The power point temporarily turns off power
if it exceeds the 150 watt limit. It can also
switch to a fault mode if it detects
overloading, overheating, or shorting
conditions. For overloading and shorting
conditions, unplug your device and switch
the ignition off then on. For an overheating
condition, let the system cool off first. Switch
the ignition off then on.
Do not use the power point for certain electric
devices, including:
•
Cathode ray tube type televisions
• Motor loads, for example vacuum
cleaners, electric saws and other electric
power tools, or compressor-driven
refrigerators
• Measuring devices which process precise
data, for example medical equipment or
measuring equipment
• Other appliances requiring an extremely
stable power supply, for example
microcomputer-controlled electric
blankets or touch sensor lamps

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 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 not covered under your
warranty.
Note: When an AWD system fault is present,
the warning Check AWD displays in the
information display. See Information
Messages (page 94). An AWD system fault
causes the AWD system to default to
front-wheel drive only mode. If this warning
displays, have your vehicle serviced at an
authorized dealer. Note:
The AWD Off message displays in the
information display if the AWD system has
overheated
See Information Messages
(page 94). This condition may occur if the
vehicle operates 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 restarts and the AWD system
has adequately cooled, the AWD Off message
turns off and normal AWD function returns. In
the event you do not stop the engine, the AWD
Off message turns off when the system cools
and normal AWD function returns.
Do not use a spare tire of a different size
other than the tire provided. The AWD system
may disable automatically and enter
front-wheel drive only mode to protect
driveline components if you install the
mini-spare tire. A warning in the information
display indicates this condition.
See
Information Messages (page 94). If there
is an AWD Off message in the information
display from using the spare tire, this
indicator should turn off after reinstalling the
repaired or replaced normal road tire and
cycling the ignition off and on. Reinstall the repaired or replaced road tire as soon as
possible. Major dissimilar tire sizes between
the front and rear axles could cause the AWD
system to stop functioning and default to
front-wheel drive or damage the AWD
system.
Driving In Special Conditions With
All-Wheel Drive (AWD)
AWD vehicles are equipped for driving on
sand, snow, mud and rough roads and have
operating characteristics that are somewhat
different from conventional vehicles, both on
and off the highway.
When driving at slow speeds in deep sand
under high outside temperatures, use a low
gear when possible. Lower gear operation
maximizes the engine and transmission
cooling capability. Under severe operating
conditions, the A/C may cycle on and off to
protect overheating of the engine.
Basic operating principles in special
conditions
•
Drive slower in strong crosswinds which
can affect the normal steering
characteristics of your vehicle.
• Use extreme care when driving on
pavement made slippery by loose sand,
water, gravel, snow or ice.
142
MKS (), enUSA All-Wheel Drive
(If Equipped)

steering, acceleration or braking which
could result in an increased risk of loss of
vehicle control, vehicle rollover and/or
personal injury. Use all available road
surface to return the vehicle to a safe
direction of travel.
• In the event of an emergency stop, avoid
skidding the tires and do not attempt any
sharp steering wheel movements.
• If the vehicle goes from one type of
surface to another (i.e., from concrete to
gravel) the way the vehicle responds to
a maneuver changes (steering,
acceleration or braking). Again, avoid
these abrupt inputs.
Sand
When driving over sand, try to keep all four
wheels on the most solid area of the trail.
Avoid reducing the tire pressures but shift to
a lower gear and drive steadily through the
terrain. Apply the accelerator slowly and
avoid excessive wheel slip.
Do not drive your vehicle in deep sand for an
extended period of time. This could cause
the AWD system to overheat and default to
front-wheel drive. If this occurs AWD Off
displays in the Information Display. 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 restarts and the AWD
system has adequately cooled, the AWD Off
message turns off and normal AWD function
returns. In the event you do not stop the
engine, 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 a low
gear when possible. Low gear operation
maximizes 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 improves
when you move your vehicle slowly while
applying light pressure on the brake pedal.
144
MKS (), enUSA All-Wheel Drive (If Equipped)E142667

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,
the axle lubricant and AWD PTU (Power
Transfer Unit) lubricant should be checked
and changed if necessary. “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 (R) over a hill without the aid of an
observer.
Although natural obstacles may make it
necessary to travel diagonally up or down a
hill or steep incline, you should always try to
drive straight up or straight down.
When climbing a steep slope or hill, start in
a lower gear rather than downshifting to a
lower gear from a higher gear once the ascent
has started. This reduces strain on the engine
and the possibility of stalling. If you do stall out, do not try to turn around
because you might roll over. It is better to
back down to a safe location.
Apply just enough power to the wheels to
climb the hill. Too much power can cause the
tires to slip, spin or lose traction, resulting in
loss of vehicle control.
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 (N); 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.

