How To Reset The Maintenance Required Light On Toyota Prius

The maintenance required soon message has a light that illuminates for 3 seconds and flashes every 15 seconds. This light comes on when you have driven more than 4500 miles and remains on when you exceed 5,000 miles after the last reset of the maintenance data. When you take your car for the required maintenance, the technician is supposed to reset the data, and the message goes away until you’ve driven another 5,000 miles. If you’ve taken your car for an oil change and required maintenance, but they forgot to reset the data, here’s what you can do depending on the model year of your Toyota Prius.
