What does the car check button mean?

Car check button means inspection, this button is the self-check button, press it and the trip computer display will show corresponding self-check information, including some maintenance reminders such as the remaining distance until the next service. If there are any fault codes in the vehicle, relevant prompts will also appear. If "check" appears on the car dashboard, it means the engine needs inspection and you should immediately go to a 4S shop or repair shop for check and maintenance. According to different power sources, car engines can be divided into diesel engines, gasoline engines, electric vehicle motors and hybrids, etc.
I remember when I first bought my car, I also wondered what this CHECK button was all about. Actually, that small button near the steering wheel is usually for manually checking your car's status. For example, pressing it before starting the engine will make the dashboard display warning lights to tell you if the oil level is sufficient or if coolant needs to be topped up. As an experienced driver who's driven several car models, I've noticed some Japanese cars use this to check tire pressure, while some German cars link it to the engine self-diagnosis system. If you press it and lights come on, don't panic—it's mostly just a reminder for maintenance or part replacement. Ignoring it long-term might let small issues escalate, affecting your car's lifespan. So I recommend making it a habit to press it occasionally, especially before long trips for a quick check. This way, you'll have peace of mind and won't need to worry about unexpected breakdowns delaying your journey.
In our repair trade, that CHECK button is truly a driver's ally. It activates the vehicle's diagnostic function, making the car report its own faults. When pressed, the system reads sensor data - whether it's low battery voltage or abnormal exhaust temperature - and flashes warning symbols directly on the dashboard. I've handled numerous cases where drivers discovered minor issues by pressing the check button, preventing major engine overhauls due to overheating. The key is understanding it's not just for show: when integrated into a multifunction display, this button can also toggle between other information displays. A simple press during daily driving helps prevent problems, far better than emergency measures when warning lights come on.
