USING FOUR-WHEEL DRIVE (4WD) (if equipped)
WARNING:For important information regarding safe operation
of this type of vehicle, see General Informationin theWheels
and Tires chapter.
Note: Do not use 4X4 mode on dry, hard surfaced roads. Doing so will
produce excessive noise, increase tire wear and may damage drive
components. 4X4 mode is only intended for consistently slippery or loose
surfaces.
Your 4x4 features the heavy-duty Control Trac® 4WD system which
includes a computer-operated transfer case. This unique system is
interactive with the road, continually monitoring and adjusting torque
delivery to the front and rear wheels to optimize vehicle control.
4WD Indicator Lights
The indicator lights illuminate in the message center in the
reconfigurable telltale (RTT) location under the following conditions.
Refer to Warning Lamps and Indicators in theInstrument Cluster
chapter.
Note: When a 4X4 system fault is present, the system will typically
remain in whichever 4X4 mode was selected prior to the fault condition
occurring. It will not default to 4X2 in all circumstances. When this
warning is displayed, have your vehicle serviced by an authorized dealer.
4X2- Momentarily illuminates when 2H is selected.
4X4 AUTO - Continuously illuminates when 4A is selected
4X4 - Continuously illuminates when 4H is selected.

4WD switch positions
WARNING:Utility and four-wheel drive vehicles are not
designed for cornering at speeds as high as passenger cars any
more than low-slung sports cars are designed to perform satisfactorily
under off-road conditions. Avoid sharp turns or abrupt maneuvers in
these vehicles.
Note: The AdvanceTrac® with RSC® stability enhancement system can
be turned off manually by pressing the AdvanceTrac button, see the
Traction Control chapter for more information. This will disable the
engine management feature, allowing the vehicle to maintain full power
and enhanced momentum through the obstacle.
Note: The Control Trac selector switch should not be changed while the
rear wheels are slipping.
The Control Trac system functions in
four modes:
•2H (4X2) delivers power to the
rear wheels only. The message
center will momentarily display 4x2
when this mode is selected. This mode is appropriate for normal
on-road driving on dry pavement and provides the best fuel economy.
• 4A (4X4 AUTO) provides electronic control four-wheel drive with
power delivered to all four wheels, as required, for increased traction.
The message center will display 4A when this mode is selected. This
mode is appropriate for all on-road driving conditions, such as dry
road surfaces, wet pavement, snow, or gravel.
• 4H (4X4) provides electronically locked four-wheel drive power to
front and rear wheels. The message center will display 4X4 when this
mode is selected. This mode is not recommended for use on dry
pavement. This mode is only intended for severe winter or off-road
conditions, such as deep snow, ice or shallow sand.
Shifting between system modes
Note: Do not perform these operations if the rear wheels are slipping.
Note: Some noise may be heard as the system shifts or engages.
Press any button (4X2, 4X4 AUTO or 4X4) at a stop or while driving.
The message center may display a message indicating a 4X4 shift is in
progress. Once the shift is complete the message center will then display
the system mode selected.

How Your Vehicle Differs From Other Vehicles
WARNING:Vehicles with a higher center of gravity such as
utility and four-wheel drive vehicles handle differently than
vehicles with a lower center of gravity. Utility and four-wheel drive
vehicles are notdesigned for cornering at speeds as high as passenger
cars any more than low-slung sports cars are designed to perform
satisfactorily under off-road conditions. Avoid sharp turns, excessive
speed and abrupt maneuvers in these vehicles. Failure to drive
cautiously could result in an increased risk of loss of vehicle control,
vehicle rollover, personal injury and death.
Truck and utility vehicles can differ from some other vehicles. Your
vehicle may be higher to allow it to travel over rough terrain without
getting hung up or damaging underbody components.
The differences that make your vehicle so versatile also make it handle
differently than an ordinary passenger car.
Maintain steering wheel control at all times, especially in rough terrain.
Since sudden changes in terrain can result in abrupt steering wheel
motion, make sure you grip the steering wheel from the outside. Do not
grip the spokes.
Drive cautiously to avoid vehicle damage from concealed objects such as
rocks and stumps.
You should either know the terrain or examine maps of the area before
driving. Map out your route before driving in the area. To maintain
steering and braking control of your vehicle, you must have all four
wheels on the ground and they must be rolling, not sliding or spinning.
Driving Off-Road With Truck and Utility Vehicles
Note: On some 4WD models, the initial shift from two-wheel drive to
four-wheel drive while the vehicle is moving can cause some momentary
clunk and ratcheting sounds. This is the front drivetrain coming up to
speed and the automatic locking hubs engaging and is not cause for
concern.
Note: Your vehicle may be equipped with a front air dam that can
become damaged (due to reduced ground clearance) when taking your
vehicle off-road. This air dam can be taken off by removing two bolts.
4WD vehicles are specially equipped for driving on sand, snow, mud and
rough terrain and have operating characteristics that are somewhat
different from conventional vehicles, both on and off the road.

