2019 Cadillac XT5. There is a button just to the left of the CUE screen. It's a orange "P" with a symbol similar to》after. It automatically turns on when I start the car. I can turn it off, but since I don't know what it I'd, I'm afraid to! Can anyone tell me what this P》stands for? And no, it's not my parking brake. I cannot find it anywhere in the manual!

That's the button you press when you want the automatic parallel parking system to facilitate parking the car
