What To Do With Used Oil - GMC 2010 Sierra Owner's Manual

If the system is ever reset accidentally, the oil must be
changed at 5 000 km (3,000 miles) since the 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 the engine oil and filter based on vehicle use.
Whenever the oil is changed, reset the system so it can
calculate when the next oil change is required. If a
situation occurs where the oil is changed prior to a
CHANGE ENGINE OIL SOON message coming on,
reset the system.
Always reset the engine oil life to 100% after every oil
change. It will not reset itself. To reset the Engine Oil
Life System on most vehicles:
1. Display the OIL LIFE REMAINING on the DIC.
If the vehicle does not have DIC buttons, the
vehicle must be in P (Park) to access this display.
See DIC Operation and Displays (With DIC
Buttons) on page 4 50 or DIC Operation and
Displays (Without DIC Buttons) on page 4 59.
2. Press and hold the SET/RESET button on the DIC,
or the trip odometer reset stem if the vehicle does
not have DIC buttons, for more than five seconds.
The oil life will change to 100%.
On all vehicles, the Engine Oil Life System can be reset
as follows:
1. Turn the ignition to ON/RUN with the engine off
2. Fully press the accelerator pedal slowly three times
within five seconds.
3. Display the OIL LIFE REMAINING on the DIC.
If the display shows 100%, the system is reset.
See DIC Operation and Displays (With DIC
Buttons) on page 4 50 or DIC Operation and
Displays (Without DIC Buttons) on page 4 59.
If the vehicle has a CHANGE ENGINE OIL SOON
message and it comes back on when the vehicle is
started and/or the OIL LIFE REMAINING is near 0%,
the Engine Oil Life System has not reset. Repeat the
procedure.

What to Do with Used Oil

Used engine oil contains certain elements that can 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.
