You can change from 'D' (Auto) to Manual at any time on the fly, regardless of speed. In Manual mode, '+' moves your gear up (1... 2... 3...) just as if you were changing gears manually in any car. The shift pattern is not an 'H' pattern, however... it's just a forward light push on the lever (or pull on the paddle shifters). The '-' movement in the opposite direction will downshift (3... 2... 1...). Tired of shifting? Slap it in 'D' and relax. At first, you may forget whether you're in Auto or Manual mode, but the consequences are nothing more than a look of embarrassment when you think it should be shifting automatically when you've forgotten that you're in manual mode, or vice-versa. I switch back-and-forth in my drive modes all the time, depending on conditions and what I favor. Have fun with it!
