Disable auto speed in cruise

Has anyone disabled the feature that automatically changes to the speed limit when on cruise control and the speed limit changes? Is it even possible? That is such an annoying feature?

yes I think manual covers it - an option in settings on touch screen

I attempted to change this and it seemed to work for about a week, but then it started automatically changing the speed back down to the speed limit even though I thought I had turned the feature off.

Can you show us a picture of your settings page? Maybe you're missing something.

These are the settings I had them at. I was confused when I first looked at them but I switched them just now. What is Route Based Speed Adaption? I feel like they both do the same thing?

Yes! It is annoying and dangerous, and I disabled it. On my 23 GLE, it's in the assistance menu under "Traffic Sign Assist" then drill down to adaptation.

Route-based speed adaptation is another entirely different thing which I don't think relies on cameras.
It relies on its knowledge of the road, based on the most recent map update.

Which means that it anticipates the next corner and the next speed limit and the next corner speed warning sign, according to the navigation route you have set and your GIS position.

In practice this means driving at the speed limit, slowing a quarter mile before the lower speed limit ahead, slowing to the posted warning speed for the next corner, which is 10 or 20 mi an hour below where people normally drive.
It's infuriating.
Try it, you'll hate it!

I shut this off immediately as others have shown. I too thought it was re-enabling itself after about a week or two but I realized it was learning my normal commute and would slow down when it expected me to take a turn. It also proactively slows down when it think it should…for example while cruise is set to say 75 and you take a highway off ramp it can slow down to when it detects you are going to enter a sharp circle turn

There are two systems that, in my opinion are equally infuriating, and I turn them both off in the menu.

One is route base speed, and the other is speed sign recognition (or similar wording).

I still don't fully understand what route-based speed does, because I still slow in corners, even though I don't have a destination set - thus no "route."

I'd be curious if you have them both turned off (as I do), because I don't think your experience should be happening.

Route-based speed adaptation automatically slows down in curves, and as you approach intersections or roundabouts as well as highway exits if you activate the turn signal ahead of the exit. These work even w/o an active route. If there is an active route, then it automatically slows down for turns and exits that it knows you are going to take based on the navigation route. So instead of having to signal that you are going to exit the highway, it already knows it based on your route and starts slowing down for the exit. It also automatically slows down for other things such as toll plazas etc. They are all listed in the owners manual and the function is pretty well explained there.

The route-based speed adaptation and speed limit adoption are separate features and options as shown above and can be turn on/off independently. I have the automatic speed limit adoption turned off, but I left the route-based speed adaptation turned on. A nice feature is that you can always manually adopt the current speed limit by pressing RESUME while DISTRONIC is engaged. I use that to set the initial speed for DISTRONIC based on the current speed limit and then manually adjust up for the usual 10-20 mph over. I never actually use the SET function to take the current speed as the DISTRONIC speed.

Thanks for your clarifications.
My experience is similar in some ways, but definitely not when Route Based Speed is disabled but Distronic enabled.

In my case, the car slows in corners whether I like it or not. If I'm following a line of cars on a curvy Road, the line leaves me behind as we go around corners.
It's more than scrubbing off speed, because I see my regen green line in the instrument cluster indicating Active Regen (retarding, slowing). With the cruise set at 60, it might slow to 56. I become a moving obstacle.
These observations are my for my 21 GLE 53.

Separately, ​​​I absolutely detest route-based speed navigation.
Wherever possible I drive two-lane blacktops. Most often, the speed limit is 60, with occasional slow corners marked 35 mph. Normally I would probably slow from @75 and take those corners at 60 or 55 mph. However, the car slows me to 35 mph about 1-2/10th of a mile before the turn. If there's anyone behind me, they charge right up on me because there's no reason to slow that much, so soon.
I hate it.

Also I'll add that the "adopt the current speed limit by pressing RESUME requires a double press on Resume. I'll do that when the radar detector goes off. Maybe.

Hello;

Does anyone regret getting the Drivers Assistance Package? Seems most people disable a lot of the included features?

Best wishes!

Not regretting it at all. I do have Lane Keep Assist and the Speed limit adoption turned off, but I use everything else. If DISTRONIC slows down too much around a curve, then I simply override it with the throttle. There's a bunch of things the DAS package does that are not necessarily obvious. It makes all the safety systems work better, because of adding stereo cameras in the windshield instead of a single camera. At the end of the day as the name says they are assistance systems. I use them when I see fit, but I mostly drive myself, so the complaints I read here aren't really things that affect me. Things like DISTRONIC and Active Steering Assist work well in stop and go traffic and out on the open highway when I'm just cruising and eating up miles. In my daily driving I don't really use these features as I generally don't drive on most days or drive when it's not busy, so I'll do the driving. Since I own an AMG, it's about driving it and not being driven. The assistance systems are great when the driving gets mundane or frustrating.

I've been thinking about starting a thread on this topic, but I need to collect some screenshots.

So to clarify a bit,
The car has way too much power to slow down going around corners with Distronic, so you shouldn't have to override it by adding throttle IMO.

In my case, the car is actively slowing by regenerative braking, in the middle of a corner while the traffic ahead is accelerating. Same if there's no traffic at all.

The Distronic can hold speed on any hill I've used it on, but not corners.

It seems silly to use the throttle to maintain a speed that you have set.

@superswiss do you have any insight about what could be going on? Is it some g sensor that doesn't like lateral g's?

To me it seems like "route-based speed adaptation" is still active in some minor way, even though I have it switched off, with no route.

Any ideas what I might try?

Yeah that sounds like a different issue. DISTRONIC slows down in curves for me, because I have the route-based speed adaptation still turned on. It indicates in the instrument cluster when it does it. The symbol looks like a speedometer with an arrow indicating that it is reducing speed and once the road is straight again it accelerates back up to the set speed. If I turn off route-based speed adaptation, then it doesn't do that. Since I generally set my speed 10-20 mph above the speed limit I like that it slows down relative to the set speed. So, if I'm doing 75mph in a 65 mph it goes down to 65 around the curve and then back up to 75. I just use the throttle to override it, if I want to keep it at 75 even around the curve.

So it does sound like route-based speed adaption isn't actually off in your case. The other thing I can think of is that the SUVs have rollover protection, so it might slow down regardless. I know that ESP is never really off in the SUVs, because of the rollover protection for example. I don't have these issues with my C63 coupe. There's not danger of rolling over, so no nannies that are trying to prevent it.

Number 5 below is the symbol I'm talking about that indicates the reduced speed.

Interesting line of thought. I'll think about it.

I doubt that it's rollover protection though, because it happens when traffic is flowing at 55 in a 65 speed limit. (In that case, I'll set the cruise at 75 with an appropriate following distance.)
Probably less than 0.1g, but you never know about Nannies.
