BUY SEAT BELT EXTENDERS ON AMAZON.
I tried to put a link but it said I don't have enough posts yet. They come in white, beige, and black. It also helps with the problem with buckling the belt under the armrest. Then when you unbuckle from the extension the chime and light will not come on.
I tried every way offered and this is the only thing that worked.
Downshifting in auto-stick mode - I realized yesterday that you can downshift thru multiple gears by pushing the shifter forward and just holding it. I went from 8th to 5th very smoothly and rather fast with just the 1 motion. I don't think I would actually drive that way but it surprised me that it worked. Anyone else ever notice this? I would be concerned that it would downshift thru too many gears and possibly hurt something.
