Operating AWD Vehicles WithSpare Tires
A spare tire of a different size other thanthe tire provided should never be used. TheAWD system may disable automaticallyand enter front-wheel drive only mode toprotect driveline components if a non-fullsized tire is installed. This condition maydisplay an AWD OFF message in theinformation display. If there is an AWD OFFmessage in the information display fromusing a non-full sized spare tire, thisindicator should turn off after reinstallingthe repaired or replaced normal road tire
and cycling the ignition off and on. It isrecommended to reinstall the repaired orreplaced road tire as soon as possible.Major dissimilar tire sizes between the frontand rear axles (for example, 17 inch lowprofile tires on the front axle and 22 inchhigh profile tires on the rear axle) couldcause the AWD system to stop functioningand default to front-wheel drive or damagethe AWD system.

If Your Vehicle Goes Off the Edge of thePavement
•If your vehicle goes off the edge of thepavement, slow down, but avoid severebrake application, ease the vehicleback onto the pavement only afterreducing your speed. Do not turn thesteering wheel too sharply whilereturning to the road surface.
•It may be safer to stay on the apron orshoulder of the road and slow downgradually before returning to thepavement. You may lose control if youdo not slow down or if you turn thesteering wheel too sharply or abruptly.
•It often may be less risky to strike smallobjects, such as highway reflectors,with minor damage to your vehiclerather than attempt a sudden return tothe pavement which could cause thevehicle to slide sideways out of controlor rollover. Remember, your safety andthe safety of others should be yourprimary concern.
If Your Vehicle Gets Stuck
WARNINGS
Always fully apply the parking brakeand make sure you shift into park (P).Switch the ignition off and removethe key whenever you leave your vehicle.
If the parking brake is fully released,but the brake warning lamp remainsilluminated, the brakes may not beworking properly. Have your vehiclechecked as soon as possible.
Do not spin the wheels at over34 mph (55 km/h). The tires may failand injure a passenger or bystander.
Note:Do not rock the vehicle if the engineis not at normal operating temperature ordamage to the transmission may occur.
Note:Do not rock the vehicle for more thana few minutes or damage to thetransmission and tires may occur or theengine may overheat.
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.
If your vehicle is equipped withAdvanceTrac® with Roll StabilityControl™, it may be beneficial todisengage the AdvanceTrac® with RollStability Control™ system whileattempting to rock the vehicle.
Emergency Maneuvers
•In an unavoidable emergency situationwhere a sudden sharp turn must bemade, remember to avoid"over-driving" your vehicle (that is, turnthe steering wheel only as rapidly andas far as required to avoid theemergency). Excessive steering willresult in less vehicle control, not more.Additionally, smooth variations of theaccelerator and/or brake pedalpressure should be utilized if changesin vehicle speed are called for. Avoidabrupt steering, acceleration or brakingwhich could result in an increased riskof loss of vehicle control, vehiclerollover and/or personal injury. Use allavailable road surface to return thevehicle to a safe direction of travel.
•In the event of an emergency stop,avoid skidding the tires and do notattempt any sharp steering wheelmovements.
•If the vehicle goes from one type ofsurface to another (that is, fromconcrete to gravel) there will be achange in the way the vehicle respondsto a maneuver (steering, accelerationor braking). Again, avoid these abruptinputs.

