What does the wrench symbol behind ln5p mean?

This is a reminder that the maintenance mileage has been reached. To clear the wrench symbol, press and hold the small button on the lower right side of the dashboard, then turn the key to the ACC position (power-on position) and wait for 3 seconds. After turning off the power, turn the key to the ACC position again, and you will notice that the maintenance reminder wrench symbol has been cleared. More related information is as follows: 1. Note: After completing this operation, if you need to disconnect the battery, you must lock the vehicle and wait for at least 5 minutes; otherwise, the reset will not be recorded by the control unit. 2. Resetting the trip odometer (daily odometer): Turn on the ignition switch, and hold down the trip odometer reset button on the instrument cluster until the displayed mileage returns to zero.
I've been driving for ten years, and the wrench light on the dashboard is all too common. This icon is the maintenance reminder light, just like a phone alarm. Manufacturers preset the maintenance intervals in the onboard computer, typically flashing every 5,000 to 10,000 kilometers. Last time I drove a Hyundai, I encountered this issue—simply accessed the system reset via the steering wheel menu button. The specific operation is to power on without ignition, press and hold the TRIP button on the dashboard for 5 seconds, and release when the wrench flashes. However, it's best to have actually changed the oil and oil filter before resetting. Last time, a friend reset it and kept driving, only to end up with engine sludge and a costly repair of several thousand dollars. Driving with this light on for 200-300 kilometers is fine, but going too long can damage the car.
From a mechanic's perspective, the wrench light coming on falls into two scenarios. If it lights up right after maintenance, there's a 90% chance the service data wasn't reset—just check the manual for reset steps. If it lights up when maintenance is due, don't delay! Focus on checking engine oil life, especially for cars with start-stop systems, as frequent starts consume oil rapidly. Last week, an Elantra owner who ignored maintenance for a month ended up with cylinder scoring. Trigger mileage varies by model: German cars typically light up at 7,500 km, while Japanese/Korean models often at 5,000 km. DIY reset method: With the engine off, hold the trip reset button, turn ignition to ON (don't start), wait 10 seconds, then release—if the wrench flashes three times, it's successful. The reset button is usually on the right side of the instrument cluster.
We female car owners are most afraid of random warning lights on the dashboard. The first time I saw the wrench symbol, I panicked too. Later, my husband explained it was just a maintenance reminder, similar to the filter replacement alert in a beauty fridge. Basically, the car's computer calculates when you need an oil change and lights up this thoughtful reminder. The reset procedure is foolproof: First turn off the engine, press and hold the small cylindrical button (ODO button) on the dashboard, then turn the key to power on without starting the engine. Release the button when the wrench symbol starts blinking. Last year when my Elantra was serviced, the technician forgot to reset it, and I fixed it myself using this method. But remember - only reset it if maintenance was just performed, otherwise you might miss the oil change window and damage the engine.
