Had one of these cars in here about 4 years ago...regular customer. Rollbar deployed whilst driving through town.
Was told by MB tech' at MB of OKC that the red 'top' button needs held on for 4 to 5 seconds with ignition on. ( KOEO.) to sync' the system.
No go...sent computer to be checked...no fault found..... all position switches where okay .
Sent vehicle to dealer due to now 'off lease'.
Owner said he returned car to lease desk and they sent it straight to the shop.
I called next day to ask what they found...they said after plugging in 'star tester' the top operated as per factory.
Maybe...you could have Mb do same for you.