Sand
Most of the time traction control improvestire traction by managing wheel slipthrough Brake, Engine, and AWDcalibrations. However, during low speeddriving, disabling traction control in deepsand can help keep the wheels moving tomaintain vehicle momentum.
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 slowlyand avoid spinning the wheels.
Do not drive your vehicle in deep sand foran extended period of time. This couldcause the AWD system to overheat anddefault to front-wheel drive. If this occurs,an AWD OFF message displays in theinformation display. To resume normalAWD function as soon as possible, stopthe vehicle in a safe location and stop theengine for at least 10 minutes. After theengine has been restarted and the AWDsystem has adequately cooled, the AWDOFF message turns off and normal AWDfunction returns. In the event the engine isnot stopped, the AWD OFF message turnsoff when the system cools and normalAWD function returns.
When driving at slow speeds in deep sandunder high outside temperatures, use L(Low) gear when possible. L (Low) gearoperation will maximize the engine andtransmission cooling capability.
Under severe operating conditions, the A/Cmay cycle on and off to protectoverheating of the engine.
Avoid excessive speed because vehiclemomentum can work against you andcause the vehicle to become stuck to thepoint that assistance may be required fromanother vehicle. Remember, you may beable to back out the way you came if youproceed with caution.
Mud and Water
If you must drive through high water, driveslowly. Traction or brake capability maybe limited.
When driving through water, determine thedepth; avoid water higher than the bottomof the wheel rims (for cars) or the bottomof the hubs (for trucks) (if possible) andproceed slowly. If the ignition system getswet, the vehicle 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 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.
Note:Driving through deep water maydamage the transmission.
If the front or rear axle is submerged inwater, have the power transfer unit (PTU)or rear axle serviced by an authorizeddealer.

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.
Avoid sudden braking as well. Although anAWD vehicle may accelerate better thana two-wheel drive vehicle in snow and ice,it won’t stop any faster, because as in othervehicles, braking occurs at all four wheels.Do not become overconfident as to roadconditions.
Make sure you allow sufficient distancebetween you and other vehicles forstopping. Drive slower than usual andconsider using one of the lower gears. Inemergency stopping situations, apply thebrake steadily. Since your vehicle isequipped with a four wheel (ABS), do not“pump” the brakes. See Hints on DrivingWith Anti-Lock Brakes (page 164).
Maintenance and Modifications
The suspension and steering systems onyour vehicle have been designed andtested to provide predictable performancewhether loaded or empty and durable loadcarrying capability. For this reason, FordMotor Company strongly recommends thatyou do not make modifications such asadding or removing parts (such as loweringkits or stabilizer bars) or by usingreplacement parts not equivalent to theoriginal factory equipment.
Any modifications to a vehicle that raisethe center of gravity can make it more likelythe vehicle will rollover as a result of a lossof control. Ford Motor Companyrecommends that caution be used withany vehicle equipped with a high load ordevice (such as ladder or luggage racks).
Failure to maintain your vehicle properlymay void the warranty, increase your repaircost, reduce vehicle performance andoperational capabilities and adverselyaffect driver and passenger safety.Frequent inspection of vehicle chassiscomponents is recommended if the vehicleis subjected to off-highway usage.

GENERAL INFORMATION
Note:Occasional brake noise is normal. Ifa metal-to-metal, continuous grinding orcontinuous squeal sound is present, thebrake linings may be worn-out. Have thesystem checked by an authorized dealer. Ifyour vehicle has continuous vibration orshudder in the steering wheel while braking,have it checked by an authorized dealer.
Note:Brake dust may accumulate on thewheels, even under normal drivingconditions. Some dust is inevitable as thebrakes wear and does not contribute tobrake noise. See Cleaning the Wheels(page 264).
Note:Depending on applicable laws andregulations in the country for which yourvehicle was originally built, your brake lampsmay flash during heavy braking. Followingthis, your hazard lights may also flash whenyour vehicle comes to a stop.
See Warning Lamps andIndicators (page 85).
Wet brakes result in reduced brakingefficiency. Gently press the brake pedal afew times when driving from a car wash orstanding water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedalbecomes stuck or entrapped, apply steadyand firm pressure to the brake pedal toslow the vehicle and reduce engine power.If you experience this condition, apply thebrakes and bring your vehicle to a safestop. Move the transmission to park (P),switch the engine off and apply the parkingbrake. Inspect the accelerator pedal forany interference. If none are found and thecondition persists, have your vehicle towedto the nearest authorized dealer.
Brake Assist
Brake assist detects when you brakerapidly by measuring the rate at which youpress the brake pedal. It providesmaximum braking efficiency as long as youpress the pedal, and can reduce stoppingdistances in critical situations.
Anti-lock Brake System
This system helps you maintain steeringcontrol during emergency stops by keepingthe brakes from locking.
This lamp momentarilyilluminates when you turn theignition on. If the light does notilluminate during start up, remains on orflashes, the system may be disabled. Havethe system checked by an authorizeddealer. If the anti-lock brake system isdisabled, normal braking is still effective.
If the brake warning lampilluminates when you release theparking brake, have the systemchecked by an authorized dealer.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
Note:When the system is operating, thebrake pedal may pulse and may travelfurther. Maintain pressure on the brakepedal. You may also hear a noise from thesystem. This is normal.
The anti-lock braking system will noteliminate the risks when:
•You drive too closely to the vehicle infront of you.
•Your vehicle is hydroplaning.
•You take corners too fast.
•The road surface is poor.

