Porsche Stability Management (PSM).
All 911 models are equipped with
enhanced Porsche Stability Management
(PSM) as standard. PSM maintains
stabilit y even at the limits of dynamic
driving performance. Sensors
continuously monitor the direction,
speed, yaw velocit y and lateral
acceleration of the car. Using this
information, PSM is able to calculate the
actual direction of travel at any given
moment and initiates strategic braking of
individual wheels to prevent you from
deviating from your intended line.
Under acceleration on inconsistent
surfaces, PSM improves traction using
the automatic brake differential (ABD) and anti-slip regulation (ASR) functions.
The result is a high level of driving
stability and safety – and extraordinary
agilit y at the same time.

Adaptive cruise control including
Porsche Active Safe (PAS).
Available as an option in conjunction
with Porsche Doppelkupplung (PDK),
this enhanced version of cruise control
actively regulates the speed of your
vehicle in line with the speed of the
vehicle in front. A radar sensor scans the
road ahead up to a distance of 200 m.
If Porsche Active Safe (PAS) detects that
your vehicle is approaching the vehicle in
front too quickly, the system issues an
audible and a visual warning. Where
necessary, this may be accompanied by
a brief jolt of the brakes and the initiation
of targeted braking. During this process,
any braking by the driver is boosted to
achieve the maximum braking force that
the system is able to provide. With the new 911, coasting is now
possible even while adaptive cruise
control is active.
Lane Change Assist.
New Lane Change Assist, available as an
option, uses radar sensors to monitor
the areas to the rear of the vehicle and
the blind spots on either side. Above a
speed of 9 mph, the system issues a
visual warning signal in the door mirror
panel whenever a vehicle rapidly
approaches your vehicle from behind
or enters one of your blind spots. In
this way, Lane Change Assist improves
comfort and safety, particularly on
motorways. However, the system does
not actively intervene to control the
vehicle and can be deactivated at any
time.
ParkAssist.
Featuring four inconspicuous sensors in
the rear end, the system audibly alerts
the driver to the presence of obstacles
detected behind the vehicle. An
intermittent warning tone increases in
rapidit y as the obstacle is approached.
ParkAssist can be optionally upgraded to
include monitoring of the front end with
four additional sensors. The audible alert
is supplemented by a visual warning in
the central display screen, which shows
a graphical representation of the vehicle
from overhead.
The optional reversing camera facilitates
precise reverse parking and manoeuvring.
Help is provided in the form of the camera

The camera-based speed limit indicator
informs you of speed restrictions and
