Mrs. Noah has a Honda minivan as a DD. After about 10 months of ownership, she turned to me one day (while I happened to be driving it) and asked, "What's that "echo" thingie on the dashboard that comes on from time to time?"

"Huh? What echo thingie?" I replied.
"That," she said as she pointed to the little "ECO" light that lit up.
It was the "Economy" light that indicates cylinder deactivation for fuel savings. I happened to be coasting down the street at the time.

Fortunately it wasn't anything serious, but it makes me wonder: when a light goes on on the dashboard, why not try to look it up to figure out what's wrong (or what it's telling you) as opposed to forging ahead?
