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 in the Driver Information Center (DIC) being
turned on, reset the system.
After the oil has been changed, the CHANGE ENGINE
OIL message must be reset. To reset the message,
do the following:
1. Turn the key to the “ON” position without starting
the engine.
2. Press the INFO button on the Driver Information
Center (DIC) until ENGINE OIL LIFE is displayed.
3. Press and hold the INFO RESET button until 100%
ENGINE OIL LIFE is displayed. This resets the oil
life indicator.
The percentage of oil life remaining may be checked at
any time by pressing the INFO button until ENGINE
OIL LIFE is displayed on the DIC. For more information
on the oil life indicator, see
Oil Life Indicator on
page 3-79.
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.
