I'm interested in this as well. With my IS300, I was able to find some vinyl "Lexus" stickers that fit perfectly over those warning labels. I got those years ago and can't find any that would fit over the CT's warning stickers. I need to look again . . . haven't checked for a couple of months. There are tons message board posts around the net with instructions on how to get those off (as I'm sure you are aware), but I'm scared to mess with those things. Personally, I'd just look to cover them up.
