Few issues have troubled technicians more than the infamous “Change oil soon light.” We have even had quick lube shops send customers to me at the dealership to shut off this light. Yes, the engineer that designed this system most certainly had flunked out of the “User Friendly” semester of college. The most common problem is between step 1 and 2 of the owner’s manual. The natural tendency is that when we scroll through the menu to the “oil life XX%” mode, we lift our finger. This is where most go wrong. Once the “oil life XX%” comes up on the menu, do NOT lift from depressing the button- just hold for 5 seconds until the “Reset for new oil life” comes up. Again, do not lift your finger.

Just had to do this for my father's 2010 Marquis. It's mind numbing trying to figure the sequence.. Without looking at the manual, I nailed it down to..... #1, turn ignition to Run, no need to start. #2, Press the reset button when the "Oil Change Needed" message comes up. (otherwise, you can't proceed.) #3, Press Set-Up #4, Press Select Once, the message "Oil Life xx% Press Reset for New Oil" comes up. #5, Press and HOLD the Reset button, until the message "Washer fluid OK." comes up. (the 5 needed seconds.) #6, release and let it finish the system check.. turn ignition OFF. Mind you, as soon as you see the message in step 4, you have almost 1-2 seconds to get over to the reset switch. It took me a few attempts.. He noticed, the alert message came up in less than 5000 miles, but we'll see now.. He's still getting the regularly scheduled changes done by the dealer.

I don't know how to reset the oil change sensor and can not find an answer in the owner's manual.
