Operation of the ABS system A wheel speed sensor is mounted to each of the
four wheels. If wheel lock-up of either of the front
wheels or the rear wheels is sensed during brak-
ing, the brake pressure is adjusted automatically
until the wheel no longer slips. The brake pressure
is regulated for each front wheel individually and
for both of the rear wheels together.
On a road surface which is slippery on only one
side, the rear wheel which is braking on the slip-
pery surface determines the brake pressure which
will be applied equally to both rear wheels. This en-
sures that directional stability is maintained. How-
ever, if braking forces approach the wheel lock-up
point for all wheels (panic braking) the ABS system
will intervene to provide a rapid rhythmic braking.
The proper operation of ABS is perceived by the
driver as a pulsating brake pedal in conjunction
with audible noise and perhaps some vibration.
fIf you experience these sensations while driv-
ing or a road surface with questionable trac-
tion, reduce vehicle speed appropriate for the
prevailing road conditions.
The functional readiness of all the main electrical
components of the ABS is checked by an electron-
ic monitoring system both before and while you
drive. When the ignition is switched on the ABS warning
light will light up while the system is electronically
interrogated and goes out when the engine is
started if the check is not yet complete.
If the ABS warning lamp fails to go out, this indi-
cates that ABS has been deactivated due to a
fault. If the warning lights in the instrument panel
and on-board computer light up while you are driv-
ing, this indicates that a fault has occurred. In both
cases, normal braking, as in vehicles without ABS,
is still retained.
The ABS system should, however, be examined at
an authorized Porsche dealer immediately to pre-
vent the occurrence of further faults.
fIf the ABS system becomes inoperative, take
your vehicle to your authorized Porsche dealer
immediately.
Warning!
The control unit of the ABS brake system is
set for standard tire size. If non-standard
tires are installed, the control unit may mis-
interpret the speed of the vehicle, because of
the variant data it receives from the sensors
on the axles.
fUse only tire makes and types tested by Porsche.

Porsche Stability Management
(PSM)PSM is an active control system for stabilization of
the vehicle during extreme driving maneuvers.
Warning!
The increased control that is provided should
not induce you to take greater risks with your
safety. The limits dictated by the laws of
physics cannot be overcome, even with PSM.
The risk of accidents due to inappropriate
speed cannot be reduced, even by PSM.
The driver bears the responsibility for all
driving maneuvers.
fAdapt your driving style to the prevailing road
and weather conditions.
fObey all traffic laws. Advantages of PSM – Superior traction and lane-holding ability in all
driving situations – even on road surfaces with
varying friction.
– PSM actively stabilizes the vehicle during dy-
namic driving maneuvers (e.g. rapid steering
movements, during lane changes or on alter-
nating curves).
– Improved braking stability in curves and on dif-
ferent or varying road surfaces.
Readiness for operationPSM is switched on automatically every time you
start the engine. FunctionSensors at the wheels, brakes, steering system
and engine continuously measure:
– Speed
– Direction of travel (steering angle)
– Lateral acceleration
– Rate of turn about the vertical axis
PSM uses these values to determine the direction
of travel desired by the driver.
PSM intervenes and corrects the course if the
actual direction of motion deviates from the
desired course (steering-wheel position):
It brakes individual wheels as needed. In addition,
the engine power may be manipulated in order to
stabilize the vehicle. The events below inform the driver of PSM control
operations and warn him to adapt his driving style
to the road conditions:
– The multi-functional information light on the
instrument panel flashes.
– Hydraulic noises can be heard.
– The vehicle decelerates and steering-wheel
forces are altered as the PSM controls the
brakes.
– Reduced engine power.
– The brake pedal pulsates and its position is
changed during braking.
In order to achieve full vehicle deceleration,
foot pressure must be increased after the
brake pedal has begun pulsating.

Parking Aids Parking Assistant (ParkAssistant) When 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.
Danger!
Risk of serious personal injury or death.
ParkAssistant cannot detect small objects
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.
fMake sure that no persons, especially small
children, animals or obstacles are within the maneuvering area.
The parking assistant system is activated auto-
matically when reverse gear is selected and the ig-
nition is on.
Note
Be aware that the parking assistant system is not
switched on if the car rolls backward without re-
verse 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 dust, ice
and snow in order to ensure that they are fully
functional.
Caution!
To avoid damaging the sensors:
fMaintain sufficient distance when cleaning with steam-jet units.
Signal tones/function
When reverse gear is selected, the parking assist-
ant 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 be-
comes 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 not be so loud as to
drown out the signal tones.

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 authorized
Porsche dealer.
A - Control switch for door mirror adjustment Swivelling down mirror glass on the
passenger’s side On vehicles with seat memory you can activate an
additional parking aid.
fPlease observe the chapter “SEAT MEMORY”
on Page 34.
– When reverse gear is engaged, the mirror
glass on the passenger’s side swivels down
slightly to show the curb area. Preconditions
– Vehicle must be equipped with seat memory.
– Set the control switch A to “passenger’s side”.
– Reverse gear must be engaged.
Returning mirror glass to its original position
fDrive forwards with a speed of over 4 mph
(6 km/h) or
– Set the control switch A to “driver’s side”.

Warning!
Serious personal injury or death may result if
you are involved in a collision without having
fastened the safety belts.
fFasten safety belts before driving away. Before starting the engine fApply the handbrake.
fManual transmission:
Move the gearshift lever into neutral.
The clutch pedal must be depressed fully
before the starter will engage.
fTiptronic:
Move the selector lever to 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 enginefTurn ignition key to ignition lock position 2.
fAs soon as the engine starts, 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:
fWait about 10 seconds before engaging the
starter again.
fWhen starting the engine, be ready to drive im-
mediately.
Drive vehicle at moderate speeds and avoid
engine speeds above 4,200 rpm during the
first 5 minutes.
fDo 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.
fNever start or let the engine run in an en-
closed, unventilated area.
It is not recommended to sit in your car for pro-
longed periods with the engine on and the car
not moving.
An unattended vehicle with a running engine
is potentially hazardous.
If warning lights should come on to indicate
improper operation, they would go unno-
ticed.
fNever leave the engine idling unattended.
Danger of fire.
fDo 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.
fIf your car catches on fire for any reason, call
the fire department.
Do not endanger your life by attempting to put out the fire.
