All of the CD functions are controlled by the radio
buttons except for ejecting the magazine. Whenever a
CD magazine with discs is loaded in the changer,
CHNGR will appear on the radio display. If the CD
changer is checking the magazine for CDs, CHNGR will
flash on the display until the changer is ready to play.
When a CD begins playing, the disc and track number
will be displayed. The disc numbers are listed on the
front of the magazine.
Compact Disc Changer Errors
If E and a number appear on the display, an error has
occurred and the compact disc temporarily cannot play.
The CD changer will send an error message to the
receiver to indicate:

E30: Disc Loaded Incorrectly (Label Side Up)

road is smoother.

The disc is dirty, scratched, wet or upside down.
The air is very humid. If so, wait about an hour and
try again.

The CD changer door is open. Completely close the
door to restore normal operation.

An empty magazine is inserted in the CD changer.
Try the magazine again with a disc loaded on one of
the trays.
If any error occurs repeatedly or if an error cannot be

settings as adjusted the last time your vehicle was
operated. This feature allows two different drivers to
store and recall their own radio settings for AM and
FM presets, last tuned station, volume, tone and audio
source (radio, cassette or CD). The settings recalled
by the radio are determined by which transmitter
(ª1º or ª2º) was used to enter the vehicle. The number
on the back of the transmitter corresponds to driver 1 or
to driver 2. After the unlock button is pressed on the
transmitter and the ignition is in RUN, the radio settings
will automatically adjust to where they were last set by
the identified driver. The settings can also be changed by
pressing one of the MEMORY buttons (1 or 2) located
on the driver's door until you hear two beeps. When
changes are made, the new settings will be saved for
the driver.

3-27 Care of Your Cassette Tape Player
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes or a damaged
mechanism. Cassette tapes should be stored in their
cases away from contaminants, direct sunlight and
extreme heat. If they aren't, they may not operate
properly or may cause failure of the tape player.
Your tape player should be cleaned regularly after every
50 hours of use. Your radio may display CLN to indicate
that you have used your tape player for 50 hours without
resetting the tape clean timer. If this message appears on
the display, your cassette tape player needs to be
cleaned. It will still play tapes, but you should clean it as
soon as possible to prevent damage to your tapes and
player. If you notice a reduction in sound quality, try a
known good cassette to see if it is the tape or the tape
player at fault. If this other cassette has no improvement
in sound quality, clean the tape player.
The recommended cleaning method for your cassette
tape player is the use of a scrubbing action,
non
-abrasive cleaning cassette with pads which scrub
the tape head as the hubs of the cleaner cassette turn.
The recommended cleaning cassette is available through
your dealer (GM Part No. 12344789).When using a scrubbing action, non
-abrasive cleaning
cassette, it is normal for the cassette to eject because
your unit is equipped with a broken tape detection
feature and a cleaning cassette may appear as a broken
tape. If the cleaning cassette ejects, insert the cassette
at least three times to ensure thorough cleaning.
You may also choose a non
-scrubbing action, wet-type
cleaner which uses a cassette with a fabric belt to clean
the tape head. This type of cleaning cassette will not
eject on its own. A non
-scrubbing action cleaner may
not clean as thoroughly as the scrubbing type cleaner.
The use of a non
-scrubbing action, dry-type cleaning
cassette is not recommended.
After you clean the player, press and hold EJECT for
five seconds to reset the CLN indicator. The radio will
display
--- to show the indicator was reset.
Cassettes are subject to wear and the sound quality
may degrade over time. Always make sure the cassette
tape is in good condition before you have your tape
player serviced.

