Maintenance, Car Care
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.
Caution!
Risk of damage if the wiper arm accidentally
falls back on to the window.
f Always hold the wiper arm securely when re-
placing the wiper blade.
Risk of damage if wiper blades that are fro-
zen in place are loosened improperly.
f Thaw the wiper blades before loosening them.
Maintenance note
f Periodically clean the wiper blades with win-
dow cleaner, especially after the vehicle has
been washed in a car wash.
We recommend the Porsche window cleaner. If
they are very dirty (e.g. with insect remains),
they can be cleaned with a sponge or cloth. If the wiper blades rub or squeak, this can be as a
result of the following:
– If the vehicle is washed in an automatic car
wash, wax residues may adhere to the wind-
shield. These wax residues can be removed
only by using window cleaner concentrate.
– The wiper blades may be damaged or worn.
– Replace damaged or worn wiper blades as soon as possible.
– Please see the chapter “WASHER FLUID” on Page 200.
f Please contact your authorized Porsche dealer
for further information.
Changing wiper bladesfPlease read the separate instructions for fitting
wiper blades as supplied by the manufacturer.
f We recommend that you get your authorized
Porsche dealer to replace the wiper blades.
Caution!
Risk of damage.
If the wiper blades are not changed properly,
they can come loose when the car is moving.
f Check that the wiper blades are seated
securely. The wiper blades must engage properly in the wiper arm.

Car Care Instructions fPlease see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 186.
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 we ll as damage to your
vehicle. f
Keep cleaning agents out of reach from chil-
dren.
f Observe all caution labels.
f Always read directions on the container before
using any product. These directions may con-
tain information necessary to avoid personal
injury.
f Do 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.
f Do 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.
f Test the brakes after each vehicle washing.
Decorative film
Caution!
Risk of damage due to separation of the
decorative film when cleaning your vehicle
with high-pressure cleaning equipment or
steam cleaners.
f Do not use high-pressure cleaning equipment or steam cleaners for cl eaning decorative film.
High-pressure cleaning units, steam
cleaners
Warning!
High-pressure cleaning units or steam clean-
ers can damage the following components:
–tires,
– logos, emblems,
– painted surfaces,
– alternator,
– ParkAssist sensors.
f Please observe the operating instructions from
the unit manufacturer.
f When cleaning with a flat-jet nozzle or the like,
maintain a minimum distance of 20 inches (50
cm).
f Never use high-pressure cleaning units or
steam cleaners with a ro und-jet nozzle. A high-
pressure cleaning unit or steam cleaners with
round nozzle will damage your vehicle.
f The tires are particularly susceptible to dam-
age.
f Do not point the cleaning jet directly at any of the aforementioned components.

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 thorough-
ly washed for cinders, salt or sanding at winter’s
end.
The longer salt, road du st and industrial dust,
dead insects, bird droppi ngs 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 compos ition of their pigments
and require particularly careful paint care.
f Do not wash your car in bright sunlight or while
the bodywork is still hot.
f When washing by hand, use abundant water, a
soft sponge or wash brush, and Porsche car
shampoo.
f Begin by spraying the body thoroughly with wa-
ter to rinse away loose dirt. f
After 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.
f After washing the car, test the brakes and
steering and briefly brake the discs dry.
When doing this, take care not to hamper other
road users behind you (traffic conditions permitting).
Automatic car washes
f Please see the chapter “WIPER BLADES” on
Page 202.
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:
– Windshield wipers (alw
ays switch them off to
prevent them wiping unintentionally in intermit-
tent or sensor operation)
– External antennas (always unscrew)
– 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).
f Please consult the operator before using auto-
matic car washes.
f Wash 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.

Maintenance, Car Care
205
Door lock fTo prevent the door lock from freezing during
the cold season, the lo ck cylinder should be
covered during a wash.
f Should the lock freeze, use an ordinary de-icer.
In many cases, a well warmed key can help.
Never use excessive force.Paint To protect the paint on yo ur vehicle in the best
possible way against mechanical and chemical
damage, you should
– preserve it regularly,
– polish it if necessary,
– remove spots and stains, and
– repair damaged paintwork.
f Do not apply care products containing silicone
to the convertible top and windows.
General information
f Never rub a dusty vehicle with a dry cloth,
because the grains of dirt will damage the
paintwork.
f Do not treat matt-painted components with
preservatives or polish es, otherwise the matt
effect will be lost. Preservation
The paint surface becomes dull over time due
to weathering.
f
Preserve paint regularly.
f Apply paint preservative after washing the
vehicle and polish it smooth to preserve the
paintwork.
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.
Polishing
Do not resort to using Porsche polish until it be-
comes evident that the no rmal preservatives no
longer produce the desired finish.
Spots and stains
f Remove 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.
f Wash the affected area immediately after treat-
ing it. Minor paint damage
f
Have 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.
f Please see the chapter “VEHICLE DATA BANK”
on Page 264.
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.

