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.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; instead,
disengage overdrive or manually
shift to a lower gear. When
descending a steep hill, avoid
sudden hard braking as you could
lose control. When you brake hard,
the front wheels can’t turn and if
they aren’t turning, you won’t be able to steer. The front wheels have to
be turning in order to steer the vehicle.
If your vehicle has anti-lock brakes, apply the brakes steadily. Do not
pump the brakes.
Driving on snow and ice
WARNING: If you are driving in slippery conditions that require
tire chains or cables, then it is critical that you drive cautiously.
Keep speeds down, allow for longer stopping distances and avoid
aggressive steering to reduce the chances of a loss of vehicle control
which can lead to serious injury or death. If the rear end of the vehicle
slides while cornering, steer in the direction of the slide until you
regain control of the vehicle.
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 and consider using one of the lower
gears. In emergency stopping situations, 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
(ABS).
Maintenance and modifications
The suspension and steering systems on your vehicle have been designed
and tested to provide predictable performance whether loaded or empty
and durable load carrying capability. For this reason, Ford Motor
Company strongly recommends that you do not make modifications such
as adding or removing parts (such as lift kits or stabilizer bars) or by
using replacement parts not equivalent to the original factory equipment.
Any modifications to a vehicle that raise the center of gravity can make
it more likely the vehicle will roll over as a result of a loss of control.
Ford Motor Company recommends that caution be used with any vehicle
equipped with a high load or device (such as ladder racks or pickup box
cover).
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 components is recommended if the vehicle is subjected to
heavy off-road usage.

Note:Certain states require electric trailer brakes for trailers over a
specified weight. Be sure to check state regulations for this specified
weight. The maximum trailer weights listed may be limited to this
specified weight, as your vehicle’s electrical system may not include the
wiring connector needed to use electric trailer brakes.
Your vehicle may tow a trailer provided the maximum trailer weight is
less than or equal to the maximum trailer weight listed for your vehicle
configuration on the following chart.
To calculate the maximum loaded trailer weight for your vehicle:
1. Start with the gross combined weight rating for your vehicle model and axle ratio. See the following chart.
2. Subtract all of the following that apply to your vehicle: •Vehicle curb weight
• Hitch hardware weight, such as a draw bar, ball, locks or weight
distributing
• Driver weight
• Passenger(s) weight
• Payload, cargo and luggage weight
• Aftermarket equipment weight.
3. This equals the maximum loaded trailer weight for this combination.
Note: The trailer tongue load figures into the payload for your vehicle.
Reduce the total payload by the final trailer tongue weight.
Consult an authorized dealer to determine the maximum trailer weight
allowed for your vehicle if you are not sure.

TRANSPORTING THE VEHICLE
If you need to have your vehicle towed, contact a professional towing
service or, if you are a member of a roadside assistance program, your
roadside assistance service provider.
We recommend the use of a wheel lift and dollies or flatbed equipment
to tow your vehicle. Do not tow with a slingbelt. Ford Motor Company
has not approved a slingbelt towing procedure. Vehicle damage may
occur if towed incorrectly, or by any other means.
Ford Motor Company produces a towing manual for all authorized tow
truck operators. Have your tow truck operator refer to this manual for
proper hook-up and towing procedures for your vehicle.
It is acceptable to have your two-wheel drive vehicle towed with the
front wheels on the ground (without dollies) and the rear wheels off the
ground.
We recommend towing a four-wheel drive vehicle with all wheels off the
ground, such as using a wheel lift and dollies or flatbed equipment.

GENERAL INFORMATION
Notice to Utility Vehicle, Van and Truck Owners
WARNING:Utility vehicles have a significantly higher rollover
rate than other types of vehicles. To reduce the risk of serious
injury or death from a rollover or other crash you must:
• Avoid sharp turns and abrupt maneuvers.
• Drive at safe speeds for the conditions.
• Keep tires properly inflated.
• Never overload or improperly load your vehicle.
• Make sure every passenger is properly restrained.
WARNING: In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing a seat belt.
All occupants must wear seat belts. Children and infants must use
appropriate restraints to minimize the risk of injury or ejection.
Utility vehicles, vans and trucks handle
differently than passenger cars in the
various driving conditions that are
encountered on streets, highways and
off-road. Utility vehicles, vans 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.
Four-Wheel Drive System (If Equipped)
WARNING: Do not become overconfident in the ability of
four-wheel drive vehicles. Although a four-wheel drive vehicle
may accelerate better than a two-wheel drive vehicle in low-traction
situations, it will not stop any faster than two-wheel drive vehicles.
Always drive at a safe speed.
A vehicle equipped with four-wheel drive (when selected) has the ability
to use all four wheels to power itself. This increases traction which may
enable you to safely drive over terrain and road conditions that a
conventional two-wheel drive vehicle cannot.

