9. The driver side rear turn signal comes on to indicate that corner sensor is ready to be learned. Proceed to the driver side rear tire, and repeat the procedure in Step 6. 10. After hearing the single horn chirp for the driver side rear tire, two additional horn chirps sound to indicate the tire learning process is done. The LEARN COMPLETE message displays if all four tire positions are learned. Turn the ignition switch to LOCK/OFF. If no tires are learned after entering the TPMS learn mode, or if communication with the receiver stops, or if the time limit has expired, the TIRE LEARN? message displays on the DIC. Turn the ignition switch to LOCK/OFF and start over beginning with Step 2. 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 the vehicle's tires, including the spare tire, if the vehicle has one, for signs of wear or damage. See When It Is Time for New Tires on page 6‑73 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 7‑3 . If this vehicle has P225/40R18 size tires, they should be rotated every 3,000 miles (5 000 km). The purpose of a regular tire rotation is to achieve a uniform wear for all tires on the vehicle. This will ensure that the vehicle continues to perform most like it did when the tires were new. Any time you notice unusual wear, rotate the tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. See When It Is Time for New Tires on page 6‑73 and Wheel Replacement on page 6‑77 . 6-71
