Airbag Systems The ”Airbags“ in combination with the safety belts
makes up a safety system which offers the driver
and the passenger the greatest known protection
from injuries in case of an accident.
Even if your vehicle is equipped with airbags, the
safety belts are your primary protection and
must be worn at all times.
The airbags can only help protect you where the
impact is of sufficient severity and from a speci-
fied direction.
Therefore, all persons within the vehicle
must always wear safety belts (in many states,
state law requires the use of safety belts).
fPlease observe the chapter “SAFETY BELTS”
on Page 42.
The front airbags are located behind the padded
steering wheel panel on the driver’s side and on
the passenger’s side in the dashboard.
The side airbags are installed in the side of the
seat backrests.
The head airbags are installed in the door linings.
Function Depending on the force and angle of impact, the
corresponding airbags can be triggered.
The inflation process generates the amount of gas
required to fill the airbags at the necessary pres-
sure in fractions of a second. Because of the pos-
sibility of injuries from airbag deployment, airbags
are designed to deploy only when occupants
would receive substantial additional injuries if the
airbags did not deploy.
Airbags protect the face and upper body, while si-
multaneously damping the motion of the driver
and passenger in the impact direction in the event
of a frontal impact or side impact.
Your vehicle is equipped with a crash sensing and
diagnostic module. This module will record the
use of the safety belt restraint system by the driv-
er and front passenger when the side airbags and
head airbags are inflated.
Danger!
To provide optimal occupant protection, air-
bags must inflate at very high speed.
If you are not wearing your safety belt or are
too close to the airbag when its deployed, in-
flating airbags can result in serious personal
injury or death.
fMake sure there are no people, animals or ob-
jects between the driver or passenger and the
area into which the airbag inflates.
fSit back as far from the dashboard or steering
wheel as is practical, while still maintaining full
vehicle control.
fDo not lean against the inside of the doors.
fAlways leave feet in the footwell when driving.
Do not put feet on the dashboard or the seat
cushion.
fAlways hold the steering wheel by the outer
rim.
Never rest your hands on the airbag panel.
fNever transport heavy or sharp objects on or
in front of the passenger seat.
fAlways keep the lid of the door storage com-
partment closed. Objects must not protrude
out of the door storage compartment.
fGive your passenger all of the information in
this chapter.
fNo changes must be made to the wiring or
components of the airbag system.

ABS Brake System
(Antilock Brake System) The ABS system represents a major contribution
to the enhancement of active safety in your vehic-
le. This system prevents the wheels from locking
in a panic stop on almost all road surfaces. With the ABS system in your vehicle, the fol-
lowing areas are enhanced:
Steering, vehicle remains steerable under all bra-
king forces when ABS is engaged.
Good directional control, no swerving caused
by locking of wheels under braking conditions.
Shorter stopping distance, stopping distances
are usually reduced because controlled braking is
maximized.
Prevention of wheel lock up, no brake- induced
sliding and thus no localized tire wear from emer-
gency braking.
The crucial advantage of the ABS system over a
conventional brake system is in the area of
maintaining directional control and maneuverabili-
ty of the car in emergency situations during nor-
mal driving, including panic braking in turns.
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 phy-
sics cannot be overcome, even with ABS.
The risk of accidents due to inappropriate
speed cannot be reduced, even by the ABS.
The driver bears the responsibility for all dri-
ving maneuvers.
fAdapt your driving style to the prevailing road
and weather conditions.
fObey all traffic laws.
Other vehicles not equipped with the ABS
system may not be able to maintain control,
especially on wet or poor road surfaces and
thus may be more likely to impact you from
behind.
fTo minimize that risk, use your ABS system to
increase your ability to maneuver to avoid dan-
gerous situations and not merely to try to stop in the shortest distance possible.

Sport ModeA sportier car set-up is obtained when Sport mode
is switched on. Interventions by the Porsche
control systems are intentionally shifted towards
greater agility and driving performance.
– PASM (Porsche Active Suspension Manage-
ment) is automatically changed to Sport mode,
resulting in a stiffer suspension setup.
– PSM (Porsche Stability Management) control is
sporty. PSM interventions take place later than
in Normal model. The driver can manoeuvre
the vehicle with greater agility at its perform-
ance limits, without having to dispense with the
assistance of PSM in emergency situations.
– The electronic accelerator pedal reacts
sooner, and the engine is more responsive to
throttle inputs. When Sport mode is switched
on, this function is activated only after the
driver has floored the accelerator pedal or
released it briefly.
– The rpm limiter characteristic is “harder”, i.e.
the engine is immediately throttled when the
performance limits are reached.
fPlease observe the appropriate chapters of
this Manual.
Switching Sport mode on and offfPress SPORT button in the center console.
When Sport mode is switched on, the light-
emitting diode in the SPORT button is lit.When Sport mode is switched on, the logo SPORT
appears next to the digital speedometer.
Switching Sport mode on and off simultaneously
activates and deactivates the Sport mode of the
PA S M .
If PASM Sport mode was activated with the PASM
button, PASM remains active.
After the ignition is switched off, Sport mode is au-
tomatically reset to Normal mode.

Porsche Stability Management
(PSM)PSM is an active control system for stabilisation of
the vehicle during extreme driving manoeuvres.
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 phy-
sics 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 dri-
ving 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 dyna-
mic driving maneuvres (e.g. rapid steering mo-
vements, during lane changes or on alterna-
ting 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
stabilise 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.
However, it is possible at any time to achieve
full vehicle deceleration by increasing the foot
pressure slightly.

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 maneuvring 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
measure 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 assis-
tant 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.
