2007 ML. W164 seatbelt question
 

So I was turning left from a side road out onto a main thoroughfare and was paying more attention to the traffic than I was to where's the center divider curb started at the end of the intersection I ended up hitting the center divider curve with my subframe and blew my driver's airbag and lock the rear seat belt since then I've replaced suspension parts the driver's airbag but I was told I need to have the stage one seat belts repaired I pulled all four retractable seat belts out and it looks like only the rear ones are stage 1 the front ones have no electrical contacts going to them
So my question is you don't need to be repaired also or just the back ones and then the computer reset with a scan tool any help would be much appreciated thank you
