Note:Do not remove the dipstick when theengine is running.
Note: If the oil level is between themaximum and minimum marks, the oil levelis acceptable. Do not add oil.
Note:The oil consumption of new enginesreaches its normal level after approximately3,000 mi (5,000 km).
Adding Engine Oil
WARNING: Do not remove the fillercap when the engine is running.
Do not use supplemental engine oil additivesbecause they are unnecessary and couldlead to engine damage that may not becovered by the vehicle Warranty.
Only use oils certified for gasoline enginesby the American Petroleum Institute (API). An oil with this trademark symbol conformsto the current engine and emission systemprotection standards and fuel economyrequirements of the International LubricantsSpecification Advisory Committee (ILSAC).
To top up the engine oil level do thefollowing:
1. Clean the area surrounding the engineoil filler cap before you remove it.
2. Remove the engine oil filler cap. SeeUnder Hood Overview (page 362). Turnit counterclockwise and remove it.
3. Add engine oil that meets ourspecifications. See Capacities andSpecifications (page 426). You may haveto use a funnel to pour the engine oil intothe opening.
4. Recheck the oil level.
5. If the oil level is correct, replace thedipstick and make sure it is fully seated.
6. Replace the engine oil filler cap. Turn itclockwise until you feel a strongresistance.
Note: Do not add oil further than themaximum mark. Oil levels above themaximum mark may cause engine damage.
Note:Make sure you install the oil filler capcorrectly.
Note:Soak up any spillage with anabsorbent cloth immediately.

If you drive in extremely hot climates:
•You can decrease the coolantconcentration to 40%.
•Coolant concentrations below 40%decrease the freeze and corrosionprotection characteristics of the coolantand may cause engine damage.
Vehicles driven year-round in non-extremeclimates should use prediluted coolant foroptimum cooling system and engineprotection.
Coolant Change
At specific mileage intervals, as listed in thescheduled maintenance information, thecoolant should be changed. Add predilutedcoolant approved to the correct specification.See Capacities and Specifications (page422).
Fail-Safe Cooling
Fail-safe cooling allows you to temporarilydrive your vehicle before any incrementalcomponent damage occurs. The fail-safedistance depends on ambient temperature,vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat,the coolant temperature gaugemoves toward the red zone:
A warning lamp illuminates and amessage may appear in theinformation display.
If the engine reaches a presetover-temperature condition, the engineautomatically switches to alternating cylinderoperation. Each disabled cylinder acts as anair pump and cools the engine.
When this occurs, your vehicle still operates,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, you canre-start the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.
When Fail-Safe Mode Is Activated
WARNING: Fail-safe mode is for useduring emergencies only. Operate yourvehicle in fail-safe mode only as long asnecessary to bring your vehicle to rest ina safe location and seek immediate repairs.When in fail-safe mode, your vehicle willhave limited power, will not be able tomaintain high-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.
WARNING: Do not remove thecoolant reservoir cap when the coolingsystem is hot. Wait 10 minutes for thecooling system to cool down. Cover thecoolant reservoir cap with a thick cloth toprevent the possibility of scalding andslowly remove the cap. Failure to followthis instruction could result in personalinjury.

Maintenance

Note:For flexible fuel vehicles, if you areoperating on E85, you may experience poorstarts or an inability to start the engine anddriveability problems until the fuel trim andethanol content have been relearned.
Make sure that you dispose of old batteriesin an environmentally friendly way. Seekadvice from your local authority aboutrecycling old batteries.
If storing your vehicle for more than 30 dayswithout recharging the battery, werecommend that you disconnect the negativebattery cable to maintain battery charge forquick starting.
Battery Management System (If Equipped)
The battery management system monitorsbattery conditions and takes actions toextend battery life. If excessive battery drainis detected, the system temporarily disablessome electrical systems to protect thebattery.
Systems included are:
•Heated rear window.
•Heated seats.
•Climate control.
•Heated steering wheel.
•Audio unit.
•Navigation system.
A message may appear in the informationdisplays to alert you that battery protectionactions are active. These messages are onlyfor notification that an action is taking place,and not intended to indicate an electricalproblem or that the battery requiresreplacement.
After battery replacement, or in some casesafter charging the battery with an externalcharger, the battery management systemrequires eight hours of vehicle sleep time torelearn the battery state of charge. Duringthis time your vehicle must remain fullylocked with the ignition switched off.
Note:Prior to relearning the battery state ofcharge, 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 connection directlyto the battery negative post. This can causeinaccurate measurements of the batterycondition and potential incorrect systemoperation.
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.

