DIC Warnings and Messages
Messages are displayed on the DIC to notify the
driver that the status of the vehicle has changed
and that some action may be needed by the driver
to correct the condition. Multiple messages may
appear one after another.
Some messages may not require immediate
action. Press any of the DIC buttons on the
steering wheel or the trip odometer reset stem
located on the instrument panel cluster to
acknowledge that you received the messages and
to clear them from the display.
Some messages cannot be cleared from the
display because they are more urgent. These
messages require action before they can be
removed from the DIC display. Take any messages
that appear on the display seriously and remember
that clearing the messages will only make the
messages disappear, not correct the problem.
The following are the possible messages that can
be displayed and some information about them.
BATTERY NOT CHARGING
This message displays if the battery is not
charging during operation. Driving with this
problem could drain the battery. Have the electrical
system checked as soon as possible by your
dealer. SeeCharging System Light on page 209

information. Press any of the DIC buttons, or the
trip stem, to acknowledge this message and
clear it from the DIC display.

A non-scrubbing action, wet-type cleaner which
uses a cassette with a fabric belt to clean the tape
head can be used. 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 the player is cleaned, press and hold the
eject button for ve seconds to reset the CLEAN
indicator. The radio will display --- or 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
the tape player is serviced.Care of Your CDs and DVDs
Handle CDs and DVDs carefully. Store them in
their original cases or other protective cases and
away from direct sunlight and dust. The CD
and DVD player scans the bottom surface of the
disc. If the surface of a CD or DVD is damaged,
such as cracked, broken, or scratched, the CD or
DVD will not play properly or not at all. If the
surface of a CD or DVD is soiled, take a soft, lint
free cloth or dampen a clean, soft cloth in a
mild, neutral detergent solution mixed with water,
and clean it. Make sure the wiping process
starts from the center to the edge. If a dampened
cloth was used to clean the disc, dry it with a
dry cotton cloth.
Do not touch the bottom side of a CD or DVD
while handling it; this could damage the surface.
Pick up CDs or DVDs by grasping the outer edges
or the edge of the hole and the outer edge.

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 0W-30 oil. Both will
provide easier cold starting and better protection
for the engine at extremely low temperatures.
Engine Oil Additives
Do not add anything to the oil. The recommended
oils with the starburst symbol that meet GM
Standard GM6094M are all you will 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.
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 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 message
being turned on, reset the system.
To reset the CHANGE ENGINE OIL message,
see “Engine Oil Life System” underDIC Operation
and Displays on page 222for vehicles that
have the DIC, or do the following:
1. Turn the ignition key to RUN with the engine off.
2. Fully press and release the accelerator pedal
slowly three times within ve seconds.
If the OIL LIFE RESET message ashes for
10 seconds, the system is resetting.
3. Turn the key to LOCK.
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.
If it still does not reset, see your dealer for service.
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.
