The 2006 Toyota Avalon uses a maintenance reminder system that alerts the driver when it is time for regular maintenance to be done. When the computer determines that service is due, the message is illuminated on the control panel until it is reset. A Toyota dealer will reset the service reminder light when they do scheduled maintenance. If you maintain your Avalon yourself, you should manually reset the maintenance required light so it can accurately determine when the next service is due.
