On my 2006 I have to pull the ignition switch. It is a 30 amp green fuse. After seven hours, I have to put it back in, run the engine for at least three minutes before I remove it for towing again. I would imagine yours is the same. I also can't drive over 65 mph. There are ways around both of these but that's what is required for my Vue.
