Tire PressureThe tire pressure monitoring system continuously
monitors tire pressure and tire temperature on all
four wheels and warns the driver when the tire
pressure is too low.
The display as well as the settings for tire
pressure monitoring are done on the multi-
purpose display 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, immediate-
ly 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.
Tyre repairs are not permissible under
any circumstances.
fSealing the tyre with the tyre 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 tyre 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 defec-
tive (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 tyre pressure
messages or warnings when correcting the
tyre pressure.
fTires lose air over time without a tire defect be-
ing 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 tyre damages due to insufficient
tyre pressure as well as about a gradual loss
of pressure due to foreign objects.
The tyre pressure monitoring system cannot
warn you about tyre damages occurring sud-
denly (e.g., flat tyre 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.

Tyre 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.
Tyre pressure menu (filling information)Tire pressure menu
MAIN MENU > TYRE PRESSURE
The TYRE PRESSURE menu can only be called up
when the 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 tire
pressure and temperature into account.
A “–” in front of the value indicates a pressure loss.
fThe tire pressures must be adjusted to the
required pressure.
Example: If the tire pressure display shows
“–3 psi (–0.2 bar)”, you must increase the tire
pressure by 3 psi (0.2 bar).

Tire pressure monitoring system learning
phaseEach time a wheel is changed, the tire pressure
monitoring system must complete the learning
phase again. The tire pressure monitoring system
identifies the wheel positions in this process.
The current tire pressures will not be available on
the multi-purpose display until the learning phase
is complete.
Tire pressure monitoring system learning
process
fSelect tire type and tire size in the menu TYRE
PRESSURE > SETTINGS > TYRES.
The learning process is started. The tire type
and size must be selected even if the settings
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 moni-
tored 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 al-
ways displayed in the TYRE PRESSURE menu (fill-
ing information).
fCheck the tire pressure for the spare wheel
and collapsible spare wheel manually.
Tire pressure filling informationTire pressure menuThe TYRE PRESSURE menu provides an overview
of the current pressure specifications for the re-
spective wheel (filling information). The pressure
differences with respect to the required pressure
are specified irrespective of the tire temperature.
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.
