Tire PressurefPlease observe the chapter “TIRES/WHEELS”
on Page 297.
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.

System learning phaseEach time a wheel is changed, the tire pressure
monitoring re-learns the tires. The system identi-
fies 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 TIRE
PRESSURE > SETTINGS > TIRES.
The learning process is started. The tire type
and size must be selected e ve n if the se ttings
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.
The tire pressures for cold tires (68 °F/20 °C) are
shown in the TIRE PRESSURE menu (filling informa-
tion) during the learning phase. The required
pressure for the spare wheel is always displayed
in the TIRE PRESSURE menu (filling information).
fCheck the tire pressure for the spare wheel
and collapsible spare wheel manually.
Tire pressure menuMAIN MENU > TIRE PRESSURE
The TIRE 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.

sure monitoring, select SETTINGS in the TIRE

Speed limits for tires
Danger!
Risk of accident due to excessive speed.
This could lead to severe personal injury or
death.
fAlways observe the permissible maximum
speed of the respective tire.
fExceeding maximum tire speed could result in
a tire burst, causing lose of control of the vehi-
cle. This could lead to severe personal injury or
death.
Moreover, Porsche recommends obeying all
traffic laws at all times to maintain the safety of yourself and all vehicle occupants.
The speed code letter indicates the maximum per-
missible speed for the tire.
