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 this 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 thesystem sensors See Tire PressureMonitoring System (page 260). Replacethe spare tire with a road tire as soon aspossible. During repairing or replacing ofthe flat tire, have the authorized dealerinspect the system sensor for damage.
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

WARNING
To reduce the risk of potential tirefailure that could lead to seriousinjury or death, increase the front andrear tire placard pressures by the amountshown on the warning label, located oneither the driver side B-pillar or door, whendriving over 100 mph (160 km/h). Onlytravel at speeds over 100 mph (160 km/h)where it is legal and conditions allow. Thetire placard pressure can be found on thetire placard located on either the driver sideB-pillar or door of your vehicle.
Warning: Failure to follow theseinstructions can result in a lossof vehicle stability due to tirefailure that could lead to serious injury ordeath. If you are not sure about the propertire inflation pressures, contact anauthorized dealer or service center.
Your tires may require additional inflationpressure for operation at speeds greaterthan 100 mph (160 km/h). If this label ispresent on your vehicle, you must adjustthe tire pressure accordingly.
