Electric parking brake.
The electric parking brake, which you
can activate and deactivate manually,
releases automatically as you pull away.
With the hill-
hold function, you can
pull away without ever rolling back.
The system automatically detects when
the vehicle has come to a halt on an
uphill gradient requiring intervention.
PSM then maintains the brake pressure
at all four wheels to prevent the vehicle
from moving in the opposite direction.
Airbags.
The 911 Carrera models offer advanced
airbag technology in the form of full-size
driver and front passenger airbags, which
are inflated in t wo stages depending
on the severit y and t ype of accident (e.g.
frontal or offset frontal). In less serious
accidents, the airbags are only partially
inflated, thereby minimising discomfort
to the occupants. In addition to the central airbag control
unit on the transmission tunnel, a pair of
impact sensors are located near the
headlights. This allows a crash to be
detected and evaluated not just sooner,
but with even greater accuracy.
Porsche Side Impact Protection
System (POSIP).
Coupé or Cabriolet, the 911 models
are equipped as standard with the
Porsche Side Impact Protection System
(POSIP). It comprises side impact
protection elements in the doors and t wo airbags on each side. An integral
thorax airbag is located in each seat side
bolster, while the door panels each
contain an upwards-inflating head airbag.
Each thorax airbag has a volume of
10 litres and each head airbag 15 litres,
ensuring excellent protection in the event
of a side impact.
Cabriolet roll-over protection concept.
Despite their low weight, the 911 Carrera
Cabriolet models have exemplary
torsional rigidit y and flexural strength.
Body flexing is minimal even on irregular
road surfaces.
Increased protection is provided by
an automatically deploying roll-over
protection system if the car were to
overturn. Two spring-loaded roll-over
bars are neatly incorporated behind
the rear seats. The roll- over sensor
continuously monitors the car’s pitch
and roll, contact with the road, as
well as lateral and longitudinal forces.
If the car were to overturn, the roll- over
bars would be deployed instantly.
