Deactivate distronic plus while using cruise control.
Is it possible to Deactivate dostronic plus while using cruise control. I find it annoying when on interstate and just don’t use cruise control.

HOw is it annoying as cruise control?
Does the same thing.... just slows if car gets too close in front which you have to do with old school cruise....

What happens if you just turn off the two distronic buttons on the dashboard to left of the steering wheel? I have one button that has a steering wheel logo that I assume turns on the auto steering feature, and one button with a picture of a car in between lanes, which I suspects alerts if I cross a line.
I haven’ played with it enough to know what happens if you turn just one on.

By activating the Cruise control, you automatic activate Distronic as well. If the Radar don't see anything in front of the car, the system acts as a normal Cruise control. As soon as the radar detects a other vehicle it shift to Distronic mode, and keep the Chosen distance. If the vehicle disappear it goes back into Cruise control mode.

If distronic comes on automatically with cruise control, then does that mean I don’t need to worry about having these two buttons pushed when I am in cruise control? I have had my car for 2 months, so I am leaning about these features myself.
Thanks in advance.

The systems interact and depending on what combination you chose, you will getting the according benefit.

You are cruising just over speed limit on interstate quality road. In about 30 seconds your car will change lanes to pass a semi-truck. In about 25 seconds a car already in the left lane will pass you and start to pass the semi.
Under scenarios like this, as the trailing car passes you, you SHOULD be able to change lanes into his wake. But if you do this, the DP feature slams on the brakes (which is completely unnecessary.)
Now imagine a third car 10 seconds behind the trailing car you are trying to blend in between the two car and all 3 cars pass the semi.
In this case, when DP slams on the brakes the 3rd (innocent) car is put in a difficult situation.
I, too, leave it off 90%+ of the time.

Interesting...
I have different MB but it only slams on brakes when speed difference is very large like 15-20mph.
But if I am going 75 and Semi in your example is going 70 my car slows gradually as if I let off gas to coast up behind.
Then I stay there at fixed distance until those following cars pass and hit my blinker and change lanes and speed up again.
Now if I was going 85mph and came up on same semi doing 70mph - then yup car hits brakes and does not coast.
I think issue is car does everything from same distance point no matter speed distance....
where humans we can react based on this difference..
Maybe MB has new Distronic program??
I hear 2019 and later versions are light years better then older gen cars.
Thanks for info always like to learn.

I totally agree with your comments above. I have had too many occasions where the vehicle unnecessarily hard brakes due to the distronic & cruise control. I only use the cruise went on the interstate in very light traffic I just got tired of the unnecessary hard breaking, plus it will prematurely wears out my brakes.
Cruise control is worthless unless there is no traffic.

OK, an example::
a) you look out the rear view mirror and see a car heading your way followed by a second car 10 seconds further back at same speed,
b) you observe that the car will pass you in 20 seconds,
c) you will reach a semi-truck in front of you in 25 seconds,
Any driver can manage this situation:: allow car to pass and pull out right behind him.
The way distronic handles this situation is to see the semi-truck in front of you just as other car passes and slows so you have lost you speed and if you pull out between cars you will endanger the second approaching car due to loss in speed.
Alternately, distronic does not start to slow as the truck is far enough away, but as you pull out behind first car dstronic slams on the brakes and endangers the second following car.
I turner Distronic off because of these situations. It is very annoying.

DISTRONIC, and cruise control in general for that matter, active steering assist and lane keep assist are as is in their name assistance systems that are designed to take over some of the driving functions while the driver continues to stay alert and in charge. They do not replace the driver and should really not be used when making maneuvers such as the above example. Use your judgment.

A bit of an older thread, but playing devil's advocate here. This is a fairly unique situation where it's probably best to take manual control of the car. First off, you can always override DISTRONIC using the throttle. The moment you step on the throttle, DISTRONIC suspends its operation until you let off the throttle again and then it resumes. But perhaps in a situation like this, it's best to hit cancel and take full manual control. Alternatively, DISTRONIC in conjunction with the active steering assist can change lanes automatically for passing when it's safe. All you have to do is turn on the blinker, and then the car will accelerate and complete the lane change for you. It may not do it in a situation like this, though, if there is not enough room to do it safely. Just imagine one of the cars you mention here abruptly steps on the brakes for some reason. I would argue this is a situation where the driver should be in full control, even with regular CC.

good post superswiss...
As always these things are not mean to take control of the car like HAL the computer... but supplement and assist a driver to sort of EASE the work load.
Also if you think car slows too lat for truck in front then adjust distance by turning end of stalk to adjust distance car should run behind car in front.

Anyone ever get brake checked whilst using distronic? Just wonder if it would break in time.

You can't adjust it close enough.
During my morning drive most are doing 80-90mph on 4 lanes, lane changing with maybe 1-2 car lengths gap (at best).
Distronic is literally worthless unless I want to get passed and cut off by the entire world.
It would consist of- I have 6 car lengths in front of me doing 85. Everyone sees this and closes that gap, car brakes and makes another 6 car gap, gets filled over and over.
With regular cruise someone could fill the gap and I cruise along with a few car lengths ahead of me and no constant/excessive braking.

I find Distronic so annoying that I don't even use cruise in this car. Besides the above,.. where people assume you're leaving room for the entire world to pull in front of you, and the car is constantly on the brakes...
I also find that I'll be catching a car / truck in the middle lane,.. and before it's time to move left, It's gotten on the brakes. Then when I'm over enough it gets back on the gas. Like a little punishment for not moving over sooner. The Germans never heard of drafting? LOL
Then the last time I drove it there was a truck in the lane to my right,.. and suddenly it decided to brake hard at 75. I veered to the left as much as I could to try to get the radar to not see the truck, and it then let me continue.
The Distronic is rather nice on a limited access highway. But the rest of the time it's just annoying. I have to be on my toes to outsmart the car to keep from getting punished.
Perhaps we can just unplug the radar up front? We'll get a warning for sure,.. but would the cruise still function?
