Is the srs red light on a dashboard mean big problems?

If the "SRS" light is on on your dashboard, then chances are you need to replace the fuse that relates to your SRS (Safety Restraint System - airbags to you and me). Find the fuse panel and the SRS fuse, then examine it for burns. If it looks black or dark brown as if its burnt, then it needs replacing. If there isn't a fuse there, then you should probably buy one if you want your airbags working.

Hope this helps!
