Important: The screwed joint,

form of a self-cutting threaded bolt and may only be released or
screwed in again 1x. After being screwed in again, the bolt head
must be marked with a yellow dot. When the special bolt has been
released again, the front seat backrest must be replaced because
the threaded insert is worn. If the special bolt is twisted when
