vehicle is moving at speeds less than 3 mph (5 km/h). The system is not
effective at speeds above 3 mph (5 km/h) and may not detect certain
angular or moving objects.
To help avoid personal injury, please read and understand the
limitations of the reverse sensing system as contained in this
section. Reverse sensing is only an aid for some (generally large and
fixed) objects when moving in reverse on a flat surface at “parking
speeds”. Inclement weather may also affect the function of the RSS;
this may include reduced performance or a false activation.
To help avoid personal injury, always use caution when in
reverse and when using the RSS.
This system is not designed to prevent contact with small or
moving objects. The system is designed to provide a warning to
assist the driver in detecting large stationary objects to avoid damaging
the vehicle. The system may not detect smaller objects, particularly
those close to the ground.
Certain add-on devices such as large trailer hitches, bike or
surfboard racks and any device that may block the normal
detection zone of the RSS system may create false beeps.

The RSS detects obstacles up to 6
feet (1.8 meters) from the rear
bumper with a decreased coverage
area at the outer corners of the
bumper, (refer to the figures for
approximate zone coverage areas).
As you move closer to the obstacle,
the rate of the tone increases. When
the obstacle is less than 10 inches
(25.0 cm) away, the tone will sound
continuously. If the RSS detects a
stationary or receding object further
than 10 inches (25.0 cm) from the
side of the vehicle, the tone will
sound for only three seconds. Once
the system detects an object
approaching, the tone will sound
again.
The RSS automatically turns on
when the gear selector is placed in
R (Reverse) and the ignition is on.
An RSS control allows the driver to
turn the RSS on and off. To turn the RSS off, the ignition must be on.
The system will remain off until either the RSS control is pressed again
or the ignition is turned off, then on again. An indicator light on the
control will illuminate when the system is turned off. If the indicator
light illuminates when the RSS is not turned off, it may indicate a failure
in the RSS.
Keep the RSS sensors (located on the rear bumper/fascia) free
from snow, ice and large accumulations of dirt (do not clean the
sensors with sharp objects). If the sensors are covered, it will
affect the accuracy of the RSS.
If your vehicle sustains damage to the rear bumper/fascia, leaving
it misaligned or bent, the sensing zone may be altered causing
inaccurate measurement of obstacles or false alarms.

FOUR WHEEL DRIVE (4WD) SYSTEM
For important information regarding safe operation of this type
of vehicle, seePreparing to drive your vehiclein this chapter.
Your vehicle is equipped with an intelligent 4WD System that
continuously monitors vehicle conditions and automatically adjusts the
power distribution between the front and rear wheels. It combines
transparent all-surface operation with highly capable four-wheel drive.
The 4WD system is always active and requires no driver input. It is
capable of handling all road conditions, including street and highway
driving as well as off-road and winter driving.
During very extreme off-road events, the 4WD system has a heat
protection mode to protect itself from damage. If the system detects an
overheat condition, it will enter a locked mode. If the heat in the 4WD
system continues to rise in locked mode, it will disable itself. To exit heat
protection mode, simply stop the vehicle and allow it to cool for five
minutes with the key in the 3 (RUN) position.

Driving off-road with truck and utility vehicles
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.
How your vehicle differs from other vehicles
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.
Basic operating principles
•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, and 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.
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 arenot
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, 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.

If your vehicle gets stuck
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.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
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.
Always set the parking brake fully and make sure the gearshift is
latched in P (Park). Turn the ignition to the LOCK position and
remove the key whenever you leave your vehicle.
If the parking brake is fully released, but the brake warning lamp
remains illuminated, the brakes may not be working properly.
See your authorized dealer.
Do not spin the wheels at over 35 mph (56 km/h). The tires may
fail and injure a passenger or bystander.
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
required. 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.

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 arenot
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, 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.
•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 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
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.
Driving through deep water may damage the transmission.
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 nation’s
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
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.Avoid driving crosswise or turning on steep
slopes or hills. 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.
If you do stall out, do not try to
turn around because you might roll
over. It is better to back down to a
safe location.
Apply just enough power to the
wheels to climb the hill. Too much
power will cause the tires to slip,
spin or lose traction, resulting in
loss of vehicle control.

Do not descend a hill in N (Neutral)
and avoid sudden hard braking as
you could lose control.
Since your vehicle has anti-lock brakes, apply the brakes steadily. Do not
“pump” the brakes.
Driving on snow and ice
4WD vehicles have advantages over 2WD vehicles in snow and ice but
can skid like any other vehicle.
Should you start to slide while driving on snowy or icy roads, turn the
steering wheel in the direction of the slide until you regain control.
Avoid sudden applications of power and quick changes of direction on
snow and ice. Apply the accelerator slowly and steadily when starting
from a full stop.
Avoid sudden braking as well. Although a 4WD vehicle may accelerate
better than a two-wheel drive vehicle in snow and ice, it won’t stop any
faster, because as in other vehicles, braking occurs at all four wheels. Do
not become overconfident as to road conditions.
Make sure you allow sufficient distance between you and other vehicles
for stopping; drive slower than usual. Since your vehicle is equipped with
a Four Wheel Anti-Lock Brake System (ABS), apply the brake steadily.
Do not “pump” the brakes. Refer to theBrakessection of this chapter
for additional information on the operation of the anti-lock brake system.
4WD vehicles should be driven with traction devices as referred to in
Using snow tires and traction devicesin theTires, Wheels and
Loadingchapter.
Maintenance and Modifications
The suspension and steering systems on your vehicle have been designed
and tested to provide durable load carrying capability and predictable
