Maintenance, Car Care
Air Filter The air filter is on the left-hand side of the engine
compartment.
A dirty air filter not only reduces engine perform-
ance, but can lead to premature engine wear.
Regular filter replacement is part of the routine
maintenance service.
fIn dusty conditions, check the filter element
more frequently and replace if necessary. Combination filterThe fresh air passing through the combination
filter into the passenger compartment is virtually
free of dust, pollen, and unpleasant odors.
fIf the outside air is polluted by exhaust fumes,
press the circulating-air button.
A dirty filter can be the cause of reduced air
throughput:
fHave the filter replaced by an authorized
Porsche dealer.
Regular filter replacement is part of servicing.
Automatic Transmission Fluid The torque converter and the transmission are lu-
bricated with Automatic Transmission Fluid (ATF).
The final drive requires transmission oil.
fPlease observe the chapter “CAPACITIES” on
Page 271.
Do not tow the car or run the engine without ATF
in the transmission. The automatic transmission
may be damaged by even a tiny speck of dirt, only
a clean funnel or spout must be used when adding
AT F.
The ATF and transmission oil has to be checked
and changed at the intervals listed in your Mainte-
nance Schedule.
We recommend that you have the ATF and trans-
mission oil changed at your Porsche dealer, who
has the required lubricants and the necessary fill-
ing equipment.
If you suspect an oil leak in the transmission, have
your authorized Porsche dealer check it out imme-
diately.
Manual Transmission Oil The transmission oil has to be checked and
changed at the intervals listed in your Maintenance
Schedule.
fPlease observe the chapter “CAPACITIES” on
Page 271.
We recommend that you have the transmission oil
changed at your Porsche dealer, who has the re-
quired lubricants and the necessary filling equip-
ment.
If you suspect an oil leak in the transmission, have
your authorized Porsche dealer check it out imme-
diately.

Cleaning and preserving engine
compartment The engine compartment and the surface of the
engine are treated with a corrosion-inhibitor at the
factory.
If degreasing solvents are used to clean the en-
gine compartment or the engine is washed down,
the process almost invariably removes the corro-
sion-inhibiting coating. It is then absolutely neces-
sary to have a durable preservative applied to all
surfaces, body seams, joints and assemblies in
the engine compartment. This also applies when
corrosion-inhibitor parts are replaced.
Caution!
Risk of damage to the alternator.
fDo not point the cleaning jet directly at the al-ternator, or cover the alternator.
Effective corrosion-proofing is particularly impor-
tant during the cold weather season. If your car is
driven frequently in areas where salt has been
spread on the roads, the whole engine compart-
ment should be cleaned thoroughly after the win-
ter to prevent salt from causing any lasting dam-
age. A full under-body wash should also be per-
formed at the same time.
Windows The road dust which settles on the windshield and
windows contains particles of tire rubber and oil
residue. The interior trim and upholstery release
particles, particularly in strong sunlight, which col-
lect on the insides of the windows. These deposits
are augmented by impurities in the air which en-
ters the car through the fresh air vents.
fClean all windows regularly, inside and outside,
with Porsche window cleaner.
fIf you use a chamois leather for the windows,
do not use it for paintwork as it will otherwise
pick up a certain amount of preservative or
polish and could smear the windows and thus
impair vision.
fRemove dead insects with the Porsche insect
remover.
Note
Door windows feature a water-repellent (hydropho-
bic) coating which prevents soiling of the windows.
This coating is subject to natural wear and can be
renewed.
fConsult an authorized Porsche dealer.
Wiper blades Wiper blades that are in perfect condition are vital
for a clear view.
fReplace the wiper blades twice per year (be-
fore and after the cold season) or whenever
wiper performance deteriorates.
fPeriodically clean the wiper blades with
Porsche window cleaner, especially after the
vehicle has been washed in a car wash.
If they are very dirty (e.g. with insect remains),
they can be cleaned with a sponge or cloth. Undercoating The underside of your car is durably protected
against chemical and mechanical influences.
As it is not possible to exclude the risk of damage
to this protective coating in day to day driving, it
is advisable to have the underside of the car in-
spected at certain intervals - preferably before the
start of winter and again in spring - and the under-
coating restored as necessary.
Your authorized Porsche dealer is familiar with the
bodyseal treatment procedures and has the nec-
essary equipment for applying factory approved
materials. We recommend that you entrust them
with such work and inspections.
Unlike conventional spray oils, undercoating and
rust-proofing compounds based on bitumen or
wax do not attack the sound-proofing materials ap-
plied at the factory.

