So I drove hers today again. I attempted at every stop. Confirmed same behavior. I can not think it’s this complicated from what been said here. Maybe ours has issues. In any case, I doubt she (or female drivers) would want to use this feature. Any of yours does?

mb2be

why so? Hold or not, you let go the brake and step on the gas. No?

Not sure how many people (male or female) use it on a regular basis or trigger it inadvertently w/o even noticing. There was somebody here not too long ago who had the opposite problem of you. He triggered it every time he came to a stop w/o wanting to, and there was somebody else who had the same issue as you. They just couldn't figure it out. The vast majority seems to have no issues with it, or is not using it. Best you have somebody who knows how it's supposed to work make sure it's working correctly on your car and then show you how to use it. You are likely stabbing it too early before you have really come to a full stop. Just try waiting 1-2 seconds next time, before you give it a stab.

I like MB’s HOLD function best among MB, Porsche and BMW. Porsche’s is identical to MB’s to apply HOLD, but can only be deactivated by driving off, unlike MB’s feature which allows deactivation by a second brake pedal stab. After several years I have come to not like BMW’a AUTO H feature because it engages at intersections, and when parking, which I don’t care for.

It shouldn't be complicated to use, it should be very intuitive. Mine worked to first time I tried it (a quick brake pulse after coming to a stop), and I can get it to work 100% when I want it to on the first try. It really is starting to sound like yours is not working correctly, recommend you have Mercedes check it out.

It takes a while to figure out how much pressure to apply but once you get it you can do it every time.

They really did auto-hold and engine stop backwards tho. I'd rather have control of whether the engine stops and let the brake be automatic. This is how it is in my other cars.

HOLD is applied with a stab, not a gentle press, of the brake pedal. The system actuates based on brake fluid pressure rise time. Speed of pedal apply matters. Pedal distance and pedal force are not the triggers. Pedal speed (pressure rise time) is the trigger.

This can be confirmed by a very slow press of the brake pedal, until you can't press it farther. If you have done this slowly enough, HOLD will not engage, indicating the travel and force alone do not actuate HOLD.

Pressing twice has become instinctive for me. I've never experienced any difficulties with it. Interestingly, I wasn't even aware that my car had this feature for quite some time until I stumbled upon it on this forum. However, now that I'm familiar with it, it has become an indispensable part of my driving experience.

on my GLE580 I don't need to double press the brake pedal at all. Once I come to a complete stop if I press it a bit further (it will feel firmer) the hold will activate 100% of the time. This is the way I was told to activate it as well when I was taking delivery from the delivery specialist at my dealer.

"To use the HOLD Function, simply depress the brake pedal as normal until you come to a stop. If you wish to activate the feature, depress the pedal even further until you see the word HOLD appear in the instrument cluster. Once you see that word pop up, you can safely remove your foot from the brake while the car keeps the brakes engaged and the brake lights illuminated. When you’re ready to start moving again, all you have to do is depress the accelerator pedal or press the brake pedal again and the feature will be turned off. It is important to note however, that the Brake hold function does not work as a parking brake. If you need to park the vehicle, you should shift the vehicle into park and utilize the parking brake."

Same here…no magic involved on my last two cars. Any additional pressure after coming to a stop-fast/slow/easy/harder-activates Hold. Maybe it’s more sensitive on some vehicles

I'm more inclined to believe its operator error or owners being misinformed on their delivery day since it's an easy feature to use. There are a lot of videos out there on YouTube and other social media sites many featuring salespeople from individual dealerships demonstrating it with a brake release brake style of activation which is completely incorrect. There is no reason to double pump the pedal; its simple brake to a stop than push a little further and you will see hold light up on the cluster

Thanks for all the expert help folks.
