What does the wrench symbol mean in a Jetta car?
2 Answers
Jetta car displaying a wrench symbol is a maintenance reminder function set by the car manufacturer to alert the owner to perform scheduled maintenance at certain mileage intervals. After the maintenance is completed, the maintenance reminder light can only be turned off by following a specific reset procedure. Purpose of the maintenance indicator light: It reminds the driver to perform vehicle maintenance after the car has been driven for a certain mileage. In other words, when the small wrench symbol lights up, it's time to take the car to a 4S shop for maintenance. How to reset the maintenance light: Note that different car manufacturers set different maintenance intervals, so when the small wrench symbol lights up should be based on the vehicle's user manual. After the maintenance is completed, the technician will reset the maintenance light to zero, which means turning it off, through a setting procedure.
That day my Jetta also lit up the wrench icon, which gave me a start. Later I realized it was a reminder for routine maintenance, such as changing the oil, checking the tires and filters. If not addressed in time, fuel consumption would soar, sludge would accumulate inside the engine, and parts would wear out faster. In the long run, it might even break down on the road, costing a fortune and causing headaches to repair. From my personal experience, after delaying maintenance for two weeks, I noticed sluggish acceleration while driving, and upon inspection, it turned out to be overheating caused by old engine oil. Now, as soon as I see the light, I schedule a full maintenance at the 4S shop, including oil changes, brake tests, etc. The technician will use specialized tools to reset the system and turn off the light. Regular maintenance not only prioritizes safety but also extends the car's lifespan, saving future troubles. In short, don’t take it lightly—treat it as a little reminder from your beloved car.