Overriding Adaptive Cruise Control
WARNING
Whenever the driver is overriding the
system by pressing the accelerator
pedal, the system will not
automatically apply the brakes to maintain
separation from any vehicle ahead. You can override the set speed and gap
distance by pressing the accelerator pedal.
When you override the system, the
green indicator light illuminates
and the lead vehicle graphic does
not show in the information
display.
The system will resume operation when you
release the accelerator pedal. The vehicle
speed will decrease to the set speed, or a
lower speed if following a slower vehicle. Changing the Set Speed
•
Accelerate or brake to the desired speed,
then press SET upward and release.
• Increase or decrease the speed by holding
SET
upward or downward SET until the
desired set speed shows on the
information display. The vehicle speed
will gradually change to the selected
speed.
• Increase or decrease the speed in
increments of 1 mph (2km/h) by briefly
pressing
SET upward or downward.
The system may apply the brakes to slow
your vehicle to the new set speed. The set
speed will display continuously in the
information display while the system is
active.
Resuming the Set Speed
Note: Only use resume if you are aware of the
set speed and intend to return to it.
Press and release RES. The vehicle will return
to the previously set speed. The set speed
will display continuously in the information
display while the system is active. Low Speed Automatic Cancellation
The system is not functional at vehicle
speeds below 16 mph (26 km/h). An audible
alarm will sound and the automatic braking
releases if the vehicle drops below this speed.
Hilly Condition Usage
Note:
An audible alarm will sound and the
system will shut down if it is applying brakes
for an extended period of time. This allows the
brakes to cool down. The system will function
normally again when the brakes have cooled
down.
You should select a lower gear position when
the system is active in situations such as
prolonged downhill driving on steep grades,
for example in mountainous areas. The
system needs additional engine braking in
these situations to reduce the load on the
vehicle ’s regular brake system to prevent
them from overheating.
Switching the System Off
Note: The set speed memory erases when
you switch off the system.
Press and release OFF or turn off the ignition.
167
MKS (), enUSA Cruise ControlE144529

Switching the Systems Off and On
You can temporarily switch off one or both
systems in the information display. See
General Information (page 88). When you
switch off the Blind Spot Information System,
you do not receive alerts and the information
display shows a system off message. The
yellow alert indicator in the outside mirror
also flashes twice. The system turns back on
whenever you switch the ignition on.
You can also have one or both systems
switched off permanently at an authorized
dealer. Once switched off, only an authorized
dealer can switch the system back on.
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. 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.

WARNINGS
Do not put engine coolant in the
windshield washer fluid container. If
sprayed on the windshield, engine
coolant could make it difficult to see through
the windshield. To reduce the risk of personal injury,
make sure the engine is cool before
unscrewing the coolant pressure relief
cap. The cooling system is under pressure.
Steam and hot liquid can come out forcefully
when you loosen the cap slightly. Do not add coolant further than the
MAX mark.
Checking the Engine Coolant
When the engine is cold, check the
concentration and level of the engine coolant
at the intervals listed in the scheduled
maintenance information. See Scheduled
Maintenance (page 392).
Note: Make sure that the coolant level is
between the MIN and MAX marks on the
coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the MAX mark. Note:
If the level is at the MIN mark, below
the MIN mark, or empty, add coolant
immediately.
Maintain coolant concentration within 48%
to 50%, which equates to a freeze point
between -30°F (-34°C) and -34°F (-37°C).
Note: For best results, coolant concentration
should be tested with a refractometer such as
Robinair Coolant and Battery Refractometer
75240. We do not recommend the use of
hydrometers or coolant test strips for
measuring coolant concentrations.
Note: Automotive fluids are not
interchangeable. Do not use engine coolant,
antifreeze or windshield washer fluid outside
of its specified function and vehicle location.
Adding Engine Coolant
Note: Do not use stop leak pellets, cooling
system sealants or additives as they can cause
damage to the engine cooling or heating
systems. Your warranty may not cover these
damages.
Note: During normal vehicle operation, the
engine coolant may change color from orange
to pink or light red. As long as the engine coolant is clear and
uncontaminated, this color change does not
indicate that the engine coolant has
degraded, nor does it require that qualified
personnel drain the engine coolant, flush the
system or replace the engine coolant.
Do not mix different colors or types of coolant
in your vehicle. Mixing of engine coolants may
harm your engine
’s cooling system. The use
of an improper coolant may harm engine and
cooling system components and may void
the warranty. Use prediluted engine coolant
meeting the Ford specification. See
Capacities and Specifications (page 290).
In case of emergency, you can add a large
amount of water without engine coolant in
order to reach a vehicle service location. In
this instance, qualified personnel:
1. Must drain the cooling system.
2. Chemically clean the coolant system with
Motorcraft Premium Cooling System
Flush.
3. Refill with engine coolant as soon as possible.
Water alone, without engine coolant, can
cause engine damage from corrosion,
overheating or freezing.
241
MKS (), enUSA Maintenance

