How to Reset the Oil Life on a Lincoln Navigator

Steps from the 2010 Lincoln Navigator owner's manual.

Press and release the SETUP button until the message center shows "OIL LIFE XXX% HOLD RESET = NEW".
Press and hold the RESET button for two seconds.
Release the RESET button to set the oil life back to 100%.

Reset after each oil change, approximately 7,500 miles (12,000 km) or 12 months.
To use a different start value, after "OIL LIFE SET TO XXX%" appears, release and press RESET; each press lowers it by 10%.
