Question Question Re. Coupe Rear Seat Headrests

My S550 Coupe Owners' Manual states that the rear seat headrests can be raised and lowered electrically using switch #7 to the right of the instrument cluster.

I seldom use the rear seats but have noticed that pressing that switch did nothing but cause a slight noise in the rear seat area. Since I had my car into the dealer for other work I asked them to fix that.

The service rep called me later and said his tech told him that in the coupes the switch ONLY lowers the head rests. When I asked how the headrests are raised he said only mechanically.

In my '05 CL500 the rear seat headrests automatically raised whenever someone sat in the seat and then the button was used to electrically lower them. I would think that a 10 year newer S Class would at least do that and not require manual operation of the system.

It isn't a big deal but I wonder if other C217 owners could enlighten me as to how their cars work?

Quote from the Owners' Manual:
"Adjusting the rear seat head restraints
Lowering electrically from the front
Turn the SmartKey to position 1 or 2 in the
ignition lock (Y page 151).
Briefly press button :.
The head restraints lower.
Extending from the front electrically
Turn the SmartKey to position 1 or 2 in the
ignition lock (Y page 151).
Briefly press button : again.
The head restraints extend upwards.
Adjusting the rear seat head restraint
height mechanically (Coupe)
To raise: pull the head restraint up to the
desired position.
To lower: press release catch : and push
the head restraint."

I took my 2015 S-class coupe in for its first service after I purchased it last year. I read the same thing in the owner's manual and wondered about it too, so I asked the same question about the rear seat headrests and pointed out that the console button didn't do anything except make a small noise. They afterward reported that the coupe rear headrests are not controlled electronically. My coupe also has the Burmester High-End system with the rear subwoofer, in case that makes a difference.

Mikey, Thanks for the info. I have the standard sound system and my seats apparently operate like yours. It seems strange to me that MBZ would make virtually everything automatic or electrically operated on these coupes but make the headrests manual. It certainly isn't a big deal though since I seldom have anyone in my rear seats.

Just to be clear (unless I'm misunderstanding you). The button on the center dash is to fling the headrests backwards for more visibility to see out the rear window. The rear headrests are in fact manual. Come on guys with your first world problems! Now mind you I haven't pushed the button to fling the headrests back in this car, but that's what it did with my 08 CL 550

But if you think that's odd, why do I have two separate switches to operate the SHADE on my non-opening panoramic roof with no magic sky? Literally both switches do the exact same thing. Open and close the sunroof shade. I was like this sunroof MUST open. Am I missing something?

Lexnoir, I too had a CL500 and was aware of that system. But after reading the S550 Coupe Owners' Manual (quoted in the original post) I had the definite impression that MBZ had taken that system to a new level just as they did in many other systems of that S class coupe. If MBZ had simply written that the headrests had to be raised manually and lowered with the switch, instead of describing how to raise them electrically which it apparently can't do, that would have been much clearer.

I also wondered about having two ways to open and close the roof shade. Maybe that is to make up for us having to raise the headrests manually.
