I have a 2016 and, if you want to turn it off completely, you have to hold the button down while your foot is on the brake and the car is in park until it tells you the Adavnce Track is disabled.
I have a performance package but I don’t see why the traction control would be much different other than the sport mode which is available on the performance package.
Only PP equipped cars can completely turn off all traction devices.
