It allows you to control the settings of the passenger seat.

Thanks for the reply. Which settings does it let you control?

Yes - heating levels, seat motors, and if you have it fan levels for ventilated seats, As estark posted: everything you can control on the drivers side, once you press this button, all controls switch to passenger seat.

I call it the "annoy the wife" button.

Can you actually record (and recall) a passenger seat position memory preset this way?

Has anybody come up with a clever or unexpected use-case-scenario for this feature (other what it was originally intended for)? (Use with pets, warming take-out food, launching objects, etc.)

I consider it a Stupid Mercedes Trick. I think I found it useful exactly once. My wife was putting a 5-gallon bucket with flowers in it behind the passenger seat and I was putting something behind the driver's seat. I was able to move her seat up and then back again after she positioned the bucket.

That said, the button that my W220 had was much more useful. It was part of the right rear seat control and switched it to operate the front seat. I used that all the time. That way, she could have easily moved the seat up and back herself while inserting the bucket. Why they deleted that feature and added the much less useful form of it at the driver's seat is beyond me.

I use it frequently to adjust the right seat for occasional passengers that do not know how to adjust the seat. In particular my wife is 5'5" and my most frequent other passenger is a 96 year old 6'4" neighbor.

Through coding, that button can be programmed to be the passenger ejector seat.

6’4 at 96? Must have been over 7 feet when younger

Useful for programming memory settings for the passenger seat. Let your passenger fiddle until they're comfy, then go ahead and program their own memory button.
