Using RDS
Your audio system is equipped with a Radio Data
System (RDS). RDS features are available for use only
on FM stations that broadcast RDS information.
·Seek to stations broadcasting the selected type of
programming,
·receive announcements concerning local and
national emergencies,
·display messages from radio stations, and
·seek to stations with traffic announcements.
This system relies upon receiving speci®c information
from these stations and will only work when the
information is available. In rare cases, a radio station
may broadcast incorrect information that will cause
the radio features to work improperly. If this happens,
contact the radio station.
While you are tuned to an RDS station, the station
name or the call letters will appear on the display instead
of the frequency. RDS stations may also provide the
time of day, a program type (PTY) for current
programming and the name of the program being
broadcast.

Rear Seat Audio (RSA)
This feature allows rear seat passengers to listen to and
control any of the music sources: radio, cassette
tapes and 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
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.
Primary Radio Controls
The following function is controlled by the knob on the
main radio:
PWR (Power):Push this knob twice to turn RSA off.
Rear Seat Radio Controls
The following functions are controlled by the RSA
system buttons:
PWR (Power):Press this button to turn RSA on or off.
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.
VOL (Volume):Press this knob lightly so it extends.
Turn the knob to increase or to decrease volume. Push
the knob back into its stored position when you're
not using it. The upper VOL knob controls the upper
headphone and the lower VOL knob controls the lower
headphone.

Cassette Tape Player Service
Clean cassette tape player. Cleaning should be done
every 50 hours of tape play. SeeAudio System(s)
on page 3-40for further details.
At Least Twice a Year
Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages
are working properly. Look for any other loose or
damaged safety belt system parts. If you see anything
that might keep a safety belt system from doing its
job, have it repaired. Have any torn or frayed safety belts
replaced.
Also look for any opened or broken air bag coverings,
and have them repaired or replaced. (The air bag
system does not need regular maintenance.)
Wiper Blade Check
Inspect wiper blades for wear or cracking. Replace
blade inserts that appear worn or damaged or that
streak or miss areas of the windshield. Also see
Cleaning the Outside of Your Vehicle on page 5-84.
Spare Tire Check
At least twice a year, after the monthly in¯ation check of
the spare tire determines that the spare is in¯ated to
the correct tire in¯ation pressure, make sure that
the spare tire is stored securely. Push, pull, and then try
to rotate or turn the tire. If it moves, use the
ratchet/wheel wrench to tighten the cable. See
Changing
a Flat Tire on page 5-65.
Weatherstrip Lubrication
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth. During very cold,
damp weather more frequent application may be
required. See
Part D: Recommended Fluids and
Lubricants on page 6-18.
Automatic Transmission Check
Check the transmission ¯uid level; add if needed. SeeAutomatic Transmission Fluid on page 5-19. A ¯uid loss
may indicate a problem. Check the system and repair
if needed.

Replacing Brake System Parts
The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together if
the vehicle is to have really good braking. Your
vehicle was designed and tested with top-quality GM
brake parts. When you replace parts of your braking
system Ð for example, when your brake linings
wear down and you need new ones put in Ð be sure
you get new approved GM replacement parts. If
you don't, your brakes may no longer work properly. For
example, if someone puts in brake linings that are
wrong for your vehicle, the balance between your front
and rear brakes can change Ð for the worse. The
braking performance you've come to expect can change
in many other ways if someone puts in the wrong
replacement brake parts.
Battery
Your new vehicle comes with a maintenance free
ACDelcožbattery. 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
ž
battery. SeeEngine Compartment Overview on
page 5-12for 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 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.

Feature (Non-RDS Radios) on page 3-73orTheft-Deterrent Feature (RDS Radios) on page 3-73.
