Engine-mounted Fuel Filter
Although the fuel system is not fullypressurized when the vehicle is off, someresidual pressure may remain in the fuelsystem since it can take some time for thepressure to completely bleed off.Therefore, we recommend you place anabsorbent cloth below the filter connectorsto absorb any fuel that may drain.
The engine-mounted fuel filter is a plasticdisposable cartridge.
Removal
1.Disconnect the fuel lines by squeezingthe connector tabs and pulling the linesstraight off.

USING SNOW CHAINS
WARNING
Snow tires must be the same size,load index, speed rating as thoseoriginally provided by Ford. Use ofany tire or wheel not recommended byFord can affect the safety andperformance of your vehicle, which couldresult in an increased risk of loss of vehiclecontrol, vehicle rollover, personal injury anddeath. Additionally, the use ofnon-recommended tires and wheels couldcause steering, suspension, axle, transfercase or power transfer unit failure.
Note:Do not use snow chains on vehicleswith 20 inch wheels and tires.
The tires on your vehicle have all-weathertreads to provide traction in rain and snow.However, in some climates, you may needto use snow tires and cables. If you needto use cables, it is recommended that steelwheels (of the same size andspecifications) be used, as cables may chipaluminum wheels.
Note:The suspension insulation andbumpers will help prevent vehicle damage.Do not remove these components from yourvehicle when using snow tires and chains.
Follow these guidelines when using snowtires and chains:
•If possible, avoid fully loading yourvehicle
•Use only SAE Class S chains.
•Install chains securely, verifying thatthe chains do not touch any wiring,brake lines or fuel lines.
•Drive cautiously. If you hear the chainsrub or bang against your vehicle, stopand retighten the chains. If this doesnot work, remove the chains to preventdamage to your vehicle.
•Remove the tire chains when they areno longer needed. Do not use tirechains on dry roads.
If you have any questions regarding snowchains or cables, please contact yourauthorized dealer.
TIRE PRESSURE MONITORING
SYSTEM
Vehicle Tire Pressure MonitoringSystem
WARNING
The tire pressure monitoring systemis not a substitute for manuallychecking tire pressures. You shouldperiodically check tire pressures using apressure gauge. Failure to correctlymaintain tire pressures could increase therisk of tire failure, loss of control, vehiclerollover and personal injury.
Each tire, including the spare (ifprovided), should be checkedmonthly when cold and inflatedto the inflation pressure recommended bythe vehicle manufacturer on the vehicleplacard or tire inflation pressure label. (Ifyour vehicle has tires of a different sizethan the size indicated on the vehicleplacard or tire inflation pressure label, youshould determine the proper tire inflationpressure for those tires.)

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 the vehicle is in motion, resulting in loss of control.
lb.ft (Nm)Bolt size
165 lb.ft (224 Nm)M14 x 1.5
*Torque specifications are for nut and bolt threads free of dirt and rust. Use only Fordrecommended replacement fasteners.
On vehicles equipped with single rear wheels, retighten the lug nuts to the specified torqueat 100 miles (160 kilometers) after any wheel disturbance (such as tire rotation, changinga flat tire, wheel removal).
On vehicles equipped with dual rear wheels, retighten the wheel lug nuts to the specifiedtorque at 100 miles (160 kilometers), and again at 500 miles (800 kilometers) of newvehicle operation and after any wheel disturbance (such as tire rotation, changing a flattire, wheel removal).
It is important to follow the proper wheel mounting and lug nut torque procedures.
On all two-piece flat wheel nuts, apply one drop of motor oil between the flat washerand the nut. Do not apply motor oil to the wheel nut threads or the wheel stud threads.
