Shifting Gears
181
“Sport Plus” mode activated:
In “Sport Plus” mode, the PDK transmission
changes to a shift program designed for driving
on race circuits. 7th gear is not selected.
The gear-changing performance is enhanced
significantly again compared with “Sport” mode.
fPlease see the chapter “SPORT MODE” on
Page 61.
Driving with Launch Control
Driving with Launch Control allows you to achieve
maximum acceleration from a standing start. It is
intended to provide you with a unique enjoyment of
your vehicle under controlled circumstances and
is not intended to be used in any location where it
could be a nuisance to other persons.
Warning!
There is a risk of endangering other road
users if you use this Control in an improper
location or in a situation where other persons
might need to take evas ive action due to the
rapid acceleration that this technology
permits.
f Launch Control is designed to be used in a
controlled environment on closed circuit
driving courses where no vehicle cross traffic
or pedestrian traffic is present.
f Use Launch Control only if conditions permit it
to be applied in a safe manner. f
Do not use Launch Control if there is a possibi-
lity it could endanger other persons. Such a
possibility exists if you cannot see that you
have a clear road with no possibility of cross
traffic in your intended direction of driving. Caution!
Stress on components increases dramatically
when starting with maximum acceleration in
comparison with normal driving off. Use of
Launch Control will inevitably reduce the life
of the engaged engine and transmission
components.
Preconditions:
– Launch Control should only be used when the engine has reached operating temperature.
– “Sport Plus” mode must be switched on (light- emitting diode in button is on and “SPORT
PLUS” is displayed on the on-board computer).
1. Press the brake with your left foot.
2. Quickly press down the accelerator fully (kickdown activated) and hold.
The engine speed will flatten out at around
6500 rpm.
“Launch Control active” is displayed on the
on-board computer. 3. Release the brake within a few seconds.
Remaining stationary for a long time with
“Launch Control active” can lead to overload-
ing of the transmission.
In order to protect the transmission, the engine
power is then reduced an d the “Launch Control
active” process is cancelled.
Shifting gears on the steering wheel
With the shift buttons on the steering wheel, you
can change temporarily fr om automatic selection
mode D to manual mode M.
For example:
– Shifting down before bends and on entering built-up areas.
– Shifting down on downward slopes (engine braking).
– Shifting down for brief spurts of acceleration.
Manual selection mode remains engaged:
– for cornering (depending on the lateral acceler- ation) and overrunning,
– when the vehicle is stationary (e.g. at a junction).
The system leaves manual selection mode:
– automatically after approx. 8 seconds (unless cornering or overrunning),
– after driving off.

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 186.
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 271.
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.

Practical Tips, Emergency Service
241
Winter operation The capacity and ability of the battery to store
power decreases at low outside temperatures.
Moreover, the battery is more heavily loaded in
winter months, e.g. by the heated rear window,
more frequent use of additional lights, the fans
and the windshield wipers, etc.
f Have the battery checked before the start
of winter.
Maintenance note
Keep the battery well charged to prevent it
from freezing.
A discharged battery can freeze at 23 °F (--5 °C),
but a fully charged battery only freezes at -- 40 °F
(--40 °C).
A frozen battery must always be thawed before
connecting jump leads.
Replacing battery The service life of the batt ery is subject to normal
wear; it depends greatly on care, climatic condi-
tions, and driving conditions (distances, loads).
f Only use an original Porsche battery, with the
correct part number, as a replacement.
f Please observe the disposal instructions for
batteries.
Putting vehicle into operationAfter the battery is co nnected or after an exhaus-
tively discharged battery is charged, the multi-
functional PSM light lights up on the instrument
panel and a message appears on the on-board
computer to indicate a fault.
This fault can be remedied with a few simple
steps:
1. Start the engine.
2. With the vehicle stationary, perform a few steering movements to the left and right and
then drive a short distance in a straight line
until the multifunctinal PSM light goes out and
the message on the on-board computer
disappears.
3. If the warnings do not disappear, then:
Drive carefully to the nearest authorized
Porsche dealer.
Have the fault remedied.
4. After the warnings disappear: Stop the vehicle in a suitable place.
f Perform adaptation of the power windows:
Please see the chapter “STORING END
POSITION OF THE WINDOWS” on Page 28.

Fuel tank Refill volume approx. 16.9 U.S. gallons/64 liters, including approx. 2.6 U.S.gallons/10 liters reserve.
Fuel quality 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 tha t 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.
