All-Wheel Drive Messages
Action / DescriptionAWD Messages
Displays when the system automatically disables to protect itself. Thismay be caused by operating the vehicle with the compact tire installed,if the system is overheating or if there is an issue with another vehiclesystem preventing AWD operation. The system resumes normaloperation and clears this message after cycling the ignition on andoff and driving a short distance with the road tire re-installed, afterthe system is allowed to cool or after the other vehicle system issuesare resolved.
AWD OFF
Displays in conjunction with the powertrain malfunction or reducedpower light when the system is not operating properly. If the messagestays on or continues to come on, contact your authorized dealer assoon as possible.

Operating AWD Vehicles With Spareor Mismatched Tires
WARNING: Only use replacement tiresand wheels that are the same size, loadindex, speed rating and type (such asP-metric versus LT-metric or all-seasonversus all-terrain) as those originally providedby Ford. The recommended tire and wheelsize may be found on either the SafetyCompliance Certification Label (affixed toeither the door hinge pillar, door-latch post,or the door edge that meets the door-latchpost, next to the driver’s seating position), orthe Tire Label which is located on the B-Pillaror edge of the driver’s door. If thisinformation is not found on these labels, thenyou should contact your authorized dealeras soon as possible. Use of any tire or wheelnot recommended by Ford can affect thesafety and performance of your vehicle,which could result in an increased risk of lossof vehicle control, vehicle rollover, personalinjury and death.
A spare tire of a different size other than thetire provided should never be used. TheAWD system may disable automatically andenter front-wheel drive only mode to protectdriveline components if a non-full sized tireis installed. This condition may display anAWD OFF message in the informationdisplay. If there is an AWD OFF message inthe information display from using a non-fullsized spare tire, this indicator should turn offafter reinstalling the repaired or replacednormal road tire and cycling the ignition offand on. It is recommended to reinstall therepaired or replaced road tire as soon aspossible.
Major dissimilar tire sizes between the frontand rear axles (for example, 17 inch lowprofile tires on the front axle and 22 inch highprofile tires on the rear axle) could cause theAWD system to stop functioning and defaultto front-wheel drive or damage the AWDsystem. However, the AWD system iscapable of tolerating any combination of newand worn tires of the same original tire size.For example, using 3 worn tread tires and 1new tread tire all of the same original tiresize, can be tolerated by the AWD system.
Driving In Special Conditions With All-Wheel Drive (AWD)
AWD vehicles are equipped for driving onsand, snow, mud and rough roads and haveoperating characteristics that are somewhatdifferent from conventional vehicles, both onand off the highway.
When driving at slow speeds in deep sandunder high outside temperatures, use a lowgear when possible. Lower gear operationwill maximize the engine and transmissioncooling capability.
Under severe operating conditions, the A/Cmay cycle on and off to protect overheatingof the engine.
Basic operating principles in specialconditions
•Drive slower in strong crosswinds whichcan affect the normal steeringcharacteristics of your vehicle.
•Be extremely careful when driving onpavement made slippery by loose sand,water, gravel, snow or ice.

acceleration or braking which could resultin an increased risk of loss of vehiclecontrol, vehicle rollover and/or personalinjury. Use all available road surface toreturn the vehicle to a safe direction oftravel.
•In the event of an emergency stop, avoidskidding the tires and do not attempt anysharp steering wheel movements.
•If the vehicle goes from one type ofsurface to another (that is, from concreteto gravel) there will be a change in theway the vehicle responds to a maneuver(steering, acceleration or braking). Again,avoid these abrupt inputs.
Sand
Most of the time traction control improvestire traction by managing wheel slip throughBrake, Engine, and AWD calibrations.However, during low speed driving, disablingtraction control in deep sand can help keepthe wheels moving to maintain vehiclemomentum.
When driving over sand, try to keep all fourwheels on the most solid area of the trail.Avoid reducing the tire pressures but shiftto a lower gear and drive steadily throughthe terrain. Apply the accelerator slowly andavoid spinning the wheels.
Do not drive your vehicle in deep sand foran extended period of time. This could causethe AWD system to overheat and default tofront-wheel drive. If this occurs, an AWD OFFmessage displays in the information display.To resume normal AWD function as soon aspossible, stop the vehicle in a safe locationand stop the engine for at least 10 minutes.After the engine has been restarted and theAWD system has adequately cooled, theAWD OFF message turns off and normalAWD function returns. In the event theengine is not stopped, the AWD OFFmessage turns off when the system coolsand normal AWD function returns.
When driving at slow speeds in deep sandunder high outside temperatures, use L (Low)gear when possible. L (Low) gear operationwill maximize the engine and transmissioncooling capability.
Under severe operating conditions, the A/Cmay cycle on and off to protect overheatingof the engine.
Avoid excessive speed because vehiclemomentum can work against you and causethe vehicle to become stuck to the point thatassistance may be required from anothervehicle. Remember, you may be able to backout the way you came if you proceed withcaution.
Mud and Water
If you must drive through high water, driveslowly. Traction or brake capability may belimited.
When driving through water, determine thedepth; avoid water higher than the bottomof the wheel rims (for cars) or the bottom ofthe hubs (for trucks) (if possible) and proceedslowly. If the ignition system gets wet, thevehicle may stall.

