I do have a question about how and when the MDS mode kicks in. I have noticed that the Fuel Saver light only comes ON when the shifter is in D. If you are in TOW/HAUL mode or in "manual" mode (Tiptronic) there is no Fuel Saver light. Does that mean the MDS is only active in D, or is just the light that comes ON only in D?
MDS is only active when in D. Also for those of us that don't have the fuel saver light, just watch your rpms drop once you get to a steady speed. I have the 3.21's and at 65mph I'm running about 1500rpms
