tape is covered on the airbag emblem from the manufacturer to prevent scratches when they install it. my guess when it was installed in the car the tape was never removed and got baked in the sun ? Thats my guess.
Only you can answer that one. Of course you can remove it, but now that it has been there for a period of time and whether or not it takes some of the colors with it, who knows? Me, I would probably try it, but that's me.
