How Temperature Affects Your TirePressure
The tire pressure monitoring systemmonitors tire pressure in each pneumatictire. While driving in a normal manner, atypical passenger tire inflation pressuremay increase about 2–4 psi (14–28 kPa)from a cold start situation. If the vehicle isstationary overnight with the outsidetemperature significantly lower than thedaytime temperature, the tire pressure maydecrease about 3 psi (21 kPa) for a drop of30°F (17°C) in ambient temperature. This
lower pressure value may be detected bythe tire pressure monitoring system asbeing significantly lower than therecommended inflation pressure andactivate the system warning light for lowtire pressure. If the low tire pressurewarning light is on, visually check each tireto verify that no tire is flat. If one or moretires are flat, repair as necessary. Checkthe air pressure in the road tires. If any tireis under-inflated, carefully drive the vehicleto the nearest location where air can beadded to the tires. Inflate all the tires tothe recommended inflation pressure.
TECHNICAL SPECIFICATIONS
Wheel Lug Nut Torque Specifications
WARNING
When a wheel is installed, always remove any corrosion, dirt or foreign materialspresent on the mounting surfaces of the wheel or the surface of the wheel hub,brake drum or brake disc that contacts the wheel. Make sure that any fastenersthat attach the rotor to the hub are secured so they do not interfere with the mountingsurfaces of the wheel. Installing wheels without correct metal-to-metal contact at thewheel mounting surfaces can cause the wheel nuts to loosen and the wheel to come offwhile your vehicle is in motion, resulting in loss of control.

*Torque specifications are for nut and bolt threads free of dirt and rust. Use only Fordrecommended replacement fasteners.
Retighten the lug nuts to the specified torque within 100 miles (160 kilometers) after anywheel disturbance (such as tire rotation, changing a flat tire, wheel removal).
