Cleaning the engine compartment
Caution!
Risk of damage, e.g. to the alternator, paint-
ed surfaces, and the valve covers.
fNever use high-pressure cleaning units with a
round-jet nozzle.
fAlways maintain a minimum distance of 21 in.
(50 cm).
fAlways cover the lid over the brake fluid reser-
voir prior to cleaning with a high-pressure
cleaner. Never point the cleaning jet directly at
the lid.
fDo not point the cleaning jet directly at any of the aforementioned components.
Note on operation
If the car is driven off-road frequently and after
driving on salted or gritted roads:
fClean the engine compartment regularly.
WindowsThe 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.
fMake sure not to damage the TV antenna in the
side window when cleaning.
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 pol-
ish and could smear the windows and thus im-
pair vision.
fRemove dead insects with insect remover.
Wiper bladesWiper 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 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.

Maintenance, Car Care
271
Headlights, lights, interior and exterior
plastic partsfUseonlyclean water and a little dishwashing
detergent to clean headlights, lights, 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
suitable for cleaning plastic surfaces.
Follow the cleaning instructions on the
container.
Never use other chemical cleaners or
solvents.
fRinse cleaned surfaces with clear water.
Door, roof, lid and window sealsfWash dirt (e.g. abrasion, dust, road salt or grit)
from all seals regularly using warm soapy wa-
ter. Do not use any chemical cleaning agents
or solvents.
When there is a frost hazard, the outer door seals
and the lid seals can be protected against freezing
into place by a suitable care product.
In order to prevent damage to the anti-fric-
tion coating, the inner door seals must not be
treated with care products.
Light alloy wheelsfPlease observe the chapter “AUTOMATIC CAR
WASHES” on Page 267.
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 too
long.
fIf possible, wash the wheels with a sponge or
wash brush about every two weeks. In areas
where road salt or grit 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 in-
corect, 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
(e.g. vaseline).
Using a clean cloth thoroughly rub the grease
into the surface.

Maintenance, Car Care
Leather careCharacteristics 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 completely with dye on production. “Na-
ture’s signature” is therefore easily recogniz-
able.This fine material is distinguished by an out-
standing seating comfort, special suppleness and
a typical 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.
Carpets and matsfUse only a vacuum cleaner or a medium stiff
brush.
fRemove stains and spots with Porsche stain
remover.
The Porsche range of accessories includes 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 lie them
loosely in the vehicle.
Your Porsche dealer will be glad to offer you
floor mats of correct size including a securing possibility.

Airbags
Danger!
There is a danger of serious personal injury
or death if the airbag system is impaired by
improper cleaning work.
fDo not make any modifications whatsoever on
individual components such as the padded
covers of the steering wheel, the front seats,
the roof pillars and the rooflinings.
fLet your authorized Porsche dealer clean these components.
Fabric liningsFabric linings on pillars, headliner and sun visors,
etc., must be treated only using suitable cleaning
agents or a suitable dry foam and a soft brush.
AlcantarafDo not use a leather care product to clean Al-
cantara.
For regular care it is sufficient to clean the cover
with a soft brush.
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 beltsfUse a mild detergent to clean soiled belts.
fWhen drying, avoid direct sunlight.
fOnly use suitable cleaning agents.
fDo not tint or bleach the belts.
The belt fabric could be weakened, thus affect-
ing safety.

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 pis-
ton shafts.The vehicle should be moved slight-
ly, approximately 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 “CHARGE STATE”
on Page 320.Vehicle interior

Practical Tips, Minor Repairs
Tire pressures
Danger!
Risk of accident.
Risk of serious personal injury or death.
Driving the vehicle with low tire pressure
increases risk of a tire failure and resulting
loss of control. Furthermore, low tire pres-
sure increases rate of wear of the affected
tires and cause damage. Always use an
accurate tire pressure gauge when checking
inflation pressures.
fDo not exceed the maximum tire pressure
listed on the tire sidewall. (Also refer to “Tech-
nical data“).
fCold tire inflation pressure means: all tires
must be cold, ambient temperature maximum
68°F (20°C), when adjusting the inflation pres-
sure. Avoid sunlight striking the tires before
measuring cold pressures, since the pressures
would rise from temperature influence.
fValve caps protect the valve from dust and dirt,
and thus from leakage. Always screw caps
tightly down. Replace missing caps immedi-
ately.
fFor safety reasons, don't use tire inflating bot-tles.The tire pressure must match the prescribed
value.
You can find information on the tire pressure:
– In the front left door aperture.
– Please observe the chapter “TIRE
PRESSURES, COLD” on Page 361.
These values are for cold tires (68°F/20 °C).
fCheck the tire pressure at least every
2 weeks. Always check when tires are cold.
fOn vehicles with tire pressure monitoring
system:
Please observe the chapter “TIRE PRESSURE
MENU” on Page 89.
When tires are warm, the tire pressure is
increased.
fNever let air out of hot tires. This could cause
the tire pressure to fall below the prescribed
value.
Insufficient tire pressure can cause tires to
overheat and thus be damaged – even invisibly.
Hidden tire damage is not eliminated by subse-
quently correcting the tire pressure.Overloading
Danger!
Risk of personal injury, loss of control and
damage to vehicle parts.
fDo not overload your vehicle. Be careful about
the roof load.
fIf loading the vehicle also correct the tire pres-
sure. Tire pressure for loaded vehicle can be
found on the tire pressure plate and in the
chapter technical data.
fNever exceed the specified axle load.
Overloading can shorten the service life of the
tires and car, as well as lead to dangerous vehi-
cle reactions and long braking distances.
Damage due to overloading is not covered by the vehicle warranty.
fPlease observe the chapter “LOADING INFOR-
MATION” on Page 195.
fPlease observe the chapter “TIRE PRES-
SURES, COLD” on Page 361.

V = up to 150 mph (240 km/h)
W = up to 167 mph (270 km/h)
Y = up to 186 mph (300 km/h)
Tip on driving
Tires with a maximum speed rating that is lower
than the specified maximum vehicle speed may be
mounted only if they bear an M+S identification on
the tire sidewall.
fPlease note that in addition to the winter tires,
all-season and all-terrain tires are also subject
to speed limits and bear this identification.
fPlease observe the chapter “SPEED LIMITS
FOR TIRES” on Page 91.
