Meaning/measure
The Tire Pressure Monitoring has detected a
gradual pressure loss. Correct tire pressure at
the next opportunity.
The Tire Pressure Monitoring is learning the
wheels on the vehicle. The Tire Pressure Moni-
toring is searching for the tires and their posi-
tion. During this period the current pressure
specifications are not available on the on-board
computer.
The Tire Pressure Monitoring is faulty.
Consult an authorized Porsche dealer.
1 or 2 wheel transmitters are faulty. The tyre
pressures of these wheels are not monitored.
The other wheels are still monitored.
Consult an authorized Porsche dealer.
The Tire Pressure Monitoring is temporarily de-
activated by excessive tire temperatures (ap-
prox. 248 °F (120 °C)) or external interference
(e.g. from other wheel transmitters inside the
car). Once the source of the interference is re-
moved, the system is automatically reactivated.
Update the settings in the TPM menu of the
on-board computer at the next opportunity.
Wrong entries will affect the correct pressure in-
formation in the menu. The safety of your vehi-
cle is at risk.
The display of the Tire Pressure Monitoring is
faulty.
Consult an authorized Porsche dealer.
