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:
fPlease 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, an d 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.
f 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.

f
Use only the pressure differences shown in the
“Fill info” display in the tire pressure menu or
from the corresponding tire pressure warning
when correcting the tire pressure.
f Tires can lose air over time without a tire
defect being present. A tire pressure warning
will then appear on the multi-function display.
Check the tire pressure at the next opportunity.
Warning!
Your vehicle has also been equipped with a TPM
malfunction indicator to in dicate when the system
is not operating properly.
The TPM malfunction indicator is combined with
the low tire pressure telltale.
When the system detects a malfunction, the
telltale will flash for approximately one minute and
then remain continuously illuminated. This
sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the
system may not be able to detect or signal low tire
pressure as intended.
TPM malfunctions may occur for a variety of
reasons, including the installation of replacement
or alternate tires or wheels on the vehicle that
prevent the TPM from functioning properly.
f Always check the TPM malfunction telltale after
replacing one or more tires or wheels on your
vehicle to ensure that the replacement or
alternate tires and wheels allow the TPM to continue to function properly. The warning light in the instrument panel lights up:
– When a loss in pressure has been detected.
– In the event of a defect in Tire Pressure
Monitoring or a temporary fault.
– When learning new fitted wheels/wheel transmitters, as long as the vehicle’s own
wheels have not ye t been recognized.
The tire pressure warning light on the instrument
panel goes out only when the cause of the fault
has been rectified.Warning light

correct tire pressure.
This tire pressure warning also appears when
driving and can be acknowledged.
The tire pressure warning light on the instrument
panel goes out only when the tire pressure has
been corrected.
System learningTire Pressure Monitoring begins to “learn” the
wheels after a wheel change, wheel transmitter
replacement or update of the tire settings . During
this process, Tire Pressu re Monitoring recognizes
the wheels and their locations.
The following message appears on the multi-
function display (example):
“No monitoring, system is learning”.
The wheel learning process takes place
exclusively when the vehicle is being driven
(vehicle speed above 16 mph (25 km/h)).
Tire Pressure Monitoring requires a certain
amount of time to learn the wheels. During this
time, the current tire pressures are not available
on the multi-function display:
– The tire pressure warning light remains lit until all wheels have been learned.
– Lines (-.-) appear on the display of the “Tire pressure” function. – The required pressures for cold tires (68 °F
(20 °C)) are indicated under “Fill info” in the tire
pressure menu.
Position and pressure information is displayed as
soon as Tire Pressure Monitoring has assigned
the wheels recognized as belonging to the vehicle
to the correct wheel positions.
f Check the tire pressure for all wheels under
“Fill info ”.
f Correct the tire pressure to the required
pressure if necessary.
Changing a wheel and replacing tiresfNew wheels must be fitted with radio
transmitters for Tire Pressure Monitoring.
Before tires are changed, the battery charge
condition of the wheel transmitters should be
checked.
Please contact a qualified specialist workshop.
We recommend that you have an authorized
Porsche dealer to do this work as they have
trained workshop personnel and the necessary
parts and tools.
f Switch off the ignition when changing a wheel.
The tire settings on the mu lti-function display must
be updated after changing a wheel.
If the tire settings are not updated, the message
“Tire change? Update settings!” is displayed on the
multi-function display.
f Update the multi-function display settings the
next time the vehicle is stationary.
Pressure increase as the result of
temperature increaseIn accordance with physical principles, the tire
pressure changes as the temperature
changes.The tire pressure increases or decreases
by 0.1 bar (1.5 psi) for
every 18 °F (10 °C) change in temperature.Partial monitoringMonitoring of the other wheels is continued if there
is a fault in one or two wheel transmitters.
– The tire pressure warning light lights up.
– The message “Restricted monitoring” appears
