Multicontour seats - do they work? Or not? Or 2016 fail?
The manual doesn't cover the seat controls at all, and the car's electronic manual refers to a version of the seats that are controlled from the Command/NTG screen. Don't have that actual feature in the car. It's a 2016 with the updated NTG and it almost feels like they were prepared for the next gen seats, but forgot it was the last year of production and hence the actual seats in the car are not controllable from NTG....
To be specific it's the two bottom buttons (circled below) where the top one is supposed to move the lumbar support up and down and the lower is supposed to inflate/deflate it. Or rather, that's what I think from looking at the controls. Maybe that's wrong? Could also be the inverse?
For me, they basically do the exact same thing, just inflates the support, there is no up/down movement.
When you run the massage function, you can clearly feel the support(s) move much higher up on in the back. There are no error codes in the car for seats or seat controls.

Not sure what you mean with safety issue ands message on screen? In the (onboard) manual it states you should use the NTG/Command to adjust the lumbar support, but that menu option is not in my car.
I have scanned the car - that's what I meant with "There are no error codes in the car for seats or seat controls", the car is code free.
For anyone else with a 2016 car - when you use those two buttons - can you feel the support get bigger and smaller as well as move up and down?




With the meecedes specific scantool (sds), if there is a fault with the lumbar support it will show up there. With that tool you can make the lumbar actuate to troubleshoot if the seat or switch may be faulty.
With a higher end scantool like a snap on Solus/zeus/triton/etc or a matco maximus, you'll be able to see a fault if there is one but as of the last update had limited actuation control. I can't remember if seat actuation was supported, and can't speak to the latest software update if that was added.
Btw, here is the seat controls on the 2014. They're exactly the same. Yes, yes the lower lumbar does do as you describe.
Hope that's clearer.

I then scanned it using Carsoft and did not see anything. Not sure if I can actually actuate the lumbar support using Carsfot - will check.,
Just curious - in the '14 car - what does your manual say related to using the seats? Does it tell you to find menu in the NTG?

Is your car a '16 with the updated NTG or not?
WANTED!! - just to be 100% clear - your seat does work - the two buttons perform different functions (one inflate, one move the hump up and down)?

I can’t remember exactly how mine works. (Sorry I’m not home for a while to check it) But I remember there was one time I tried to adjust the lumber, I tried both buttons and what they do is just inflate the part contacting my lower back while I wanted to inflate the upper part. So at least the button that moves it up and down doesn’t work as expected. Then I tried to deflate and it didn’t work. So that means the other button doesn’t work as expected either. Massage works though. Since then I haven’t messed with it and just left it as is.

Easy to see what you have
Sounds like yours doesn't work either then. Or at least not like I would have expected it to work...
Thank you for checking!




the top button inflates the bolster under the knees,
the side bolster switch is used for when not in dynamic. If fully inflated they don’t inflate more in dynamic. So back off the fit if you’re skinny.
dynamic mode is most noticeable when side boosters are not fully inflated prior to selection. The side bolster button will seemingly not wirk when dynamic is selected, and that’s on purpose. Turn off dynamic to adjust.
pulse mode is also the massage, inflating from bottom to top and repeating. It doesn’t do all bolsters.
the lever for lumbar, up is to inflate and down is to deflate (deflate deflates the lower lumbar button function as well)
basically as long as the bags, the modules, fuses etc are good, the logic is such that some buttons overlap and others do not.
my peeve is they removed it from passenger seating:/
I think based on the feedback in this thread - that they work as intended. The intention is just rather "lacking."....




So at least our cars are not broken - just a weird axx design.....
Yeah - and get out there and drive a bit! I say road trip!!
This car is too good to sit still.

I thought it was just me, trying to figure out those buttons. Also did not find in the manual. I hold them and hold them and concentrate on what's changing - I dunno either.
LOL.
