What is the reason for the wrench-shaped malfunction light to illuminate?

This is a maintenance indicator light, which means the vehicle needs maintenance. The specific explanation is as follows: 1. Notes: Different car models from different companies have different maintenance intervals, so please refer to the vehicle's user manual. After maintenance is completed, there is a procedure to reset this maintenance light to zero. If it is not reset, the indicator light will remain on even if maintenance has been performed. 2. Maintenance items: Car maintenance items include changing the engine oil and oil filter, air filter, fuel filter, transmission oil, and tire maintenance. Major maintenance, based on regular maintenance, involves replacing the air filter and fuel filter in addition to the engine oil and oil filter.
What I've learned after 20 years of driving: When the little wrench light comes on, it's basically a maintenance reminder, meaning the car needs an oil change or inspection. Car manufacturers set this icon as a friendly alert based on mileage or time counting—once it reaches the threshold, the light turns on. For example, when I'm commuting long distances regularly, I note that the light might indicate dirty engine oil, a clogged air filter, or the need for brake system adjustments. Ignoring it can lead to increased engine wear, higher fuel consumption, and, in the worst cases, safety risks like brake failure. I remember the first time I saw it, I didn’t understand and went to a repair shop to ask. Now, I schedule maintenance on time and even discuss ways to extend component lifespan. Personally, I believe developing a habit of regular maintenance keeps the car running smoothly.
As a young first-time car owner, I got quite nervous when the wrench light suddenly illuminated shortly after purchase. After researching online, I learned it's a routine maintenance reminder indicating the need for an oil change or other standard services. The vehicle's built-in counter tracks mileage or usage time, automatically activating this warning light when exceeding limits to prompt timely maintenance. Being a novice, I now visit the 4S shop for comprehensive inspections whenever the light appears, preventing minor issues from escalating. I've also discovered that frequent urban driving with short trips tends to trigger this indicator more quickly. Addressing it promptly helps prevent unexpected breakdowns and ensures smooth operation. A friend suggested starting with simple DIY tasks like oil changes, but I prioritize playing it safe for now.
