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 conditions,
can affect the braking performance.
Therefore have the brake fluid changed in accord-
ance with the change intervals stated in the
brochure “Maintenance”. – The warning lights on the instrument panel and
on the on-board computer indicate an insuffi-
cient brake fluid level.
– If the warning light lights up on the instrument
panel and the warning message appears on
the on-board computer in combination with a
larger pedal travel, a brake circuit may have
failed.
If the warning lights should light up when
driving:
fStop immediately in a suitable place.
fDo not continue driving.
Consult an authorized Porsche dealer.

Washer FluidCapacity: Approximately 6.3 quarts (6.0 liters). Washer fluidThe reservoir, with a blue screw cap, is in the front
luggage compartment, to the rear left.Clean water is generally not enough to clean the
windshield and headlights. Depending on the
season, mix the water with the appropriate
additives. Follow the instructions for the mixture
ratio.
Only use window cleaner concentrate which meets
the following requirements.
– Dilutability 1:100
– Phosphate-free
– Suitable for plastic headlight lenses.
We recommend window cleaner concentrates
approved by Porsche. Your authorized Porsche
dealer will be pleased to advise you.
Summer filling
Water + window cleaner concentrate at the mixing
ratio indicated on the container.
Winter filling
Water + antifreeze protection + window cleaner
concentrate at the mixing ratio indicated on the
container.
fPlease note all the information on the contain-
ers of the window cleaner concentrate or the
antifreeze protection.Topping off washer fluid
1. Please note all the information on the refill con-
tainer of the cleaning agent.
2. Open cap of the washer-fluid reservoir (arrow).
3. Top up washer fluid and close cap properly.
fDo not use engine coolant anti-freeze or any
other solution that can damage the car’s paint,
in the washer reservoir.

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.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.Light alloy wheels fPlease see the chapter “WASHING” on
Page 225.
Warning!
Danger of accident resulting in serious per-
sonal injury or death if cleaning agents (e.g.
wheel cleaning agents) come into contact
with the brake discs.The resulting film on the brake discs can im-
pair braking performance.
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.
Metal particles (such as brass or copper in brake
dust) must not remain too long on alloy wheels.
Contact corrosion can cause pitting.
Cleaners with an oxide-removing effect or the
wrong pH value, as are commonly used for other
metals, as well as mechanical tools and products,
will damage the oxide layer and are therefore
unsuitable.
fUse only cleaners for alloy wheels
(pH value 9.5). Products with the wrong
pH value can destroy the protective layer
on the wheels.
We recommend Porsche cleaner for alloy rims.
fIf possible, wash the wheels every two weeks
with a sponge or washing brush. If the wheels
are exposed to road salt, grit or industrial dust,
weekly cleaning is necessary.
Door, roof, lid and window seals
Caution!
The lubricant coating on the inner door
seals, convertible top and hardtop seals may
be damaged by unsuitable cleaning and care
agents.
fDo not use any chemical cleaning agents or
solvents.
fDo not use any preservative agents.
fWash dirt (e.g. abrasion, dust, road salt and
grit) from all seals regularly using warm soapy
water.
fIf there is a risk of frost, protect the outer door
seals and lid seals against freezing into place
with a suitable care product.Headlights, lights, interior and exterior
plastic parts, adhesive filmsUse only clean water and a little dishwashing
detergent to clean light lenses, plastic headlight
lenses, 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.
An interior window cleaner can also be used to
clean plastic surfaces (always read the cleaning
instructions on the container). We recommend
Porsche interior window cleaner.

Winter operation The capacity and ability of the battery to store
power decreases at low outside temperatures.
Moreover, the battery is more heavily loaded in
winter months, e.g. by the heated rear window,
more frequent use of additional lights, the fans
and the windshield wipers, etc.
fHave the battery checked before the start of
winter.
Maintenance note
Keep the battery well charged to prevent it
from freezing.
A discharged battery can freeze at 23 °F (--5 °C),
but a fully charged battery only freezes at -- 40 °F
(--40 °C).
A frozen battery must always be thawed before
connecting jump leads.
Replacing battery The service life of the battery is subject to normal
wear; it depends greatly on care, climatic condi-
tions, and driving conditions (distances, loads).
fOnly use an original Porsche battery, with the
correct part number, as a replacement.
fPlease observe the disposal instructions for
batteries.
Putting vehicle into operationAfter the battery is connected or after an exhaus-
tively discharged battery is charged, the multi-
functional PSM light lights up on the instrument
panel and a message appears on the on-board
computer to indicate a fault.
This fault can be remedied with a few simple
steps:
1. Start the engine.
2. With the vehicle stationary, perform a few
steering movements to the left and right and
then drive a short distance in a straight line
until the multifunctinal PSM light goes out and
the message on the on-board computer
disappears.
3. If the warnings do not disappear, then:
Drive carefully to the nearest authorized
Porsche dealer.
Have the fault remedied.
4. After the warnings disappear:
Stop the vehicle in a suitable place.
fPerform adaptation of the power windows:
