Vehicle care 177■ The TPMS sensor matchingprocess was not done or notcompleted successfully afterrotating the tyres. The malfunctionlight and the warning message orcode should go off aftersuccessfully completing the sensormatching process. See "TPMSSensor Matching Process" later inthis section.■ One or more TPMS sensors aremissing or damaged. The warningmessage or code and themalfunction light should go offwhen the TPMS sensors areinstalled and the sensor matchingprocess is performed successfully.Consult your workshop for service.■ Replacement tyres or wheels donot match the original equipmenttyres or wheels. Tyres and wheelsother than those recommendedcould prevent the TPMS fromfunctioning properly.■ Operating electronic devices orbeing near facilities using radiowave frequencies similar to theTPMS could cause the TPMSsensors to malfunction.If the TPMS is not functioningproperly, it cannot detect or signala low tyre condition. Consult yourworkshop for service if the TPMSmalfunction light and a warningmessage or code come on and stayon.TPMS Sensor MatchingProcessEach TPMS sensor has a uniqueidentification code. The identificationcode must be matched to a new tyre/wheel position after rotating the tyresor replacing one or more of the TPMSsensors. The TPMS sensor matchingprocess should also be performedafter replacing a spare tyre with aroad tyre containing the TPMSsensor.The malfunction light and the warningmessage or code should go off at thenext ignition cycle. The sensors arematched to the tyre/wheel positions,using a TPMS relearn tool, in thefollowing order: driver side front tyre,passenger side front tyre, passengerside rear tyre, and driver side rear.Consult your workshop for service orto purchase a relearn tool. There aretwo minutes to match the first tyre/wheel position, and five minutesoverall to match all four tyre/wheelpositions. If it takes longer, thematching process stops and must berestarted.The TPMS sensor matching processis:1. Apply the parking brake.2. Turn the ignition on.3. Use the MENU button on the turnsignal lever to select the VehicleInformation Menu in the DriverInformation Centre (DIC).4. Use the thumbwheel to scroll tothe tyre pressure menu.5. Press the SET/CLR button tobegin the sensor matchingprocess. A message requestingacceptance of the process shoulddisplay.
