There are generally three types of maintenance reminder lights: a yellow oil can icon, a yellow small wrench icon, or direct Chinese characters stating 'Please change engine oil immediately'. When the maintenance reminder light illuminates in a vehicle, it indicates that the car requires maintenance, not that there is a malfunction. The original purpose of the maintenance reminder light is to prompt the owner to visit a 4S shop for servicing as soon as possible. After maintenance is completed, the 4S shop will reset the maintenance light using a diagnostic tool. Below are two methods for setting the maintenance reminder light: (1) Directly setting the mileage, for example, if you want it to illuminate at 5,000 kilometers, then after the current maintenance is completed, set it directly to 5,000 kilometers during the maintenance reset. The light will then illuminate when the vehicle reaches 5,000 kilometers again. (2) Unable to set the mileage, only able to perform a maintenance reset, but the mileage at which the light illuminates is uncertain. The vehicle's computer determines the remaining oil life based on a series of factors such as mileage driven, time, driving conditions, usual load size, etc. When it falls below a certain set value, the maintenance reminder light will illuminate.

I've seen that maintenance reminder light many times. It's a small wrench icon or similar tool symbol on the dashboard. When it lights up, it means your car is due for routine maintenance, which could be an oil change, brake inspection, or other minor services. The vehicle triggers this reminder based on either mileage or time. When it appears while I'm driving, I always promptly schedule an appointment with the dealership or repair shop. If neglected, the car's performance gradually declines - you might notice increased fuel consumption or louder engine noise. This feature is quite intelligent, saving owners from remembering schedules and helping prevent major issues. I recommend keeping an eye on it regularly. After servicing, technicians will reset the light using special tools to ensure proper ongoing operation.

When I first started driving, I was quite curious about this indicator light. It's right in the middle of the dashboard, shaped like a wrench. When it lights up, it means maintenance is due, usually triggered every 5,000 kilometers or so. I didn't know much about cars at first, but I learned: when the light comes on, don't panic—it's not signaling a fault but kindly reminding you to check your car's condition. I usually contact the 4S shop directly, and they reset it during the inspection. Ignoring it might lead to minor issues piling up, like the AC not cooling well or brakes not working smoothly, so I always take care of it. This light has helped me develop good habits, and I think new cars are quite considerate.

The maintenance reminder light is just a small icon that illuminates when it's time for the car to visit the shop. I've thought about its working principle: the vehicle's built-in computer tracks mileage or time, and automatically lights up the reminder when preset thresholds are reached. This isn't an emergency malfunction light, but rather a routine maintenance signal. When illuminated, promptly schedule maintenance items like filter replacements or engine oil system inspections. Technicians can reset it through the diagnostic port. Remember not to ignore it, as delayed maintenance increases wear risks and affects the vehicle's durability.
