NOTE:
Tire Inflation Monitor (TIM) should be reset every time tire pressure is adjusted, tires are rotated, one or more tires are repaired or replaced, or battery has been disconnected.
System takes 15-20 minutes of driving in each of 3 speed ranges to learn tire pressure. Speed ranges are 15-40 MPH, 40-65 MPH and more than 65 MPH. When learning process is complete and after 2-8 minutes of driving, system will alert driver if a tire pressure difference of 12 psi is present in any one tire. Detection thresholds may be higher and detection times may be longer on rough roads, curves and at high speeds (more than 70 MPH).
