What is the minimum safe operating temperature for the hydraulics that power the E93's top? On some cars like the Smart Fortwo convertible it's a fairly high 5 or 6 degrees C, anything colder and it won't even let you move it.

I've heard from my SA friend at Mercedes that they have cars coming in now and then where the owners tried to lower or raise the top in sub-zero temperatures and blew the hydraulic lines.
