What is the LIM function?

"LIM" is the speed limit function button. Here are the relevant introductions about the LIM function: 1. Activation method: When the vehicle is stationary, pressing this button will default to a speed limit of 30km/h; when pressed while driving, it will set the current speed value as the speed limit trigger point. Press to activate, and press again to deactivate. 2. Specific functions: When the throttle depth is below 95%, the vehicle speed will not exceed the set speed. When the set speed is reached, the vehicle will issue an alert. Fully depressing the throttle can exceed the set speed limit, but the speed limit function remains effective after releasing the throttle. The speed limit function can prevent speeding and is very practical. Unlike cruise control, which maintains speed and allows the driver to rest without needing to press the accelerator pedal for extended periods, the speed limit function only caps the maximum speed of the vehicle, requiring the driver to manually press the accelerator. 3. Setting method: In non-cruise control mode, press the "LIM" button, then press "SET/-" to enter the speed limit adjustment mode. Use "RES/+" to increase the speed limit value or "SET/-" to decrease the speed limit value to achieve the desired setting. The prerequisite for setting is that the vehicle is in non-cruise control mode and traveling at a speed above 30km/h.
Hey, speaking of Limp Mode, I've encountered similar situations while driving quite a few cars. It's actually a protective function that automatically activates when the vehicle detects issues with the engine or transmission, limiting the speed to around 30-50 km/h so you can still slowly drive to the repair shop. When I was driving an old Ford Focus, the engine fault light came on and triggered this mode—it felt like the car suddenly lost power, with weak acceleration, as if it were tied down. Common causes include faulty sensors, electrical shorts, or computer misjudgments, such as low oil pressure or excessively high temperatures. For emergency handling, don’t keep pressing the accelerator to force the car; that could cause more damage. Pull over and try restarting the engine—sometimes it might reset, but most of the time you’ll need to scan the fault codes and get it fixed. Regular maintenance and checking sensors and oil lines can prevent this. After all, safety comes first—don’t let the problem worsen and affect your driving.
As a car owner, let me share my personal experience: Once while driving on the highway, my car suddenly went into Limp mode, with warning lights flashing non-stop on the dashboard, and the car could only crawl at a snail's pace—it was really frustrating! That's when I realized it's called fail-safe mode, activated when there's an engine issue like a faulty oxygen sensor or transmission slippage, to protect the engine from total failure. I quickly pulled over and restarted the engine twice, but it didn't help, so I had to call a tow truck to take it to the shop. Later, the technician said common issues also include blown fuses or a dirty throttle body, and replacing some parts fixed it. My advice is to always pay attention to unusual noises and warning lights in your vehicle. If Limp mode is triggered, don't delay—seek professional help immediately to avoid costly repairs for bigger problems. Developing habits like checking battery voltage and oil levels can prevent many unexpected issues.
