   Start from the driver side front tire, remove the valve cap, and then increasing or decreasing the tire’s air pressure until a horn chirp sounds

   A horn chirp will confirm that the sensor has been reset

5. Turn off the ignition after you reset the last tire

   The TIRE LEARNING ACTIVE message will disappear

6. Adjust the tire pressure in all four tires recommended on the tire placard
