The R230 actually has seat belts for whatever you put behind the seats to secure your bread, milk, and eggs while you motor about with the top down. Wonder why there are none in the R231.
No worries. I'm sure it's just an English/American thing.
I found all of that stuff in my cubby (the eggs, milk, and bread were a joke). Structurally, I haven't looked yet. It's 8:50 am here, the crack of dawn for us retirees.
The thing about being retired is that I go to bed when I am tired and get up when I’m finished sleeping - I never worry about the clock.
My father in law lived 30 years after he retired and never changed his routine.
Up at the same time every day
Breakfast - same time, same thing every day.
Coffee - same time
Lunch same time
Tea same time
Dinner same time
Bedtime same time
Because some genius would sit a small kid back there.

What year was that? I don't remember my 2004 SL500 looking like that, other than to have the straps. I gotta tell you though, that if something like that suitcase could get sucked out of the car, you'd be approaching the speed of sound.

The post was intended as an example of the type of suit-case. I imagine the straps are to stop the case injuring you. Didn’t some models store the wind deflector there?

I just realized that I don't remember seeing a roll bar on the R231 like we had on the R230. Does the R231 have a roll bar? (Again, I'm too lazy to go look. So much easier to just ask here.)
It has two rams that pop up from the rear, either side of where the factory wind screen sits. Can't find a picture now but there's one out there somewhere!

THe QR code in my passenger door has this information

OMG I was gonna make a post with that question. MB must have given us some protection during a roll over. Surely there must be some hidden pop up roll bar someplace, or something right?

Hood deployment increases the distance between hood and non-compressible engine, creating more energy absorption and less potential for pedestrian injury. Similar idea as a crumple zone.
So could someone just explain in english what happens as far as any "roll bars" should we flip over?

How tall are you? j/k
Apparently from @rorywquin post, there may be two "roll bars" that pop up behind each seat from the black grills on the rear deck. I always wondered what they were there for since they are solid and couldn't be for rear speakers. I'm going to take a closer look.
Also, it seems the mystery of what the batteries do has been solved. The little one is for the start/stop function and the big one is for everything else. My only question is which batter is used to initially start a cold engine?

The little one supports / enables start / stop and the electronics and other systems of the car during start/stop. The big one always does the starting of the engine. The s/s will only operate 3 or 4 times in traffic and then wait until the big battery has charged up a bit.
The little one is 200 CCA (vs 850 in the big one) and 13Ah (vs 95 in the big one). I cannot see the little one surviving many start stop cycles.
I copied this from the site linked below - there is a lot more information to read on the site.
What does a Mercedes auxiliary battery do?
There are 2 types of auxiliary battery for Mercedes-Benz cars. Some cars have mini battery, very similar to primary (main) battery just much more smaller in size and other models auxiliary battery is completely different. This new shape battery aka voltage converter has been fitted to new C class W205 S205 C205 E Class W213 S213 GLC X253 C253 and S W222 class cars.
New shape auxiliary battery is completely different if you compare them to the first generation auxiliary battery and it has second name for it - voltage converter or convertor.
The auxiliary battery runs some or the most of the'cars additional functions or accessories such as PDC sensors, multimedia, various radars, stop start function and so on.

On detecting an impending danger of the vehicle rolling over, the airbag control unit sends a corresponding signal to the roll over protection system. This is quickly extended behind the rear head restraints, helping to maintain a safe passenger compartment. The roll bars are extended not by spring force, but - for the first time on a Mercedes-Benz - by pyrotechnical means, using a gas generator.
Thankfully I was able to replace both of my batteries this morning. So glad I did it first thing, because it’s storming like no other right now. Everything went smooth and easy and was finished both in 30 minutes total.
I replaced both batteries today and want to thank everyone that posted here for the valuable info that was shared. TMD’s 30 minute record for swapping them out remains safe as it took me just under an hour to accomplish the task.
One additional tip I’d like to share is that I took my time on the aux battery because I didn’t want to cut those tabs if I could avoid it. I removed (only 1/2 way) the center console upper trim piece from the rear of the console, adjacent to the battery cage. By pulling that piece out I was able to gain a little more wiggle room to pry the two tabs away from the console and free them. I’ve attached a picture showing the trim piece disengaged.
