Porsche Stability Management (Psm) - Porsche 911 GT3 Owner's Manual

Safety notes!
Your vehicle warranty does not cover use in
competition, racing or track use or other events.
Components and/or parts that fail during racing
or driving events (including Porsche sponsored
events) will not be covered by the manufacturer
new car limited warranty or the pre-owned vehicle
warranty.
Your new 911 GT3 has been developed with
experience gained from the development, testing,
and driving of countless GT vehicles. While
drivable on public roads, the GT3 is specially
equipped for racing on racetracks and is set up at
the factory for the adjustments required for
racing.
The GT3 can be adapted to either the racing or the
street environment. In each case, take into
account that a modern high-performance sports
car is a complex system whose individual compo-
nents are carefully adjusted to work well together.
Interfering in this system is only an option if it can
be guaranteed that all of the components will
continue to work together according to the actual
running conditions. Well-founded Porsche
technical specialist knowledge is necessary for
this. You should seek advice from your authorized
Porsche dealer.
Here, you will receive information about sports
parts available from Porsche, their reliability on
public roads and important maintenance notes.

Please bear in mind that use on race tracks
subjects all vehicle components to considerably
more wear than normal use, making professional
inspection and maintenance after each use a vital
precondition for functioning and safety.
Please use only Original Porsche Parts for your
car. These parts are available from your autho-
rized Porsche dealer, who has expert knowledge
concerning the range of approved parts and will
be pleased to advise you further.
The use of other parts or accessories which are
neither Genuine Porsche Parts nor approved by
Porsche may adversely affect the safety of your
car, and Porsche can take no responsibility for any
loss or damage caused by their use.
Even if the supplier of other accessories or parts
is a recognized supplier, the safety of your car
may still be affected if such items are installed.
Due to the large variety of products offered in the
accessory market it is not possible for Porsche to
inspect and approve every one.
When your Porsche is driven in normal driving
situations on public roads, away from the
racetrack, please note that the use of replace-
ment parts which are not Genuine Porsche Parts,
or approved parts, or the use of accessories not
approved by Porsche may also detrimentally
affect the Warranties relating to your car.
Note again that in no case will Porsche warrant
any parts damaged while racing your vehicle, on
or off the track.
Motor racing
For reasons of safety, the braking system,
steering, running gear, wheels and tires of your
car should be checked after every use on a race
track.
On public highways, the running gear and rear
wing must be in the standard position.
Power transmission
The differential lock, which was designed for use
on race tracks, may make a slight noise when
maneuvering and on tight corners.

Porsche Stability Management (PSM)

PSM should always be switched on during
"normal" driving. This is particularly the case when
the road is wet.
