Outside the dangerous area, ideally beyond the crash barrier, unpack and fully unfold the warning triangle.

Depending on the design, twist the two lower bars in the middle until they form a cross, or fold out the four feet - 2 each at the bottom corners of the triangle - forwards and backwards until the warning triangle can be set up stably.

Above the base are the three red bars. Two of them can be pulled up and locked together to form the legs of the triangle. The plastic inner film folds open automatically.
