Summary:
If you’ve noticed a letter “B” on your gear shift and wondered what it means, it’s a setting mostly found on hybrid vehicles. Like those from Toyota and Honda. Unlike the familiar P (Park), R (Reverse), N (Neutral), and D (Drive) settings common to most cars, the B mode serves a unique purpose related to braking and energy efficiency.
In hybrids, the B stands for “Brake” or “Engine Braking” mode. This mode increases regenerative braking, which slows the car while recharging the hybrid battery. This process not only reduces wear on your brake pads but also conserves energy. Energy that would otherwise be lost during deceleration. Essentially, it uses the car’s engine to help slow down the vehicle more effectively than standard low-gear modes in non-hybrid cars.
You should use the B mode primarily in stop-and-go traffic or when driving downhill. By increasing the deceleration effect when you lift off the accelerator, it reduces the need to frequently apply the brakes. Thus providing smoother and safer control. Toyota also recommends using B mode when towing. It offers additional braking assistance and better control when descending with a heavy load.
However, the B mode isn’t intended for everyday driving. Using it all the time can make your hybrid slightly less fuel-efficient because it prioritizes engine braking over coasting, which uses less energy. Understanding when and how to use this gear can improve your driving experience, save wear on your brakes, and maximize the efficiency of your hybrid vehicle.
