Power Steering
Warning!
Risk of accident.
When the engine is stopped (e.g. when on
tow) or the power steering has failed there is
no steering assistance.
Therefore, substantially more force will have
to be exerted in order to steer.
fExercise great care when being towed.
fHave the fault remedied at your nearest autho-rized Porsche dealer. Note
The flow noise heard at full steering lock is design-
related and does not indicate a defect in the stee-
ring system.
Checking hydraulic fluid fPlease observe the chapter “EXERCISE EXTRE-
ME CAUTION WHEN WORKING ON YOUR VE-
HICLE” on Page 184.
The hydraulic fluid reservoir is located in the engi-
ne compartment.
fOnly use hydraulic fluid authorized by Porsche.
fPlease observe the chapter “CAPACITIES” on
Page 286.
fCheck the fluid level with the engine stopped
and cold (approximately 68°F/20°C).
1. Open the engine compartment lid.
Please observe the chapter “OPENING ENGINE
COMPARTMENT LID” on Page 203.
2. Open the reservoir cap.
3. Wipe measuring rod.
Close lid and reopen. The fluid level should lie
in the area below the ”Cold“ marking.
Add hydraulic fluid if necessary.
4. Close cap carefully.
Close engine compartment lid.
Noticeable loss of fluid indicates leakage in the
system.
The cause should be remedied immediately at an
authorized Porsche dealer.

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 286.
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 286.
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.

Car Care Instructions fPlease observe the chapter “EXERCISE EXTRE-
ME CAUTION WHEN WORKING ON YOUR VE-
HICLE” on Page 184.
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.

210
Maintenance, Car Care
Washing The best method of protecting your car from the
damaging effects of the environment is frequent
washing and the application of a preservative. The
underside of your vehicle should also be tho-
roughly washed for cinders, salt or sanding at win-
ter’s end.
The longer salt, road dust and industrial dust,
dead insects, bird droppings or substances from
trees (resin, pollen) are allowed to remain on the
bodywork, the more serious is their harmful ef-
fect.
New cars should be washed carefully with plenty
of clear water to protect the new paint work. Dark
paint finishes show up the smallest of surface da-
mage (e.g., scratches) more readily than lighter
colors.
Dark colors are also more susceptible to scrat-
ching because of the composition of their pig-
ments and require particularly careful paint care.
fDo not wash your car in bright sunlight or while
the bodywork is still hot.
fWhen washing by hand, use abundant water, a
soft sponge or wash brush, and Porsche car
shampoo.
fBegin by spraying the body thoroughly with wa-
ter to rinse away loose dirt. fAfter washing, rinse the car with plenty of wa-
ter and then dry with a chamois leather.
Do not use the same chamois leather for
drying as you use for cleaning the windshield
and windows.
Warning!
Moisture which gets on to the brakes during
a car wash can reduce braking efficiency or
make the brakes pull unevenly which could
increase the danger of an accident, causing
serious personal injuries or death.
fAlways apply the brakes a few times after was-
hing the car to test braking efficiency and dry
the brake discs.
When doing this, take care not to hamper other
road users behind you (traffic conditions per-mitting).

211
Convertible top
fNever remove snow and ice using a sharp
edged object.
Incorrect care and treatment can damage the con-
vertible top and cause leaks. Any repair work can
be done by your authorized Porsche dealer.
Important note
No folding top is 100% leak proof.
Due to the constant changing of loads and strains
to which a car is subject to when driving on roads,
minor wind noise and seepage at joints between
the top, body and doors on convertible tops can-
not be completely sealed in certain areas. There-
fore small leaks are considered normal for these
models. In addition, your convertible top should
not be washed in a car wash. The top may experi-
ence damage by the brushes or may experience
leaks due to the high pressure water streams di-
rected in areas which would not encounter water
in normal driving conditions. Cleaning
Caution!
Risk of damage due to the cleaning jet of the
high-pressure cleaning equipment or hot wax
treatment.
fDo not clean the convertible top with high-
pressure cleaning equipment.
fDo not use the hot wax treatment.
Do not wash the convertible top each time the car
is washed.
It is usually sufficient to spray or wash it with clean
water.
fBrush dust off the convertible top in the direc-
tion of the weave using a soft brush.
fOnly if there is heavy dirt, wet the convertible
top with lukewarm water and the Porsche
Wash-Shampoo & convertible-top cleaner,
using a sponge or soft brush, and rub gently.
Rinse Wash-Shampoo & convertible-top clea-
ner thoroughly off the convertible top with
clean water.
fAfter washing it, treat the convertible-top cover
at least once a year with the special Porsche
convertible-top care product.
Do not allow the convertible-top care product
to come into contact with paint or windows. If
it does, remove immediately. fIf there is leakage in the convertible-top cover
or at its seams or folds, the special Porsche
convertible-top care product can be used.
fPlease note the information on the container.
fRemove bird droppings immediately since the
acid in them will make the rubber swell and the
convertible top will become leaky.
fOpen convertible top only when it is completely
dry, otherwise damp stains and scrub marks
may occur which cannot be removed.
fTry to remove spots from the convertible-top
cover by rubbing carefully with a soft rubber
sponge.

