Maintenance and Car Care
Engine OilIt is important to perform oil changes regularly in
accordance with the intervals specified in your
Maintenance Schedule.Engine oil consumptionIt is normal for your engine to consume oil.
The rate of oil consumption depends on the quality
and viscosity of oil, the speed at which the engine
is operated, the climate, road conditions as well
as the amount of dilution and oxidation of the
lubricant.
If the vehicle is used for repeated short trips, and
consumes a normal amount of oil, the engine oil
measurement may not show any drop in the oil
level at all, even afte r 600 miles (1000 km) or
more. This is because the oil is gradually
becoming diluted with fuel or moisture, making it
appear that the oil level has not changed.
The diluting ingredients evaporate out when the
vehicle is driven at high speeds, as on an
expressway, making it then appear that oil is
excessively consumed after driving at high
speeds.
If the conditions you drive your vehicle in are
dusty, humid, or hot, the frequency of the oil
change intervals should be greater. If the vehicle is driven at a high rate of speed,
climatic conditions are warm, and the load is high,
the oil should be checked more frequently, as
driving conditions will de
termine the rate of oil
consumption.
– The engine in your vehicle depends on oil to lubricate and cool all of its moving parts.
Therefore, the engine oil should be checked
regularly and kept at the required level.
– Make it a habit to have the engine oil level checked with every refueling.
– The oil pressure warning light is not an oil level indicator.
The oil pressure warning light indicates serious
engine damage may be occuring when lit, if
engine rpm is above idle speed.
Checking Engine-Oil Levelf Check the oil level on the multi-function display
at regular intervals before refuelling.
f Please see the chapter “OIL LEVEL DISPLAY
AND MEASUREMENT OF THE ENGINE OIL
LEVEL” on page 121.
Warning!
Engine oil is hazardous to your health and
may be fatal if swallowed.
f Keep engine oil out of children's reach.
Used engine oil contains chemicals that have
caused cancer in laboratory animals.
f Always protect your skin by washing thoroughly with soap and water.
Top-up quantity
The difference between the minimum and
maximum marks on the segment display is
approx. 1.06 US quearts (1 liter).
One segment of the display corresponds to
a top-up quantity of approx. 0.26 US quarts
(0.25 liters).
f Never add more engine oil than required to
reach the maximum mark.

FuelWhen the ignition is on, the fuel level is displayed
on the instrument panel.
fPlease see the chapter “FUEL GAUGE” on
page 111.
Warning!
Fuel is highly flammable and harmful to
health.
f Fire, open flame and smoking are prohibited
when handling fuel.
f Avoid contact with skin or clothing, since injury
to your skin may occur.
f Do not inhale fuel vapors, since they may make
you ill and possibly cause death if inhalation is
prolonged and occurs in a closed space.
To prevent damage to the emission control
system and engine:
f Never drive the tank dry.
f Avoid high cornering speeds after the warning lights have come on.
f Please see the chapter “FUEL ECONOMY” on
page 264. To avoid permanent damage
to the functionality of
the catalytic converters and oxygen sensors, use
unleaded fuel only.
The engine is designed to provide optimum
performance and fuel consumption if unleaded
premium fuel with 98 RON/88 MON is used.
If unleaded fuels with octane ratings of less than
98 RON/88 MON are used, the engine’s knock
control automatically adapts the ignition timing.
Porsche recommends that you use fuel with
at least 95 RON/85 MON in your vehicle.
The emission control system can be damaged in
various ways (e.g. fueling incorrectly, shortage of
fuel, tow-starting).
f Please see the chapter “HOW EMISSION
CONTROL WORKS” on page 263. Note on operation
Information on the fuel quality can normally
be found on the pump.
If this is not the case, ask a fuel station attendant.
If the recommended fuel
is not available, you
can also use unleaded regular fuel (91 RON/
82.5 MON) in an emergency.
However, this could reduce performance and
increase fuel consumption.
f Avoiding driving at full throttle.
In some countries the available fuel quality may
not meet requirements and can result in coking
around the inlet valve.
In this case, the fuel may be mixed with the
additive sold and recommended by Porsche after
consulting a authorized Porsche dealer.
Porsche part number 000 043 206 89.
f Observe the instructions and mixture ratios
stated on the container.

