When do i use the 2 and L in m automatic gear?

In an automatic transmission, "2" and "L" (Low) are used for specific driving conditions. You should use "2" when you want to limit the transmission to the lower gears for better acceleration and control, such as when driving up steep hills. "L" is used for maximum power and torque, often in situations like towing or driving in very steep terrain or slippery conditions, where you need to maintain a lower gear for more control.
