Good morning Dave, and thanks for the reply🙂
If I pull down on the little shifter bar, it goes into Sport mode. But it's always been like that, but never had that arrowhead - the arrowhead now stays whether in "D" or "S" mode. When my husband got into the car to drive it, he immediately noticed the addition of the arrowhead as well.
I did find this (see screenshot) while Googling, but as I mentioned previously, it was never there before! Wondering what I did to make that arrowhead appear.
