Active bonnet (pedestrian protection)
Operation of the active bonnet (pedestrian
protection)
In certain accident situations, the actuation of
the active bonnet reduces the risk of injury to
pedestrians. The rear area of the bonnet is
raised by approximately 80 mm.
After being triggered, the active bonnet remains
in the raised position. Limited visibility due to
the raised bonnet cannot be ruled out.
After the active bonnet has been actuated,
pedestrian protection may be limited.
Have the full functionality of the active bonnet
restored immediately in a qualified specialist
workshop.
If necessary, adjust your seat position and drive
carefully to a qualified specialist workshop. If a
safe continued journey is not possible, contact a
qualified specialist workshop.