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 AWD vehicles can lose tractionin slick mud. As when you are driving oversand, apply the accelerator slowly and avoidspinning your wheels. If the vehicle doesslide, steer in the direction of the slide untilyou regain control of the vehicle.
After driving through mud, clean off residuestuck to rotating driveshafts and tires. Excessmud stuck on tires and rotating driveshaftscauses an imbalance that could damagedrive components.
Note:Driving through deep water maydamage the transmission.
If the front or rear axle is submerged in water,have the power transfer unit (PTU) or rearaxle serviced by an authorized dealer.
Driving on Hilly or Sloping Terrain
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 will use.Do not drive over the crest of a hill withoutseeing what conditions are on the other side.Do not drive in reverse over a hill withoutthe aid of an observer.
Although natural obstacles may make itnecessary to travel diagonally up or down ahill or steep incline, you should always try todrive straight up or straight down.
When climbing a steep slope or hill, start ina lower gear rather than downshifting to alower 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 turnaroundbecause 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 will cause thetires to slip, spin or lose traction, resulting inloss of vehicle control.
Descend a hill in the same gear you woulduse to climb up the hill to avoid excessivebrake application and brake overheating. Donot descend in neutral; instead, disengageoverdrive or manually shift to a lower gear.When descending a steep hill, avoid suddenhard braking as you could lose control. Thefront wheels have to be turning in order tosteer the vehicle.

Press and release to decrease theset speed in small increments.
Press and hold either button to change theset speed in large increments. Release thebutton when you reach your preferred speed.
Press the accelerator or brake pedal untilyou reach your preferred speed. Press eitherbutton.
The system may apply the brakes to slowthe vehicle to the new set speed. The setspeed displays continuously in theinformation display when the system isactive.
Canceling the Set Speed
Press and release the button or tapthe brake pedal.
Note:The system remembers the set speed.
Resuming the Set Speed
Press and release the button.
Your vehicle speed returns to the previouslyset speed and gap setting. The set speeddisplays continuously in the informationdisplay when the system is active.
Note:Only use resume if you are aware ofthe set speed and intend to return to it.
Automatic Cancellation
Automatic cancellation can also occur when:
•The tires lose traction.
•You apply the parking brake.
Park Brake Application
Automatic parking brake application andcancellation occurs if:
•You unbuckle the seatbelt and open thedoor after you stop the vehicle.
•You hold the vehicle at a stopcontinuously for more than three minutes.
Hilly Condition Usage
You should select a lower gear when thesystem is active in situations such asprolonged downhill driving on steep grades,for example in mountainous areas. Thesystem needs additional engine braking inthese situations to reduce the load on thevehicle’s regular brake system to prevent itfrom overheating.
Note:An audible alarm sounds and thesystem shuts down if it applies brakes for anextended period of time. This allows thebrakes to cool. The system functionsnormally again after the brakes cool.
Switching Adaptive Cruise Control Off
For vehicles without Speed Limiter,press and release the button whenthe system is in standby mode orswitch the ignition off.
For vehicles with Speed Limiter,press and release the button whenthe system is in standby mode orswitch the ignition off.

