Zusammenfassung:	A vehicle is provided having an active bonnet and a pyrotechnic actuator configured to lift the active bonnet a plurality of times without having to perform maintenance on the pyrotechnic actuator. The pyrotechnic actuator includes a cylinder having an inlet opening, a first chamber and a second chamber that are separated by a central region; a piston that is configured to be displaced through the central region of the cylinder between a first position in the first chamber and a second position in the second chamber; and a carrier having first and second gas generators each being coupled to the inlet opening. The first gas generator is configured to be ignited to lift the active bonnet a first time, and the second gas generator is configured to be ignited independently of the first gas generator to lift the active bonnet a second time.
