Tire PressurefPlease observe the chapter “TIRES/WHEELS”

The tire pressure monitoring monitors the pres-
sure 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 TIRE 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 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 risk of a tire failure and resulting
loss of control. Furthermore, low tire pres-
sure increases rate of wear of the affected
tires.
Despite the advantages offered by the tire
pressure monitoring, it is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pres-
sure, even if under-inflation has not reached
the level to trigger illumination of the tire
pressure monitoring low tire pressure mes-
sage.
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 repair shop.
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
repair shop. 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 re-
pair shop.
fIf the tire pressure monitoring is defective
(e.g., defective wheel transmitter), contact a
specialist repair shop immediately and have
the damages repaired.
The tire pressure will not be monitored by a
defective tire pressure monitoring.
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 at the next opportunity.
fThe tire pressure monitoring 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 cannot warn you
about tire damages occurring suddenly (e.g.,
flat tire due to sudden external effects).
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 the pressure differences shown in the TIRE
PRESSURE menu or from tire pressure mes-
sages or warnings when correcting the tire
pressure.
Filling informationTire pressure menu display
MAIN MENU > TIRE PRESSURE
(only when vehicle is stationary)
Deviations in the tire pressures from the required
pressure are shown in the TIRE PRESSURE menu
(filling information). The tire pressure monitoring
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 re-
quired pressure.
Example: If the tire pressure display shows
“–3 psi”, you must increase the tire pressure by
3psi.

Tire pressure warnings and
messagesThe tire pressure monitoring warns about loss in
pressure in two stages, depending on the amount
of pressure loss:
Stage 1 – Tire pressure too low message
(3 to 6 psi (0.2 to 0.4 bar) loss in pressure)
Stage 2 – Flat tire warning
(loss in pressure as of 6 psi (0.4 bar))
Warning!
Risk of accident. Tire damage may impair
road safety.
fStop the vehicle in a suitable place. Check the
tires for signs of damage and change them if necessary.
Example: If the tire pressure display shows
„– 3 psi“, you must increase the tire pressure by
3psi.
Tires lose air over time without a tire defect being
present. The tire pressure monitoring will then
issue a corresponding message or warning.
