PRE-SAFE

®
PRE-SAFE stands for "preventive occupant safety"
and is an effective combination of active and passive
safety. The instant that a dangerous, critical driving
situation is detected preventive measures are initiated
to further improve the safety of the occupants.
Triggering mechanisms
• Emergency stop
• Panic braking (new), in which the deceleration
desired by the driver significantly exceeds the
vehicle deceleration that is physically possible, e.g.
on slippery roads, aquaplaning, ice or snow
• Severe oversteer
• Severe understeer
• Critical steering maneuvers at high speeds
(v > 140 km/h) which indicate a scare reaction by
the driver and which may lead to instability of the
vehicle

Action
• Initial motorized seat belt tightening for the driver
and front passenger
• Positioning of the front passenger seat to a more
favorable position in case of a crash, in vehicles
with seat memory, code (275)
• Automatic closing of front side windows and the
panoramic sliding sunroof, code (413), except for a
small gap, to protect the occupants from objects
penetrating the passenger cell and to prevent their
heads or arms from swinging outside through an
opening
If an accident is avoided, the front belts are relaxed
again when the vehicle is back inside the critical limits.
The systems involved can then be restored to the
desired settings.
