Environmentally friendly vehiclesModern environmental technology ensures compli-
ance with all emission laws applicable worldwide.
It has 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 observe the chapter “FUEL ECONOMY”
on Page 249.
Recycling –
for a Porsche, this is virtually an
academic questionMore than two-thirds of all Porsches ever built are
still running.
But, just in case recycling is ever necessary,
we take the following precautionary
measures:
– Utilisation-friendly design.
– Identification of materials.
– Use of recyclable materials.
– Reusable components designed for simple
removal.
Emission control is built inInnovative engine technology combines high
engine performance and environmental compati-
bility.
The engine diagnosis system electronically
monitors the components and systems that affect
exhaust gases.
This continuous monitoring and fault storage
enables swift, reliable diagnosis and fault detec-
tion.
Faults are indicated to the driver by the “Emission
control” warning light and display.
fPlease observe the chapter “EMISSION CONT-
ROL” on Page 76.

6Setting and operating vehicle
components when driving
Warning!
There is a danger of accident if you set or
operate the on-board computer, radio, navi-
gation system, telephone or other equipment
when driving.
This could distract you from the traffic and
cause you to lose control of the vehicle.
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.
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.

8Fuel 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.

Dear Porsche OwnerA lot has gone into the manufacture of your
Porsche, including advanced engineering, rigid
quality control and demanding inspections. These
engineering and safety features will be enhanced
by you...the safe driver...– who knows his car and all controls,
– who maintains the vehicle properly,
– who uses driving skills wisely and always
drives within her/his own capabilities and the
level of familiarity with the vehicle.
You will find helpful hints in this manual on how to
perform most of the checks listed on the following
pages. If in doubt, have these checks performed
by your authorized Porsche dealer.
Before driving off...Check the following items firstfTurn the engine off before you attempt any
checks or repairs on the vehicle.
fBe sure the tires are inflated correctly.
Check tires for damage and tire wear.
fSee that wheel bolts are properly tightened
and not loose or missing.
fCheck engine oil level, add if necessary. Make
it a habit to have engine oil checked with every
fuel filling.
fCheck all fluid levels such as windshield wash-
er and brake fluid levels.
fBe sure the vehicle battery is well charged and
cranks the engine properly.
fCheck all doors and lids for proper operation
and latch them properly.
fCheck and if necessary replace worn or
cracked wiper blades.
fSee that all windows are clear and unobstruct-
ed.
fCheck air intake slots and area between en-
gine compartment lid and windshield are free
of snow and ice, so the heater and the wind-
shield wipers work properly.fIf a child will be riding in the vehicle, check
child seat/child seat restraint system to ensure
that restraints are properly adjusted.
fCheck all exterior and interior lights for opera-
tion and that the lenses are clean.
fCheck the headlights for proper aim, and if
necessary, have them adjusted.
fCheck under the vehicle for leaks.
fBe sure all luggage is stowed securely.
Emergency equipmentIt is good practice to carry emergency equipment
in your vehicle.
Some of the items you should have are: window
scraper, snow brush, container or bag of sand or
salt, emergency light, small shovel, first-aid kit,
etc.

In the driver's seat...fCheck operation of the horn.
fPosition seat for easy reach of foot pedals and
controls.To reduce the possibility of injury from
the airbag deployment, you should always sit
back as far from the steering wheel as is prac-
tical, 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 igni-
tion 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 chil-
dren 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 re-
duced speeds, particularly on roads with
standing water, as the handling characteristics
of the vehicle may be impaired due to hydro-
planing 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 ve-
hicle with engine idling.
Please observe the chapter “ENGINE EX-
HAUST” on Page 6.fWhen parked, always set the parking brake.
Move the Tiptronic selector lever to “P“.
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 de-
vices to alert other motorists. Do not park or
operate the vehicle in areas where the hot ex-
haust system may come in contact with dry
grass, brush, fuel spill or other flammable ma-
terial.
fMake it a habit to have the engine oil checked
with every fuel filling.

Break in hints for the first
2,000 miles (3,000 kilometers)The following tips will be helpful in obtaining opti-
mum performance from your new Porsche.
Despite the most modern, high-precision manufac-
turing methods, it cannot be completely avoided
that the moving parts have to wear in with each
other. This wearing-in occurs mainly in the first
2,000 miles (3,000 km).Therefore:fPreferably take longer trips.
fAvoid frequent cold starts with short-distance
driving whenever possible.
fAvoid full throttle starts and abrupt stops.
fDo not exceed maximum engine speed of
4,200 rpm (revolutions per minute).
fDo not run a cold engine at high rpm either in
Neutral or in gear.
fDo not let the engine labor, especially when
driving uphill. Shift to the next lower gear in
time (use the most favorable rpm range).
fNever lug the engine in high gear at low
speeds. This rule applies at all times, not just
during the break-in period.fDo not participate in motor racing events,
sports driving schools, etc. during the first
2,000 miles/3,000 kilometers.
There may be a slight stiffness in the steering or
other controls during the break-in period which will
gradually disappear.
Break in brake padsNew brake pads and 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 com-
pensated for by pressing the brake pedal harder.
This also applies whenever the brake pads and
brake discs are replaced.New tiresNew tires do not have maximum traction. They
tend to be slippery.
fBreak in new tires by driving at moderate
speeds during the first 60 to 120 miles/100
to 200 km. Longer braking distances must be
anticipated.
Engine oil consumptionDuring the break-in period oil consumption may be
higher than normal.
As always, the rate of oil consumption depends on
the quality and viscosity of oil, the speed at which
the engine is operated, the climate and road con-
ditions, as well as the amount of dilution and oxi-
dation of the lubricant.
fMake a habit of checking engine oil with every
fuel filling, add if necessary.
fPlease observe the chapter “ENGINE DATA” on
Page 346.
