Tires and wheels malfunction using the TPMS telltale flashing and illumination sequence. The telltale extinguishes after a few minutes driving if the malfunction has been corrected. Tire pressure inquiries are made using the multifunction display. The current tire inflation pressure for each tire appears in the multifunction display after a few minutes of driving. as the tire inflation pressure values cannot be allocated to the individual wheels, the message Tire Pressure Monitor Active appears. Despite this message, the tire inflation pressure values are monitored already. 225 i Possible differences between the readings of a tire pressure gauge of an air hose, e.g. gas station equipment, and the vehicle's control system can occur. The tire pressure displayed by the control system apply to sea level. In high-altitude locations, the reading on a tire pressure gauge will be higher than the reading issued by the vehicle's control system. Do not reduce the tire inflation pressure under such circumstances. X X i Operating radio transmission equipment (e.g. wireless headsets, two-way radios) in or near the vehicle could cause the TPMS to malfunction. i This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: 1. This device may not cause harmful interference, and 2. this device must accept any interference received, including interference that may cause undesired. Any unauthorized modification to this device could void the user's authority to operate the equipment. Tire inflation pressure warnings If the system detects a significant loss of tire inflation pressure in one or more than one tire, a message appears in the multifunction display. In addition, an acoustic warning sounds and the low tire pressure telltale in the instrument cluster comes on. Switch on the ignition. Press button V or U on the multifunction steering wheel repeatedly until the standard display appears in the multifunction display (Y page 122). X Press button & or * until the current inflation pressure for each tire appears in the multifunction display. Example illustration When the vehicle has been parked for longer than 20 minutes, the message Tire pressure displayed after driving for a few minutes. appears in the multifunction display. The TPMS recognizes new wheels or sensors automatically after the learn-in phase. As long Example illustration Z Operation i With a spare wheel mounted, the system may still indicate the tire inflation pressure of the removed road wheel for some minutes. If this happens, keep in mind that the indicated value where the spare wheel is mounted does not reflect the actual spare tire inflation pressure.
