How your vehicle differs from other vehicles
SUV and trucks can differ from
some other vehicles in a few
noticeable ways. Your vehicle may
be:
²Higher ± to allow higher load
carrying capacity and to allow it
to travel over rough terrain
without getting hung up or
damaging underbody components.
²Shorter ± to give it the capability
to approach inclines and drive
over the crest of a hill without
getting hung up or damaging
underbody components. All other
things held equal, a shorter
wheelbase may make your vehicle quicker to respond to steering
inputs than a vehicle with a longer wheelbase.
²Narrower Ð to provide greater
maneuverability in tight spaces,
particularly in off-road use.
As a result of the above dimensional
differences, SUV's and trucks often
will have a higher center of gravity
and a greater difference in center of
gravity between the loaded and
unloaded condition.
These differences that make your
vehicle so versatile also make it
handle differently than an ordinary
passenger car.
Vehicle Characteristics

DRIVING ON ROADWAYS
Vehicles with a higher center of gravity such as utility vehicles
and trucks handle differently than vehicles with a lower center
of gravity. Utility vehicles and trucks 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, excessive speed or 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.
Basic operating principles
²Drive slower in strong crosswinds which can affect the normal steering
characteristics of your vehicle.
²Be extremely careful when driving on pavement made slippery by
loose sand, water, gravel, snow or ice.
²Do not use 4WD on dry, hard surfaced roads (except models equipped
with Auto 4WD or AWD). This may damage the drivelines and axles.
If your vehicle goes off the edge of the pavement
²If your vehicle goes off the edge
of the pavement, slow down and
avoid severe brake application or
aggressive steering. 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.
²If you have the space, 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.
²It often may be less risky to strike small inanimate objects, (such as
highway reflectors), and incur 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 rollover. Remember, your
safety and the safety of others should be your primary concern.

Emergency maneuvers
²In an emergency situation where a sudden sharp turn must be made,
remember to avoid ªover-drivingº your vehicle, i.e., turn the steering
wheel only as rapidly and as far as required to avoid the emergency.
Avoid abrupt steering, acceleration or braking which could increase
the risk of loss of vehicle control or vehicle rollover. Instead, smooth
variations of the accelerator and/or brake pedal pressure should be
utilized if changes in vehicle speed are called for. Use all available road
surface to return the vehicle to a safe direction of travel.
²In the event of an emergency stop, avoid skidding the tires and do not
attempt any sharp steering wheel movements.
²If the vehicle goes from one type of road surface to another (i.e., from
concrete to gravel), there will be a change in the way the vehicle
responds in steering, acceleration or braking. Again, avoid abrupt
inputs steering or braking inputs.
Snow and ice
Your 4WD or AWD vehicle will have advantages over two-wheel drive
vehicles in snow and on ice by providing increased driving traction.
However, if you suddenly change speed or direction, you may lose
traction and in turn, control as is the case with all vehicles. 4WD and
AWD vehicles can slide on slippery roads just like any other vehicle.
Should the rear end of the vehicle start to slide while cornering on
snowy or icy roads, turn the steering wheel in the direction of the slide
until you regain control. Avoid sudden braking as well. Although a 4WD
or AWD vehicle may accelerate better than a two-wheel drive vehicle in
snow and ice, it won't stop any faster, because as in two-wheel drive
vehicles, braking occurs at all four wheels. Do not become overconfident
in the ability of 4WD and AWD vehicles to compensate for aggressive
driving maneuvers in poor road conditions.
Make sure you allow sufficient distance between you and other vehicles
for stopping. In emergency stopping situations, avoid locking the wheels.
²For vehicles without anti-lock brakes, use a ªsqueezeº technique: push
on the brake pedal with a steadily increasing force which allows the
wheels to brake yet continue to roll so that you may steer in the
direction you want to travel. If you lock the wheels, release the brake
pedal and repeat the squeeze technique.

DRIVING OFF-ROAD
ªTread Lightlyº is an educational
program designed to increase
public awareness of land-use
regulations and responsibilities in
our nations wilderness areas.
Ford 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 ªtreading lightlyº.
Driving off-road requires good judgment to avoid personal injury and
vehicle damage from concealed objects such as rocks and stumps. Know
the terrain or examine maps of the area before driving off road. 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. To avoid loss of control,
maintain a firm grip on the steering wheel, especially in rough terrain.
Sudden changes in terrain can result in abrupt steering wheel
motion. To maintain better control and avoid injury to your hand
or wrist, grip the steering wheel from the outside. Do not grip the
spokes.
Driving on sand
When driving over sand, try to keep all four wheels on the most solid
area of the trail. Avoid reducing the tire pressure. Instead, shift to a
lower gear and drive steadily through the terrain. Apply the accelerator
slowly and avoid spinning the wheels.
Avoid reducing tire pressure. Operating your vehicle with below
the recommended tire pressure can increase the risk of loss of
vehicle control, vehicle rollover, personal injury and death. If you
choose to reduce the tire pressure for off-road operation, make sure
you re-inflate the tires as soon as possible.
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.

