Using the Six-Disc CD Changer
The CD player can play the smaller 3 inch (8 cm)
single CDs with an adapter ring. Full-size CDs
and the smaller CDs are loaded in the same
manner.
If playing a CD-R, the sound quality can be
reduced due to CD-R quality, the method of
recording, the quality of the music that has been
recorded, and the way the CD-R has been
handled. There can be an increase in skipping,difficulty in nding tracks, and/or difficulty in
loading and ejecting. If these problems occur,
check the bottom surface of the CD. If the surface
of the CD is damaged, such as cracked, broken,
or scratched, the CD will not play properly.
If the surface of the CD is soiled, seeCare of
Your CDs on page 313for more information.
If there is no apparent damage, try a known
good CD.
Do not add any label to a CD, it could get caught
in the CD player. If a CD is recorded on a
personal computer and a description label is
needed, try labeling the top of the recorded CD
with a marking pen.
Notice:If a label is added to a CD, or more
than one CD is inserted into the slot at a time,
or an attempt is made to play scratched or
damaged CDs, the CD player could be
damaged. While using the CD player, use only
CDs in good condition without any label,
load one CD at a time, and keep the CD player
and the loading slot free of foreign materials,
liquids, and debris.
If an error displays, see “CD Messages” later in
this section.

While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration, or
braking, including reducing vehicle speed by
shifting to a lower gear. Any sudden changes could
cause the tires to slide. You may not realize the
surface is slippery until your vehicle is skidding.
Learn to recognize warning clues — such as
enough water, ice, or packed snow on the road to
make a mirrored surface — and slow down when
you have any doubt.
Remember: Any Anti-Lock Brake System (ABS)
helps avoid only the braking skid.
Competitive Driving
See your warranty book before using your vehicle
for competitive driving.
Notice:If you use your vehicle for competitive
driving, the engine may use more oil than it
would with normal use. Low oil levels can
damage the engine. Be sure to check the oil
level often during competitive driving and keep
the level at or near the upper mark that
shows the proper operating range on the
engine oil dipstick. For information on how to
add oil, seeEngine Oil on page 380.
Driving at Night
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to
be impaired — by alcohol or drugs, with night
vision problems, or by fatigue.
Here are some tips on night driving.
Drive defensively.
Do not drink and drive.
Adjust the inside rearview mirror to reduce the
glare from headlamps behind you.
Since you cannot see as well, you may need
to slow down and keep more space between
you and other vehicles.
Slow down, especially on higher speed roads.
Your vehicle’s headlamps can light up only so
much road ahead.
In remote areas, watch for animals.
If you are tired, pull off the road in a safe
place and rest.

Your vehicle’s engine is lled at the factory with a
Mobil 1®synthetic oil, which meets all
requirements for your vehicle.
Substitute Engine Oil: When adding oil to maintain
engine oil level, oil meeting GM Standard
GM4718M may not be available. You can add
substitute oil designated SAE 5W-30 with
the starburst symbol at all temperatures. Substitute
oil not meeting GM Standard GM4718M should
not be used for an oil change.
Engine Oil Additives
Do not add anything to the oil. The recommended
oils with the starburst symbol that meet GM
standards are all you need for good performance
and engine protection.
Engine Oil Life System
When to Change Engine Oil
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.
Notice:If your vehicle is an STS-V model, the
engine uses a special oil lter. The use of
any other engine oil lter could lead to lter
failure and result in severe engine damage.
Damage caused by use of the wrong engine oil
lter would not be covered by your new
vehicle warranty.
383

When the system has calculated that oil life has
been diminished, it will indicate that an oil change is
necessary. A CHANGE ENGINE OIL SOON
message in the DIC will come on. SeeDIC
Warnings and Messages on page 264. Change
your oil 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 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 service 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.How to Reset the Engine Oil Life
System
The Engine 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 SOON message in the DIC being turned on,
reset the system.
After the oil has been changed, the CHANGE
ENGINE OIL SOON message must be reset. To
reset the message use the following procedure:
1. Press the up or down arrow to scroll the DIC
to show OIL LIFE.
2. Once the XXX% ENGINE OIL LIFE menu item
is highlighted, press and hold the RESET
button until the percentage shows 100%.
If the percentage does not return to 100% or if
the CHANGE ENGINE OIL SOON 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.
Supercharger Oil
Because they are technically qualied and have
the proper tools, you should have your dealer
perform this maintenance.
When to Check
SeeAdditional Required Services on page 508for
when the oil level should be checked.
What Kind of Oil to Use
Use only the recommended supercharger oil. See
Recommended Fluids and Lubricants on
page 516.

Engine Air Cleaner/Filter
The engine air cleaner/lter is in the engine
compartment on the driver’s side of the vehicle,
near the front. SeeEngine Compartment Overview
on page 373for more information on locating
the air cleaner/lter.
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/lter at the MaintenanceII
intervals and replace it at the rst oil change
after each 50,000 mile (83 000 km) interval. See
Scheduled Maintenance on page 505for more
information. If you are driving in dusty/dirty
conditions, inspect the lter at each engine
oil change.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/lter remove the lter
from the vehicle and lightly shake the lter to
release loose dust and dirt. If the lter remains
caked with dirt, a new lter is required.
To inspect or replace the lter in the 3.6L V6 or
4.6L V8 engines, do the following:
1. Remove the two screws located on the top of
the cover.
2. Disconnect the coolant recovery hose so that
it is not going across the top of the engine air
cleaner/lter.
