It seems that your car had several important services made and it has a low mileage. That's good.
Here are some first ideas that comes to my mind.
The list would be endless but these are
some important things
which should be taken care before long road trips:
- Spare tire release mechanism is working
- Spare tire pressure around 2.5 or 2.6 bars
- Scissor jack and tire change tools available in car
- Essential tools in a toolbox in the car
- 1 liter LHM, 1 liter engine oil
- First aid bag and traffic jacket (reflective jacket) for you and for each passenger
- Green card for your car from your insurance company
- Check beforehand if you need vignette (road tax sticker) for the countries you'll visit
- Even if you have a Navigator keep a paper map in the car
Edit: For road tolls and vignettes you can check this link

My favorite route planning site:

You can select/deselect options like,
*) Favour highways, *) avoid tolls, *) avoid vignettes and etc.
I never try to teach anybody on the road, especially in abroad countries because I have to
keep in mind that I am just visiting their country and they live there. This advice I read
somewhere which I liked very much and always keep it in mind.
