just posting i have found out from someone else, where the switch is.its on the display between the clocks which you have to use the stick on the left side of streering wheel. goto menus and press set scroll down to ESP and press set. yellow esp light will come on to confirm the tracion control is switched off.. this is resetted every time the car is switched off !!! and you must then do it over again to switch it back off
hope this helps someone else out...
