To glide in the HSD vehicles, it is really just a matter of letting the engine shut off by taking your foot off the accelerator and then putting enough pressure on the accelerator to stop the regen arrows. If you put too much pressure on the accelerator, you will get assist arrows. If you've tried this, you probably already know that it is very tough getting the "black screen" (no arrows). Apparently, it is difficult in all of the Toyota HSD vehicles except for the Prius II. The easiest way around this is to just shift to Neutral once the engine is off. This just creates an electrical disconnect with the electric motors/generators such that they cannot assist or charge.

When shifting back into Drive from Neutral, you will not notice any transition at all. This is not a true neutral as you would experience in a traditional automatic transmission. With the Toyota HSD, there is no problem shifting back and forth between N and D. You do not even have to press the lock release button when shifting back and forth between N and D.
