What is the AutoOpen feature and are there any cautions when using it?

AutoOpen automatically opens the door slightly during the drying phase to improve drying results with less energy consumption. Do not try to close the door within 2 minutes of it opening automatically, as this can cause damage to the appliance. For safety reasons — particularly around children, pets, or people with disabilities — you can deactivate AutoOpen through the user mode settings. (Page 13)
