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.

If the ignition key is withdrawn and the door is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.

Automatic Headlight Beam
Adjustment Vehicles with Bi-Xenon headlights feature
automatic headlight beam adjustment.
When the ignition is switched on, the level of the
headlight beam automatically changes in accord-
ance with the vehicle load.
The level of the headlight beam is automatically
kept constant during acceleration and braking. Checking operation 1. Switch the low beam on.
2. Insert ignition key and switch ignition on.
The light beam first dips all the way down and
is then adapted to the vehicle load.
If this test item is not met, the headlight beam
adjustment system must be checked by an author-
ized Porsche dealer.

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 your authorized Porsche dealer
if you have not been able to program the
buttons successfully even though you have
carefully followed the instructions in this
chapter and the operating instructions for the
original hand-held transmitter.

Porsche Communication
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.

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.

Maintenance, Car Care
Changing the brake fluid Brake fluid absorbs moisture from the air over
time. This accumulation of water lowers the boil-
ing point and, under certain operating conditions,
can affect the braking action.
Therefore have the brake fluid changed in accord-
ance with the change intervals stated in the
brochure “Maintenance”. – The warning lights on the instrument panel and
on the on-board computer indicate an insuffi-
cient brake fluid level.
– If the warning light lights up on the instrument
panel and the warning message appears on
the on-board computer in combination with a
larger pedal travel, a brake circuit may have
failed.
If the warning lights should light up whilst
driving:
fStop immediately in a suitable place.
fDo not continue driving.
Consult an authorized Porsche dealer.
