Thanks, I always wondered what the "B" was in the Toyotas.

My Honda has the S and the L, which I haven't used much, but I want to get an idea when they can be used to some advantage.
In my old car, an Oldsmobile with overdrive, there was D, 2, and 1. I used to use the 2 or the 1 in situations like snow, especially going uphill. The wheels would spin more slowly, allowing me to navigate through those kind of situations even with all-season tires.
I haven't had the same conditions to deal with yet, but wondered whether S or L might help. I did get dedicated snow tires, which have helped a lot with the (not very deep) snow we've gotten so far.
It's more difficult to understand how these CVTs work.

If you're not part of the solution, you're part of the precipitate.
