That makes sense, is it showing an issue with the rear seatbelts?

Older MB cars did not have occupancy sensors for the rear seats.

So, the car knew if the rear seat belts were buckled or not, but it did not know if any or all of the rear seats were actually occupied or not.

In this situation, there would no point in alerting you to the fact that one or more of the rear seat belts are unbuckled - because the car can't' tell if it should be or shouldn't be buckled.

What the engineers at MB decided to do, is to simply show you a reminder of the situation with the rear seat belts any time you drive off. You can then decide for yourself if you're happy with it (i.e., because there's no one seating in the rear seats), or you want to take some action (e.g. asking the passengers at the rear to buckle-up).
 
Oh no. Its serious if that graphic comes up. Under the legislation which binds car manufactures, German TUV and EU Health & Safety legislation it dictates that your Mercedes Benz vehicle is not permitted to carry passengers who look like those pictured.

So if you see some people who look like squatting pixies at the side of the road, dont be tempted to pick them up.
Its perfectly fine for normal passengers though so long- as you dont try to carry them on the roof bars.

Thanks for the explanation, so there are no sensors in the back seats, the graphic is to remind me to make sure all passengers have their seatbelt on :)

Correct.

It will also show if any of the rear seat belts are bucked-in, but - again - it won't know if there's anyone actually seating in the seats where the seat belt is not buckled-in. Which is why it does not actually issue a warning as such (which is does for the front seat belts) - instead it is just giving the driver the relevant information.

The graphic image will also come-up if a passenger in the rear seat unbuckles their seat belt while the car is in motion, e.g. if they are preparing to leave the car before you have actually stopped. But, again, it's for information only - it won't come up as a warning as such.

I'm sure many of us have yearned to tell the mother-in-law to BELT UP ! 🤬
 
It's one of features that are assessed by Euro NCAP. It doesn't stipulate that occupancy sensors are required, but you must be able to see the state of the buckles, at the start of each trip, without having to turn around. It assumes you know whether or not you have anyone sitting behind you.
