Severe Climates
If you drive in extremely cold climates:
•It may be necessary to increase thecoolant concentration above 50%.
•A coolant concentration of 60%provides improved freeze pointprotection. Coolant concentrationsabove 60% decrease the overheatprotection characteristics of thecoolant and may cause enginedamage.
If you drive in extremely hot climates:
•It may be necessary to decrease thecoolant concentration to 40%.
•A coolant concentration of 40%provides improved overheat protection.Coolant concentrations below 40%decrease the freeze and corrosionprotection characteristics of thecoolant and may cause enginedamage.
Vehicles driven year-round in non-extremeclimates should use prediluted coolant foroptimum cooling system and engineprotection.
Fail-Safe Cooling
Fail-safe cooling allows you to temporarilydrive your vehicle before any incrementalcomponent damage occurs. The fail-safedistance depends on ambienttemperature, vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, thecoolant temperature gauge moves towardthe red zone:
A warning lamp illuminates anda message may appear in theinformation display.
If the engine reaches a presetover-temperature condition, the engineautomatically switches to alternatingcylinder operation. Each disabled cylinderacts as an air pump and cools the engine.
When this occurs, your vehicle stilloperates, however:
•Engine power is limited.
•The air conditioning system turns off.
Continued operation increases the enginetemperature, causing the engine tocompletely shut down. Your steering andbraking effort increases in this situation.
When the engine temperature cools, youcan re-start the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.
When Fail-Safe Mode Is Activated
WARNINGS
Fail-safe mode is for use duringemergencies only. Operate yourvehicle in fail-safe mode only as longas necessary to bring your vehicle to restin a safe location and seek immediaterepairs. When in fail-safe mode, yourvehicle will have limited power, will not beable to maintain high-speed operation, andmay completely shut down withoutwarning, potentially losing engine power,power steering assist, and power brakeassist, which may increase the possibilityof a crash resulting in serious injury.
Never remove the coolant reservoircap while the engine is running or hot.
Your vehicle has limited engine powerwhen in the fail-safe mode, drive yourvehicle with caution. Your vehicle does notmaintain high-speed operation and theengine may operate poorly.
Remember that the engine is capable ofautomatically shutting down to preventengine damage. In this situation:

Maintenance

To avoid fluid contamination, the reservoircap must remain in place and fully tight,unless you are adding fluid.
Only use fluid that meets Fordspecifications. See Capacities andSpecifications (page 415).
POWER STEERING FLUID
CHECK
Check the power steering fluid. SeeScheduled Maintenance (page 573). Ifadding fluid is necessary, use onlyMERCON LV ATF
Note:This procedure is for vehicles withgasoline engines. Vehicles with dieselengines are similar. See Under HoodOverview in your diesel supplement.
Check the fluid level when it is at ambienttemperature.
1. Check the fluid level in the reservoir. Itshould be between the MIN and MAXrange. Do not add fluid if the level iswithin this range.
2.If the fluid level is low, add fluid to bringthe fluid level up to between the MINand MAX range.
3. Switch the engine on.
4.While the engine idles, turn the steeringwheel left and right several times.
5. Switch the engine off.
6. Recheck the fluid level in the reservoir.Do not add fluid if the level is betweenthe MIN and MAX range.
7. If the fluid is low, add fluid in smallamounts, continuously checking thelevel until it is between the MIN andMAX range. For proper fluid type, SeeCapacities and Specifications (page415). Be sure to put the cap back on thereservoir.
WASHER FLUID CHECK
WARNING
If you operate your vehicle intemperatures below 40°F (5°C), usewasher fluid with antifreezeprotection. Failure to use washer fluid withantifreeze protection in cold weather couldresult in impaired windshield vision andincrease the risk of injury or accident.
Add fluid to fill the reservoir if the level islow. Only use a washer fluid that meetsFord specifications. See Capacities andSpecifications (page 415).

Vehicle Care

•Higher - to allow higher load carryingcapacity and to allow it to travel overrough terrain without getting hung upor damaging underbody components.
•Shorter - to give it the capability toapproach inclines and drive over thecrest of a hill without getting hung upor damaging underbody components.All other things held equal, a shorterwheelbase may make your vehiclequicker to respond to steering inputsthan a vehicle with a longer wheelbase.
•Narrower - to provide greatermaneuverability in tight spaces,particularly in off-road use.
As a result of the above dimensionaldifferences, Sport utility vehicles andtrucks often will have a higher center ofgravity and a greater difference in centerof gravity between the loaded andunloaded condition. These differences thatmake your vehicle so versatile also makeit handle differently than an ordinarypassenger car.

