Be very careful to remove only the plastic safety piece that holds the inner cap all around. Do not remove anything else because it will not allow you to spray automatically in the car.

To press it and extract the content, you MUST NOT remove the protective ring. It is something that is not stated in the instructions. I, who was in a hurry and removed it, then had to hold it with my hand to empty it, which is dangerous and wrong since most of it spills out.
