Don't recall seeing this in the owner's manual or a post....

What happens if I'm running on cruise control (say 75 mph) in gear and I depress the clutch? Does the cruise cut off or does the engine rev up?

 

don't know, try it!

 

No, the cruise will shut off as soon as the clutch is depressed. You can resume that speed as soon as you re-engage that gear. I don't know if you can resume in another gear, but I'll try it when I drive home from work today.
