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. Thislower 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.
CHANGING A ROAD WHEEL
WARNINGS
Do not use tire sealants as they maydamage the tire pressure monitoringsystem.
If the tire pressure monitor sensorbecomes damaged it may notfunction.
Note:The tire pressure monitoring systemindicator light will illuminate when the sparetire is in use. To restore the full function ofthe monitoring system, all road wheelsequipped with tire pressure monitoringsensors must be mounted on the vehicle.
If you get a flat tire while driving, do notapply the brake heavily. Instead, graduallydecrease your speed. Hold the steeringwheel firmly and slowly move to a safeplace on the side of the road.
Have a flat serviced by an authorizeddealer in order to prevent damage to thetire pressure monitoring system sensors.See Tire Pressure Monitoring System(page 287). Replace the spare tire with aroad tire as soon as possible. Duringrepairing or replacing of the flat tire, havethe authorized dealer inspect the tirepressure monitoring system sensor fordamage.
Dissimilar Spare Wheel and TireAssembly Information
WARNING
Failure to follow these guidelinescould result in an increased risk ofloss of vehicle control, injury or death.
If you have a dissimilar spare wheel andtire, then it is intended for temporary useonly. This means that if you need to use it,you should replace it as soon as possiblewith a road wheel and tire assembly thatis the same size and type as the road tiresand wheels that were originally providedby Ford. If the dissimilar spare tire or wheelis damaged, it should be replaced ratherthan repaired.
A dissimilar spare wheel and tire assemblyis defined as a spare wheel and tireassembly that is different in brand, size orappearance from the road tires and wheelsand can be one of three types:
1.T-type mini-spare: This spare tirebegins with the letter T for tire size andmay have Temporary Use Only molded inthe sidewall.

2.Full-size dissimilar spare with labelon wheel: This spare tire has a label onthe wheel that states: THIS WHEEL ANDTIRE ASSEMBLY FOR TEMPORARY USEONLY.
When driving with one of the dissimilarspare tires listed above, do not:
•Exceed 50 mph (80 km/h).
•Load the vehicle beyond maximumvehicle load rating listed on the SafetyCompliance Label.
•Tow a trailer.
•Use snow chains on the end of thevehicle with the dissimilar spare tire.
•Use more than one dissimilar spare tireat a time.
•Use commercial car washingequipment.
•Try to repair the dissimilar spare tire.
Use of one of the dissimilar spare tireslisted above at any one wheel location canlead to impairment of the following:
•Handling, stability and brakingperformance.
•Comfort and noise.
•Ground clearance and parking at curbs.
•Winter weather driving capability.
•Wet weather driving capability.
•All-wheel driving capability.
3.Full-size dissimilar spare withoutlabel on wheel
When driving with the full-size dissimilarspare wheel and tire assembly, do not:
•Exceed 70 mph (113 km/h).
•Use more than one dissimilar sparewheel and tire assembly at a time.
•Use commercial car washingequipment.
•Use snow chains on the end of thevehicle with the dissimilar spare wheeland tire assembly.
The usage of a full-size dissimilar sparewheel and tire assembly can lead toimpairment of the following:
•Handling, stability and brakingperformance.
•Comfort and noise.
•Ground clearance and parking at curbs.
•Winter weather driving capability.
•Wet weather driving capability.
•All-wheel driving capability.
When driving with the full-size dissimilarspare wheel and tire assembly additionalcaution should be given to:
•Towing a trailer.
•Driving vehicles equipped with acamper body.
•Driving vehicles with a load on thecargo rack.
Drive cautiously when using a full-sizedissimilar spare wheel and tire assemblyand seek service as soon as possible.
Tire Change Procedure
WARNINGS
When one of the front wheels is offthe ground, the transmission alonewill not prevent the vehicle frommoving or slipping off the jack, even if thetransmission is in park (P).
To help prevent your vehicle frommoving when changing a wheel, shiftthe transmission into park (P), setthe parking brake and use an appropriateblock or wheel chock to secure the wheeldiagonally opposite to the wheel beingchanged. For example, when changing thefront left wheel, place an appropriate blockor wheel chock on the right rear wheel.
Do not work on your vehicle whenthe jack is the only support. If thevehicle slips off the jack, you orsomeone else could be seriously injured.

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.
Ib-ft (Nm)*Bolt size
100 (135)1/2-20 x 1.5
*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).
Wheel pilot boreA
Inspect the wheel pilot bore andmounting surface prior to installation.Remove any visible corrosion or looseparticles.
