yeah was playing with some features and put in an oil change in 100 miles...7 days later bam oil change required but it just got serviced so how can i reset it or take it off/
You need to turn the key to the off position and push or hold the reset "ODO" button and then while your pressing the button turn the key to ignition on (you dont have to start the engine) and wait until the light goes away to release the button.
Before that, you need to make sure that the ODO is showing the ODO miles and not the A/B trip display. Its a bit confusing at first, but you'll get the hang of it
It's also in the Owner's Manual. Not the easiest topic to find, but its there.
