Do the window have to be up before the convertible top comes up on a600sl mercedes?

Yes, on the Mercedes-Benz SL600, the Windows need to be fully closed before the convertible top can be raised. This is a safety feature designed to ensure a proper seal and prevent damage to the roof mechanism. If the Windows are not up, the system typically won’t allow the top to operate. Always refer to the owner's manual for specific instructions related to your vehicle.
