Vehicle Settings and Personalization
See General Information (page 91).
Fuel Gauge
Note:The fuel gauge may vary slightlywhen your vehicle is moving or on a gradient.
Switch the ignition on. The fuel gaugeindicates approximately how much fuelremains in the fuel tank. The arrowadjacent to the fuel pump symbolindicates on which side of your vehicle thefuel filler door is located.
The needle should move toward F whenyou refuel your vehicle. If the needle pointsto E after adding fuel, this indicates yourvehicle needs service soon.
After refueling, the needle may not alwaysreturn to the exact same position. This isnormal.
Note:It may take a short time for theneedle to reach F after leaving the gasstation. This is normal and depends uponthe slope of pavement at the gas station.
Note:The fuel amount dispensed into thetank is a little less or more than the gaugeindicated. This is normal and depends uponthe slope of pavement at the gas station.
Note:If the gas station nozzle shuts offbefore the tank is full, try a different gaspump nozzle.
Note:There is a small reserve left in thetank when the fuel gauge reaches empty.
Low Fuel Reminder
A low reminder displays when the distanceto empty reaches 50 miles (80 km) toempty.
Note:The low fuel reminder can appear atdifferent fuel gauge positions depending onfuel economy conditions. This variation isnormal.
Engine Coolant Temperature Gauge
Shows the temperature of the enginecoolant. At normal operating temperature,the needle remains in the center section.If the needle enters the red section, theengine is overheating. Stop the engine,switch the ignition off and determine thecause once the engine has cooled down.
Note:Do not restart the engine until youconclude the cause of overheating.
WARNING
Never remove the coolant reservoircap while the engine is running or hot.The hot coolant is under pressureand may cause serious burns.

Transmission

The transfer case supples power to all fourwheels. On four-wheel drive vehicles, thetransfer case allows you to select different4WD modes when necessary. You can findinformation on transfer case operation andshifting procedures in this chapter. You canfind information on transfer casemaintenance in the Maintenance chapter.You should become thoroughly familiarwith this information before you operateyour vehicle.
Four-wheel drive (when you select a 4WDmode) uses all four wheels to power yourvehicle. This increases traction, enablingyou to drive over terrain and roadconditions that a conventional two-wheeldrive vehicle cannot.
Basic Operating Principles
•Do not use 4H or 4L on dry, hardsurfaced roads. Doing so will produceexcessive noise, increase tire wear andmay damage drive components. 4H or4L modes are only intended forconsistently slippery or loose surfaces.
•Drive slower in strong crosswinds whichcan affect the normal steeringcharacteristics of your vehicle.
•When driving your vehicle on surfacesmade slippery by loose sand, water,gravel, snow or ice proceed with care.
If Your Vehicle leaves the Road
If your vehicle leaves the road, reduce yourvehicle speed and avoid severe braking.When your vehicle speed decreases, easeyour vehicle back onto the road. Do notturn the steering wheel sharply whilereturning your vehicle to the road.
It may be safer to stay on the shoulder ofthe road and slow down gradually beforereturning to the road. You may lose controlif you do not slow down or if you turn thesteering wheel too sharply or abruptly.
It may be less risky to strike small objects,such as freeway reflectors, with minordamage to your vehicle rather thanattempt a sudden return to the road whichcould cause your vehicle to slide sidewaysout of control or roll over. Remember, yoursafety and the safety of others should beyour primary concern.
If your vehicle gets stuck
WARNING
Do not spin the wheels at over 35mph (56 km/h). The tires may failand injure a passenger or bystander.
Note:Do not rock your vehicle if the engineis not at normal operating temperature,damage to the transmission may occur.
Note:Do not rock your vehicle for morethan a minute, damage to the transmissionand tires may occur or the engine mayoverheat.
If your vehicle gets stuck in mud or snow itmay be rocked out by shifting betweenforward and reverse gears, stoppingbetween shifts, in a steady pattern. Presslightly on the accelerator in each gear.
Emergency Maneuvers
In an unavoidable emergency situationwhere a sudden sharp turn must be made,remember to avoid over-driving yourvehicle (i.e. turn the steering wheel only asrapidly and as far as required to avoid theemergency). Excessive steering can resultin loss of vehicle control. Apply smoothpressure to the accelerator pedal or brakepedal when changes in vehicle speed arerequired. Avoid abrupt steering,acceleration and braking. This could resultin an increased risk of vehicle roll over, lossof vehicle control and personal injury. Useall available road surface to bring yourvehicle to a safe direction of travel.

