Maintenance and Car Care
Exercise Extreme Caution when
Working on your Vehicle
Danger!
Ignoring the following instructions may cau-
se 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
cautious of such devices such as hot water
heaters which ignite a flame intermittently.
fBefore working on any part in the engine
compartment, 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 you have to work on the engine while it is
running, always put the parking brake on and
put the gearshift lever in neutral or the
Tiptronic selector lever in position P or N.fIn particular, be very careful to ensure that
items of clothing (ties, shirt, sleeves etc.),
jewelry, long hair, hand or fingers cannot get
caught in the 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
engine off and exercise extreme caution.
fYour Porsche is equipped with an electronic
ignition system. When the ignition is on, high
voltage 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 support your car with safety stands if it
is necessary to work under the car. The jack
supplied with the car is not adequate for this
purpose.
For vehicles with air suspension with level
control and height adjustment switch off level
control.
Please see the chapter “RAISING VEHICLE
WITH THE JACK” on Page 192.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.
Withdraw ignition keys (switch ignition off in
vehicles that have Porsche Entry & Drive).
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
authorized Porsche dealer.
Improper maintenance during the warranty
period may affect your Porsche warranty
coverage.
fSupplies of fluids, e.g. engine oil, washer fluid,
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
vehicle. Please make enquiries before driving
abroad.

Wiper BladesMaintenance Notes
Wiper blades that are in perfect condition are vital
for a clear view.
fReplace the wiper blades twice per year
(before and after the cold season) or if wiper
performance deteriorates or the blades are
damaged.
fFor important information on “service topics”:
Please see the chapter “CAR CARE
INSTRUCTIONS” on Page 270.
Caution!
Risk of damage if wiper arm accidentally
falls back onto the windshield.
fAlways hold the wiper arm securely when
replacing the wiper blade.
Risk of damage if wiper blades that are
frozen in place are loosened improperly.
fThaw the wiper blades before loosening them.
Risk of damage.
If the wiper blades are not changed properly,
they can come loose when the car is moving.
fCheck whether the wiper blades are seated
securely.
The wiper blade must be pushed onto the wiper arm up to the stop. fPeriodically clean the wiper blades with
window cleaner, especially after the vehicle
has been washed in a car wash.
We recommend the Porsche window cleaner. If
they are very dirty (e.g. with insect remains),
they can be cleaned with a sponge or cloth.
If the wiper blades rub or squeak, this may be as
a result of the following:
– If the vehicle is washed in an automatic car
wash, wax residues may adhere to the wind-
shield. These wax residues can be removed
only by using window cleaner concentrate.
fPlease see the chapter “WASHER FLUID” on
Page 258.
Please contact your authorized Porsche dealer for
further information.
– The wiper blades may be damaged or worn.
fReplace damaged or worn wiper blades as
soon as possible.
Replacing wiper blades at frontfApply the parking brake.
fSwitch the windshield wipers off (wiper stalk in
position 0).
fSwitch ignition off.
1. Fold windshield wiper arm away from the
windshield (arrow 1).

Emission Control SystemIn the interest of clean airPollution of our environment has become a
problem that is of increasing concern to all of us.
We urge you to join us in our efforts for cleaner air
in controlling the pollutants emitted from the auto-
mobile.
Porsche has developed an emission control
system that controls or reduces those parts of the
emission that can be harmful to our environment.
Your Porsche is equipped with such a system.
Porsche warrants the Emission Control System in
your new car under the terms and conditions set
forth in the Warranty Booklet.
You, as the owner of the vehicle, have the respon-
sibility to provide regular maintenance service for
the vehicle and to keep a record of all mainte-
nance work performed. To facilitate record
keeping, have the service performed by
authorized Porsche dealers. They have Porsche
trained technicians and special tools to provide
fast and efficient service.To assure efficient operation of the Emission
Control System:
fHave your vehicle maintained properly and in
accordance with the recommendations
described in your Maintenance Booklet. Lack
of proper maintenance, as well as improper
use of the vehicle, will impair the function of
the emission control system and could lead to
damage.
fDo not alter or remove any component of the
emission control system.
fDo not alter or remove any device, such as
heat shields, switches, ignition wires, valves,
etc., which are designed to protect your
vehicle's emission control system. In addition
to serious engine damage, this can result in a
fire if excess raw fuel reaches the exhaust
system.
fDo not continue to operate your vehicle if you
detect engine misfire or other unusual opera-
ting conditions.

