I'm not speaking about any one code in particular. What I am saying is, if for some reason you got into an accident, I would definitely not put it past the insurance company to plug their computer into the car, see that defaults are changed, and deny you your claim. "Mr. Smith, we regret to inform you that you're out of luck because your car did not have the proper warning displayed upon startup on the display screen". "What's that have to do with someone hitting me at 25MPH?" "It doesn't matter, it's been changed from factory default. Go buy a Hyundai".
