I am intrigued by this photo of the Leaf's shifter:
It clearly shows a mode labeled "D/B". The "D" obviously stands for "Drive." As for the "B", I am guessing it might stand for "Braking," i.e.
, the ability to "downshift" when descending steep hills. At least this is what "B" stands for on a Prius, as well as on the Mitsubishi iMiEV:
I understand that in the iMiEV, its "B" mode increases the regenerative braking, so I am guessing that would likely be the case in the Leaf as well.
Am I guessing correctly? If so, how does one select "B"? By pulling the knob down a second time? And then how does one resume normal "D" mode? By pulling it down yet again? In other words, do the "D" and "B" modes toggle back-and-forth between "normal" and "strong" regenerative braking?
Also, when the "B" mode is engaged, do drivers see this on the dashboard display? (I have only seen "N" for "Neutral" in photos, but assume that the letter must change when shifting, right?)
I hope that I am correct in my interpretation of "B", as I believe that U.S. regulations mandate that a car must
have a way of "downshifting" for steep declines --lest drivers "ride" their brakes.