PRINCIPLE OF OPERATION
The traction control system helps avoiddrive wheel spin and loss of traction.
If your vehicle begins to slide, the systemapplies the brakes to individual wheelsand, when needed, reduces engine powerat the same time. If the wheels spin whenaccelerating on slippery or loose surfaces,the system reduces engine power in orderto increase traction.
USING TRACTION CONTROL
WARNING
The stability and traction controllight illuminates steadily if thesystem detects a failure. Make sureyou did not manually disable the tractioncontrol system using the informationdisplay controls or the switch. If thestability control and traction control lightis still illuminating steadily, have thesystem serviced by an authorized dealerimmediately. Operating your vehicle withthe traction control disabled could lead toan increased risk of loss of vehicle control,vehicle rollover, personal injury and death.
The system automatically turns on eachtime you switch the ignition on.
If your vehicle is stuck in mud or snow,switching traction control off may bebeneficial as this allows the wheels to spin.
Note:When you switch traction control off,stability control remains fully active.
Switching the System Off
When you switch the system off or on, amessage appears in the informationdisplay showing system status.
You can switch the system off by eitherusing the information display controls orthe switch.

PRINCIPLE OF OPERATION
WARNINGS
To help avoid personal injury, pleaseread and understand the limitationsof the system as contained in thissection. Sensing is only an aid for some(generally large and fixed) objects whenmoving on a flat surface at parking speeds.Certain objects with surfaces that absorbultrasonic waves, surrounding vehicle'sparking aid systems, traffic controlsystems, fluorescent lamps, inclementweather, air brakes, and external motorsand fans may also affect the function ofthe sensing system; this may includereduced performance or a false activation.
To help avoid personal injury, alwaysuse caution when in reverse (R) andwhen using the sensing system.
This system is not designed toprevent contact with small or movingobjects. The system is designed toprovide a warning to assist the driver indetecting large stationary objects to avoiddamaging your vehicle. The system maynot detect smaller objects, particularlythose close to the ground.
Certain add-on devices such as largetrailer hitches, bike or surfboard racksand any device that may block thenormal detection zone of the system, maycreate false beeps.
Note:Keep the sensors, located on thebumper or fascia, free from snow, ice andlarge accumulations of dirt. If the sensorsare covered, the system’s accuracy can beaffected. Do not clean the sensors withsharp objects.
Note:If your vehicle sustains damage tothe bumper or fascia, leaving it misalignedor bent, the sensing zone may be alteredcausing inaccurate measurement ofobstacles or false alarms.
Note:The sensing system cannot be turnedoff when a MyKey is present. See Principleof Operation (page 51).
Note:If you attach certain add-on devicessuch as a trailer or bike rack, the rear sensingsystem may detect that add-on device andtherefore provide warnings. It is suggestedthat you disable the rear sensing systemwhen you attach an add-on device to yourvehicle to prevent these warnings.
The sensing system warns the driver ofobstacles within a certain range of yourvehicle. The system turns on automaticallywhenever you switch the ignition on.
You can turn the system on oroff by pressing the parking aidbutton. If your vehicle does nothave a parking aid button, the system canbe switched off through the informationdisplay menu or from the pop-up messagethat appears once you shift thetransmission into reverse (R). See GeneralInformation (page 89).
If a fault is present in the system, a warningmessage appears in the informationdisplay. See Information Messages(page 98).
REAR PARKING AID
The rear sensors are only active when thetransmission is in reverse (R). As yourvehicle moves closer to the obstacle, therate of the audible warning increases.When the obstacle is less than 12 in(30 cm) away, the warning soundscontinuously. If the system detects astationary or receding object farther than12 in (30 cm) from the corners of thebumper, the tone sounds for only threeseconds. Once the system detects anobject approaching, the warning soundsagain.

