When Inflating Your Tires
When putting air into your tires (such as at agas station or in your garage), the tirepressure monitoring system may not respondimmediately to the air added to your tires.
It may take up to two minutes of driving over20 mph (32 km/h) for the light to turn off afteryou have filled your tires to therecommended inflation pressure.
How Temperature Affects Your TirePressure
The tire pressure monitoring system monitorstire pressure in each pneumatic tire. Whiledriving in a normal manner, a typicalpassenger tire inflation pressure mayincrease about 2–4 psi (14–28 kPa) from acold start situation. If the vehicle is stationaryovernight with the outside temperaturesignificantly lower than the daytimetemperature, the tire pressure may decreaseabout 3 psi (21 kPa) for a drop of 30°F (17°C)in ambient temperature. This lower pressurevalue may be detected by the tire pressuremonitoring system as being significantlylower than the recommended inflation
pressure and activate the system warninglight for low tire pressure. If the low tirepressure warning light is on, visually checkeach tire to verify that no tire is flat. If one ormore tires are flat, repair as necessary.Check the air pressure in the road tires. Ifany tire is under-inflated, carefully drive thevehicle to the nearest location where air canbe added to the tires. Inflate all the tires tothe recommended inflation pressure.
CHANGING A ROAD WHEEL
WARNING: Do not use tire sealantsas they may damage the tire pressuremonitoring system.
WARNING: If the tire pressuremonitor sensor becomes damaged it maynot function.
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.
Note:If your vehicle is equipped with theoptional 5th road wheel and tire assembly,the storage location in the luggagecompartment is for temporary use only. Theoptional full size road wheel and tireassembly should be stored outside thevehicle after delivery.
If you get a flat tire while driving, do not applythe brake heavily. Instead, graduallydecrease your speed. Hold the steeringwheel firmly and slowly move to a safe placeon the side of the road.

Have a flat serviced by an authorized dealerin order to prevent damage to the tirepressure monitoring system sensors. SeeTire Pressure Monitoring System (page 329).Replace the spare tire with a road tire assoon as possible. During repairing orreplacing of the flat tire, have the authorizeddealer inspect the tire pressure monitoringsystem sensor for damage.
Dissimilar Spare Wheel and TireAssembly Information
WARNING: Failure to follow theseguidelines could result in an increased riskof loss of vehicle control, injury or death.
If you have a dissimilar spare wheel and tire,then it is intended for temporary use only.This means that if you need to use it, youshould replace it as soon as possible with aroad wheel and tire assembly that is thesame size and type as the road tires andwheels that were originally provided by Ford.If the dissimilar spare tire or wheel isdamaged, it should be replaced rather thanrepaired.
A dissimilar spare wheel and tire assemblyis defined as a spare wheel and tire assemblythat is different in brand, size or appearancefrom the road tires and wheels and can beone of three types:
1. T-type mini-spare: This spare tire beginswith the letter T for tire size and may haveTemporary Use Only molded in the sidewall.
2. Full-size dissimilar spare with label onwheel: This spare tire has a label on thewheel that states: THIS WHEEL AND TIREASSEMBLY FOR TEMPORARY USE ONLY.
When driving with one of the dissimilar sparetires 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 washing equipment.
•Try to repair the dissimilar spare tire.
Use of one of the dissimilar spare tires listedabove at any one wheel location 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.
3. Full-size dissimilar spare without labelon 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 washing equipment.
•Use snow chains on the end of thevehicle with the dissimilar spare wheeland tire assembly.

Tire Change Procedure
WARNING: When one of the frontwheels is off the ground, the transmissionalone will not prevent the vehicle frommoving or slipping off the jack, even if thetransmission is in park (P).
WARNING: To help prevent yourvehicle from moving when changing awheel, shift the transmission into park (P),set the parking brake and use anappropriate block or wheel chock tosecure the wheel diagonally opposite tothe wheel being changed. For example,when changing the front left wheel, placean appropriate block or wheel chock onthe right rear wheel.
WARNING: No person should placeany portion of their body under a vehiclethat is supported by a jack.
WARNING: Do not attempt to changea tire on the side of the vehicle close tomoving traffic. Pull far enough off the roadto avoid the danger of being hit whenoperating the jack or changing the wheel.
WARNING: Always use the jackprovided as original equipment with yourvehicle. If using a jack other than the oneprovided, make sure the jack capacity isadequate for the vehicle weight, includingany vehicle cargo or modifications. If youare unsure if the jack capacity is adequate,contact the authorized dealer.
Note:Passengers should not remain in yourvehicle when the vehicle is being jacked.
Note:Jack at the specified locations to avoiddamage to the vehicle.
Note:If your vehicle came equipped with anextra full size wheel and tire assembly(placed in the cargo area), be sure to storethe wheel and tire assembly outside of thevehicle after delivery (livery vehicles only).

Wheel Lug Nut Torque Specifications
WARNING: When you install a wheel, always remove any corrosion, dirt or foreign materials present on the mounting surfaces of thewheel or the surface of the wheel hub, brake drum or brake disc that contacts the wheel. Make sure to secure any fasteners that attachthe rotor to the hub so they do not interfere with the mounting surfaces of the wheel. Installing wheels without correct metal-to-metal contactat the wheel mounting surfaces can cause the wheel nuts to loosen and the wheel to come off while your vehicle is in motion, resulting inloss of vehicle control, personal injury or death.
