maintenance PORSCHE 911 GT3 2010 5.G Owners Manual

2Dear Owner, We would like to thank you for your purchase of a
Porsche Sports car.
Judging by the car you have chosen, you are a
motorist of a special breed, and you are probably
no novice when it comes to automobiles.
Remember however, as with any vehicle, you
should take time to familiarize yourself with your
Porsche and its performance characteristics.
Always drive within your own unique capabilities as
a driver and your level of experience with your
Porsche. Ensure that anyone else driving your
Porsche does the same. To prevent or minimize
injury, always use your safety belts. Never
consume alcohol or drugs before or during the
operation of your vehicle.
This Owner’s Manual contains a host of useful
information. Please take the time to read this
manual before you drive your new Porsche.
Become familiar with the operation of your
Porsche car for maximum safety and operating
pleasure. The better you know your Porsche, the
more pleasure you will experience driving your
new car.
Always keep your Owner’s Manual in the car, and
give it to the new owner if you ever sell your
Porsche. A separate Maintenance Booklet explains how
you can keep your Porsche in top driving condition
by having it serviced regularly.
A separate Warranty and Customer Informa-
tion Booklet contains detailed information about
the warranties covering your Porsche.
For U.S. only:
If you believe that your vehicle has a fault which
could cause a crash, injury or death, you should
immediately inform the National Highway Traffic
Safety Administration (NHTSA) in addition to
notifying Porsche Cars North America, Inc.
(Porsche Cars N.A.).
If NHTSA receives similar complaints, it may open
an investigation, and if it finds that a safety
problem exists in a group of vehicles, it may order
a recall and remedy campaign. However, NHTSA
cannot become involved in individual problems
between you and your dealer, or
Porsche Cars N.A.
To contact NHTSA, you may call the Vehicle Safety
Hotline toll-free at 1-888-327-4236 (TTY: 1-800-
424-9153); go to http://www.safercar.gov; or
write to: Administrator,
NHTSA, 400 Seventh
Street, SW., Washington, DC 20590.
You can also obtain other information about motor
vehicle safety from http://www.savercar.gov.
Your car has thousands of parts and components
which have been designed and manufactured in
accordance with Porsche’s high standards of
engineering quality and safety.
Warning!
Any alteration or misuse of the vehicle can
lead to accidents and severe or fatal
personal injuries.
Any alteration of the vehicle may negate or
interfere with those safety features built into
the vehicle. Modifications may be carried out
on your vehicle only if approved by Porsche.
Your Porsche is intended to be used in a safe
manner obeying the local laws and in the
light of driving conditions faced by you, and
in accordance with the instructions provided
in this Owner’s Manual.
fDo not misuse your Porsche by ignoring those
laws and driving conditions, or by ignoring the instructions in this 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 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
Safety Belts
Warning!
Always make sure your and your passenger’s
safety belts are properly fastened while
seated in the vehicle.
Failure to follow safety belt warnings may
result in serious personal injury or death.
fFor your and your passenger’s protection, use
safety belts at all times while the vehicle is in
motion.
fUse appropriate child restraint systems for all
small children.
Proper wearing of safety belts
fS a f e t y b e l t s m u s t b e p o s i t i o n e d o n t h e b o d y a s
to restrain the upper body and lap from sliding
forward. Improperly positioned safety belts
can cause serious personal injury or death in
case of an accident.
fThe shoulder belt should always rest on your
upper body. The shoulder belt should never be
worn behind your back or under your arm.
fFor maximum effectiveness, the lap belt
should be worn low across the hips.
fPregnant women should position the belt as
low as possible across the pelvis. Make sure it
is not pressing against the abdomen. fBelts should not be worn twisted.
fDo not wear belts over rigid or breakable
objects in or on your clothing, such as eye
glasses, pens, keys, etc. as these may cause
injury.
fSeveral layers of heavy clothing may interfere
with proper positioning of belts.
fBelts must not rub against sharp objects or
damage may occur to the belt.
fTwo occupants should never share the same
belt at the same time.
Care and maintenance
fKeep belt buckles free of any obstruction that
may prevent a secure locking.
fBelts that have been subjected to excessive
stretch forces in an accident must be
inspected or replaced to ensure their conti-
nued effectiveness in restraining you.
The same applies to belt tensioner systems
which have been triggered.
In addition, the anchor points of the belts
should be checked.
fIf safety belts do not work properly, see your
authorized Porsche dealer immediately.
fI f t h e b e l t s s h o w d a m a g e t o w e b b i n g , b i n d i n g s ,
buckles or retractors, they should be replaced
to ensure safe operation.
fDo not modify or disassemble the safety belts
in your vehicle. fThe belts must be kept clean or the retractors
may not work properly.
Please see the chapter “CAR CARE INSTRUC-
TIONS” on Page 174.
fNever bleach or dye safety belts.
fDo not allow safety belts to retract until they
are completely dry after cleaning or this may
cause damage to the belt.
Belt tensioner Depending on the force of an impact, fastened
safety belts are tightened in an accident.
The belt tensioners are triggered in:
– Front, side and rear impacts of sufficient
severity.
Note
The belt-tensioner system can be triggered only
once; the system must be replaced afterward.
If there is a fault in the belt-tensioner system, the
airbag warning light lights up.
Work may be performed on the belt-tensioner
system only by an authorized Porsche dealer.
Smoke is released when the belt tensioners are
triggered. This does not indicate a fire in the
vehicle.

