When MDS comes on in my 09 I can hear and feel it switch over..at the same time the fuel saving light comes on..every time..doesnt matter the temps..even at -35 and with a cold motor it will come on. One thing I dont notice is the fuel usage meter changing when it switches..technically it should drop from 18mpg in 8cyl mode to 14mpg? in MDS?
