If the hydraulic fluid is low, there is a problem as it's a sealed system. A hose is more likely to have failed. First step is to identify and replace the hose. They are individually numbered as they are different lengths. The numbers can degrade over time.
The hose is held in place at the roof end by a circlip type of fitting. That needs to be retained and used again. The hose should come with a rubber washer and retaining clips for the pump end. You need to remove the cover plate for the pump, which will enable you to change that end of the hose. It might require levering up after undoing the two Allen bolts. It is fiddly to replace the retaining clip. I gradually moved it into place using a tiny screwdriver blade.
Once the hose has been replaced, time to top up the reservoir. You'll notice the filler plug is below the level required, so you need to put the car on a slope and jack up the rear right hand side of the vehicle. The system is self bleeding, so the roof will need to be operated manually, opening and closing several times, topping up the reservoir after each closure.
That's as far as I have got at the moment as mine will not operate yet.
Good luck.

remove the rear boot qtr panel cover to get to the pump, the bowel at the bottom of the pump, is held by a jubilee clip( 7 mil socket required, you cannot make the clamp tight enough whith a screwdriver), undo the jubilee and top up the fluid, wear gloves, carefully raise back bowel to pump, tighten jubilee clamp with socket and rachett( this bowel is under imense pressure).. Job done. If your pump has a pressure release, ie mk 3 astra, release the pressure with this(looks like a t piece on the side of pump) top up, then do back up the pressure release tap, and there is a red handle on the side of the pump, pump this to build back up the pressure inside the pump, it will go stiff, then job done.
