Never invite car theft! An unlocked car with the key in the ignition lock in-
vites car theft.
A steering wheel lock and a gong alarm are stan-
dard equipment in your Porsche.
The gong alarm will sound if you open the driver’s
door while the key is still in the ignition lock. It is
your reminder to pull the key out of the ignition
lock and to lock the doors.
Warning!
Any uncontrolled movement of the vehicle
may result in serious personal injury and pro-
perty damage.
Never leave your vehicle unattended with the
key in the ignition lock, especially if children
and/or pets are left unattended in the vehic-
le. They can operate power windows and
other controls. If the engine is left running,
they may accidentally engage the shift lever.
fAlways remove the ignition key.
fAlways set the parking brake.
fLock the doors with the key or with the remote control.
Warning!
Risk of a serious accident.
The steering column will lock when you re-
move the key while you are driving or as the
car is rolling to a stop. You will not be able to
steer the car.
fNever remove the key from the steering lock while you are driving. To protect your vehicle and your possessions
from theft, you should always proceed as fol-
lows when leaving your vehicle:
fClose windows.
fClose convertible top
(with the convertible top open, the passenger
compartment monitoring system is always
switched off).
fLock glove compartment.
fRemove ignition key.
fClose storage tray between the seats.
fRemove valuables (e.g. car documents, tele-
phone, house keys) from the car.
fLock doors.

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.

Controls, Instruments If the battery voltage drops abruptly, a warning
m e s s a g e w i l l b e d i s p l a y e d b y t h e o n - b o a rd c o m p u -
ter.
If the warning is displayed by the on-board
computer while the engine is running or while
driving:
fStop the car in a safe place and stop the
engine.
Possible causes
– Defect in the battery charging system.
– Broken drive belt. Warning!
Risk of an accident and risk of engine dam-
age.
A broken drive belt means there is no power
assistance to the steering (more effort is re-
quired to steer) and coolant pump function
will stop.
fDo not continue driving.
fHave the fault remedied at the nearest author-ized Porsche dealer. The warning light in the instrument panel comes
on when the ignition is first turned on and remains
on briefly as a bulb check. If the light does not
come on, have the bulb replaced promptly.
If the warning lights in the instrument panel and on-
board computer come on and remain on while
driving, it suggests:
– a potential engine control problem and the
need for system service or
– an improperly fastened tank cap or
– refuelling with engine running.
Although the vehicle is usually driveable and will
not require towing, see your dealer for service as
soon as possible.
Caution!
If the Check engine light in the instrument
panel is flashing, severe catalytic converter
damage and power loss will soon occur.
Prolonged driving with the Check engine light
on could cause damage to the emission con-
trol system. It also could affect fuel economy
and driveability.
fHave the fault remedied at the nearest author-ized Porsche dealer immediately.

Car Telephone and
Aftermarket Alarms Important legal and safety information
regarding the use of cellular telephones:
Some states may prohibit the use of cellular tele-
phones while driving a vehicle. Check the laws and
regulations on the use of cellular telephones in the
areas where you drive.
Danger!
Risk of an accident.
Severe personal injury or death can result in
the event of an accident.
Looking away from the road or turning your
attention away from your driving can cause
an accident and serious or fatal injury.
When using your cellular telephone, you should al-
ways:
fGive full attention to your driving - pull off the
road and park before making or answering a
call if traffic conditions so require; and
fKeep both hands on the steering wheel - use
hands-free operation (if available) - pull off the
road and park before using a hand-held tele-phone. It is essential to observe the instructions of
the telephone manufacturer before putting
the telephone into operation.
Any portable telephone or radio transmitter which
is used in a Porsche must be properly installed in
accordance with the technical requirements of
Porsche.
The transmission power must not exceed
10 W.
The devices must possess a type approval for
your vehicle and have an “e” symbol.
If you should require equipment with transmission
power values greater than 10 W, please consult
your authorized Porsche dealer for this purpose.
He is familiar with the technical requirements for
installing devices of this kind.
The antennas for all radios and telephones with a
transmitting antenna must be externally mounted.
The improper installation of radios or telephones
or use of a radio or telephone with a transmitting
antenna inside the car may cause the warning
lights to come on.
Improper installation of such equipment can crea-
te a discharged battery or excessive current draw
from added equipment. If aftermarket systems are installed by non-dealer-
ship technicians or outside the selling dealer, pro-
blems may result. Installation of aftermarket
equipment is not covered under the New Car War-
ranty.
fConsult your authorized Porsche dealer about
the installation of non Porsche approved equip-
ment.
Reception quality
The reception quality of your car telephone will
change constantly when you are driving. Interfe-
rence caused by buildings, landscape and
weather is unavoidable. It may become particular-
ly difficult to hear when using the hands-free func-
tion due to external noise such as engine and wind
noise.
Automatic car-wash
fUnscrew the external antenna before using an
automatic car-wash.

