Whenever a tire pressure is changed, (tire rotation, tire replacement, spare tire, etc.) perform the Reset Procedure. Whenever the battery is disconnected, perform the Reset Procedure.
Do not perform the RESET procedure without first correcting the cause of the malfunction and checking and adjusting the pressure in all 4 tires. If you press the button when the tire pressures are incorrect, the Tire Inflation Monitoring system will not work properly and may not alert the driver when a tire is low.
The system completes the procedure by going through a relearn process while the customer drives the vehicle.
It takes 15 to 20 minutes to learn tire pressures in each of 3 speed ranges (15-40 MPH, 40-65 MPH, above 65 MPH). After about 60 minutes of driving across all speed ranges, the system will alert the driver if a tire is 12 psi different from the other 3 tires for 2-8 minutes.
Detection thresholds may be higher and detection times may be longer on rough roads, curves and at high speeds. The system is not capable of detection at speeds greater than 75 MPH.
