Note on operation
Depending on the equipment of your vehicle,
some information or functions may not be avail-
able on the multi-purpose display (e.g. navigation,
compass, audio system or tire pressure).

–Top display A:
Audio information (e.g. station, frequency, CD)
–Centre display B:
Information about range on remaining fuel,
average speed, compass, navigation, tyre
pressure, or access to main menu

General informationRange on remaining fuel
The range on remaining fuel is continuously
recomputed while driving based on fuel level,
current consumption and average consumption.
Average speed
The displayed values are based on the distance
travelled since the last reset to “zero”.
Note on operation
Switching the ignition off does not reset the
measurements. Values can thus be collected over
long periods. Disconnecting the vehicle battery
clears the memories.
Further on-board computer functions can be dis-
played in the PCM.
Please follow the separate operating instructions
for PCM.
Main MenufOperate the rocker switch until the basic
screen MAIN MENU is displayed.
fPress RESET switch.The submenus are listed:

Tire PressureThe tire pressure monitoring system monitors the
pressure in the four road wheels and warns the
driver if the pressure is too low.
The display as well as the settings for tire pres-
sure monitoring are done on the multi-purpose dis-
play in the TYRE PRESSURE menu.
However the tire pressure must be set manually
on the wheel.
The tire pressures to be monitored for tire type
are permanently set in the tire pressure
monitoring system and cannot be changed.
The driver is solely responsible for filling the tires
correctly and for selecting in the multi-purpose dis-
play.
Danger!
Risk of serious personal injury or death.
Driving the vehicle with low tire pressure in-
creases increases risk of a tire failure and re-
sulting loss of control. Furthermore, low tire
pressure increases rate of wear of the affect-
ed tires.
fWhen a flat tire has been displayed, immedi-
ately stop in a suitable place and check the
tires for damage. If necessary remedy the
damages with a tire sealant.
fDo not by any means continue to drive with
leaking tires.
fDefective tires must be immediately replaced
by a specialist workshop.
Tire repairs are not permissible under any
circumstances.
fSealing the tire with the tire sealant is only an
emergency repair, so you can drive to the next
workshop. The maximum permitted speed is
50 mph (80 km/h).
fDo not drive with tires whose tire pressure
drops again in a short period of time. In cases
of doubt, have tires checked by a specialist
workshop.
fIf the tire pressure monitoring system is
defective (e.g., defective wheel transmitter),
contact a specialist workshop immediately and
have the damages repaired.
The tire pressure will not be monitored by a
defective tire pressure monitoring system.fUse only the pressure differences shown in the
TYRE PRESSURE menu or from tire pressure
messages or warnings when correcting the
tire pressure.
fTires lose air over time without a tire defect
being present. A tire pressure warning will then
appear in the multi-purpose display.
Correct the tire pressure.
fThe tire pressure monitoring system gives a
warning about tire damages due to insufficient
tire pressure as well as about a gradual loss of
pressure due to foreign objects.
The tire pressure monitoring system cannot
warn you about tire damages occurring sud-
denly (e.g., flat tire due to sudden external ef-
fects).
fIf a message is displayed, check the tire
pressure at the next opportunity.
fBefore fitting tires approved by Porsche which
are not stored in the on-board computer, the
missing information should be supplemented
in the on-board computer.

Tire pressure screenIndication of tire pressures on the basic
screen "Tire pressure"
The basic screen "Tire pressure" shows the cur-
rent actual values of the tire pressures. These val-
ues would be identical to those of a pressure gage
connected to the four valves. These pressures
change while the vehicle is being driven.
– The tire pressures increase as the temperature
in the tires rises, e.g. during high-speed high-
way driving.
– The tire pressures decrease as the tempera-
tures drop, e.g. during trips in cold regions
(such as mountains).
The pressure changes by around 1.5 psi (0.1 bar)
for a temperature change of 50°F (10°C).The values displayed on the basic screen there-
fore do not allow conclusions to be drawn about
possible pressure deviations.
fUse only the pressure differences shown in the
TYRE PRESSURE menu or from tire pressure
messages or warnings when correcting the
tire pressure.
Filling informationTire pressure menu
MAIN MENU > TYRE PRESSURE
(only when vehicle is stationary)
Deviations in the tire pressures from the required
pressure are shown in the TYRE PRESSURE menu
(filling information). The tire pressure monitoring
system takes this relationship between tyre pres-
sure and temperature into account.
A “–” in front of the value indicates a pressure loss.
fThe tire pressures must be adjusted to the re-
quired pressure.
Example: If the tire pressure display shows
“–3 psi”, you must increase the tire pressure by
3psi.

System learning phaseEach time a wheel is changed, the tire pressure
monitoring system re-learns the tires. The system
identifies the wheel positions.
The current tire pressures will not be available on
the multi-purpose display until the learning phase
is complete.
System learning phase
fSelect tire type and tire size in the menu TYRE
PRESSURE > SETTINGS > TYRES.
The learning process is started. The tire type
and size m ust b e sele cte d even if the se tting s
for the new set of wheels are the same as for
the old wheels.Note
The spare wheel and collapsible spare wheel do
not contain a wheel transmitter and are not
monitored by the tire pressure monitoring system.
The tire pressures for cold tires (68 °F/20 °C) are
shown in the TYRE PRESSURE menu (filling infor-
mation) during the learning phase. The required
pressure for the spare wheel is always displayed
in the TYRE PRESSURE menu (filling information).
fCheck the tire pressure for the spare wheel
and collapsible spare wheel manually.
Tire pressure menuMAIN MENU > TYRE PRESSURE
The TYRE PRESSURE menu provides an overview
of the current pressure specifications for the
respective wheel (filling information). The pressure
differences with respect to the required pressure
are specified.
If the wheels have not been learned, the current
pressures are unavailable.
The spare wheel is not monitored. The required
pressure is specified in brackets.
To make changes to the settings of the tire pres-
sure monitoring system, select SETTINGS in the
TYRE PRESSURE menu.

Warning!
Incomplete entries on the multi-purpose
display affect correct information of
warnings and messages.
fAfter one of the following actions, the settings
must be updated in the TYRE PRESSURE
menu:
– Changing a wheel
– Filling with tire sealant
– Adding air (after previous warning “Flat tyre”)
fPlease observe the chapter “SELECTION AF-TER WARNING” on Page 97.The following settings made in this menu serve as
the basis on which the tire pressure monitoring
system determines the correct pressure.
