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 accident.
Your vehicle is equipped with a weight sensing sys-
tem for the front passenger's seat in accordance
with U.S. Federal/Canadian Motor Vehicle Safety
Standard 208.
Even if your vehicle is equipped with airbags, the
safety belts must be worn at all times,
because the front airbag system is only deployed
by frontal collisions with an impact of sufficient se-
verity.
Below the deployment threshold of the airbag sys-
tem, and during types of collisions which do not
cause the actuation of the system, the safety belts
provide the primary protection to the occupants
when correctly worn.
Therefore, all persons within the vehicle
must wear safety belts at all times (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 under the padded
steering wheel panel on the driver’s side and, on
the passenger's side, in the dashboard.
The side airbags for the front seats are installed
on the side in the seat backrests.
The head airbags are installed in the door linings.
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 it is deployed, inflat-
ing airbags can result in serious personal in-
jury or death.
Improper handling of the weight sensing sys-
tem can unintentionally impair switching the
passenger's airbag off and on.
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.
fAlways hold the steering wheel by the outer
rim. Never rest your hands on the airbag panel.
fAlways fasten seat belts because triggering
of the airbag system depends on the force and
angle of impact.
fDo not transport heavy objects on or in front of
the passenger’s seat. These could impair the
function of the airbag, the seat belts, and
weight sensing.
fDo not hang objects (e.g. jackets, coats, coat
hangers) over the backrest.fAlways keep the lid of the door storage com-
partment closed. Objects must not protrude
out of the door storage compartment.
fNo changes may 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’s airbag, side airbags and head air-
bags. Doing so may adversely affect the func-
tioning of the airbag system or cause harm to
the occupants if the airbag system should de-
ploy.
fDo not modify the seat coverings. Do not at-
tach additional cushions, protective coverings,
or pillows to the passenger's seat. Do not affix
things to the passenger's seat or cover it with
other materials. Do not cover the back of the
backrest. Do not make changes to the passen-
ger's seat and to the seat base frame.
fDo not undertake any wiring for electrical ac-
cessory equipment in the vicinity of the airbag
wiring harnesses. Doing so may disable the air-
bag system or cause inadvertent inflation.
fIf the warning light comes on, the airbag sys-
tem should be repaired immediately by your
authorized Porsche dealer.
fAlways keep feet in the footwell while driving.
Do not put feet on the dashboard or the seat
area. Do not lean against the inside of the door
or outside the window while the vehicle is mov-
ing.

Porsche Stability Management
(PSM)PSM is an active control system for stabilization of
the vehicle during extreme driving manoeuvres.
The most recent version of PSM (only on vehicles
with four-wheel drive) improves the brake system
functionality.
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.
– It improves the braking functions and shortens
the stopping distance if emergency braking is
needed (only vehicles with four-wheel drive).
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 of the brake pedal pulsing.

Stopping Engine fTurn key back to position 3.
fDo not stop engine immediately after hard or
extended driving.
Keep engine running at increased idle for
about two minutes to prevent excessive heat
build-up before turning off engine.
fTo avoid battery run-down, always remove the
ignition key from the ignition lock.
fMake sure that when you leave the car, even
briefly, you have withdrawn the ignition key.
fEngage the steering lock by moving the steer-
ing wheel to the left or right.
Turn the steering wheel to the locking position
before you switch off the engine so that you
don’t have to exert yourself when locking or
unlocking the steering.
Warning!
Danger of injury. Hot engine compartment
components can burn skin on contact.
fBefore working on any part in the engine com-
partment, turn the engine off and let it cool down sufficiently.
Engine-compartment blower,
radiator fan The radiator and radiator fans are in the front of
the car.
The engine-compartment blower is mounted on
the engine compartment lid.
Warning!
Risk of injury.
After the engine is switched off, the engine-
compartment temperature is monitored for
approx. 30 minutes.
During this period, and depending on tem-
perature, the engine-compartment blower
may continue to run or start to run.
fCarry out work in these areas only with the en-
gine off, the ignition off, and exercise extreme
caution.
Risk of injury. The radiator fans in the front
end of the car may be operating or
unexpectedly start operating when the
engine is switched on.
fCarry out work in these areas only with the en-gine switched off.
Automatic garage door The ignition system in your Porsche may interfere
with your electronically operated garage door.
fTo check this, drive your Porsche close to the
garage door. Make sure not to interfere with
the operating range of the door.
fRun the engine at different speeds.
If the garage door opens or closes without you op-
erating the garage door unit in your car, contact
the dealer who installed the automatic garage
door to have the frequency and/or coding of the
garage door signal changed or modified.

