What does it mean when the maintenance required light stays on in a 2009 Scion TC?

When the maintenance required light stays on in a 2009 Scion TC, it typically indicates that the vehicle is due for a scheduled maintenance service, such as an oil change or tire rotation. The light is usually turned off after the service has been performed, but it can also remain on if there is a problem with the vehicle that needs to be addressed.

In some cases, the maintenance required light may stay on even after the scheduled maintenance has been performed. This can happen if the light has not been properly reset or if there is still a problem with the vehicle that needs to be fixed. If the light remains on after the maintenance service, it is recommended to have the vehicle inspected by a qualified mechanic to identify the cause and have the necessary repairs performed.
