"B" the same in 2004. Toyota didn't change how it works, but they did make it easier to invoke. Just downward tap the shift-lever anytime you need it. "B" stands for ENGINE BRAKING. It works much like a Jake-Brake on a big rig. The engine is forced to spin even though fuel isn't being fed to it anymore. That causes drag, which results in deceleration assistance. It does not change the gearing in any way. So it doesn't work like 1 or 2 in an automatic. And it does not increase battery recharging. In fact, it slightly reduces it. So don't let the misconception of "B" standing for "battery" spread.

So, no fuel is used when you invoke "B" (unless you're in B and press on the gas pedal)
