them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation also re-
duces fuel efficiency and tire tread life, and may af-
fect the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re-
sponsibility to maintain correct tire pressure, even if
under-inflation has not reached the level to activate
the TPMS tire pressure warning light. The display as
well as the settings for the Tire Pressure Monitoring
System take place on the multifunction display.
However, the tires still have to be inflated manually.

Please see chapter "Technical Data" on
page 334.
The TPMS offers the following functions:
– Permanent monitoring of tire pressure and tire
temperature.
– Displays the actual tire pressure (actual pres-
sure) during the trip.
– Tire pressure warnings in two stages (yellow and
red warning).
– Vehicle stationary: Display of pressure difference
The tire pressure warning light and a corre-
sponding message on the instrument cluster warn
against loss of pressure in two stages (yellow and
red tire pressure warning, depending on the extent
of the pressure loss).
The tire pressure warning light only goes out when
the tire pressure has been corrected to the set
pressure.
The yellow tire pressure warning is displayed for
around 10 seconds after the car comes to a stand-
still and the ignition has been switched off or when
the ignition is switched on again. The yellow tire
pressure warning can be acknowledged when the
ignition is switched on. The red tire pressure warning
also appears while traveling and can be
acknowledged.
e If the tire pressure warning light comes on and a
tire pressure warning is displayed even with a
correct tire pressure: Visit an authorized Porsche
dealer. Porsche recommends an authorized Por-
sche dealer, as they have trained technicians and
the necessary parts and tools.
Information
The tire pressure monitoring system issues warnings
relating to loss of pressure due to natural diffusion
and gradual loss of pressure caused by foreign
bodies. The Tire Pressure Monitoring System cannot
warn you about tire damage that occurs suddenly (e.
g. a flat tire due to unexpected external effects).
WARNING
Defective tires
Driving with defective tires can result in serious
accidents.
necessary parts and tools.
WARNING
High speed at comfort
pressure.
Excessive speed when comfort pressure is set dam-
ages the tires and wheels.
e Reduce speed to below the maximum speed
displayed in the instrument cluster.
e
For higher speeds, fill the tires to the standard
inflation pressure.
Malfunctions in the tire pressure monitoring
system
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is
not operating properly. The TPMS malfunction indi-
cator is combined with the tire pressure warning
light. When the system detects a malfunction, the
light indicator flashes for approximately one minute
and then remains continuously illuminated. This se-
quence will continue upon subsequent vehicle
e
When a red tire pressure warning appears on the
instrument cluster: Stop immediately in a suit-
able place and check the tires for damage. If
necessary, remedy the damage with tire sealant
or mount the spare wheel.
e Do not continue to drive with defective tires.
Have defective tires replaced immediately. Con-
sult an authorized Porsche dealer. Porsche rec-
ommends an authorized Porsche dealer, as they
have trained technicians and the necessary parts
and tools.
e
Do not drive with tires that repeatedly lose pres-
sure in a short space of time. If in doubt, have the
tire checked by an authorized Porsche dealer.
Porsche recommends an authorized Porsche
dealer, as they have trained technicians and the
in relation to the set pressure
flation pressure recommended by the vehicle man-
ufacturer on the vehicle placard or tire inflation
pressure label. (If your vehicle has tires of a different
size than the size indicated on the vehicle placard or
tire inflation pressure label, you should determine
the proper tire inflation pressure for those tires.) As
an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that causes a tire pressure warning light to
come on when one or more of your tires is signifi-
cantly under-inflated. Accordingly, when the tire
pressure warning light comes on, you should stop,
check your tires as soon as possible, and inflate
