How to Use B Mode in your Toyota Hybrid
If you drive a Toyota Hybrid like the RAV4, Corolla, or Yaris Cross, you’ve likely noticed the “B” on your gear selector. But what does it actually do? And when should you use it? Here’s everything you need to know about B mode and how to get the most out of your hybrid drive.
What is B Mode?
B stands for Brake or Engine Braking mode. Unlike a traditional low gear in a petrol car, B mode in a hybrid increases regenerative braking, which slows the vehicle down while recharging the hybrid battery. This helps reduce wear on your brake pads and captures energy that would otherwise be lost when decelerating.

Top Benefits of B Mode in Your Toyota Hybrid
Enhanced Control on Descents
B mode increases engine braking, helping to control your speed without constant brake pedal input—perfect for steep hills or long descents
Reduced Brake Wear
By relying more on regenerative and engine braking, B mode reduces the strain on your physical brake pads, helping them last longer.
Regenerative Energy Recovery
When B mode slows your vehicle, it sends more kinetic energy back to the hybrid battery, helping to recharge it more efficiently during deceleration.
Improved Safety in Stop-Start or Hilly Traffic
In slow, hilly traffic, B mode can help prevent overuse of the brakes while giving you smoother, more consistent deceleration.
Better Towing Support (Where Applicable)
In hybrid models rated for towing (e.g., RAV4 Hybrid), B mode can offer additional control and braking assistance when descending with a load.
How to Activate B Mode
One.
Switch to Drive (D) like normal
Two.
Shift the lever down again to B.
Three.
You’ll feel the difference—your car will begin to slow more noticeably when you ease off the accelerator.
When Should You Use B Mode?
B mode is best used in specific driving conditions, such as:
- Going downhill: It helps control your speed without overusing your brakes.
- Stop-start traffic on slopes: Useful when you need extra resistance to help hold the car’s speed without constant braking.
- When towing (where permitted): B mode can help reduce strain on your brakes on descents.
Tip: B mode is not for everyday flat-road driving—it can make your hybrid slightly less fuel-efficient if used all the time, as it prioritises engine braking over coasting.
