What is Active Bonnet (Pedestrian Protection)?

Sensors in the bumper detect impacts. Pyrotechnic actuators raise the bonnet. It reduces head injuries. The system is designed to work only in a certain speed range typical of urban collisions with pedestrians. If the bonnet has deployed, a warning appears and the bonnet usually stays slightly raised. Workshops must reset or replace the actuators and check the sensors.

How it works

The raised bonnet absorbs impact energy.

Why it matters for your car

Actuators must be replaced after deployment. Warnings show faults.
