Changing Tires With a Tire Understanding Your Tire Pressure Pressure Monitoring System Monitoring System The tire pressure monitoring system measures pressure in your four road tires and sends the tire pressure readings to your vehicle. The low tire pressure warning light will turn on if the tire pressure is significantly low. Once the light is illuminated, your tires are under-inflated and need to be inflated to the manufacturer’s recommended tire pressure. Even if the light turns on and a short time later turns off, your tire pressure E142549 still needs to be checked.
Note: Each road tire is equipped with a tire When Your Temporary Spare Tire is pressure sensor located inside the wheel Installed and tire assembly cavity. The pressure sensor is attached to the valve stem. The When one of your road tires needs to be pressure sensor is covered by the tire and is replaced with the temporary spare, the not visible unless the tire is removed. Take system will continue to identify an issue to care when changing the tire to avoid remind you that the damaged road wheel damaging the sensor and tire assembly needs to be repaired and put back on your vehicle. You should always have your tires serviced by an authorized dealer. To restore the full function of the tire pressure monitoring system, have the Check the tire pressure periodically (at damaged road wheel and tire assembly least monthly) using an accurate tire repaired and remounted on your vehicle. gauge. See Inflating Your Tires in this chapter. When You Believe Your System is Not Operating Properly The main function of the tire pressure monitoring system is to warn you when your tires need air. It can also warn you in the event the system is no longer capable of functioning as intended. See the following chart for information concerning your tire pressure monitoring system:
