Yellow circle with a right-side up triangle in the lower right of the tach gauge is for the PSM. The PSM button is the bottom right button on the console. I have accidently bumped the PSM off (which lights it up) when fishing for my cell phone or tape measure in the pocket right in front of the gear shift. If it's this simple, just poke the button again and its pilot light along with the circle with the triangle should go off. Not a good idea to drive with the PSM off in everyday driving -- that's why there is dramatic warning light. If the button won't turn it the warning light, definitely get it checked out.
