Management (PCM) fRefer to the separate operating instructions
before putting the PCM into operation.
fPlease observe the chapter “LOAD SWITCH-
OFF AFTER 2 HOURS OR 7 DAYS” on
Page 233.
Warning!
There is a danger of accident if you set or op-
erate the on-board computer, radio, navi-
gation system, telephone or other equipment
when driving.
This could distract you from the traffic and
cause you to lose control of the vehicle re-
sulting in serious personal injury or death.
fOperate the components while driving only if
the traffic situation allows you to do so safely.
fCarry out any complicated operating or setting procedures only with the vehicle stationary.The reception conditions for the radio module inte-
grated in the PCM change continuously as you
drive. Interference from buildings, terrain and the
weather is unavoidable.
FM stereo reception is particularly susceptible to
varying reception conditions.
Electronic accessories should only be retrofitted
by a qualified specialist workshop.
Accessories which have not been tested and
approved by Porsche may impair radio reception.
NavigationWhen put into operation for the first time, a
distance of approx. 30 miles (50 km) must be
driven in order for the navigation system to
complete the process of fine calibration.
The same applies when the tires are changed (e.g.
summer/winter tires) or new tires fitted.
Full location accuracy is not yet achieved during
the fine-calibration process.
If the vehicle has been transported (e.g. ferry, car
train), the system may take a few minutes to deter-
mine the current location after it has been
switched on.
Serious tire slip (e.g. spinning wheels on snow)
may result in temporarily inaccurate navigation.
When the battery has been disconnected, it may
take up to 15 minutes before the navigation
system is operational again.

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.

Tiptronic SThe Porsche Tiptronic is a five-speed transmission
with an “automatic” and a “manual” selection
mode.
In automatic selection mode (selector lever po-
sition D), gear changing is automatic.
You can change temporarily from automatic to
manual mode using the rocker switches on the
steering wheel.
In manual selection mode (selector lever posi-
tion M), you change gear using the rocker switch-
es on the steering wheel.
You can change between selector lever position D
and M as you wish while driving.
Note
Take care not to operate the rocker switches on
the steering wheel inadvertently in either auto mat-
ic or manual mode, thereby triggering undesired
gear changes.Keylock positionThe ignition key can be withdrawn only in selec-
tor lever position P.
Changing the selector lever positionThe selector lever is locked with the ignition key
withdrawn.
The selector lever can be moved from position P
or N only with:
– The ignition switched on
– The brake pedal pressed and
– The release button pressedRelease button
The release button (arrow) in the selector lever
prevents unintentional gear changes.
The release button must be pressed when shifting
to position R or P.
StartingThe engine can be started only if the brake pedal
is depressed and the selector lever is in position
P or N.Moving offfOnly select the desired position for moving off
(D, M or R) when the engine is idling and the
brake pedal is depressed.
fSince the vehicle creeps when in gear, do not
release the brake until you want to move off.
fAfter selecting a gear, do not accelerate until
you can feel that the gear is engaged.

Shifting Gears Shifting gears on the steering wheel
With the rocker switches on the steering wheel,
you can change temporarily from automatic
selection mode D to manual mode M.
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.
– Selecting 1st gear for starting off.
Manual selection mode remains engaged:
– for cornering (depending on the lateral
acceleration) 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),
– if you depress the accelerator for kickdown,
– after moving off.Temporary change-down
Conditions:
Speed is higher than approx. 33 mph (54 km/h).
fRapid acceleration.
The Tiptronic temporarily changes to the
sportiest gear-changing map, i.e. to the high-
est possible gear-changing points.
Correspondingly, the transmission shifts down
immediately by one or two gears.
Ending the function:
fRelease the accelerator markedly
(by approx. 25%).
Kickdown
The kickdown function is active in selector lever
position D, even if you temporarily change to man-
ual mode M using the rocker switches on the
steering wheel.
fFor optimum acceleration, e.g. when overtak-
ing, depress the accelerator pedal beyond the
full-throttle point (kickdown).
The transmission shifts down depending on the
speed of travel and engine speed.
Upward shifts occur at the highest possible engine
speeds.
These gear-changing speeds remain active until
the accelerator is released to approx. 80% of the
full-throttle position.
M - Manual selection modeThe currently selected gear is retained when you
change from D to M.
If you change from M to D, the gear-changing map
suitable for your current driving style is selected
and the appropriate gear is chosen.
Warning!
The kickdown function is not active in manual
selection mode “M”.
fTherefore shift down manually when accelerat-ing (e.g. to overtake).

