Porsche Active Safe (Warn and Brake Assist)
195
Preventive occupant protection
function
Seat belt system optimization
When driving off, the front seat belts are gently
tightened in order to ensure an optimal position with
regard to the occupants. Activation is performed
when reaching a driving speed of approx. 20 mph
(30 km/h) or when the seat belts are fastened again.
Preconditioning of the seat belt and passen-
ger compartment
If a potentially hazardous accident situation is de-
tected, the warning assistant and BrakeAssist can
initiate measures to prepare for a possible collision in
order to support the effectiveness of the passive
occupant protection system. For this purpose, de-
pending on the situation, the front seat belts are re-
versibly pretensioned, windows are opened and
(depending on equipment) the roof system is closed
and the adaptive front seat side bolsters are inflated.
Within the system limits, the preventive occupant
protection measures can be activated both during
emergency braking initiated by the driver above a
speed of approx. 20 mph (30 km/h) or through an
automatic brake intervention initiated by the vehicle.
As soon as the detected collision hazard has passed
and a stable driving condition is achieved, the pre-
conditioning measures are ended and existing seat
belt tension is released again.
System limitations
In the case of repeated activation (e.g. in the context
of driver safety training), the belt tension increases
progressively so that it may no longer be possible to
reliably release the belt tensioning. In this case, un-
fasten and refasten the seat belt or deactivate Por-
sche Active Safe.
The seat-belt pretensioner may be damaged follow-
ing an accident. Visit an authorized Porsche dealer.
Porsche recommends an authorized Porsche dealer,
as they have trained technicians and the necessary
parts and tools.
In the event of restricted or switched-off PSM func-
tionality, the preventive occupant protection func-
tions of the warning assistant and BrakeAssist are
deactivated.
