Trunk / Liftgate: Description and Operation



Closing Aid

When closing the rear window, an electric closing aid with an integrated middle attachment and eject mechanism also kicks in. A spring-loaded lock holds the rear window leaving a gap of approx. -> length: 20 mm. If this lock is pressed too far, an electric motor activates the closing aid, which automatically closes the rear window.
