If you drive in extremely hot climates, youmay need to decrease the coolantconcentration to 40%.
Note:A coolant concentration of 40%provides improved overheat protection.Coolant concentrations below 40%decrease the overheat and corrosionprotection characteristics of the coolant andcould cause engine damage.
Coolant Change
WARNING: Do not dispose ofcoolant in the household refuse or thepublic sewage system. Use an authorizedwaste disposal facility.
Change the coolant at specific mileageintervals. Refer to the scheduledmaintenance information. See NormalScheduled Maintenance (page 542).
Note:Dispose of used coolant in theappropriate manner.
Follow your community's regulations andstandards for recycling and disposing ofautomotive fluids.
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
WARNING: If you continue to driveyour vehicle when the engine isoverheating, the engine could stopwithout warning. Failure to follow thisinstruction could result in the loss ofcontrol of your vehicle.
If the engine begins to overheat,the coolant temperature gaugemoves toward the 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
WARNING: Fail-safe mode is foruse during emergencies only. Operateyour vehicle in fail-safe mode only aslong as necessary to bring your vehicleto rest in a safe location and seekimmediate repairs. When in fail-safemode, your vehicle will have limitedpower, will not be able to maintainhigh-speed operation, and maycompletely shut down without warning,potentially losing engine power, powersteering assist, and power brake assist,which may increase the possibility of acrash resulting in serious injury.

1.Stop your vehicle as soon as it is safeto do so. Fully apply the parking brake,shift into park (P) or neutral (N).
2.Leave the engine running until thecoolant temperature gauge needlereturns to the normal position. If thetemperature does not drop afterseveral minutes, follow the remainingsteps.
3.Switch the engine off and wait for it tocool. Check the coolant level.
4.If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
5.If the coolant level is normal, restartthe engine and continue.
ENGINE AIR FILTER
CHANGING THE ENGINE AIRFILTER
WARNING: To reduce the risk ofvehicle damage and personal burninjuries, do not start your engine with theair cleaner removed and do not removeit while the engine is running.
Change the engine air filter element at theproper intervals. See Normal ScheduledMaintenance (page 542).
When changing the engine air filter, useonly the air filter element listed. SeeMotorcraft Parts (page 464).
Note: Failure to use the correct air filterelement may result in severe enginedamage. Resulting component damagemay not be covered by the vehicle Warranty.
Note: When servicing the air cleaner, donot allow foreign material to enter the airinduction system.
1.Release the two clamps that securethe cover to the air filter housing. Pushthe air filter cover toward the front ofthe vehicle and up slightly to release it.
2.Remove the air filter element from theair filter housing.
3.Install the new air filter element.
4.Replace the air filter housing cover andsecure all the clamps. Be careful notto crimp the filter element edgesbetween the air filter housing andcover, and make sure that you properlyalign the tabs on the edge into theslots.
CHANGING THE FUEL FILTER
Your vehicle has a lifetime fuel filter thatintegrates with the fuel tank. It does notneed regular maintenance or replacement.

If you replace the battery make sure itmatches the electrical requirements ofyour vehicle.
If you disconnect or replace the batteryand your vehicle has an automatictransmission, it must relearn its adaptivestrategy. Because of this, the transmissionmay shift firmly when first driven. This isnormal operation while the transmissionfully updates its operation to optimumshift feel.
Battery Sensor Reset
When you install a new battery, reset thebattery sensor by doing the following:
1.Switch the ignition on, and leave theengine off.
Note:Complete Steps 2 and 3 within 10seconds.
2.Flash the high beam headlamps fivetimes, ending with the high beams off.
3.Press and release the brake pedal threetimes.
The battery warning lamp flashes threetimes to confirm that the reset issuccessful.
Battery Management System (If
Equipped)
The system monitors battery conditionsand takes actions to extend battery life. Ifexcessive battery drain is detected, thesystem temporarily disables someelectrical systems to protect the battery.
Systems included are:
•Heated rear window.
•Heated seats.
•Climate control.
•Heated steering wheel.
•Audio unit.
•Navigation system.
A message may appear in the informationdisplay to alert you that battery protectionactions are active. This message is only fornotification that an action is taking place,and not intended to indicate an electricalproblem or that the battery requiresreplacement.
After battery replacement, or in somecases after charging the battery with anexternal charger, the battery managementsystem requires eight hours of vehicle sleeptime to relearn the battery state of charge.During this time, your vehicle must remainfully locked with the ignition switched off.
Note:Prior to relearning the battery stateof charge, the battery management systemmay temporarily disable some electricalsystems.
Electrical Accessory Installation
To make sure the battery managementsystem works correctly, do not connect anelectrical device ground connectiondirectly to the battery negative post. Thiscan cause inaccurate measurements ofthe battery condition and potentialincorrect system operation.
Note:If you add electrical accessories orcomponents to the vehicle, it may adverselyaffect battery performance and durability.This may also affect the performance ofother electrical systems in the vehicle.
Remove and Reinstall the Battery
Install a battery approved for use by ourspecifications. See Capacities andSpecifications (page 463).
To disconnect or remove the battery, dothe following:
1.Apply the parking brake and switch theignition off.
2.Switch all electrical equipment off, forexample lights and radio.
