35Safety
The driver airbag and passenger airbag are
triggered by violent front-end collisions.
They will not be activated by minor front-end
impacts, if the car overturns or by rear-end
and side-on impacts.
Two impact sensors are located on the top
of the front bumper under the painted shell.
These sensors register any vehicle impact
at an extremely early stage. Based on this
information and the central sensor in the
control module, the control module deter-
mines whether airbag deployment is
required. The control module also deter-
mines whether other airbag system compo-
nents should be deployed: seat belt preten-
sioners, inflatable curtains.
Which airbag system components are
deployed depends on a number of factors,
such as the force of the collision and the
angle of impact.
If the impact sensors register forces corre-
sponding to a high speed collision (airbag
stage II activated), the inflatable curtains will
also be triggered. See page 40.
If a fault arises in the airbag system during
a journey, the airbag warning lamp on the
main instrument panel will come on and the
DIC will display:
Airbag malfunction.
