The wrench symbol displayed on the car dashboard is a maintenance reminder function set by the manufacturer to alert the owner to perform maintenance after driving a certain mileage. When this light stays on for a long time, it's time to go to the 4S shop for maintenance. Different car models from different companies have different maintenance intervals. After the maintenance is completed, there is a reset procedure that needs to be followed to reset the maintenance light. If it is not reset, the indicator light will remain on even after maintenance is performed. Car Maintenance: Car maintenance refers to the preventive work of regularly inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. Minor Maintenance Content: Minor maintenance generally refers to the routine maintenance items performed at the manufacturer's specified time or mileage to ensure vehicle performance. It mainly includes changing the engine oil and oil filter.

My Civic has been running for almost a decade, and I've seen that wrench icon on the dashboard many times—simply put, it's the maintenance reminder light. It means the car is due for routine service, like an oil change or filter check, usually calculated based on mileage, lighting up automatically every 5,000 kilometers or so. I usually check the odometer reading to confirm the mileage before heading to the dealership or my regular repair shop for a quick service—nothing to worry too much about. Ignoring it might lead to minor issues like increased engine noise or higher fuel consumption, but timely action keeps things fine. The design is quite thoughtful, helping owners develop regular maintenance habits, saving both money and hassle. If you don’t have a regular service record, check the owner’s manual for the maintenance schedule to avoid overdue servicing.

I just bought a Civic not long ago, and one day while driving, a wrench symbol popped up on the dashboard, which made me so nervous that I immediately went online to check—it turned out to be the maintenance indicator light. It signals that the vehicle is due for routine service, such as an oil change or filter replacement, which the system schedules based on mileage or time. I remember the first service light came on after 5,000 kilometers, and the technician at the shop handled it easily without costing much. New drivers often mistake it for a malfunction, but it's actually quite common and something you'll encounter frequently after a few years of driving. My advice is not to guess randomly; instead, check the details in the user manual or directly schedule maintenance to prevent minor issues from turning into major repairs. For safety, get timely inspections to ensure the engine runs smoothly, giving you more peace of mind on long trips.

Working at a dealership, we often address this question. The wrench icon on a Civic is the maintenance reminder light, triggered automatically by the onboard system when mileage or time intervals reach service points. It indicates the need for basic services like oil changes and brake fluid checks to prevent excessive engine wear. As part of routine maintenance, simply visit the shop for a quick reset procedure if the vehicle shows no issues - it takes just minutes. Avoid DIY attempts as incorrect procedures may affect vehicle condition. Address it promptly to prevent steep repair costs later.