206
Maintenance, Car Care
Caution!
Risk of damage to the alternator.
f Do not point the cleaning jet directly at the al-ternator, or cover the alternator.
Effective rust-proofing is particularly important
during the cold weather season. If the vehicle is
driven frequently in areas where salt has been
spread on the roads, the engine compartment
should be cleaned thoroughly and subsequently
sealed after the cold weather season to prevent
salt from causing any lasting damage.
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 th e windows. These deposits
are augmented by impurities in the air which en-
ters the car through the fresh air vents.
f Clean all windows regularly, inside and outside,
with Porsche window cleaner.
f If 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.
f Remove 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.
f Consult an authorized Porsche dealer.
Wiper blades Wiper blades that are in perfect condition are vital
for a clear view.
fPlease see the chapter “WIPER BLADES” on

are damaged.
f Periodically 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.

for further information.
The wiper blades may be damaged:
f Replace damaged wiper blades as soon as
possible.
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 interv als – 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 recommen d 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
207
Warning!
Danger of fire resulting in serious personal
injury or death.
f Do 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.
f Before applying fresh underseal, carefully
remove any deposits of dirt and grease. Once
it has dried, the new undercoating compound
forms a tough protective coating which
provides efficient rust-proofing of the floor
panels and components.
f Always 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 seas on. If your car is driv-
en frequently in areas wh ere 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.
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.Light alloy wheels f Please see the chapter “WASHING” on
Page 204.
Warning!
Danger of accident resulting in serious per-
sonal injury or death if cleaning agents (e.g.
wheel cleaning agents) come into contact
with the brake discs.
The resulting film on the brake discs can im-
pair braking performance.
f Make sure that no clea ning agent comes into
contact with the brake discs.
f If cleaning agent has come into contact with
the brake discs, thoroughly clean the brake
discs with a strong jet of water.
f Paying attention to any road users behind you,
dry the brake discs by applying the brakes at short intervals. Metal particles (such as brass or copper in brake
dust) must not remain to
o long on alloy wheels.
Contact corrosion can cause pitting.
Cleaners with an oxide-removing effect or the
wrong pH value, as are commonly used for other
metals, as well as mechanical tools and products,
will damage the oxide layer and are therefore
unsuitable.
f Use only cleaners for alloy wheels
(pH value 9.5). Products with the wrong
pH value can destroy the protective layer
on the wheels.
We recommend Porsche cleaner for alloy rims.
f If possible, wash the wheels every two weeks
with a sponge or washing brush. If the wheels
are exposed to road salt, grit or industrial dust,
weekly cleaning is necessary.

Maintenance, Car Care
Door, lid and window seals
Caution!
The lubricant coating on the inner door
seals, convertible top and hardtop seals
may be damaged by unsui table cleaning and
care agents.
f Do not use any chemical cleaning agents
or solvents.
fDo not use any preservative agents.
f Wash dirt (e.g. abrasion, dust, road salt and
grit) from all seals regularly using warm
soapy water.
f If there is a risk of frost, protect the outer door
seals and lid seals against freezing into place
with a suitable care product.Headlights, lights, interior and exterior
plastic parts, adhesive filmsUse only clean water and a little dishwashing
detergent to clean light lenses, plastic headlight
lenses, plastic parts, adhesive films 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.
An interior window cleane r can also be used to
clean plastic surfaces (always read the cleaning
instructions on the container). We recommend
Porsche interior window cleaner. f
Gently wipe the surface without applying too
much pressure.
f Do not clean when dry.
f Never use other chemical cleaners or
solvents.
f Rinse cleaned surfaces with clear water.
Leather Characteristics and special features
The natural surface markings of leather, e.g.
creases, healed scars, insect sting marks, struc-
tural differences and slight variations in shade and
grain add to the attractiveness of the natural leath-
er product.
Observe the following care instructions:
Caution!
The leather will be damaged by the use of
unsuitable cleaning and care agents and by
incorrect treatment.
f Do not use caustic cleaners or hard
cleaning aids.
f Perforated leather must under no circumstances get wet on its reverse side.
f Clean all types of leather regularly to remove
fine dust using a soft, damp, white woollen
cloth or a commercially available
microfibre cloth. f
Remove heavy contamination with a leather
cleaner.
Always read the instructions for use given on
the containers.
We recommend Porsche leather cleaner.
f Treat cleaned leather only with a leather
care product.
We recommend the Porsche leather
care product.
Cleaning airbags covers
Danger!
There is a danger of serious personal injury
or death if the airbag system is impaired by
improper cleaning work.
f Do not make any modifications whatsoever on
individual components such as the padded
covers of the steering wheel, passenger side
instrument panel, the front seats and the door
linings.
f Let your authorized Porsche dealer clean these components.

Maintenance, Car Care
209
Fabric, upholstery, carpets and
floor-mats fUse only a vacuum clea ner or a medium stiff
brush.
f Remove stains and spots with Porsche stain
remover.
To protect carpets, the Porsche range of accesso-
ries includes mats of the correct size and with the
appropriate fastening.
Warning!
Risk of an accident resulting in serious per-
sonal injury or death.
f Always check the movement of the pedals be-
fore driving and make sure that they are not ob-
structed by a floor-mat or any other object.
f Secure the floor-mat to prevent it from sliding
into positions that could interfere with the safe
operation of your vehicle - do not install them
loosely in the vehicle.
Your Porsche dealer will be glad to offer you nonskid floor-mats of the correct size.
Cleaning fabric liningsfFabric linings on pillar s, convertible top liner
and sun blinds, etc. must be cleaned only
using suitable cleaning agents or a suitable dry
foam and a soft brush.Alcantara f Do not use a leather care product to clean
Alcantara.
For regular care it is sufficient to clean the cover
with a soft brush.
Heavy abrasion or rubbing when cleaning causes
a lasting change in the surface.
Cleaning when lightly soiled
f Wet a soft cloth with water or a neutral soap
solution and wipe off the dirt.
Cleaning when heavily soiled
f Wet a soft cloth with lukewarm water or
thinned white spirit and dab the dirt from the
outside in.
Cleaning safety belts f Use mild detergent to clean soiled belts.
f When drying, avoid direct sunlight.
f Only use suitable cleaning agents.
f Do not tint or bleach the belts.
The belt fabric could be weakened, thus affec-
ting safety.
