What does it mean when the wrench light comes on in the car?

When the wrench light comes on in the car, it is a maintenance reminder indicator, signaling that the vehicle needs servicing. Generally, manufacturers set this maintenance reminder function to alert owners to perform scheduled maintenance based on mileage or time requirements. The maintenance reminder is a built-in system in the car that tracks the mileage and time since the last service. After each maintenance session, the system resets the mileage and time counters. Car maintenance, also known as vehicle servicing, refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car. It primarily includes maintenance of the engine system, transmission system, air conditioning system, etc., aiming to keep the vehicle clean, ensure normal technical conditions, eliminate potential hazards, prevent faults, and extend the vehicle's lifespan.
That wrench icon lighting up is usually your car reminding you it's time for maintenance. It's like a built-in alarm triggered by mileage or time. I first saw it on my Toyota after driving about 6,000 km, indicating it was time for an oil change, brake pad inspection, tire check, and such. Don't ignore it! Last week, I delayed my visit to the repair shop, and my engine started making strange noises. The mechanic said oil sludge had built up and nearly caused major trouble. It cost me 200 bucks to fix, including resetting the light system. You could try doing it yourself, but I wouldn't recommend it—better leave it to the professionals to ensure safe driving. Developing a habit of recording maintenance can help avoid these issues, like checking the dashboard every time you refuel.
Shortly after I started driving, I encountered the wrench icon, which started flashing and made me a bit nervous, as a new driver unfamiliar with cars. My friend told me it's called the maintenance reminder light, signaling that it's time for regular servicing, like changing the air filter or checking the chassis. When I asked the technicians at the 4S dealership, they explained it's a standard feature in Hyundai vehicles to prevent forgetfulness. Later, I checked the owner's manual to learn how to read the codes myself, but it's best not to tamper with the electrical circuits to avoid mishandling. Delaying maintenance might increase fuel consumption or even trigger other warning lights. Now, I always check it before long trips and schedule maintenance in advance for peace of mind.
