TPC Tire pressure monitoringfPlease observe the chapter “TIRES, RIMS,
TRACKS” on Page 268.
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
Safety notes!
Despite the advantages offered by the tire
pressure monitoring, it is still the driver’s
responsibility to update the corresponding
settings 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
defective 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.
fDefective tires must be immediately replaced
by an authorized Porsche dealer.
Tire repairs are not permissible under any
circumstances.fIf the 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 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 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 monitoring cannot warn you
about tire damage that occurs suddenly (e.g.
flat tire due to abrupt external effects).

Tire pressure warnings
The tire pressure monitoring warns about loss in
pressure in two stages, depending on the amount
of pressure loss:
Stage 1 – Add air
(3 to 6 psi (0.2 to 0.4 bar) loss in pressure)
Stage 2 – Flat tire
(from 6 psi (0.4 bar) loss in pressure)
Stage 1 – Add air
The pressure in the tire is too low by 3 to 6 psi (0.2
to 0.4 bar).
Driving with insufficient tire pressure reduces the
road safety of the vehicle and destroys the tire and
wheel.
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 with vehicle
stopped and can be acknowledged.
The tire pressure warning light in the instrument
panel goes out when the tire pressure has been
corrected.Stage 2 – Flat tire
The pressure in the tire has dropped by more than
6 psi (0.4 bar). This significant pressure loss is a
danger to road safety.
fWhen the tire pressure warning has appeared
on the on-board computer, stop immediately at
a suitable location. Check the tire for signs of
damage. If necessary, fill in tire sealant and set
the correct tire pressure.
This tire pressure warning appears when driving
and can be acknowledged.
The tire pressure warning light in the instrument
panel goes out when the tire pressure has been
corrected.

Controls, Instruments
System learningThe tire pressure monitoring begins to “learn” the
wheels after a wheel change, wheel transmitter
replacement or update of the tire settings. During
this process, the tire pressure monitoring recog-
nizes the tires and their locations. The on-board
computer displayes the message “TPC inactive –
system learning”.
The 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 on-board-computer:
– The displays of the Tire pressure function of
the on-board computer shows lines.
– The required pressures for cold tires at 68°F
(20°C) are indicated in the Info pressure
display in the Tire pressure menu.
– Tire pressure warnings are issued without tire
pressure and position information (figure) as
soon as the vehicle’s own wheels have been
detected and the tire pressure warning light
has gone out.Position and pressure information is displayed as
soon as the tire pressure monitoring has assigned
the wheels identified as belonging to the vehicle to
the correct wheel positions.
The wheel learning process takes place
exclusively when the vehicle is being driven.
fManually check the tire pressure at all wheels
and correct the tire pressure to the required
value.
Changing a wheel and replacing tiresfNew wheels must be fitted with radio transmit-
ters for the tire pressure monitoring.
Before tires are changed, the battery charge
state of the wheel transmitters should be
checked at an authorized Porsche dealer.
fSwitch the ignition off when changing a wheel.
The tire settings on the on-board computer must
be updated after changing a wheel.
A message appears if the characteristics of the
new tires do not agree with the on-board computer
settings.
fUpdate the on-board computer settings when
the vehicle is stationary the next time.The warning light in the speedometer lights up:
– When a loss in pressure has been detected
– If the tire pressure monitoring is faulty
– When learning newly mounted wheels/wheel
sensors, as long as the vehicle’s own wheels
have not yet been recognized.
The tire pressure warning light in the instrument
panel goes out only when the cause of the fault
has been rectified.

No monitoringIn the event of faults the tire pressure monitoring
cannot monitor the tire pressure.
The warning light on the instrument panel lights up
and a corresponding message appears on the
on-board computer.
Monitoring is not active when:
– the tire pressure monitoring is faulty,
– wheel transmitters for the tire pressure
monitoring are missing,
– temporarily after changing a wheel (learning
phase),
– more than four wheel transmitters are
detected,
– there is external interference by other radio
sources, e.g. wireless headphones,
– tire temperatures are too high.

BOARD COMPUTER” on Page 114.

1. Required-pressure line
2. Warning stage 1 (from –3 to –6 psi
(–0.2 bar to –0.4 bar))
3. Warning stage 2 (from –6 psi (–0.4 bar))In accordance with physical principles, the air
pressure changes as the temperature changes.
The tire pressure increases or decreases by
around 1.5 psi (0.1 bar) for every 50°F (10°C)
change in temperature.
The tire pressure monitoring takes this relation-
ship between tire pressure and temperature into
account.
Tire pressure specificationsInformation on tire pressure for public roads can
be found in this Owner's Manual or on the tire-pres-
sure plate in the left door aperture.
These values apply to cold tires at 68°F (20°C).
