A system may include a door track, a guide mechanism, and a sequencing mechanism. The door track is mounted to a door. The guide mechanism connects the door to a vehicle body. The guide mechanism may include a first member connected to the door track and a second member connected to the first member for rotation relative to the door track. The first member is movable relative to the door track. The second member may engage a body track in the vehicle body and may be movable relative thereto between a first and second ends of the body track. The sequencing mechanism may include a third member locking the first member relative to the door track when the door is between the intermediate and closed positions and a fourth member locking the second member relative to the body track when the door is between the intermediate and fully open positions.
