Toyota’s Corolla line of compact cars is among the best-selling in the world. Because of its convenient combination of roominess, fuel efficiency, and safety equipment, this model is ideal for many people. However, the Toyota Corolla’s “B” gear may be unfamiliar to you. Many of us may be apprehensive about the term, but it’s actually quite straightforward.

So, what is it? How does it work to ensure ride safety? What are its benefits? Is it driver-friendly? If you have such questions in mind, read on!

What Is Toyota Corolla B Gear?


What does the “B” in Toyota Corolla stand for? In automatic transmissions, “B” indicates engine braking or a brake.

It is the drive wheel of the automatic speed system. When you release the accelerator, the automatic speed system understands that you are in a neutral position and accelerates slowly.

B gear is a technical term many people find highly unfamiliar and esoteric. However, it is not ambiguous. This brake mode generates power for maximum engine braking when traversing steep inclines or when the vehicle’s speed restriction cannot be controlled.

How Does Toyota Corolla B Gear Work?

The B gear kicks if your regular braking system fails while driving downhill. The Toyota Corolla B gear generates drag on your vehicle. In an automated hybrid car with mechanical and electrical components, the drag force generated will assist you in generating the greatest braking force.

The B gear generates drag force by causing friction between your automobile’s wheels and the road. It aids in slowing down. This frictional force also generates energy, which recharges your automobile battery.

When the gear lever is shifted to B, comparable to L or 1, 2 on some other automobiles, the car will revert to a low gear, braking at a low level, allowing the car to continue downhill without drivers having to strain themselves to brake. However, if the braking system is required to operate continually, it can quickly become heated and useless. As a result, you must use extreme caution when driving on the pass, especially if you are transporting heavy cargo.

Going Downhill

Using B gear might help the car slow down more gradually when descending a slope. More torque and stopping power from the engine is the reason behind this. Because you won’t have to push the brake pedal as often, it will keep the brakes from overheating.

On Uphill Roads

In addition to being employed as a braking mechanism, B gear may also be utilized to assist in the ascent of steeper roadways. This is because the engine will have more torque to propel the vehicle up the slope while it is in this position.

In the Snow or Mud

Using B gear can assist in stopping your wheels from spinning while driving in mud or snow. Again, the Toyota Corolla’s B gear keeps the first gear engaged, indicating that the engine is producing greater torque. This aids in preventing the wheels from sliding and losing traction.

Handling a Major Load

Towing a heavy cargo or caravan is the most common situation in which B gear is used. As the engine doesn’t have to work as hard to keep up with the vehicle in B gear, it experiences less wear and tear.

How to Use the B Gear?

Since you are familiar with most to know about B gear, you can now begin utilizing it. If you want to have the greatest experience possible, follow these steps.

Reduce Your Speed

For safety purposes, you must reduce your vehicle’s speed. While traveling downhill, use lower ratios and reduce acceleration.

Switch to the B Gear

There is a “B” button on the gear shifter’s knob. To switch into B gear, press it. In no way should the shifter be moved.

Adjust Yourself

Your engine will produce a loud revving noise as the B gear engages. It’s crucial to avoid becoming sidetracked by this, especially on risky steep routes. The noise is normal, and the speed of your automobile will decrease.

Shift out of the B Gear

To save gasoline and battery life, shift out of B gear once you are on a level road. You may accomplish this by slowly reversing the gear to D.

How To Properly Shift To “B” Gear?


When changing to “B” gear, bear the following in mind:

  • Fully depress the clutch pedal.
  • Put the “B” position on the gear lever.
  • Slowly let go of the clutch pedal.
  • As needed, depress the gas pedal.

Can you shift from B to D while driving?

While you are driving your Toyota Corolla, you can shift from gear B to gear D. The problem can only arise if you regularly move them around in different positions.

The constant shifting has a negative impact on the components of the transmission and causes their bands to wear out prematurely.

The transmission system’s spinning coupling mechanism, which is responsible for the gears shifting, breaks down and stops working properly, which causes the gears to change.

Pros of B Gear in Toyota Corolla

The B gear is an advanced feature with several advantages for your Toyota Corolla. Some of its benefits are given below.

It provides Extra Torque and Braking Power

Due to its continued use in the first gear, the B gear offers additional torque. As a result, extra braking power is produced, which is beneficial while traveling downhill or pulling a heavy load.

Stability and Control

It improves steering control and stability while reducing collision and free-fall danger. You can activate this option when traveling on slick or rainy roads or hauling large cargo.

Decrease Collision Risk

Safety is one of the essential reasons to use B gear. For example, you can avoid a collision by engaging the B gear when descending a steep hill.

Better for Slippery or Snowy Roads

Driving on icy or snowy roads may be risky. By utilizing B gear, you may lessen the likelihood that the wheels will spin out of control and lose traction. More torque is created while the engine runs in low gear, which aids in gaining traction.

Recharges Hybrid Batteries

Driving downhill with the B gear helps in recharging hybrid batteries. It releases the hybrid motor of your car.

Cons of B Gear In Toyota Corolla

While the B gear is helpful, using it incorrectly results in several disadvantages, which are as follows.

Starns the Engine

Your engine may have a shorter lifespan if the B gear is used frequently. It is crucial to utilize this function when required and to turn it off when you no longer require the added power or stability.

Not Always Necessary

Depending on the situation, you may not need to use the B gear. For example, if you are driving on a flat road with no load, there is no need to engage the B gear.

Reduced Fuel Efficiency

The B gear’s ability to keep the engine in a lower gear can also affect fuel economy. Because of this, the engine must work harder, consuming more gasoline.

May Lead to Damage

Abuse of the B gear might harm the transmission if it is utilized too frequently. It is crucial to utilize this function when required and to turn it off when you no longer require the added power or stability.

It does Not Help in Upward Driving

Toyota Corolla B gear will cause issues while driving up hilly roads or flyovers. Slowing down a car while moving uphill may cause it to backtrack and crash.

Suddenly Lowers the Speed

You should refrain from using the B gear when the car is at a higher speed, as it may cause skidding. Instead, lower the speed gradually while switching to the B gear.
