Power Steering
Warning!
Risk of accident resulti ng in serious personal
injury or death.
When the engine is stopped (e.g. when being
towed) or the hydraulic system fails, there is
no assistance for steering.
Therefore, substantially more force will have
to be exerted in order to steer.
f Exercise great care when being towed.
f Have the fault remedied at your nearest autho-rized Porsche dealer.
Note
The flow noise heard at full steering lock is system
related and does not indi cate a defect in the
steering system.
Checking hydraulic fluid f Please see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 196.
The hydraulic fluid reservoir is located in the engi-
ne compartment.
Regular checking of hydraulic fluid is part of
servicing.
Air Filter A dirty air filter not only reduces engine perform-
ance, but can lead to premature engine wear.
Regular filter replacement is part of the routine
maintenance service.
f In dusty conditions, check the filter element
more frequently and replace if necessary.Combination Filter The fresh air passing through the combination fil-
ter into the passenger co mpartment is virtually
free of dust, pollen, and unpleasant odors.
f If the outside air is polluted by exhaust fumes,
press the circulating-air button.
A dirty filter can be the cause of reduced air flow:
f Have filter replaced by your authorized
Porsche dealer.
Regular filter replacement is part of the routine
maintenance service.
Fluids/Oils for Manual
Transmission and Porsche
Doppelkupplung (PDK)The transmission fluids/oils have to be checked
and changed at the intervals listed in your Mainte-
nance Schedule.
f Please see the chapter “CAPACITIES” on
Page 281.
Do not tow the car or run the engine without fluid/
oil in the transmission. The transmission may be
damaged by even a tiny speck of dirt, only a clean
funnel or spout must be used when adding fluid/
oil.
We recommend that you have the fluids/oils
changed at your Porsche dealer, who has the re-
quired lubricants and the necessary filling equip-
ment.
f If you suspect an oil leak in the transmission,
have your authorized Porsche dealer check it
out immediately.

216
Maintenance, Car Care
f
Do not treat matt-painted components with
preservatives or polishes, 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 normal 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 coa t. The paint code and color
number are found on the da ta bank in the Mainte-
nance booklet.
f Please see the chapter “VEHICLE DATA BANK”
on Page 274.
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 pr eservative 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.
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 se ason. 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 the 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 le ather 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.

Maintenance, Car Care
217
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.
fPlease see the chapter “WIPER BLADES” on
Page 212.
f Replace the wiper blades twice per year (be-
fore and after the cold season) or whenever
wiper performance deteriorates or the blades
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.
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, residues may adhere to the windshield.
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 imme-
diately.
f Please see the chapter “WASHER FLUID” on
Page 210.
f Please contact your authorized Porsche dealer
for further information.
Undercoating As it is not possible to ex clude 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 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 so und-proofing materials ap-
plied at the factory.
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 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.
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.

Maintenance, Car Care
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.
Storing your Porsche If you intend to store yo ur 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.
f Clean 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.
f Fill up the fuel tank.
f Change the oil and oil filter, and run the engine
for several minutes.
f Increase the tire pressure to 50 psi (3.5 bar).
It is not recommended to lift the vehicle, due to
the possibility of corros ion 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
f Check and correct antifr eeze/cleaning solution
level as necessary. Electrical system
f
Remove 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.
f Recharge 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.
f Please see the chapter “BATTERY” on
Page 249.
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.

222
Practical Tips, Emergency Service
Exercise Extreme Caution when
Working on your Vehicle
Danger!
Ignoring the following instructions may
cause serious personal injury or death.
f The engine compartment of any motor vehicle
is a potentially hazardou s 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.
f O 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.
f Ensure 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.
f Before 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.
f Be 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 PDK selector lever in position P or N. f
In particular, be very careful to ensure that
items of clothing (ties, shirt, sleeves etc.),
jewelry, 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 in
the engine-compartment.
The fans 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.
f Your Porsche is equipped with an electronic ig-
nition system. When the ig nition 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.
f Always support your car with safety stands if it
is necessary to work under the car.
Jacks are not suitable for this kind of work.
f When 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. f
Do not smoke or allow an open flame around
the battery or fuel.
Keep a fire extinguisher in close reach.
f Incomplete 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.
f Supplies 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.
f Some countries require additional tools and
special spare parts to be carried.
Please make enquiries before driving abroad.
