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.

Maintenance, Car Care
Fuel Economy Fuel economy will vary depending on where,
when and how you drive, optional equipment
installed, and the general condition of your
car.
A car tuned to specifications and correctly
maintained, will help you to achieve optimal
fuel economy.
fHave your vehicle tuned to specifications.
Air cleaner should be dirt free to allow proper
engine “breathing”.
Battery should be fully charged.
Wheels should be properly aligned.
Tires should be inflated at correct pressure.
fAlways monitor your fuel consumption.
fDrive smoothly, avoid abrupt changes in speed
as much as possible.
fAvoid jack rabbit starts and sudden stops.
fDo not drive longer than necessary in the lower
gears. Shifting into a higher gear early without
lugging the engine will help save fuel.
fProlonged “warm up” idling wastes gas. Start
the vehicle just before you are ready to drive.
Accelerate slowly and smoothly.
fSwitch off the engine if stationary for longer
periods. fAny additional weight carried in the vehicle
reduces fuel economy. Always keep cargo to a
minimum and remove all unnecessary items.
fOrganize your trips to take in several errands
in one trip.
fAll electrical accessories contribute to incre-
ased fuel consumption.
fOnly switch on the air conditioning when neces-
sary.
The EPA estimated miles per gallon (mpg) is
to be used for comparison purposes, actual
mileage may be different from the estimated
mpg, depending on your driving speed,
weather conditions and trip length. Your
actual highway mileage will probably be less
than the estimated mpg.
fPlease observe all local and national speed
limits.
Operating your Porsche in other
Countries Government regulations in the United States and
Canada require that automobiles meet specific
emission regulations and safety standards. There-
fore, cars built for the U.S. and Canada differ from
vehicles sold in other countries.
If you plan to take your Porsche outside the conti-
nental limits of the United States or Canada, there
is the possibility that
– unleaded fuel may not be available;
– unleaded fuel may have a considerably lower
octane rating. Excessive engine knock and
serious damage to both engine and catalytic
converters could result;
– service may be inadequate due to lack of
proper service facilities, tools or diagnostic
equipment;
– replacement parts may not be available or very
difficult to get.
Porsche cannot be responsible for the
mechanical damage that could result
because of inadequate fuel, service or parts
availability.
If you purchased your Porsche abroad and want to
bring it back home, be sure to find out about
shipping and forwarding requirements, as well as
current import and customs regulations.
