Rear Seat Audio (RSA)
This feature allows rear seat passengers to listen to any
of the music sources: radio, cassette tapes or CDs.
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. The front seat audio
controls always override the rear seat audio controls.

CD) using the remote keyless entry transmitter. This
feature can also store and recall AM and FM presets,
volume, tone and the last selected radio station.The number on the back of each transmitter (1 or 2)
corresponds to driver 1 or 2. If transmitter 1 is used to
enter the vehicle, the last used audio source and/or
settings set by driver 1 will be recalled. If transmitter 2 is
used to enter the vehicle, the last used audio source
and/or settings set by driver 2 will be recalled.
Theft-Deterrent Feature

radio. The feature works automatically by learning
a portion of the Vehicle Identi®cation Number (VIN). If
the radio is moved to a different vehicle, it will not
operate and LOCKED will be displayed.
When the radio and vehicle are turned off, the blinking
red light indicates that THEFTLOCK
žis armed.

DVD Distortion

It may be necessary to turn off the DVD player
when operating one of these devices in or near the
vehicle.
* Excludes the OnStar
žSystem.
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
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.

Vehicle Storage
If you're not going to drive your vehicle for 25 days or
more, remove the black, negative (-) cable from
the battery. This will help keep your battery from
running down.
{CAUTION:
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
aren't careful. See ªJump Startingº next for
tips on working around a battery without
getting hurt.
Contact your dealer to learn how to prepare your
vehicle for longer storage periods.
Also, for your audio system, see
Theft-Deterrent
Feature (RDS Radios) on page 3-104.
Jump Starting
If your battery has run down, you may want to use
another vehicle and some jumper cables to start your
vehicle. But please use the following steps to do it
safely.
{CAUTION:
Batteries can hurt you. They can be dangerous
because:
·They contain acid that can burn you.
·They contain gas that can explode or
ignite.
·They contain enough electricity to
burn you.
If you don't follow these steps exactly, some
or all of these things can hurt you.
