“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 64.
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 evasive action due to the
rapid acceleration that this technology
permits.
fLaunch 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.
fUse Launch Control only if conditions permit it
to be applied in a safe manner. fDo 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 and 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 from 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.

174
Shifting Gears Kickdown
The kickdown function is active in selector lever
positions D and M.
fFor optimum acceleration, e.g. when
overtaking, depress the accelerator pedal
beyond the full-throttle point (kickdown).
The transmission shifts down depending on the
speed of travel and engine speed.
Upward shifts occur at the highest possible engine
speeds.
M – Manual selection modeThe currently selected gear is retained when you
change from D to M.
If you change from M to D, the gear-changing map
suitable for your current driving style is selected
and the appropriate gear is selected.
The selector lever and the two shift buttons in the
top steering wheel spokes allow you to comfort-
ably and reliably select the seven forward gears.Shifting up +
fPress the PDK selector lever or shift button on
the steering wheel forward.
Shifting down –
fPull the PDK selector lever or shift button on
the steering wheel back.
You can shift up or down by the corresponding
number of gears by quickly pressing or pulling the
shift buttons or selector lever several times in
succession.
The transmission can be shifted up or down by
several gears in succession by continuously
operating the selector lever or shift buttons.

Shifting Gears
175
Depending on driving speed and engine speed,
you can shift up or down at any time.
Gear changes which would exceed the upper or
lower engine speed limit are not executed by the
controller.
There is no automatic upshift at the upper engine
speed limit in selector lever position M. Upshift
suppression can be cancelled by kickdown opera-
tion. If, for example, the engine speed limit is
reached during overtaking and the automatic
upshift does not occur, the transmission in this
case shifts up as a result of kickdown operation.
fSelect an appropriately low gear on upward
and downward slopes.
This will ensure optimum use of engine power
and engine braking.
In order to shift up automatically at the upper
engine speed limit:
fDepress the accelerator pedal beyond the full-
throttle point (kickdown).Failure of the selector lever display on the
instrument cluster
The warning “Transmission emergency run” is
displayed in red on the on-board computer.
–Effect:
No selector lever position is displayed on the
instrument cluster.
Vehicle can be driven only until it comes to a
stop.
Remedy:
It is not possible to continue driving. Immedi-
ately stop the vehicle in a suitable place. Have
the vehicle towed to an authorized Porsche
dealer.
StoppingfFor a brief stop (e.g. at a traffic light), leave the
selector lever in drive position and hold the
vehicle with the brake pedal.
fDo not hold the car on a slope using the
accelerator. Use the brake pedal or the
handbrake instead.
fBefore leaving the vehicle, always apply the
handbrake and move the selector lever to
position P.ParkingfGo easy on the accelerator!
fWhen parking or manoeuvring in a small
space, control the speed by careful use of the
footbrake.Driving in winterIn wintry road conditions it is advisable to take
steep inclines in manual mode. This prevents gear
changes occurring that could cause wheelspin.Tow-starting, towingfPlease see the chapter “TOWING” on
Page 280.

Reduced driving programIf there is a fault in the transmission
– Depending on priority, the warning “Transmis-
sion emergency run” in white or red lettering or
the warning “Transmission temperature too
high” is displayed on the on-board computer.
Warning “Transmission emergency run” white
– Effects:
Restricted gearshift comfort,
Reverse gear may not function.
Remedy:

ately stop the vehicle in a suitable place. Have
the vehicle towed to an authorized Porsche
dealer.
Warning “Transmission temperature too high”
–Effects:
“Warning jerks” can be felt when driving off and
the engine power may be restricted.
Remedy:
Do not hold the vehicle with the accelerator on
a hill, for example. Hold the vehicle with the
brake. Reduce engine load. If possible, stop
the vehicle in a suitable place. Allow the engine
to run in selector lever position P or N until the
warning disappears.
