It's the one that reminds you to change the oil, *not* Check Engine. How do I make it turn off? (Besides waiting 2 minutes)



I pulled out the rubber plug on the face of the instrument panel. I got a skinny pen refill so I could poke the button inside. I've tried:



- Single poke with the engine running.



- Single poke with the key on, engine not running.



- Single poke with key off.



- Holding the button for 20 seconds, engine running.



- Holding the button for 20 seconds, engine not running.



- Holding the button for 20 seconds, key off.



- Holding the button while turning key to "on".



- Holding the button while passing through "on" and starting engine.



- Poking button 5,327 times with engine running, while cursing loudly. I'm out of ideas.
