BMW X3 Owners Manual: The concept
The system monitors tire inflation pressure in the four mounted tires. The system warns you if there is a significant loss of pressure in one or more tires. For this purpose, sensors in the tire valves measure the tire inflation pressure and tire temperature.
Hints
Tire damage due to external factors
Sudden tire damage caused by external circumstances cannot be recognized in advance.
With use of the system observe further information found under Tire inflation pressure.
Functional requirements
The system must have been reset with the correct tire inflation pressure; otherwise, reliable signaling of tire inflation pressure loss is not assured.
Reset the system after each adjustment of the tire inflation pressure and after every tire or wheel change.
Always use wheels with TPM electronics to ensure that the system will operate properly.