The system may not operate correctly inany of the following conditions:
•You use a spare tire or a tiresignificantly worn more than the othertires.
•One or more tires are improperlyinflated.
•You try to park on a tight curve.
Do not use the system if:
•You have attached a bike rack, traileror other object near the sensors on thefront or rear of your vehicle.
•You have attached an overhangingobject (surfboard) to the roof.
•The front bumper or side sensors aredamaged or obstructed (front bumpercover).
•The correct tire size is not in use on yourvehicle (for example, a mini-spare tire).
Using Active Park Assist
Press the button to turn thesystem on or off.
When driving at a speed less than 22 mph(35 km/h), the system automatically scansboth sides of your vehicle for an availableparking space. The system displays amessage and a corresponding graphic toindicate it is searching for a parking space.Use the direction indicator to selectsearching either to the left hand side orright hand side of your vehicle. If thedirection indicator is not used, the systemdefaults to the passenger side of yourvehicle.
When the system finds a suitable space itdisplays a message and a tone sounds.Stop your vehicle and follow theinstructions on the display screen. If yourvehicle is moving very slowly, you mayneed to pull forward a short distancebefore the system is ready to park.
Note:You can also activate the systemafter you have already driven partially orcompletely past the parking space. To doso, press the active park assist button andthe system will inform you if you haverecently past a suitable parking space.
Note:You must observe that the selectedspace remains clear of obstructions at alltimes in the maneuver.

Note:Active park assist may not detectvehicles with overhanging loads (a bus or atruck), street furniture and other items. Youmust make sure the selected space issuitable for parking.
Note:You should drive your vehicle within5 ft (1.5 m) and as parallel to the othervehicles as possible while passing a parkingspace.
Note:The system always offers the lastdetected parking space (for example, if yourvehicle detects multiple spaces while youare driving, it offers the last one).
Note:If driven above approximately 22 mph(35 km/h), the display screen shows amessage to alert you to reduce your vehiclespeed.
Automatic Steering into ParkingSpace
Note:If vehicle speed exceeds 6 mph(10 km/h) or the maneuver is interrupted(driver input is detected), the systemswitches off and you need to take fullcontrol of your vehicle.
Note:If a maneuver is interrupted beforecompletion, the system switches off. Thesteering wheel position will not indicate theactualy position of the steering and you haveto take full control of your vehicle.
When you shift the transmission intoreverse (R), with your hands off the wheel(and nothing obstructing its movement),your vehicle steers itself into the space.The system displays instructions to moveyour vehicle back and forth in the space.
When you think your vehicle has enoughspace in front and behind it, or you hear asolid tone from the parking aid(accompanied by a touchscreen displaymessage and a chime), bring your vehicleto a complete stop.
When automatic steering is complete, thesystem displays a message and a chimesounds, indicating that the active parkassist process is finished. The driver isresponsible for checking the parking joband making any necessary correctionsbefore leaving your vehicle.
Deactivating the Park AssistFeature
Manually deactivate the system by:
•Pressing the active park assist buttonduring an active maneuver.
•Grabbing the steering wheel during anactive maneuver.
•Driving above approximately 22 mph(35 km/h) for 30 seconds during anactive park search.
•Driving above 6 mph (10 km/h) duringautomatic steering.
•Turning off the traction control system.
