Airbag SystemsThe airbags in combination with the safety belts
make up a safety system which offers the driver
and the passenger the greatest known protection
from injuries in case of an accident.
Even though 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 the occupants
would receive substantial additional injuries if the
airbags did not deploy.
Airbags protect the face and upper body, while
simultaneously 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.
fS i t b a c k a s f a r f ro m t h e d a s h b o a rd o r s t e e r i n g
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.

fDo not add any additional coverings or stickers
to the steering wheel or in the area of the pas-
senger airbag, side airbags and head airbags.
Doing so may adversely affect the functioning
of the airbag system or cause harm to the oc-
cupants if the airbag system should deploy.
fDo not undertake any wiring for electrical ac-
cessory equipment in the vicinity of the airbag
wiring harnesses. Doing so may disable the
airbag system or cause inflation.
fIf the warning light comes on, the airbag sys-
tem should be repaired immediately by your
authorized Porsche dealer.
Note
Airbag components (e.g. steering wheel, door
trim, seats) may be disassembled only by an au-
thorized Porsche dealer.
When disposing of a used airbag unit, our safety
instructions must be followed. These instructions
can be obtained at any authorized Porsche dealer. Faults are indicated by a warning light in the instru-
ment panel and a message on the on-board com-
puter.
fIn the following cases you should immedi-
ately consult an authorized Porsche deal-
er in order to assure the airbag system is
functioning properly:
– If the warning light does not light up when the
ignition is switched on or
– If the warning light does not go out once the
engine is running or
– If the warning light appears while driving.
fPlease observe the chapter “WARNINGS ON
THE INSTRUMENT PANEL AND THE ON-
BOARD COMPUTER” on Page 105.
Warning light “PASSENGER AIRBAG OFF”fPlease observe the chapter “KEY-OPERATED
AIRBAG DEACTIVATION DEVICE” on Page 49.
Airbag maintenanceIn order to ensure long-term functioning, the air-
bag system must be inspected by an authorized
Porsche dealer at the intervals recommended in
your Maintenance booklet.
Important information
If you sell your Porsche, notify the purchaser that
the vehicle is equipped with airbags, and refer
them to the chapter, “Airbag Systems”, in the own-
er’s manual (safety and disposal rules).
Further information on the airbag system can be
found on labels on the sun visors, as well as on all
airbag components.

ABS Brake System
(Antilock Brake System)The ABS system represents a major contribution
to the enhancement of active safety in your vehi-
cle. This system prevents the wheels from locking
in a panic stop on almost all road surfaces. With the ABS system in your vehicle, the
following areas are enhanced:
Steering, vehicle remains steerable under all
braking 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 main-
taining directional control and maneuverability of
the car in emergency situations during normal driv-
ing, 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
physics 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
driving 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.

Porsche Stability Management
(PSM)PSM is an active control system for stabilization 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
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
–Steering angle
– Lateral acceleration
– Rate of turn about the vertical axis
– Brake pressure
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 lights up.
– 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 begin-
ning the brake pedal pulsing.
