Active bonnet
Pedestrian protection system can help to reduce the injury of
pedestrians in case of a front
collision.
When the sensors in the front bumper
detect a certain impact within the
speed range of 25 km/h to 50 km/h, the rear part of the bonnet will be lifted
to reduce pedestrians head injuries.
In addition the front bumper is
designed to reduce leg injuries of
pedestrians.
The active bonnet can be triggered
only once and remains in the raised
position. A message is displayed in
the Driver Information Centre.
Seek the assistance of a workshop as soon as possible, thereby adapting
the driving style, to have the
actuators, hinges and bonnet
replaced.9 Warning
Do not drive with the bonnet
raised.

bumper may appear to be intact,
however, the sensors may be
damaged. Consult a workshop to
verify proper functionality of the
sensors.
The system may not trigger under the following conditions:
● The impact is out of sensor range.
● The sensors are damaged or blocked by accessory parts.
