Mine never stops blinking either. I think it's just a dummy light to trick would be thieves looking into your car into thinking you have an alarm.
Edit: I just read the manual in your link. If you don't have a smart key FOB that light blinking indicates that your vehicle immobilizer is active and functioning. If the light is steady on there is a malfunction of the immobilizer system. Basically it has to do with your registered, chipped key.
