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 mo-
torist 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. Al-
ways 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 in-
jury, 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 in-
formation. Please take the time to read this manu-
al before you drive your new Porsche. Become fa-
miliar with the operation of your Porsche car for
maximum safety and operating pleasure. The bet-
ter 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 prob-
lem exists in a group of vehicles, it may order a re-
call and remedy campaign. However, NHTSA can-
not become involved in individual problems be-
tween you and your dealer, or Porsche Cars N.A..
To contact NHTSA, you may either call the Auto
Safety Hotline toll-free at 1-(800)-424-9393
(or
366-0123 in Washington, D.C. area) or write
to: NHTSA, U.S. Department of Transportation,
Washington, D.C. 20590. You can also obtain oth-
er information about motor vehicle safety from the
Hotline. Your car has thousands of parts and components
which have been designed and manufactured in
accordance with Porsche’s high standards of engi-
neering quality and safety.
Any alteration of the vehicle may negate or
interfere with those safety features built into
the vehicle.
Your Porsche is intended to be used in a safe man-
ner obeying the local laws and in the light of driv-
ing conditions faced by you, and in accordance
with the instructions provided in this Owner’s Man-
ual.
Do not misuse your Porsche by ignoring
those laws and driving conditions, or by
ignoring the instructions in this manual.
Any alteration or misuse of the vehicle can
lead to accidents and severe or fatal
personal injuries.
The fitting of racing tires (e.g. slicks) for sporting
events is not approved by Porsche. Very high cor-
nering speeds can be achieved with racing tires.
However, the resulting transverse acceleration
values would jeopardize the adequate supply of oil
to the engine.
Porsche therefore will not accept any warranty or
accept any liability for damage occurring as a re-
sult of non-compliance with this provision.

3
Regularly check your vehicle for signs of
damage.
Damaged or missing aerodynamic compo-
nents such as spoilers or underside panels
affect the driving behavior and therefore
must be replaced immediately.
Your car may have all or some of the components
described in this manual.
Should you have difficulty understanding any of
the explanations of features or equipment installed
in your vehicle, contact your authorized Porsche
dealer. He/She will be glad to assist you. Also
check with your dealer on other available options
or equipment.
Throughout this booklet, left is designated as the
driver’s side of the vehicle, and right as the pas-
senger’s side of the vehicle.
Text, illustrations and specifications in this manual
are based on the information available at the time
of printing.
It has always been Porsche’s policy to continuous-
ly improve its products. Porsche, therefore, re-
serves the right to make changes in design and
specification, and to make additions or
improvements in its product without incurring any
obligation to install them on products previously
manufactured.
We wish you many miles of safe and pleasurable
driving in your Porsche.
Important
For your own protection and longer service life of
your car, please follow all operating instructions
and special warnings. These special warnings use
the safety alert symbol, followed by the words
Danger, Warning and Caution. These special
warnings contain important messages regarding
your safety and/or the potential for damage to
your Porsche. Ignoring them could result in seri-
ous mechanical failure or even physical injury.
fDo not alter your Porsche. Any alteration could
create dangerous conditions or defeat safety
engineering features built into your car.
fDo not misuse your Porsche. Use it safely, and
consistently with the law, according to the driv-
ing conditions, and the instructions in this man-
ual.
Alteration or misuse of your Porsche could
cause accidents and severe or fatal personal
injuries.

4Fuel QualityYour 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 recommends 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 Oktane™ knock control“ will adapt the ignition timing, if necessary.Fuels containing alcohol and etherSome areas of the U.S. require oxygenated fuels during certain portions of the year.
Oxygenated fuels are fuels which contain alcohols (such as methanol or ethanol) or ether (such as MTBE).
Under normal conditions, the amount of these compounds in the fuel will not affect driveability.
You may use oxygenated fuels in your Porsche, provided the octane requirements for your vehicle are met.
We recommend, however, to change to a different fuel or station if any of the following problems occur with your vehicle:
– Deterioration of driveability and performance.
– Substantially reduced fuel economy.
– Vapor lock and non-start problems, especially at high altitude or at high temperature.
– Engine malfunction or stalling.Fuels containing MMTSome North American fuels contain an octane enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT).
If such fuels are used, your emission control system performance may be negatively affected.
The check engine warning lights on your instrument panel may turn on.
If this occurs, Porsche recommends you stop using fuels containing MMT.

