Under certain conditions, the enginecooling fan may continue to run for severalminutes after you switch your vehicle off.
ENGINE COOLANT CHECK
WARNINGS
Never remove the coolant reservoircap when the engine is running orhot.
Do not put coolant in the windshieldwasher reservoir. If sprayed on thewindshield, coolant could make itdifficult to see through the windshield.
To reduce the risk of personal injury,make sure the engine is cool beforeunscrewing the coolant pressurerelief cap. The cooling system is underpressure. Steam and hot liquid can comeout forcefully when you loosen the capslightly.
Do not add coolant further than theMAX mark.
When the engine is cold, check theconcentration and level of the coolant atthe intervals listed in the scheduledmaintenance information. See ScheduledMaintenance (page 409).
Note:Make sure that the coolant level isbetween the MIN and MAX marks on thecoolant reservoir.
Note: Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.
Maintain coolant concentration within48% to 50%, which equates to a freezepoint between -29°F (-34°C) and -35°F(-37°C). Coolant concentration should bechecked using a refractometer. We do notrecommend the use of hydrometers orcoolant test strips for measuring coolantconcentration.
Adding Coolant
WARNINGS
Do not add engine coolant when theengine is hot. Failure to follow thisinstruction could result in personalinjury.
Never remove the coolant reservoircap when the engine is running orhot.
Note: Automotive fluids are notinterchangeable. Take care not to putengine coolant in the windshield washerfluid reservoir or windshield washer fluid inthe engine coolant reservoir.
Note: Do not use stop leak pellets, coolingsystem sealants, or non-specified additivesas they can cause damage to the enginecooling or heating systems. Resultingcomponent damage may not be covered bythe vehicle Warranty.
It is very important to use predilutedcoolant approved to the correctspecification in order to avoid plugging thesmall passageways in the engine coolingsystem. See Capacities andSpecifications (page 268). Do not mixdifferent colors or types of coolant in yourvehicle. Mixing of engine coolants or usingan incorrect coolant may harm the engineor cooling system components and maynot be covered by the vehicle Warranty.
Note:If prediluted coolant is not available,use the approved concentrated coolantdiluting it to 50/50 with distilled water. SeeCapacities and Specifications (page 268).Using water that has not been deionisedmay contribute to deposit formation,corrosion and plugging of the small coolingsystem passageways.

Note:Changes or modifications notexpressively approved by the partyresponsible for compliance could void theuser's authority to operate the equipment.The term "IC:" before the radio certificationnumber only signifies that Industry Canadatechnical specifications were met.
Changing Tires With a TirePressure Monitoring System
Note:Each road tire is equipped with a tirepressure sensor located inside the wheeland tire assembly cavity. The pressuresensor is attached to the valve stem. Thepressure sensor is covered by the tire and isnot visible unless the tire is removed. Takecare when changing the tire to avoiddamaging the sensor.
You should always have your tires servicedby an authorized dealer.
Check the tire pressure periodically (atleast monthly) using an accurate tiregauge. See Inflating Your Tires in thischapter.
Understanding Your Tire PressureMonitoring System
The tire pressure monitoring systemmeasures pressure in your four road tiresand sends the tire pressure readings toyour vehicle. The low tire pressure warninglight will turn on if the tire pressure issignificantly low. Once the light isilluminated, your tires are under-inflatedand need to be inflated to themanufacturer’s recommended tirepressure. Even if the light turns on and ashort time later turns off, your tire pressurestill needs to be checked.
When Your Temporary Spare Tire isInstalled
When one of your road tires needs to bereplaced with the temporary spare, thesystem will continue to identify an issue toremind you that the damaged road wheeland tire assembly needs to be repaired andput back on your vehicle.
To restore the full function of the tirepressure monitoring system, have thedamaged road wheel and tire assemblyrepaired and remounted on your vehicle.
When You Believe Your System is NotOperating Properly
The main function of the tire pressuremonitoring system is to warn you whenyour tires need air. It can also warn you inthe event the system is no longer capableof functioning as intended. See thefollowing chart for information concerningyour tire pressure monitoring system:

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
