According to the handbook I linked to in my post above it does have the demist button, left side of the climate panel?
Every car I driven has this to demist the screen and every car I have driven with climate control I set everything to automatic with the a/c on, never switch it off. I usually press the screen demist on the frosty mornings to clear the screen then switch it off and return to full auto mode. Never get windows misting up.
Make sure the inside of the windows is perfectly clean as dust and muck helps the moisture to form on the surface. Also when was the cabin air filter last changed? Old and clogged filter will often also be damp and this can cause misting of the windows if not routinely changed
