Engine Oil RecommendationPorsche recommends  .
The right oil for your vehicle.1) Generally, you can find details of the 
manufacturer approvals on the oil containers or as 
a notice displayed by the retailer.
The current approval status is also available from 
your Porsche partner.2) SAE viscosity class - Example: SAE 0W - 40 
Specification 0W = Viscosity specification for 
low temperatures (winter).
Specification 40 = Viscosity specification for 
high temperatures.3) For all temperature ranges.4) For the temperature range over --13 °F (--25 °C).Always observe the following points:
– Use engine oils approved by Porsche only. This 
is a precondition for optimum and problem-free 
operation of your vehicle.
– Regular oil changes are part of servicing.
It is important that the service intervals, 
particularly the oil change intervals, are 
observed in accordance with the specifications 
in the “Maintenance” booklet.
– Oils approved by Porsche can be mixed with 
each other.
– Porsche engines are designed so that no oil 
additives may be used.
– A label is located in the engine compartment, 
which provides you with information on suitable 
oil for your engine.
Your Porsche partner will be pleased to advise 
you.
Oil changeThe engine oil has to be changed regularly at the 
intervals listed in your Maintenance Schedule. 
fPlease see the chapter “CAPACITIES” on 
Page 290.
We recommend that you have the engine oil 
changed at your Porsche dealer, who has the re-
quired oils and the necessary filling equipment. 
If you suspect an oil leak in the engine have your 
dealer check it out immediately. 
All current engine oils are compatible with each 
other, i.e. when making an oil change it is not nec-
essary to flush the engine if you wish to use a dif-
ferent brand or grade of oil. 
Since, however, each brand of oil has a special 
composition, you should, if possible, use the 
same oil brand if it becomes necessary to top up 
between oil changes.
Porsche engines have long intervals between oil 
changes. You can make best use of these long oil 
change intervals by using multigrade oils since 
these are largely independent of seasonal fluctua-
tions in temperature.  Complies with 
approval

Maintenance, Car Care
Fuel Economy Fuel 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 at 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-
duces fuel economy. Always keep cargo to a 
minimum and remove all unnecessary items. 
fOrganize your trips to take in several errands 
in one trip. 
fAll electrical accessories contribute to in-
creased 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 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 observe all local and national speed 
limits. 
Operating your Porsche in other 
Countries Government 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 se-
rious damage to both engine and catalytic con-
verters could result; 
– se rvice  ma y be  inade qua te  due to  lack of prop-
er service facilities, tools or diagnostic equip-
ment; 
– 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 ship-
ping and forwarding requirements, as well as cur-
rent 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 vapors.
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. 
fPlease see the chapter “FUEL ECONOMY” on 
Page 214.
Please see the chapter “EMISSION CONTROL 
SYSTEM” on Page 218.
Please see the chapter “LEVEL GAGE” on 
Page 122.
Check engine warning light 
If the warning lights in the instrument panel and on-
board computer come on and remain on while 
driving, it suggests: 
– a potential engine control problem and the 
need for system service or
– an improperly fastened tank cap or – refueling with engine running. 
Opening the filler flapThe filler opening is under the filler flap in the front 
right fender. 
fWith the vehicle unlocked, press on the front 
part of the filler flap (arrow) to open the flap. 
The filler flap is centrally locked along with the oth-
er locks. If there is a defect in the automatic unlocking 
system: 
fOpen the passenger door. 
fPull the ring in the right-hand door aperture 
(arrow).

Maintenance, Car Care
Refueling Fuel tank capacity is listed under “Capacities”.
Porsche does not recommend the use of fuel ad-
ditives.
Fuel is highly flammable and harmful to 
health.
fPlease see the chapter “CAPACITIES” on 
Page 290.1.Important: Stop the engine and switch off the 
ignition. 
2. Slowly unscrew the tank cap.
Hang the tank cap's plastic strap on the hook 
on the inside wall of  the filler flap. 
3. Insert fuel-hose nozzle fully into the filler neck 
with the handle of the fuel-hose nozzle facing 
down. 
4. Do not add further fuel once the correctly op-
erated automatic fuel-hose nozzle has 
switched off.
Fuel could spray or could run over in warm 
temperatures. 
5. Replace the tank cap immediately after 
refueling and turn it until you hear it and feel it 
engage. 
If you lose the tank cap, you must replace it 
only with an original part to reduce the 
possibility of a fire in the event of a collision.
 Caution!
Risk of damage. Decorative film may fade if 
it comes into contact with fuel.
fWipe off any emerging fuel immediately.
Fuel Recommendations Your Porsche is equipped with catalytic convert-
ers and must use UNLEADED FUEL ONLY. 
Your engine is designed to provide optimum per-
formance and fuel economy using unleaded premi-
um fuel with an octane rating of 98 RON 
(93
CLC or AKI). Porsche therefore recom-
mends 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 tim-
ing, if necessary. 
It is important to observe the regular service inter-
vals, and particularly the oil change intervals, 
specified in the “Maintenance” booklet.
The use of UNLEADED FUEL ONLY is critically 
important to the life of the catalytic 
converters. Deposits from leaded fuels will 
ruin the converters and make it ineffective 
as an emission control device. 
Cars with catalytic converters have a smaller fuel 
tank opening, and gas station pumps have smaller 
nozzles. This will prevent accidental pumping of 
leaded fuel into cars with catalytic converters.

