2024 GLE 450 here. Wondering what people thoughts are on route-based adaptation distronic because I was going my usual route with distronic enabled as usual. Except this time it showed some of these on the dashboard and slowed the car down significantly on the interstate.
Images stolen from Mercedes Benz's video on Active Distance Assist DISTRONIC – Route based speed adjustment. I of course did not take out a phone while driving just to take a picture on my instrument cluster.
Does route based speed adaptation feature use the current navigation in memory? I think I missed an exit intentionally, but maybe it thought I was taking the exit so it was slowing me down automatically. Is that true?
It uses the topography and road information from the map data. The owner's manual lists pretty much all situations it slows down for. Good idea to read that and familiarize yourself with all the features. If you have active navigation then it knows where you are going, so yes as you approach an exit you are supposed to take according to the current route it will start slowing down. It will also do that if you use your indicators as you approach an exit or turn. Basically it uses the map data and hints from you such as the indicators to determine when to slow down.
YOU WILL BE DRIVING THE SPEED LIMIT, PERIOD! (According to your most recent map update.)
And you will be slowing to exactly the posted yellow corner warning speed, slowing probably a tenth of a mile sooner than you would have, at probably 15-20 mph slower than an average driver would take it.
I love the way it automatically adjusts to the speed limit, up or down. No more speed traps for me. My only issue is that ocassionaly, it will suddenly think the posted speed limit is 80 MPH and suddenly takes off. Certainly one way to get a thrilling drive.
The route based speed adaptation is not usable for me. I had it on my 2020 GLC300 Coupe and tried it out, it was just too cautious. I joked that I could, however, get home while drunk with it turned on (that's a joke, remember)
The speed sign recognition cruise control is great. My only issue is that every so often, a bad street segment on the maps throws it for a loop. IE cruising along on the interstate at 70 and some errant tiny segment of the map data says the speed limit is 35 and you slow drastically, or, as TonyF61 said, you take off like a rocket.

I absolutely hate it.
It's not just based on maps, also sign recognition.
It will also miss a good 25% of signs. And pick up signs that aren't even remotely relevant. Mine picked up an 80 km/h sticker on the back of a truck the first day I had it, feature permanently disabled after that.
Oh, and if I'd let it do its thing, I'd get a *lot* of speeding tickets here in Flanders. The unmarked speed limit outside of the highway in Flanders is 70 km/h, in Wallonia it is 90 km/h. Apparently Mercedes engineers didn't think about their neighbouring country and just set it to 90 km/h for the whole of Belgium
I turned this off as well. What killed the usefulness for me was the nav system's insistence on selecting poor routing, and it would kill speed to make the turn when in reality, I'd want to keep going to a later exit (for example). I've left all the other safety systems on.
I turned it off. Going down the PA Turnpike at 70 mph in traffic, the car "sees" a yellow exit ramp speed sign two lanes to the right or speed sign for a curve and the car suddenly drops 15 mph without warning! No brake lights for the poor guys behind me either. Very poorly implemented system.

I have it off. First time I used it going through a toll lane where there was no booth just open lane it tried to slow me a lot in the lane and I almost got hit from behind..
The speed limit adoption/recognition is so far to the cautious side that it is more dangerous than helpful, right up until it mistakes a highway 80 sign for an 80mph sign.

Those are different from route based navigation.
We've got two terms mixed up here and I'm not sure which posts refer to which one.
I have liked using the feature on interstate trips, setting speed at 72-78 depending on conditions, and having the speed adjusted when I come upon a construction zone or downtown area. Speed then only goes back up to speed limit and I adjust upward. However a few weeks ago I was traveling in Georgia. They have frequent signs that say Minimum Speed 40 mph, so naturally the speed was adjusted to 40. After the first few of these I started watching and when I would see a minimum speed sign, I would accelerate, which would suspend the function and ignore the 40 sign.
If it's just shedding speed by coasting then there wouldn't be brake lights, but if it activates the brakes to slow down then the brake lights will come on.
Are you sure no brake lights? If so, very dangerous!
I obviously can't see the brake lights from the drivers seat, but based on how quickly the guy behind me closed the distance between us and the pissd off WTF looks i got, I am fairly confident there was no warning I was abruptly dropping speed. This happened a dozen times before i realized what was happening and figured out how to turn it off.

The WTF was probably about your car slowing down in the first place. I'm sure the brake lights came on and the guy behind you was like why the f**k is this guy on the brakes.
Brake lights absolutely come on when brakes are applied. This is easily verifiable at night, by watching the reflection of lights on cars and signs behind you. Wouldn't be legal otherwise.

100% a WTF gaze. I would do the same gaze but I'd have sympathy for Mercedes drivers since I'm in the know. 😉
I've a S560, and when I see ahead a curving road with those yellow arrow signs showing you are about to enter a severe curving section of road, I immediatley switch form drive mode I to S(sport) and then the car does not do it's slow down in the curving section, then reapply the I (individual) mode from S (Sport Mode). That might help you out or not. On a S560 it's a switch on the center console that stands proud and easy to switch from ECO, COMORT, SPORT or Individual Mode. Pretty sure the GLE are similar (0wn one by the way).