CLEANING THE INSTRUMENT
PANEL AND INSTRUMENT
CLUSTER LENS
WARNING: Do not use chemicalsolvents or strong detergents whencleaning the steering wheel or instrumentpanel to avoid contamination of the airbagsystem.
Note:Follow the same procedure ascleaning leather seats for cleaning leatherinstrument panels and leather interior trimsurfaces. See Cleaning Leather Seats (page388).
Clean the instrument panel and cluster lenswith a clean, damp and soft cloth, then usea clean, dry and soft cloth to dry these areas.
•Avoid cleaners or polishes that increasethe gloss of the upper portion of theinstrument panel. The dull finish in thisarea helps protect you from undesirablewindshield reflection.
•Do not use any household cleaningproducts or glass cleaners as these maydamage the finish of the instrumentpanel, interior trim and cluster lens.
•Wash or wipe your hands clean if youhave been in contact with certainproducts such as insect repellent andsuntan lotion to avoid possible damageto the interior painted surfaces.
•Do not allow air fresheners and handsanitizers to spill onto interior surfaces.If a spill occurs, wipe off immediately.Your warranty may not cover thesedamages.
If a staining liquid like coffee or juice hasbeen spilled on the instrument panel or oninterior trim surfaces:
1.Wipe up spilled liquid using a clean, softcloth as quickly as possible.
2. Use Motorcraft Premium Leather andVinyl Cleaner or a commercially availableleather cleaning product for automotiveinteriors. Test any cleaner or stainremover on an inconspicuous area.
3. Alternatively, wipe the surface with aclean, soft cloth and a mild soap andwater solution. Dry the area with a clean,soft cloth.
4.If necessary, apply more soap and watersolution or cleaning product to a clean,soft cloth and press it onto the soiledarea. Allow this to set at roomtemperature for 30 minutes.
5. Remove the soaked cloth, then with aclean, damp cloth, use a rubbing motionfor 60 seconds on the soiled area.

Vehicle Care

GENERAL INFORMATION
Use only approved wheel and tire sizes,using other sizes could damage your vehicle.If you change the diameter of the tires fromthat fitted at the factory, the speedometermay not display the correct speed. If youintend to change the size of the wheels fromthat fitted by the manufacturer, you cancheck the suitability with an authorizeddealer.
Additional information related to thefunctionality and maintenance of your tirescan be found later in this chapter. See TireCare (page 394).
You can find the recommended tire inflationpressures can on the Tire Label, which is onthe B-pillar or the edge of the driver door.You can also find this information on theSafety Compliance Certification Label, affixedto either the door hinge pillar, door-latchpost, or the door edge that meets the doorlatch post; next to the driver seating position.
We strongly recommend maintaining thesetire pressures at all times. Failure to followthe tire pressure recommendations cancause uneven treadwear patterns, reducedfuel economy, and adversely affect the wayyour vehicle handles.
Note:Check and set the tire pressure at theambient temperature in which you areintending to drive your vehicle and when thetires are cold.
Note:Check your tire pressures at least onceper month.
If your vehicle has a spare tire, set thepressure to the highest value given for yourvehicle and tire size combination.
Notice to utility vehicle and truckowners
WARNING: Utility vehicles have asignificantly higher rollover rate than othertypes of vehicles.
WARNING: Vehicles with a highercenter of gravity (utility and four-wheeldrive vehicles) handle differently thanvehicles with a lower center of gravity(passenger cars). Avoid sharp turns,excessive speed and abrupt steering inthese vehicles. Failure to drive cautiouslyincreases the risk of losing control of yourvehicle, vehicle rollover, personal injuryand death.
WARNING: In a rollover crash, anunbelted person is significantly more likelyto die than a person wearing a seatbelt.
WARNING: Do not becomeoverconfident in the ability of four-wheeldrive vehicles. Although a four-wheel drivevehicle may accelerate better than atwo-wheel drive vehicle in low tractionsituations, it won't stop any faster thantwo-wheel drive vehicles. Always drive ata safe speed.

•Higher - to allow higher load carryingcapacity and to allow it to travel overrough terrain without getting hung up ordamaging underbody components.
•Shorter - to give it the capability toapproach inclines and drive over thecrest of a hill without getting hung up ordamaging underbody components. Allother 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 and trucksoften have a higher center of gravity and agreater difference in center of gravitybetween the loaded and unloaded condition.These differences that make your vehicle soversatile also make it handle differently thanan ordinary passenger car.
