How do I use the Wrinkle Prevent option on my dryer?

Press the Wrinkle Prevent setting to activate up to 120 minutes of heat-free, periodic tumbling at the end of a cycle, which helps prevent wrinkles from forming if you cannot unload the dryer promptly. You can stop the Wrinkle Prevent setting at any time by pressing the Wrinkle Prevent button again or by opening the dryer door. Note that for the Wrinkle Control Cycle, the Wrinkle Prevent setting is preset to ON. (Page 24)
