NOTICE TO UTILITY VEHICLE AND TRUCK OWNERS
Utility vehicles and trucks handle
differently than passenger cars in
the various driving conditions that
are encountered on streets,
highways and off-road. 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.
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; and
• 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 and children/infants must use
appropriate restraints to minimize the risk of injury or ejection.
Study your owner’s guide and any supplements for specific information
about equipment features, instructions for safe driving and additional
precautions to reduce the risk of an accident or serious injury.
VEHICLE CHARACTERISTICS
4WD and AWD Systems (if equipped)
A vehicle equipped with AWD or 4WD (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. Tires, Wheels and Loading

Owners Guide, 2nd Printing
USA (fus)

Power is supplied to all four wheels through a transfer case or power
transfer unit. 4WD vehicles allow you to select different drive modes as
necessary. Information on transfer case operation and shifting procedures
can be found in the Driving chapter. Information on transfer case
maintenance can be found in the Maintenance and Specifications
chapter. You should become thoroughly familiar with this information
before you operate your vehicle.
On some 4WD models, the initial shift from two-wheel drive to 4WD
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 is not cause for concern.
WARNING: Do not become overconfident in the ability of 4WD
and AWD vehicles. Although a 4WD or AWD vehicle may
accelerate better than two-wheel drive vehicle in low traction
situations, it won’t stop any faster than two-wheel drive vehicles.
Always drive at a safe speed.
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:
• 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.Tires, Wheels and Loading

U.S. DOT Tire Identification Number (TIN)
Both U.S. and Canada Federal regulations require tire manufacturers to
place standardized information on the sidewall of all tires. This
information identifies and describes the fundamental characteristics of
the tire and also provides a U.S. DOT Tire Identification Number for
safety standard certification and in case of a recall.
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.
Tire Replacement Requirements
Your vehicle is equipped with tires designed to provide a safe ride and
handling capability.
WARNING: Only use replacement tires and wheels that are the
same size, load index, speed rating and type (such as P-metric
versus LT-metric or all-season versus all-terrain) as those originally
provided by Ford. The recommended tire and wheel size may be found
on either the Safety Compliance Certification Label or the Tire Label
which is located on the B-Pillar or edge of the driver’s door. If this
information is not found on these labels then you should contact your
authorized dealer as soon as possible. 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. If you
have questions regarding tire replacement, contact your authorized
dealer as soon as possible. Tires, Wheels and Loading

• Do not run over curbs or hit the tire against a curb when parking
WARNING: If your vehicle is stuck in snow, mud, sand, etc., 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.
Highway hazards
No matter how carefully you drive there’s 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 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’re 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 (FWD) vehicles and those with an independent rear
suspension (if equipped) may require alignment of all four wheels.
The tires should also be balanced periodically. An unbalanced tire and
wheel assembly may result in irregular tire wear.
Tire rotation
Rotating your tires at the recommended interval (as indicated in the
scheduled maintenance information that comes with your vehicle) will
help your tires wear more evenly, providing better tire performance and
longer tire life. Tires, Wheels and Loading

Sometimes irregular tire wear can be corrected by rotating the tires.
Note: If your tires show uneven wear ask an authorized dealer to check
for and correct any wheel misalignment, tire imbalance or mechanical
problem involved before tire rotation.
Note: Your vehicle may be equipped with a dissimilar spare tire/wheel. A
dissimilar spare tire/wheel is defined as a spare tire and/or wheel that is
different in brand, size or appearance from the road tires and wheels. If
you have a dissimilar spare tire/wheel it is intended for temporary use
only and should not be used in a tire rotation.
Note: After having your tires rotated, inflation pressure must be checked
and adjusted to the vehicle requirements.
WARNING: If the tire label shows different tire pressures for
the front and rear tires and the vehicle is equipped with TPMS
(tire pressure monitoring system), then the settings for the TPMS
sensors need to be updated. Always perform the TPMS reset procedure
after tire rotation. If the system is not reset, it may not provide a low
tire pressure warning when necessary. See the TPMS reset procedure
in this chapter.Tires, Wheels and Loading

