Ohh, I had wondered what that tank was for under the hood. Silly me for thinking it was for engine cooling. That's why it was always warm after operation. So it's actually a brewer that is being pre-warmed for instant use. Also, that now means job one is a coffee break, a better idea. Now, if I could just locate that filler so I can use my favorite, 8 O'clock brand.You have to have a Ford dealer turn the feature on. Just go to the dealer and ask the service advisor that you need your Coffee lane departure feature turned on. I think there is a coffee fill tank in the engine compartment somewhere also that they will need to fill. Have them add some expresso also
