Controls Reference Mobility Communications Entertainment Navigation Driving tips The concept Functional requirement In order to assure the reliable reporting of a flat tire, the system must be reset at the correct tire inflation pressure. Always use wheels with TPM electronics, otherwise fault-free operation of the system is not ensured. Reset the system again after each correction of the tire inflation pressure and after every tire or wheel change.< System limits "resetting FTM ..." is displayed for a few seconds. The warning lamp in the instrument cluster lights up yellow for a few seconds. 9. Start to drive. The initialization finishes during driving without feedback. TPM cannot announce sudden serious tire damage caused by external influences. The system does not function properly if it has not been reset, e.g. a flat tire is reported despite correct tire inflation pressures. The system is inactive and cannot display a flat tire if a wheel has been mounted without TPM electronics, or if TPM is temporarily interfered with by other systems or devices which use the same radio frequency. Indication of a flat tire The warning lamp lights up red. A message appears on the Control Display. In addition, an acoustic signal sounds. There is a flat tire or extensive inflation pressure loss. 1. Reduce speed and stop the vehicle carefully. Avoid sudden braking and steering maneuvers. 2. Identify damaged tire. To do this, check the tire inflation pressure using the M Mobility System, refer to Producing tire inflation pressure on page 227. Status display on Control Display The tire and system status is indicated by the color of the tires. TPM takes the fact that the tire pressure changes during driving into account. A correction is only required if requested by TPM with the color. Green The tire pressure matches the learned set state. 85 Online Edition for Part no. 01 41 2 600 738 - © 08/08 BMW AG At a glance
