What does the LIM button on a car mean?

The LIM button on a car stands for the speed limit function. Pressing this button when the vehicle is stationary activates the speed limit function. Below are detailed explanations about the speed limit function: Overview of the Speed Limit Function: The speed limit system was first introduced as a standard feature in the European-spec F10. This system can restrict the vehicle speed between 30-230 km/h. When the speed is below the set limit, the vehicle operates normally. Similar to traditional cruise control systems, the speed limit system uses the engine control system and automatic transmission control system to regulate speed, effectively reducing the torque output requested by the driver. Exceeding the Speed Limit: If the vehicle speed exceeds the set limit, the system will issue a warning. In situations such as downhill driving where the speed reaches or exceeds the set limit, the active braking mode will not be engaged. If a speed limit lower than the current speed is set during driving, the vehicle will coast until the speed drops below the set limit.
As a seasoned driver with over ten years of experience, I immediately recognize the LIM button as the abbreviation for the speed limiter function, commonly found on the steering wheel or stalk. This feature is incredibly practical—it allows you to set a maximum speed limit, such as 120 km/h on the highway, and the car will automatically prevent you from exceeding it. I often use it on long trips to avoid accidentally speeding and getting tickets, while also maintaining steady driving and reducing sudden acceleration. It’s a major plus for safety, especially in areas with speed cameras or when driving fatigued. Setting it up is simple: press the LIM button while driving, then adjust the speed using the controls. The key difference from ACC cruise control is that it doesn’t manage following distance—it only limits speed. From personal experience, it’s most commonly used in European cars like Volkswagen or BMW, and it’s great for beginners or young drivers to develop good habits. Overall, it’s a smart little driving assistant that helps me save both peace of mind and fuel.
A young friend who just got their driver's license asked me about the LIM button, which stands for the speed limiter function. I can share: while driving, press it and set a speed limit like 80 km/h for urban areas, and the car won't let you exceed it. It's especially suitable for beginners like us, eliminating the need to constantly watch the dashboard, avoiding tickets, and ensuring safety. Using it makes driving feel more relaxed, much simpler than adaptive cruise control. I also find it particularly stable on curves or rainy days, reducing accidents. The operation is very intuitive—just check the manual, and you'll understand. Many modern cars have this button. Long-term use helps develop disciplined driving habits and even saves a bit on fuel. I recommend trying it more to make driving both cool and reliable.
