Limits of ultrasonic measurement
The parking assistant system cannot detect:
– sound-absorbing obstacles (e.g. powder snow),
– sound-reflecting obstacles (e.g. glass surfac- es, flat painted surfaces)
– and very thin obstacles.
– Other ultrasound sources (e.g. pneumatic brakes of other vehicles, jackhammers) can
interfere with detection of obstacles.
Fault indication
The parking assistant system indicates a fault in
two ways:
– After reverse gear has been selected, the short signal tone is followed by a continuous
tone of the same pitch:
This indicates that sensors are soiled or cov-
ered with ice.
– After reverse gear has been selected, the short signal tone is followed by a continuous
tone with a much lower pitch:
This indicates a general system fault.
Please have the fault remedied at an author-
ized Porsche dealer. A

Operation, Safety
Stopping Engine fTurn key back to position 3.
f Do not stop engine immediately after hard or
extended driving.
Keep engine running at increased idle for
about two minutes to prevent excessive heat
build-up before turning off engine.
f To avoid discharging the battery, always re-
move the ignition key from the ignition lock.
f When leaving the car, always remove the igni-
tion key, apply the parking brake and engage
1st gear or reverse gear on vehicles with man-
ual transmission or move the selector lever to
position P on vehicles with PDK transmission.
f Engage the steering lock by moving the steer-
ing wheel to the left or right.
Turn the steering wheel to the locking position
before you switch off the engine so that you
don’t have to exert your self when locking or
unlocking the steering.
Warning!
Danger of injury. Hot engine compartment
components can burn skin on contact.
f Before working on any part in the engine
compartment, turn the engine off and let it cool
down sufficiently. Risk of burn injury when standing near or
coming into contact with the exhaust pipe.
The exhaust pipe is hot wh
en the vehicle is running
and remains hot for some time after the vehicle is
turned off.
f To prevent injury, make a point of noting where
your vehicle’s exhaust pipe is, avoid placing
your legs near the exhaust pipe, and closely
supervise children around the vehicle when the
exhaust pipe could be hot.
A hot exhaust pipe can cause serious burns.
Engine-compartment blower,
radiator fan The radiator and radiator fans are in the front of
the car.
The engine-compartment bl ower is mounted in the
engine compartment.
Warning!
Risk of injury.
After the engine is switched off, the engine-
compartment temperature is monitored for
approx. 30 minutes.
During this period, and depending on tem-
perature, the engine-compartment blower
may continue to run or start to run.
f Carry out work in these areas only with the en-
gine off, the ignition off, and exercise extreme
caution. Risk of injury. The radiator fans in the front
end of the car may be operating or
unexpectedly start operating when the
engine is switched on.
f
Carry out work in these areas only with the en-
gine switched off.
Automatic garage door The ignition system in your Porsche may interfere
with your electronically operated garage door.
fTo check this, drive your Porsche close to the
garage door. Make sure not to interfere with
the operating range of the door.
f Run the engine at different speeds.
f If the garage door opens or closes without you
operating the garage door unit in your car,
contact the dealer who installed the automatic
garage door to have the frequency and/or
coding of the garage door signal changed or
modified.

Drive-Off AssistantThe Drive-Off Assistant assists the driver when
moving off on hills.
The vehicle must have sufficient road contact.
The Drive-Off Assistant is available on gradients as
from around 5%.
Danger!
Risk of accident.
Assistance by the Drive-Off Assistant is not
guaranteed when moving off on a slippery
surface (e.g. on icy or loose surfaces). In this
case, the vehicle could slip.
The limits dictated by the laws of physics
cannot be overcome, even with the Drive-Off
Assistant. The responsi bility for moving off
on upward slopes is still the driver’s, despite
the Drive-Off Assistant.
f Always adjust your driving style to the driving
conditions and vehicle load, use the brake
pedal if necessary.
Risk of accident.
If the Drive-Off Assistant is not functioning,
the driver cannot be assisted when moving
off on hills.
f Hold the vehicle with the brake pedal. Driving off with the Drive-Off Assistant
(vehicles with manual transmission)
1. Hold the vehicle secure
ly on the slope with the
brake pedal.
The engine must be running.
2. Fully depress the clutch pedal.
3. Engage a gear corresponding to the direction of travel up the slope (1st gear or reverse
gear).
4. Fully release the parking brake.
5. While keeping the clutch pedal depressed, release the brake pedal.
The vehicle is held on the slope for a short time
in order to allow driving off directly after the
brake is released.
6. Move off as usual.
Note on operation
The Drive-Off Assistant is not active:
– If the clutch is not depressed.
– If the vehicle is not stationary.
– If the engine is not running.
– On gradients of less than 5%.
– If the pressure on the brake pedal is too low. Driving off with the Drive-Off Assistant
(vehicles with PDK transmission)
1. Hold the vehicle securely on the slope with the
brake pedal.
The engine must be running.
2. Select a gear corresponding to the direction of travel up the slope (selector lever position
Dor R).
3. Fully release the parking brake.
4. Release the brake pedal. The vehicle is held on the slope for a short time
in order to allow driving off directly after the
brake is released.
5. Move off as usual.
Note on operation
The Drive-Off Assistant is not active:
– In the event of shift to neutral.
– If the vehicle is not stationary.
– If the engine is not running.
– On gradients of less than 5%.
– If the pressure on the brake pedal is too low.

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
183
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 259.
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
