LIMITED-SLIP AXLE (IF EQUIPPED)
This axle provides added traction on slippery surfaces, particularly when
one wheel is on a poor traction surface. Under normal conditions, the
limited slip axle functions like a standard rear axle.
Extended use of other than the manufacturer ’ s specified size tires on a
limited slip rear axle could result in a permanent reduction in
effectiveness. This loss of effectiveness does not affect normal driving
and should not be noticeable to the driver.
PREPARING TO DRIVE YOUR VEHICLE
Utility vehicles have a significantly higher rollover rate than
other types of vehicles.
In a rollover crash, an unbelted person is significantly more likely
to die than a person wearing a seat belt.
Your vehicle has special design and equipment features to make it
capable of performing in a wide variety of circumstances. These special
design features, such as larger tires and increased ground clearance, give
the vehicle a higher center of gravity than a passenger car.

Tires, Replacement Requirements
Do not use a size and type of tire and wheel other than that
originally provided by Ford Motor Company 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, and/or serious
personal injury or death.
Make sure all road tires and road wheels on the vehicle are of the same
size, type, tread design and load carrying capacity (for information on
the spare tire, refer to Changing the Tires in the Roadside
emergencies chapter). If you have questions regarding tire replacement,
see an authorized Ford or Lincoln/Mercury dealer.
If you nevertheless decide to equip your four – wheel drive for off-road
use with tires larger than what Ford Motor Company recommends, you
should not use these tires for highway driving.
If you use any tire/wheel combination not recommended by Ford Motor
Company, it may adversely affect vehicle handling and could cause
steering, suspension, axle or transfer case failure as well as the increased
risk of loss of vehicle control.
Do not use “ aftermarket lift kits ” or other suspension modifications,
whether or not they are used with larger tires and wheels.
These “ aftermarket lift kits ” could adversely affect the vehicle ’ s handling
characteristics, which could lead to loss of vehicle control or rollover and
serious injury.
Tires can be damaged during off-road use. For your safety, tires that are
damaged should not be used for highway driving because they are more
likely to blow out or fail.
You should carefully observe the recommended tire inflation pressure
found on the safety compliance certification label attached to the left
front door latch post pillar (a label may also be found on the fuel cap
filler door). Failure to follow tire pressure recommendations can
adversely affect the way your vehicle handles. Do not exceed the Ford
Motor Company recommended pressure even if it is less than the
maximum pressure allowed for the tire.

CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
The use of tire sealants may damage your tires. The use of tire
sealants may also damage your tire pressure monitoring system
(if equipped).
Your vehicle may be equipped with a conventional spare tire that is
different in one or more of the following: type, brand, size, speed rating
and tread design. If this is the case, this dissimilar spare tire is still rated
for your vehicle loads (GAWR and GVWR). Your vehicle is equipped with
a spare wheel that does not match the road wheels and is not equipped
with a Tire Pressure Monitor System (TPMS) sensor.
Spare tire information
Note: If your vehicle is equipped with the tire pressure monitoring
system (TPMS), the system indicator light will illuminate when the spare
is in use. To restore the full functionality of the monitoring system, all
road wheels equipped with tire pressure monitoring sensors must be
mounted on the vehicle
If your vehicle is equipped with TPMS, have a flat tire serviced by a
dealer or qualified technician in order to prevent damage to the TPMS
sensor. Replace the spare tire with a road tire as soon as possible.
Location of the spare tire and tools
The spare tire and tools for your vehicle are stowed in the following
locations:
Item Location
Spare tire Under the vehicle, just forward of
the rear bumper
Jack tools and jacking instructions Under the access panel located in
the floor compartment behind the
rear seat

2. Slide the wheel partially under
the vehicle and install the retainer
through the wheel center. After
doing so, pull on the cable to align
the components at the end of the
cable.
3. Assemble the jack handle and
winch extension (as shown in
illustration), then insert the winch
extension through the access hole
behind the 3rd row seat and engage
the winch.
4. Turn the jack handle clockwise
until the tire is raised to its stowed
position underneath the vehicle. The
wrench will become harder to turn and the spare tire winch will ratchet
or slip when the tire is raised to maximum tightness. A clicking sound
will be heard from the winch indicating that the tire is properly stowed.
5. Disassemble the tools and snap them back into the tool tray. Close the
access hole with the rubber plug. Reinstall the tray into the vehicle and
secure it with the wing nut (turn clockwise until tight).
Wheel lug nut torque specifications
Retighten the lug nuts to the specified torque at 800 km (500 miles)
after any wheel disturbance (tire rotation, changing a flat tire, wheel
removal, etc.).
Bolt size Wheel lug nut torque*
Nm Lb-ft1
2
x 20 113-153 84-114
* Torque specifications are for nut and bolt threads free of dirt and
rust. Use only Ford recommended replacement fasteners.
When a wheel is installed, always remove any corrosion, dirt or
foreign materials present on the mounting surfaces of the wheel
or the surface of the front disc brake hub and rotor that contacts the
wheel. Installing wheels without correct metal-to-metal contact at the
wheel mounting surfaces can cause the wheel nuts to loosen and the
wheel to come off while the vehicle is in motion, resulting in loss of
control.

