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 racingFor 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 transmissionThe 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.

Operation, Safety
63
The previously selected PASM mode is always
activated after the engine is started.
There is no automatic return to Normal mode after
the ignition is switched off.
PASM makes two running-gear setups available to
the driver: “Normal” and “Sport”.
The selection is made via a button on the center
console.
When in Normal mode the running gear is in a
basic setup for roads and circuits with “irregular”
surfaces.
Sport mode provides a shock-absorber setting
for particularly high driving dynamics (e.g. on level
circuits).
The variable suspension system selects the appro-
priate damping level for each wheel according to
the situation and conditions of driving.
Example:
If the vehicle is driven in a very sporty manner in
Normal mode, PASM automatically adapts the
shock-absorber behavior to the driving situation
accordingly.
Switching on PASM Sport modefPress PASM button in the center console.
When PASM Sport mode is switched on, the
light-emitting diode in the button is lit up and a
message is shown on the on-board computer.Switching off PASM Sport modefPress PASM button in the center console.
The light-emitting diode in the button goes out
and the on-board computer displays a
message.
Dynamic Engine Mounting (PADM)The dynamic engine mounting with variable
damping is a system for improving driving
dynamics and enhancing driving comfort.
Depending on the driving situation, the ideal
mounting stiffness and damping is automatically
selected in a range between an almost rigid
connection of the engine to the body (improved
driving dynamics) and a decoupling of the engine
from the body (improved driving comfort).Warning messageDynamic engine mounting faults are indicated by
a warning message on the on-board computer.

of cranking:
fWait about 10 seconds before engaging the
starter again.
fWhen starting the engine, be ready to drive
immediately.
Drive vehicle at moderate speeds and avoid
engine speeds above 4,200 rpm during the
first 5 minutes.
fDo not let the engine idle to warm up.
Danger!
Engine exhaust fumes have many compon-
ents which you can smell. They also contain
carbon monoxide (CO), which is a colorless
and odorless gas.
Carbon monoxide can cause unconscious-
ness and even death if inhaled.
fNever start or let the engine run in an
enclosed, unventilated area.
It is not recommended to sit in your car for
prolonged periods with the engine on and the
car not moving.
An unattended vehicle with a running engine
is potentially hazardous.
If warning lights should come on to indicate
improper operation, they would go
unnoticed.
fNever leave the engine idling unattended.
Risk of fire due to hot exhaust system.
fDo not park or operate the vehicle in areas
where the hot exhaust system may come in
contact with dry grass, brush, fuel spill or
other flammable material.
fIf your car catches on fire for any reason, call
the fire department.
Do not endanger your life by attempting to put out the fire.

Practical Tips, Emergency Service

Danger!
Risk of serious personal injury or death.
Driving the vehicle with low tire pressure
increases risk of a tire failure and resulting
loss of control. Furthermore, low tire
pressure increases rate of wear of the
affected tires.
fCheck tires – including sidewalls – regularly for
foreign bodies, nicks, cuts, cracks and bulges.
fAfter driving off road, examine tires for signs
of damage such as cuts, tears, bulges or
foreign objects stuck in the tread. Replace a
damaged tire if necessary.
fCross curb edges slowly and at right angles if
possible.
Avoid driving over steep or sharp curbs.
fIn cases of doubt, have the wheel (particularly
the inner side) checked by an authorized Porsche dealer.
Tire replacements If in doubt, contact your authorized Porsche
dealer.
Use only tire makes and types approved by
Porsche.
If you do not use a Porsche recommended
replacement tire, make sure that you
purchase your new tires from a reputable tire
dealer and that the dealer complies with all
manufacturers warnings for those tires.
Only tires with the same make and with the
same specification code (e.g. “N0”, “N1”...)
can be mounted.
Before mounting new tires, check with your
Porsche dealer about the current release
status.
Use tires with “ZR” quality standards. There
are currently no standards concerning tire
strength at speeds above 150 mph (240 km/h).
Tires should be replaced no less than on one axle
at the time.
Only tires of the same make and type must be
used. Mixed tires are not permissible.
Initially, new tires do not have their full traction.
You should therefore drive at moderate speeds
during the first 60 - 120 miles (100 - 200 km). If new tires are installed only on one axle, a notice-
able change in handling occurs due to the different
tread depth of the other tires.
This happens especially if only rear tires are
replaced. However, this condition disappears as
the new tires are broken in.
fPlease adjust your driving style accordingly.
Installation of new tires should only be done by a
qualified tire technician.
Valves
Please observe the installation and replacement
instructions for valves.
fUse only genuine Porsche metal valves.
fProtect the valve inserts against soiling with
valve caps.
Soiled valve inserts can cause a gradual loss
of air.
fUse only plastic valve caps.

Removing and storing tires fAfter changing, adjust tire pressure and torque
wheel bolts diagonally to 370 ftlb (500 Nm).
Tires must always remain on the same side of
the vehicle.
When wheels are removed, the direction of
rotation and position of each wheel should be
marked.
Example
FR (front right), FL, RR and RL.
Wheels must always be fitted in accordance with
their marking.
The perception that tire durability and perfor-
mance are immune to the effects of storage and
age is unfounded.
Chemical additives, which make the rubber
elastic, lose their effectiveness in the course of
time and the rubber becomes brittle and cracks.
Therefore, the tires should be inspected from
time to time. Note
Under no circumstances should tires older than
6 years be used on your Porsche.
The age of the tire can be obtained from the “DOT”
code number. If, for example, the last four
numbers read 1209, then the tire was produced in
the 12th week of 2009.
fStore tires in a cool and dry place.
Snow tires For a better grip on snow and ice, use radial M+S
tires with studs.
Check with your local Motor Vehicle Bureau for
possible restrictions.
Danger!
Risk of loss of control and damage to the
vehicle as well as serious personal injury or
death.
The standard tires profile and rubber mixture
are optimized for wet and dry driving condi-
tions, and may not prove favorable for snow
conditions.
fTherefore install M+S tires before driving in such conditions. Before mounting snow tires, consult with
your Porsche dealer. He has the technical
information necessary to advise you on
wheel and tire compatibility.
Snow tires should have the same load capacity as
original equipment tires and should be mounted on
all four wheels.
Snow tires with studs should be run at moderate
speeds when new in order to give the studs time
to settle.
Danger!
Tires with badly worn treads and studs are
very dangerous and could cause accidents
resulting in serious personal injuries or
death.
fMake sure they are replaced immediately.
fDo not drive a vehicle equipped with snow tires
at prolonged high speed.
Snow tires do not have the same degree of
traction on dry, wet or snowfree roads as a
normal tire.
Furthermore, snow tires wear rapidly under
these conditions.
Comply with all state and local laws
governing snow tire and tread depth require-
ments.
