What does M1 and M2 mean in an automatic transmission?

[CarmenDella]

In an automatic transmission, M1 refers to the first gear in manual mode, and M2 refers to the second gear in manual mode. M1 is typically used for normal starts or climbing steep slopes, with speeds around 10 kilometers per hour. M2 is used for accelerating after starting, driving at low speeds near other vehicles, or climbing steep slopes, with speeds around 20 kilometers per hour. You can switch directly between M mode and D mode without any time or RPM restrictions. The transmission will automatically match the appropriate gear based on the real-time speed. When in M mode, the dashboard will display the current gear, and you can shift up or down by pushing or pulling the gear lever. If the gear is in D mode and you want to overtake, the speed won't increase rapidly even if you press the accelerator hard, as the transmission will still shift up sequentially, resulting in a slower response time. However, if you switch to M mode, the vehicle can utilize the high torque of a lower gear to accelerate instantly when the driver presses the accelerator, allowing for quicker and safer overtaking maneuvers while saving time.
