It flashes the message for 2 seconds and is gone.
I think once, maybe twice in my 78,000 miles I've seen the "Drive to Clean " message, Which will stay lite for as long as the truck needs you to keep driving to finish an Active Regen.
Remember these trucks have two types of Regen, Active when the computer dumps extra fuel down the exhaust to clean the DPF and Passive where anytime you exceed 572°F in your exhaust it will clean what it can. If you do a lot of the type of work that creates higher exhaust temps, your passive regen will do most of the cleaning.
Freeway driving at 70 mph = 470° to 490° temps
Towing at 70 mph = 800+° temps.
So passive regens occur more when you tow or are climbing grades.
