Controls, Instruments
Never invite car theft! An unlocked car with the key in the ignition lock
invites car theft.
A steering wheel lock and a gong alarm are
standard 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
property damage.
Never leave your vehicle unattended with the
key in the ignition lock, especially if children
and/or pets are left unattended in the vehi-
cle. 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 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
follows when leaving your vehicle:
fClose windows.
fClose lifting/sliding roof
fClose convertible top (with the convertible top
open, the passenger compartment monitoring
system is always switched off)
fRemove ignition key.
fEngage steering lock.
fLock glove compartment.
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 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.

Controls, Instruments With the engine warmed up and running at a speed
of 5000 rpm, the engine oil pressure should be
approx. 3.5 bar.If oil pressure drops abruptly and a message
is displayed on the on-board computer when
the engine is running on or when driving:
fStop immediately in a suitable place.
fSwitch off the engine.
fCheck oil level.
Please observe the chapter “OIL DISPLAY AND
MEASUREMENT OF THE ENGINE OIL LEVEL”
on Page 101.
Please observe the chapter “ENGINE OIL
LEVEL” on Page 181.
fAdd engine oil if necessary.
Caution!
Risk of engine damage.
fDo not continue driving if there is an obvious oil
leak.
fDo not continue driving if the warning lights
come on even though oil level is correct.
fHave the fault remedied at the nearest authorized Porsche dealer.If the battery voltage drops abruptly, a warning
message will be displayed by the on-board compu-
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.

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 cre-
ate 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,
problems 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. Interfer-
ence caused by buildings, landscape and weather
is unavoidable. It may become particularly difficult
to hear when using the hands-free function due to
external noise such as engine and wind noise.
Automatic car-wash
fUnscrew external antennas before using an au-
tomatic car-wash.

Shifting Gears
149
Two rocker switches in the upper steering-wheel
spokes let you comfortably and reliably select the
five forward speeds.
Shifting up
fPress upper part (+) of a rocker switch.
Shifting down
fPress lower part (–) of a rocker 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
lower engine-speed limit will not be executed by
the controller.
You can change down two gears by quickly press-
ing the rocker switches twice.
If the engine-speed limit is reached, an automatic
upward shift is performed or, just before idling
speed is reached, a downward shift is performed.
Select an appropriately low gear on upward and
downward slopes.
This will ensure optimum use of engine power and
engine braking.PSM switched off and/or Sport mode
switched on
fPlease observe the chapter “PORSCHE STABI-
LITY MANAGEMENT (PSM)” on Page 65.
fPlease observe the chapter “SPORT MODE” on
Page 64.
If the PSM is switched off and/or Sport mode is
switched on, an automatic upshift does not occur
when the engine speed limit is reached.
Cancelling upshift suppression
This restriction can be cancelled for one gear
change by depressing the accelerator to kick-
down. If, for example, the engine speed limit is
reached during overtaking and the automatic up-
shift does not occur, the transmission in this case
shifts up by accelerating to kickdown.
fDepress the accelerator pedal beyond the full-
throttle point (kickdown).Manual mode failure
If manual mode fails, the control electronics
switch to automatic mode. In this event, the instru-
ment cluster will display selector lever position D.
fHave the fault remedied at an authorized
Porsche dealer.
