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.
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.

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.

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 255.
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 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 automat-
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).
