Operation Tires and wheels Tire inflation 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. Restarting the TPMS Warning! TPMS malfunctions may occur for a variety of reasons, including the installation of incompatible replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly. G It is the driver's responsibility to calibrate the TPMS on the recommended cold inflation pressure. Underinflated tires affect the ability to steer or brake the vehicle. You might lose control over the vehicle. i If a condition causing the TPMS to malfunction develops, it may take up to 10 minutes for the system to signal a malfunction using the TPMS telltale flashing and illumination sequence. The telltale extinguishes after a few minutes driving if the malfunction has been corrected. Example illustration In addition, a warning signal sounds. The TPMS must be restarted when you have adjusted the tire inflation pressure to a new level (e.g. because of different load or driving conditions). The TPMS is then recalibrated to the current tire inflation pressures. Using the Tire and Loading Information placard on the driver's door B-pillar ( page 296) or, if available, the supplemental tire inflation pressure information on the inside of the fuel filler flap ( page 283), make sure the tire inflation pressure of all four tires is correct. i Operating radio transmission equipment (e.g. wireless headsets, two-way radios) in or near the vehicle could cause the TPMS to malfunction. 308
