Keys fPlease observe the chapter “ALARM SYSTEM,
PASSENGER COMPARTMENT MONITORING”
on Page 26.
fPlease observe the chapter “CENTRAL LO-
CKING” on Page 22.
Two main keys and one spare key are supplied
with your Porsche.
These keys operate all the locks on your vehicle.
fBe careful with your car keys: do not part with
them except under exceptional circumstances.
fTo avoid battery run-down, always remove the
ignition key from the ignition lock.
Replacement keys Replacement car keys can be obtained only from
your authorized Porsche dealer, and this can
sometimes be very time-consuming.
You should therefore always keep the spare key on
your person.
Keep it in a safe place (e.g. wallet), but under no
circumstances in or on the vehicle.
The key codes of new keys have to be “reported”
to the car control unit by your authorized Porsche
dealer.
The key grip of the spare key can be exchanged
for a main-key grip.
Disabling key codes
If a key is lost, the key codes can be disabled by
an authorized Porsche dealer.
All the remaining car keys are required for this pur-
pose.
Disabling the code ensures that the car can be
started only using authorized keys.
Note
fPlease note that the other locks can still be
opened with the disabled key.
Immobilizer There is a transponder (an electronic component)
in the key grip, containing a stored code.
When the ignition is switched on, the ignition lock
checks the code.
The immobilizer can be deactivated and the en-
gine started only using an authorized ignition key.
Switching off the immobilizer
fInsert the ignition key into the ignition lock.
If the ignition is left on for more than 2 minutes
without the engine being started, the immobilizer
is reactivated.
fIf this happens, turn the ignition key back to the
3 position before starting the engine.
Please observe the chapter “IGNITION/
STARTER SWITCH WITH ANTI-THEFT
STEERING LOCK” on Page 72.
Switching on the immobilizer
fRemove ignition key.Security Wheel Bolts fIf wheels have to be removed during a work-
shop visit, do not forget to hand over the sock-
et for the security wheel bolts along with the
car key.

on Page 36.Both car doors and the filler flap can be centrally
unlocked or locked with the remote control.
The vehicle cannot be locked if the driver’s door is
not completely closed.
A short signal from the alarm horn will draw
your attention to the fact that the following
components are not completely closed when you
try to lock the vehicle:
– Passenger’s door
– Luggage compartment lid
– Engine compartment lid
– Glove compartment
Unlocking the vehicle by using the key in the door
lock and opening the door may activate the alarm
system within 10 seconds.

the separate PCM operating instructions.
Automatic relocking If the car is unlocked by remote control and none
of the car doors is opened within approx.
60 seconds, automatic relocking takes place.
This relocking time can be adapted to your individ-
ual requirements (10 - 100 seconds) by an author-
ized Porsche dealer.

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.

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.

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.
