Maintenance, Car Care
Changing the brake fluid Brake fluid absorbs moisture from the air over ti-
me. This accumulation of water lowers the boiling
point and, under certain operating con ditions,
can affect the braking action.
Therefore have the brake fluid changed in accor-
dance with the change intervals stated in the bro-
chure “Maintenance”. The brake-fluid warning lights in the instrument pa-
nel and on-board computer indicate:
– brake-fluid level too low,
– in conjunction with large pedal travel, braking-
circuit failure.
If the warning lights should light up while
driving:
fStop immediately in a suitable place.
fDo not continue driving.
Please have the fault remedied at your nearest
authorized Porsche dealer.

Car Care Instructions fPlease observe the chapter “EXERCISE EXTRE-
ME CAUTION WHEN WORKING ON YOUR VE-
HICLE” on Page 168.
Regular and correct care helps to maintain
the value of your car and is also a precondi-
tion for the New Vehicle Warranty and the
Anti Corrosion Warranty.
Your authorized Porsche dealer has specially
developed car-care products from the
Porsche program available either singly or
as complete car-care sets. They will be ple-
ased to help you select suitable products.
Whether you use Porsche products or other
commercially available cleaning agents first
make sure of their correct application.
A Porsche that is well-cared for can look like new
for years. It all depends on the amount of care the
owner is willing to give the car.
Warning!
Risk of serious personal injury or damage to
the vehicle or property.
Cleaning agents may be hazardous to your
health.
Most chemical cleaners are concentrates
which require dilution. High concentrations
might cause problems ranging from irritation
to serious injury as well as damage to your
vehicle.
fKeep cleaning agents out of reach from child-
ren.
fObserve all caution labels.
fAlways read directions on the container before
using any product. These directions may con-
tain information necessary to avoid personal
injury.
fDo not use fuel, kerosene, naphtha, nail polish
remover or other volatile cleaning fluids. They
may be toxic, flammable or hazardous in other
ways. Only use spot removing fluids in a well
vented area.
fDo not clean the underside of chassis, fen-
ders, wheel covers, etc., without protecting
your hands and arms as you may cut yourself on sharp-edged metal parts. Moisture and road salt on brakes may affect bra-
king efficiency.
fTest the brakes after each vehicle washing.

Practical Tips, Emergency Service
Exercise Extreme Caution when
Working on your Vehicle
Danger!
Ignoring the following instructions may cau-
se serious personal injury or death.
fThe engine compartment of any motor vehicle
is a potentially hazardous area. If you are not
fully familiar with proper repair procedures, do
not attempt the adjustments described on the
following pages.
This caution applies to the entire vehicle.
fO n l y w o r k o n y o u r v e h i c l e o u t d o o r s o r i n a w e l l
ventilated area.
fEnsure that there are no open flames in the
area of your vehicle at any time when fuel
fumes might be present. Be especially cau-
tious of such devices such as hot water hea-
ters which ignite a flame intermittently.
fBefore working on any part in the engine com-
partment, turn the engine off and let it cool
down sufficiently. Hot engine compartment
components can burn skin on contact.
fBe alert and cautious around engine at all
times while the engine is running.
If work has to be performed with the engine
running, always set the parking brake, and
make sure the shift lever is in neutral or the se-
lector lever is in position P.fIn particular, be very careful to ensure that
items of clothing (ties, shirt, sleeves etc.), je-
welry, long hair, hand or fingers cannot get
caught in the engine-compartment blower, fan,
belts or other moving parts.
The radiator and radiator fans are in the front
of the car.
The fans can start or continue running as a
function of temperature, even with the engine
switched off.
Carry out work in these areas only with the en-
gine off and exercise extreme caution.
fYour Porsche is equipped with an electronic ig-
nition system. When the ignition is on, high vol-
tage is present in all wires connected with the
ignition system; therefore, exercise extreme
caution when working on any part of the engine
while the ignition is on or the engine is running.
fAlways support your car with safety stands if it
is necessary to work under the car. The jack
supplied with the car is not adequate for this
purpose.
fWhen working under the car without safety
stands but with the wheels on the ground,
make sure the car is on level ground, the
wheels are blocked, and that the engine can-
not be started.
Remove the ignition key.fDo not smoke or allow an open flame around
the battery or fuel.
Keep a fire extinguisher in close reach.
fIncomplete or improper servicing may cause
problems in the operation of the car. If in doubt
about any servicing, have it done by your au-
thorized Porsche dealer.
Improper maintenance during the warranty pe-
riod may affect your Porsche warranty cover-
age.
fSupplies of fluids, e.g. engine oil, brake fluid or
coolant, are hazardous to your health.
Keep these fluids out of children’s reach and
dispose of them in accordance with the appro-
priate regulations.
fSome countries require additional tools and
special spare parts to be carried.
Please make enquiries before driving abroad.

Practical Tips, Emergency Service

Tire care fAvoid damaging tires and wheel rims.
fIf you must drive over a curb or other obstacle,
drive slowly and at an obtuse angle.
fCheck tires for uneven wear and damage
before driving off.
fRemove imbedded material.
fReplace worn or damaged tires immediately.
fKeep oil, fuel, brake fluid, etc. away from tires.
fReplace missing valve stem caps.
fKeep tires inflated correctly.
fWash tires when washing the vehicle.
Also clean inner side of wheels.
fDo not use abrasive cleaners when washing
the wheels.
fCheck wheel rims for corrosion.
fRemove road salt, if driving in winter.
Tire damage, puncture fCheck tires for imbedded material, cuts, punc-
tures, cracks and bulges (side wall) before driv-
ing off.
In case of tire damage, where it is uncertain wheth-
er there is a break in the ply with all its conse-
quences or tire damage caused by thermal or me-
chanical overloading due to loss of pressure or
any other prior damage, we recommend that the
tire be replaced for safety reasons.
If one faulty tire is replaced it should be noted that
the difference in tread depth on one axle must not
exceed 30 %.
Handling inconsistencies may result.
fPerform a visual inspection if necessary.
Danger!
Risk of serious personal injury or death.
Driving the vehicle with low tire pressure
increases risk of a tire failure and resulting
loss of control. Furthermore, low tire pres-
sure increases rate of wear of the affected
tires.
fCheck tires – including sidewalls – regularly for
foreign bodies, nicks, cuts, cracks and bulges.
fAfter driving off road, examine tires for signs
of damage such as cuts, tears, bulges or for-
eign objects stuck in the tread. Replace a dam-
aged tire if necessary.
fCross curb edges slowly and at right angles if
possible.
Avoid driving over steep or sharp curbs.
fIn cases of doubt, have the wheel (particularly
the inner side) checked by an authorized Porsche dealer.

Fuel tankRefill volume approx. 16.9 U.S. gallons/64 liters, including approx. 2.6 U.S.gallons/10 liters reserve.
Fuel 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.
