Operation, Safety
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 property damage, serious per-
sonal injury or death.
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.
Serious personal injury or death could result
from loss of control of the vehicle.
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.
Serious personal injury or death could result
from loss of control of the vehicle.
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)
fClose the sliding glass roof (Targa) (with the
sliding glass roof open, the passenger com-
partment 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.

Operation, Safety
Porsche Stability Management
(PSM)PSM is an active control system for stabilization of
the vehicle approaching the performance limits of
driving maneuvers.
Warning!
Risk of an accident, resulting in serious per-
sonal injury or death.
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.
Sensors 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
– Longitudinal accelerationPSM uses these values to determine the direction
of travel indicated by the driver.
PSM intervenes and helps to correct the course if
the actual direction of motion deviates from the
chosen 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/her to adapt his/her
driving style to the road conditions:
– The multifunctional 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.
In order to achieve full vehicle deceleration,
foot pressure must be increased after the
brake pedal has begun vibrating.
Examples of PSM control operations– If the front wheels of the vehicle drift on a
bend, the rear wheel on the inside of the bend
is braked and the engine power is reduced if
necessary.
– If the rear of the vehicle swings out on a bend,
the front wheel on the outside of the bend is
braked.Additional braking functions– Pre-filling the brake system:
The brake system is prepared for possible
subsequent emergency braking if the acceler-
ator pedal is released suddenly and quickly.
The brake system is prefilled and the brake
pads are already applied gently to the brake
discs.
– Brake booster:
In the event of an emergency braking operation
where the pedal force is insufficient, a brake
booster provides the braking pressure neces-
sary for maximum deceleration at all 4 wheels.Advantages of PSM– Best possible traction and lane-holding ability
in all driving situations – even on road surfaces
with varying friction.

Operation, Safety
AntennafAlways unscrew the external antenna before
using an automatic car-wash.
On the Cabriolet and Targa the external antenna is
mounted on the right front fender.
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 telephone
manufacturer's instructions before operating
the telephone.
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.
The dealer is familiar with the technical require-
ments 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.

Instruments, On-Board Computer, Warnings The oil pressure is controlled as required and
should be at least 3.5 bar at an engine speed of
5000 rpm.
The engine oil pressure varies depending on the
engine speed, engine load and engine tempera-
ture.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 whether there is an obvious oil leak on
or under the car.
fIf no oil leak can be detected: With the engine
idling, measure the oil level with the on-board
computer.
fPlease see the chapter “OIL DISPLAY AND
MEASUREMENT OF THE ENGINE OIL LEVEL”
on Page 153.
fPlease see the chapter “ENGINE OIL LEVEL”
on Page 208.
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 engine damage with resultant loss of
control and accident, leading to serious per-
sonal injury or death.
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.

“Sport Plus” mode activated:
In “Sport Plus” mode, the PDK transmission
changes to a shift program designed for driving
on race circuits. 7th gear is not selected.
The gear-changing performance is enhanced
significantly again compared with “Sport” mode.
fPlease see the chapter “SPORT MODE” on
Page 64.
Driving with Launch Control
Driving with Launch Control allows you to achieve
maximum acceleration from a standing start. It is
intended to provide you with a unique enjoyment of
your vehicle under controlled circumstances and
is not intended to be used in any location where it
could be a nuisance to other persons.
Warning!
There is a risk of endangering other road
users if you use this Control in an improper
location or in a situation where other persons
might need to take evasive action due to the
rapid acceleration that this technology
permits.
fLaunch Control is designed to be used in a
controlled environment on closed circuit
driving courses where no vehicle cross traffic
or pedestrian traffic is present.
fUse Launch Control only if conditions permit it
to be applied in a safe manner. fDo not use Launch Control if there is a possibi-
lity it could endanger other persons. Such a
possibility exists if you cannot see that you
have a clear road with no possibility of cross
traffic in your intended direction of driving. Caution!
Stress on components increases dramatically
when starting with maximum acceleration in
comparison with normal driving off. Use of
Launch Control will inevitably reduce the life
of the engaged engine and transmission
components.
Preconditions:
– Launch Control should only be used when the
engine has reached operating temperature.
– “Sport Plus” mode must be switched on (light-
emitting diode in button is on and “SPORT
PLUS” is displayed on the on-board computer).
1. Press the brake with your left foot.
2. Quickly press down the accelerator fully
(kickdown activated) and hold.
The engine speed will flatten out at around
6500 rpm.
“Launch Control active” is displayed on the
on-board computer.3. Release the brake within a few seconds.
Remaining stationary for a long time with
“Launch Control active” can lead to overload-
ing of the transmission.
In order to protect the transmission, the engine
power is then reduced and the “Launch Control
active” process is cancelled.
Shifting gears on the steering wheel
With the shift buttons on the steering wheel, you
can change temporarily from automatic selection
mode D to manual mode M.
For example:
– Shifting down before bends and on entering
built-up areas.
– Shifting down on downward slopes
(engine braking).
– Shifting down for brief spurts of acceleration.
Manual selection mode remains engaged:
– for cornering (depending on the lateral acceler-
ation) and overrunning,
– when the vehicle is stationary (e.g. at a
junction).
The system leaves manual selection mode:
– automatically after approx. 8 seconds (unless
cornering or overrunning),
– after driving off.
