tape
playing while the driver listens to the radio through the
front speakers. If rear seat passengers choose to listen
to the radio while the driver is listening to the radio they
will not be able to control the radio.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.

3-24 Understanding 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 if you ever get it.
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.
Tips About Your Audio System
Hearing damage from loud noise is almost undetectable
until it is too late. Your hearing can adapt to higher
volumes of sound. Sound that seems normal can be
loud and harmful to your hearing. Take precautions by
adjusting the volume control on your radio to a safe
sound level before your hearing adapts to it.To help avoid hearing loss or damage:

Adjust the volume control to the lowest setting.

Increase volume slowly until you hear comfortably
and clearly.
NOTICE:
Before you add any sound equipment to your
vehicle
-- like a tape player, CB radio, mobile
telephone or two
-way radio -- be sure you
can add what you want. If you can, it's very
important to do it properly. Added sound
equipment may interfere with the operation of
your vehicle's engine, radio or other systems,
and even damage them. Your vehicle's systems
may interfere with the operation of sound
equipment that has been added improperly.
So, before adding sound equipment, check with
your dealer and be sure to check Federal rules
covering mobile radio and telephone units.