Power is supplied to all four wheels through a transfer case. On 4WD
vehicles, the transfer case allows you to select between different 4WD
modes when necessary. Information on transfer case operation and
shifting procedures can be found in this chapter. Information on transfer
case maintenance can be found in theMaintenancechapter. You should
become thoroughly familiar with this information before you operate
your vehicle.
4WD (when you select a 4WD mode) uses all four wheels to power the
vehicle. This increases traction, enabling you to drive over terrain and
road conditions that a conventional two-wheel drive vehicle cannot.
Basic Operating Principles In Special Conditions
• Do not use 4x4 on dry, hard surfaced roads. Doing so will produce
excessive noise, increase tire wear and may damage drive components.
4WD modes are only intended for consistently slippery or loose
surfaces.
• Drive slower in strong crosswinds which can affect the normal steering
characteristics of your vehicle.
• Be extremely careful when driving on pavement made slippery by
loose sand, water, gravel, snow or ice.
If your vehicle goes off the edge of the pavement
• If your vehicle goes off the edge of the pavement, slow down, but
avoid severe brake application, ease the vehicle back onto the
pavement only after reducing your speed. Do not turn the steering
wheel too sharply while returning to the road surface.
• It may be safer to stay on the apron or shoulder of the road and slow
down gradually before returning to the pavement. You may lose
control if you do not slow down or if you turn the steering wheel too
sharply or abruptly.
• It often may be less risky to strike small objects, such as highway
reflectors, with minor damage to your vehicle rather than attempt a
sudden return to the pavement which could cause the vehicle to slide
sideways out of control or roll over. Remember, your safety and the
safety of others should be your primary concern.
If your vehicle gets stuck
WARNING: Do not spin the wheels at over 35 mph (56 km/h).
The tires may fail and injure a passenger or bystander.

Note:Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Note: Do not rock the vehicle for more than a few minutes or damage to
the transmission and tires may occur or the engine may overheat.
If your vehicle gets stuck in mud or snow it may be rocked out by
shifting between forward and reverse gears, stopping between shifts, in a
steady pattern. Press lightly on the accelerator in each gear.
Emergency maneuvers
• In an unavoidable emergency situation where a sudden sharp turn
must be made, remember to avoid over-driving your vehicle, i.e., turn
the steering wheel only as rapidly and as far as required to avoid the
emergency. Excessive steering will result in less vehicle control, not
more. Additionally, smooth variations of the accelerator and/or brake
pedal pressure should be utilized if changes in vehicle speed are called
for. Avoid abrupt steering, acceleration or braking which could result
in an increased risk of loss of vehicle control, vehicle rollover and/or
personal injury. Use all available road surface to return the vehicle to a
safe direction of travel.
• In the event of an emergency stop, avoid skidding the tires and do not
attempt any sharp steering wheel movements.
• If the vehicle goes from one type of surface to another (i.e., from
concrete to gravel) there will be a change in the way the vehicle
responds to a maneuver (steering, acceleration or braking). Again,
avoid these abrupt inputs.
Sand
When driving over sand, try to keep all four wheels on the most solid
area of the trail. Avoid reducing the tire pressures but shift to a lower
gear and drive steadily through the terrain. Apply the accelerator slowly
and avoid spinning the wheels.
Avoid excessive speed because vehicle momentum can work against you
and cause the vehicle to become stuck to the point that assistance may
be required from another vehicle. Remember, you may be able to back
out the way you came if you proceed with caution.
Mud and water
Note: Driving through deep water may damage the vehicle.
If you must drive through high water, drive slowly. Traction or brake
capability may be limited.

When driving through water, determine the depth; avoid water higher
than the bottom of the hubs (if possible) and proceed slowly. If the
ignition system gets wet, the vehicle may stall.
Once through water, always try the brakes. Wet brakes do not stop the
vehicle as effectively as dry brakes. Drying can be improved by moving
your vehicle slowly while applying light pressure on the brake pedal.
Be cautious of sudden changes in vehicle speed or direction when you
are driving in mud. Even 4WD vehicles can lose traction in slick mud. As
when you are driving over sand, apply the accelerator slowly and avoid
spinning your wheels. If the vehicle does slide, steer in the direction of
the slide until you regain control of the vehicle.
If the transmission, transfer case or front axle are submerged in water,
their fluids should be checked and changed, if necessary.
If the front or rear axle is submerged in water, the axle lubricant should
be replaced.
After driving through mud, clean off residue stuck to rotating driveshafts
and tires. Excess mud stuck on tires and rotating driveshafts causes an
imbalance that could damage drive components.“Tread Lightly” is an educational
program designed to increase public
awareness of land-use regulations
and responsibilities in our nations
wilderness areas. Ford Motor
Company joins the U.S. Forest
Service and the Bureau of Land Management in encouraging you to help
preserve our national forest and other public and private lands by
“treading lightly.”
Driving on hilly or sloping terrain
Note: Avoid driving crosswise or turning on steep slopes or hills.
Although natural obstacles may make it necessary to travel diagonally up
or down a hill or steep incline, you should always try to drive straight up
or straight down. . A danger lies in losing traction, slipping sideways and
possibly rolling over. Whenever driving on a hill, determine beforehand
the route you will use. Do not drive over the crest of a hill without
seeing what conditions are on the other side. Do not drive in reverse
over a hill without the aid of an observer.
When climbing a steep slope or hill, start in a lower gear rather than
downshifting to a lower gear from a higher gear once the ascent has
started. This reduces strain on the engine and the possibility of stalling.
