None of the levels you mention (until Level 5) operate any differently from this feature. In any of those cases, if I replace the missing parts, I get my heated seats. I would be ticked off if Level 2 had physically integrated seat warmers had some protection people could not work around so they had to cut out and replace the seat warmers. Level 5, and this case, all I'm doing is adding the missing component. A flag or something.
