4Fuel Quality 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 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 Octane™ knock control” will adapt the ignition timing, if necessary. Fuels containing alcohol and ether Some 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, that you 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 MMT Some 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.

Environmentally friendly vehicles Modern 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.
– Please observe the chapter “FUEL ECONOMY”
on Page 184.
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 in Innovative engine technology combines high en-
gine performance and environmental compatibili-
ty.
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.

Dear Porsche Owner A 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 first fTurn 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 front
lid and windshield are free of snow and ice, so
the heater and the windshield 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 equipment It 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 air-
bag 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 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.
fPlease observe the chapter “ENGINE EX-
HAUST” on Page 8.fWhen parked, always set the parking brake.
Move the Tiptronic selector lever to ”P“ or 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 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.
Danger!
Danger of fire in engine compartment due to
burning cigars or cigarettes. Serious perso-
nal injury or death could result from fire in
the engine compartment.
fDo not throw any lit cigars or cigarettes out of
the vehicle.
They can be blown into the air inlets by the air
flow and cause a fire in the engine compart-
ment.
fPlease observe the chapter “ASHTRAY” on Page 138.

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,
gear-shifting or other controls during the break-in
period which will gradually disappear.
Break in brake pads and break discsNew 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 tires New 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 an-
ticipated.
Engine oil and fuel consumption During the break-in period oil and fuel consump-
tion 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.

Controls, Instruments
Operation of the ABS system A wheel speed sensor is mounted to each of the
four wheels. If wheel lock-up of either of the front
wheels or the rear wheels is sensed during brak-
ing, the brake pressure is adjusted automatically
until the wheel no longer slips. The brake pressure
is regulated for each front wheel individually and
for both of the rear wheels together.
On a road surface which is slippery on only one
side, the rear wheel which is braking on the slip-
pery surface determines the brake pressure which
will be applied equally to both rear wheels. This en-
sures that directional stability is maintained. How-
ever, if braking forces approach the wheel lock-up
point for all wheels (panic braking) the ABS system
will intervene to provide a rapid rhythmic braking.
The proper operation of ABS is perceived by the
driver as a pulsating brake pedal in conjunction
with audible noise and perhaps some vibration.
fIf you experience these sensations while driv-
ing or a road surface with questionable trac-
tion, reduce vehicle speed appropriate for the
prevailing road conditions.
The functional readiness of all the main electrical
components of the ABS is checked by an electron-
ic monitoring system both before and while you
drive. When the ignition is switched on the ABS warning
light will light up while the system is electronically
interrogated and goes out when the engine is
started if the check is not yet complete.
If the ABS warning lamp fails to go out, this indi-
cates that ABS has been deactivated due to a
fault. If the warning lights in the instrument panel
and on-board computer light up while you are driv-
ing, this indicates that a fault has occurred. In both
cases, normal braking, as in vehicles without ABS,
is still retained.
The ABS system should, however, be examined at
an authorized Porsche dealer immediately to pre-
vent the occurrence of further faults.
fIf the ABS system becomes inoperative, take
your vehicle to your authorized Porsche dealer
immediately.
Warning!
The control unit of the ABS brake system is
set for standard tire size. If non-standard
tires are installed, the control unit may mis-
interpret the speed of the vehicle, because of
the variant data it receives from the sensors
on the axles.
fUse only tire makes and types tested by Porsche.
