Car Care Instructions fPlease observe the chapter “EXERCISE EXTRE-
ME CAUTION WHEN WORKING ON YOUR VE-
HICLE” on Page 198.
Regular and correct care helps to maintain
the value of your car and is also a
precondition 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
pleased 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 chil-
dren.
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, fend-
ers, 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 brak-
ing efficiency.
fTest the brakes after each vehicle washing.

Maintenance, Car Care
219
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 thorough-
ly washed for cinders, salt or sanding at winter’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
damage (e.g., scratches) more readily than lighter
colors.
Dark colors are also more susceptible to scratch-
ing because of the composition of their pigments
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 dry-
ing 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
washing 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).

Maintenance, Car Care 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, us-
ing a sponge or soft brush, and rub gently.
Rinse Wash-Shampoo & convertible-top clean-
er 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.

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
susceptible 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 antennas (always unscrew)
– Roof Transport System (always remove com-
pletely)
–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 lock fTo prevent the door lock from freezing during
the cold season, the lock cylinder should be
covered during a wash.
fShould the lock freeze, use an ordinary de-icer.
In many cases, a well warmed key can help.
Never use excessive force.

222
Maintenance, Car Care
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 windshield
or windows.
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 pre-
vented from adhering to the paint surface and in-
dustrial dust is prevented from penetrating the
paint.
Provided it is washed and treated with preserva-
tive regularly, the brand new finish of your car will
be retained for years to come.
fApply paint preservative after the car wash and
polish it dry to obtain a bright finish. Polishing
Do not resort to using Porsche polish until it be-
comes evident that the normal preservatives no
longer produce the desired finish.
Spots and stains
fRemove tar stains, grease, oil spots and dead
insects as soon as possible with Insect Remov-
er. They can cause discoloration if allowed to
remain on the paintwork.
fWash the affected area immediately after treat-
ing 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 thorough-
ly. 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 Mainte-
nance booklet.
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.

Maintenance, Car Care
223
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 Porsche insect re-
mover.
Note
Door windows feature a water-repellent (hydro-
phobic) 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 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 un-
dercoating 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.
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 any deposits or dirt and grease. Once it
has dried, the new undercoating compound
forms a tough protective coating which pro-
vides efficient rust-proofing of the floor panels
and components.
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.

Maintenance, Car Care
Light alloy wheels fPlease observe the chapter “WASHING” on
Page 219.
Warning!
Danger of accident if cleaning agents (e.g.
wheel cleaning agents) come into contact
with the brake discs. The resulting film on the
brake discs can impair braking perform-
ance.
fMake sure that no cleaning agent comes into
contact with the brake discs.
fIf cleaning agent has come into contact with
the brake discs, thoroughly clean the brake
discs with a strong jet of water.
fPaying attention to any road users behind you,
dry the brake discs by applying the brakes at short intervals.Pitting may occur if metallic particles which cause
contact corrosion (e.g. brass or copper in brake
dust) are allowed to remain on the aluminum for
too long.
fIf possible, wash the wheels with a sponge or
wash brush about every two weeks. In areas
where salt is spread on winter roads or there is
a lot of airborne industrial dust, it is best to
clean the wheels weekly.
The Porsche Light Alloy Wheel Cleaner
(ph-value 9.5) can be used for this pur-
pose.
If the ph-value of the detergent is incor-
rect, the protective coating on the wheels
will be destroyed.
Polishes which dissolve oxides, such as those
frequently used for other metals, or abrasive
tools or agents are unsuitable because they
break down the oxide film of the protective
coating and will cause discoloration of the
wheel.
fEvery three months, after cleaning, coat the
wheels with a car wax or non-corrosive grease
(vaseline).
Using a clean cloth thoroughly rub the grease
into the surface.
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 prod-
uct.
In order to prevent damage to the anti-
friction coating, the inner door seals, the
convertible 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. 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.
