Question about HOLD
We find the HOLD feature very useful....when it works, which is not always. Is that inconsistency to be expected, or is there a method to getting it to happen most all of the time?

info on Activating/Deactivating the HOLD function from mb... link specific to e-class but most likely similar for v167...
might also be mentioned in your manual. Drive safe.

Mine work 99%.
In my 2016 S-class, i have to press super hard or all the way to activate it. In the end i am too lazy to use it.
In this GLE it seems much lighter and easily engage.

I apply medium pressure on the brake and HOLD gets activated 100% of the time. Its one sweeping motion.. brake to stop the vehicle and then some more to activate the HOLD

Mine works 100% if you do the right step like others have mentioned.
Brake until car comes to a complete stop, then press the brake paddle more to activate it. The pressure needed depends on the initial pressure the braking. If you are light on brake before the car stop, it requires less pressure to activate hold. If you are already half way thought the brake paddle when stopped, you will need more pressure to activate it.

HOLD responds to brake fluid pressure (pedal travel) and more importantly brake fluid pressure rise time (pedal velocity).
Deliberate, swift and firm pedal actuation works 100% of the time for me. Slow, lazy, hesitant pedal application never works. You need to train yourself to use the system.
Similar in principle to commanding a transmission downshift. Pedal velocity is far more influential than pedal position. There is no mechanical connection between throttle and transmission like on the 1972 Pontiac Le Mans. Remember the downshift linkage?

I have noticed that it is more or less sensitive on different models if that's the correct way of describing it, but it works 100% of the time when done properly. In my C63 it works 100% of the time, but it takes different additional brake pressure at different times. Sometimes it actually activates even w/o me consciously doing it, other times I have to be affirmative with pushing the brake pedal further to engage it, but it ultimately engages. There was definitely a learning curve, though. I had trouble getting it to engage at the beginning, but now I pretty much use it whenever I come to a stop at a light and it engages every time when I want it. I think the trick is to make sure you first come to a complete stop. I sometimes try to engage it a little too early, but then it's just a matter of pausing for a second and then do it again. I think it's obvious that you only want it to engage if the car has come to a complete stop, and not accidentally during a rolling stop or other braking maneuvers when the car is still rolling, and there is probably a bit of a threshold such that the car has to be at a full stop for at least a fraction of a second. I generally don't engage it right away.

It's easy to convince oneself that pedal travel/position alone is not the way that HOLD is activated. Gradually come to a complete stop, and keep the brake pedal motionless. Then, without lifting the foot off the brake pedal, very slowly push the pedal as far as you can. HOLD will not activate in this situation. Pedal velocity and brake fluid pressure rise velocity is a strong, or primary, factor. Likely in addition to other go/no-go conditions such as transmission in D, vehicle speed = 0, doors closed, engine running, etc.

Classic example of over-engineering. In other cars the brake hold turns on as soon as you stop.
I guess the advantage of the MB system is that you can choose when you want it and you don't have to press a button every time you start the car.

I would disagree that it is over-engineered. I prefer the MB system as it's on demand instead of having to activate it using a button and then it always holds. With the MB system I can decide to activate or not or even easily release it to creep forward a bit and then reactive it all using just the brake pedal.

With BMW it’s either on or off. I would sometimes have to turn it off when I pulled in my garage because when I would pull in if the engine would shut off and the auto hold engaged, it would surge forward with the engine would start again. I prefer the MB system now because I can avoid that situation.

The Audi system works the same and it's interesting that Audi stopped selling it in North America and in Europe it's an extra cost option as far as I know. I can only guess that they got complaints from confused customers in situations like this thinking something is wrong with the brakes. The Audi system also holds the brakes for only a while and then it engages the e-brake instead, because the ABS pumps would start to overheat. Not sure if they figured this one out in the latest models yet, but as said, the feature hasn't been offered in North America since they discontinued it. To simulate the MB style HOLD in my Audi, I used to just manually engage the e-brake while leaving the car in gear. It auto-released like the HOLD function when stepping on the throttle, but the downside was that the brake lights weren't on with the e-brake, so drivers behind me would sometimes think that I'm about to move. A friend of mine once got rear-ended this way.

I don't remember anybody claiming that MB's system is AUTO HOLD. It's on demand as I said above, which is what actually makes it better, IMO.

Correct superswiss it was members claiming they had other manufacturers cars with auto hold, the hill hold assist has been on cars for many years and you have to press the brake pedal to activate it, the difference with the MB system is that once the "hold" is on it stays on until you touch the brake or accelerator pedals, the hill hold system releases after a few seconds. The MB system is brilliant and would be one of the things I would miss if moving away from MB.
