Not the sport mode button, press and hold your traction control (far right button) and this will put your ESP stability control to full off. Pressing it once quickly will turn off traction control only. Car must be stopped or moving less than 5 mph for this to work and you will get confirmation on your EVIC that it is off. This is the closest we can get to the SRT track mode. The sport mode button on other than SRT affects the automatic transmission only.
