Indicator for selector lever position and
engaged gearWhen the engine is running, the selector lever
position and engaged gear are indicated.
If the selector lever is between two positions
–Effects: The corresponding selector-lever position in
the instrument panel flashes and the warning
“Actuate brake” or “Selector lever not
engaged” appears on the on-board computer.
f Action required:
Operate the footbrake and engage the
selector lever properly. If the selector lever is inadvertently (due to
a defect or incorrect operation) moved out of P or
N into gear without pressing the brake, this gear
will start to “flash” and no power transmission is
built up. To drive off, press the brake and move
the selector lever from P
or N into the required
gear again.
Selector-lever position R or D is flashing in the
instrument cluster
f Effects:
There is no power transmission.
The selector lever was engaged without
pressing the footbrake or only the restricted
driving programme is available when the
“Transmission emergency run” message
is displayed.
Action required:
Press the footbrake and engage the required
selector-lever position again by moving the
selector lever from P or N.
If reverse gear fails:
Please see the chapter “REDUCED DRIVING
PROGRAM” on Page 180. If there is a fault in the transmission:
– The warning “Transmission emergency run” in
white or red lettering or the warning “Transmis-
sion temperature too high” is displayed on the
on-board computer.
Please see the chapter “REDUCED DRIVING
PROGRAM” on Page 180.
f Have the fault repaired immediately at an
authorized Porsche dealer.

Shifting Gears
Selector lever positionsP – Parking lockfEngage parking lock only when vehicle is
stationary.
If selector-lever position P is flashing in the
instrument cluster, the parking brake is not
engaged. The vehicle can roll away.
Engage selector-lever position P again by
moving the selector lever out of R.
f Engage parking lock after applying the
handbrake and release it before releasing the
handbrake.
The ignition key can be withdrawn only in
selector lever position P.R – Reverse gearf Select only if car is stationary and the brake is
applied.N – NeutralSelector lever position N must be selected for
towing or in car washes, for example.
f Only select the desired position for driving off
(D, M or R) when the engine is idling and the
brake pedal is depressed.
D - Automatic selection modeSelect position D for “normal” driving. The gears
are shifted automatically according to the acceler-
ator position and speed.
Depending on the way the vehicle is driven
(economical, comfortable or sporty driving style)
and on the resistance (e.g. uphill), the gear-
changing points are shifted towards higher or
lower engine-speed ranges.
The accelerator position, driving speed, engine
speed, longitudinal and lateral acceleration and
the road profile all have an influence on the gear-
changing characteristic.
Unwanted upward shifts, e.g. before bends, are
prevented by swiftly releasing the accelerator
pedal.
Depending on lateral acceleration, upward
changes on bends are not made until the engine-
speed limit is reached.
Under braking, and depending on the amount of
deceleration, the PDK transmission changes down
earlier.
For subsequent cornering, the right gear is
engaged when pressure is applied to the brakes
before the bend. The bend is taken in the right
gear, and when you accelera te out of the bend you
do not have to change down. With a sporty driving style, downshifts are already
initiated when the brake pedal is touched lightly.
This further enhances
a dynamic driving style.
The PDK transmission temporarily changes to the
sportiest gear-changing map, i.e. to the highest
possible gear-changing poin ts, if the accelerator
pedal is pressed quickly. The transmission accord-
ingly shifts down immediately by one or two gears
(temporary change-down).
The transmission no longer selects 7th gear at
high driving speeds.
Sport mode
(“Sport” and “Sport Plus” modes)
“Sport” mode activated:
The PDK transmission switches to a sporty gear-
changing map and shortens the gear shifting
times.
A sporty driving style is recognised more quickly
and the gear-changing speeds are adapted to
driving performance.
Deceleration downshifts are commenced earlier.
Downshifts are already carried out in the case of
slight decelerations, even at higher engine
speeds.

Shifting Gears
179
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.
f Select 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 au tomatically at the upper
engine speed limit:
f Depress 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.
Please see the chapter “TOWING” on
Page 269.
Stoppingf For a brief stop (e.g. at a traffic light), leave the
selector lever in drive position and hold the
vehicle with the brake pedal.
f Do not hold the car on a slope using the
accelerator. Use the brake pedal or the
handbrake instead.
f Before leaving the vehicle, always apply the
handbrake and move the selector lever to
position P.Parkingf Go easy on the accelerator!
f When 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 mo de. This prevents gear
changes occurring that could cause wheelspin.Tow-starting, towingf Please see the chapter “TOWING” on
