I’ve searched the owner’s manual and the warranty and service guide. I can’t find anything that shows where you can change the date or mileage of the oil maintenance reminder.
I found 3 videos that show how to reset the oil maintenance reminder. All 3 show reset data only (no additional choices) .

This is 1 of the videos.

My guess is that the maintenance minder is just a value entered by the dealer based on how often they think you should come in for an oil change. For example, here in Canada, while it says 1 yr or 16,000km (roughly 10k miles) in the manual as well, I believe there is a section in there for "Severe" Maintenance schedules, which all dealers love to set for our Canadian cars. That means every 6 months/8,000 km (5,000 miles), the oil change reminder will pop up.
The reminder intervals can be manually changed in the Maintenance settings on the Nav screen.

It's done on the nav screen - maybe different models are different, mine's an F-Sport with the larger screen, enter the main menu there and follow as I said.
