Tire Pressure MonitoringfPlease see the chapter “TIRE PRESSURES FOR
COLD TIRES (68 °F / 20 °C)” on Page 289.
The Tire Pressure Monitoring 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 the Tire
Pressure Monitoring take place on the on-board
computer.
However, you must still adjust the tire pressure on
the wheel.fThe driver is responsible for filling the tires
correctly and making the correct settings on
the on-board computer.
The Tire Pressure Monitoring offers the following
functions:
– Display of the actual tire pressure while the
vehicle is in motion.
– Display of the deviation from the required
pressure (refilling pressure).
– Display of currently set tire size and type.
– Tire pressure warnings in two stages.
Warning!
fDespite the advantages offered by the Tire
Pressure Monitoring, it is still the driver’s re-
sponsibility to update the corresponding set-
tings in the on-board computer and maintain
the pressure in the tires.
Low tire pressure reduces the road safety of
the vehicle and destroys the tire and wheel.
fWhen a flat tire has been displayed, immedi-
ately stop in a suitable place and check the
tires for damage. If necessary, remedy the
damage with a tire sealant.
fDo not by any means continue to drive with
damaged tires.
fSealing the tire with tire sealant is only an
emergency repair, so you can drive to the next
authorized Porsche dealer. The maximum per-
mitted 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 an authorized
Porsche dealer.
fDamaged tires must be immediately replaced
by an authorized Porsche dealer.
Tire repairs are not permissible under any
circumstances.
fIf a fault occurs in the Tire Pressure Monitoring
(e.g. defective wheel transmitter), contact an
authorized Porsche dealer immediately and
have the damage repaired.
The tire pressure will not be monitored at all or
will be monitored only partially by defective
Tire Pressure Monitoring.
fTires lose air over time without a tire defect
being present. A tire pressure warning will then
appear in the on-board computer display.
Correct the tire pressure at the next oppor-
tunity.
fThe Tire Pressure Monitoring gives a warning
about tire damage due to natural pressure loss
as well as about a gradual loss of pressure due
to foreign objects.
The Tire Pressure Mnitoring cannot warn you
about tire damage that occurs suddenly (e.g.
flat tire due to abrupt external effects).

fSelect arrow (Back) and push the operating
lever forward. The display returns to the tire
pressure menu.
The on-board computer additionally displays
the message “System learning”.Note
The message “Process aborted” appears if the
setting process is interrupted. All entries made up
to this point are lost, and the original settings
remain in effect.
Only if the message “Process complete” appears
after the settings have been made will the Tire
Pressure Monitoring re-learn the wheels.
fPlease see the chapter “SYSTEM LEARNING”
on Page 150.
Before fitting tires with sizes which are not stored
in the on-board computer, the missing information
should be supplemented in the on-board
computer.
fPlease consult your authorized Porsche
dealer.
fUse only tires approved by Porsche.
The available items in the tire pressure menu
depend on the tires on your vehicle. For this
reason it is possible that some of the items shown
here are not available on your on-board
computer’s display.
fMake sure that tire pressures correspond to
the on-board computer settings. Correct the
tire pressure if necessary.

fMake sure that the tire pressures correspond
to the on-board computer settings. Correct the
tire pressures if necessary.Tire pressure warnings
The tire pressure warning light on the instrument
panel and a corresponding message on the on-
board computer warn about loss of pressure in
two stages, depending on the amount of pressure
loss.
Driving with insufficient tire pressure reduces the
road safety of the vehicle and destroys the tire and
wheel.
Stage 1 – Add air
The pressure in the tire is too low by 4 to 7 psi (0.3
to 0.5 bar).
fThe tire pressure warning contains the
affected tire with the tire pressure to be added.
Correct the tire pressure at the next
opportunity. This tire pressure warning appears
– for approx. 10 seconds with vehicle stopped
when switching off the ignition or
– again when switching on the ignition.
With ignition on, the warning can be deactivated.
The tire pressure warning light in the instrument
panel goes out only when the tire pressure has
been corrected.
