Maintenance and Car Care
Fuel EconomyFuel economy will vary depending on where,
when and how you drive, optional equipment
installed, and the general condition of your
car.
A car tuned to specifications and correctly
maintained, will help you to achieve optimal
fuel economy.
fHave your vehicle tuned to specifications. Air
cleaner should be dirt free to allow proper
engine “breathing”.
Battery should be fully charged.
Wheels should be properly aligned.
Tires should be inflated to the correct
pressure.
f Always monitor your fuel consumption.
f Drive smoothly, avoid abrupt changes in speed
as much as possible.
f Avoid jack rabbit starts and sudden stops.
f Do not drive longer than necessary in the lower
gears. Shifting into a higher gear early without
lugging the engine will help save fuel.
f Prolonged “warm up” idling wastes gas. Start
the vehicle just before you are ready to drive.
Accelerate slowly and smoothly.
f Switch off the engine if stationary for longer
periods.
f Any additional weight carried in the vehicle
reduces fuel economy. Always keep cargo to
a minimum and remove all unnecessary items. f
Organize your trips to take in several errands
in one trip.
f All electrical accessories contribute to
increased fuel consumption.
f Only switch on the air conditioning when
necessary.
f Do not drive with the Ro of Transport System
mounted unless you need it.
The EPA estimated miles per gallon (mpg) is
to be used for comparison purposes, actual
mileage may be different from the estimated
mpg, depending on your driving speed,
weather conditions and trip length. Your
actual highway mileage may be less than the
estimated mpg.
f Please observe all local and national speed
limits.
Operating Your Porsche in other
CountriesGovernment regulations in the United States and
Canada require that automobiles meet specific
emission regulations and safety standards.
Therefore, cars built for the U.S. and Canada differ
from vehicles sold in other countries.
If you plan to take your Porsche outside the
continental limits of the United States or Canada,
there is the possibility that
– unleaded fuel may not be available;
– unleaded fuel may have a considerably lower
octane rating. Excessi ve engine knock and
serious damage to both engine and catalytic
converters could result;
– service may be inadequate due to lack of proper service facilities, tools or diagnostic
equipment;
– replacement parts may not be available or very difficult to get.
Porsche cannot be responsible for the
mechanical damage that could result
because of inadequate fuel, service or parts
availability.
If you purchased your Porsche abroad and want to
bring it back home, be sure to find out about
shipping and forwarding requirements, as well as
current import and customs regulations.

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.
It is important that the service intervals,
particularly the oil change intervals, are
observed in accordance with the specifications
in the “Maintenance” booklet.

Maintenance and Car Care
Refuelling
Danger!
The RF energy from a cellphone can cause a
sparking on bare metal, much like aluminum
foil in a microwave oven. The spark could
ignite gasoline fumes present while refuling.
Static discharge from your body can ignite
gasoline fumes present when you get back
out of the vehicle and touch the fuel nozzle.
In either case, resulting fire can cause
serious damage to the vehicle, serious injury
or death to persons in immediate vicinity.
f Do not use a cellphone while pumping gas.
fDo not re-enter the vehicle while pumping gas.
1. Stop the engine and switch off the ignition.
2 . O p e n t h e f i l l e r f l a p b y p re s s i n g o n t h e re a r p a r t of the filler flap ( arrow).

6. Operate the pump nozzle and refuel the vehicle.
Do not add further fuel once the correctly
operated automatic pump nozzle has switched
off. Fuel could spray back or could flow over
when heated.
7. Replace the tank cap immediately after refuelling and close it until you hear and feel
it locking.
8. Close the filler flap and press on the rear of the filler flap until it engages securely.
If you lose the tank filler cap, you must
replace it only with an original part.
Caution!
Risk of damage. Decorative foils may fade
if they come into contact with fuel.
f Wipe off any spilled fuel immediately. Emergency unlocking of the filler flap
If the electrical unlocking mechanism is faulty,
the filler flap can be opened as follows:
– Pull the emergency release mechanism behind
the right luggage compartment trim panel in
direction of arrow .
The filler flap pops open.
Fuel Can
Danger!
Risk of fire or explosion if the fuel can is
damaged in an accident and fuel escapes.
Escaping vapors can be harmful to health.
f Do not carry a fuel can on journeys.
fObserve the relevant laws.

