  5. Starting with left front tire, follow either of these 2 procedures:
    • Increase/Decrease Method:  Increase or decrease tire pressure for 8-10 seconds, then wait for the horn to make a chirp sound. The horn chirp may occur before the 8-10 second pressure increase/decrease time period has been reached, or up to 30 seconds after the 8-10 second pressure increase/decrease time period has been reached
    • Sensor Activation Tool Method:  Starting with the left front tire, hold the activation tool against the tire wall aiming upward with the antenna. Press the activate button and wait for a horn chirp.
