Don't make any noise on a Sunday. For example: don't drill holes in the wall, don't play loud music, don't mow the lawn! It's actually illegal!

Do not cross the street if the traffic light for pedestrians is in red! It is very common in other countries to do so, as you might just check out for cars and ignore the traffic light. It does not work like that in Germany and somebody could even say something about it in not a very nice way

When entering a home remove your shoes at the entrance as it is considered polite to leave dirt outside the house. Unless your host specifically says it is ok to leave your shoes on.
Most people in Germany remove their shoes and wear house slippers or as they say in German "Hausschuh".

Most people take their shoes off when they come into their house, so if you go to someone else's house, be prepared to be walking around on socks!

Try to pay attention about the different trash cans for recycling. Germany takes it very seriously.
