How open hart top manually

I don't know

Check your fuses and top relays to see if they are blown. They should be listed in your owners manual.

My 98 slk230 was already made manual when i bought it. way faster than waiting on the electronics. disconnect all of the body parts from the hydrolic pistons in the trunk. not sure if you need to disconnect a relay or not, but im pretty sure you dont. expose the t30 bolt in front of the mirror on the front inside roof. turn that 1/4 turn clockwise to release roof. roll down windows using center switch, open trunk backwards, release roof and pivot into trunk, close trunk. reverse to put back up.