Note:The system turns on each time youswitch the ignition on and you shift intoreverse (R). If you temporarily switch thesystem off, it turns on the next time youswitch the ignition on.
Note:The system may not correctly operatewhen towing a trailer. For vehicles with atrailer tow module and tow bar approved byus, the system turns off when you attach atrailer. For vehicles with an aftermarkettrailer tow module or tow bar, werecommend that you switch the system offwhen you attach a trailer.
To permanently switch the system off,contact an authorized dealer.
STEERING
Electric Power Steering
WARNING: The electric power steeringsystem has diagnostic checks thatcontinuously monitor the system. If a fault isdetected, a message displays in theinformation display. Stop your vehicle assoon as it is safe to do so. Switch the ignitionoff. After at least 10 seconds, switch theignition on and watch the information displayfor a steering system warning message. If asteering system warning message returns,have the system checked by an authorizeddealer.
WARNING: If the system detects anerror, you may not feel a difference in thesteering, however a serious condition mayexist. Obtain immediate service from anauthorized dealer, failure to do so may resultin 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 to thesteering system. You do not lose the abilityto steer your vehicle manually. Typicalsteering and driving maneuvers allow thesystem to cool and return to normaloperation.
Steering Tips
If the steering wanders or pulls, check for:
•Correct tire pressures.
•Uneven tire wear.
•Loose or worn suspension components.
•Loose or worn steering components.
•Improper vehicle alignment.

Driving Aids

Maintain coolant concentration within 48%to 50%, which equates to a freeze pointbetween -30°F (-34°C) and -34°F (-37°C).Coolant concentration should be checkedusing a refractometer. We recommend,Robinair® Coolant and Battery Refractometer75240 (Rotunda tool part number:ROB75240). We do not recommend the useof hydrometers or coolant test strips formeasuring coolant concentration.
Note: Automotive fluids are notinterchangeable. Do not use coolant orwindshield washer fluid outside of itsspecified function and vehicle location.
Note: Do not use stop leak pellets, coolingsystem sealants, or non-specified additivesas they can cause damage to the enginecooling or heating systems. Resultingcomponent damage may not be covered bythe vehicle Warranty.
Adding Coolant
WARNING: Do not add engine coolantwhen the engine is hot. Failure to follow thisinstruction could result in personal injury.
WARNING: Do not remove the coolantreservoir cap when the cooling system is hot.Wait 10 minutes for the cooling system tocool down. Cover the coolant reservoir capwith a thick cloth to prevent the possibilityof scalding and slowly remove the cap.Failure to follow this instruction could resultin personal injury.
It is very important to use prediluted coolantmeeting the correct specification in order toavoid plugging the small passageways in theengine cooling system. See Capacities andSpecifications (page 373). Incorrectprediluted coolant use can cause damagenot covered by the vehicle Warranty.
If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
To top up the coolant level do the following:
1. Unscrew the cap slowly. Any pressureescapes as you unscrew the cap.
2. Add prediluted coolant meeting thecorrect specification. See Capacities andSpecifications (page 366).
3.Add enough prediluted coolant to reachthe 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.
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.
Do not mix different colors or types ofprediluted coolant in your vehicle. Mixing ofprediluted coolant or using an incorrectprediluted coolant may harm the engine orcooling system components and may not becovered by the vehicle Warranty.
In case of emergency, you can add a largeamount of water without engine coolant inorder to reach a vehicle service location. Inthis instance, qualified personnel:

Maintenance

1. Must drain the cooling system.
2. Chemically clean the cooling system.
3. Refill with prediluted coolant as soon aspossible.
Water alone, without prediluted 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 of thecoolant.
Recycled Coolant
We do not recommend the use of recycledcoolant as an approved recycling process isnot yet available.
Dispose of used engine coolant in anappropriate manner. Follow yourcommunity's regulations and standards forrecycling and disposing of automotive fluids.
Severe Climates
If you drive in extremely cold climates:
•It may be necessary to increase thecoolant concentration above 50%.
•A coolant concentration of 60% providesimproved freeze point protection. Coolant concentrations above 60%decrease the overheat protectioncharacteristics of the coolant and maycause engine damage.
If you drive in extremely hot climates:
•It may be necessary to decrease thecoolant concentration to 40%.
•A coolant concentration of 40% providesimproved overheat protection. Coolantconcentrations below 40% decrease thefreeze and corrosion protectioncharacteristics of the coolant and maycause engine damage.
Vehicles driven year-round in non-extremeclimates should use prediluted coolant foroptimum cooling system and engineprotection.
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 coolanttemperature gauge moves toward the redzone:
