The “B” creates something called “engine braking,” which mimics the behavior of a traditional transmission: It fakes a downshift to slow the Prius if it’s descending a hill. Why? To keep the brakes from being overloaded if you’re on a long, steep grade.
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.
What does B stand for in automatic transmission?
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.
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 is B in automatic transmission mirage?
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 does the letters mean on automatic transmission?
You’ve no doubt noticed that most vehicles have a gearshift control with the letters “P, R, N, S” and “L.” These all indicate different states for your transmission and correspond to various operational modes. P stands for park. R stands for reverse. N stands for neutral. D stands for drive.
What is low gear used for?
Low gear is used when you want the engine power high and the vehicle speed low. This limits stress on your brakes while allowing you to take advantage of your car’s full power in situations like towing and hilly driving.
Driving speed in 4×4 low should never exceed 10mph since the surface conditions are usually low traction, rocky, steep, and uneven surfaces that require low-speed control. 10mph is the maximum recommended speed to drive in low range on technical off-road tracks.
Which gear is the fastest in a car?
The gears determine the amount of power available from the engine. First gear provides the most pulling power but the least potential for speed, whilst fifth gear which provides the least pulling power allows the greatest range of speed.
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.
What gear should I drive in highway?
Most of the time, once you get up tofreeway speed, your manual shift is in its highest gear and you can leave it there. If, due to traffic or general slowdown, you have to reduce speed, you’re at an advantage driving stick shift. It’s easier and more natural to shift to a low gear than with an automatic.

In fact, you should always use the highest gear you can because its more economical. If you are stopping, you don’t change down gears at all – brake down, clutch down, when you stop handbrake on, first gear and ready to go again.
Should I put my car in neutral when stopping at a red light?
Never put your vehicle in neutral at traffic lights
You will be shifting gears every time to meet a stop light, subjecting them to unnecessary wear. You may have to replace them sooner than you thought. Avoid all this by letting the brakes do their job: leave the engine in drive and step on the brakes at the stoplight.

FAQs:
How quick can you burn out a clutch?
The clutch is subjected to constant friction, so it is unsurprising that it will wear out eventually. You may find that your clutch lasts 10,000 miles before you need to get a new one or you could drive 150,000 before it gives up.
Do you hold the clutch while stopped?
#1 Don’t Keep Your Car In Gear When You’re At A Stop Light. Why It’s Bad: Your clutch will suffer from unnecessary wear and tear.
