I tried searching MDS and can't get anything to come up and Ram doesn't seem to give out to much info on how it works. Here's my questions: I had a 2014 Laramie CC 4x2 that I bought new. Fast forward and I know have a brand new 16 Sport CC 4x4. I have just over 500 miles on it and the MDS has yet to come on. In my old Laramie as long as you didn't go over 78, it would turn on when cruising. My new Sport has yet to show me that it is working. Is there a way to turn it on or off? Does the truck have to hit a certain mileage before it even starts working?

There won't be any on dash/screen indication of when MDS is being used so you may not be noticing it come on because it is pretty subtle. MDS is on by default and can only be turned off with a modded PCM and tuner to my knowledge.

Like said above. It's on and working but it's hard to tell when it goes into mds. There is a thing on the screen that will show "eco" but I don't think that necessarily means you are in mds

My 15 Sport did the same thing. There's a setting to turn the light off and on in your setup screen. It was on my touch screen setup on the radio if I remember correctly.

I too have 2016 Sport 4x4, as far as I can tell the MDS is always ON. I can hear mine when it kicks in though. Of course, I now have a Borla muffler which makes it more apparent but not intrusive.

I just got back from about a 30 miles round trip and I averaged 18 mpg with some light city driving. I could hear the deep hum of the MDS while cruising.

Eco mode and mds aren't the same thing.

^THIS!!

To disable the MDS on a '16, all you do is use your gear -/+ on the steering wheel.
Start to drive, press the - gear button once, then press the + button till it shows you're in 8th gear on the instrument cluster, leave it in 8th gear and the MDS will be temporarily disabled. (I say temporarily because you need to do this every time you take the key out and restart the vehicle. Better than getting a new PCM as it won't void your warranty. It's a pain to do all the time, but I got used to the MDS as it saves my gas. Not like I bought the Ram Sport 4X4 regular cab 5.7 to save gas. LOL :crazy: I do shut the MDs at least once or twice a week.)

Ok, I'll check the menus and see what's there. I didn't do anything on the old truck, but a little green light saying MDS would come on over in the lower left corner of the dash. Don't see that now.

There isn't a MDS light, there is only an ECO light that shows you're driving "economically". MDS is usually only detectable by a change in exhaust note.

Yeah,.....I don't think that the MDS or ECO mode icon shows up on the dash on the 2016 Sport trucks does it??? I haven't seen it on mine.
Maybe I have it set to off by default??

Going to be under the "Fuel Saver Display" section with a on/off selection.

For whatever reason in RAM's wisdom, they put a "ECO" light on the dash but never mention it by that name in the owners manual. You have to search under "Fuel Saver" for functionality of the ECO light.
