it means when the maintenance light is on
The Maintenance Required Light is not the same as the Check Engine Light. The Maintenance Required Light is telling you that there is scheduled maintenance that needs to be performed. It may mean it needs an oil/filter change. To find out what needs to be done look at the maintenance schedule in your owner's manual.

The check engine light comes on when the ECU detects a problem with the emission system. The maintenance required light comes on when some maintenance is required on the vehicle such as an oil/filter change.