Shifting Gears

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.

Shifting Gears
StoppingfFor a brief stop (e.g. at a traffic light), leave the
selector lever in drive position and hold the ve-
hicle with the brake pedal.
fFor a longer stop with the engine running, se-
lect position N (neutral) and hold vehicle in po-
sition with the foot brake.
Select lever position D only when the foot
brake pedal is depressed.
fDo not hold the car on a slope using the
accelerator. Use the brake pedal or the hand-
brake instead.
fBefore leaving the vehicle, always apply the
handbrake and move the selector lever to po-
sition P.
ParkingfGo easy on the accelerator!
fWhen parking or maneuvering in a small
space, control the speed by careful use of the
footbrake.Driving in winterIn wintry road conditions it is advisable to take
steep inclines in manual mode. This prevents the
occurrence of gear changes that could cause
wheelspin.Tow-starting, towingfPlease observe the chapter “TOWING” on
Page 259.Reduced driving programA transmission fault is indicated by the following
symptoms:
–The 4th gear display on the instrument clus-
ter flashes.
– The warning “Tiptronic emergency run” ap-
pears on the on-board computer.
– The transmission no longer shifts.
Warning!
Reverse gear lock monitoring is disabled in
the emergency running program.
Damage to the vehicle may result as well as
loss of control, if the vehicle is moving for-
ward fast enough to cause rear wheel lockup.
fDo not shift into R while the vehicle is moving forward.
Proceed as follows in the event of a transmission
fault:
1. Stop in a safe place.
2. Move selector lever to position P, switch the ig-
nition off and wait for 10 seconds.
3. Start the engine.
2nd gear in selector position D and reverse
gear R are now available.
4. Have the fault seen to immediately at an au-
thorized Porsche dealer.

Maintenance, Car Care
Exercise Extreme Caution when
Working on your Vehicle
Danger!
Ignoring the following instructions may
cause serious personal injury or death.
fThe engine compartment of any motor vehicle
is a potentially hazardous area. If you are not
fully familiar with proper repair procedures, do
not attempt the adjustments described on the
following pages.
This caution also applies to the entire vehicle.
fO n l y w o r k o n y o u r v e h i c l e o u t d o o r s o r i n a w e l l
ventilated area.
fEnsure that there are no open flames in the
area of your vehicle at any time when fuel
fumes might be present. Be especially cau-
tious of such devices such as hot water heat-
ers which ignite a flame intermittently.
fBefore working on any part in the engine com-
partment, turn the engine off and let it cool
down sufficiently. Hot engine compartment
components can burn skin on contact.
fBe alert and cautious around engine at all
times while the engine is running.
If work has to be performed with the engine
running, always set the parking brake, and
make sure the shift lever is in neutral position
or the selector lever in position P.fIn particular, be very careful to ensure that
items of clothing (ties, shirt, sleeves etc.),
jewelry, long hair, hand or fingers cannot get
caught in the engine-compartment blower, fan,
belts or other moving parts.
The radiator and radiator fans are in the front
of the car.
The engine-compartment blower is mounted
on the engine-compartment lid.
The engine-compartment blower can start or
continue running as a function of temperature,
even with the engine switched off.
Carry out work in these areas only with the en-
gine off, the ignition switched off, and exercise
extreme caution.
fYour Porsche is equipped with an electronic ig-
nition system. When the ignition is on, high
voltage is present in all wires connected with
the ignition system; therefore, exercise ex-
treme caution when working on any part of the
engine while the ignition is on or the engine is
running.
fAlways support your car with safety stands if it
is necessary to work under the car.
fWhen working under the car without safety
stands but with the wheels on the ground,
make sure the car is on level ground, the
wheels are blocked, and that the engine
cannot be started.
Remove the ignition key. fDo not smoke or allow an open flame around
the battery or fuel.
Keep a fire extinguisher in close reach.
fIncomplete or improper servicing may cause
problems in the operation of the car. If in doubt
about any servicing, have it done by your
authorized Porsche dealer.
Improper maintenance during the warranty
period may affect your Porsche warranty cov-
erage.
fSupplies of fluids, e.g. engine oil, brake fluid or
coolant, are hazardous to your health.
Keep these fluids out of children’s reach and
dispose of them in accordance with the appro-
priate regulations.
fSome countries require additional tools and
special spare parts to be carried.
Please make enquiries before driving abroad.
