holding the tc button down for 5 seconds will disable all the tc features (roll stability, trailer sway, tc) up until 25mph, i think that's the speed (it's explained in the manual). Pressing it once turns tc off but leaves roll stability, trailer sway on. I've seen good responses from allowing tc to stay on in both 2wd and 4x4. pressing the button once usually lets you spin the tires more if needed.
