Operating ALL-Wheel drive (AWD)
Vehicles with Mismatched Tires
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
(affixed to either the door hinge pillar,
door-latch post, or the door edge that
meets the door-latch post, next to the
driver's seating position), 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. Major dissimilar tire sizes between the front
and rear axles (for example, 17 inch low
profile tires on the front axle and 22 inch high
profile tires on the rear axle) could cause the
AWD system to stop functioning and default
to rear-wheel drive or damage the AWD
system.
For optimum AWD Performance, it is
recommended to follow the tire rotation
maintenance schedule. To avoid potential
AWD malfunction or AWD system damage,
it is recommended to replace all four tires
rather than mixing significantly worn tires
with new tires. For example, using 3 worn
tread tires and 1 new tread tire all of the same
original tire size/brand, can be tolerated by
the AWD system as long as the worn tires
still have usable tread depth.
How Your Vehicle Differs from Other
Vehicles
Truck and utility vehicles can differ from
some other vehicles. Your vehicle could be
higher to allow it to travel over rough terrain
without getting hung up or damaging
underbody components. The differences that make your vehicle so
versatile also make it handle differently than
an ordinary passenger car.
Maintain steering wheel control at all times,
especially in rough terrain. Since sudden
changes in terrain can result in abrupt
steering wheel motion, make sure you grip
the steering wheel from the outside. Do not
grip the spokes.
Drive cautiously to avoid vehicle damage
from concealed objects such as rocks and
stumps.
You should either know the terrain or
examine maps of the area before driving.
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.

(If Equipped)

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. The
front wheels have to be turning in order to
steer the vehicle.
Your vehicle has anti-lock brakes, therefore
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 your vehicle slides while cornering, steer
in the direction of the slide until you regain
control of your vehicle. Note:
Excessive tire slippage can cause
driveline damage.
AWD 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 an
AWD vehicle could accelerate better than a
two-wheel drive vehicle in snow and ice, it
will not 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.
Since your vehicle is equipped with a four
wheel (ABS), do not “pump
” the brakes. See
Hints on Driving With Anti-Lock Brakes
(page
258).
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, we strongly
recommend that you do not make
modifications such as adding or removing
parts (such as lowering kits or stabilizer bars)
or by using replacement parts not equivalent
to the original factory equipment.

STEERING
Electric Power Steering WARNING:
The electric power
steering system has diagnostic checks that
continuously monitor the system. If a fault
is detected, a message displays in the
information display. Stop your vehicle as
soon as it is safe to do so. Switch the ignition off. After at least 10 seconds,
switch the ignition on and watch the
information display for a steering system
warning message. If a steering system
warning message returns, have the system
checked as soon as possible.
WARNING: If the system detects an
error, you may not feel a difference in the
steering, however a serious condition may
exist. Have your vehicle checked as soon
as possible. Failure to do so may result in
loss of steering control. Your vehicle has an electric power steering
system. There is no fluid reservoir and
therefore requires no maintenance.
If your vehicle loses electrical power when
you are driving, electric power steering
assistance is lost. The steering system still
operates and you can manually steer your
vehicle. Manually steering your vehicle
requires more effort.

Special Loading Instructions for
Owners of Pick-up Trucks and Utility-
type Vehicles
WARNING: When loading the
roof racks, we recommend you evenly
distribute the load, as well as maintain
a low center of gravity. Loaded
vehicles, with higher centers of gravity,
may handle differently than unloaded
vehicles. Take extra precautions, such
as slower speeds and increased
stopping distance, when driving a
heavily loaded vehicle.
AIR SUSPENSION
(IF EQUIPPED) WARNING:
If your vehicle has
self-leveling air suspension, you must
switch the system off before carrying out
any maintenance or repair. Failure to follow
this warning could result in serious
personal injury or death. The air suspension system automatically
adjusts to maintain a constant frame height,
allows for ease of vehicle loading, provides
improved vehicle ride, and increased driver
comfort.
You can adjust different ride settings through
the selectable drive modes.
See Selecting
a Drive Mode (page 329).
Note: The air suspension system may not
operate properly if you exceed the load limit.
See
Load Limit (page 334).
Note: When your vehicle is off, the air
compressor may run for a short time. This is
normal.
Switching the systems on or off
You can access the air suspension, liftgate
and easy entry features through the
information display menu settings.
See
General Information (page 134).
Using the Service Mode
When the service mode is active, the air
suspension does not make any adjustments
while your vehicle is stationary. Note:
Always switch the air suspension
service mode to on before servicing your
vehicle.
Using Cargo Loading
The air suspension cargo loading feature
lowers your vehicle for easier access when
the system detects the liftgate is opening.
When the liftgate is closed your vehicle
returns to its normal height after a short time.
Note: To preserve your vehicle battery, your
vehicle may only lower for cargo mode one
to two times per ignition cycle.
Using Easy Entry
The air suspension can lower your vehicle
to an easier access entry height when the
system detects the intelligent access key,
you press the unlock button, use the remote
start, or use Phone as a Key.
The leveling process stops when you open
a door or the target level is achieved.
Note: To stop the leveling process, press the
lock button on the intelligent access key.

