4 STEPS Mercury Mountaineer 2000-2005 Oil life Reset

Good day friends, this is a simple tutorial on how to reset the Oil change  reminder indicator in  Mercury Mountaineer for the 2000-2001-2002-2003-2004-2005 year model.

CHANGE OIL SOON/OIL CHANGE REQUIRED. Displayed when the engine oil life remaining is 5 percent or less. When oil life left is between 5% and 0%, the CHANGE OIL SOON message will be displayed. When oil life left reaches 0%, the OIL CHANGE REQUIRED message will be displayed. An oil change is required whenever indicated by the message center. USE ONLY RECOMMENDED ENGINE OILS. To reset the oil monitoring system to 100% after each oil change [approximately 8 000 km (5 000 miles) or 180 days] perform the following:


  • Gear to the park position then turn the ignition On.


  • Press the SETUP button until the PRESS RESET AT OIL CHANGE is displayed.

  • Oil reset is complete. Turn off the ignition then start the engine to verify if the maintenance reminder is successfully reset.

That is the most effective way to reset the oil life service maintenance reminder indicator for Mercury Mountaineer from the year 2000-2005.
