What is the maintenance light in my 2019 4Runner, and what does it indicate?
The maintenance light in your 2019 4Runner is a feature designed to remind you of the need for regular maintenance. It is typically a dashboard light that illuminates when the vehicle’s computer determines that a maintenance service is due, based on factors such as mileage, time elapsed since the last service, or other conditions.
