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.

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.

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.
A special mention must be made here of natural
leather.
For natural leather, carefully selected hides of the
highest quality are used. It is not covered com-
pletely with dye on production.
“Nature’s signature” is therefore easily recogniza-
ble.
This fine material is distinguished by an outstand-
ing seating comfort, special suppleness and a typ-
ical patina. Leather care and treatment
fClean all types of leather regularly to remove
fine dust using a soft, damp, white woollen
cloth or a commercially available microfibre
cloth.
fRemove heavy contamination with Porsche
leather cleaner.
Please always follow the instructions for use
given on the containers.
Caustic cleaners and hard cleaning objects
must not be used.
Perforated leather must under no circum-
stances get wet on its reverse side.
Once cleaned, leather (particularly the heavily
stressed leather seats) must be treated only with
Porsche leather care liquid.
Fabric, upholstery, carpets and
floor-mats fUse only a vacuum cleaner or a medium stiff
brush.
fRemove stains and spots with Porsche stain
remover.
The Porsche range of accessories includes non-
skid floor-mats to protect the carpets in summer
and winter.
Warning!
Risk of an accident.
fAlways 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.
fSecure 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.

226
Maintenance, Car Care
Alcantara fDo 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
fWet a soft cloth with water or a neutral soap
solution and wipe off the dirt.
Cleaning when heavily soiled
fWet a soft cloth with lukewarm water or
thinned white spirit and dab the dirt from the
outside in. Safety belts If it becomes necessary to clean the belts, you
can use any mild washing agent.
Allow the belts to dry prior to retracting, but avoid
direct sunlight.
fOnly use suitable cleaners.
If unsuitable cleaners are used or any attempt
is made to dye or bleach the belts, the web-
bing may be weakened and thus constitute a
safety risk.
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 258.
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 and lids 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 also 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 position
or the selector lever 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 engine-compartment blower is mounted
on the engine-compartment lid.
The engine-compartment blower 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, the ignition switched 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.
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
cannot be started.
Remove the ignition key.fDo not smoke or allow an open flame around
the battery or fuel.
Keep a fire extinguisher in close reach.
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.
Please make enquiries before driving abroad.

Tires/Wheels The original equipment tires and wheel rims on
your Porsche comply with all applicable Federal
Motor Vehicle Safety Standards.
For your safety remember the following:
– Wheel rims and wheel bolts are matched to fit
your Porsche.
– If you intend to use other than original equip-
ment wheels, be sure that they conform to
Porsche specifications for your model.
Only tires with the same make and with the
same specification code (e.g. “N0”, “N1”...)
can be mounted.
– The use of wheel rims and wheel bolts that do
not meet specifications of the original factory
installed equipment will affect the safe opera-
tion of your vehicle.
– Before you plan on exchanging wheels, or
snow tires already mounted on the wheel rims,
consult your authorized Porsche dealer. Your
dealer has the technical information necessary
to advise you which wheel rims and wheel bolts
are compatible with the original factory instal-
lations.
Danger!
Risk of loss of control and serious personal
injury or death.
fIf while driving, your vehicle experiences a sud-
den vibration or ride disturbance, and/or you
suspect that possible damage to your tires or
vehicle has occurred, you should immediately
reduce your speed without excessive use of
the brakes.
fStop the vehicle as soon as possible, and in-
spect the tires.
If you cannot determine the cause for the dis-
turbance, have your vehicle towed to the near-
est Porsche or tire dealer to have your vehicle
or tire(s) inspected.
fContinuing to operate the vehicle without cor-
rection could result in a loss of control and serious personal injury.

Practical Tips, Emergency Service
Uniform Tire Quality Grading Quality grades can be found where applicable on
the tire sidewall between tread shoulder and max-
imum section width.
ExampleAll passenger car tires must conform to Federal
Safety Requirements in addition to these grades. Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested un-
der controlled conditions on a specific govern-
ment test course.
For example, a tire graded 150 would wear one
and a half (1-1/2) times as well on the government
course as a tire graded 100.
The relative performance of tires depends upon
the actual conditions of their use, however, and
may depart significantly from the norm due to var-
iations in driving habits, service practices and dif-
ferences in road characteristics and climate.