200
Maintenance, Car Care
Warning!
Danger of fire and serious personal injuries.
fDo not apply additional undercoating or rust-
proofing on or near the exhaust manifold, ex-
haust pipes, catalytic converters or heat
shields. During driving the substance used for undercoating could overheat and ignite.
fBefore applying fresh underseal, carefully re-
move deposits or dirt and grease. Once it has
dried, the new undercoating compound forms
a tough protective coating which provides effi-
cient rust-proofing of the floor panels and com-
ponents.
fAlways apply a fresh coating of suitable pre-
servative to unprotected areas after cleaning
the underside of the body, the transmission,
the engine or carrying out repairs to under-
body, engine or transmission components.
Effective rust-proofing is particularly important
during the cold weather season. If your car is driv-
en frequently in areas where salt has been spread
on the roads, the whole engine compartment
should be cleaned thoroughly after the winter to
prevent salt from causing any lasting damage. A
full under-body wash should also be performed at
the same time.
Door, lid and window seals fWash dirt (e.g. abrasion, dust, road salts) from
all seals regularly using warm soapy water. Do
not use any chemical cleaning agents or sol-
vents.
When there is a frost hazard, the outer door seals
and the front and rear lid seals can be protected
against freezing into place by a suitable care prod-
uct.
In order to prevent damage to the anti-fric-
tion coating, the inner door seals must not be
treated with care products. Stainless steel exhaust tailpipesStainless steel exhaust tailpipes can discolor due
to soiling, strong heat, and combustion residues.
The original polish can be achieved again using
commercially available metal polishing paste or
metal polish.
Headlights, lights, interior and exterior
plastic parts fUse only clean water and a little dishwashing
detergent to clean light lenses, plastic head-
light lenses, plastic parts and surfaces.
Do not clean when dry.
Use a soft sponge or a soft, lint-free cloth. Gen-
tly wipe the surface without applying too much
pressure.
The Porsche inside window cleaner is also suit-
able for cleaning plastic surfaces. Follow the
cleaning instructions on the container.
Never use other chemical cleaners or
solvents.
fRinse cleaned surfaces with clear water.

Storing your Porsche If you intend to store your Porsche for a prolonged
period, please consult your authorized Porsche
dealer. The staff will be glad to advise you on the
most suitable and necessary methods.
fClean your vehicle thoroughly inside and out-
side.
Clean the engine compartment.
The under carriage and chassis components
should be free of dirt and salt deposits.
fFill up the fuel tank.
fChange the oil and oil filter, and run the engine
for several minutes.
fIncrease the tire pressure to 58 psi (4 bar).
It is not recommended to lift the vehicle, due to
the possibility of corrosion on shock absorber
piston shafts.
The vehicle should be moved slightly, approxi-
mately every four weeks, to prevent flat spot
on the tires. Climate control
The air conditioning system should be in good
working condition and fully charged.
Windshield/Headlight washer
fCheck and correct antifreeze/cleaning solution
level as necessary.
Electrical system
fRemove the battery from the vehicle and store
it in a cool dry place, not on a cement floor.
When the battery is disconnected, the
alarm system is deactivated.
fRecharge the battery every 3 months. If the
battery remains in the vehicle with the cables
connected, it is necessary to check, remove
and recharge the battery every 2-3 weeks.
Do not fast charge the battery.
fPlease observe the chapter “BATTERY” on
Page 235. Vehicle interior
The interior must be dry, especially in the area of
the floor carpets. The use of drying agents (Silica-
Gel) is recommended in vehicles with leather inte-
rior and in areas with high humidity. The recom-
mended amount is 3 fabric bags of 1.1 lbs. (500
grams) each placed on the floor carpets.
Windows, doors, lids and top must be closed. The
air vents should be opened.

Practical Tips, Emergency Service
Exercise Extreme Caution when
Working on your Vehicle
Danger!
Ignoring the following instructions may
cause 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 heat-
ers 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.), jew-
elry, 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 volt-
age 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.
Jacks are not suitable for this kind of work.
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 close at hand.
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 in your vehi-
cle.
Please make enquiries before driving abroad.
Working in the engine compartmentHave the necessary work in the engine compart-
ment done by a qualified specialist workshop.
We recommend that you use your authorized
Porsche dealer for carrying out this work.
