What is the bottom right button?


From Motor Trend review: http://www.motortrend.com/news/2017-...-drive-review/

 

Could be wrong but guessing the button that extends the retractable arm for the seat belt, so that you can grab it easier when buckling up?

 

RHRAUS is right. It lets you manually activate the seat-belt feeder arm in case you miss it the first time

 

It's the same as the S Class coupe I recently checked out - neat feature


I wonder if this is also in the E Coupes...

 

It is. My sister has them in her E cabriolet

 

Great to hear - thought so too as the E Coupes are B pillar-less and the belt buckle hangs further back like most convertibles


Pity it wasn't incorporated on the C204 C Coupes, I think it's such a cool feature and helps a lot in that you don't have to turn your body and reach back so much.
