Urgent help symbol of my Peugeot

Hello a while ago when I returned home, a light witness has been lit in the picture of my peugto 406. I don't know very well to explain it for it, a website that explained the symbols or something AI would be of great help. It is orange located at the top of the right of the box next to the speed box. It is orange is like the buckle of a belt (of a person M refer to its shape) is like a buckle on the one hand is dotted and on the other hand it is smooth. It is not a fixed light, flashes, thanks

It is not the one that indicates the safety synturon?, in any case in the owner's manual all the symbols appear, I think it is here on the page, in the workshop also but it is a lot of information.

I forget if the light is yellow and does not have so much you have so much to worry, the light of the airback is working?
