Porsche Active Safe (PAS)

CAUTION
Impaired PAS detection
performance
A damaged windshield can impair the functionality
of PAS.
e
Visit an authorized Porsche dealer. Porsche rec-
ommends an authorized Porsche dealer, as they
have trained technicians and the necessary parts
and tools.
NOTICE
e Automatic braking intervention from PAS can be
aborted by the driver braking significantly, ac-
celerating, taking evasive action or deactivating
PAS.
e Automatic braking can decelerate the vehicle to
a standstill if necessary. Once the vehicle has
reached a standstill, it is not held permanently by
the brake system - press the brake and resume
control of the vehicle.
e
Be aware that PAS may apply the brakes unex-
pectedly. Therefore, always secure loads to pre-
vent damage and possible injury.
– When towing a trailer, the braking behavior of
the vehicle-trailer combination can be different
from usual during automatic braking due to the
changed mass and the changed braking and
stabilization behavior.
– In the event of restricted or switched-off PSM
functionality (PSM off), PAS is switched off.
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, PAS can initiate measures to prepare for a
possible collision in order to support the effective-
ness of the passive occupant protection system. For
this purpose, depending on the situation, the front
seat belts are reversibly pretensioned, windows are
opened and (depending on equipment) the roof sys-
tem is closed and the adaptive front seat side bol-
sters 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.
WARNING
Limitations of the pre-
ventive occupant pro-
tection function
The preconditioning measures initiated by PAS can
support the functions of the passive restraint
system, but cannot overcome the physical limits.
e
The following points must be observed:
– 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, unfasten and refasten the seat belt
or deactivate PAS.
– If an accident occurs following a PAS interven-
tion situation, the reversible seat-belt preten-
sioner may become damaged.
Go to a qualified specialized repair shop. Porsche
recommends an authorized Porsche dealer, as
they have trained technicians and the necessary
parts and tools.
– In the event of a defect in the reversible belt
tensioner, the preventive occupant protection
measures are only available to a limited extent.
– In the event of restricted or switched-off PSM
functionality, (PSM off) the preventive PAS oc-
cupant protection functions are deactivated.
Distance warning
If Porsche Active Safe detects a safety hazard due to
following too close, the system can warn the driver
in a vehicle speed range from approx.
40 – 156 mph (65 – 250 km/h) by displaying the
symbol on the instrument cluster.