Maintenance and Car Care
Fuel Recommendations Your Porsche is equipped with catalytic
converters and must use UNLEADED FUEL
ONLY .
Your engine is designed to provide optimum
performance and fuel economy using unleaded
premium fuel with an octane rating of 98 RON
(93 CLC or AKI) . Porsche therefore
recommends the use of these fuels in your
vehicle.
Porsche also recognizes that these fuels may not
always be available. Be assured that your vehicle
will operate properly on unleaded premium fuels
with octane numbers of at least 95 RON
(90 CLC or AKI) , since the engine’s “Electronic
Oktane™ knock control” will adapt the ignition
timing, if necessary.
It is important to observe the regular service
intervals, and particularly the oil change intervals,
specified in the “Maintenance” booklet.
T h e u s e o f U N L E A D E D F U E L O N LY i s c r i t i c a l l y
important to the life of the catalytic
converters. Deposits fr om leaded fuels will
ruin the converters and make them
ineffective as an emis sion control device.
Cars with catalytic converters have a smaller fuel
tank opening, and gas station pumps that
dispense unleaded fuel ha ve smaller nozzles. This
will prevent accidental pumping of leaded fuel into
cars with catalytic converters. Unleaded fuels may not be available outside the
continental U.S. and Canada. Therefore, we
recommend you do not take your car to areas or
countries where unleaded fuel may not be
available.
Octane ratings Octane rating indicates a fuel’s ability to resist
detonation. Therefore, buying the correct octane
gas is important to prevent engine “damage”.
The RON octane rating is based on the research
method. The CLC (U.S.
Cost of Living Council
octane rating) or AKI ( anti knock index) octane
rating usually displayed on U.S. fuel pumps is
calculated as research octane number plus motor
octane number, divided by 2, that is written as:
The CLC or AKI octane rating is usually lower than
the RON rating:
For example: 95 RON equals 90 CLC or AKI.
Fuels containing ethanolDo not use any fuels containing more than 10
percent ethanol by volume.
We recommend, however, to change to a different
fuel or station if any of the following problems
occur with your vehicle:
– Deterioration of driveability and performance.
– Substantially reduced fuel economy.
– Vapor lock and non-start problems, especially at high altitude or at high temperature.
– Engine malfunction or stalling.

Fuel Evaporation Control Fuel tank venting The evaporation chamber and the carbon canister
prevent fuel vapors from escaping to the
atmosphere at extreme high outside
temperatures, when driving abruptly around
curves and when the car is parked at an incline or
in any other nonlevel position. Vapor control system and storage When the fuel tank is filled, vapors are collected in
the evaporation chamber by a vent line leading the
vapors to the carbon canister where they are
stored as long as the engine does not run. Purge system When the engine is running, the fuel vapors from
the canister will be mixed with fresh air from the
ambient air of the canister. This mixture will be
directed to the intake air housing by the tank vent
line, mixed with the intake air and burned during
normal combustion.
Car Care Instructionsf Please see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on page 252.
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.
f Keep cleaning agents out of reach from
children.
f Observe all caution labels.
f Always read directions on the container before
using any product. These directions may
contain information necessary to avoid
personal injury.
f Do 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.
f Do not clean the underside of chassis,
fenders, wheel covers, etc., without protecting
your hands and arms as you may cut yourself on sharp-edged metal parts.

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
271
fStart washing the vehicle by thoroughly
wetting the paintwork and rinsing the heavy
dirt off.
f After washing the vehicle, rinse it thoroughly
with water and rub it dry with chamois-leather.
Do not use the same chamois for rubbing
dry as you use for cleaning the windshield
and windows.
Warning!
Risk of accidents! Reduced or uneven
braking action may be caused by wet
brakes.
f After washing the vehicle, test the brakes
and steering and briefly brake the discs dry.
When doing so, make sure that vehicles travelling behind you are not affected. Cleaning in car washes
Optional add-on parts or parts that project beyond
the contours of the vehi
cle may be damaged by
design features of car washes.
The following parts are particularly at risk:
– Windshield wipers and rear wiper (always switch them off – wiper stalk in
position 0 – to prevent them wiping
unintentionally in intermittent or sensor
operation).
– Exterior mirrors (always fold in).
– External antenna (always unscrew).
– Roof transport system (always remove completely).
– Spoiler.
– Wheels (the wider the rim and the lower the tire height, the greater the risk of damage).
f Please consult the operator before using
automatic car washes.
f All parts not reached by a car wash, such
as door and lid seams or door sills, must
be washed and polished by hand.
Paint careIn order to protect the pa int 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.
General Notes
f Never rub a dusty vehicle with a dry cloth,
because the grains of dirt will damage
the paintwork.
f Do not treat matt-painted components with
preservatives or polishes as these remove
the matt effect.
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 shin y and elastic. Dirt is
prevented from adhering to the paint surface and
industrial dust is prevented from penetrating
the paint.
