How Your Vehicle Differs FromOther Vehicles
WARNING
Vehicles with a higher center ofgravity such as utility and four-wheeldrive vehicles handle differently thanvehicles with a lower center of gravity.Utility and four-wheel drive vehicles arenot designed for cornering at speeds ashigh as passenger cars any more thanlow-slung sports cars are designed toperform satisfactorily under off-roadconditions. Avoid sharp turns, excessivespeed and abrupt maneuvers in thesevehicles. Failure to drive cautiously couldresult in an increased risk of loss of vehiclecontrol, vehicle rollover, personal injury anddeath.
Truck and utility vehicles can differ fromsome other vehicles. Your vehicle may behigher to allow it to travel over roughterrain without getting hung up ordamaging underbody components.
The differences that make your vehicle soversatile also make it handle differentlythan an ordinary passenger car.
Maintain steering wheel control at alltimes, especially in rough terrain. Sincesudden changes in terrain can result inabrupt steering wheel motion, make sureyou grip the steering wheel from theoutside. Do not grip the spokes.
Drive cautiously to avoid vehicle damagefrom concealed objects such as rocks andstumps.
You should either know the terrain orexamine maps of the area before driving.Map out your route before driving in thearea. To maintain steering and brakingcontrol of your vehicle, you must have allfour wheels on the ground and they mustbe rolling, not sliding or spinning.
Driving Off-Road With Truck andUtility Vehicles
Note:On some models, the initial shift fromtwo-wheel drive to four-wheel drive whilethe vehicle is moving can cause somemomentary clunk and ratcheting sounds.This is the front drivetrain coming up tospeed and the automatic locking hubsengaging and is not cause for concern.
Note:Your vehicle may be equipped witha front air dam that can become damaged(due to reduced ground clearance) whentaking your vehicle off-road. This air damcan be taken off by removing two bolts.
Four-wheel drive vehicles are speciallyequipped for driving on sand, snow, mudand rough terrain and have operatingcharacteristics that are somewhatdifferent from conventional vehicles, bothon and off the road.
Power is supplied to all four wheelsthrough a transfer case. On four-wheeldrive vehicles, the transfer case allows youto select 4WD when necessary.Information on transfer case operation andshifting procedures can be found in thischapter. Information on transfer casemaintenance can be found in theMaintenance chapter. You should becomethoroughly familiar with this informationbefore you operate your vehicle.

Trailer Brake Effort Setting
The trailer brake controller allows the userto customize how aggressively the trailerbrakes engage. The default value is "Low"and is the recommended setting for mosttrailers. If your trailer's brakes require moreinitial voltage, or if you prefer moreaggressive trailer braking, then select eitherthe "Medium" or the "High" setting. SeeInformation Displays (page 89).
Procedure for Adjusting Gain
Note:Only perform this procedure in atraffic-free environment at speeds ofapproximately 20-25 mph (30-40 km/h).
The gain setting adjusts the trailer brakecontroller for the specific towing condition.You should change the setting as towingconditions change. Changes to towingconditions include trailer load, vehicle load,road conditions and weather.
The gain should be set to provide themaximum trailer braking assistance whilemaking sure the trailer wheels do not lockwhen using the brakes. Locked trailerwheels may lead to trailer instability.
1.Make sure the trailer brakes are in goodworking condition, functioning normallyand properly adjusted. See your trailerdealer if necessary.
2. Hook up the trailer and make theelectrical connections according to thetrailer manufacturer's instructions.
3. When you plug in a trailer with electricor electric-over-hydraulic brakes,TRAILER CONNECTED appears inthe information display.
4. Use the gain adjustment (+ and -)buttons to increase or decrease thegain setting to the desired startingpoint. A gain setting of 6.0 is a goodstarting point for heavier loads.
5. In a traffic-free environment, tow thetrailer on a dry, level surface at a speedof 20-25 mph (30-40 km/h) andsqueeze the manual control levercompletely.
6. If the trailer wheels lock up, indicatedby squealing tires, reduce the gainsetting. If the trailer wheels turn freely,increase the gain setting. Repeat Steps5 and 6 until the gain setting is at apoint just below trailer wheel lock-up.If towing a heavier trailer, trailer wheellock-up may not be attainable evenwith the maximum gain setting of 10.
Information Display Warning Messages
Note:An authorized dealer can diagnosethe trailer brake controller to determineexactly which trailer fault has occurred.However, your Ford warranty does not coverthis diagnosis if the fault is with the trailer.
TRAILER BRAKE MODULE FAULT
Displays in response to faults sensed bythe trailer brake controller, accompaniedby a single tone. If this message appears,contact an authorized dealer as soon aspossible for diagnosis and repair. Thecontroller may still function, but withdegraded performance.
WIRING FAULT ON TRAILER
Displays when there is a short circuit onthe electric brake output wire.
If this message displays, with no trailerconnected, the problem is with your vehiclewiring or trailer brake controller. Contactan authorized dealer.

