Can someone give me the quick version of what each mode does and if there is a way to quickly change them? We are granny drivers usually and ECO should be great for us. I'm assuming that is the gas mileage saver. But, there are a few cases (i.e. one freeway entrance by my home that goes quickly) where I need quick pick up. Is there a way to quickly change or do you need to navigate through buttons? I think I only see the xmode as the quickly navigate button. I suppose we can shift to manual and paddle shift but that will take some learning on my end as I only use my shifters on my other car for steep downhills. I have no idea of other modes. Thanks!
