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

Brake system warning light
You can check the functionality of the brake
system warning light by switching the ignition to
the “On” position and verifying that the warning
light illuminates.
If the warning lights in the instrument panel and on-
board computer go on while driving, the brake
fluid level may be too low, or (if the brake pedal
travel has increased) one of the two brake circuits
may have failed.
A greater braking pressure will be required,
stopping distances will be longer and the braking
behavior will change, particularly in curves.
With correctly adjusted brakes, and a correctly
working brake system, the pedal travel to the
point of brake actuation should be 1-3/16 in. to
1-9/16 in. or 30 to 40 mm.
Whenever the brake pedal travel exceeds this
distance, have the brake system checked.
Brake pedal
Warning!
Risk of an accident, resulting in serious
personal injury or death.
Any obstruction of the brake pedal could
increase the stopping distance.
fAlways check the movement of the brake pedal
before driving and make sure that it is not
obstructed by a floor mat or any other object.
fSecure the floor mat to prevent it from sliding
into positions that could interfere with the safe
operation of your vehicle.
Your Porsche dealer will be glad to offer you nonskid floor mats of the correct size.
Note
In case one of the two brake circuits fails, incre-
ased pedal travel is required to bring your vehicle
to a full stop.
Warning!
To avoid overheating and premature wear of
the brakes:
fBefore descending a steep grade, reduce
speed and shift the transmission into a lower
gear to control speed.
fDo not “ride the brakes” by resting your foot on
the pedal when not intending to apply brake
pressure.
fDo not hold the pedal down too long or too
often.
This could cause the brakes to get hot and not function properly.

AntennafAlways unscrew the external antenna before
using an automatic car-wash.
Car Telephone and
Aftermarket Alarms Important legal and safety information
regarding the use of cellular telephones
Some states may prohibit the use of cellular
telephones while driving a vehicle. Check the laws
and regulations on the use of cellular telephones
in the areas where you drive.
Danger!
Risk of an accident.
Serious personal injury or death can result in
the event of an accident.
Looking away from the road or turning your
attention away from your driving can cause
an accident and serious or fatal injury.
When using your cellular telephone, you should
always:
fGive full attention to your driving - pull off the
road and park before making or answering a
call if traffic conditions so require; and
fKeep both hands on the steering wheel - use
hands-free operation (if available) - pull off the
road and park before using a hand-held telephone. It is essential to observe the telephone
manufacturer's instructions before operating
the telephone.
Any portable telephone or radio transmitter which
is used in a Porsche must be properly installed in
accordance with the technical requirements of
Porsche.
The transmission power must not exceed
10 W.
The devices must possess a type approval for
your vehicle and have an “e” symbol.
If you should require equipment with transmission
power values greater than 10 W, please consult
your authorized Porsche dealer for this purpose.
The dealer is familiar with the technical require-
ments for installing devices of this kind.
The antennas for all radios and telephones with a
transmitting antenna must be externally mounted.
The improper installation of radios or telephones
or use of a radio or telephone with a transmitting
antenna inside the car may cause the warning
lights to come on.
Improper installation of such equipment can
create a discharged battery or excessive current
draw from added equipment.

Manual Transmission, ClutchThe positions of the gears are shown on the shift
diagram on the gearshift lever.
Warning!
Risk of accident, resulting in serious
personal injury or death.
fDo not obstruct the pedal travel with floor mats
or other objects.
Nonskid floor mats of the correct size are
available at your authorized Porsche dealer.To avoid damage to the clutch and transmis-
sion:
fAlways depress the clutch pedal fully when
changing gears. Make sure that the gearshift
lever is completely engaged.
fOnly shift into reverse when the car has come
to a complete stop.
fWhen shifting gears, always ensure that the
clutch pedal is fully depressed and the gear
has fully engaged.
fSelect reverse only when vehicle is stationary.
fSelect an appropriately low gear on upward
and downward slopes.
This will ensure optimum use of engine power
and engine braking.
When reverse gear is selected and the ignition is
on, the backup lights are illuminated.
Permitted engine speedfYou should change into a higher gear before
the needle reaches the red mark on the tacho-
meter, or ease off the accelerator.
If the red zone is reached during acceleration, fuel
feed is interrupted.
Caution!
Risk of engine damage (overrevving) when
shifting down to a lower gear.
fTake care not to exceed the maximum permitted engine speed when shifting down.
In addition to the red zone on the tachometer
scale, the upshift arrow also prompts you to
initiate the gear shift in good time.