Do not use the following as a coolant
substitute:
•
Alcohol.
• Methanol.
• Brine.
• Any engine coolant mixed with alcohol
or methanol antifreeze or coolant.
Alcohol and other liquids can cause engine
damage from overheating or freezing.
Do not add extra inhibitors or additives to the
coolant. These can be harmful and
compromise the corrosion protection of the
engine coolant.
When adding coolant:
1. Unscrew the cap slowly. Any pressure will
escape as you unscrew the cap.
2. Add prediluted engine coolant meeting the Ford specification. See Capacities
and Specifications (page 290).
3. Check the coolant level in the coolant reservoir the next few times you drive your
vehicle.
4. If necessary, add enough prediluted engine coolant to bring the coolant level
to the proper level. Recycled Engine Coolant
Ford Motor Company does not recommend
the use of recycled engine coolant since a
Ford-approved recycling process is not yet
available.
Used engine coolant should be disposed of
in an appropriate manner. Follow your
community
’s regulations and standards for
recycling and disposing of automotive fluids.
Severe Climates
If you drive in extremely cold climates:
• It may be necessary to have a Ford
authorized dealer increase the coolant
concentration above 50%.
• A coolant concentration of 60% provides
improved freeze point protection. Engine
coolant concentrations above 60%
decrease the overheat protection
characteristics of the engine coolant and
may cause engine damage. If you drive in extremely hot climates:
•
It may be necessary to have a Ford
authorized dealer decrease the coolant
concentration to 40%.
• A coolant concentration of 40% provides
improved overheat protection. Engine
coolant concentrations below 40% will
decrease the freeze and corrosion
protection characteristics of the engine
coolant and may cause engine damage.
Vehicles driven year-round in non-extreme
climates should use prediluted engine
coolant for optimum cooling system and
engine protection.
What You Should Know About Fail-
Safe Cooling
If you deplete the engine coolant supply,
fail-safe cooling allows you to temporarily
drive your vehicle before you incur
incremental component damage. The
fail-safe distance depends on ambient
temperatures, vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the engine
coolant temperature gauge will move to the
red (hot) area and:
242
MKS (), enUSA Maintenance

At this time, you may notice your engine
coolant temperature gauge needle move
toward the H and the POWER REDUCED
TO LOWER TEMP message may appear in
the information display.
You may notice a reduction in vehicle speed
caused by reduced engine power. In order to
manage the engine fluid temperatures, your
vehicle may enter this mode if certain
high-temperature and high-load conditions
take place. The amount of speed reduction
depends on many factors such as vehicle
loading, towing, grade and ambient
temperature. If this occurs, there is no need
to pull off the road. You can continue to drive
your vehicle while this message is active.
The air conditioning may also cycle on and
off during severe operating conditions to
protect overheating of the engine. When the
engine coolant temperature decreases to a
normal operating temperature, the air
conditioning will turn on once again.
If the engine coolant temperature gauge
moves fully into the red (hot) area, or if the
coolant temperature warning or service
engine soon messages appear in your
information display:
1. Pull off the road as soon as safely possible and shift the transmission into
P
. 2.
Leave the engine running until the coolant
temperature gauge needle moves away
from the red (hot) area. After several
minutes, if the temperature does not
drop, follow the remaining steps.
3. Switch the engine off and wait for it to cool before checking the coolant level.
4. If the coolant level is normal, restart your
engine and continue.
5. If the coolant is low, add coolant, and restart the engine. See
Adding Engine
Coolant or How Fail-Safe Cooling
Works in this chapter for more
information.

FLUID CHECK
6F50/6F55 Transmission
(If Equipped) WARNINGS
The dipstick cap and surrounding
components may be hot, use gloves.
Use gloves when moving the air filter
assembly. Components will be hot. Note:
Automatic transmission fluid expands
when warmed. To obtain an accurate fluid
check, drive your vehicle until you warm it up,
approximately
20 mi (30 km). If you operate
your vehicle for an extended period at high
speeds, in city traffic during hot weather or
pulling a trailer, switch your vehicle off until it
reaches normal operating temperatures to
allow the fluid to cool before checking.
Depending on vehicle use, cooling times could
take up to 30 minutes or longer.
Refer to your scheduled maintenance
information for scheduled intervals for fluid
checks and changes. Your transmission does
not consume fluid. However, you should
check the fluid level if the transmission is not
working properly. For example, if the
transmission slips or shifts slowly or if you
notice some sign of a fluid leak.
1. Drive your vehicle 20 mi (30 km) or until it reaches normal operating temperature.
2. Park your vehicle on a level surface and engage the parking brake.
3. With the parking brake engaged and your
foot on the brake pedal, start the engine
and move the gearshift lever through all
of the gear ranges. Allow a minimum of
10 seconds for each gear to engage.
4. Put the gearshift lever in park (P) and leave the engine running.