ESSENTIAL TOWING CHECKS
Follow these guidelines for safe towing:
•
Do not tow a trailer until you drive your
vehicle at least 1,000 mi (1,600 km).
• Consult your local motor vehicle laws for
towing a trailer.
• See the instructions included with towing
accessories for the proper installation
and adjustment specifications.
• Service your vehicle more frequently if
you tow a trailer.
See Scheduled
Maintenance (page 564).
• If you use a rental trailer, follow the
instructions the rental agency gives you.
You can find information on load
specification terms found on the tire label
and Safety Compliance label as well as
instructions on calculating your vehicle's load
in the Load Carrying chapter. See Load Limit
(page
334).
Remember to account for the trailer tongue
weight as part of your vehicle load when
calculating the total vehicle weight. Hitches
Do not use a hitch that either clamps onto
the bumper or attaches to the axle.
Distribute the trailer load so 10-15% of the
total trailer weight is on the tongue.
A weight distributing hitch is not required for
your vehicle.
Safety Chains
Note:
Do not attach safety chains to the
bumper.
Always connect the safety chains to the hook
retainers of your vehicle hitch.
To connect the trailer’ s safety chains, cross
them under the trailer tongue and allow
enough slack for turning tight corners. Do
not allow the chains to drag on the ground. Trailer Brakes WARNING:
Do not connect a trailer's
hydraulic brake system directly to your
vehicle's brake system. Your vehicle may
not have enough braking power and your
chances of having a collision greatly
increase.
Electric brakes and manual, automatic or
surge-type trailer brakes are safe if you install
them properly and adjust them to the
manufacturer's specifications. The trailer
brakes must meet local and federal
regulations.
The rating for the tow vehicle's braking
system operation is at the gross vehicle
weight rating, not the gross combined weight
rating.
Safe control of towed vehicles requires
separate functioning brake systems for
vehicles and trailers weighing more than
1,500 lb (680 kg)
when loaded.

REDUCED ENGINE PERFORMANCE
WARNING: If you continue to drive
your vehicle when the engine is
overheating, the engine could stop without
warning. Failure to follow this instruction
could result in the loss of control of your
vehicle.
If the engine coolant temperature gauge
needle moves to the upper limit position, the
engine is overheating.
See Gauges (page
126).
You must only drive your vehicle for a short
distance if the engine overheats. The
distance you can travel depends on ambient
temperature, vehicle load and terrain. The
engine continues to operate with limited
power for a short period of time.
If the engine temperature continues to rise,
the fuel supply to the engine reduces. The
air conditioning switches off and the engine
cooling fan operates continually. 1. Gradually reduce your speed and stop
your vehicle as soon as it is safe to do
so.
2. Immediately switch the engine off to prevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level.
See Engine
Coolant Check (page 390).
5. Have your vehicle checked as soon as possible.
ECONOMICAL DRIVING
Your fuel economy is affected by several
things, such as how you drive, the conditions
you drive under, and how you maintain your
vehicle.
You may improve your fuel economy by
keeping these things in mind:
• Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds without stopping.
• Anticipate stops; slowing down may
eliminate the need to stop. •
Combine errands and minimize
stop-and-go driving.
• Close the windows for high-speed
driving.
• Drive at reasonable speeds (traveling at
55 mph [88 km/h] uses 15% less fuel than
traveling at 65 mph [105 km/h]).
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.
Avoid these actions; they reduce your fuel
economy:
• Sudden accelerations or hard
accelerations.
• Revving the engine before turning it off.
• Idle for periods longer than one minute.
• Warm up your vehicle on cold mornings.
• Use the air conditioner or front defroster.
• Use the speed control in hilly terrain.
• Rest your foot on the brake pedal while
driving.