Maintenance, Car Care
Emission Control SystemIn the interest of clean air Pollution of our environment has become a prob-
lem 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 sys-
tem 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 
responsibility to provide regular maintenance serv-
ice for the vehicle and to keep a record of all main-
tenance work performed. To facilitate record 
keeping, have the service performed by author-
ized 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 de-
scribed in your Maintenance Booklet. 
Lack of proper maintenance, as well as im-
proper use of the vehicle, will impair the func-
tion 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 vehi-
cle’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 operat-
ing conditions. 
Parking 
 Warning!
Danger of fire resulting in serious personal 
injury or death. 
fDo not park or operate the vehicle in areas 
where the hot exhaust system may come in 
contact with dry grass, brush, fuel spill or oth-
er flammable material. 
fIf your car catches on fire for any reason, call 
the fire department. 
Do not endanger your life by attempting to put out the fire. 
Undercoating 
 Danger!
Danger of fire resulting in serious personal 
injury or death.
fDo not apply additional undercoating or rust-
proofing on or near the exhaust manifold, 
exhaust pipes, catalytic converters or heat 
shields. During driving the substance used for undercoating could overheat and ignite.

Maintenance, Car Care
Air Filter A dirty air filter not only reduces engine perform-
ance, but can lead to premature engine wear. 
Regular filter replacement is part of the routine 
maintenance service. 
fIn dusty conditions, check the filter element 
more frequently and replace if necessary.Combination Filter The fresh air passing through the combination fil-
ter into the passenger compartment is virtually 
free of dust, pollen, and unpleasant odors. 
fIf the outside air is polluted by exhaust fumes, 
press the circulating-air button.
A dirty filter can be the cause of reduced air flow: 
fHave filter replaced by your authorized 
Porsche dealer.
Regular filter replacement is part of the routine 
maintenance service.
Fluids/Oils for Manual 
Transmission and Porsche 
Doppelkupplung (PDK)The transmission fluids/oils have to be checked 
and changed at the intervals listed in your Mainte-
nance Schedule. 
fPlease see the chapter “CAPACITIES” on 
Page 290.
Do not tow the car or run the engine without fluid/
oil in the transmission. The transmission may be 
damaged by even a tiny speck of dirt, only a clean 
funnel or spout must be used when adding fluid/
oil. 
We recommend that you have the fluids/oils 
changed at your Porsche dealer, who has the re-
quired lubricants and the necessary filling equip-
ment. 
fIf you suspect an oil leak in the transmission, 
have your authorized Porsche dealer check it 
out immediately.

Practical Tips, Emergency Service
Exercise Extreme Caution when 
Working on your Vehicle 
 Danger!
Ignoring the following instructions may 
cause 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 also 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 cau-
tious of such devices such as hot water heat-
ers which ignite a flame intermittently. 
fBefore working on any part in the engine com-
partment, 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 work has to be performed with the engine 
running, always set the parking brake, and 
make sure the shift lever is in neutral position 
or the PDK selector lever in position P or N.fIn particular, be very careful to ensure that 
items of clothing (ties, shirt, sleeves etc.), jew-
elry, long hair, hand or fingers cannot get 
caught in the engine-compartment blower, fan, 
belts or other moving parts.
The radiator and radiator fans are in the front 
of the car.
The engine-compartment blower is mounted 
on the engine-compartment lid.
The engine-compartment blower 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 en-
gine off, the ignition switched off, and exercise 
extreme caution.
fYour Porsche is equipped with an electronic ig-
nition system. When the ignition is on, high volt-
age 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.
Jacks are not suitable for this kind of work.
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 
cannot be started.
Remove the ignition key.fDo not smoke or allow an open flame around 
the battery or fuel.
Keep a fire extinguisher in close reach. 
fIncomplete or improper servicing may cause 
problems in the operation of the car. If in doubt 
about any servicing, have it done by your au-
thorized Porsche dealer.
Improper maintenance during the warranty pe-
riod may affect your Porsche warranty cover-
age. 
fSupplies of fluids, e.g. engine oil, 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. 
Please make enquiries before driving abroad.