Maintenance and Car Care
High-pressure cleaning equipment
Warning!
High-pressure cleaning equipment can
damage the following components:
–Tires
– Logos, emblems, decorative foils
– Painted surfaces
– Alternator, valve covers
– ParkAssist sensors
– Radar sensor for adaptive cruise control
– Rearview camera
f Always read the operating instructions
provided by the equipment manufacturer.
f Always cover the lid of the brake fluid reservoir
prior to cleaning. Never point the cleaning jet
directly at the lid.
f When cleaning with a flat-jet nozzle or
a so-called “dirt blaster”. maintain a minimum
distance of 20 in. (50 cm).
f Never use high-pressure cleaning equipment
with a round-jet nozzle.
A high-pressure cleaning device fitted with
a round nozzle will damage your vehicle. The
tires are particularly susceptible to damage.
f Do not point the cleaning jet directly at any of the aforementioned components.
Decorative film
Caution!
Risk of damage due to separation of the
decorative film when using high-pressure
cleaning equipment.
f When cleaning components, the water must
not be hotter than 140 °F (60 °C) and the
pressure no greater than 580 psi (40 bar).
Always observe a minimum distance of 20 in. (50 cm).
Care of door lockfTo prevent the door lock from freezing
during the cold season, cover the lock barrel
with suitable adhesive tape while washing
the vehicle.
If the lock still freezes, use an ordinary de-icer.
In many cases, a well warmed key can help.
Never use excessive force.
Car washingThe best protection for the vehicle from the
damaging effects of the environment is frequent
washing and preservation.
The longer road salt, road dust, industrial dust,
insect remains, bird excrement, and tree sap,
resin, pollen, etc. are allowed to remain on the
bodywork, the more harmful their effect.
Observe the following poi nts in order to ensure
that the vehicle is washed thoroughly without
damaging the paintwork:
f The underside of the vehicle should also be
thoroughly washed at the end of the winter
season at the latest.
f Wash your vehicle only at sites provided for
this purpose to prevent soot, grease, oil and
heavy metals from entering the environment.
f Dark colors are slightly more susceptible
to scratching and require particularly careful
paint care.
Dark paints make even the smallest surface
blemishes (scratches) more conspicuous than
lighter colors.
f Do not wash your Porsche in direct sunlight
or when its body is hot.
f When washing by hand, use a car shampoo,
plenty of water, and a soft sponge or washing
brush.
We recommend Porsche car shampoo.

Maintenance and Car Care
Cleaning headlights, lights, interior and
exterior plastic components, adhesive
foils, radar sensor for adaptive cruise
control and rearview cameraObserve the following points:
fUse only clean water and a little dishwashing
liquid or interior window cleaner to clean
headlights, lights, plastic components
and surfaces.
Use a soft sponge or a soft, lint-free cloth.
Note
An interior window cleane r can also be used to
clean plastic surfaces (always read the cleaning
instructions on the container!).
We recommend Porsche interior window cleaner.
f Gently wipe the surface without applying
too much pressure.
f Do not clean when dry.
f Never use other chemical cleaners
or solvents.
f Rinse cleaned surfaces with clear water.
Alloy wheelsMetal particles (e.g. brass or copper in brake
dust) must not remain too long on alloy wheels.
Contact corrosion can cause pitting.
Note
Cleaners with an oxide-removing effect or
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 light
alloy rims.
f If 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.
f Every three months, after cleaning, treat the
wheels with car wax or an acid-free grease
(e.g. Vaseline).
Rub the grease in well with a soft cloth.
f Please see the chapter “CLEANING IN CAR
WASHES” on page 271.
Danger!
Danger of accident resulting in serious
personal 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 impair braking
performance.
f Make sure that no clea ning agent comes into
contact with the brake discs.
f If cleaning agent has come into contact with
the brake discs, clean the brake discs
thoroughly with a strong jet of water.
f Paying attention to any road users behind you, dry the brake discs by applying the brakes.
Stainless steel tailpipesStainless steel tailpipes can discolor due to
soiling, strong heat and combustion residues.
The original shine can be achieved again using
commercially available metal lustre paste or metal
polish.