TPMS reset procedure
The TPMS reset procedure needs to be performed after each tire
rotation on vehicles that require different recommended tire
pressures in the front tires as compared to the rear tires.
WARNING: To determine the required pressure(s) for your
vehicle – refer to the Safety Compliance Certification Label or
Tire Label located on the B-Pillar or the edge of the driver’s door. See
Vehicle loading in this chapter for more information.
Overview
To provide the vehicle’s load carrying capability, some vehicles require
different recommended tire pressures in the front tires as compared to
the rear tires. The Tire Pressure Monitoring System (TPMS) equipped on
these vehicles is designed to illuminate the Low Tire Pressure Warning
indicator at two different pressures; one for the front tires and one for
the rear tires.
Since tires need to be rotated to provide consistent performance and
maximum tire life, the Tire Pressure Monitoring System needs to know
when the tires are rotated to determine which set of tires are on the
front and which are on the rear. With this information, the system can
detect and properly warn of low tire pressures.
TPMS reset tips:
• To reduce the chances of interference from another vehicle, the TPMS
reset procedure should be performed at least 3 feet (1 meter) away
from another Ford Motor Company vehicle undergoing the TPMS reset
procedure at the same time.
• Do not wait more than two (2) minutes between resetting each tire
sensor or the system will timeout and the entire procedure will have
to be repeated on all four wheels.
• A double horn chirp indicates the need to repeat the procedure.
Performing the TPMS reset procedure
It is recommended that you read the entire procedure before attempting.
1. Drive the vehicle above 20 mph (32 km/h) for at least 2 minutes and
then park in a safe location where you can easily get to all four tires and
have access to an air pump.
2. Place the ignition in the off position and keep the key in the ignition. Tires, Wheels and Loading

8. Remove the valve cap from the valve stem on the right rear tire.
Decrease the air pressure until the horn sounds.
9. Remove the valve cap from the valve stem on the left rear tire.
Decrease the air pressure until the horn sounds.
Training is complete after the horn sounds for the last tire trained
(driver’s side rear tire), the TPMS tell tale stops flashing, and the
message center (if equipped) displays:
TRAINING COMPLETE .
10. Turn the ignition off. If two short horn beeps are heard, the reset
procedure was unsuccessful and must be repeated.
If after repeating the procedure and two short beeps are heard when the
ignition is turned to off, seek assistance from your authorized dealer.
11. Set all four tires to the recommended air pressure as indicated on
the Safety Compliance Certification Label or Tire Label located on the
B-Pillar or the edge of the driver’s door. See Vehicle loading - with and
without a trailer in this chapter for more information.
SNOW TIRES AND CHAINS
WARNING: Snow tires must be the same size, load index, speed
rating 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.
Note: Do not use snow chains on vehicles with 20 inch wheels and tires.
The tires on your vehicle have all weather treads to provide traction in
rain and snow. However, in some climates, you may need to use snow
tires and chains. If you need to use chains, it is recommended that steel
wheels (of the same size and specifications) be used, as chains may chip
aluminum wheels. Tires, Wheels and Loading

WARNING: Exceeding any vehicle weight rating limitation could
result in serious damage to the vehicle and/or personal injury.
Steps for determining the correct load limit:
1. Locate the statement “The combined weight of occupants and cargo
should never exceed XXX kg or XXX lb.” on your vehicle’s placard.
2. Determine the combined weight of the driver and passengers that will
be riding in your vehicle.
3. Subtract the combined weight of the driver and passengers from XXX
kg or XXX lb.
4. The resulting figure equals the available amount of cargo and luggage
load capacity. For example, if the “XXX” amount equals 1,400 lb. and
there will be five 150 lb. passengers in your vehicle, the amount of
available cargo and luggage load capacity is 650 lb. (1400-750 (5 x 150) =
650 lb.). In metric units (635-340 (5 x 68) = 295 kg.)
5. Determine the combined weight of luggage and cargo being loaded on
the vehicle. That weight may not safely exceed the available cargo and
luggage load capacity calculated in Step 4.
6. If your vehicle will be towing a trailer, load from your trailer will be
transferred to your vehicle. Consult this manual to determine how this
reduces the available cargo and luggage load capacity of your vehicle.
The following gives you a few examples on how to calculate the available
amount of cargo and luggage load capacity:
• Another example for your vehicle with 1,400 lb. (635 kg) of cargo and
luggage capacity. You decide to go golfing. Is there enough load
capacity to carry you, 4 of your friends and all the golf bags? You and
four friends average 220 lb. (99 kg) each and the golf bags weigh
approximately 30 lb. (13.5 kg) each. The calculation would be: 1400 -
(5 x 220) - (5 x 30) = 1400 - 1100 - 150 = 150 lb. Yes, you have
enough load capacity in your vehicle to transport four friends and
your golf bags. In metric units, the calculation would be: 635 kg - (5 x
99 kg) - (5 x 13.5 kg) = 635 - 495 - 67.5 = 72.5 kg.
• A final example for your vehicle with 1,400 lb. (635 kg) of cargo and
luggage capacity. You and one of your friends decide to pick up
cement from the local home improvement store to finish that patio
you have been planning for the past 2 years. Measuring the inside of
the vehicle with the rear seat folded down, you have room for
12-100 lb. (45 kg) bags of cement. Do you have enough load capacityTires, Wheels and Loading
