What is the Wrinkle Shield feature and how does it work?

The Wrinkle Shield feature is designed to prevent wrinkles from forming when you are unable to remove clothes from the dryer immediately after a cycle ends. It provides 40 minutes of heat-free, periodic tumbling at the end of a cycle to rearrange and fluff the load. When the Wrinkle Shield setting is active and the Cycle Signal is on, a tone will sound every 5 minutes until the clothes are removed or the Wrinkle Shield period ends. (Page 6)