Power is supplied to all four wheels through a transfer case or power
transfer unit. Four-wheel drive vehicles allow you to select different drive
modes as necessary. You can find information on transfer case operation
and shifting procedures in theTransmissionchapter. You can find
information on transfer case maintenance in the Maintenancechapter.
You should become thoroughly familiar with this information before you
operate your vehicle.
On some four-wheel drive models, the initial shift from two-wheel drive
to four-wheel drive while the vehicle is moving can cause a momentary
clunk and ratcheting sound. These sounds are normal as the front
drivetrain comes up to speed and are not cause for concern.
How Your Vehicle Differs from Other Vehicles
Sport-utility vehicles, vans and
trucks can differ from some other
vehicles in a few noticeable ways.
Your vehicle may be:
•Higher – to allow higher load
carrying capacity and to allow it
to travel over rough terrain
without getting hung up or
damaging underbody
components.
• Shorter – 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.

G.H: Indicates the tire’s speed rating. The speed rating denotes the
speed at which a tire is designed to be driven for extended periods of
time under a standard condition of load and inflation pressure. The tires
on your vehicle may operate at different conditions for load and inflation
pressure. These speed ratings may need to be adjusted for the difference
in conditions. The ratings range from 81 mph (130 km/h) to 186 mph
(299 km/h). These ratings are listed in the following chart.
Note: You may not find this information on all tires because it is not
required by federal law.
Letter rating Speed rating - mph (km/h)
M 81 (130)
N 87 (140)
Q 99 (159)
R 106 (171)
S 112 (180)
T 118 (190)
U 124 (200)
H 130 (210)
V 149 (240)
W 168 (270)
Y 186 (299 )
Note: For tires with a maximum speed capability over 149 mph
(240 km/h), tire manufacturers sometimes use the letters ZR. For
those with a maximum speed capability over 186 mph (299 km/h), tire
manufacturers always use the letters ZR.
H. U.S. DOT Tire Identification Number (TIN): This begins with the
letters DOT and indicates that the tire meets all federal standards. The
next two numbers or letters are the plant code designating where it was
manufactured, the next two are the tire size code and the last four
numbers represent the week and year the tire was built. For example,
the numbers 317 mean the 31st week of 1997. After 2000 the numbers
go to four digits. For example, 2501 means the 25th week of 2001. The
numbers in between are identification codes used for traceability. This
information is used to contact customers if a tire defect requires a recall.

Safety Practices
WARNING:If your vehicle is stuck in snow, mud, or sand, do
not rapidly spin the tires. Spinning the tires can tear the tire and
cause an explosion. A tire can explode in as little as three to five
seconds.
WARNING: Do not spin the wheels at over 35 mph (56 km/h).
The tires may fail and injure a passenger or bystander.
Driving habits have a great deal to do with your tire mileage and safety.
• Observe posted speed limits.
• Avoid fast starts, stops and turns.
• Avoid potholes and objects on the road.
• Do not run over curbs or hit the tire against a curb when parking.
Highway Hazards
No matter how carefully you drive, there is always the possibility that
you may eventually have a flat tire on the highway. Drive slowly to the
closest safe area out of traffic. This may further damage the flat tire, but
your safety is more important.
If you feel a sudden vibration or ride disturbance while driving, or you
suspect your tire or vehicle has been damaged, immediately reduce your
speed. Drive with caution until you can safely pull off the road. Stop and
inspect the tires for damage. If a tire is under-inflated or damaged,
deflate it, remove the wheel and replace it with your spare tire and
wheel. If you cannot detect a cause, have the vehicle towed to the
nearest repair facility or tire dealer to have the vehicle inspected.
Tire and Wheel Alignment
A bad jolt from hitting a curb or pothole can cause the front end of your
vehicle to become misaligned or cause damage to your tires. If your
vehicle seems to pull to one side when you are driving, the wheels may
be out of alignment. Have an authorized dealer check the wheel
alignment periodically.
Wheel misalignment in the front or the rear can cause uneven and rapid
treadwear of your tires and should be corrected by an authorized dealer.
Front-wheel drive vehicles and those with an independent rear
suspension may require alignment of all four wheels.
