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 perfor-
mance, 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 odours.
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 266.
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 fil-
ling 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 chan-
ged at the intervals listed in your Maintenance
Schedule.
fPlease observe the chapter “CAPACITIES” on
Page 266.
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.

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 preser-
vative 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 du-
ring the cold weather season. If your car is driven
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, roof, 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 pro-
duct.
In order to prevent damage to the anti-fric-
tion coating, the inner door seals, the con-
vertible top seals and hardtop seals must not
be treated with care products.
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.
Gently wipe the surface without applying too
much pressure.
The Porsche inside window cleaner is also sui-
table for cleaning plastic surfaces. Follow the
cleaning instructions on the container.
Never use other chemical cleaners or
solvents.
fRinse cleaned surfaces with clear water.

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.
