I was just thinking there may be a way to change from on to off with a setting. Like turning the seat belt chime off by turning on the key and fastening and unfastening the seat belt 3 times or pressing both fob buttons and turning on the key to reinitialize the fob. There are several cars that you program key transponders by pressing gas 4 times and fastening the seat belt twice then pressing the brake twice stuff like that. The XF's are pretty "deep" when it comes to hidden settings and controls. I would rather have the traction control off with the light off and if I turn it on the light would go on instead. If I have to suddenly get out of the way or something I don't want the engine cutting out with the traction control.
