That's your safety restrainant system. Theres a tutorial on how to reset it using paperclips which I used and it worked fine. But if there is something accually broken then it stays on and youd have to see a mechanic. Ussaully it could turn on when taking out a seat, messing with your stearing wheel or any of your airbags, or sometimes disconnecting the battery. Here's the link to try resetting your srs system.
