Air bag at startup is just a test light. It will stay on for 3sec or so. If it stays on or flashes - there is a problem with the Airbag system that you (unfortunately) will need to take to the stealership to fix.
As for the solid ABS light - it could be that one of the sensors has gone, or that you are low on fluid. Could also be the ABS CU but lets not speak of that

I suggest taking it to a mechanic or a brake shop who knows what they are doing when it comes to ABS. But a solid light means something is wrong in the system...
