Windshield Wiper / Washer Lever
Warning!
Danger of injury when the windshield wipers
operate unintentionally, e.g. in intermittent
or rain sensor operation.
Risk of damage to the windshield and wiper
system.
fAvoid running the wiper blades over a dry wind-
shield to prevent scratching the glass. Spray
washer fluid on the windshield first.
A scratched windshield will reduce visibility.
fAlways loosen wiper blades from frozen glass
before operating wipers to prevent damage to
the wiper motor or blades. fAlways switch off windshield wipers in car
wash to prevent them wiping unintentionally
(intermittent or sensor operation).
fAlways switch off windshield wipers before
cleaning the windshield to avoid unintentional
operation (intermittent or sensor operation).
fDo not operate the headlight washer in car
washes.
fDo not operate headlight washer when it is
frozen.

shield wipers wipe once.5 – Windshield wipers and washer system:
fPull wiper lever towards the steering wheel.
The washer system sprays and wipes while the
lever is pulled towards the steering wheel.
When the wiper lever is released, a few drying
wipes are executed.
A - Headlight washer:
The washer sprays only while low beam or high
beam is switched on.
fBriefly push button A to operate headlight
washer system.

Decelerating Option 1
fPull operating lever towards the steering wheel
(position 2) until the desired speed is reached.
The speed reached is maintained and stored
when the lever is released.
Option 2
fBriefly move lever towards the steering wheel
(position 2) (a maximum of 10 times).
The speed is reduced by 1 mph (1.6 km/h),
each time the lever is moved towards the
steering wheel.
Vehicles with PDK
Downshifts are carried out to improve decelera-
tion (especially when driving downhill).
Interrupting automatic speed control
operation fPull operating lever downwards briefly
(position 3) or
fOperate brake or clutch pedal or
fSwitch PDK to selector lever position N.
fPlease see the chapter “PORSCHE DOPPEL-
KUPPLUNG (PDK)” on Page 170.
The speed driven before the interruption remains
stored in the memory.
Automatic speed control operation is
interrupted automatically:
– If the set vehicle speed is exceeded by more
than approx. 16 mph (25 km/h) for longer than
20 seconds.
– If the actual vehicle speed falls to approx.
37 mph (60 km/h) below the set vehicle speed
for longer than 60 seconds (upward slopes).
– For PSM control operations.
Resuming the stored speed fBriefly push operating lever upwards
(position4).
The speed control accelerates/decelerates
the vehicle to the stored speed.
The stored speed should only be recalled when
traffic conditions and the road surface so permit.Switching automatic speed control
readiness off fPress button A on the automatic speed control
lever.
The green readiness light in the speedometer
goes off.
Note
The stored speed value is cleared when the
vehicle is parked and the ignition is switched off.
Important note
On upward or downward slopes, the set speed
cannot always be maintained by the automatic
speed control.
fTo obtain sufficient engine braking or a better
engine-speed range, a lower gear needs to be
selected.

Operate the footbrake and engage the
selector lever properly.
If 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
fEffects:
Restricted gearshift comfort,
Failure of reverse gear.
Remedy:
Have the fault repaired immediately at an
authorized Porsche dealer.Warning “Transmission emergency run” red
– Effect:

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.
Warning “Transmission temperature too high”
–Effects:
“Warning jerks” can be felt when driving off and
the engine power may be restricted.
Remedies:
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.

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 lock is not
engaged. The vehicle can roll away.
Engage selector lever position P again by
moving the selector lever out of R.
fEngage 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 gearfSelect 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.
fOnly 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 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 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
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.
