6. Remove the valve cap from the valve cap stem. Activate the TPMS sensor by increasing or decreasing the tire's air pressure for five seconds, or until a horn chirp sounds. The horn chirp, which may take up to 30 seconds to sound, confirms that the sensor identification code has been matched to this tire and wheel position. 7.

Proceed to the driver side rear tire, and repeat the procedure in Step 6. 10. After hearing the confirming horn chirp for the driver side rear tire, the tire sensor matching process ends. Turn the ignition switch to LOCK. 11. Set all four tires to the recommended air pressure level as indicated on the Tire and Loading Information label. 12. Put the valve caps back on the valve stems. Tire Inspection and Rotation We recommend that you regularly inspect your vehicle's tires, including the spare tire, for signs of wear or damage. See When It Is Time for New Tires on page 5-64 for more information. Tires should be rotated every 5,000 to 8,000 miles (8 000 to 13 000 km). See Scheduled Maintenance on page 6-4. The purpose of a regular tire rotation is to achieve a uniform wear for all tires on the vehicle. This will ensure that your vehicle continues to perform most like it did when the tires were new. Any time you notice unusual wear, rotate your tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels.
