The variable suspension system selects the appro-
priate damping level for each wheel according to
the situation and driving conditions.
Example:
If the vehicle is driven in a very sporty manner in
Normal mode, PASM automatically adapts the
shock-absorber behavior to the driving situation
accordingly.

bility will be adversel y affected by increased
rear axle lift, which could lead to loss of con-
trol.

Operation, Safety
Parking Aids Parking assistantWhen the driver backs up, the parking assistant
system indicates the distance between the car
and a large obstacle behind it, by means of signal
tones.
Warning!
Risk of serious personal injury or death.
Parking assistant cannot detect small ob-
jects such as children and pets.
Despite use of the parking assistant system,
the driver is still responsible for taking due
care and assessing obstacles when backing
up.
f Make sure that no persons, especially small
children, animals or obstacles are within the maneuvering area.
The parking assistant syst em is activated auto-
matically when reverse gear is selected and the ig-
nition is on.
Note
Be aware that the parkin g assistant system is
not switched on if the car rolls backward without
reverse gear being engaged.
Ultrasound sensors Sensors
Four ultrasound sensors in the rear bumper meas-
ure the distance to the closest obstacle.
– Range middle sensors around 60 in./150 cm
– Range outer sensors around 24 in./60 cm
Obstacles cannot be detected in the “blind” sen-
sor area (e.g. near the ground). Note
The sensors must always be kept free of dirt, ice
and snow in order to ensure that they are fully
functional.
Caution!
To avoid damaging the sensors:
f Maintain sufficient distance when cleaning with steam-jet units.
Signal tones/function
When reverse gear is selected, the parking
assistant confirms that it is switched on by issuing
a short signal tone .
A detected obstacle is signalled by an intermit-
tent tone . The intervals decrease as the obstacle
is approached.
A continuous tone sounds when the distance
becomes less than one foot. This continuous tone
c a n s t o p i f t h e o b s t a c l e i s a p p ro a c h e d c l o s e r t h a n
one foot.
The radio volume should no t be so loud as to
drown out the signal tones.

Operation, Safety
71
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

shift lever into neutral.
The clutch pedal must be depressed fully
before the starter will engage.
f In vehicles with PDK transmission:
Move PDK selector lever to position P or N.
Temperature sensors on the engine automatically
provide the correct fuel/air mixture required for
starting.
Therefore, it is not necessary to depress the
accelerator pedal while starting a cold or a
warm engine.
Starting the enginef Turn ignition key to ignition lock position 2.
f As soon as the engine st arts, release the igni-
tion key.
The first operation of the starter is ended automat-
ically when the engine starts.
If the engine does not start, subsequent starter
operations will not be ended automatically.
If the engine fails to start after 10 or 15 seconds
of cranking:
f Wait about 10 seconds before engaging the
starter again.
f When starting the engine, be ready to drive
immediately.
Drive vehicle at moderate speeds and avoid
engine speeds above 4,200 rpm during the
first 5 minutes.
f Do not let the engine idle to warm up.
Danger!
Engine exhaust fumes have many compo-
nents which you can smell. They also contain
carbon monoxide (CO), which is a colorless
and odorless gas.
Carbon monoxide can cause unconscious-
ness and even death if inhaled.
f Never start or let the engine run in an
enclosed, unventilated area.
It is not recommended to sit in your car for prolonged periods with the engine on and the
car not moving.
An unattended vehicle with a running engine
is potentially hazardous.
If warning lights shoul d come on to indicate
improper operation, they would go unno-
ticed.
f Never leave the engine idling unattended.
Danger of fire.
f Do not park or operate the vehicle in areas
where the hot exhaust system may come in
contact with dry grass, brush, fuel spill or oth-
er flammable material.
f If your car catches on fire for any reason, call
the fire department.
Do not endanger your life by attempting to put
out the fire.
Risk of burn injury when standing near or
coming into contact with the exhaust pipe.
The exhaust pipe is hot when 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.
