5.4 Releasing Pressure
Once cooking is complete, pressure can be released in two ways:

- Quick Release: Carefully turn the steam release valve to the "Venting" position or use the one-key relief button. Caution: Steam will be released rapidly and is very hot. Keep hands and face away from the valve.
