3-29 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 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.
1. Turn the ignition to ON or ACC.
2. Turn the radio off.
3. Press and hold the TAPE AUX button for five
seconds. The tape symbol on the display will flash
for two seconds.
4. Insert the scrubbing action cleaning cassette.
5. 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.

3-30
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.
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.
Fixed Mast Antenna
The fixed mast antenna can withstand most car washes
without being damaged. If the mast should ever become
slightly bent, you can straighten it out by hand. If the
mast is badly bent, as it might be by vandals, you should
replace it.
Check every once in a while to be sure the mast is still
tightened to the rear quarter panel.
Power Antenna Mast Care (If Equipped)
Your power antenna will look its best and work well
if it's cleaned from time to time. To clean the
antenna mast:
1. Turn on the ignition and radio to raise the antenna.
2. Dampen a clean cloth with mineral spirits or
equivalent solvent.
3. Wipe the cloth over the mast sections, removing
any dirt.
4. Wipe dry with a clean cloth.
5. Make the antenna go up and down by turning the
radio or ignition off and on.
6. Repeat if necessary.

4-11
Active Handling System (Option)
The optional Active Handling System is a computer
controlled system that helps the driver maintain
directional control of the vehicle in difficult driving
conditions. This is accomplished by selectively
applying any one of the vehicle's brakes.
When you first start your vehicle and begin to drive
away (6 mph (10 km/h)), the message ACT HNDLG
WARMING UP may be displayed in the DIC, the
instrument cluster light will be on, and a chime will
sound. This is normal. You can acknowledge this
message by pressing the RESET button. The Active
Handling System performance is affected until the
message, WARM UP COMPLETE, is displayed
in the DIC.
In cold weather, the ACT HNDLG WARMING UP
message may continue up to 12 mph (20 km/h).
The Active Handling System is off until the WARM
UP COMPLETE message is displayed.
The ACTIVE HANDLING message will come on when
the system is operating. See ªDriver Information Center
Messagesº in the Index for more information. You may
also feel or hear the system working. This is normal.
The SERVICE ACTIVE
HNDLG message will be
displayed, the instrument
cluster light will come on,
and a chime will sound to
let you know if there is a
problem with the system.
See ªDriver Information
Center Messagesº in the
Index for more information.
When this light and the SERVICE ACTIVE HNDLG
message are on, the system is not operational. Adjust
your driving accordingly.
The Active Handling System comes on automatically
whenever you start your vehicle. To help maintain
directional control of the vehicle, you should always
leave the system on. You can turn the system off if you
ever need to. If you turn the Active Handling System
off, the Traction Control System will also be turned off.
Adjust your driving accordingly.
To turn the system off, press the ACTIVE HANDLING
button on the console. You can turn the system on and off
at any time by pressing the button. The DIC will display
the appropriate message when you push the button.

NOTICE:
After driving in the overheated engine protection
operating mode, to avoid engine damage, allow
the engine to cool before attempting any repair.
The engine oil will be severely degraded. Repair
the cause of coolant loss, change the oil and reset
the oil life monitor. See ªEngine Oilº in the Index.
If Steam Is Coming From Your Engine
CAUTION:
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay away
from the engine if you see or hear steam coming
from it. Just turn it off and get everyone away
from the vehicle until it cools down. Wait until
there is no sign of steam or coolant before you
open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch fire. You or
others could be badly burned. Stop your engine
if it overheats, and get out of the vehicle until the
engine is cool. See ªOverheated Engine Protection
Operating Modeº in the Index.

6-16 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
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. Use engine oil meeting the
GM Standard GM4718M.
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 message appears. Remember to reset the
system whenever the oil is changed.
How to Reset the Change Oil Soon Message
To reset the CHANGE OIL SOON message after an oil
change, do the following:
1. Turn the ignition to ON and with the engine off.
2. Press the TRIP button so the OIL LIFE percentage
is displayed.
3. Press RESET and hold for two seconds. OIL LIFE
REMAIN 100% will appear.
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 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.

6-49 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.
Each new wheel should have the same load
-carrying
capacity, diameter, width, offset and be mounted the
same way as the one it replaces.
If you need to replace any of your wheels, wheel bolts
or wheel nuts, replace them only with new GM original
equipment parts. This way, you will be sure to have the
right wheel, wheel bolts and wheel nuts for your vehicle.
CAUTION:
Using the wrong replacement wheels, wheel bolts
or wheel nuts on your vehicle can be dangerous.
It could affect the braking and handling of your
vehicle, make your tires lose air and make you
lose control. You could have a collision in which
you or others could be injured. Always use the
correct wheel, wheel bolts and wheel nuts
for replacement.
NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper
height, vehicle ground clearance and tire
clearance to the body and chassis.