Wheels and TiresE145299 E168583

Note:Do not reduce tire pressureto change the ride characteristicsof the vehicle. If you do notmaintain the inflation pressure atthe levels specified by Ford, yourvehicle may experience a conditionknown as shimmy. Shimmy is asevere vibration and oscillation inthe steering wheel after the vehicletravels over a bump or dip in theroad that does not dampen out byitself. Shimmy may result fromsignificant under-inflation of thetires, improper tires (load range,size, or type), or vehiclemodifications such as lift-kits. Inthe event that your vehicleexperiences shimmy, you shouldslowly reduce speed by either liftingoff the accelerator pedal or lightlyapplying the brakes. The shimmywill cease as the vehicle speeddecreases.
Maximum Inflation Pressure isthe tire manufacturer's maximumpermissible pressure and thepressure at which the maximumload can be carried by the tire. Thispressure is normally higher thanthe manufacturer’s recommendedcold inflation pressure which canbe found on the SafetyCompliance Certification Label(affixed to either the door hingepillar, door-latch post, or the dooredge that meets the door-latchpost, next to the driver's seatingposition), or Tire Label located on
the B-pillar or the edge of thedriver's door. The cold inflationpressure should never be set lowerthan the recommended pressureon the Safety ComplianceCertification Label or Tire Label.
When weather temperaturechanges occur, tire inflationpressures also change. A 10°F(6°C) temperature drop cancause a corresponding drop of 1psi (7 kPa) in inflation pressure.Check your tire pressuresfrequently and adjust them to theproper pressure which can befound on the Safety ComplianceCertification Label or Tire Label.
To check the pressure in yourtire(s):
1. Make sure the tires are cool,meaning they are not hot fromdriving even a mile.
Note:If you are checking tirepressure when the tire is hot, (forexample, driven more than 1 mile[1.6 kilometers]), never bleed orreduce air pressure. The tires arehot from driving and it is normal forpressures to increase aboverecommended cold pressures. Ahot tire at or below recommendedcold inflation pressure could besignificantly under-inflated.

USING SNOW CHAINS
WARNING
Snow tires must be the same size,load index, speed rating as thoseoriginally provided by Ford. Use ofany tire or wheel not recommended byFord can affect the safety andperformance of your vehicle, which couldresult in an increased risk of loss of vehiclecontrol, vehicle rollover, personal injury anddeath. Additionally, the use ofnon-recommended tires and wheels couldcause steering, suspension, axle, transfercase or power transfer unit failure.
Note:Do not use snow chains on vehicleswith 20 inch wheels and tires.
The tires on your vehicle have all-weathertreads to provide traction in rain and snow.However, in some climates, you may needto use snow tires and cables. If you needto use cables, it is recommended that steelwheels (of the same size andspecifications) be used, as cables may chipaluminum wheels.
Note:The suspension insulation andbumpers will help prevent vehicle damage.Do not remove these components from yourvehicle when using snow tires and chains.
Follow these guidelines when using snowtires and chains:
•If possible, avoid fully loading yourvehicle
•Use only SAE Class S chains.
•Install chains securely, verifying thatthe chains do not touch any wiring,brake lines or fuel lines.
•Drive cautiously. If you hear the chainsrub or bang against your vehicle, stopand retighten the chains. If this doesnot work, remove the chains to preventdamage to your vehicle.
•Remove the tire chains when they areno longer needed. Do not use tirechains on dry roads.
If you have any questions regarding snowchains or cables, please contact yourauthorized dealer.
TIRE PRESSURE MONITORING
SYSTEM
Vehicle Tire Pressure MonitoringSystem
WARNING
The tire pressure monitoring systemis not a substitute for manuallychecking tire pressures. You shouldperiodically check tire pressures using apressure gauge. Failure to correctlymaintain tire pressures could increase therisk of tire failure, loss of control, vehiclerollover and personal injury.
Each tire, including the spare (ifprovided), should be checkedmonthly when cold and inflatedto the inflation pressure recommended bythe vehicle manufacturer on the vehicleplacard or tire inflation pressure label. (Ifyour vehicle has tires of a different sizethan the size indicated on the vehicleplacard or tire inflation pressure label, youshould determine the proper tire inflationpressure for those tires.)

The trailer tire pressure monitoring systemcan be reset through the menu in theinformation display. See GeneralInformation (page 111). Performing thetrailer setup process also resets the trailertire pressure monitoring system.
CHANGING A ROAD WHEEL
WARNINGS
The use of tire sealant may damageyour tire pressure monitoring systemand should only be used in roadsideemergencies. If you must use a sealant, theFord Tire Mobility Kit sealant should beused. The tire pressure monitoring systemsensor and valve stem on the wheel mustbe replaced by an authorized dealer afteruse of the sealant.
If the tire pressure monitor sensorbecomes damaged, it will no longerfunction. See Tire PressureMonitoring System (page 394).
Note:If your vehicle is equipped with thetire pressure monitoring system, theindicator 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.
If your vehicle is equipped with the tirepressure monitoring system, have a flatserviced by an authorized dealer in orderto prevent damage to the system sensors.See Tire Pressure Monitoring System(page 394). Replace the spare tire with aroad tire as soon as possible. Duringrepairing or replacing of the flat tire, havethe authorized dealer inspect the systemsensor 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