Four-Wheel Drive (If Equipped)

Note:Avoid turning on steep slopes or hills.A danger lies in losing traction, slippingsideways and possible vehicle roll over.Whenever driving on a hill, determinebeforehand the route you will use. Do notdrive over the crest of a hill without seeingwhat conditions are on the other side. Donot drive in reverse over a hill without theaid of an observer.
Although natural obstacles may make itnecessary to travel diagonally up or downa hill or steep incline, you should alwaystry to drive straight up or straight down.
When climbing a steep slope or hill, startin a lower gear rather than downshifting toa lower gear from a higher gear once theascent has started. This reduces strain onthe engine and the possibility of stalling.
If your vehicle stalls, do not try to turnaround because this could cause vehicleroll over. It is better to reverse back to asafe location.
Apply just enough power to the wheels toclimb the hill. Too much power will causethe tires to slip, spin or lose traction,resulting in loss of vehicle control.
Descend a hill in the same gear you woulduse to climb up the hill to avoid excessivebrake application and brake overheating.Do not descend in neutral. Disengageoverdrive or move the transmissionselector lever to a lower gear. Whendescending a steep hill, avoid sudden hardbraking as you could lose control. The frontwheels have to be turning in order to steeryour vehicle.
If your vehicle has anti-lock brakes, applythe brakes steadily. Do not pump thebrakes.
Driving on Snow and Ice
WARNING
If you are driving in slipperyconditions that require tire chains orcables, then it is critical that you drivecautiously. Keep speeds down, allow forlonger stopping distances and avoidaggressive steering to reduce the chancesof a loss of vehicle control which can leadto serious injury or death. If the rear end ofyour vehicle slides while cornering, steer inthe direction of the slide until you regaincontrol of your vehicle.
Four-wheel drive vehicles have advantagesover two-wheel drive vehicles in snow andice but can skid like any other vehicle.Should you start to slide while driving onsnowy or icy roads, turn the steering wheelin the direction of the slide until you regaincontrol.
Avoid sudden applications of power andquick changes of direction on snow andice. Apply the accelerator slowly andsteadily when starting from a full stop.

•Your vehicle's brake system and thetrailer brake system workindependently of each other. Changingthe gain setting on the controller doesnot affect the operation of yourvehicle's brakes whether you attach atrailer or not.
•When you switch the engine off, thecontroller output is disabled and thedisplay and module shut down. Thecontroller module and display turn onwhen you switch the ignition on.
•The trailer brake controller is only afactory-installed or dealer-installeditem. Ford is not responsible forwarranty or performance of thecontroller due to misuse or customerinstallation.
Trailer Lamps
WARNING
Never connect any trailer lamp wiringto the vehicle's tail lamp wiring; thismay damage the electrical systemresulting in fire. Contact your authorizeddealer as soon as possible for assistancein proper trailer tow wiring installation.Additional electrical equipment may berequired.
Trailer lamps are required on most towedvehicles. Make sure all running lights, brakelights, turn signals and hazard lights areworking.
Before Towing a Trailer
Practice turning, stopping and backing upto get the feel of your vehicle-trailercombination before starting on a trip.When turning, make wider turns so thetrailer wheels clear curbs and otherobstacles.
When Towing a Trailer
•Do not drive faster than 70 mph (113km/h) during the first 500 miles (800kilometers).
•Do not make full-throttle starts.
•Check your hitch, electrical connectionsand trailer wheel lug nuts thoroughlyafter you have traveled 50 miles (80kilometers).
•When stopped in congested or heavytraffic during hot weather, place thegearshift in position P to aid engine andtransmission cooling and to help A/Cperformance.
•Turn off the speed control with heavyloads or in hilly terrain. The speedcontrol may turn off automaticallywhen you are towing on long, steepgrades.
•Shift to a lower gear when driving downa long or steep hill. Do not apply thebrakes continuously, as they mayoverheat and become less effective.
•If your transmission is equipped with aGrade Assist or Tow/Haul feature, usethis feature when towing. This providesengine braking and helps eliminateexcessive transmission shifting foroptimum fuel economy andtransmission cooling.
•If your vehicle is equipped withAdvanceTrac with RSC, this systemmay turn on during typical corneringmaneuvers with a heavily loaded trailer.This is normal. Turning the corner at aslower speed while towing may reducethis tendency.
•If you are towing a trailer frequently inhot weather, hilly conditions, at thegross combined weight rating (or anycombination of these factors), considerrefilling your rear axle with syntheticgear lubricant (if the axle is not alreadyfilled with it). See Capacities andSpecifications (page 304).

