Development philosophyPorsche 911 GT3 stands for a sports car with
exceptional performance, both on the road and on
the race track. This objective means that, in the
event of any compromise being required between
sportiness and comfort during the development
process, the tendency will be geared more
towards sportiness. This can result in the following
restrictions in comfort:
– Brake squeal when light pressure applied to
the pedal shortly before stopping.
– Rough engine operation in speed range around
3000 rpm.
– Cracking noise in area of front-axle coil
springs.
– Greater operating force for clutch and gear
shifting.
– Aerodynamic-related extremely low vehicle
position with restrictions in terms of ground
clearance.Sport tiresYour vehicle is equipped with special sport tires
(ultra high performance tires).
This type of tire is approved for use on public
highways and complies with all statutory require-
ments and safety criteria.The design of the tire is also geared towards use
on racing circuits (driver safety training courses,
sports driving schools, Club Sport events) and
provides distinct advantages here in terms of dry
grip and wear compared to conventional road
tires.
The major features are a reduced tread depth and
a special tread pattern and carcass.
Due to ultra high performance design and the
particular manufacturing process of these tires,
they must always be replaced in axle sets (2)
regardless of wear or mileage. Failure to do so
may have a negative affect on the handling charac-
teristics of the vehicle.
The design features of this sports tire result
in the following effects compared with other
summer tires when used under normal
driving conditions:
– Sport tires have a smaller tread depth, and
thus can reach their wear limit sooner.
As with all tires, the attainable mileage
depends on the individual driving style and the
conditions of use.
– Exercise caution when driving on wet roads,
paying special attention to hydroplaning situa-
tions (stagnant water, puddles, lane grooves).
Sport tires have a lower tread depth than
normal tires and you must therefore adapt
speed accordingly when driving on wet
surfaces.– The driver’s skill level must be commensurate
with the vehicle performance levels in the
upper range limits, due to increased safety
risks in the upper range limits.
fAt oudside temperatures below 45 °F (7 °C)
change to winter tires.
fNotify anyone using your car of these charac-
teristics and possible effects.
Danger!
Risk of accident through loss of road surface
contact, control over the vehicle and braking
ability, leading to serious personal injury or
death.
The reduced tire tread depth means that
there is an increased risk of hydroplaning on
wet roads.
fWhen driving on wet or mud-covered roads reduce speed significantly. Danger!
Risk of accident from worn tires.
Sport tires have a smaller tread depth, and
thus can reach their wear limit sooner.
It is important to check tire wear frequently
to avoid risk of serious personal injury or
death from worn tires.
fCheck tire wear frequently.

airbag deployment, you should always sit back
as far from the steering wheel as is practical,
while still maintaining full vehicle control.
fAdjust the inside and outside rear view mirrors.
fBuckle your safety belts.
fCheck operation of the foot and parking brake.
fCheck all warning and indicator lights with
ignition on and engine not running.
fStart engine and check all warning displays for
warning symbols.
fNever leave an idling car unattended.
fLock doors from inside, especially with
children in the car to prevent inadvertent
opening of doors from inside or outside.
Drive with doors locked.
On the road... fNever drive after you have consumed alcohol
or drugs.
fAlways have your safety belt fastened.
fAlways drive defensively.
Expect the unexpected.
fUse signals to indicate turns and lane changes.
fTurn on headlights at dusk or when the driving
conditions warrant it.
fAlways keep a safe distance from the vehicle in
front of you, depending on traffic, road and
weather conditions.
fReduce speed at night and during inclement
weather.
Driving in wet weather requires caution and
reduced speeds, particularly on roads with
standing water, as the handling characteristics
of the vehicle may be impaired due to hydropla-
ning of the tires.
fAlways observe speed limits and obey road
signs and traffic laws.
fWhen tired, get well off the road, stop and take
a rest. Turn the engine off. Do not sit in the
vehicle with engine idling.
Please see the chapter “ENGINE EXHAUST” on
Page 8.fWhen parked, always set the parking brake.
Move the gearshift lever to reverse or first
gear.
On hills also turn the front wheels toward the
curb.
fWhen emergency repairs become necessary,
move the vehicle well off the road. Turn on the
emergency flasher and use other warning
devices to alert other motorists. Do 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.
fMake it a habit to have the engine oil checked
after every refueling.