Habits
• Smooth, moderate operation can yield up to 10% savings in fuel.
• Steady speeds without stopping will usually give the best fuel
economy.
• Idling for long periods of time (greater than one minute) may waste
fuel.
• Anticipate stopping; slowing down may eliminate the need to stop.
• Sudden or hard accelerations may reduce fuel economy.
• Slow down gradually.
• Driving at reasonable speeds (traveling at 88 km/h [55 mph] uses 15%
less fuel than traveling at 105 km/h [65 mph]).
• Revving the engine before turning it off may reduce fuel economy.
• Using the air conditioner or defroster may reduce fuel economy.
• You may want to turn off the speed control in hilly terrain if
unnecessary shifting between third and fourth gear occurs.
Unnecessary shifting of this type could result in reduced fuel
economy.
• Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
• Resting your foot on the brake pedal while driving may reduce fuel
economy.
• Combine errands and minimize stop-and-go driving.
Maintenance
• Keep tires properly inflated and use only recommended size.
• Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
• Use recommended engine oil. Refer to Lubricant specifications in
this chapter.
• Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in your vehicle scheduled maintenance guide.
Conditions
• Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
• Carrying unnecessary weight may reduce fuel economy (as much as
0.4 km/L [1 mpg] is lost for every 180 kg [400 lb] of weight carried).

government test course. For example, a tire graded 150 would wear one
and one-half (1 1/2) times as well on the government course as a tire
graded 100. The relative performance of tires depends upon the actual
conditions of their use, however, and may depart significantly from the
norm due to variations in driving habits, service practices, and
differences in road characteristics and climate.
Traction AA A B C
The traction grades, from highest to lowest are AA, A, B, and C. The
grades represent the tire ’ s ability to stop on wet pavement as measured
under controlled conditions on specified government test surfaces of
asphalt and concrete. A tire marked C may have poor traction
performance.
The traction grade assigned to this tire is based on
straight-ahead braking traction tests, and does not include
acceleration, cornering, hydroplaning or peak traction characteristics.
Temperature A B C
The temperature grades are A (the highest), B and C, representing the
tire ’ s resistance to the generation of heat and its ability to dissipate heat
when tested under controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the material of the tire
to degenerate and reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to a level of performance
which all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by
law.
The temperature grade for this tire is established for a tire that
is properly inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either separately or in
combination, can cause heat buildup and possible tire failure.
TIRES
Tires are designed to give many thousands of miles of service, but they
must be maintained in order to get the maximum benefit from them.
Glossary of tire terminology
• Tire label: A label showing the OE (Original Equipment) tire sizes,
recommended inflation pressure and the maximum weight the vehicle
can carry.

• Tire Identification Number (TIN): A number on the sidewall of
each tire providing information about the tire brand and
manufacturing plant, tire size and date of manufacturer.
• Inflation pressure: A measure of the amount of air in a tire.
• Standard load: A class of P-metric or Metric tires designed to carry a
maximum load at 35 psi [37 psi (2.5 bar) for Metric tires]. Increasing
the inflation pressure beyond this pressure will not increase the tires
load carrying capability.
• Extra load: A class of P-metric or Metric tires designed to carry a
heavier maximum load at 41 psi [43 psi (2.9 bar) for Metric tires].
Increasing the inflation pressure beyond this pressure will not increase
the tires load carrying capability.
• kPa: Kilopascal, a metric unit of air pressure.
• PSI: Pounds per square inch, a standard unit of air pressure.
• B-pillar: The structural member at the side of the vehicle behind the
front door.
• Bead area of the tire: Area of the tire next to the rim.
• Sidewall of the tire: Area between the bead area and the tread.
• Tread area of the tire: Area of the perimeter of the tire that
contacts the road when mounted on the vehicle.
• Rim: The metal support (wheel) for a tire or a tire and tube assembly
upon which the tire beads are seated.
INFORMATION CONTAINED ON THE TIRE SIDEWALL
Federal law requires 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
tire identification number for safety standard certification and in case of
a recall.

Information on “ P ” type tires
P215/65R15 95H is an example of a
tire size, load index and speed
rating. The definitions of these
items are listed below. (Note that
the tire size, load index and speed
rating for your vehicle may be
different than this example.)
1. P: Indicates a tire, designated by
the Tire and Rim Association
(T&RA), that maybe used for
service on cars, SUVs, minivans and
light trucks.
Note: If your tire size does not
begin with a letter this may mean it
is designated by either ETRTO (European Tire and Rim Technical
Organization) or JATMA (Japan Tire Manufacturing Association).
2. 215: Indicates the nominal width of the tire in millimeters from
sidewall edge to sidewall edge. In general, the larger the number, the
wider the tire.
3. 65: Indicates the aspect ratio which gives the tire ’ s ratio of height to
width.
4. R: Indicates a “ radial ” type tire.
5. 15: Indicates the wheel or rim diameter in inches. If you change your
wheel size, you will have to purchase new tires to match the new wheel
diameter.
6. 95: Indicates the tire ’ s load index. It is an index that relates to how
much weight a tire can carry. You may find this information in your
owner ’ s guide. If not, contact a local tire dealer.
Note: You may not find this information on all tires because it is not
required by federal law.
7. 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 159 km/h (99 mph) to 299 km/h
(186 mph). 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.
