DVD Distortion
You may experience video distortion when operating
cellular phones, scanners, CB radios, Global Position
Systems (GPS)*, two-way radios, mobile fax, or
walkie talkies.
It may be necessary to turn off the DVD player when
operating one of these devices in or near the vehicle.
*Excludes the OnStar
žSystem.
Radio Reception
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.
FM
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.
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 are not, 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 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 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.
3-98

The broken tape detection feature of your cassette tape
player may identify the cleaning cassette as a
damaged tape, in error. To prevent the cleaning cassette
from being ejected, use the following steps:
1. Turn the ignition on.
2. Turn the radio off.
3. Press and hold the TAPE CD button for ®ve
seconds. READY will appear on the display and a
cassette symbol will ¯ash for ®ve seconds.
4. Insert the scrubbing action cleaning cassette.
5. Eject the cleaning cassette after the manufacturer's
recommended cleaning time.
After the cleaning cassette is ejected, the broken tape
detection feature will be 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 EJT
button for ®ve seconds to reset the CLEAN indicator.
The radio will display CLEANED 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 CDs and DVDs
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.

Notice:Use only engine oil identi®ed as meeting
GM Standard GM6094M and showing the American
Petroleum Institute Certi®ed For Gasoline Engines
starburst symbol. Failure to use the recommended
oil can result in engine damage not covered by
your warranty.
GM Goodwrench
žoil meets all the requirements for
your vehicle.
If you are in an area of extreme cold, where the
temperature falls below-20ÉF (-29ÉC), it is
recommended that you use 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
Do not add anything to your oil. The recommended oils
with the starburst symbol meet GM Standard GM6094M
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 ®lter. 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 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 ®lter must be changed at least once a year
and at this time the system must be reset. Your dealer
has GM-trained people who will perform this work using
genuine GM parts and reset the system. 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.
5-16

How to Reset the Change Engine Oil
Message
The GM Oil Life System calculates when to change your
engine oil and ®lter 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 being turned on, reset the system.
1. With the ignition key in RUN but the engine off,
repeatedly push the trip/reset button until OIL is
displayed on the Driver Information Center (DIC).
2. Once OIL is displayed, push and hold the trip/reset
button for ®ve seconds. The number will disappear
and be replaced by 100 (indicating 100% oil life
remaining).
3. Turn the key to OFF.
If the CHANGE ENGINE OIL message comes back on
when you start your vehicle, the engine oil life system
has not reset. Repeat the procedure.
What to Do with Used Oil
Used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer.
Do not 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 dispose
of 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 threat to the environment. If you
change your own oil, be sure to drain all the oil from
the ®lter before disposal. Never 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.

{CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Do not spill coolant on a hot engine.
Occasionally check the coolant level in the radiator.
For information on how to add coolant to the radiator,
see
Cooling System on page 5-28.
Radiator Pressure Cap
Notice:The radiator cap on your vehicle is a
pressure-type cap and must be tightly installed to
prevent coolant loss and possible engine damage
from overheating. Be sure the arrows on the cap line
up with the over¯ow tube on the radiator ®ller neck.
The radiator pressure cap is located at the front of the
engine compartment on the passenger's side of the
vehicle. See
Engine Compartment Overview on
page 5-12for more information on location.
Engine Overheating
You will ®nd an engine coolant temperature gage on
your vehicle's instrument panel cluster. SeeEngine
Coolant Temperature Gage on page 3-48. You
also have an engine coolant temperature warning
message on your instrument panel. See
Engine Coolant
Temperature Warning Message on page 3-54.
Overheated Engine Protection
Operating Mode
This emergency operating mode allows your vehicle to
be driven to a safe place in an emergency situation.
If an overheated engine condition exists, an overheat
protection mode which alternates ®ring groups of
cylinders helps prevent engine damage. In this mode,
you will notice a signi®cant loss in power and engine
performance. The temperature gage will indicate
an overheat condition exists. Driving extended
miles (km) and/or towing a trailer in the overheat
protection mode should be avoided.
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 system. See
Engine Oil on page 5-13.

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 or tire chain
clearance to the body and chassis.

Publications Ordering Information on page 7-12.
Owner Checks and Services on page 6-9tells you what
should be checked, when to check it and what you can
easily do to help keep your vehicle in good condition.
The proper replacement parts, ¯uids and lubricants to
use are listed in
Recommended Fluids and Lubricants
on page 6-12andNormal Maintenance Replacement
Parts on page 6-14. When your vehicle is serviced,
make sure these are used. All parts should be replaced
and all necessary repairs done before you or anyone
else drives the vehicle. We recommend the use of
genuine GM parts.
Scheduled Maintenance
When the change engine oil message comes on, it
means that service is required for your vehicle. Have your
vehicle serviced as soon as possible within the next 600
miles (1 000 km). It is possible that, if you are driving
under the best conditions, the engine oil life system may
not indicate that vehicle service is necessary for over a
year. However, your engine oil and ®lter must be changed
at least once a year and at this time the system must be
reset. Your GM Goodwrench dealer has GM-trained
service technicians who will perform this work using
genuine GM parts and reset the system.If the engine oil life system is ever reset accidentally,
you must service your vehicle within 3,000 miles
(5 000 km) since your last service. Remember to reset
the oil life system whenever the oil is changed. See
Engine Oil on page 5-13for information on the Engine
Oil Life System and resetting the system.
When the change engine oil message appears, certain
services, checks and inspections are required.
Required services are described in the following for
ªMaintenanceIº and ªMaintenanceII.º Generally,
it is recommended that your ®rst service be
MaintenanceI, your second service be MaintenanceII
and that you alternate MaintenanceIand MaintenanceII
thereafter. However, in some cases, MaintenanceII
may be required more often.
MaintenanceIÐ Use MaintenanceIif the change
engine oil message comes on within ten months since
vehicle was purchased or MaintenanceIIwas
performed.
MaintenanceIIÐ Use MaintenanceIIif the previous
service performed was MaintenanceI. Always use
MaintenanceIIwhenever the message comes on ten
months or more since the last service or if the message
has not come on at all for one year.
