they provide an indication of air bag deploy-
ment.
The vehicle can be deformed considerably, with-
out an air bag being deployed. This is the case if
only parts which are relatively easily deformed
are affected and the rate of deceleration is not
high. Conversely, air bags may be deployed even
though the vehicle suffers only minor deforma-
tion. This is the case if, for example, very rigid
vehicle parts such as longitudinal body mem-
bers are hit, and sufficient deceleration occurs
as a result.
If the restraint system control unit detects a side
impact or that the vehicle is rolling over, the rel-
evant restraint system components are activa-
ted independently of one another depending on
the apparent type of accident. If the system
determines a need for additional protection for
the vehicle occupants, the Emergency Tension-
ing Devices are triggered.

Not all air bags are deployed in an accident.
The different air bag systems work independ-
ently of each other.
How the air bag system works is determined
by the severity of the accident detected,
especially the vehicle deceleration or accel-

PRE-SAFE (anticipatory occupant
protection system)
Introduction
In certain hazardous situations, PRE-SAFE
takes pre-emptive measures to protect the vehi-
cle occupants.
Important safety notes
!
Make sure that there are no objects in the
footwell under or behind the seats when mov-
ing the seats back. There is a risk that the
seats and/or the objects could be damaged.
Despite your vehicle being equipped with the
® system, the possibility of personal
PRE-SAFE
injuries occurring as a result of an accident can-
not be eliminated. Always adapt your driving
style to suit the prevailing road and weather
conditions and maintain a safe distance from
the vehicle in front. Drive carefully.