Note
The key switch for switching off the passenger’s
airbag in combination with the LATCH attachment
bracket are not installed at the factory. They can
be retrofitted.
fPlease see your authorized Porsche dealer.
Faults are indicated by a warning light in the instru-
ment panel and a message on the on-board
computer.
fPlease see the chapter “WARNINGS ON THE
INSTRUMENT PANEL AND THE ON-BOARD
COMPUTER” on Page 148.
fIn the following cases you should immedi-
ately consult an authorized Porsche
dealer in order to assure the airbag
system is functioning properly:
– If the warning light does not light up when the
ignition key is inserted or
– If the warning light does not go out once the
engine is running or
– If the warning light appears while driving.
Airbag maintenanceIn order to ensure long-term functioning, the
airbag system must be inspected by an authorized
Porsche dealer at the intervals recommended in
your Maintenance Booklet.
Important information
If you sell your Porsche, notify the purchaser that
the vehicle is equipped with airbags, and refer
them to the chapter, “Airbag Systems“, in the
Owner's Manual (safety and disposal rules).
Further information on the airbag system can be
found on stickers attached to the sun visors.

Operation, Safety
Brake booster The brake booster assists braking only when
the engine is running.
When the car is moving while the engine is not
running, or if the brake booster is defective, more
pressure on the brake pedal is required to bring
the car to a stop.
If this happens, ABS and PSM will also not
operate.
Moisture or road salt on brakes affects braking.
Brakes will dry after a few cautious brake applica-
tions.
Warning!
Risk of an accident, resulting in serious
personal injury or death.
Driving through water may reduce the
traction.
Moisture on brakes from road water, car
wash, or coating of road salt may affect
braking efficiency.
fCautiously apply brakes to test brakes after exposure to road water, etc.
Brake wear Your car has excellent brakes, but they are still
subject to wear. The rate at which they wear
depends on how the brakes are used.
fHave the brake system inspected at the
intervals recommended in your Maintenance
Booklet.
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 stay on when the engine is
running or come on while driving, the brake pads
are worn excessively.
fDo not continue to operate the vehicle.
Have your authorized Porsche dealer inspect
or replace the brake pads.
Brake pads Wear on the brake pads and brake discs depends
to a great extent on the driving style and the condi-
tions of use and therefore cannot be expressed in
actual miles on the road.
The high-performance brake system is designed
for optimal braking effect at all speeds and tempe-
ratures.
Certain speeds, braking forces and ambient
conditions (such as temperature and humidity)
therefore might cause “brake noises”. This also
applies after completion of the breaking-in period
required for the new brake components.
New brake pads or linings
New brake pads and brake discs have to be
“broken in”, and therefore only attain optimal
friction when the car has covered several hundred
miles or km.
The slightly reduced braking ability must be
compensated for by pressing the brake pedal
harder. This also applies whenever the brake pads
and brake discs are replaced.

further rain sensor functions can be selected via
the PCM.
fPlease see the chapter “Individual Memory” in
the separate PCM Owner’s Manual.
Changing the sensitivity of the rain sensor
Sensitivity can be set with switch A in 4 stages:
fAdjust switch A upwards –
high sensitivity.
The setting is confirmed by one wipe of the
windshield.
fAdjust switch A downwards –
low sensitivity.Maintenance note
fPeriodically clean the wiper blades with a
window cleaner, especially after the vehicle
has been washed in a car wash. We recom-
mend Porsche window cleaner. If they are very
dirty (e.g. with insect remains), they can be
cleaned with a sponge or cloth.
If the wiper blades rub or squeak, this may be as
a result of the following:
– If the vehicle is washed in an automatic car
wash, wax residues may be adhering to the
windshield. These wax residues can only be
removed by using a window cleaner concen-
trate.
fPlease see the chapter “WASHER FLUID” on
Page 170.
fPlease contact your authorized Porsche dealer
for further information.
– The wiper blades may be damaged or worn.
fReplace damaged wiper blades as soon as
possible.

