What does the lim button on a BMW mean?

The lim button on a BMW is the speed limit button, which is used for the speed limit function. After setting the speed value, the speed will be limited to a certain value, and the speed will not increase even if the accelerator is pressed, which can be used to prevent speeding. Usage method: Press the lim button once to turn on the lim function, and press it again to turn off the lim function. The specific usage of the BMW lim is as follows: The lim on a BMW car means the speed limit function, and there are two methods to start it: 1. When the vehicle is stationary, press it once, and the default speed limit will be 30. 2. While driving, press it once to record the current speed value as the speed limit trigger point. For example: When driving on a road with a speed limit of 60, press the button when the vehicle speed is between 58-65. When the vehicle speed exceeds this value, a warning will appear on the dashboard. Press the LIM button again to terminate the function. If the vehicle speed exceeds the set speed limit, the system will issue a warning. When reaching or exceeding the set speed limit under conditions such as downhill driving, the active braking mode will not be activated. If a speed limit lower than the current speed is set during driving, the vehicle will coast until the speed is below the limit. Since the system allows exceeding the speed limit under certain special circumstances, the driver can exceed the speed limit as needed, in which case the system will not issue an audible warning.
I was curious about this when I first bought my car. During the time I drove a BMW, I often used the LIM button, which actually stands for speed limiter. It means that after pressing it, you can set a maximum speed limit to prevent speeding. For example, I often drive in the city, and when the speed limit is 60 km/h, I set an upper limit of 65 km/h. The car will then automatically control the throttle to avoid exceeding the speed, which is super convenient. That time on the highway, I almost got fined for speeding, but after getting used to this feature, it felt particularly safe. It's different from cruise control; cruise maintains a fixed speed, while LIM only restricts acceleration. BMW's system is quite reliable, especially when paired with other safety settings like lane assist, helping to avoid accidents. I recommend new drivers try it, especially when driving with kids for added peace of mind. Regularly check if the button is responsive to avoid electronic malfunctions affecting its performance. After driving for five years, this design has been a real help.
As someone who frequently studies car features, I find the LIM function on BMWs to be straightforward and practical: simply press that button to activate the speed limit system, then set the maximum speed. Its principle is to electronically control the throttle, automatically adjusting to prevent the car from exceeding the speed limit, avoiding tickets or dangers. Unlike adaptive cruise control, LIM doesn't maintain acceleration but simply imposes a limit. While driving, such as on steep slopes or slippery roads, it helps maintain stability and is part of BMW's safety package. The interface is usually on the steering wheel, intuitive and easy to use, without the need for complex settings. I've noticed that earlier models had LIM operating independently, but now it's integrated with smarter systems while keeping the core purpose unchanged. Just ensure stable battery voltage for proper functionality and mention it during maintenance.
