TPM checks the inflation pressures of the four mounted tires. The system notifies you if there is a significant loss of pressure in one or more tires.
TPMS Functional requirement
In order to assure the reliable reporting of a flat tire, the system must be reset while all tire inflation pressures are correct. Always use wheels with TPM electronics. Otherwise, the system may malfunction. Each time a tire inflation pressure has been corrected or a wheel or tire has been changed, reset the system.
TPMS System limitations
TPM cannot warn you in advance of sudden severe tire damage caused by out- side influences.
The system does not work correctly if it has not been reset; for example, a flat tire may be indi- cated even though the tire inflation pressures are correct.
The system is inactive and cannot indicate a flat tire if a wheel without TPM electronics, such as a compact spare wheel, has been mounted, or if TPM is temporarily malfunctioning due to other systems or devices using the same radio frequency.
TPMS Status indicator on the Control Display
The color of the tires represents the status of the tires and the system. TPM takes into account that tire pressures change while the vehicle is being driven. The tire pressures do not need to be corrected unless the TPM instructs you to do so by means of color indicators.
The tire inflation pressure corresponds to the established target value. “TPM active” appears on the Control Display.
One wheel yellow
There is a flat tire or substantial loss of tire pres- sure in the indicated tire. A message appears on the Control Display.
All wheels yellow :
There is a flat tire or substantial loss of tire pressure in several tires. A message appears on the Control Display.
The system cannot detect a puncture. Possible reasons for this:
TPM is being reset
Temporary malfunction caused by systemsor devices using the same radio frequency
