the fuel saver indicator light will advise people when they have reached the economy target zone and fuel-saver mode target range.
from everything that i read, if you see the ECO mode indicator displayed, you are in MDS mode
so from what i can tell from reading, not personal knowledge, the ECO mode & MDS may be the same thing.
the Fuel Saver Light is a bit different than ECO mode, although the ECO mode & the Fuel Saver Indicator Light may be on at the same time, under certain conditions
The "Eco-mode" message is clearly tied more to throttle position, rpm, and engine temperature, than it is to "driving in the most economical fashion".
You can drive economically like granny up long inclines, but it won't come on.
You can let off the gas pedal and start braking going downhill, or to stop for a traffic light, and "Eco" comes on. Both these examples are negatives for good MPG.
So logically that's not what it is.
I wish I could view Chrysler's code logic on this indicator display, so we could put this debate to rest.