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.
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.
If you do stall out, do not try to
turn around because you might
induce a rollover. It is better to back
down to a safe location.
Apply just enough power to the
wheels to climb the hill. Too much
power can cause the tires to slip,
spin or lose traction, resulting in
loss of vehicle control.
Descend a hill in the same gear you
would use to climb up the hill to
avoid excessive brake application
and brake overheating. Do not
descend in neutral. Disengage
overdrive or manually shift to a
lower gear. When descending a
steep hill, avoid sudden hard
braking as you could lose control. In
a vehicle without four wheel
anti-lock brakes, if you lock up the
front brakes, the front wheels can't
roll and if they aren't rolling, you won't be able to steer. The front wheels
have to be rolling in order to steer the vehicle. Rapid pumping of the
brake pedal will help you slow the vehicle and still maintain steering
control. If your vehicle has four wheel anti-lock brakes, apply and hold
the brakes firmly. Do not ªpumpº the brakes.

3. Add air to reach the Ford recommended air pressure.
Note:If you overfill the tire, release air by pushing on the metal stem in
the center of the valve. Then recheck the pressure with your tire gauge.
4. Replace the valve cap.
5. Repeat this procedure for each tire, including the spare.
Note:Some spare tires require higher inflation pressure than the other tires.
6. Visually inspect the tires to make sure there are no nails or other objects
embedded that could poke a hole in the tire and cause an air leak.
7. Check the sidewalls to make sure there are no gouges, cuts, bulges or
other irregularities.
TIRE REPLACEMENT REQUIREMENTS
Your vehicle is equipped with tires designed to provide safe ride and
handling capability.
Only use replacement tires and wheels that are the same size
and type (such as P-metric versus LT-metric or all-season versus
all-terrain) as those originally provided by Ford. Use of any tire or
wheel not recommended by Ford can affect the safety and
performance of your vehicle, which could result in an increased risk of
loss of vehicle control, vehicle rollover, personal injury and death.
Additionally the use of non-recommended tires and wheels could cause
steering, suspension, axle or transfer case/power transfer unit failure.
See your Owner Guide for additional information. If you have questions
regarding tire replacement, see an authorized Ford or Lincoln/Mercury
dealer.
Make sure all tires and wheels on the vehicle are of the same size, type,
tread design, brand, load-carrying capacity and speed rating because it
can affect the safety and performance of your vehicle, which could result
in an increased risk of loss of vehicle control, vehicle rollover, personal
injury and death.

LOADING YOUR VEHICLE
Passenger and cargo load limits
The combined weight of all occupants and all cargo (including added
accessories) must not exceed themaximum payloadfor your vehicle.
The maximum payload for your vehicle can be found on the tire label on
the driver's door or door pillar. Look for statement ªTHE COMBINED
WEIGHT OF OCCUPANTS AND CARGO SHOULD NEVER EXCEED XXX
KG OR XXX LBSº to determine your vehicle's maximum payload.
The appropriate loading capacity of your vehicle can be limited
either by volume capacity (how much space is available) or by
payload capacity (how much weight the vehicle should carry). Once
you have reached the maximum payload of your vehicle, do not add
more cargo, even if there is space available. Overloading or improperly
loading your vehicle can contribute to loss of vehicle control and
vehicle rollover.
In addition tomaximum payload, additional loading terms and weight
ratings are very important, particularly when towing a trailer or when a
heavy accessory such as a snowplow has been added to the vehicle.
Other terms related to loading includebase curb weight, gross vehicle
weight rating(GVWR),gross axle weight rating(GAWR),gross
combined weight rating(GCWR). Refer to your ªOwner's Guideº for
additional information regarding these terms and maximum safe weight
limits.
Effects of improperly loading or overloading your vehicle
Improper weight distribution and exceeding the maximum payload can
have serious consequences in terms of passenger safety, including
damage to the suspension system, springs, and shock absorbers, reduced
braking capability, handling or steering problems, irregular tire wear, tire
failure or other damage.
Loaded vehicles, with a higher center of gravity, may handle
differently than unloaded vehicles. Do not overload your vehicle
and use extra precautions, such as driving at slower speeds, avoiding
abrupt steering changes and allowing for increased stopping distance,
when driving a heavily loaded vehicle. Over loading or loading the
vehicle improperly can deteriorate handling capability and contribute
to loss of vehicle control and vehicle rollover.

MAINTENANCE AND MODIFICATIONS
The suspension and steering systems on your vehicle have been carefully
designed to provide safe, predictable performance and durable load
carrying capability. Do not make modifications such as adding or
removing parts (such as lift kits or stabilizer bars) or using replacement
parts not equivalent to the original factory equipment because these
modifications can affect the safety of your vehicle.
Do not use ªaftermarket lift kitsº or other suspension
modifications. ªAftermarket lift kitsº could adversely affect the
vehicle's handling characteristics, which could result in an increased
risk of loss of vehicle control, vehicle rollover, personal injury and
death.
Any modifications to a vehicle that raise the center of gravity can make
it easier to induce vehicle rollover. Ford recommends that you take extra
precautions, such as driving at lower speeds, avoiding abrupt steering
changes and allowing for increased stopping distance, for any vehicle
equipped with a high load (for example, roof racks).
Failure to maintain your vehicle properly may void the warranty, increase
your repair cost, reduce vehicle performance and operational capabilities
and adversely affect driver and passenger safety. Frequent inspection of
vehicle chassis and powertrain components is recommended if the
vehicle is subjected to heavy off-road usage. Refer to the ªOwner's
Guideº and ªService Guideº for proper maintenance instructions and
schedules.
