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.

General information regarding the
on-board computer functionsRange on remaining fuel
The range on remaining fuel is continuously recal-
culated during the journey based on the fuel level,
current consumption and average consumption.
The more the fuel level falls, the more spontan-
eously the display reacts. For this reason, the
range on remaining fuel is not displayed if less
than 9 miles (15 kilometers).
If the vehicle's inclination changes while driving or
refuelling, incorrect range information may tempo-
rarily be given.
Note
If the tank is nearly empty and you top up with only
a small quantity of fuel, an accurate range on re-
maining fuel is impossible.Average consumption and average speed
The values displayed are based on the distance
travelled since the last reset to “zero”.
You can set the starting time for a measurement
before or during the trip.
Switching the ignition off does not reset the meas-
urements. It is therefore possible to collect values
over long periods.
Disconnecting the car battery will cause these
memories to be erased.
Tire pressure
The Tire pressure function of the on-board com-
puter displays the tire pressures dependent on
temperature in the four wheels. You can watch the
tire pressure rise and fall while driving.
The display is only for information. To correct the
tire pressures, always use the displayed values
from the “Info pressure” display in the Tire pres-
sure menu.

Controls, InstrumentsIf the ignition key is withdrawn and the door is
opened while the lights (not the parking light or
Welcome Home lighting) are on, a chime warns of
possible battery discharge.
In some countries, differences are possible
due to provisions of law.
Note on operation
Further individual light functions (e.g. daytime driv-
ing lights) are available in vehicles with the Sport
Chrono package.
Please observe the chapter “Individual Memory” in
the separate PCM operating instructions.
Welcome Home LightingSwitching onfMove light switch to the HOME position.
For improved visibility and security when you get
in and out of the car, the fog lights and the tail
lights remain on for a certain period of time:
–When you get out of the car, the lights are
turned on for approx. 30 seconds after the
door is opened. The off-delay time resumes
when the vehicle is locked.
On vehicles with the Sport Chrono package,
the PCM can be used to set the off-delay time.
This setting also changes the lighting period
for unlocking the vehicle.
Please observe the chapter “Individual
Memory” in the separate PCM operating
instructions.
The lights are turned on for approx. 30 seconds
when the vehicle is unlocked.
The lights go out if the ignition is switched on or
when leaving the Welcome Home lighting
If the ignition key is withdrawn and the door is ope-
ned while the lights (not the parking light left/right)
are on, a gong warns of possible battery dis-
charge.
In some countries, differences are possible
due to provisions of law.

before putting the PCM into operation.
fPlease observe the chapter “LOAD SWITCH-
OFF AFTER 2 HOURS OR 7 DAYS” on Page
246.
Warning!
There is a danger of accident if you set or
operate 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 resul-
ting in serious personal injury or death.
fOperate the components while driving only if
the traffic situation allows you to do 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. 31 miles (50 km) must be dri-
ven in order for the navigation system to complete
the process of fine calibration.
The same applies when the tires are changed (e.g.
summer/snow 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 after
being switched on before it determines the current
location.
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 becomes operational again.

Allocating signals to the buttonsfPlease follow the operating instructions for the
original hand-held transmitter.
Prior to programming the HomeLink for the
first time
The following process deletes the standard codes
set at the factory. Do not repeat the process if you
program further buttons.
fKeep the two outer buttons 1 and 3
depressed for approx. 20 seconds until light-
emitting diode A begins to flash quickly.
All programmed signals of buttons 1 to 3 are
deleted.HomeLink with fixed code system
1. Press the desired button until the light-emitting
diode begins to flash slowly.
You then have approx. 5 minutes to perform
steps 2 and 3.
2. Hold the original hand-held transmitter approx.
0 to 12 in. (0 to 30 cm) in front of the marked
position (figure) on the vehicle.
3. Press the transmit button on the original hand-
held transmitter until the fog lights flash three
times (up to approx. 45 seconds).
4. Repeat steps 1 to 3 to allocate other buttons.
Note
Several attempts with different distances between
the vehicle and the original hand-held transmitter
might be necessary.
The fog lights will flash once the 5 minutes have
been exceeded. Programming must be repeated
from the beginning in this case.HomeLink with changeable code system
1. Allocate the required keys as for the systems
with fixed code (steps 1 to 3).
2. To synchronise the system:
Press the programming button on the receiver
for the garage door actuator.
Afterwards, you usually have approx.
30 seconds to initiate step 3.
3. Press the allocated HomeLink button twice.
(With some devices, the button to be allocated
must be pressed a third time in order to
complete the setting process.)
4. Repeat the programming steps to allocate
other buttons.
Note
fPlease consult an authorized Porsche dealer if
you have not been able to successfully allocate
signals for the garage door opener to the
buttons even though you have carefully
followed the instructions in this chapter and
the operating instructions for the original hand-
held transmitter.

Shifting Gear
167
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.
PSM switched off and/or Sport mode
switched on
fPlease observe the chapter “SWITCHING OFF
PSM” on Page 65.
fPlease observe the chapter “SPORT MODE” on
Page 63.
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
The restriction can be cancelled for one gear
change by depressing the accelerator to
kickdown. If, for example, the engine speed limit
is reached during overtaking and the automatic
upshift does not occur, the transmission in this
case shifts up by accelerating to kickdown.
fDepress the accelerator pedal beyond the
full-throttle point (kickdown).

Maintenance, Car Care

Paint fNever rub a dusty car with a dry cloth since
dust particles are abrasive and could dull and
damage the surface finish.
The paintwork of your car is exposed to all types
of mechanical and chemical conditions, particular-
ly climatic ones such as bright sunlight, rain, frost
and snow. Ultraviolet light, rapid changes in tem-
perature, rain, snow, industrial dust and chemical
deposits constantly attack the paint which is only
able to withstand such exposure in the long term
if it is given regular care and attention.
fDo not apply silicone polishes to the winds-
hield, windows or convertible top.
fDo not treat matt-painted components with
preservatives or polishes as this will spoil the
matte effect. Preservation
The paint surface becomes dull over time due to
weathering. It is therefore necessary to preserve
the paint regularly.
This keeps the paint shiny and elastic. Dirt is
prevented from adhering to the paint surface and
industrial dust is prevented from penetrating the
paint.
Provided it is washed and treated with preserva-
tive regularly, the brand new finish of your vehicle
will be retained for years to come.
fSimply apply paint preservative after washing
the vehicle and polish it smooth.
Polishing
Do not resort to using Porsche polish until it beco-
mes evident that the normal preservatives no lon-
ger produce the desired finish.
Spots and stains
fRemove tar stains, grease, oil spots and dead
insects as soon as possible with Insect Remo-
ver. They can cause discoloration if allowed to
remain on the paintwork.
fWash the affected area immediately after trea-
ting it. Minor paint damage
fHave minor paint damage, such as scratches,
scores or chips caused by flying stones, re-
paired immediately by your authorized
Porsche dealer before corrosion sets in.
However, if there are already traces of corrosion,
they must first be removed carefully and tho-
roughly. Coat the area with a rust-proofing primer
and finish off with a top coat. The paint code and
color number are found on the data bank in the
Maintenance booklet.
