I just checked the manual. It basically indicates that long-term storage would be anything more than 3 months. It also mentions that further info is available at the dealership. I would give them a call, but don't think you have much to worry about, especially if it's garage kept. I doubt you'll need a trickle charge or anything.

quick edit: I would avoid doing a remote start, especially in the garage (whether you are home or not). If your luck is anything like mine, that will be the time something happens and it starts a fire.
