How do I add rinse aid to the dishwasher?

Open the rinse aid dispenser by pressing on the latch of the lid and pulling it open, then add liquid rinse aid until the dispenser is full — do not overfill or allow rinse aid to spill into the air vent hole. Close the lid until it clicks to ensure it is fully sealed, and wipe up any excess rinse aid. The indicator light will go out a few moments after the dishwasher door is shut. (Page 15)
