What does the wrench symbol on a car dashboard indicate?

The wrench symbol that appears on a car dashboard is a maintenance reminder light, alerting the owner that the vehicle requires servicing. It is recommended to visit a 4S shop or repair facility as soon as possible for maintenance. After servicing, the technician can reset the reminder light. Below is more information about automotive maintenance: 1. Automotive maintenance, also known as vehicle upkeep, refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain components of a car. 2. Automotive maintenance primarily includes servicing the engine system, transmission system, air conditioning system, etc. The purpose is to maintain the vehicle's appearance, ensure normal technical conditions, eliminate potential hazards, prevent malfunctions, and extend the service life.
That day while driving, I noticed a small wrench icon lit up on the dashboard. I've encountered this several times myself. It's actually the car reminding you that maintenance is due, similar to how a phone reminds you to charge it. Different manufacturers set different maintenance intervals - some pop up every 5,000 kilometers while others can last up to 10,000 km. I remember once during a business trip when the light came on, I used the steering wheel buttons to navigate to the maintenance settings page and held the confirm button for a few seconds to clear the indicator. But it's crucial to make sure the maintenance has actually been done before clearing it. Last time my friend took the easy way out by clearing the light himself, only to keep driving with deteriorated engine oil, which cost over 3,000 yuan to fix. Nowadays newer cars are smarter - some directly display the remaining kilometers until next service on the infotainment screen.
Having repaired cars for ten years, I often encounter panicked owners asking about this wrench light issue. The principle is simple: the vehicle's computer counts via the mileage sensor and triggers the reminder once the set value is reached. The key point many don't know is that this light can be reset manually: With the engine off, long-press the dashboard reset button, power on without starting, wait for the maintenance icon to flash, then release and press again—the light will go off in about ten seconds. Note that disconnecting the battery may cause data reset, and some models require a dedicated diagnostic tool. Last week, a German car suffered severe engine carbon buildup after the owner drove 8,000 extra kilometers because the dealership forgot to reset it.
