What to do after airbag deployment?

What is your question?

I was involved in a minor front end collision in my 2007 328i, resulting in the steering wheel and passenger airbags to deploy. the damage sustained was relatively minor, with only the front bumper and hood being bent slightly. I have I have already replaced both the steering wheel airbag and the passenger dash airbag. The airbag and seatbelt symbols are still lit up on the dash A few odd things to note: before the crash, it had already appeared that the passenger seatbelt had already had the pyrotechnic device that causes it to become shorter, activated. It was already visibly much deeper than the driver side one, which still even after the accident did not detonate is in normal condition. Also, my car does start regularly so I am assuming the battery pyrotechnic device did not go off on there either. Pretty much I just want to know what I needed to do in order to get both the symbols off my dash and make sure my airbags do deploy and the system is working as it should?
