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:
▷ If a wheel without TPM electronics is
mounted, e.g., compact wheel.
▷ When the TPM is disturbed by other systems
or devices with the same radio frequency.