Engine Oil It is important to perform oil changes regularly in
accordance with the intervals specified in the
“Maintenance” booklet.Engine oil consumption It is normal for your engine to consume oil.
The rate of oil consumption depends on the quality
and viscosity of oil, the speed at which the engine
is operated, the climate, road conditions as well
as the amount of dilution and oxidation of the
lubricant.
If the vehicle is used for repeated short trips, and
consumes a normal amount of oil, the engine oil
measurement may not show any drop in the oil
level at all, even after 600 miles (1,000 km) or
more. This is because the oil is gradually
becoming diluted with fuel or moisture, making it
appear that the oil level has not changed.
The diluting ingredients evaporate out when the
vehicle is driven at high speeds, as on an
expressway, making it then appear that oil is
excessively consumed after driving at high
speeds.
If the conditions you drive your vehicle in are
dusty, humid, or hot, the frequency of the oil
change intervals should be greater. If the vehicle is driven at a high rate of speed,
climatic conditions are warm, and the load is high,
the oil should be checked more frequently, as
driving conditions will determine the rate of oil
consumption.
– The engine in your vehicle depends on oil to
lubricate and cool all of its moving parts.
Therefore, the engine oil should be checked
regularly and kept at the required level.
– Make it a habit to have the engine oil level
checked at every refueling.
– The oil pressure warning light is not an oil level
indicator.
The oil pressure warning light indicates serious
engine damage may be occuring when lit, if
engine rpm is above idle speed.

fRegularly check the oil level using the on-board
computer after the vehicle is refueled.
Please see the chapter “OIL DISPLAY AND
MEASUREMENT OF THE ENGINE OIL LEVEL”
on Page 143.
The difference between the minimum and
maximum marks on the segment display is
approx. 1.1 quarts (1.0 liters).
Each segment of the display corresponds to
approx. 0.32 quart (0.3 liter).
Topping off engine oilPorsche recommends .1) Generally, you can find details on the
manufacturer approvals on the oil containers or as
a notice displayed by the retailer.
The current approval status is also available from
your authorized Porsche dealer.2) SAE viscosity class – Example: SAE 0W - 40
Specification 0W = Viscosity specification for low
temperatures (winter).

Refueling Fuel tank capacity is listed under “Capacities”.
fPlease see the chapter “CAPACITIES” on
Page 239.
Porsche does not recommend the use of fuel
additives.
Fuel is highly flammable and harmful to
health.1.Important: Stop the engine and switch off the
ignition.
2. Slowly unscrew the tank cap.
Hang the tank cap's plastic strap on the hook
on the inside wall of the filler flap.
3. Insert fuel-hose nozzle fully into the filler neck
with the handle of the fuel-hose nozzle facing
down.
4. Do not add further fuel once the correctly
operated automatic fuel-hose nozzle has
switched off.
Fuel could spray or could run over in warm
temperatures.
5. Replace the tank cap immediately after
refueling and turn it until you hear it and feel it
engage.
If you lose the tank cap, you must replace it
only with an original part to reduce the possi-
bility of a fire in the event of a collision.
Caution!
Risk of damage. Body decals may bleach if
they come into contact with fuel.
fClean up any spilt fuel immediately.
Fuel Recommendations Your Porsche is equipped with catalytic conver-
ters and must use UNLEADED FUEL ONLY.
Your engine is designed to provide optimum
performance and fuel economy using unleaded
premium fuel with an octane rating of 98 RON
(93
CLC or AKI). Porsche therefore recom-
mends the use of these fuels in your vehicle.
Porsche also recognizes that these fuels may not
always be available. Be assured that your vehicle
will operate properly on unleaded premium fuels
with octane numbers of at least
95 RON
(90 CLC or AKI), since the engine’s “Electronic
Octane™ knock control” will adapt the ignition
timing, if necessary.
It is important to observe the regular service inter-
vals, and particularly the oil change intervals,
specified in the “Maintenance” booklet.
The use of UNLEADED FUEL ONLY is critically
important to the life of the catalytic conver-
ters. Deposits from leaded fuels will ruin the
converters and make it ineffective as an
emission control device.
Cars with catalytic converters have a smaller fuel
tank opening, and gas station pumps have smaller
nozzles. This will prevent accidental pumping of
leaded fuel into cars with catalytic converters.

mance, but can lead to premature engine wear.
Regular filter replacement is part of the routine
maintenance service.
fIn dusty conditions, check the filter element
more frequently and replace if necessary.Combination Filter The fresh air passing through the combination
filter into the passenger compartment is virtually
free of dust, pollen, and unpleasant odors.
fIf the outside air is polluted by exhaust fumes,
press the recirculating-air button.
A dirty filter can be the cause of reduced air flow:
fHave filter replaced by your authorized
Porsche dealer.
Regular filter replacement is part of the routine
