To clear the maintenance required code on a 2005 Acura MDX, turn the ignition to the "ON" position without starting the engine. Press the gas pedal three times within five seconds. This action should reset the maintenance light. Finally, turn off the ignition, then start the engine to confirm that the maintenance light has been cleared.
Check your maintenance manual. It's in there.

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.
