Maintenance and Specifications The tire pressure monitoring system is NOT a substitute for manually checking tire pressure. The tire pressure should be checked periodically (at least monthly) using a tire gauge, see Checking the tire pressure in this chapter. Failure to properly maintain your tire pressure could increase the risk of tire failure, loss of control, vehicle rollover and personal injury. Changing tires with TPMS It is recommended that you always have your tires serviced by a dealer or qualified technician. Each tire is equipped with a tire pressure sensor mounted on the wheel inside the tire behind the valve stem. The tire pressure sensor must be unbolted from the wheel prior to tire removal. The sensor can be removed by loosening the nut at the valve stem. Failure to remove the sensor may damage it. The rubber grommet (washer) between the wheel and the tire pressure sensor needs to be replaced when any tire is changed to minimize air leaks. The tire pressure should be checked periodically (at least monthly) using a tire gauge, refer to Checking the tire pressure in this chapter. SNOW TIRES AND CHAINS Snow tires must be the same size and grade as the tires you currently have on your vehicle. The tires on your vehicle have all weather treads to provide traction in rain and snow. However, in some climates, you may need to use snow tires and chains. Follow these guidelines when using snow tires and chains: • Use only cable type chains or chains offered by Ford as an accessory or equivalent. Other conventional link type chains may contact and cause damage to the vehicle's wheel house and/or body. 336
