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 281. 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 ca p 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.
f Wipe 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.

Power Steering 
 Warning!
Risk of accident resulti ng in serious personal 
injury or death. 
When the engine is stopped (e.g. when being 
towed) or the hydraulic system fails, there is 
no assistance for steering.
Therefore, substantially more force will have 
to be exerted in order to steer. 
f Exercise great care when being towed. 
f Have the fault remedied at your nearest autho-rized Porsche dealer. 
Note
The flow noise heard at full  steering lock is system 
related and does not indi cate a defect in the 
steering system. 
Checking hydraulic fluid f Please see the chapter “EXERCISE EXTREME 
CAUTION WHEN WORKING ON YOUR VEHICLE” 
on Page 196.
The hydraulic fluid reservoir is located in the engi-
ne compartment. 
Regular checking of hydraulic fluid is part of 
servicing.
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. 
f In 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 co mpartment is virtually 
free of dust, pollen, and unpleasant odors. 
f If the outside air is polluted by exhaust fumes, 
press the circulating-air button.
A dirty filter can be the cause of reduced air flow: 
f Have 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. 
f Please see the chapter “CAPACITIES” on 
Page 281.
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. 
f If you suspect an oil leak in the transmission, 
have your authorized Porsche dealer check it 
out immediately.

or death if the airbag system is impaired by 
improper cleaning work.
f Do not make any modifications whatsoever on 
individual components such as the padded 
covers of the steering  wheel, passenger side 
instrument panel, the front seats and the door 
linings.
f Let your authorized Porsche dealer clean these components.
Carpets and floor-mats fUse only a vacuum clea ner or a medium stiff 
brush. 
f Remove stains and spots with Porsche stain 
remover.
To protect carpets, the Porsche range of accesso-
ries includes mats of th e correct size and with the 
appropriate fastening.
 Warning!

sonal injury or death. 
f Always check the movement of the pedals be-
fore driving and make sure that they are not ob-
structed by a floor-ma t or any other object.  f
Secure the floor-mat to prevent it from sliding 
into positions that could interfere with the safe 
operation of your vehicl e - do not install them 
loosely in the vehicle.
Your Porsche dealer will be glad to offer you 
nonskid floor-mats of the correct size.
Cleaning fabric linings
f Fabric linings on pillars, convertible top liner 
and sun blinds, etc. must be cleaned only 
using suitable cleaning agents or a suitable dry 
foam and a soft brush.
Alcantara fDo not use a leather care product to clean 
Alcantara. 
For regular care it is su fficient to clean the cover 
with a soft brush.
Heavy abrasion or rubbing when cleaning causes 
a lasting change in the surface.
Cleaning when lightly soiled 
f Wet a soft cloth with water or a neutral soap 
solution and wipe off the dirt. 
Cleaning when heavily soiled 
f Wet a soft cloth with lukewarm water or 
thinned white spirit and dab the dirt from the

should be free of dirt and salt deposits. 
f Fill up the fuel tank. 
f Change the oil and oil filter, and run the engine 
for several minutes. 
f Increase the tire pressure to 50 psi (3.5 bar).
It is not recommended to lift the vehicle, due to 
the possibility of corros ion on shock absorber 
piston shafts.
The vehicle should be moved slightly, approxi-
mately every four weeks, to prevent flat spot 
on the tires. 
Climate control 
The air conditioning system should be in good 
working condition and fully charged. 
Windshield/Headlight washer 
f Check and correct antifr eeze/cleaning solution 
level as necessary.  Electrical system 
f

it in a cool dry place, not on a cement floor. 
When the battery is disconnected, the 
alarm system is deactivated. 
f Recharge the battery every 3 months. If the 
battery remains in the vehicle with the cables 
connected, it is necessary to check, remove 
and recharge the battery every 2-3 weeks. 
Do not fast charge the battery. 
f Please see the chapter “BATTERY” on 
Page 249.
Vehicle interior 
The interior must be dry,  especially in the area of 
the floor carpets. The use of drying agents (Silica-
Gel) is recommended in vehicles with leather inte-
rior and in areas with high humidity. The recom-
mended amount is 3 fabric bags of 1.1 lbs. 
(500 grams) each placed on the floor carpets. 
Windows, doors and lids must be closed. The air 
vents should be opened.

