Power closing assist for doors and trunk lid
The doors and the trunk lid close automatically if:
•the doors are positioned against the lock,
•the trunk lid is lowered against the lock.
It is not necessary to slam the door or trunk lid closed, a
pneumatic power-assisted mechanism draws doors and
trunk lid closed quietly and automatically once the lid
or door has been latched. When the pneumatic power-
assisted mechanism has stopped, doors and / or trunk
can be reopened.Central locking switch
