Tire Pressure Monitor TPM
The concept
The tire inflation pressure is measured in the four mounted tires. The system notifies you if there is a significant loss of pressure in one or more tires.
Functional requirements
The system must have been reset when the inflation pressure was correct; otherwise, reliable signaling of a flat tire is not ensured. Always use wheels with TPM electronics to ensure that the system will operate properly. Reset the system after each correction of the tire inflation pressure and after every tire or wheel change.
System limits
Sudden tire damage
Sudden serious tire damage caused by
external influences cannot be indicated in advance.◀
The system does not operate correctly if it has not been reset. For example, a flat tire may be indicated despite correct tire inflation pressures.
The system is inactive and cannot indicate a flat tire:
▷ For a mounted wheel without TPM electronics.
▷ When the TPM is disturbed by other systems
or devices with the same radio frequency.
Status display
Status display The current status of the Tire Pressure Monitor TPM can be displayed on the Control Display, e.g., whether or not the TPM is active.
