When the tire pressure warning has appe ared
on the on-board computer, stop immediately at
a suitable location. Che c k the tire for s i gns 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 p anel goes out when
the tire pressure ha s been corrected.
System l earning
The Tire Pressure Mon itoring begins to “learn” the
wheels after a wheel change, wheel transmitter
replacemen t or update of the tire settings. Durin g
this proce ss, the Tire Pressure Monitoring recog-
nizes the tires and thei r locations. The on-board
computer displ ayes the message “TPC inactive -
system learni ng”.
The Tire Pressure Monitoring requires a certain
amou n t of time to learn the wheels. D uring this
time, the current tire pressures are not available on
the on-board-computer:
– The display of the Tire pressure functio n of the
on-board computer s hows lines.
– The requi red 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 (gure) as
soon as the vehic le’s own wheels have been
detected and the tire press ure warning li ght
has gone out.
Position and pressure information is displayed as
soon as the Tire Pressure Monitoring ha s assigned
the wheels id entified as bel onging to the vehicle to
the c orrect wheel positio ns.
The wheel learning process takes place exclusively
when the vehicle is being driven.
Manually check the tire pressure at all wheels
and correct the tire pressure to the required
value.
Changing a wheel and replaci ng t ires
New wheels must be fitted with radio transm it-
ters for the Tire Pressure Monitoring. Before
tires are changed, the batte ry charge state of
the w heel transmitters should be checked at
an authorized Porsche deal er.
Switch the ignition off when changing a wheel.
The t ire settings o n 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 .
Update the on-board computer settings when
the v ehicle is stationary the next time.
Warning light
The warning light in the speedometer lights up :
– When a loss in pressure has been detected
– If the Tire Pressure Mon itoring 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 instr ument
panel goes out only when the cause of the fault has
been rectifi ed.
