Buick Regal: Engine Oil Life System
						
			The engine oil life system calculates
engine oil life based on vehicle use
and displays the CHANGE ENGINE
OIL SOON message when it is time
to change the engine oil and filter.
The oil life system should be reset
to 100% only following an oil
change.
Resetting the Oil Life System
1. Using the DIC controls on the
right side of the steering wheel,
display REMAINING OIL LIFE on the DIC. 
When remaining oil life is low,
the CHANGE ENGINE OIL
SOON message will appear on
the display.
2. Press 
 on the DIC controls
and hold down for a few
seconds to clear the CHANGE
ENGINE OIL SOON message
and reset the oil life at 100%.
Be careful not to reset the oil
life display accidentally at any
time other than after the oil is
changed. It cannot be reset
accurately until the next oil
change.
