Once through water, always try the brakes.Wet brakes do not stop the vehicle aseffectively as dry brakes. Drying can beimproved by moving your vehicle slowlywhile applying light pressure on the brakepedal.
Be cautious of sudden changes in vehiclespeed or direction when you are driving inmud. Even 4WD vehicles can lose tractionin slick mud. As when you are driving oversand, apply the accelerator slowly andavoid spinning your wheels. If the vehicledoes slide, steer in the direction of the slideuntil you regain control of the vehicle.
After driving through mud, clean off residuestuck to rotating driveshafts and tires.Excess mud stuck on tires and rotatingdriveshafts causes an imbalance thatcould damage drive components.
“Tread Lightly” is an educational programdesigned to increase public awareness ofland-use regulations and responsibilitiesin our nations wilderness areas. Ford MotorCompany joins the U.S. Forest Service andthe Bureau of Land Management inencouraging you to help preserve ournational forest and other public and privatelands by “treading lightly.”
Driving on Hilly or Sloping Terrain
Although natural obstacles could make itnecessary to travel diagonally up or downa hill or steep incline, you should alwaystry to drive straight up or straight down.
Note: Avoid driving crosswise or turning onsteep slopes or hills. A danger lies in losingtraction, slipping sideways and possiblyrolling over. Whenever driving on a hill,determine beforehand the route you willuse. Do not drive over the crest of a hillwithout seeing what conditions are on theother side. Do not drive in reverse over a hillwithout the aid of an observer.
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 you do stall out, do not try to turn aroundbecause you might roll over. It is better toback down to a safe location.
Apply just enough power to the wheels toclimb the hill. Too much power can 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; instead,disengage overdrive or manually shift to alower gear. When descending a steep hill,avoid sudden hard braking as you couldlose control. The front wheels have to beturning in order to steer the vehicle.

WARNING: Pay close attention tochanging road conditions such asentering or leaving a highway, on roadswith intersections or roundabouts, roadswithout visible lanes of travel, roads thatare winding, slippery, unpaved, or steepslopes.
WARNING: The system does notcontrol speed in low traction conditionsor extremely steep slopes. The systemis designed to be an aid and does notrelieve you of your responsibility to drivewith due care and attention. Failure tofollow this instruction could result inpersonal injury.
WARNING: The system is not acrash warning or avoidance system.
WARNING: Do not use the systemwhen towing a trailer that hasaftermarket electronic trailer brakecontrols. Failure to follow this instructioncould result in the loss of control of yourvehicle, personal injury or death.
WARNING: Do not use tire sizesother than those recommended becausethis can affect the normal operation ofthe system. Failure to do so may resultin a loss of vehicle control, which couldresult in serious injury.
WARNING: Do not use the systemwith a snow plow blade installed.
WARNING: Do not use the systemin poor visibility, for example fog, heavyrain, spray or snow.
When Following a Vehicle
WARNING: When following avehicle that is braking, your vehicle doesnot always decelerate quickly enough toavoid a crash without driver intervention.Apply the brakes when necessary. Failureto follow this instruction could result inpersonal injury or death.
Hilly Condition Usage
You should select a lower gear when thesystem is active in situations such asprolonged downhill driving on steepgrades, for example in mountainous areas.The system needs additional enginebraking in these situations to reduce theload on the vehicle’s regular brake systemto prevent it from overheating.
Note:An audible alarm sounds and thesystem shuts down if it applies brakes foran extended period of time. This allows thebrakes to cool. The system functionsnormally again after the brakes cool.
ADAPTIVE CRUISE CONTROL
LIMITATIONS - VEHICLES

