What is S and B in automatic transmission?

If you’re driving on twisty country roads and want to keep the RPM up as you wind through corners, the “S” position is where you want to be.

The D1, 2, 3 can be used in place of the brakes.

What does 4 d gear mean in a car?

D normally stands for “Drive,” meaning you can drive with it in that position. I am guessing you have an automatic with four forward gears, and the 4D position means the car will run in the fourth gear in equilibrium after you get up to speed.

low
L stands for “low” gear, which translates to a gear setting of 1 or 2 (if you know how to drive a manual transmission) in most vehicles. When a car is in low gear, the transmission won’t shift normally.
