Yes it just goes through its typical progression down to 0%, as if you were driving it to rack up the miles. It just happens in a way that it is now based on time too. Only a Honda engineer would know for sure how it works and now that I'm typing this, I'm curious. Let's say that the mileage target for my vehicle is 7500 miles (if I drove 7500 miles in 1 month, the MM would have gotten down to zero - I'm using hyperbolic examples here to make the point). So if I've only driven 2000 miles after 10 months, the MM certainly isn't still at 70%...it is lower because the MM also counts down with time. Maybe it's at 15% let's say as there is only 2 months left for it to get itself down to 0%. If I still don't drive another mile at that point, at EXACTLY 12 months it will click to 0%. BUT if at that 2000 miles and 15%, all of a sudden I start driving like crazy and put 4000 miles on it in a week, will it tick down to zero quickly (because 15% of 7500 miles is only like 1100 miles) or will it just sit at 15% because even as I'm building back miles driven, that number of miles (now 6000) is still below the 15% of theoretical 7500 miles in this period? Hope I'm explaining myself.
