Shifting Gear Manual mode failure
If manual mode fails, the control electronics
switch to automatic mode. In this event, the
instrument cluster will display selector lever
position D.
fHave the fault remedied.
Consult an authorized Porsche dealer.
Stopping fFor a brief stop, e.g. at a traffic light, leave the
selector lever in drive position and hold the ve-
hicle with the brake pedal.
fFor a longer stop with the engine running,
select position N (neutral).
fDo not hold the car on a slope using the
accelerator. Use the brake pedal or the hand-
brake instead.
fBefore leaving the vehicle, always apply the
handbrake and move the selector lever to
position P.
Parking fGo easy on the accelerator.
fWhen parking or maneuvering in a small
space, control the speed by careful use of the
footbrake. Driving in winter In wintery road conditions it is advisable to take
steep inclines in manual mode. This prevents the
occurrence of gear changes that could cause
wheelspin. Tow-starting, towing fPlease observe the chapter “TOWING” on Page
260.

Maintenance, Car Care
Air Filter The air filter is on the left-hand side of the engine
compartment.
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 filterThe fresh air passing through the combination
filter 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
throughput:
fHave the filter replaced by an authorized
Porsche dealer.
Regular filter replacement is part of servicing.
Automatic Transmission Fluid The torque converter and the transmission are lu-
bricated with Automatic Transmission Fluid (ATF).
The final drive requires transmission oil.
fPlease observe the chapter “CAPACITIES” on
Page 271.
Do not tow the car or run the engine without ATF
in the transmission. The automatic transmission
may be damaged by even a tiny speck of dirt, only
a clean funnel or spout must be used when adding
AT F.
The ATF and transmission oil has to be checked
and changed at the intervals listed in your Mainte-
nance Schedule.
We recommend that you have the ATF and trans-
mission oil changed at your Porsche dealer, who
has the required lubricants and the necessary fill-
ing equipment.
If you suspect an oil leak in the transmission, have
your authorized Porsche dealer check it out imme-
diately.
Manual Transmission Oil The transmission oil has to be checked and
changed at the intervals listed in your Maintenance
Schedule.
fPlease observe the chapter “CAPACITIES” on
Page 271.
We recommend that you have the transmission oil
changed at your Porsche dealer, who has the re-
quired lubricants and the necessary filling equip-
ment.
If you suspect an oil leak in the transmission, have
your authorized Porsche dealer check it out imme-
diately.

Maintenance, Car Care
Warning!
Danger of fire and serious personal injuries.
fDo not apply additional undercoating or rust-
proofing on or near the exhaust manifold, ex-
haust pipes, catalytic converters or heat
shields. During driving the substance used for undercoating could overheat and ignite.
fBefore applying fresh underseal, carefully re-
move deposits or dirt and grease. Once it has
dried, the new undercoating compound forms
a tough protective coating which provides effi-
cient rust-proofing of the floor panels and com-
ponents.
fAlways apply a fresh coating of suitable pre-
servative to unprotected areas after cleaning
the underside of the body, the transmission,
the engine or carrying out repairs to under-
body, engine or transmission components.
Effective rust-proofing is particularly important
during the cold weather season. If your car is driv-
en frequently in areas where salt has been spread
on the roads, the whole engine compartment
should be cleaned thoroughly after the winter to
prevent salt from causing any lasting damage. A
full under-body wash should also be performed at
the same time.
Door, lid and window seals fWash dirt (e.g. abrasion, dust, road salts) from
all seals regularly using warm soapy water. Do
not use any chemical cleaning agents or sol-
vents.
When there is a frost hazard, the outer door seals
and the front and rear lid seals can be protected
against freezing into place by a suitable care prod-
uct.
In order to prevent damage to the anti-fric-
tion coating, the inner door seals must not be
treated with care products. Stainless steel exhaust tailpipesStainless steel exhaust tailpipes can discolor due
to soiling, strong heat, and combustion residues.
The original polish can be achieved again using
commercially available metal polishing paste or
metal polish.
Headlights, lights, interior and exterior
plastic parts fUse only clean water and a little dishwashing
detergent to clean light lenses, plastic head-
light lenses, plastic parts and surfaces.
Do not clean when dry.
Use a soft sponge or a soft, lint-free cloth. Gen-
tly wipe the surface without applying too much
pressure.
The Porsche inside window cleaner is also suit-
able for cleaning plastic surfaces. Follow the
cleaning instructions on the container.
Never use other chemical cleaners or
solvents.
fRinse cleaned surfaces with clear water.

Fuel qualityYour 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 Octane™ knock control” will adapt the ignition timing, if necessary.
