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.

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 vehicle backonto the pavement only after reducingyour speed. Do not turn the steeringwheel too sharply while returning to theroad 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, withminor damage to your vehicle rather thanattempt a sudden return to the pavementwhich could cause the vehicle to slidesideways out of control or rollover.Remember, your safety and the safety ofothers should be your primary concern.
If Your Vehicle Gets Stuck
WARNING: Always set the parkingbrake fully and make sure you shift thegearshift lever to park (P). Switch the ignitionoff and remove the key whenever you leaveyour vehicle.
WARNING: If the parking brake is fullyreleased, but the brake warning lampremains illuminated, the brakes may not beworking properly. Have your vehicle checkedas soon as possible.
WARNING: Do not spin the wheels atover 34 mph (55 km/h). The tires may fail andinjure 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 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.
If your vehicle is equipped withAdvanceTrac® with Roll Stability Control™, itmay be beneficial to disengage theAdvanceTrac® with Roll Stability Control™system while attempting 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, turn the steeringwheel only as rapidly and as far asrequired to avoid the emergency).Excessive steering will result in lessvehicle control, not more. Additionally,smooth variations of the acceleratorand/or brake pedal pressure should beutilized if changes in vehicle speed arecalled for. Avoid abrupt steering,
186

All-Wheel Drive (If Equipped)
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.

Your vehicle has anti-lock brakes, thereforeapply the brakes steadily. Do not “pump” thebrakes.
Driving on Snow and Ice
WARNING: If you are driving in slipperyconditions that require tire chains or cables,then it is critical that you drive cautiously.Keep speeds down, allow for longer stoppingdistances and avoid aggressive steering toreduce the chances of a loss of vehiclecontrol which can lead to serious injury ordeath. If the rear end of your vehicle slideswhile cornering, steer in the direction of theslide until you regain control of your vehicle.
Note:Your vehicle may have originalequipment tires designed to optimize theperformance of your vehicle in dry or wetsummer road conditions. If your vehicle isequipped with such tires, we recommendusing a dedicated set (all 4 tires) of wintertires in snow and ice conditions. Do not mixwinter tires and performance tires betweenaxles or degraded traction and handlingcharacteristics could result.
Note:Excessive tire slippage can causedriveline damage.
AWD vehicles have advantages overtwo-wheel drive (2WD) 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 and ice.Apply the accelerator slowly and steadilywhen starting from a full stop.
Avoid sudden braking as well. Although anAWD vehicle may accelerate better than atwo-wheel drive vehicle in snow and ice, itwon’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 for stopping.Drive slower than usual and consider usingone of the lower gears. In emergencystopping situations, apply the brake steadily.Since your vehicle is equipped with a fourwheel (ABS), do not “pump” the brakes. SeeHints on Driving With Anti-Lock Brakes(page 193).
Maintenance and Modifications
The suspension and steering systems onyour vehicle have been designed and testedto provide predictable performance whetherloaded or empty and durable load carryingcapability. For this reason, Ford MotorCompany strongly recommends that you donot make modifications such as adding orremoving parts (such as lowering kits orstabilizer bars) or by using replacement partsnot equivalent to the original factoryequipment.
Any modifications to a vehicle that raise thecenter of gravity can make it more likely thevehicle will rollover as a result of a loss ofcontrol. Ford Motor Company recommendsthat caution be used with any vehicleequipped with a high load or device (suchas ladder or luggage racks).

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 326).
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 105).
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 pedal becomesstuck or entrapped, apply steady and firmpressure to the brake pedal to slow thevehicle and reduce engine power. If youexperience this condition, apply the brakesand bring your vehicle to a safe stop. Movethe transmission to park (P), switch theengine off and apply the parking brake. Inspect the accelerator pedal for anyinterference. If none are found and thecondition persists, have your vehicle towedto the nearest authorized dealer.
Brake Assist
Brake assist detects when you brake rapidlyby measuring the rate at which you press thebrake pedal. It provides maximum brakingefficiency as long as you press the pedal,and can reduce stopping distances in criticalsituations.
Anti-lock Brake System
This system helps you maintain steeringcontrol during emergency stops by keepingthe brakes from locking.
This lamp momentarily illuminateswhen you switch the ignition on. Ifthe light does not illuminate duringstart up, remains on or flashes, the systemmay be disabled. Have the system checkedby an authorized dealer. If the anti-lock brakesystem is disabled, normal braking is stilleffective.
If the brake warning lampilluminates when you release theparking brake, have the systemchecked by an authorized dealer. It alsoilluminates momentarily when you switch theignition on to confirm the lamp is functional.If it does not illuminate when you switch theignition on or begins to flash at any time,have the system checked by an authorizeddealer.

