Screws (Fig 1) on extending support	unscrew.
Tilting/sliding roof switch	press to " roof up ", allow control cable to run out of gear unit and pull out toward front. NOTE: If the control cable cannot be moved with the electric drive, use the emergency actuation (Owner's Manual). If the control cable cannot be pulled out, disassemble the gear unit of the electric drive (77-180).
	If the control cable still cannot be removed after disassembling the gear unit, it is stuck in the tube, which must then also be removed (77-150). It should be possible to pull out the control cable with a maximum force of 70 N. Perform this test with a spring balance (Fig 1, commercially available tool).

When installing the control cable ensure that the guide (Fig 1) slides into the slot in the tube.
