Porsche Doppelkupplung (PDK)Porsche Doppelkupplung (PDK) is a seven-speed
transmission with an “automatic” and a “manual”
selection mode.
In automatic selection mode (selector-lever
position D), gear changing is automatic.
You can change temporarily from automatic to
manual mode using the shift buttons on the
steering wheel.
In manual selection mode (selector-lever
position M ), you change gear using the shift
buttons on the steering wheel or with the PDK
selector lever.
You can change between selector-lever
positions D and M as you wish while driving.
Note
f Take care not to operate the shift buttons on
the steering wheel in advertently in either
automatic or manual mode, thereby triggering
undesired gear changes.
Changing the selector-lever positionThe selector lever is blocked when the ignition is
switched off.
When the ignition is switch ed on, the selector lever
can be moved from position P and N only when
the release button is pressed, and when the brake
pedal is pressed.
Release button
The release button ( arrow) in the selector lever
prevents the gear from being changed
unintentionally.
The release button must be pressed when shifting
to position R or P.
StartingThe engine can only be started using the car key
if the brake pedal is pressed and the selector lever
is in position P or N.Driving offf Only select the desired position for driving off
(D, M or R) when the engine is idling and the
brake pedal is pressed.
f Since the vehicle crawls when in gear,
do not release the brake until you are ready
to drive off.
Driving off on hills
The Drive-Off Assistant assists the driver when
driving off on hills. The vehicle is held on the slope
when the driver changes from the brake pedal to
the accelerator to facilitate driving off immediately
after the brake is released.
f Please see the chapter “HOLD FUNCTION:
DRIVE-OFF ASSISTANT AND STANDSTILL
MANAGEMENT” on page 206.

– The corresponding selector-lever position on the instrument panel flashes and the warning
“Press brake” or “Selector not engaged”
appears on the multi-function display. Action required:
f
Operate the footbrake and engage the
selector lever properly.
If the selector lever is inadvertently changed
from P or N into a gear (due to a fault or improper
use) without pressing the brake, this gear will also
"flash" on the display and no power transmission
will occur. 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 flashes in the
instrument panel
Effects:
– No power transmission occurs. The selector lever was engaged without
pressing the footbrake or only the reduced
driving program is available when the message
“Gearbox emergency operation” appears.
Action required:
f Press the footbrake and engage the required
selector-lever position again from P or N.

Selector-Lever PositionsP – Parking lockfEngage parking lock only when the vehicle is
stationary.
If selector-lever position P is flashing in the
instrument panel, the parking lock is not
engaged. The vehicle can roll away.
Shift again from selector-lever position R to P.
f Activate the electric parking brake and then
engage the parking lock.
If selector-lever position P is flashing in the
instrument panel, the parking lock is not
engaged. The vehicle can roll away.
Shift again from selector-lever position R to P.
The ignition key can be removed only in selector-
lever position P.R – Reverse gearf Select only if the vehicl e is stationary and the
brake is applied.N – Neutral (idling)Selector-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 pressed.
D – Automatic selection modeSelect position D for “normal” driving. The gears
are shifted automatically according to the
accelerator 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 upshifts, e.g. when entering
bends, are prevented by swiftly releasing the
accelerator pedal.
Depending on lateral acceleration, upshifts on
bends are not made until the engine-speed limit
is reached.
When you brake, 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 accelerate 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 points, if the accelerator
pedal is pressed quickly. The transmission
accordingly shifts down
immediately by one or
two gears (temporary change-down).
The transmission no longer selects 7th gear
at high driving speeds.
“Sport” and “Sport Plus” Mode “Sport” mode activated:
The PDK transmission switches to a sporty gear-
changing map and shortens the shifting times.
A sporty driving style is recognized more quickly
and the gear-changing speeds are adapted to
driving performance.
Deceleration downshifts are initiated earlier.
Downshifts occur for small decelerations,
even at higher revs.
“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.
f Please see the chapter ““SPORT” AND “SPORT
PLUS” MODE” on page 212.
