Not sure how the earlier models read MDS engagement. I don't have EVIC, so the "ECO" symbol in my dash readout has an "ON" symbol when MDS kicks in. If I'm driving in a manner suited to the MDS coming on, it seems to always come on regardless of the temp. Regardless of the constantly changing "ON" light for MDS, I think one can easily tell when it comes on and off if you're in tune with how your vehicle responds. I don't find it annoying, but I can almost always tell when MDS is in operation...except perhaps some highway scenarios at speed where the MDS operation is pretty well seamless.
mine also goes on when the engine is cool, even if it was just started,.., with my muffler its easy to hear it on,.. and also have the eco light
