Caution! Using any lubricant other than lithium grease "G 052 150 A2" may change the sliding properties of the guide channel and cause vibration. If the guide channel malfunctions, thoroughly clean it with a cleaner "D 009 401 04" (remove all traces of grease), and then degrease. Treat the guide channel again with lithium grease "G 052 150 A2", then open/close the hatch several times.