Practical Tips, Emergency Service
 Danger!
Risk of serious personal injury or death. 
Driving the vehicle with low tire pressure 
increases risk of a tire failure and resulting 
loss of control. Furthermore, low tire pres-
sure increases rate of wear of the affected 
tires.
f Check tires – including sidewalls – regularly for 
foreign bodies, nicks, cuts, cracks and bulges.
f After driving off road, examine tires for signs 
of damage such as cuts, tears, bulges or for-
eign objects stuck in the  tread. Replace a dam-
aged tire if necessary.
f Cross curb edges slowly and at right angles if 
possible. 
Avoid driving over steep or sharp curbs.
f In cases of doubt, have  the wheel (particularly 
the inner side) checked by an authorized Porsche dealer.
Tire replacements If in doubt, contact  your Porsche dealer.
Use only tire makes and types approved by 
Porsche. 
If you do not use a Porsche recommended 
replacement tire, make sure that you 
purchase your new tires from a reputable tire 
dealer and that the dealer complies with all 
manufacturers warnings for those tires. 
Only tires with the same make and with the 
same specification code (e.g. “N0”, “N1”...) 
can be mounted. 
Before mounting new tires, check with your 
Porsche dealer about the current release 
status. 
Use tires with “ZR” quality standards.  There 
are currently no standards concerning tire 
strength at speeds above 150 mph (240 km/h). 
Tires should be replaced no less than on one axle 
at the time. 
Only tires of the same make and type must be 
used. Mixed tires are not permissible. 
Initially, new tires do not  have their full traction. 
You should therefore drive at moderate speeds 
during the first 60 - 120 miles (100 - 200 km).  If new tires are installed only on one axle, a notice-
able change in handling occurs due to the different 
tread depth of the other tires. 
This happens especially if only rear tires are re-
placed. However, this condition disappears as the 
new tires are broken in. 
f
Please adjust your driving style accordingly.
Installation of new tires sh ould only be done by a 
qualified tire technician. 
Valves 
Rubber valve stems must be replaced every time 
a tire is replaced.
For metal valves, the installation and replacement 
instructions must be observed.
f Use only genuine Porsche metal valves.
f Protect the valve inserts against soiling with 
valve caps.
Soiled valve inserts can cause a gradual loss 
of air.
f Use only plastic valve caps.

Practical Tips, Emergency Service
A- Filler bottle
B - Filler hoseTire sealantThe tire sealant can be used to seal small cuts, 
especially in the tire tread.
Sealing the tire with the tire sealant is only an 
emergency repair, so you  can drive to the next 
workshop. Even with the tire  air-tight, it may be 
used only for short journeys in an emergency. The tire sealant and a compressor with pressure 
tester can be found in the luggage compartment.
The tire sealant comprises: 
– A filler bottle
– A sticker denoting the maximum permissible 
speed for the driver’s field of vision
– A filler hose
– A valve turner and
– A spare valve insert.
 Danger!
Risk of accident , resulting in serious per-
sonal injury or death.
f Use the tire sealant only in the case of cuts or 
punctures no larger than 0.15 in. (4 mm).
f Never use the tire sealant if the rim is dam-aged.
 Warning!
The sealant is highly flammable and harmful 
to health.
f Fire, naked flame and smoking are prohibited 
when handling tire sealant.
f Avoid contact with skin, ey es or clothing due to 
caustic chemical properties of the tire sealant.
f Keep tire sealant away from children.
f Do not inhale vapors, due to consequent harm 
to personal health  resulting in serious personal injury or death.
In case of contact with the sealant:
f If sealant gets on the skin or in the eyes, 
thoroughly rinse the affect ed part of the body 
off immediately.
f Change soiled clothing immediately.
f Get medical attention immediately in the event 
of an allergic reaction.
f If sealant was swallowed, thoroughly rinse out 
the mouth without delay an d drink plenty of 
water.
Do not induce vomiting.
Get medical attention immediately.
