Tire Pressure Monitoring (TPM)
Each tire should be checked monthly when cold
and inflated to the inflation pressure
recommended by Porsche on the tire inflation
pressure label.
For information on the tire inflation pressure label:
f
Please see the chapter “TIRES AND WHEELS”
on page 280.
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPM) that illuminates a low tire pressure telltale
(warning light) when one or more of your tires is
significantly under-inflated.
Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires
as soon as possible, and inflate them to the
proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can
lead to tire failure. Under-inflation also reduces
fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
However, the tire pressure must still be set
manually on the wheel.

Please see the chapter “TIRE PRESSURE FOR
COLD TIRES (68 °F/20 °C)” on page 326.
Danger!
Risk of serious personal injury or death.
Driving the vehicle with low tire pressure
increases the risk of a tire failure and
resulting loss of control. Furthermore, low
tire pressure increases rate of wear of the
affected tires.
Please note that the Tire Pressure Monitoring
is not a substitute for proper tire
maintenance, and it is the driver's
responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of
Tire Pressure Monitoring low tire pressure
telltale. Low tire pressure reduces the road
safety of the vehicle and destroys the tire and
wheel.
Tire Pressure Monitoring gives a warning
about tire damage caused by a natural loss
in pressure as well as about a gradual loss of
pressure caused by foreign objects.
Tire Pressure Monitoring cannot warn you
about tire damage that occurs suddenly (e.g.
flat tire due to abrupt external effects).
f
When a red tire pressure warning appears,
stop immediately in a suitable place and check
the tires for damage. If necessary, remedy the
damage with a tire sealant.
f
Do not by any means continue to drive with
defective tires.
f
Sealing the tire with tire sealant is only an
emergency repair so you can drive to the
nearest specialist workshop.
The permitted top speed is
50 mph
(80 km/h)
.
f
Do not drive with tires in which the tire
pressure drops again very quickly. In case of
doubt, have tires checked by a specialist
workshop.
f
Defective tires must be replaced immediately
at an authorized Porsche dealer.
Tires must never be repaired under any
circumstances.
f
If Tire Pressure Monitoring is defective
(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 when Tire
Pressure Monitoring is defective.
For information on warning messages on the multi-
function display:
f
Please see the chapter “OVERVIEW OF
WARNING MESSAGES” on page 152.
f
Incomplete entries or selection of the wrong
tires on the multi-function display affect the
accuracy of warnings and messages.
The settings in the tire pressure menu must be
updated following a wheel change or changes
in vehicle loading.
