How do I use the Precision Dispense cartridge, and how much detergent does it hold?

The Precision Dispense cartridge holds up to 18.5 oz. (550 ml) of liquid HE detergent, enough for up to 36 loads depending on cycle and detergent concentration. To fill it, push back on the tab, lift the fill door, and fill to the 'MAX' line with HE liquid detergent. Insert the cartridge completely into the detergent compartment until it clicks into position, then slide the dispenser drawer in until completely closed. (Page 9)
