In the course of normal driving the driver never needs to use b mode engine braking mode. Check out all of my videos. Toyota have made special provision for engine braking and to activate this you put the mode selector lever in the b position. The prius however has no gearbox in the usual sense of the term.

The b is for engine braking. By a special configuration of the motor generators the engine spins and helps hold back the car just as in a car with a gearbox see how b mode works below. But in the instruction materials supplied with prius now i just bought one sept 2012 one gets owners manuals for the car display audio system and others including a cd for people driving a hybrid for the first time. B mode brake braking does position power prius shifter what may 8 2016 1 use the b position of the mode selector lever in exactly the same circumstances as you would change to a lower gear to slow down a conventional car.

Because the prius has regenerative braking which returns otherwise wasted energy from braking to the hybrid drivetrain a. A prius normally uses regenerative braking to supplement the friction brakes but after a long downhill run the battery becomes fully charged and regenerative braking stops working. Everyone everywhere including my toyota dealer agrees that b gear is used only in long downhills.
