Not specifically to your vehicle, but the Instructions should be in your owners manual or you can find the procedure online with a little searching.
Yeah I tried on line and looked up the owners manual seems like the 2012 model has to be done by the dealership. Just thought there might be a service tech.out there that could help. So I could save a buck
check e bay believe it or not ! a savvy service tech will be selling the info from home for what the market will bare, maybe they stopped those possibilities [the mfg.] just for that reason though. Why new can be worse than what was traded toward it lol