TOWING POINTS
WARNINGS
Using recovery hooks is dangerousand should only be done by a personfamiliar with proper vehicle recoverysafety practices. Improper use of recoveryhooks may cause hook failure or separationfrom the vehicle and could result in seriousinjury or death.
Always slowly remove the slack fromthe recovery strap prior to pulling.Failure to do so can introducesignificantly higher loads which can causethe recovery hooks to break off, or therecovery strap to fail which can causeserious injury or death.
Never link two straps together witha clevis pin. These heavy metalobjects could become projectiles ifthe strap breaks and can cause seriousinjury or death.
Your vehicle comes equipped withframe-mounted front recovery hooks.These hooks should never have a loadapplied to them greater than the grossvehicle weight rating of your vehicle.
Before using recovery hooks:
•Make sure all attaching points aresecure and capable of withstandingthe applied load.
•Never use chains, cables or tow strapswith metal hook ends.
•Only use recovery straps that have aminimum breaking strength two tothree times the gross vehicle weight ofthe stuck vehicle.
•Make sure the recovery strap is in goodcondition and free of visible cuts, tearsor damage.
•Use a damper device such as a tarp,heavy blanket or piece of carpetdraped over the recovery strap to helpabsorb the energy in the event thestrap breaks.
•Make sure the stuck vehicle is notloaded heavier than its gross vehicleweight rating specified on thecertification label.
•Always align the tow vehicle and stuckvehicle in a straight line (within 10degrees).
•Keep bystanders to the sides of thevehicle, at a distance of at least twicethe length of the recovery strap. Thishelps avoid injury from the hazard of arecovery hook or strap breaking, or avehicle lurching into their path.

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).
ECONOMICAL DRIVING
Your fuel economy is affected by severalthings, such as how you drive, theconditions you drive under, and how youmaintain your vehicle.
You may improve your fuel economy bykeeping these things in mind:
•Accelerate and slow down in a smooth,moderate fashion.
•Drive at steady speeds withoutstopping.
•Anticipate stops; slowing down mayeliminate the need to stop.
•Combine errands and minimizestop-and-go driving.
•Close the windows for high-speeddriving.
•Drive at reasonable speeds (travelingat 55 mph [88 km/h] uses 15% lessfuel than traveling at 65 mph [105km/h]).
•Keep the tires properly inflated and useonly the recommended size.
•Use the recommended engine oil.
•Perform all regularly scheduledmaintenance.
Avoid these actions; they reduce your fueleconomy:
•Sudden accelerations or hardaccelerations.
•Revving the engine before turning it off.
•Idle for periods longer than one minute.
•Warm up your vehicle on coldmornings.
•Use the air conditioner or frontdefroster.
•Use the speed control in hilly terrain.
•Rest your foot on the brake pedal whiledriving.
•Drive a heavily loaded vehicle or tow atrailer.
•Carry unnecessary weight(approximately 1 mpg [0.4 km/L] islost for every 400 lb [180 kilogram] ofweight carried).
•Driving with the wheels out ofalignment.
Conditions
•Heavily loading a vehicle or towing atrailer may reduce fuel economy at anyspeed.
•Adding certain accessories to yourvehicle (for example bug deflectors,rollbars, light bars, running boards, skiracks or luggage racks) may reducefuel economy.
•To maximize the fuel economy, drivewith the tonneau cover installed (ifequipped).
•Using fuel blended with alcohol maylower fuel economy.
•Fuel economy may decrease with lowertemperatures during the first 8–10miles (12–16 kilometers) of driving.

What You Should Know About Fail-Safe Cooling
If the engine coolant supply is depleted,this feature allows the vehicle to be driventemporarily before incremental componentdamage is incurred. The “fail-safe”distance depends on ambienttemperatures, vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the enginecoolant temperature gauge will move tothe red (hot) area and:
The coolant temperaturewarning light will illuminate.
The service engine soonindicator will illuminate.
If the engine reaches a presetover-temperature condition, the enginewill automatically switch to alternatingcylinder operation. Each disabled cylinderacts as an air pump and cools the engine.
When this occurs the vehicle will stilloperate. However:
•The engine power will be limited.
•The air conditioning system will bedisabled.
Continued operation will increase theengine temperature and the engine willcompletely shut down, causing steeringand braking effort to increase.
Once the engine temperature cools, theengine can be re-started. Take your vehicleto an authorized dealer as soon as possibleto minimize engine damage.
When Fail-Safe Mode Is Activated
WARNINGS
Fail-safe mode is for use duringemergencies only. Operate thevehicle in fail-safe mode only as longas necessary to bring the vehicle to rest ina safe location and seek immediate repairs.When in fail-safe mode, the 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.
Never remove the coolant reservoircap while the engine is running or hot.
You have limited engine power when in thefail-safe mode, so drive the vehicle withcaution. The vehicle will not be able tomaintain high-speed operation and theengine will run rough. Remember that theengine is capable of completely shuttingdown automatically to prevent enginedamage, therefore:
1. Pull off the road as soon as safelypossible and turn off the engine.
2. Arrange for the vehicle to be taken toan authorized dealer.
3. If this is not possible, wait a shortperiod for the engine to cool.
4. Check the coolant level and replenishif low.
5. Re-start the engine and take yourvehicle to an authorized dealer.
Note:Driving the vehicle without repairingthe engine problem increases the chance ofengine damage. Take your vehicle to anauthorized dealer as soon as possible.

Maintenance

Engine Fluid TemperatureManagement (If Equipped)
WARNINGS
To reduce the risk of collision andinjury, be prepared that the vehiclespeed may reduce and the vehiclemay not be able to accelerate with fullpower until the fluid temperatures reduce.
Never remove the coolant reservoircap while the engine is running or hot.
Your vehicle has been designed to pull atrailer, but because of the added load, thevehicle’s engine may temporarily reachhigher temperatures during severeoperating conditions such as ascending along or steep grade while pulling a trailerin hot ambient temperatures.
At this time, you may notice your enginecoolant temperature gauge needle movetoward the H and the POWER REDUCEDTO LOWER TEMP message may appearin the information display.
You may notice a reduction in the vehicle’sspeed caused by reduced engine power.In order to manage the engine fluidtemperatures, your vehicle may enter thismode if certain high-temperature andhigh-load conditions take place. Theamount of speed reduction will depend onthe vehicle loading, towing, grade, ambienttemperature, and other factors. If thisoccurs, there is no need to pull off the road.The vehicle can continue to be driven whilethis message is active.
The air conditioning may turn on and offduring severe operating conditions toprotect the engine from overheating. Whenthe engine coolant temperature decreasesto a more normal operating temperature,the air conditioning will turn on once again.
If the engine coolant temperature gaugemoves fully into the red (hot) area, or if thecoolant temperature warning or serviceengine soon messages appear in yourinformation display:
1. Stop your vehicle as soon as safelypossible and shift the transmission intopark (P).
2. Leave the engine running until thecoolant temperature gauge needlemoves away from the H range. Afterseveral minutes, if this does nothappen, follow the remaining steps.
3.Switch the engine off and wait for it tocool before checking the coolant level.
4. If the coolant level is normal, you mayrestart your engine and continue on.
5. If the coolant is low, add coolant,restart the engine and take your vehicleto an authorized dealer. See Addingengine coolant in this chapter for moreinformation. Refer to fail-safe coolingfor additional information.
