Toyota hybrids are designed to give the driver maximum control over the vehicle, including driving dynamics, and this is ultimately the purpose of the ‘D’ and ‘B’ modes that sometimes confuse clients. Put simply, the ‘D’ mode is for normal driving, and ‘B’ mode should be used when you are going downhill.
Source: Toyota. Gear B stands for “braking” in the simplest term. The B gear in the Toyota Prius or any other hybrid car functions as a lower gear that serves a unique function, much like shifting a manual gearbox to a lower ratio on a long downhill route.
What is B gear in automatic?
B can be selected at any time while driving. In the B position the car brakes with the electric motor when the accelerator pedal is released while the hybrid battery is charging. This gives more opportunities for recharging the hybrid battery, since charging also takes place without the driver using the brake pedal.
My experience has been that you can keep B-mode engaged at all times. Above 70km/h (45mph), B-mode is not going to slow down the car aggressively, it behaves more like D-mode. Under 70km/h it starts to feel a bit strong. Under 50km/h (30mph) it is quite strong.

Can I switch from D to B while driving?
Most modern cars thankfully won’t let you switch to some gears while driving to stop any mechanical disasters. For the most part, automatic cars up and downshift for you so you don’t have to worry about it.
How do you use the S and B gear in an automatic car?
What does B stand for in a car?
A car’s “B” gear is the second gear in the transmission. It is also known as the “Brake or Engine Brake” because it provides extra power to the wheels, which is helpful when driving up hills or accelerating from a stop. It is simply an extra gear that some cars have.
What is B in CVT?
The “B” actually stands for “braking”. This mode is specifically for use when a higher level of engine braking is required, such as descending steep hills. “B” mode allows the engine to rev to 3000 Rpm throughout the speed range so a far greater engine braking resonse is felt when letting off the accelerator.
What is D and S in automatic car?
When looking at your gearshift, you’ll see D and S. D stands for regular Drive mode. This is similar to drive mode in other vehicles. The S stands for Sports mode and will engage a few extra features when driving in that specific mode.
S mode provides the best possible performance from your car. It is ideal for use on the track or during high-performance driving conditions.
What does S and B stand for on a gear shift?
The S and the B stand for Sport and Brake on the gear shift as we mentioned above. Each of them has its own function. Beside, there are some other letters on the gear shift such as P, R, N…
Should you drive in D or DS?
DS Mode is more fun than D Mode but in all actuality the D Mode is actually faster even though DS Mode feels like it is faster. When you’re in DS Mode it does react faster at higher speeds for passing because it’s as though you can feel the car shifting gears (even though the CVT is gearless).
Can you shift from D to S while driving?
You can definitely switch from D to S while driving, just don’t do it while pedal to the floor. Even that is probably safe as the computers won’t let it hurt the car, so it will only shift when its safe to do so regardless of what you ask it to do via the lever.
What gear should I drive in?
A good rule of thumb is: higher gears and easy throttle equals less torque and the least amount of wheel spin. Lower gearing and more throttle equals more torque and the most amount of wheel spin. Downhill: Use first gear when driving downhill as a primary source for braking.
If you are wondering, “What does D1, D2, D3 mean in automatic cars?” here’s a perfect explanation for you. D1, 2, and 3 are different gear levels. D 1 is the slowest among the three, while D2 is faster than 1, and D3 is faster than both 2 and 1.
Should I drive in D or D3?
Under normal driving conditions, it is usually best to use the “D” gear selection rather than D3. D3 is not ideal for normal highway driving, as the engine will have a higher RPM at the lower gears and consume more fuel.
Can driving in D3 damage your car?
You would only use D3 while going downhill with a load so you can use your brakes less. Your mileage would be worse since the engine is running at a higher rpm. Only if you did a lot of using D3 would it make any appreciable wear on your transmission.
Does driving in D3 save gas?
Driving the car in this gear than the lower modes means you can have nearly 15% improved gas mileage. In short, the D3 gear utilizes the first three gears in an automatic transmission or locks it on the third gear.
Does D3 make your car faster?
D3 might help you get up to speed more quickly when driving up a hill. A higher RPM means a faster car since D3 prevents the transmission from going into overdrive. Like in any other circumstance, when driving, you don’t want to put too much strain on your transmission.
What happens if you drive in 3?
Yeah, it’s probably fine. When towing things, you usually put it in third to prevent rapid shifting between third and fourth, but it’s still fine to drive the speed limit in most places. A bit of gas millage loss, but other than that, you’re fine.
