Good call looking in the roof area, mines frozen so I hadn't thought of that. I was hoping to find something in the service manual but I had just thought of it and haven't gotten home yet.
I did call Nissan though and talked to a lady who put me on hold for awhilethen came back and confidently told me "Absolutly, they are a functioning safety device" but when I asked her to send me the documentation showing that she said her supervisor told her
But I think I should be able to gather plenty of evidence though now if I need it
