Make sure tires are at the proper pres-sure. See Inflating your tires in thischapter. After inflating your tires to themanufacturer’s recommended pressureas shown on the Tire Label (located onthe edge of driver’s door or the B-Pillar),the vehicle must be driven for at leasttwo minutes over 20 mph (32 km/h)before the light turns off.

When Inflating Your Tires
WARNING: Do not use the tirepressure displayed in the informationdisplay as a tire pressure gauge. Failureto follow this instruction could result inpersonal injury or death.
When putting air into your tires (such as ata gas station or in your garage), the tirepressure monitoring system will notrespond immediately to the air added toyour tires.
It could take up to two minutes of drivingover 20 mph (32 km/h) for the light to turnoff after you have filled your tires to therecommended inflation pressure.

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 pressurecould 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 pressurecould decrease about 3 psi (21 kPa) for adrop of 30°F (17°C) in ambienttemperature. This lower pressure valuecould be detected by the tire pressuremonitoring system as being significantlylower than the recommended inflationpressure 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 oneor more tires are flat, repair as necessary.Check the air pressure in the road tires. Ifany tire is under-inflated, carefully drivethe vehicle to the nearest location whereair can be added to the tires. Inflate all thetires to the recommended inflationpressure.
CHANGING A ROAD WHEEL (IF
EQUIPPED)
WARNING: If the tire pressuremonitor sensor becomes damaged itmay not function.
Note:You should only use tire sealants inroadside emergencies as they may causedamage to the tire pressure monitoringsystem sensor.
Note:The tire pressure monitoring systemindicator light illuminates 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 when 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 326). 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 theseguidelines could result in an increasedrisk of loss of vehicle control, injury ordeath.
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:

3.Full-size dissimilar spare withoutlabel on wheel
When driving with the full-size dissimilarspare wheel and tire assembly, do not:
•Exceed 75 mph (120 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:
•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.

WARNING: When you install a wheel, always remove any corrosion, dirt or foreignmaterials present on the mounting surfaces of the wheel or the surface of the wheelhub, brake drum or brake disc that contacts the wheel. Make sure to secure any fastenersthat attach the rotor to the hub so they do not interfere with the mounting surfaces ofthe wheel. Installing wheels without correct metal-to-metal contact at the wheelmounting surfaces can cause the wheel nuts to loosen and the wheel to come off whileyour vehicle is in motion, resulting in loss of vehicle control, personal injury or death.