The catalytic converters will be damaged by:
– push or tow starting the vehicle
– misfiring of the engine
– turning off the ignition while the vehicle is
moving or
– driving until the fuel tank is completely empty
– by other unusual operating conditions.
fDo not continue to operate your vehicle under
these conditions, since raw fuel might reach
the catalytic converters. This could result in
overheating of the converters. Federal law
prohibits use of leaded fuel in this car.
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.
fAlways monitor your fuel consumption.
fDrive smoothly, avoid abrupt changes in speed
as much as possible.
fAvoid jack rabbit starts and sudden stops.
fDo not drive longer than necessary in the lower
gears. Shifting into a higher gear early without
lugging the engine will help save fuel.
fProlonged “warm up” idling wastes gas. Start
the vehicle just before you are ready to drive.
Accelerate slowly and smoothly.fSwitch off the engine if stationary for longer
periods.
fAny additional weight carried in the vehicle
re d u c e s f u e l e c o n o m y. A l w a ys k e e p c a rg o t o a
minimum and remove all unnecessary items.
fOrganize your trips to take in several errands
in one trip.
fAll electrical accessories contribute to
increased fuel consumption.
fOnly switch on the air conditioning when neces-
sary.
fDo not drive with the Roof 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 will probably be less
than the estimated mpg.
fPlease see all local and national speed limits.

Maintenance and Car Care
Operating Your Porsche in other
CountriesGovernment regulations in the United States and
Canada require that automobiles meet specific
emission regulations and safety standards. There-
fore, cars built for the U.S. and Canada differ from
vehicles sold in other countries.
If you plan to take your Porsche outside the conti-
nental 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. Excessive 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 me-
chanical damage that could result because
of inadequate fuel, service or parts availabi-
lity.
If you purchased your Porsche abroad and want to
bring it back home, be sure to find out about ship-
ping and forwarding requirements, as well as
current import and customs regulations.
Fuel
Warning!
Fuel is highly flammable and harmful to
health.
fFire, open flame and smoking are prohibited
when handling fuel.
fAvoid contact with skin or clothing.
fDo not inhale fuel vapours.
To prevent damage to the emission control
system and engine:
fNever drive the tank completely out of fuel.
fAvoid high cornering speeds after the warning lights have come on.
To avoid permanent damage to the functionality of
the catalytic converters and oxygen sensors, use
only unleaded fuel.
The engine is designed to provide optimum
performance and fuel consumption if unleaded
premium fuel with 98 RON/88 MON is used.
If unleaded premium fuels with octane numbers of
at least 95 RON/85 MON are used, the
engine's knock control automatically adapts the
ignition timing.The emission control system can be damaged in
various ways (e.g. fueling incorrectly, shortage of
fuel, tow-starting).
fPlease see the chapter “HOW EMISSION
CONTROL WORKS” on Page 264.
fPlease see the chapter “DISPLAYING STATUS
OF LEVEL CONTROL” on Page 131.

RefuelingfTotal capacity approx. 26.4 gallons
(100 liters), including approx. 3 gallons
(12 liters) reserve.
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.
fDo 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. Slowly unscrew the tank cap.
Hang the tank cap’s plastic strap on the
hookA on the inside wall of the filler flap.
3. Insert pump nozzle fully into the filler neck with
the handle of the pump nozzle facing down.
4. Do not add further fuel once the correctly
operated automatic pump nozzle has switched
off.
Fuel could spray or could run over when
heated.
5. Replace the tank cap immediately after
refueling and turn it until you hear it and feel it
engage.Maintenance Note
If you lose the tank filler cap, you must replace it
only with an original part.
Caution!
Risk of damage. Decorative foils may bleach
of they come into contact with fuel.
fWipe off any spilt fuel immediately.Portable Fuel Containers
Danger!
Portable fuel containers, full or partially
empty, may leak causing an explosion, or
result in fire in case of an accident.
fNever carry additional fuel in portable contai-ners in your vehicle.