Controls, Instruments Tire pressure function of the on-board
computer
The tire pressure function of the on-board
computer displays the tire pressures (actual
pressure) dependent on temperature in the four
wheels.
You can watch the tire pressure rise as the
temperature increases while driving.
This display is only for information.
fUnder no circumstances should the tire
pressures be changed based on this display.
Displaying the tire pressure function of the
on-board computer
fPush operating lever up or down until the tire
pressure function of the on-board computer
appears.
(The selection field must be switched off.)Pressure info in Tire pressure menu
In accordance with physical principles, the air
pressure changes as the temperature changes.
The tire pressure increases or decreases by
around 1.5 psi (0.1 bar) for every 18°F (10°C)
change in temperature.
The tire pressure monitoring takes this relation-
ship between tire pressure and temperature into
account.
You can read the tire pressures to be
corrected in this display.
The tire pressure to be corrected (refill pressure)
is indicated on the displayed wheel.
Example: If “ –1.5 psi (–0.1 bar)” is displayed,
1.5 psi (0.1 bar) must be added to this tire.
Note
The Tire pressure menu can only be called up
when the vehicle is stationary.Calling up the “Info pressure” display
fPush operating lever forward in order to switch
on the selection field.
fSelect “TPC” with the operating lever.
fPush operating lever forward.
The display changes to the Tire pressure
menu.
fSelect “Info pressure” with the operating lever.
fPush operating lever forward.
Note
After the ignition is switched on, it can take up to
approx. 1 minute before all tire pressures are
displayed. Dashes (“-.-”) appear instead of the tire
pressures.

System learningThe tire pressure monitoring begins to “learn” the
wheels after a wheel change, wheel transmitter
replacement or update of the tire settings. During
this process, the tire pressure monitoring recog-
nises the tires and their locations. The on-board
computer displayes the message “TPC inactive –
system learning”.
The tire pressure monitoring requires a certain
amount of time to learn the wheels. During this
time, the current tire pressures are not available
on the on-board-computer:
– The display of the Tire pressure function of the
on-board computer shows lines.
– The required pressures for cold tires at 68°F
(20°C) are indicated in the Info pressure
display in the Tire pressure menu.
– Tire pressure warnings are issued without tire
pressure and position information (figure) as
soon as the vehicle’s own wheels have been
detected and the tire pressure warning light
has gone out.Position and pressure information is displayed as
soon as the tire pressure monitoring has assigned
the wheels identified as belonging to the vehicle to
the correct wheel positions.
The wheel learning process takes place
exclusively when the vehicle is being driven.
fManually check the tire pressure at all wheels
and correct the tire pressure to the required
value.
Changing a wheel and replacing tiresfNew wheels must be fitted with radio transmit-
ters for the tire pressure monitoring.
Before tires are changed, the battery charge
state of the wheel transmitters should be
checked at an authorized Porsche dealer.
fSwitch the ignition off when changing a wheel.
The tire settings on the on-board computer must
be updated after changing a wheel.
A message appears if the characteristics of the
new tires do not agree with the on-board computer
settings.
fUpdate the on-board computer settings when
the vehicle is stationary the next time.
