Porsche Stability Management (PSM)
216
The PSM OFF warning light on the instrument
cluster lights up. The button lights up red.
A warning that PSM is switched off appears on
the instrument cluster.
Information
When braking in the ABS control range, the vehicle is
stabilized even when PSM is switched off. One-sided
spinning of the wheels is prevented even when PSM
is switched off.
However, in exceptional situations it can be advan-
tageous to temporarily switch off PSM:
– On loose ground and deep snow.
– When "rocking the vehicle free".
If the slide/tilt sunroof is open and PSM is disabled,
PSM is switched on again when a speed of approx.
100 mph (160 km/h) is reached.
Information
When PSM Sport mode is active, it is only possible
to switch to PSM OFF mode if PSM was activated
beforehand.
Switching PSM on again
e
Press button .
The PSM is immediately active.
The PSM OFF warning light in the instrument
cluster and the red illumination of the button
go out.
A message that PSM is switched on appears in
the instrument cluster.
ABS brake system (anti-lock
braking system)
WARNING
Loss of control over the
vehicle
The ABS cannot reduce the risk of accidents due to
inappropriate speed.
The increased safety that is provided should not in-
duce you to take greater risks with your safety. The
limits set by the laws of driving physics cannot be
overridden by ABS.
e
Despite the advantages of ABS, drivers remain
responsible for adapting their driving style and
maneuvers to the road and weather conditions,
as well as the traffic situation.
ABS ensures:
– Full steering control: Vehicle remains steerable.
– Good driving stability: No skidding due to locked
wheels.
– Optimal braking distance: Shortening of braking
distance in most cases.
– Prevention of wheel locking: No flat spots on the
tires.
Function
The decisive advantage of ABS lies in the driving
stability and maneuverability of the vehicle in haz-
ardous situations.
ABS prevents the wheels from locking during full
braking on virtually all road surfaces until just before
the vehicle comes to a standstill.
ABS begins to take control as soon as one wheel
shows a tendency to lock.
The controlled braking process is comparable to ca-
dence braking in very rapid succession.
The driver is warned to adapt the driving speed to
the road conditions by a pulsing brake pedal and a
"juddering noise".
If full braking is necessary:
e
Fully depress the brake pedal during the entire
braking operation, despite the pulsing pedal. Do
not reduce the braking pressure.

Multi-collision braking
During an accident, multi-collision braking can help
the driver reduce the risk of skidding and further
collisions during the accident through automatically
initiated braking.
Prerequisites
Multi-collision braking works exclusively:
– During front, side, and rear-end collisions.
– When the airbag control unit detects an appro-
priate activation threshold during an accident.
– During an accident at a driving speed above ap-
prox. 6 mph (10 km/h).
Information
The vehicle is braked automatically by the PSM sys-
tem, provided the hydraulic brake system, PSM and
the electrical system remain undamaged and opera-
tional during the accident.
