3-31 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 will display CLEAN TAPE
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 the tape or the tape player is at fault. If this other
cassette has no improvement in sound quality, clean the
tape player.
For best results, use 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).For vehicles with the single compact disc player, use the
following steps:
1. Turn the ignition to ON or ACCESSORY.
2. Turn the radio on.
3. Insert the scrubbing action cleaning cassette.
4. Eject the cleaning cassette after the manufacturer's
recommended cleaning time.
For vehicles with the six
-disc compact disc player, when
cleaning the cassette tape player with the recommended
non
-abrasive cleaning cassette, it is possible that the
cassette may eject, because the cut tape detection feature
on your radio may recognize it as a broken tape, in error.
To prevent the cleaning cassette from being ejected, use
the following steps:
1. Turn the ignition to ON or ACCESSORY.
2. Turn the radio on.
3. Insert the scrubbing action cleaning cassette.
4. Eject the cleaning cassette after the manufacturer's
recommended cleaning time.

3-32
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, perform the following steps:
1. Press the TUNE/SEL knob.
2. Turn the TUNE/SEL knob until SETUP is displayed.
3. Press the TUNE/SEL knob to enter SETUP.
4. Turn the TUNE/SEL knob until CLEAR TAPE
HOURS is displayed.
5. Press the TUNE/SEL knob to select. The radio
will display CLEARED to show that 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.
Care of Your Compact Discs
Handle discs carefully. Store them in their original cases
or other protective cases and away from direct sunlight
and dust. If the surface of a disc is soiled, dampen a
clean, soft cloth in a mild, neutral detergent solution and
clean it, wiping from the center to the edge.
Be sure never to touch the side without writing when
handling discs. Pick up discs by grasping the outer edges
or the edge of the hole and the outer edge.
Care of Your Compact Disc Player
The use of CD lens cleaner discs is not advised, due to
the risk of contaminating the lens of the CD optics with
lubricants internal to the CD mechanism.

NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
starburst symbol. Failure to use the
recommended oil can result in engine damage not
covered by your warranty.
GM Goodwrench
oil meets all the requirements for
your vehicle.
If you are in an area where the temperature falls below
-20F (-29C), consider using either an SAE 5W-30
synthetic oil or an SAE 0W
-30 oil. Both will provide
easier cold starting and better protection for your engine
at extremely low temperatures.
Engine Oil Additives
Don't add anything to your oil. The recommended oils
with the starburst symbol are all you will need for good
performance and engine protection.
When to Change Engine Oil
(GM Oil Life System)
Your vehicle has a computer system that lets you know
when to change the engine oil and filter. This is based
on engine revolutions and engine temperature, and not
on mileage. Based on driving conditions, the mileage
at which an oil change will be indicated can vary
considerably. For the oil life system to work properly,
you must reset the system every time the oil is changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is
necessary. A Change Engine Oil message in the DIC
will come on. Change your oil as soon as possible
within the next two times you stop for fuel. It is possible
that, if you are driving under the best conditions, the oil
life system may not indicate that an oil change is
necessary for over a year. However, your engine oil and
filter must be changed at least once a year and at this
time the system must be reset. It is also important to
check your oil regularly and keep it at the proper level.
If the system is ever reset accidentally, you must change
your oil at 3,000 miles (5 000 km) since your last oil
change. Remember to reset the oil life system whenever
the oil is changed.

6-15
How to Reset the Change Engine Oil Message and
the Oil Life Indicator
The GM Oil Life System
calculates when to change
your engine oil and filter based on vehicle use. Anytime
your oil is changed, reset the system so it can calculate
when the next oil change is required. If a situation
occurs where you change your oil prior to a Change
Engine Oil message in the DIC being turned on, reset
the system.
After the oil has been changed, the Change Engine
Oil message and the oil life indicator must be reset.
To reset the message and indicator, use one of the
following procedures:Base Audio System
Press the CLR button located to the right of the DIC
display to acknowledge the CHANGE ENGINE OIL
message. This will clear the message from the display
and reset it.
To reset the oil life indicator, use the following steps:
1. Press the up or down arrow on the INFO button
located to the right of the DIC display to access the
DIC menu.
2. Once XXX% ENGINE OIL LIFE menu item is
highlighted, press and hold the CLR button.
The percentage will return to 100, and the oil life
indicator will be reset.
3. Repeat the steps if the percentage does not
return to 100.