6Porsche and the Environment Environmental guidelinesWe develop and produce exclusive sports cars
with advanced environmental and safety technolo-
gy and a great ability to fascinate.
Our environmental policy is based on the
following principles:
– The maximum possible use of environmental
and safety technology that is economically jus-
tifiable.
– Economical usage of energy and resources.
– Involvement of our business partners and con-
tractors in our efforts to protect the environ-
ment.
– Open dialogue with all social groups. California Proposition 65 Warning
Warning!
Engine exhaust, some of its constituents, and cer-
tain vehicle components contain or emit chemi-
cals known to the State of California to cause can-
cer and birth defects or other reproductive harm.
In addition, certain fluids contained in vehicles and
certain products of component wear contain or
emit chemicals known to the State of Ca lifornia to
cause cancer and birth defects or other reproduc-
tive harm.
ProductionWhether in production or repair, Porsche always
relies on environmentally friendly technology.
An example of this is the water-based paint used
in our painting installations.
Water-base paints and new painting methods re-
duce solvent emissions by 70 per cent.
The water used in the painting installation is re-cir-
culated. Waste water leaves the Porsche factory
only after being appropriately treated.
A waste-management system has been introduced
to reduce the amount of waste while simultaneous-
ly increasing the recycling rate.

Environmentally friendly vehiclesModern environmental technology ensures compli-
ance with all emission laws applicable worldwide.
These have the following advantages:
– Rapid operational readiness of the catalytic
converters ensures low emissions, even in
short-trip operation.
– Reliable operation and good emission control
over a long useful life.
fPlease refer to the chapter “FUEL ECONOMY”
on page 187.
Recycling – for a Porsche, this is virtually
an academic question More than two-thirds of all Porsches ever built are
still running.
Just in case recycling is ever necessary, we
take the following precautionary measures:
– Identification of all materials.
– Use of recyclable materials.
– Reusable components designed for simple
removal.
– These reasons result in a further increase in
the recycling rate which is currently 80 per
cent.
Emission control is built inInnovative engine technology combines high en-
gine performance and environmental compati-
bility.
The engine diagnosis system electronically moni-
tors the components and systems that affect ex-
haust gases.
This continuous monitoring and fault storage ena-
bles swift, reliable diagnosis and fault detection.
Any fault messages are indicated to the driver by
the ”Check Engine“ warning light and the on-board
computer.
fPlease refer to the chapter “WARNINGS ON
THE INSTRUMENT PANEL AND THE ON-
BOARD COMPUTER” on page 105.

8Porsche Ceramic Composite Brake
(PCCB)The high-performance brake system is designed
for optimal braking effect at all speeds and
temperatures.
Certain speeds, braking forces and ambient
conditions (such as temperature and humidity)
therefore might cause brake noises.
Wear on the different components and braking
system, such as brake pads and brake discs,
depends to a great extent on the individual driving
style and the conditions of use and therefore
cannot be expressed in actual miles on the road.
The values communicated by Porsche are based
on normal operation adapted to traffic. Wear
increases considerably when the vehicle is driven
on race tracks or through an aggressive driving
style.
fPlease consult an authorized Porsche dealer
about the current guidelines in effect before
such use of your vehicle.
Setting and operating vehicle
components when driving
Warning!
There is a danger of accident if you set or op-
erate the on-board computer, radio, naviga-
tion system, telephone or other equipment
when driving.
This could distract you from the traffic and
cause you to lose control of the vehicle re-
sulting in serious personal injury or death.
fOperate the components while driving only if
the traffic situation allows you to do so safely.
fCarry out any complicated operating or setting procedures only with the vehicle stationary.
Portable Fuel Containers
Danger!
Portable fuel containers, full or partially
empty, may leak, causing an explosion, or
result in fire in case of an accident.
fNever carry additional fuel in portable contain-ers in your vehicle.

9
Engine Exhaust
Danger!
Engine exhaust is dangerous if inhaled.
Engine exhaust fumes have many compo-
nents 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 en-
closed, unventilated area.
It is not recommended to sit in your car for pro-
longed periods with the engine on and the car not moving.
Ground ClearancePlease bear in mind the limited ground clearance
of your car on uneven surfaces, when parking
(curbs), on ramps, lifting platforms, towing etc.
