Once again, the person I was replying to was talking about the maintenance notification on their car. Not some ad for satellite radio or some other thing, a maintenance notification. It's scheduled to go off at the scheduled maintenance interval. It's not an ad. Any knowledgeable individual can clear it if they did their maintenance by the book. It's a reminder to go look at the book and do the scheduled maintenance or pay someone else to do it for you, whether that be the dealer or any other knowledgeable shop. Having it continue to go off indicates one didn't bother doing the scheduled maintenance on it. They're continuing to operate their car probably in public spaces while ignoring the maintenance.