Towing

BREAKING-IN
You need to break in new tires forapproximately 300 miles (480kilometers). During this time, your vehiclemay exhibit some unusual drivingcharacteristics.
Avoid driving too fast during the first 1000miles (1600 kilometers). Vary your speedfrequently and change up through thegears early. Do not labor the engine.
Do not tow during the first 1000 miles(1600 kilometers).
REDUCED ENGINE
PERFORMANCE
WARNING
Continued operation will increase theengine temperature and cause theengine to shut down completely.
If the engine coolant temperature gaugeneedle moves to the upper limit position,the engine is overheating. See Gauges(page 84).
You must only drive your vehicle for a shortdistance if the engine overheats. Thedistance you can travel depends onambient temperature, vehicle load andterrain. The engine will continue to operatewith limited power for a short time.
If the engine temperature continues to rise,the fuel supply to the engine will reduce.The air conditioning will switch off and theengine cooling fan will operate continually.
1.Reduce your speed gradually and stopyour vehicle as soon as it is safe to doso.
2. Switch the engine off immediately toprevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level. See EngineCoolant Check (page 247).
5. Have your vehicle checked by anauthorized dealer as soon as possible.
ECONOMICAL DRIVING
Fuel economy is affected by several thingssuch as how you drive, the conditions youdrive under and how you maintain yourvehicle.
There are some things to keep in mind thatmay improve your fuel economy:
•Accelerate and slow down in a smooth,moderate fashion.
•Drive at steady speeds.
•Anticipate stops; slowing down mayeliminate the need to stop.
•Combine errands and minimizestop-and-go driving (When runningerrands, go to the furthest destinationfirst and then work your way backhome).
•Close the windows for high-speeddriving.
•Drive at reasonable speeds.
•Keep the tires properly inflated and useonly the recommended size.
•Use the recommended engine oil.
•Perform all regularly scheduledmaintenance.
There are also some things you may wantto avoid doing because they reduce yourfuel economy:
•Avoid sudden or hard accelerations.
•Avoid revving the engine before turningoff the car.
•Avoid long idle periods.
•Do not warm up your vehicle on coldmornings.
•Reduce the use of air conditioning andheat.

Driving Hints

Note:Coolants marketed for all makes andmodels may not be approved to Fordspecifications and may cause damage tothe cooling system. Resulting componentdamage may not be covered by the vehicleWarranty.
If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
To top up the coolant level do thefollowing:
1. Unscrew the cap slowly. Any pressureescapes as you unscrew the cap.
2. Add prediluted coolant approved tothe correct specification. SeeCapacities and Specifications (page304).
3. Add enough prediluted coolant toreach the correct level.
4.Replace the coolant reservoir cap, turnit clockwise until you feel a strongresistance.
5. Check the coolant level in the coolantreservoir the next few times you driveyour vehicle. If necessary, add enoughprediluted engine coolant to bring thecoolant level to the correct level.
If you have to add more than 1.1 qt (1 L) ofengine coolant per month, have yourvehicle checked as soon as possible.Operating an engine with a low level ofcoolant can result in engine overheatingand possible engine damage.
Note:During normal vehicle operation, thecoolant may change color from orange topink or light red. As long as the coolant isclear and uncontaminated, this color changedoes not indicate the coolant has degradednor does it require the coolant to be drained,the system to be flushed, or the coolant tobe replaced.
Note:In case of emergency, you can add alarge amount of water without coolant inorder to reach a vehicle service location.Water alone, without coolant, can causeengine damage from corrosion, overheatingor freezing. When you reach a servicelocation, you must have the cooling systemdrained and refilled with prediluted coolantapproved to the correct specification. SeeCapacities and Specifications (page 304).
Do not use the following as a coolantsubstitute:
•Alcohol.
•Methanol.
•Brine.
•Any coolant mixed with alcohol ormethanol antifreeze.
Alcohol and other liquids can cause enginedamage from overheating or freezing.
Do not add extra inhibitors or additives tothe coolant. These can be harmful andcompromise the corrosion protection ofthe coolant.
Recycled Coolant
We do not recommend the use of recycledcoolant as an approved recycling processis not yet available.
Dispose of used engine coolant in anappropriate manner. Follow yourcommunity's regulations and standardsfor recycling and disposing of automotivefluids.

Maintenance

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:
•You can decrease the coolantconcentration to 40%.
•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.
Coolant Change
At specific mileage intervals, as listed inthe scheduled maintenance information,the coolant should be changed. Addprediluted coolant approved to the correctspecification. See Capacities andSpecifications (page 304).
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.
