Will there be any airbag deployment etc. I want to explore the possibilities on moving it back a couple of inches.
Disconnect your 12v battery if you do decide to unplug it. That's the closest I can come to actually answering your question. Sorry. EDIT: I believe others have moved the seats back a couple of inches. IIRC, there was a thread from the spring/summer of 2006 regarding this.
I assumed I could remove the 12v small battery, will have to reset window's, presets, etc. afterward. Just wanted to avoid that step.
