Maintenance, Car Care
Car Care Instructions fPlease see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 206.
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 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.
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.
fDo not use high-pressure cleaning equipment or steam cleaners for cleaning 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.
fPlease observe the operating instructions from
the unit manufacturer.
fWhen cleaning with a flat-jet nozzle or the like,
maintain a minimum distance of 20 inches (50
cm).
fNever use high-pressure cleaning units or
steam cleaners with a round-jet nozzle. A high-
pressure cleaning unit or steam cleaner with
round nozzle will damage your vehicle.
fThe tires are particularly susceptible to dam-
age.
fDo not point the cleaning jet directly at any of the aforementioned components.

Paint To protect the paint on your 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.
fDo not apply care products containing silicone
to the convertible top and windows.
General information
fNever rub a dusty vehicle with a dry cloth,
because the grains of dirt will damage the
paintwork.
fDo 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.
fPreserve paint regularly.
fApply 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
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.
fPlease see the chapter “VEHICLE DATA BANK”
on Page 284.
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 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.

Battery The battery is located in the luggage compart-
ment under a black plastic cover.
fPlease see the chapter “EMERGENCY OPERA-
TION – PULLING OUT THE IGNITION KEY” on
Page 76.
fPlease see the chapter “EMERGENCY UNLO-
CKING OF THE LUGGAGE COMPARTMENT LID”
on Page 260.
Warning!
Risk of short circuit, fire and damage to al-
ternerator and electronic control units, re-
sulting in serious personal injury or death.
fObserve all warning notes on the battery.
fDisconnect the negative terminal on the bat-
tery during all work on the electrical system.
fDo not lay tools or other metal objects on the
battery as they could cause a short circuit
across the battery terminal.
Hydrogen gas generated by the battery
could cause an explosion, resulting in
serious personal injury or death.
fDo not expose the battery to an open flame,
electrical spark or a lit cigarette.
fDo not wipe battery with a dry cloth.
Risk of serious personal injury or death and
damage to the fabric, metal or paint. fWear eye protection.
fDo not allow battery acid to come in contact
with your skin, eyes, fabric or painted
surfaces.
fIf you get electrolyte, which is an acid, in your
eyes or on your skin, immediately rinse with
cold water for several minutes and call a doc-
tor.
fSpilled electrolyte must be rinsed off at once
with a solution of baking soda and water to
neutralize the acid.
Battery posts, terminals and related acces-
sories contain lead and lead compounds,
chemicals known to the State of California to
cause cancer and reproductive harm.
fAlways protect your skin by washing thorough-
ly with soap and water.
Risk of explosion as a result of static charge,
resulting in serious personal injury or death.
fDo not wipe the battery with a dry cloth.
fEliminate potential electrostatic charge by
touching the vehicle before touching the bat-
tery.
Charge state A well-charged battery prevents starting problems
and has a longer service life.
Traffic density, requirements regarding noise, ex-
haust gas and fuel consumption reduce the engine
speed and, hence, the alternator output.
However, the large number of electrical loads has
markedly increased the demand for electrical
power.
In order to avoid discharging the battery
unintentionally:
fSwitch off unnecessary electrical loads in city
traffic, on short trips or in a line or traffic.
fAlways remove the ignition key from the igni-
tion switch when leaving the car.
fAvoid frequent operation of the convertible top
and operation of the Porsche Communication
Management system when the engine is not
running.
fIn the cold season in particular or if the vehicle
is used primarily for short journeys, it may be
necessary to recharge the battery from time to
time.

Emergency Starting with Jumper
Cables If the battery is discharged, e.g. in winter or after
the car has been parked for a long time, the bat-
tery of another car can be used for starting with
the help of jumper cables.
Make sure the voltage of both batteries is the
same. Both batteries must be 12 volt types.
The capacity (Ampere hours, Ah) of the booster
battery must not be substantially less than that of
the discharged battery.
The discharged battery must be correctly con-
nected to the vehicle’s electrical system.
