I'm sure your manual will have the instructions. It's clearly stated in the manual's index.

The only thing in the manual is instructions on disabling it with the button. This does not turn it off as default, it only turns it off while you are driving it that time. I want it off when I START the vehicle.

 

The second paragraph on page 145 of your 2013 manual leads me to believe that if the ECO system is deactivated with the button it will not reactivate the next time you start the vehicle. My brothers GLK is a 2014 and he is not here right now so I can't check it right now.

Funny, I followed the link, and I found that the first paragraph on that particular page clearly states that the system is re-activated every time you start the car. ?

 

I'm with the OP and would like to disable that Eco function for good and never have it on. What a pain while driving in So. Cal every day
I push that button every time I start the car which happens to be dozens of times per day

 

my 13 you have to push the button. I don't think there is a way to do away with it for good.

its a epa/gov thing. no way to get rid of it.

it does suck in stop/go traffic, but in general you will get used to it. I know I have.

When you drive about 50K miles a year and a good portion of that is in stop & go traffic you never get used to it. Not having the choice to turn it on or off is a really poor design in my book

 

According to the manual the ECO function will only operate four times in stop and go traffic then go into standby or (yellow) mode. Does it turn back on some time later??
My brother just bought his GLK and loves the ECO mode. I can't wait until I get the call from him stating that he hates the ECO mode. If I trade my ML for a GLK one of the purchase conditions will be to permanently delete the ECO mode.

There has to be a way to disable it! I remember owning an Audi which had features that were turned off and if you hooked a laptop to the onboard computer, you could turn them on or other things off... things like how the windows operated, the lights, ect...

 

I stopped into the dealer this morning and asked the question to the service manager for the 4th time and he stated NO.

Kept track of how many times this thing started/stopped on Wednesday of this week. I gave up late afternoon when it was over 100 times
Sorry but I will never believe that this is good for the car and won't cause premature wear on the starter/battery,etc..

Maybe it's just a great thing for those that start and stop about 4 times per day but it's not working for how/where I drive.
My plan was to write MB and see what they say. It might get to the point to where i buy another vehicle that does let you disable the "feature"

 

Not only is it annoying, the ECO mode induces additional wear and tear and is a definite safety hazard. It adds additional cycles on the starting and charging system, and also stresses the battery. MB batteries are expensive. I also am concerned about lack of lubrication in all engines at startup, before the oil pressure is up, resulting in more engine wear with frequent starts. I also question how much gas it really saves, since all engines require a bit more gas to start than idle for a short period: lots of stop-and-go driving could result in more gas usage (a minor point however). My biggest concern, though, is the time it takes to spool up when starting. If I am trying to shoot a gap in traffic even a short hesitation could result in getting t-boned.

I have spoken to the local MB service department and the ECO switch can not be permanently disabled, at least not by them. Additionally, disabling it will void the warranty. And somehow it feeds into the emission control system, so a code gets set if it would be permanently disabled, and as a result you won't pass a smog check.

I just push the button and shut it off every time I start the car. A nuisance, but the only option.

 

you just have to push the button every time. NO WAY AROUND IT. If this is such a pain and it can be to some, than buy an older car. Due café standards for 55+ mpg by 2025 ALL makers are doing this. You can think EPA/GOV and the car makers for accepting this feature.


but with these eng being direct injected its not really wasting money to start. now back 10 yrs ago it would waste more fuel than to just let it idle.

the ECO is no worse on the internals of the eng than a cold start after the engs has been off for 10hrs or so. the trans has an external oil pump that keeps the trans fluid circulated while eng is off. the starters are designed differently and don't pull a lot of amps on the restart of the eco mode. REMEMBER the eng is at running temp so started draw is 3/4 of what it would be on a cold engine.

I am not for this, but this is the wave of the future. GET USED TO IT. its here to stay.

 

You can't disable it. But if you use the paddle shifter, it will think that you're in sport mode and it is disabled.

but yes putting it in "S" mode it shouldn't cut off either.

 

While I may disagree somewhat with your technical assessment (just opinion either way until years of data related to repairs, battery R&R, etc, are accumulated), the safety aspect is my big concern. Even with a new car there is slight hesitation upon restart, which results in a slight acceleration lag as engine spools up. I suspect an older car would be eve slower to restart. Longer lag means increased chance of a collision when trying to squeeze thru a small gap in traffic. So I push the button to disable.

Last week I was traveling and my rental (Chevy something-or-other) had this very undesirable engine shutdown-at-idle feature. Unfortunately it had no disable feature, other than manual shifting. I hadn't driven a "manual transmission" in a while, so it was somewhat entertaining.

These types of gimmicks are the wave of the future, thanks to the enviro-nazis and their attempts at nanomanaging the most minute details of the economy and people's lives. Perhaps with the thinking party back running both houses of Congress perhaps we can get some relief on this idiocy.

 

The Chevy Equinox rental I had, had an Eco button as well but not sure if it's any effective since its seemless.

Btw posting at 30k feet on my way to Asia!

Well, Eco-Restart is a European mandate - so get with it - and the MB is specifically executed as the best-in-the-bunch Eco especially for restart - drive a BMW or Audi and you'll feel/hear the disappointing difference... now comparing MB Eco to Chevy Equinox... my apologies, get a grip..

 

I have the autostop in my escalade hybrid and even in traffic it is seemless. GM Eco is seemless, that's why the equinox is a bestseller. I'm glad my Range Rover sport doesn't have one.

No it doesn't stress the battery or starter, it's an amazing system , it doesn't use the starter, and the electricity used to fire one plug is almost nothing. What it does is it senses which plug - cilinder is just at the firing point, It then fires that plug to start the motor. What I dont like is the system allows oil pressure to go back to zero.

 

It sure sounds like the starter is engaged to me...

My wife wanted to purchase a new car so we went over to the MB dealership to check out the SUV's. First question she asked was if it still had the eco button and if you could permanently disable it. They stated no so the discussion ended right there. The salesman did state that most all customers HATE that "feature". We drove right across the street to Lexus and purchased a new Lexus where you CAN keep it off. I don't think we will ever purchased another vehicle where you don't have the option of turning it off. I'm not really too impressed with my GLK anyway so my next car might be purchased at Lexus too.

 

So, can I permanently disable ECO mode via an ODB II scanner. In reviewing this thread, I did not see that question addressed. I have a 2016 e250. I know MB would not endorse this, but with the aftermarket ODB devices out there is this an option?

Also, is there a good thread discussing the pros of having my own ODB II scanner?

 

I personal like the eco funktion and belive it does save gas and the way mine starts up there is barley a difference between engine on or off.
However I see 2 options to turn it off by default.

1st find the wires of the eco off switch. Bridge these with a timed relay controled by ignition. So now you turn on ignition start the car and let's say 1 min later the timer disables eco.

2nd better way, find sombody with SDS Xentry and Vediamo and have them disable eco.
If you around washington dc I can recommend sombody.
Or go all the way and your own Xentry it's a good investment no matter what.
Will cost you around $800.
