TPMS Sensor Matching ProcessEach TPMS sensor has a unique identification code.Any time you replace one or more of the TPMS sensorsor rotate your vehicle's tires, the identification codes willneed to be matched to the new tire/wheel position. Thesensors are matched to the tire/wheel positions in thefollowing order: driver side front tire, passenger sidefront tire, passenger side rear tire, and driver side reartire using a TPMS diagnostic tool. See your dealer/retailer for service.The TPMS sensors may also be matched to each tire/wheel position by increasing or decreasing the tire's airpressure. When increasing the tire's pressure, do notexceed the maximum inflation pressure indicated on thetire's sidewall. If using this method to match TPMSsensors, the complete procedure outlined below mustbe performed within 15 minutes of the vehicle beingstationary.To decrease air-pressure out of a tire you can use thepointed end of the valve cap, a pencil-style air pressuregage, or a key.You will have one minute to match the first tire/wheelposition, and five minutes overall, to match all fourtire/wheel positions. If it takes longer than one minute tomatch the first tire and wheel, or more than five minutesto match all four tire/wheel positions, the matchingprocess stops and you will need to start over.The TPM matching process is outlined below:1. Set the parking brake.2. Press the push-button ignition switch to Acc.3. Using the keyless access transmitter, lock andunlock the vehicle's doors.4. Press the lock and unlock buttons, at the sametime, on the keyless access transmitter. The hornsounds twice, indicating that the TPMS is ready,and the sensor matching process can begin.5. Start with the driver side front tire.6. Remove the valve cap from the valve stem.Activate the TPMS sensor by increasing ordecreasing the tire's air pressure for five seconds,or until a horn chirp sounds. The horn chirp, whichmay take up to 30 seconds to sound, confirms thatthe sensor identification code has been matched tothis tire position.7. Proceed to the passenger side front tire, andrepeat the procedure in Step 6.8. Proceed to the passenger side rear tire, and repeatthe procedure in Step 6.9. Proceed to the driver side rear tire, and repeat theprocedure in Step 6.6-66
