The ECON light on the dash is controlled by a button in the end of the shift leaver. I use the ECON mode 99% of the time. The Allison MH2500 has two shift patterns programmed in it. When the ECON light is off, your shift points will be much higher and therefore use more fuel. When in ECON, the shift points will be lower to conserve fuel. If you push the accelerator past midpoint on while in ECON mode, it will automatically revert back to the non-ECON mode and shift at the higher points.

You need to try both modes to see which one you like best. I wish they had given an ECON off light rather that being illuminated when it is engaged since I drive most of the time with the ECON mode on. I really tire of seeing the light on at night.
