When the system has calculated that oil life has 
been diminished, it will indicate that an oil change is
necessary. A CHANGE OIL SOON 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 
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 Change Oil Soon Message
The GM Oil Life System
t 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
OIL SOON message being turned on, reset the system.
To reset the CHANGE OIL SOON message after an oil
change, do the following:
1. Turn the ignition to ON, with the engine off.
2. Press the TRIP button so the OIL LIFE percentage 
is displayed.
3. Press RESET and hold for two seconds. OIL LIFE
REMAIN 100% will appear.
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 throw away 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.
