3-57 Rear Seat Audio (If Equipped)
This feature allows rear seat passengers to listen to any
of the music sources including AM
-FM, cassette tapes
or CDs and to use automatic tone control. 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.
This feature is intended for rear seat passengers.
The following functions are controlled by the rear seat
audio system buttons:
VOL: Turn the knob clockwise to increase volume
and counterclockwise to decrease volume. The left VOL
knob controls the left headphone and the right VOL
knob controls the right headphone.
PROG: With a cassette tape in the player and the
radio playing, press this button to play a cassette tape.
Press PROG to switch between the tape and compact
disc if both are loaded. Press PROG again to return
to the radio when a cassette tape or compact disc is
playing. The inactive tape or CD will remain safely
inside the radio for future listening.
PWR: 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 you have a Bose


equipped vehicle. You may operate the rear seat audio
functions even when the primary radio power is off.

If your vehicle has this
feature, certain radio

station. When playing a cassette tape or compact disc,
press AM/FM to switch to the radio.

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.
Understanding DVD Distortion
You may experience audio distortion in the IR
headphones when operating cellular phones, scanners,
CB radios, Global Position Systems (GPS)*, two
-way
radios, mobile fax, or walkie talkies.
It may be necessary to turn off the DVD player when
operating one of these devices in or near the vehicle.
* Excludes the OnStar

System.

3-60 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 do the following:
1. Adjust the volume control to the lowest setting.
2. 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, Delphi Electronics
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.

Battery
Your new vehicle comes with a maintenance free
ACDelco
battery. When it's time for a new battery, get
one that has the replacement number shown on the
original battery's label. We recommend an ACDelco
battery. See ªEngine Compartment Overviewº in the
Index for battery location.
WARNING: Battery posts, terminals and related
accessories contain lead and lead compounds, chemicals
known to the State of California to cause cancer and
reproductive harm. Wash hands after handling.
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 in the Index
for tips on working around a battery without
getting hurt.
Contact your dealer to learn how to prepare your vehicle
for longer storage periods.
