Nope, starter

And as you already know where the jam occurs, why not push the off button?, its no more effort than adjusting the AC or changing radio station.

The Infamous C450
Still in the break in period and abiding by the preferred Eco mode for the first 1000 miles, is it also recommended to leave the start/stop on during that time? I usually do but curious?

Or you pull into a parking place, the engine shuts down, you put it in park, the engine starts, and then you turn off the engine.

I get annoyed by the feature in a traffic jam or when parking as well. It's too quick - they should've made it so that it has a 2-3 second delay (or even better, a user configurable delay).

Not that this will make anyone feel better, but there is a setting in the ECU which allows the Stop-Start logic to be turned off by default, or for it to remember the last mode setting. The configuration is locked down, so don't go asking your dealer to change it for you.

If the situation requires quick acceleration, I don't want any additional hesitation on top of the engines turbo lag.
I am starting to think that in many areas, the C-Class is performing very differently from one car to the next. Individual driver sensitivity cannot explain the large differences of opinion on this and several other areas of complaint. However, there is one pattern of complaint common to several areas of dissatisfaction (including this start/stop feature). That pattern is found in the complaints of drivers who really want their car to be an extension of their own nervous system. Over 50 years ago, Road & Track and Car and Driver magazines used exactly this language to describe the pleasures of the best sports cars. In sedans, that connection is now found only in BMWs.

I like the start/stop feature. As I have said in several other places, "spirited" driving is not possible in my area of Massachusetts. I hardly notice when it shuts off. In Comfort mode, the engine is pulling by the time I depress the gas pedal to the desired point and the turbo lag has been overcome. I simply do not feel any difference in desired acceleration. At a couple local intersections with limited visibility, I do use Sport mode. Then there is no turbo lag; the car responds to the gas pedal instantly. Then the start/stop feature does cause a barely noticeable hesitation. But the response is still more than strong enough to take me safely across the intersecting street. As for start and stop traffic, it is obvious that instant acceleration is never required. I am fortunate to have Distronic Plus, so I can just turn start and stop traffic over to that wonderful feature.

That could be a US feature but it is not supposed to start again when selecting park, removing the seatbelt or opening the door on the oither hand will start the car again.

Indeed, it does. In America, we are affected by pragmatism, good, bad or indifferent, and we deem such nuisances irrational and unamerican! . How's that for Chauvanism?

Maybe, just maybe, this is why we American's are not always respected around the world. Just sayin........ How's that for a dose of reality?

I mean really. I don't like the eco start/stop feature either. But it's easy to deal with and it's what prompted me to create my own Individual setting in my car. Get in the car, start it, hit the Agility Select switch up to I and drive off without ever having to deal with Eco. Plus it adjusts all the settings I prefer using in one simple setting.

Pragmatic or just lazy? I guess there's a reason the fattest people in the world are Americans.

But, then there is reality based on statistical fact: we fat pragmatists work more hours than ANY country in Europe, with no or short vacations, at the highest productivity level in the world. Sueeee, pig, pig, pig....

I dunno......seems to me, plenty of European's live in nice homes, eat good food, drive nice cars, have on average 4 - 6 weeks vacation/year, many more holidays off to be with family and friends and have a very nice standard of living. I'm not so sure the fact that most Americans are obese, die of heart disease at an early age, take less than two weeks vacation and often have 8 or fewer holidays/year is cause for bragging. Just sayin.......

There is also a company in Chicago that sells an add-on solution for this, if simply pushing a button on start-up is unacceptable. Do a seach of ECO start/stop on this site and you'll find the name. Enjoy.

Actually a combination of both:
  • The ME knows the position of all the cylinders when the engine is shut off via ECO by way of B70 Crank Position Sensor
  • When restarting the ME uses this info to select the cylinder that has the most favorable position for a controlled combustion
  • By Injecting fuel at the correct time, the very first compression stroke can be utilized to support the starters action
  • Resulting in a very brief operation of the starter motor

The now disproven proposition was we are lazy, hence obese. There is no issue that we work and die like dogs.
