Handling the DVD Map Disc
When handling the DVD map disc, be careful of the
following:
Handle the disc very carefully to avoid
contamination or aws. Signals may not read out
properly if the disc gets contaminated or awed.
If the disc gets soiled, use a soft cloth to gently wipe
it out from the center of the disc to the outside.
Do not use photographic record cleaner, solvents,
or other cleaners.
Do not use the disc to rest on while writing or
drawing using any writing utensil or attach a seal
to any of the sides or the disc.
Do not keep the disc in direct sunlight, high
temperatures, or humidity.
After using the disc, place it back into the
original case.

Of course, traction is reduced when water, snow, ice,
gravel, or other material is on the road. For safety,
you will want to slow down and adjust your driving to
these conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
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 Antilock Brake System (ABS) helps
avoid only the braking skid.Racing or Other Competitive
Driving (XLR-V)
See your warranty book before using your vehicle for
racing or other competitive driving.
Notice:If you use your vehicle for racing or other
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 racing or other competitive driving and
keep the level at or near 2 quarts (2 L) above 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 6-16.
After the competitive driving, remove excess oil
so that the level on the dipstick is not above
the upper mark that shows the proper operating
range.

Oils meeting these
requirements should have
the starburst symbol on
the container. This symbol
indicates that the oil
has been certied by the
American Petroleum
Institute (API).
Look for this on the oil container, and use only those
oils that are identied as meeting GM Standard
GM4718M and have the starburst symbol on the front of
the oil container.
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 Standard
GM4718M 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 XLR-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.When the system has calculated that oil life has been
diminished, it will indicate that an oil change is
necessary. A CHANGE OIL NOW message in the DIC
will come on. SeeDIC Warnings and Messages on
page 3-63. Change the 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
might not indicate that an oil change is necessary for
over a year. However, the engine oil and lter must be
changed at least once a year and at this time the
system must be reset. Your dealer/retailer has trained
service people who will perform this work using genuine
parts and reset the system. It is also important to
check the oil regularly and keep it at the proper level.
If the system is ever reset accidentally, you must change
the 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.
