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.

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.

6-45 Tire Inflation Monitor System
(If Equipped)
The tire inflation monitor system can alert you to a large
change in the pressure of one tire. The system ªlearnsº
the pressure at each tire throughout the operating speed
range of your vehicle. The system normally takes
between 45 and 90 minutes of driving to learn the tire
pressures. This time may be longer depending on your
individual driving habits. Learning need not be
accumulated during a single trip. Once learned, the
system will remember the tire pressures until the system
is recalibrated.
After the system has learned tire pressures with properly
inflated tires, the LOW TIRE PRESSURE light will come
on if the pressure in one tire becomes 12 psi (83 kPa)
lower than the other three tires. The tire inflation monitor
system won't alert you if the pressure in more than one
tire is low, if the system is not properly calibrated, or if the
vehicle is moving faster than 70 mph (110 km/h).
The tire inflation monitor system detects differences in
tire rotation speeds that are caused by changes in tire
pressure. The system can alert you about a low
tire
-- but it doesn't replace normal tire maintenance.
See ªTiresº in the Index.When the LOW TIRE PRESSURE light comes on, 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.
The light will come on and stay on until you turn off the
ignition or reset (calibrate) the system.
Don't reset the tire inflation monitor 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 system
will not work properly and may not alert you when a
tire is low.
Any time you adjust a tire's pressure, rotate your tires,
or have one or more tires repaired or replaced, you'll
need to reset (calibrate) the tire inflation monitor
system. You'll also need to reset the system whenever
you buy new tires and whenever the vehicle's battery
has been disconnected.

yellowblue
6-46
To reset (calibrate) the system: The tire inflation
monitor system can be reset by turning the exterior lamp
control from OFF to parking lamps three times while the
ignition is in ON. It can also be reset through ªVehicle
Customization Settings.º To reset the monitor using the
vehicle customization settings:
1. Turn the ignition to ACC or ON and turn 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 TIRE MON 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 monitor 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 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.

Traction -- AA, A, B, C
The traction grades, from highest to lowest, are AA, A,
B, and C. Those grades represent the tire's ability to stop
on wet pavement as measured under controlled
conditions on specified government test surfaces of
asphalt and concrete. A tire marked C may have poor
traction performance. Warning: The traction grade
assigned to this tire is based on straight
-ahead braking
traction tests, and does not include acceleration,
cornering, hydroplaning, or peak traction characteristics.
Temperature
-- A, B, C
The temperature grades are A (the highest), B, and C,
representing the tire's resistance to the generation of
heat and its ability to dissipate heat when tested under
controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the
material of the tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire failure.
The grade C corresponds to a level of performance
which all passenger car tires must meet under the
Federal Motor Vehicle Safety Standard No. 109. Grades
B and A represent higher levels of performance on the
laboratory test wheel than the minimum required by law.Warning: The temperature grade for this tire is
established for a tire that is properly inflated and not
overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in combination,
can cause heat buildup and possible tire failure.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
carefully at the factory to give you the longest tire life
and best overall performance.
Scheduled wheel alignment and wheel balancing are not
needed. However, if you notice unusual tire wear or your
vehicle pulling one way or the other, the alignment may need
to be reset. If you notice your vehicle vibrating when driving
on a smooth road, your wheels may need to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted
or corroded. If wheel nuts keep coming loose, the wheel,
wheel bolts and wheel nuts should be replaced. If the
wheel leaks air, replace it (except some aluminum
wheels, which can sometimes be repaired). See your
dealer if any of these conditions exist.
Your dealer will know the kind of wheel you need.

Scheduled Maintenance
yellowblue
7-6Engine Oil Scheduled Maintenance
Change engine oil and filter as indicated by the
GM Oil Life System
(or every 12 months, whichever
occurs first). Reset the system. The system will show
you when to change the oil
-- usually between
3,000 miles (5 000 km) and 7,500 miles (12 500 km)
since your last oil change. Under severe conditions, the
indicator 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 without an oil and
filter 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 if the CHANGE
OIL SOON light appears. Remember to reset the Oil
Life System when the oil and filter have been changed.
See ªOil Life Systemº in the Index for information
on resetting.