Exercise Extreme Caution when
Working on your Vehicle
Danger!
Ignoring the following instructions may
cause serious personal injury or death.
fThe engine compartment of any motor vehicle
is a potentially hazardous area. If you are not
fully familiar with proper repair procedures, do
not attempt the adjustments described on the
following pages.
This caution also applies to the entire vehicle.
fO n l y w o r k o n y o u r v e h i c l e o u t d o o r s o r i n a w e l l
ventilated area.
fEnsure that there are no open flames in the
area of your vehicle at any time when fuel
fumes might be present. Be especially
cautious of such devices such as hot water
heaters which ignite a flame intermittently.
fBefore working on any part in the engine
compartment, turn the engine off and let it cool
down sufficiently. Hot engine compartment
components can burn skin on contact.
fBe alert and cautious around engine at all
times while the engine is running.
If work has to be performed with the engine
running, always set the parking brake, and
make sure the shift lever is in neutral position.fIn particular, be very careful to ensure that
items of clothing (ties, shirt, sleeves etc.),
jewelry, long hair, hand or fingers cannot get
caught in the engine-compartment blower, fan,
belts or other moving parts.
The radiator and radiator fans are in the front
of the car.
The engine-compartment blower is mounted
on the engine-compartment lid.
The engine-compartment blower can start or
continue running as a function of temperature,
even with the engine switched off.
Carry out work in these areas only with the
engine off, the ignition switched off, and
exercise extreme caution.
fYour Porsche is equipped with an electronic
ignition system. When the ignition is on, high
voltage is present in all wires connected with
the ignition system; therefore, exercise
extreme caution when working on any part of
the engine while the ignition is on or the engine
is running.
fAlways support your car with safety stands if it
is necessary to work under the car.
fWhen working under the car without safety
stands but with the wheels on the ground,
make sure the car is on level ground, the
wheels are blocked, and that the engine
cannot be started.
Remove the ignition key. fDo not smoke or allow an open flame around
the battery or fuel.
Keep a fire extinguisher close at hand.
fIncomplete or improper servicing may cause
problems in the operation o f t h e c a r. I f i n d o u b t
about any servicing, have it done by your
authorized Porsche dealer.
Improper maintenance during the warranty
period may affect your Porsche warranty
coverage.
fSupplies of fluids, e.g. engine oil, brake fluid or
coolant, are hazardous to your health.
Keep these fluids out of children’s reach and
dispose of them in accordance with the appro-
priate regulations.
fSome countries require additional tools and
special spare parts to be carried in your
vehicle.
Please make enquiries before driving abroad.
Power measurementsPower measurements on dynamometers are not
approved by Porsche.

Maintenance, Car Care
Coolant LevelfPlease see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 157.
The cooling system is filled at the factory with a
permanent coolant.
It provides year-round protection from corrosion
and freezing down to –31 °F/–35 °C
.
fOnly use antifreeze authorized by Porsche.
Checking coolant level The expansion tank with its filler orifice is in the
left-hand side of the engine compartment.
fCheck the coolant level regularly through the
transparent expansion tank.
When the engine is cold and the car is level the
fluid level must lie between the “MIN” and “MAX”
markings. Topping off coolant
Warning!
Danger of serious personal injury or death
from scalding. Coolant is hazardous to your
health, and may be fatal if swallowed.
fDo not open the cap of the expansion tank
while the engine is hot.
fAllow the engine to cool down before opening
the cap and protect your hands, arms and face
from any possible escape of hot coolant.
fKeep coolant out of children’s reach.
fAlso, keep coolant away from your pets.
They can be attracted to it should there be a
spill, or to used coolant left in an open
container. Coolant can be deadly to pets if consumed.1. Switch engine off and let it cool.
Please see the chapter “COOLING SYSTEM” on
Page 112.
2. Cover the expansion tank cap with a thick rag.
Open cap slowly and carefully and allow
overpressure to escape.
Then unscrew cap completely.
3. Only add a mixture of antifreeze and water in
equal parts, and do not exceed the “MAX”
mark.
Antifreeze in coolant:
50% gives protection down to –31 °F/–35 °C
60% gives protection down to –58 °F/–50 °C
4. Screw cap firmly on.
If in an emergency pure water has been added, the
mix ratio must be corrected at an authorized
Porsche dealer.
Marked loss of coolant indicates leakage in the
cooling system.
The cause should immediately be remedied at an
authorized Porsche dealer.
