Hi, I have a 2013 Equinox and want to know the Torx bit size for the seats. As well, from my understanding, I am able to simply tilt the seat forward. I don't want to actually remove the seats, I just need to be able to clean the carpet in those so dirty, but so impossible to get to areas next to the seats. I'm concerned about the air bag sensor. Am I able to disconnect it? Should I simply disconnect the battery? Thanks.
