Playing a Cassette Tape
Your tape player is built to work best with tapes that are
up to 30 to 45 minutes long on each side. Tapes longer
than that are so thin they may not work well in this
player. The longer side with the tape visible should face
to the right. If the ignition is on, but the radio is off, the
tape can be inserted and will begin playing. A tape
symbol is shown on the display whenever a tape is
inserted. If you hear nothing but a garbled sound, the
tape may not be in squarely. Press EJT to remove the
tape and start over.
While the tape is playing, use the VOL, FADE, BAL,

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.

3-38 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 or CLEAN
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 dealership
(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 cut tape detection feature
and a cleaning cassette may appear as a broken tape.
To prevent the cleaning cassette from being ejected, use
the following steps.
If your vehicle is equipped with the AM
-FM Stereo with
Cassette Tape Player:
1. Turn the ignition to ON or ACC.
1. Turn the radio off.
2. Press and hold the TAPE button for five
seconds. CAS will flash on the display will flash
for five seconds.
3. Insert the scrubbing action cleaning cassette.
4. Eject the cleaning cassette after the manufacturer's
recommended cleaning time.

3-39
If your vehicle is equipped with the AM-FM Stereo with
Cassette Tape Player with Radio Data System and
Automatic Tone Control or the AM
-FM Stereo with
Cassette Tape and Compact Disc Player with Radio Data
System and Automatic Tone Control:

Turn the ignition to ON or ACC.

Turn the radio off.

Press and hold the TAPE AUX or TAPE CD button
for five seconds. READY will appear on the display
for five seconds.

Insert the scrubbing action cleaning cassette.

Eject the cleaning cassette after the manufacturer's
recommended cleaning time.
When the cleaning cassette has been ejected, the cut tape
detection feature is active again.
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 the eject or
EJT button for five seconds to reset the CLN or CLEAN
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.
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 signal surface 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.

6-17 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
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 changes will vary depending on how you drive your
vehicle
-- usually between 3,000 miles (5 000 km) and
7,500 miles (12 500 km) since your last oil change.
Under severe conditions, the system may come on
before 3,000 miles (5 000 km). Never drive your vehicle
more than 7,500 miles (12 500 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 every
3,000 miles (5 000 km) or sooner. Remember to reset
the CHG OIL SOON light whenever the oil is changed.How to Reset the Change Oil Message
After changing the engine oil, the system must be reset.
To reset the CHG OIL SOON message:
1. Turn the ignition to ACC or ON and the radio off.
2. Press and hold the DISP button on the radio for at
least five seconds until SETTINGS is displayed.
3. Press the SEEK up or down arrow to scroll through
the main menu.
4. Scroll until OIL LIFE appears on the display.
5. Press the PREV or NEXT button to enter the
submenu. RESET will be displayed.
6. Press the DISP button to reset. A chime will be heard
to verify the new setting and DONE will be
displayed for one second.
7. Once the message has been reset, scroll until EXIT
appears on the display.
8. Press the DISP button to exit programming. A chime
will be heard to verify the exit.

6-28 How to Check Power Steering Fluid
When the engine compartment is cool, 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.
When the 3400 V6 engine compartment is hot, the level
should be at the ªHº mark. When it's cold, the level
should be at the ªCº mark. If the fluid is at the
ADD mark, you should add fluid.
For the 3800 V6 engine, the level should be at the
HOT mark when the engine compartment is hot.
If the fluid is at the ADD mark, you should add fluid.
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 this message is
displayed, it means the
vehicle is low on windshield
washer fluid. You should
add more windshield
washer fluid soon.

8. Press the DISP button to exit programming.
A chime will be heard to verify exit.
The system completes the calibration process during driving.The system normally takes 15 to 20 minutes of driving
in each of three speed ranges to ªlearnº tire pressures.
The speed ranges are 15 to 40 mph (25 to 65 km/h),
40 to 65 mph (65 to 105 km/h) and above 65 mph
(105 km/h). When learning is complete, the system will
alert you after 2
-8 minutes if a tire is 12 psi (83 kPa)
different from the other three tires. Detection thresholds
may be higher and detection times may be longer on
rough roads, curves and at high speeds. The system is
not capable of detection at speeds greater than 70 mph
(110 km/h).
Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to 13 000 km). Any time you notice unusual
wear, rotate your tires as soon as possible and check
wheel alignment. Also check for damaged tires or wheels.
See ªWhen It's Time for New Tiresº and ªWheel
Replacementº later in this section for more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation is the most important. See ªScheduled
Maintenance Servicesº in the Index for scheduled
rotation intervals.
