How to set off the seatbelt beep? (3)

Some time ago I posted about how to set off the seatbelt beep, see this topic. This weekend I had to disconnect the battery for a small change to the electric system of the car. After I had connected the battery again I discovered that the seatbelt beep was ON again. So I had to set it off again. I post this information just to keep you posted about it.

Another thing is, when you set off the seatbelt beep and you drive without your seatbelt on, the beep will not sound but the red indicator on your display will still flash like it does normally.
