TIRE PRESSURE MONITORING SYSTEM (TPMS)
Each tire, including the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label. (If your vehicle has tires
of a different size than the size indicated on the vehicle placard or tire
inflation pressure label, you should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS) that illuminates a low tire pressure
telltale when one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible, and inflate them to the
proper pressure. Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure. Under-inflation also reduces
fuel efficiency and tire tread life, and may affect the vehicle’s handling
and stopping ability.
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility to maintain correct tire
pressure, even if under-inflation has not reached the level to trigger
illumination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator
to indicate when the system is not operating properly. The TPMS
malfunction indicator is combined with the low tire pressure telltale.
When the system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously illuminated.
This sequence will continue upon subsequent vehicle start-ups as long as
the malfunction exists.
When the malfunction indicator is illuminated, the system may not be
able to detect or signal low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the installation of
replacement or alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the TPMS malfunction
telltale after replacing one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and wheels allow the
TPMS to continue to function properly.
The Tire Pressure Monitoring System complies with part 15 of the FCC
rules and with RSS-210 of Industry Canada. Operation is subject to the

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.
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.
Follow these guidelines when using snow tires and chains:
• Use only cable type chains or chains offered by Ford as an accessory
or equivalent. Other conventional link type chains may contact and
cause damage to the vehicle’s wheel house and/or body.
• Do not install chains on the front wheels. Chains on the front wheels
may interfere with suspension components.
• Chains are not recommended for use on the P275/55R20 tire.
• Install chains securely, verifying that the chains do not touch any
wiring, brake lines or fuel lines.
• Drive cautiously. If you hear the chains rub or bang against your
vehicle, stop and re-tighten the chains. If this does not work, remove
the chains to prevent damage to your vehicle.
• If possible, avoid fully loading your vehicle.
• Remove the tire chains when they are no longer needed. Do not use
tire chains on dry roads.
• The suspension insulation and bumpers will help prevent vehicle
damage. Do not remove these components from your vehicle when
using snow tires and chains.
• Do not exceed 30 mph (48 km/h) with tire chains on your vehicle.
VEHICLE LOADING – WITH AND WITHOUT A TRAILER
This section will guide you in the proper loading of your vehicle and/or

Pull the release lever to release the
brake. Driving with the parking
brake on will cause the brakes to
wear out quickly and reduce fuel
economy.
ADVANCETRAC  WITH ROLL STABILITY CONTROL™ (RSC  )
STABILITY ENHANCEMENT SYSTEM (IF EQUIPPED)
WARNING: Vehicle modifications involving braking system,
aftermarket roof racks, suspension, steering system, tire
construction and/or wheel/tire size may change the handling
characteristics of the vehicle and may adversely affect the performance
of the AdvanceTrac
with RSC
system. In addition, installing any
stereo loudspeakers may interfere with and adversely affect the
AdvanceTrac
with RSC
system. Install any aftermarket stereo
loudspeaker as far as possible from the front center console, the
tunnel, and the front seats in order to minimize the risk of interfering
with the AdvanceTrac
with RSC
sensors. Reducing the effectiveness
of the AdvanceTrac
with RSC
system could lead to an increased risk
of loss of vehicle control, vehicle rollover, personal injury and death.
WARNING: Remember that even advanced technology cannot
defy the laws of physics. It’s always possible to lose control of a
vehicle due to inappropriate driver input for the conditions. Aggressive
driving on any road condition can cause you to lose control of your
vehicle increasing the risk of personal injury or property damage.
Activation of the AdvanceTrac
with RSC
system is an indication that
at least some of the tires have exceeded their ability to grip the road;
this could reduce the operator’s ability to control the vehicle,
potentially resulting in a loss of vehicle control, vehicle rollover,
personal injury and death. If your AdvanceTrac
with RSC
system
activates, SLOW DOWN.

AIR SUSPENSION SYSTEM (IF EQUIPPED)
The air suspension system is designed to improve ride, handling and
general vehicle performance during:
• Certain road conditions
• Steering maneuvers
• Braking
• Acceleration
This system keeps the rear of your vehicle at a constant level by
automatically adding air or releasing air from the springs. If you exceed
the load limit, the rear air suspension may not operate. The air
suspension system will stay active for 40 minutes after the ignition is
turned off to accommodate any load changes. (The air compressor may
run when the vehicle is off; this is normal.)
The air suspension system can be enabled or disabled through the
message center. Refer to Message center in the Driver Controls chapter.
If the system is off, the rear air suspension will not operate and will not
raise (pump) or lower (vent) while the vehicle is not moving. However, if
the system determines that the vehicle is low or high and needs to make
a height adjustment while driving at speeds above 15 mph (24 km/h), the
system will pump or vent as required. Normal vehicle operation does not
require any action by the driver.
WARNING: On vehicles equipped with air suspension, turn the
air suspension and the ignition switch off prior to jacking,
hoisting or towing your vehicle.
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
WARNING: Utility vehicles have a significantly higher rollover
rate than other types of vehicles.

WARNING: Refer to Tire pressure monitoring system (TPMS)
in the Tires, Wheels and Loading chapter for important
information. If the tire pressure monitor sensor becomes damaged, it
will no longer function.
Dissimilar spare tire/wheel information
WARNING: Failure to follow these guidelines could result in an
increased risk of loss of vehicle control, injury or death.
If you have a dissimilar spare tire/wheel, then it is intended for
temporary use only. This means that if you need to use it, you should
replace it as soon as possible with a road tire/wheel that is the same size
and type as the road tires and wheels that were originally provided by
Ford. If the dissimilar spare tire or wheel is damaged, it should be
replaced rather than repaired.
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
and can be one of three types:
1. T-type mini-spare: This spare tire begins with the letter “T” for tire
size and may have “Temporary Use Only” molded in the sidewall

WHEEL LUG NUT TORQUE SPECIFICATIONS
Retighten the lug nuts to the specified torque within 100 miles (160 km)
after any wheel disturbance (tire rotation, changing a flat tire, wheel
removal, etc.).
Bolt size Wheel lug nut torque*
lb.ft. N • m
M14 x 2.0 150 200
* Torque specifications are for nut and bolt threads free of dirt and
rust. Use only Ford recommended replacement fasteners.
WARNING: 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 wheel hub, brake drum or
brake disc that contacts the wheel. Ensure that any fasteners that
attach the rotor to the hub are secured so they do not interfere with
the mounting surfaces of 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.
Note: Inspect the wheel pilot hole
prior to installation. If there is
visible corrosion in wheel pilot hole,
remove loose particles by wiping
with clean rag and apply grease.
Apply grease only to the wheel pilot
hole surface by smearing a “dime”
(1 square cm) sized glob of grease
around the wheel pilot surface (1)
with end of finger. DO NOT apply
grease to lugnut/stud holes or
wheel-to-brake surfaces.

• You may want to turn off the speed control in hilly terrain if
unnecessary shifting between the top gears 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 Maintenance product
specifications and capacities in this chapter.
• Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in scheduled maintenance information.
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
1 mpg [0.4 km/L] is lost for every 400 lb [180 kg] of weight carried).
• Adding certain accessories to your vehicle (for example; bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
• Using fuel blended with alcohol may lower fuel economy.
• Fuel economy may decrease with lower temperatures during the first
8–10 miles (12–16 km) of driving.
• Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
• Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
• Four-wheel-drive operation (if equipped) is less fuel efficient than
two-wheel-drive operation.
• Close windows for high speed driving.
