DVD Distortion
You may experience video distortion when operating
cellular phones, scanners, CB radios, Global Position
Systems (GPS)*, two-way radios, mobile fax, or
wal kie 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@ System.
Understanding 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
if you ever get it.
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 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 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
cieaning casseiie wirn pads wnicn scrub tne tape
head as the hubs of the cleaner cassette turn.
The recommended cleaning cassette is available
through your dealership.
3-1 03

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 five
seconds. READY will appear on the display and
a cassette symbol will flash for five 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 five 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.
Care of Your CD and DVD 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.

As in the chart shown previously, SAE 5W-30 is the
only viscosity grade recommended for your vehicle.
You should look for and use only oils which have the
API Starburst symbol and which are also identified
as SAE 5W-30. If you cannot find such SAE 5W-30 oils,
you can use an SAE
1OW-30 oil which has the
API Starburst symbol,
if it's going to be 0°F (-18°C)
or above. Do not use other viscosity grade oils, such as
SAE 1OW-40 or SAE 20W-50 under any conditions.
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 of extreme cold, where the
temperature falls below -20°F (-29"C), it is
recommended that you use either an SAE 5W-30
synthetic oil or an SAE OW-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 pe;formance and engifie prs:ection.
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 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

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.

How to Reset the Change Engine
Oil Message
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
being turned on, reset the system.
1. With the ignition key in RUN but the engine off,
repeatedly push the tripheset button until OIL is
displayed on the Driver Information Center (DIC).
2. Once OIL is displayed, push and hold the tripheset
button for five 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,
the engine oil life monitor 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.
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 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 filter 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.

Radiator Pressure Cap
Notice: Your radiator cap 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
overflow tube on the radiator filler 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 5-72 for more information on location.
Engine Overheating
You will find an engine coolant temperature gage on
your vehicle’s instrument panel cluster. See
Engine
Coolant Temperature Gage
on page 3-47. You also
have an engine coolant temperature warning message
on your instrument panel. See
Engine Coolant
Temperature Warning Message
on page 3-53.
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 firing groups of
cylinders helps prevent engine damage.
In this mode,
you will notice a significant
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” in
the Index.

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.
Each new wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted
the same way as the one it replaces.
