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 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 or the se-
lector lever is in position P or N. 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 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 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 place the vehicle on stable supports if
work has to be carried out under the vehicle.
Jacks are not suitable for this kind of work.
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 can-
not be started.
Remove the ignition key. fDo not smoke or allow an open flame around
the battery or fuel.
Keep a fire extinguisher close at hand.
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 in your vehi-
cle.
Please make enquiries before driving abroad.
Power measurements Power measurements on dynamometers are not
approved by Porsche. Working in the engine compartmentHave the necessary work in the engine compart-
ment done by a qualified specialist workshop.
We recommend that you use your authorized
Porsche dealer for carrying out this work.

Brake Fluid Level fPlease observe the chapter “EXERCISE EXTRE-
ME CAUTION WHEN WORKING ON YOUR VE-
HICLE” on Page 172.
fUse only new (unused) Original Porsche
brake fluid.
Warning!
Brake fluid is hazardous to your health, and
may be fatal if swallowed.
Brake fluid also attacks paintwork.
fKeep brake fluid out of children’s reach.
fTake care while topping off brake fluid not to
soil the luggage compartment or items of lug-gage.
Checking the brake fluid level The reservoir for the hydraulic braking and clutch
systems is in the front luggage compartment.
1. Open and remove cover flap A.
2. Regularly check the brake-fluid level on the
transparent expansion tank through the win-
dow B.
The fluid level should always lie between the
“Min” and “Max” marks. A slight decrease in the fluid level due to wear and
automatic readjustment of the disc brakes is nor-
mal.
If, however, the fluid level falls markedly or below
the “Min” mark, the braking system may have de-
veloped a leak.
fHave the braking system checked immediately
at an authorized Porsche dealer.

Changing the brake fluid Brake fluid absorbs moisture from the air over
time. This accumulation of water lowers the boil-
ing point and, under certain operating con ditions,
can affect braking performance.
Therefore have the brake fluid changed in accord-
ance with the change intervals stated in the bro-
chure “Maintenance”. The brake-fluid warning lights in the instrument
panel and on-board computer indicate:
– brake-fluid level too low,
– in conjunction with large pedal travel, braking-
circuit failure.
If the warning lights should light up while
driving:
fStop immediately in a suitable place.
fDo not continue driving.
Please have the fault remedied at your nearest
authorized Porsche dealer.

Car Care Instructions fPlease observe the chapter “EXERCISE EXTRE-
ME CAUTION WHEN WORKING ON YOUR VE-
HICLE” on Page 172.
Regular and correct care helps to maintain
the value of your car and is also a precondi-
tion 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
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).

Light alloy wheels fPlease observe the chapter “WASHING” on
Page 196.
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 dis-
coloration 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.
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 woolen
cloth or a commercially available microfiber
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.
