USING ALL-WHEEL DRIVE
All-wheel drive uses all four wheels to
power the vehicle. This increases traction,
enabling you to drive over terrain and road
conditions that a conventional two-wheel
drive vehicle cannot. The AWD system is
active all the time and requires no input
from the operator.
Note:
Your AWD vehicle is not intended for
off-road use. The AWD feature gives your
vehicle some limited off-road capabilities
in which driving surfaces are relatively level,
obstruction-free and otherwise similar to
normal on-road driving conditions.
Operating your vehicle under other than
those conditions could subject the vehicle
to excessive stress which might result in
damage which is not covered under your
warranty. Note:
When an AWD system fault is
present, the warning Check AWD displays
in the information display. The AWD system
is not functioning correctly and defaults to
front-wheel drive. When this warning
displays, have your vehicle serviced at an
authorized dealer.
Note: The
AWD OFF message may also
appear in the information display if the AWD
system overheats and defaults to
front-wheel drive. This may occur if the
vehicle is operated in extreme conditions
with excessive wheel slip, such as deep
sand. To resume normal AWD function as
soon as possible, stop the vehicle in a safe
location and stop the engine for at least 10
minutes. After the engine has been
restarted and the AWD system has
adequately cooled, the AWD OFF message
will turn off and normal AWD function
returns. If the engine is not stopped, the
AWD OFF
message turns off when the
system cools and normal AWD function
returns.

normal operation and clears this message
after you install the road tire and you switch
the ignition on and off, or after you allow
the system to cool. If this message remains
on, have a qualified technician service your
vehicle to repair other vehicle systems.
Displayed in conjunction with the power-
train malfunction/reduced power light
when the system is not operating properly.
If the warning stays on or continues to
come on, contact your authorized dealer
as soon as possible.
Check AWD
Operating AWD Vehicles With
Spare Tires
A spare tire of a different size other than
the tire provided should never be used. The
AWD system may disable automatically
and enter front-wheel drive only mode to
protect driveline components if a non-full
sized tire is installed. This condition may
display an AWD OFF message in the
information display. If there is an AWD OFF
message in the information display from
using a non-full sized spare tire, this
indicator should turn off after reinstalling
the repaired or replaced normal road tire
and cycling the ignition off and on. It is
recommended to reinstall the repaired or
replaced road tire as soon as possible.
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 front-wheel drive or damage
the AWD system. Operating 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.

system has adequately cooled, the AWD
OFF message turns off and normal AWD
function returns. In the event the engine is
not stopped, the AWD OFF message turns
off when the system cools and normal
AWD function returns.
When driving at slow speeds in deep sand
under high outside temperatures, use L
(Low) gear when possible. L (Low) gear
operation will maximize the engine and
transmission cooling capability.
Under severe operating conditions, the A/C
may cycle on and off to protect
overheating of the engine.
Avoid excessive speed because vehicle
momentum can work against you and
cause the vehicle to become stuck to the
point that assistance may be required from
another vehicle. Remember, you may be
able to back out the way you came if you
proceed with caution.
Mud and Water
If you must drive through high water, drive
slowly. Traction or brake capability may
be limited.
When driving through water, determine the
depth; avoid water higher than the bottom
of the wheel rims (for cars) or the bottom
of the hubs (for trucks) (if possible) and
proceed slowly. If the ignition system gets
wet, the vehicle may stall.
Once through water, always try the brakes.
Wet brakes do not stop the vehicle as
effectively as dry brakes. Drying can be
improved by moving your vehicle slowly
while applying light pressure on the brake
pedal. Be cautious of sudden changes in vehicle
speed or direction when you are driving in
mud. Even AWD vehicles can lose traction
in slick mud. As when you are driving over
sand, apply the accelerator slowly and
avoid spinning your wheels. If the vehicle
does slide, steer in the direction of the slide
until you regain control of the vehicle.
After driving through mud, clean off residue
stuck to rotating driveshafts and tires.
Excess mud stuck on tires and rotating
driveshafts causes an imbalance that
could damage drive components.
Note:
Driving through deep water may
damage the transmission.
If the front or rear axle is submerged in
water, have the power transfer unit (PTU)
or rear axle serviced by an authorized
dealer. “Tread Lightly
” is an educational program
designed to increase public awareness of
land-use regulations and responsibilities
in our nations wilderness areas. Ford Motor
Company joins the U.S. Forest Service and
the Bureau of Land Management in
encouraging you to help preserve our
national forest and other public and private
lands by “treading lightly. ”
Driving on Hilly or Sloping Terrain
Note: Avoid driving crosswise or turning on
steep slopes or hills. A danger lies in losing
traction, slipping sideways and possibly
rolling over. Whenever driving on a hill,
determine beforehand the route you will
use. Do not drive over the crest of a hill
without seeing what conditions are on the
other side. Do not drive in reverse over a hill
without the aid of an observer.

HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
The anti-lock braking system does not
eliminate the risks when:
•
You drive too closely to the vehicle in
front of you.
• Your vehicle is hydroplaning.
• You take corners too fast.
• The road surface is poor.
Note: If the system activates, the brake
pedal may pulse and may travel further.
Maintain pressure on the brake pedal. You
may also hear a noise from the system. This
is normal.
PARKING BRAKE WARNING: Always set the parking
brake fully and make sure the transmission
is locked in park (P). Failure to set the
parking brake and engage park could result
in vehicle roll-away, property damage or
bodily injury.
To set the parking brake, press the parking
brake pedal down to its fullest extent. The
brake warning lamp in the instrument
cluster will illuminate and remains
illuminated until the parking brake is
released.
To release the parking brake, press the
parking brake pedal down again.
If you are parking your vehicle on a grade
or with a trailer, press and hold the brake
pedal down, then set the parking brake.
There may be a little vehicle movement as
the parking brake sets to hold the vehicle's
weight. This is normal and should be no
reason for concern. If needed, press and hold the service brake pedal down, then
try reapplying the parking brake. Chock the
wheels if required. If the parking brake
cannot hold the weight of the vehicle, the
parking brake may need to be serviced or
the vehicle may be overloaded.

PRINCIPLE OF OPERATION
The traction control system helps avoid
drive wheel spin and loss of traction.
If your vehicle begins to slide, the system
applies the brakes to individual wheels
and, when needed, reduces engine power
at the same time. If the wheels spin when
accelerating on slippery or loose surfaces,
the system reduces engine power in order
to increase traction.
USING TRACTION CONTROL
WARNING: The stability and traction
control light illuminates steadily if the
system detects a failure. Make sure you
did not manually disable the traction
control system using the information
display controls or the switch. If the
stability control and traction control light
is still illuminating steadily, have the
system serviced by an authorized dealer
immediately. Operating your vehicle with
the traction control disabled could lead to
an increased risk of loss of vehicle control,
vehicle rollover, personal injury and death.
The system automatically turns on each
time you switch the ignition on.
If your vehicle is stuck in mud or snow,
switching traction control off may be
beneficial as this allows the wheels to spin.
Note: When you switch traction control off,
stability control remains fully active.
Switching the System Off
When you switch the system off or on, a
message appears in the information
display showing system status.
You can switch the system off by either
using the information display controls or
the switch. Using the Information Display
Controls
You can switch this feature off or on in the
information display. See General
Information (page 95).
Using a Switch
(If Equipped)
Use the traction control switch on the
instrument panel to switch the system off
or on.
System Indicator Lights and
Messages The stability and traction control
light:
• Temporarily illuminates on engine
start-up.
• Flashes when a driving condition
activates either of the systems.
• Illuminates if a problem occurs in either
of the systems. The stability and traction control
off light temporarily illuminates
on engine start-up and stays on
when you switch the traction control
system off.

by a tone. Occasional system messages
may occur in normal operation. For
recurring or frequent system faults, contact
an authorized dealer to have your vehicle
serviced.
Troubleshooting the System The system does not look for a space
The traction control system may be off.
The transmission is in reverse (R). Your vehicle must be moving forward to detect a
parking space. The system does not offer a particular space
The sensors may be covered. For example, with snow, ice or dirt. Covered sensors can
affect the system's functionality
There is not enough room in the parking space for your vehicle to safely park.
There is not enough space for the parking maneuver on the opposite side of the parking
space.
The parking space is farther than
5 ft (1.5 m) or closer than 16 in (40 cm) away.
Your vehicle is going faster than
22 mph (35 km/h).
You may have recently disconnected or replaced the battery. After a battery disconnect,
the vehicle must be driven on a straight road for a short period of time.

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 by an authorized dealer. WARNING: If the system detects an
error, you may not feel a difference in the
steering, however a serious condition may
exist. Obtain immediate service from an
authorized dealer, failure to do so may
result in loss of steering control.
Your vehicle has an electric power steering
system. There is no fluid reservoir. No
maintenance is required.
If your vehicle loses electrical power while
you are driving, electric power steering
assistance is lost. The steering system still
operates and you can steer your vehicle
manually. Manually steering your vehicle
requires more effort.
Extreme continuous steering may increase
the effort required for you to steer your
vehicle. This increased effort prevents
overheating and permanent damage to
the steering system. You do not lose the
ability to steer your vehicle manually.
Typical steering and driving maneuvers
allow the system to cool and return to
normal operation. Steering Tips
If the steering wanders or pulls, check for:
•
Correct tire pressures.
• Uneven tire wear.
• Loose or worn suspension
components.
• Loose or worn steering components.
• Improper vehicle alignment.
Note: A high crown in the road or high
crosswinds may also make the steering
seem to wander or pull.
Adaptive Learning
The electronic power steering system
adaptive learning helps correct road
irregularities and improves overall handling
and steering feel. It communicates with
the brake system to help operate
advanced stability control and accident
avoidance systems. Additionally, whenever
the battery is disconnected or a new
battery installed, you must drive your
vehicle a short distance before the system
relearns the strategy and reactivates all
systems.
COLLISION WARNING SYSTEM
(If Equipped)
PRINCIPLE OF OPERATION WARNING: This system is designed
to be a supplementary driving aid. It is not
intended to replace the driver ’s attention,
and judgment, or the need to apply the
brakes. This system does NOT activate the
brakes automatically. Failure to press the
brake pedal to activate the brakes may
result in a collision.
