I have a toyota Yaris 2017. All the gears I have are P,R,N,D,B. I don't know what really the gear 'B' stands for, but i think it means 'Engine break' when going in slopes to avoid using brakes all the time.
Problem is I sometimes forget to change gear 'B' to 'D' when I am accelerating after a slope and go some distance without understanding. I only undertand it when i feel the engine is not accelerating as it used to. So my questions are,
1.What is really gear 'B' stands for?
2.Did I damage my engine or gear box by accelerating for some distances in gear 'B'?
