When and how do I shift up and down on my 2012 automatic. I want to make sure I don't mess stuff up.
I reccomend reading your owner's manual for the how. Seriously
However, for the when? Look at your RPMs. I'm not sure about you automatic guys, but for my manual I downshift at 2000 and upshift at 2700 RPM, approximately.