Shifting Gear
151
M - Manual Selection Mode The currently selected gear is retained if you
change from D to M.
If you shift from M to D, the gear-changing map
suitable for your current driving style is selected
and the appropriate gear is selected.
Warning!
The kickdown function is not active in manual
selection mode “M”.
fTherefore shift down manually when accelera-ting (e.g. to overtake). Two toggle switches in the upper steering-wheel
spokes let you comfortably and reliably select the
five forward gears.
Shifting up
fPress upper part (+) of a toggle switch.
Shifting down
fPress lower part (–) of a toggle switch.
Depending on driving speed and engine speed,
you can shift up or down at any time.
Gear changes which would exceed the upper or lo-
wer engine-speed limit are not executed by the
controller.
You can shift down two gears at once by quickly
pressing the toggle switches twice.
If the engine-speed limit is reached, an auto matic
upward shift is performed or, just before idling
speed is reached, a downward shift is performed.
fSelect an appropriately low gear on upward
and downward slopes.
This will ensure optimum use of engine power
and engine braking. If manual mode fails, the control electronics
switch to automatic mode. In this event, the
instrument cluster will display selector lever posi-
tion D.
fTo remedy the fault, please consult an authori-
zed Porsche dealer.

Power Steering
Warning!
Risk of accident.
When the engine is stopped (e.g. when on
tow) or the power steering has failed there is
no steering assistance.
Therefore, substantially more force will have
to be exerted in order to steer.
fExercise great care when being towed.
fHave the fault remedied at your nearest autho-rized Porsche dealer. Note
The flow noise heard at full steering lock is design-
related and does not indicate a defect in the stee-
ring system.
Checking hydraulic fluid fPlease observe the chapter “EXERCISE EXTRE-
ME CAUTION WHEN WORKING ON YOUR VE-
HICLE” on Page 168.
The hydraulic fluid reservoir is located in the engi-
ne compartment.
fOnly use hydraulic fluid authorized by Porsche.
fPlease observe the chapter “CAPACITIES” on
Page 266.
fCheck the fluid level with the engine stopped
and cold (approximately 68°F/20°C).
1. Open the engine compartment lid.
Please observe the chapter “OPENING ENGINE
COMPARTMENT LID” on Page 185.
2. Open the reservoir cap.
3. Wipe measuring rod.
Close lid and reopen. The fluid level should lie
in the area below the ”Cold“ marking.
Add hydraulic fluid if necessary.
4. Close cap carefully.
Close engine compartment lid.
Noticeable loss of fluid indicates leakage in the
system.
The cause should be remedied immediately at an
authorized Porsche dealer.

Practical Tips, Emergency Service
Putting vehicle into operationAfter the battery is connected or after an exhaus-
tively discharged battery is charged, the multi-
functional PSM light lights up on the instrument
panel and a message appears on the on-board
computer to indicate a fault.
This fault can be remedied with a few simple
steps:
1. Start the engine.
2. With the vehicle stationary, perform a few
steering movements to the left and right and
then drive a short distance in a straight line
until the multifunctinal PSM light goes out and
the message on the on-board computer
disappears.
3. If the warnings do not disappear, then:
Drive carefully to the nearest qualified
specialist workshop.
Have the fault remedied.
4. After the warnings disappear, stop the vehicle
in a suitable place.
5. Perform adaptation of the power windows:
Please observe the chapter “STORING END
POSITION OF THE WINDOWS” on Page 29.Ignition key/ignition lock
