TNC is on a distinguished road

EVIC or not, you have the same functioning MDS on your model truck. When the display that has the "ECO" symbol is scrolled to, the "ON" symbol means your MDS is engage...4-cylinder mode. The reference to "Fuel Economy" in the EVIC display is just the same thing for a different display method. You have MDS. Most people can hear or feel the MDS kick in and out, though I'd agree that it's a bit harder at highway speeds. Yes, it goes off fairly easily on slight grades or even moderate head winds.
