That's correct. It has been my experience too. You have to be near the driver side of car and use the unlock button pressed continuously to open all windows and sunroof. To close all of them just press the close button the same way or if you have keyless go press the recessed area on any door handle for some time. It's a cool feature I use a lot of time (on hot days or if parked in the sun).

Yes, my W212 works when you are at a dead stop, then pump the breaks twice without letting the break completely off and when you see the hold signal like this, your Engadget in the hold feature. It's awesome. Thanks for sharing guys.

Dude, you really need to break for coffee (per your dash information)..

Lol, but am really stoked about the hold function.

In my 2010 E550 as in my previous 2011 E350 it only takes one quick press on the brake pedal after full stop to activate the HOLD. The second step on the pedal de-activates it.

My doesn't de-activate it on the second press. To me, it seems to be worthless if you need to press on the brake to de-activate it when you can just press the gas to go when your on the go. Am I wrong to think so?

In my car it de-activates from the second step on the pedal regardless if makes sense or not. But it also de-activates when I hit the gas pedal.

Once I engage HOLD nothing I have done to the brake pedal (so far) will disengage it.

Well, all I can say is what my car does.


My hold also functions very easily. It does not take much force on the pedal at all to engage it. It has gotten a lot easier to engage over the couple of years I have owned the car. I also use it a lot. Almost every time I have to stop at the lights. Makes so easy to take off with a touch on the gas pedal.


If your engagement takes a big force you may need much bigger force to disengage the HOLD. In my cat it takes more force to disengage than to engage but the force is not big at all as it takes very little to engage it.

You disengage the Hold function by depressing the accelerator.Unless I'm mistaken that's the only way it can be done.You only need to depress it slightly.

Please don't get me wrong nor am trying to being sarcastic, but if I am at a stop sign or stop light. I would not want try to disengage the hold function when the light turns green and I am playing with my brake and the car behind me thinks I fell asleep behind the wheel or worst yet, a cop behind me thinks I'm drunk or something.

I guess this a matter of preference I guess. My preference is to active the hold function and once those lights turn green, my foot is hitting the gas to go instead of the brake and then gas.

If you somehow understood that I disengage the HOLD by pressing on the brake then you misunderstood it. I never use the brake for it. That would just be silly as it clearly is meant to be done using the gas pedal.


I brought the whole issue up when I saw the post stating that the hold activates with a double press on the brake pedal. Mine activates with a single press and cancels with the second one.

After coming to a complete stop mine activates with a single, somewhat strong additional push on the pedal. HOLD does of course disengage with just the slightest press on the gas pedal and is very smooth.

But I can't get HOLD to disengage using the brake pedal. I would find that to be useful when sitting in stop and go traffic. For instance, you've come to a stop behind another car(s) and engage HOLD. Then the car(s) in front decides to creep forward a bit to closer up the gaps - perhaps a cars length worth, and you want to do the same - in much the same way you'd creep forward by releasing a little brake pressure without touching the gas.

Probably picking nits though.

Something odd here. HOLD should really need a double press for activation and a single press for release. One may learn to activate it as if it was (almost) a single press.

Just need more practise if it does not release from the pedal (I cannot believe the car would be broken in a way that HOLD would not release from the pedal.

Brake HOLD is clearly a feature that drivers use differently, each one to their liking which is good.

There is another scenario where you would like to be able to disable the HOLD without using the gas pedal for it. Say you are in bumper-to-bumper traffic and the car in front of you stalls. You could be so close to it that it would not make sense to use gas pedal for getting the HOLD to release. It would be much better if it was possible to just de-activate the HOLD the same way it is enabled, i.e. giving a quick press on the brake pedal and with this still having the car not move at all as the brake pedal would be under pressure at all times.


And just think about this on road with severe incline in snowy conditions...

Well, I didn't count the initial press when coming to a stop. To clarify, I press the pedal to stop the car then, after the car is stopped and with my foot still pushing the pedal from having just stopped the car, I give the pedal an extra push - thus engaging HOLD, and remove my foot from the pedal.

I've got that part down.

Lightly tapping the brake pedal (as you would to disengage cruise control) does not disengage HOLD. A firm push doesn't either. Lightly tapping followed by a firm push, nor any other combination I've tried, cancels HOLD.

Maybe lowering the drivers window, while simultaneously pressing the window lock button and turning on the right front map light, then getting out and running around the car 3 times - counter clockwise, close to the parking sensors will do it.

I'll try that this evening.

Hey, I'm sorry if I misunderstood you. All I can say is that the forum was the one that I have learn allot about my car that I bet most MB sales doesn't even know. I am very grateful to learn of the hold function as it really helps on city streets where you will hit a red light every 5 minutes so it seems. I like how much my W212 hold function works which is I tape on the brake twice after coming to a complete stop to activate the hold function and hit the gas to disengage the hold and go.

I have nothing, but great reviews for my car which I got CPO 5 months ago all thanks to members on this forum. Since my W212 purchase, I have had both of my Bi-Xenon headlamps, interior wood panel 2x$199 full dealer detail ( 1 detail used already and another detail I plan on using next month ) all free of charge. I feel awesome to have made the switch to my W212 thanks to my dealer and this forum.

I tested today your theory of a double press. And yes it works. The first press of brake engages the hold and the second press disengages hold (the engine starts and car moves forward), this alternating theme continues as I continue to jerk the brake pedal... the brake and the hold function turns on and off alternatively.
Not sure this is of any practical use though. I just wanted to test .

I wonder, then, if it is a difference between cars that have ECO and those that don't.

My MY11 E550 does not have ECO.

Dan

My 2010 E550 does not have ECO either.

Just to be clear, Arrie, yours does not disengage HOLD by pressing on the brake pedal either?

My 2011 works with a simple press on the brake pedal after I stop and all I need to do is push the accelerator to go.

Yes it does. I have done it and was amazed myself that the HOLD actually released.


Does your HOLD also work on reverse gear? Mine does.

I love this feature and use it frequently.

So strange that yours does and mine does not. I tried again last evening and no dice. Once I engage HOLD the computer steadfastly refuses to release the brakes regardless of what I do to the brake pedal.

I don't know about reverse. I do know it doesn't release HOLD when I cycle the transmission between N and D. Tried that a couple of times.
