Any settings changed under the settings menu will not save if you just back out. The 'save' button must be hit 1st. Is it possible that's the issue? Try it one more time to verify. If not that, then don't know.
I recently changed the oil in my 2018 PEHV Clarity (6,000 miles). I have attempted to reset the maintenance minder by following the procedure specified on page 142 of the owners manual and nothing happens. Anyone have any suggestions or recommendations as to how to accomplish the reset?