212
Maintenance, Car Care Automatic car washes
Optional add-on parts or parts which project
beyond the contours of the vehicle may be
damaged by design features (e.g. brushes) of au-
tomatic car washes.
The following parts are particularly suscep-
tible to damage:
– Convertible top (hot wax treatment cannot be
used, as the wax attacks the convertible top
material),
– Windshield wipers (always switch them off to
prevent them wiping unintentionally in intermit-
tent or sensor operation)
– External telephone antenna (always unscrew)
– Fixed rear spoiler or extended rear spoiler
– Wheels (the wider the rim and the lower the tire
height, the greater the risk of damage)
– High-gloss wheels (to prevent these from get-
ting scratched, do not clean with the wheel-
cleaning brushes of the car wash).
fPlease consult the operator before using auto-
matic car washes.
fWash and dry by hand all points not reached by
a car wash, such as door and lid seams or
door sills. Note
Automatic car washes spray water at odd angles
and high pressures, which are not seen in normal
driving. Therefore, water can sometimes find its
way into the passengers compartment during or
shortly after the car wash.
Door locks fTo prevent the door locks from freezing during
the cold season, the lock cylinders should be
covered during a wash.
fShould the locks freeze, use an ordinary de-
icer. In many cases, a well warmed key can
help.
Never use excessive force.

Maintenance, Car Care
213
Paint fNever rub a dusty car with a dry cloth since
dust particles are abrasive and could dull and
damage the surface finish.
The paintwork of your car is exposed to all types
of mechanical and chemical conditions, particular-
ly climatic ones such as bright sunlight, rain, frost
and snow. Ultraviolet light, rapid changes in tem-
perature, rain, snow, industrial dust and chemical
deposits constantly attack the paint which is only
able to withstand such exposure in the long term
if it is given regular care and attention.
fDo not apply silicone polishes to the winds-
hield, windows or convertible top.
fDo not treat matt-painted components with
preservatives or polishes as this will spoil the
matte effect. Preservation
The paint surface becomes dull over time due to
weathering. It is therefore necessary to preserve
the paint regularly.
This keeps the paint shiny and elastic. Dirt is
prevented from adhering to the paint surface and
industrial dust is prevented from penetrating the
paint.
Provided it is washed and treated with preserva-
tive regularly, the brand new finish of your vehicle
will be retained for years to come.
fSimply apply paint preservative after washing
the vehicle and polish it smooth.
Polishing
Do not resort to using Porsche polish until it beco-
mes evident that the normal preservatives no lon-
ger produce the desired finish.
Spots and stains
fRemove tar stains, grease, oil spots and dead
insects as soon as possible with Insect Remo-
ver. They can cause discoloration if allowed to
remain on the paintwork.
fWash the affected area immediately after trea-
ting it. Minor paint damage
fHave minor paint damage, such as scratches,
scores or chips caused by flying stones, re-
paired immediately by your authorized
Porsche dealer before corrosion sets in.
However, if there are already traces of corrosion,
they must first be removed carefully and tho-
roughly. Coat the area with a rust-proofing primer
and finish off with a top coat. The paint code and
color number are found on the data bank in the
Maintenance booklet.

214
Maintenance, Car Care
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 engi-
ne 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 dama-
ge. A full under-body wash should also be perfor-
med 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 po-
lish and could smear the windows and thus im-
pair 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 perfekt condition are vital
for a clear view.
fReplace the wiper blades twice per year (be-
fore and after the cold season) or whenever wi-
per 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 ne-
cessary 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.

Maintenance, Car Care
215
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. Stainless steel exhaust tailpipesStainless steel exhaust tailpipes can discolour 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.
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.