HINTS ON DRIVING WITH ANTI-
LOCK BRAKES
The anti-lock braking system does 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.
Note: If the system activates, the brakepedal may pulse and may travel further. Maintain pressure on the brake pedal. Youmay also hear a noise from the system. Thisis normal.
ELECTRIC PARKING BRAKE
WARNING: Always fully apply theparking brake and make sure you shift intopark (P). Failure to follow this instructioncould result in personal injury or death.
WARNING: If you drive extendeddistances with the parking brake applied,you could cause damage to the brakesystem.
WARNING: The electric parking brakedoes not operate if the vehicle battery isrunning out of charge.
Your vehicle has an electric parking brake.You operate it with a switch instead of alever. The switch is on the center console orto the left-hand side of the steering wheel,on the lower part of the instrument panel.
Note:The electric parking brake makesnoises during operation. This is normal.
Applying the Electric Parking Brake
Pull the switch upward.
The red warning lamp flashesduring operation and illuminateswhen the parking brake is applied.
Note:It remains illuminated for a shortperiod of time after you switch the ignitionoff.
If it continues to flash or does not illuminate,the system has malfunctioned. Have yourvehicle checked as soon as possible.
Note:You can apply the electric parkingbrake when the ignition is off.
Note:The electric parking brake couldautomatically apply when you shift into park(P). See Transmission (page 177).
Applying the Electric Parking Brake in anEmergency
Note:Do not apply the electric parking brakewhen your vehicle is moving, except in anemergency. If you repeatedly use the electricparking brake to slow or stop your vehicle,you could cause damage to the brakesystem.
You can use the electric parking brake toslow or stop your vehicle in an emergency.

PRINCIPLE OF OPERATION
WARNING: Vehicle modificationsinvolving braking system, aftermarket roofracks, suspension, steering system, tireconstruction and wheel and tire size maychange the handling characteristics of yourvehicle and may adversely affect theperformance of the electronic stability controlsystem. In addition, installing any stereoloudspeakers may interfere with andadversely affect the electronic stabilitycontrol system. Install any aftermarket stereoloudspeaker as far as possible from the frontcenter console, the tunnel, and the frontseats in order to minimize the risk ofinterfering with the electronic stability controlsensors. Reducing the effectiveness of theelectronic stability control system could leadto an increased risk of loss of vehicle control,vehicle rollover, personal injury and death.
WARNING: Remember that evenadvanced technology cannot defy the lawsof physics. It’s always possible to lose controlof a vehicle due to inappropriate driver inputfor the conditions. Aggressive driving on anyroad condition can cause you to lose controlof your vehicle increasing the risk of personalinjury or property damage. Activation of theelectronic stability control system is anindication that at least some of the tires haveexceeded their ability to grip the road; thiscould reduce the operator’s ability to controlthe vehicle potentially resulting in a loss ofvehicle control, vehicle rollover, personalinjury and death. If your electronic stabilitycontrol system activates, SLOW DOWN.
The system automatically turns on each timeyou switch the ignition on.
If a fault occurs in either the stability controlor the traction control system, you mayexperience the following conditions:
•The stability and traction control lightilluminates steadily.
•The stability control and traction controlsystems do not enhance your vehicle'sability to maintain traction of the wheels.
If a driving condition activates either thestability control or the traction control systemyou may experience the following conditions:
•The stability and traction control lightflashes.
•Your vehicle slows down.
•Reduced engine power.
•A vibration in the brake pedal.
•The brake pedal is stiffer than usual.
•If the driving condition is severe and yourfoot is not on the brake, the brake pedalmay move as the system applies higherbrake force.
The stability control system has severalfeatures built into it to help you maintaincontrol of your vehicle:
