Here is a bunch of pics that speak a 1000 words LOL... the blurry one shows what the M button controls...i obviously dont have a steady hand with my stupid cell phone cam... but...anyway...it says EDC, DSC (Dynamic Stability Control), Power, Servotronic (steering). The other pics show the options within each area. You also have some buttons to control these individualy if you don't want to use (or have) the M button.
