This has happen a couple of times recently. The message would be pull over safety and stop top open. I would pull over and press top closed button and the message would say top is closed To correct this, I would press the open button until windows went down and the trunk started open. I would stop and then push the close button and the top would close, windows shut and message would be "top is fully up and locked". However, this time I pressed the open hood button and the windows started to drop down and the trunk started to lift. I then went to press the closed button, but nothing happen and the reading said see service manual. I followed the instructions in the service manually but noting happened and said it needs to be serviced.
Roof top alarm sounds that the top is open, but it is actually closed. on 2008 Volvo C70
Possible sensor malfunction...
