Operating Four-Wheel Drive witha Spare or Worn Tires
Your four-wheel drive system is notintended to provide full function with tiresthat have different levels of wear or witha dissimilar spare tire. Incorrect use offour-wheel drive with such tires can causesystem damage.
If there is a difference in the level of wearamong tires on the vehicle or if you installa dissimilar spare tire on the vehicle, do notuse 4WD High or 4WD Low (if equipped)other than to get your vehicle unstuck.After getting your vehicle unstuck, shift to2H by performing the following steps:
1.Come to a stop on a flat, horizontalsurface
2.Shift the transmission to park (P) forautomatic transmissions and neutral(N) for manual transmissions.
3.Switch to two-wheel drive mode.
4.Shift the transmission to reverse (R).
5.Shift the transmission to drive (D) forautomatic transmissions and to firstgear for manual transmissions. Thisensures the transfer case system is nottrapped in place.
Mechanical Shift Blocking
On four-wheel drive vehicles with amechanically locked four-wheel drive highmode, the transfer case distributes torqueto the front wheels by mechanicallyinterlocking the front and rear driveshaftstogether. Various external factors affectshifting performance of this type of systemincluding, but not limited to:
•Vehicle acceleration.
•Dissimilar tire sizes.
•Steering input.
If the system detects a mechanical shiftblockage at speed after you selecttwo-wheel drive high, the message "4x4Unable to Disengage See Manual", coulddisplay momentarily. If this messagedisplays, one or more of the followingactions can relieve the mechanical shiftblock:
•Momentary acceleration.
•Momentary braking.
•Bringing the vehicle to a stop.
•Shifting the transmission to neutral andback to drive.
•Shifting the transmission to reverseand back to drive.
•Driving the vehicle around a tight turnat a slow speed.
SWITCHING FOUR-WHEEL
DRIVE ON AND OFF
A vehicle that comes with four-wheel drive,when selected, has the ability to use allfour wheels to power itself. This increasestraction, which may enable you to safelydrive over terrain and road conditions thata conventional two-wheel drive vehiclecannot.
On some four-wheel drive models, theinitial shift from two-wheel drive tofour-wheel drive while the vehicle ismoving can cause a momentary clunk andratcheting sound. These sounds are normalas the front drivetrain comes up to speedand are not cause for concern.

Note:Switching the electronic lockingdifferential off while turning results indisengagement difficulties. If the electroniclocking differential has difficultydisengaging, release the accelerator pedaland turn the steering wheel back and forthin small increments while maintainingcontrol and following a straight line.
Note:The electronic locking differential isfor off-road use only and is not for use ondry pavement. Using the electronic lockingdifferential on dry pavement results inincreased tire wear, noise and vibration.
Note:Do not perform this operation whencruise control or trail control is selected andactive. The system may not engage ordisengage as expected.

•Stand at a minimum of 12 ft(3.66 m) away from the wheeland tire assembly.
•Use both eye and earprotection.
Important: Remember to replacethe wheel valve stems when theroad tires are replaced on yourvehicle.
It is recommended that the twofront tires or two rear tiresgenerally be replaced as a pair ifthe worn tires still have usabledepth.
To avoid potential Four-WheelDrive (4WD) malfunction or(4WD) system damage, it isrecommended to replace all fourtires rather than mixing
significantly worn tires with newtires.
The tire pressure sensors mountedin the wheels (originally installedon your vehicle) are not designedto be used in aftermarket wheels.
The use of wheels or tires notrecommended may affect theoperation of your tire pressuremonitoring system.
If the tire pressure monitoringsystem indicator is flashing, yoursystem is malfunctioning. Yourreplacement tire might beincompatible with your tirepressure monitoring system, orsome component of the systemmay be damaged.
Tire can be damaged duringoff-road use, so inspection afteroff-road use is alsorecommended.
Replacing a Tire That IsGreenhouse Gas Certified
The tires installed on this vehicleat the factory as originalequipment are certified forGreenhouse Gas and FuelEfficiency regulations.Replacement tires must be ofequal or lower rolling resistancelevel (TRRL or Crr). Consult withyour tire supplier(s) forappropriate replacement tires.
USING SNOW CHAINS
WARNING: Do not exceed 30 mph(50 km/h). Failure to follow thisinstruction could result in the loss ofcontrol of your vehicle, personal injury ordeath.
WARNING: Do not use snow chainson snow-free roads.
WARNING: Only fit snow chains tospecified tires.
WARNING: If your vehicle is fittedwith wheel trims, remove them beforefitting snow chains.
WARNING: Wheels and tires mustbe the same size, load index and speedrating as those originally fitted on thevehicle. Use of any other tire or wheelcan affect the safety and performanceof your vehicle. Additionally, the use ofnon-recommended tires and wheels can

CHANGING A FLAT TIRE
If you get a flat tire when driving, do notapply the brake heavily. Instead, graduallydecrease your speed. Hold the steeringwheel firmly and slowly move to a safeplace on the side of the road.
Have a flat serviced by an authorizeddealer to prevent damage to the systemsensors. See Tire Pressure MonitoringSystem Precautions (page 502).Replacethe spare tire with a road tire as soon aspossible. During repairing or replacing theflat tire, have the authorized dealer inspectthe system sensor for damage.
Note:The use of tire sealant may damageyour tire pressure monitoring system andshould only be used in roadsideemergencies.
Note:The tire pressure monitoring systemindicator light illuminates when the sparetire is in use. To restore the full function ofthe monitoring system, all road wheelsequipped with tire pressure monitoringsensors must be mounted on this vehicle.
Dissimilar Spare Wheel and TireAssembly Information
WARNING: Failure to follow theseguidelines could result in an increasedrisk of loss of vehicle control, injury ordeath.
If you have a dissimilar spare wheel andtire, then it is intended for temporary useonly. This means that if you need to use it,you should replace it as soon as possiblewith a road wheel and tire assembly thatis the same size and type as the road tiresand wheels that were originally providedby Ford. If the dissimilar spare tire or wheelis damaged, it should be replaced ratherthan repaired.
A dissimilar spare wheel and tire assemblyis defined as a spare wheel and tireassembly that is different in brand, size orappearance from the road tires andwheels.
Full-size dissimilar spare
When driving with the full-size dissimilarspare wheel and tire assembly, do not:
•Exceed 70 mph (113 km/h).
•Use more than one dissimilar sparewheel and tire assembly at a time.
•Use snow chains on the end of thevehicle with the dissimilar spare wheeland tire assembly.
•Engage any four-wheel drive mode.See Four-Wheel Drive Limitations(page 239).
When driving with the full-size dissimilarspare wheel and tire assembly, 4WDfunctionality may be limited. You mayexperience the following:
•Additional noise from the transfer caseor other drive components.
•Difficulty shifting out of a mechanicallylocked 4WD mode.
When driving with the full-size dissimilarspare wheel and tire assembly, it isrecommended that you do not:
•Engage 4WD High or 4WD Low, ifequipped, other than to get your vehicleunstuck. .
The usage of a full-size dissimilar sparewheel and tire assembly can lead toimpairment of the following:
•Handling, stability and brakingperformance.
•Comfort and noise.
•Ground clearance and parking at curbs.
•Winter weather driving capability.
•Wet weather driving capability.
•Four-wheel drive capability.