STEERING
Electric Power Steering
WARNING: The electric powersteering system has diagnostic checksthat continuously monitor the system. Ifa fault is detected, a message displaysin the information display. Stop yourvehicle as soon as it is safe to do so.Switch the ignition off. After at least 10seconds, switch the ignition on andwatch the information display for asteering system warning message. If asteering system warning messagereturns, have the system checked assoon as possible.
WARNING: If the system detectsan error, you may not feel a difference inthe steering, however a serious conditionmay exist. Have your vehicle checked assoon as possible. Failure to do so mayresult in loss of steering control.
Your vehicle has an electric power steeringsystem, there is no fluid reservoir, nomaintenance is required.
If your vehicle loses electrical power whileyou are driving, electric power steeringassistance is lost. The steering system stilloperates and you can steer your vehiclemanually. Manually steering your vehiclerequires more effort.
Extreme continuous steering may increasethe effort required for you to steer yourvehicle, this increased effort preventsoverheating and permanent damage tothe steering system. You do not lose theability to steer your vehicle manually.Typical steering and driving maneuversallow the system to cool and return tonormal operation.
Steering Tips
If the steering wanders or pulls, check for:
•Correct tire pressures.
•Uneven tire wear.
•Loose or worn suspensioncomponents.
•Loose or worn steering components.
•Improper vehicle alignment.
Note:A high crown in the road or highcrosswinds may also make the steeringseem to wander or pull.
Adaptive Learning (If Equipped)
The electronic power steering systemadaptive learning helps correct roadirregularities and improves overall handlingand steering feel. It communicates withthe brake system to help operateadvanced stability control and accidentavoidance systems. Additionally, wheneverthe battery is disconnected or a newbattery installed, you must drive yourvehicle a short distance before the systemrelearns the strategy and reactivates allsystems.
PRE-COLLISION ASSIST
WARNING: You are responsible forcontrolling your vehicle at all times. Thesystem is designed to be an aid and doesnot relieve you of your responsibility todrive with due care and attention. Failureto follow this instruction could result inthe loss of control of your vehicle,personal injury or death.

REDUCED ENGINE
PERFORMANCE
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 coolant temperature gaugeneedle moves to the upper limit position,the engine is overheating. See Gauges(page 104).
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 continues to operatewith limited power for a short period oftime.
If the engine temperature continues to rise,the fuel supply to the engine reduces. Theair conditioning switches off and the enginecooling fan operates continually.
1.Gradually reduce your speed and stopyour vehicle as soon as it is safe to doso.
2.Immediately switch the engine off toprevent severe engine damage.
3.Wait for the engine to cool down.
4.Check the coolant level. See EngineCoolant Check (page 324).
5.Have your vehicle checked as soon aspossible.
COLD WEATHER
PRECAUTIONS
The functional operation of somecomponents and systems can be affectedat temperatures below approximately-13°F (-25°C).
BREAKING-IN
Your vehicle requires a break-in period. Forthe first 1,000 mi (1,600 km), avoid drivingat high speeds, heavy braking, aggressiveshifting or using your vehicle to tow. Duringthis time, your vehicle may exhibit someunusual driving characteristics.
DRIVING ECONOMICALLY
The following helps to improve fuelconsumption:
•Drive smoothly, accelerate gently andanticipate the road ahead to avoidheavy braking.
•Regularly check your tire pressures andmake sure that they are inflated to thecorrect pressure.
•Follow the recommended maintenanceschedule and carry out therecommended checks.
•Plan your journey and check the trafficbefore you set off. It is more efficientto combine errands into a single tripwhenever possible.
•Avoid idling the engine in cold weatheror for extended periods. Start theengine only when you are ready to setoff.
•Do not carry unnecessary weight in yourvehicle as extra weight wastes fuel.

It is very important to use predilutedcoolant approved to the correctspecification in order to avoid plugging thesmall passageways in the engine coolingsystem. See Capacities andSpecifications (page 378). Do not mixdifferent colors or types of coolant in yourvehicle. Mixing of engine coolants or usingan incorrect coolant may harm the engineor cooling system components and maynot be covered by the vehicle Warranty.
Note:If prediluted coolant is not available,use the approved concentrated coolantdiluting it to 50/50 with distilled water. SeeCapacities and Specifications (page 378).Using water that has not been deionisedmay contribute to deposit formation,corrosion and plugging of the small coolingsystem passageways.
Note: Coolants marketed for all makes andmodels may not be approved to ourspecifications 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 (page378).
3.Add enough prediluted coolant toreach the correct level.
4.Replace the coolant reservoir cap. Turnthe cap clockwise until it contacts thehard stop.
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.
In case of emergency, you can add a largeamount of water without engine coolantin order to reach a vehicle service location.In this instance, qualified personnel:
1.Must drain the cooling system.
2.Chemically clean the coolant system.
3.Refill with engine coolant as soon aspossible.
Water alone, without engine coolant, cancause engine damage from corrosion,overheating or freezing.
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.
Note:Dispose of used coolant in theappropriate manner.