6-16 When to Change Engine Oil (Vehicles With
the GM Oil Life System
Option)
If so equipped, your vehicle has a computer that lets you
know when to change your engine oil. This is not based
on mileage, but on engine revolutions and engine
operating temperature. When the computer has
calculated that the oil needs changing, the GM Oil Life
System
will indicate that a change is necessary.
The mileage between oil and filter changes will vary
depending on how you drive your vehicle
-- usually
between 3,000 miles (5 000 km) and 10,000 miles
(16 000 km) since your last oil and filter change. Under
severe conditions, the system may come on before
3,000 miles (5 000 km). Never drive your vehicle more
than 10,000 miles (16 000 km) or 12 months
(whichever occurs first) without an oil change.
The system won't detect dust in the oil. So, if you drive
in a dusty area, be sure to change your oil and filter
every 3,000 miles (5 000 km) or sooner. Remember to
reset the Oil Life System whenever the oil is changed.How to Reset the Oil Life System (If Equipped)
Always reset the engine oil life to 100% after every oil
change. It will not reset itself. To reset the Oil Life
System, press and hold the DIC RESET button for more
than five seconds while the OIL LIFE INDEX is being
displayed on the DIC. The oil life will change to 100%.
What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don't let used oil stay on your skin
for very long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly throw
away clothing or rags containing used engine oil.
See the manufacturer's warnings about the use and
disposal of oil products.
Used oil can be a real threat to the environment. If you
change your own oil, be sure to drain all free
-flowing oil
from the filter before disposal. Don't ever dispose of oil
by putting it in the trash, pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle it by taking it to a place that collects used oil.
If you have a problem properly disposing of your used
oil, ask your dealer, a service station or a local recycling
center for help.

6-28 How to Check Power Steering Fluid
Turn the key off, let the engine compartment cool down,
wipe the cap and the top of the reservoir clean, then
unscrew the cap and wipe the dipstick with a clean rag.
Replace the cap and completely tighten it. Then remove
the cap again and look at the fluid level on the dipstick.
The level should be at the FULL COLD mark.
If necessary, add only enough fluid to bring the level up
to the mark.
What to Use
To determine what kind of fluid to use, see
ªRecommended Fluids and Lubricantsº in the Index.
Always use the proper fluid. Failure to use the proper
fluid can cause leaks and damage hoses and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer's instructions before use. If you will be
operating your vehicle in an area where the temperature
may fall below freezing, use a fluid that has sufficient
protection against freezing.
Adding Washer Fluid
When the windshield washer fluid reservoir is low,
WINDSHIELD WASHER FLUID LOW will be
displayed on the DIC (if equipped).

6-49
When the TIRE PRESSURE LOW message appears on
the Driver Information Center, you should stop as soon
as you can and check all your tires for damage. If a tire
is flat, see ªIf a Tire Goes Flatº in the Index. Also check
the tire pressure in all four tires as soon as you can.
See ªInflation
-Tire Pressureº in the Index.
Any time you adjust a tire's pressure or have one or
more tires repaired or replaced, you'll need to reset
(calibrate) the check tire pressure system. You'll also
need to reset the system whenever you rotate the tires,
buy new tires, install or remove the compact spare, and
whenever the vehicle's battery has been disconnected.
Don't reset the check tire pressure system without first
correcting the cause of the problem and checking and
adjusting the pressure in all four tires. If you reset the
system when the tire pressures are incorrect, the check
tire pressure system will not work properly and may not
alert you when a tire is low or high.To reset (calibrate) the system:
1. Turn the ignition switch to RUN.
2. Press the GAGE INFO button on the DIC until
TIRE PRESSURE appears on the display.
3. Press and hold the DIC RESET button for about
five seconds. After five seconds, the display will
show TIRE PRESSURE RESET. If TIRE
PRESSURE RESET does not appear on the display
after about five seconds, see your dealer for service.
After you release the DIC RESET button, TIRE
PRESSURE NORMAL will appear on the display.
The system completes the calibration process during
driving. Calibration time can take 45 to 90 minutes,
depending on your driving habits. After the system has
been calibrated, the system will alert the driver that a tire
is low, up to a maximum speed of 65 mph (105 km/h).
