brake pedal pulsation may be observed during ABS braking and the
brake pedal may suddenly travel a little farther as soon as ABS braking is
done and normal brake operation resumes. These are normal
characteristics of the ABS and should be no reason for concern.
Using ABS
When hard braking is required, apply continuous force on the brake
pedal. Do not pump the brake pedal since this will reduce the
effectiveness of the ABS and will increase your vehicle’s stopping
distance. The ABS will be activated immediately, allowing you to retain
steering control during hard braking and on slippery surfaces. However,
the ABS does not decrease stopping distance.
Brake assist
The brake assist system provides full braking force during panic braking
situations. It detects a rapid application of the brake pedal and uses the
ABS system to achieve maximum braking pressure. Once a panic brake
application is detected, the system will remain activated as long as the
brake pedal is pressed or ABS is engaged. The system is deactivated by
either releasing the brake pedal or coming to a complete stop. When the
system activates, noise from the ABS pump motor and brake pedal
pulsation may be observed; this is normal.
ABS warning lamp
The ABS lamp in the instrument
cluster momentarily illuminates
when the ignition is turned on. If
the light does not illuminate during
start up, remains on or flashes, the
ABS is disabled due to a malfunction and needs to be serviced.
Even when the ABS is disabled,
normal braking is still effective. If
your BRAKE warning lamp
illuminates with the parking brake
released, have your brake system
serviced immediately.
Brake over accelerator
This vehicle is equipped with a brake over accelerator feature. In the
event the accelerator pedal becomes stuck or entrapped, applying steady
and firm pressure to the brake pedal will both slow the vehicle and
reduce engine power. If you experience this condition, apply the brakes

and bring your vehicle to a safe stop. Turn the engine off, shift to P
(Park) and apply the parking brake, and then inspect the accelerator
pedal for any interferences. If none are found and the condition persists,
have your vehicle towed to the nearest authorized dealer.
Parking brake
Apply the parking brake whenever
the vehicle is parked. To set the
parking brake, press the parking
brake pedal down until the pedal
stops.
The BRAKE warning lamp in the
instrument cluster illuminates and
remains illuminated (when the
ignition is turned on) until the
parking brake is released.
WARNING:Always set the parking brake fully and make sure
that the gearshift is securely latched in P (Park).
The parking brake is not recommended to stop a moving vehicle.
However, if the normal brakes fail, the parking brake can be used to stop
your vehicle in an emergency. Since the parking brake applies only the
rear brakes, the vehicle’s stopping distance will increase greatly and the
handling of your vehicle will be adversely affected.
Press the parking brake pedal
downward again to release the
parking brake. Driving with the
parking brake on will cause the
brakes to wear out quickly and
reduce fuel economy.
Note:If the vehicle is driven with
the parking brake applied, a chime
will sound.

During trailer sway control events, the stability control light in the
instrument cluster will flash momentarily. The cluster message center
will also displayTRAILER SWAY REDUCE SPEED. In some cases
when trailer sway is detected, the vehicle speed is too high and may be
at or above a speed at which trailer sway will grow continuously. This
may cause the system to activate multiple times, causing a gradual
reduction in speed.
Disabling trailer sway control
Trailer sway control can be disabled during any key cycle. To disable
trailer sway control, refer to theMessage centerin theInstrument
Clusterchapter. Note that regardless of chosen enable state, trailer sway
control will be re-enabled each new key cycle.
WARNING:Turning off trailer sway control increases the risk of
loss of vehicle control, serious injury, or death. Ford does not
recommend disabling this feature except in situations where speed
reduction may be detrimental (e.g., hill climbing), the driver has
significant trailer towing experience, and can control trailer sway and
maintain safe operation.
STEERING
3.5L EcoBoost™ engine (if equipped):Your vehicle is equipped with
an Electric Power Steering (EPS) system. There is no fluid reservoir to
check or fill.
If your vehicle loses electrical power while you are driving (or if the
ignition is turned off), you can steer the vehicle manually, but it takes
more effort. Extreme continuous steering may increase the effort it takes
for you to steer. This occurs to prevent internal overheating and
permanent damage to your steering system. If this should occur, you will
neither lose the ability to steer the vehicle manually nor will it cause
permanent damage. Typical steering and driving maneuvers will allow the
system to cool and steering assist will return to normal.
The EPS system has diagnostic checks that continuously monitor the
EPS system to ensure proper operation. When a system error is
detected, the following message SERVICE POWER STEERING, SERVICE
POWER STEERING NOW or POWER STEERING ASSIST FAULT may
display in the message center, refer to theMessage centerin the
Instrument Clusterchapter for more information.

If the steering wanders or pulls equipped with either EPS or hydraulic
steering system, check for:
•an improperly inflated tire
•uneven tire wear
•loose or worn suspension components
•loose or worn steering components
•improper vehicle alignment
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.
WARNING:Obtain immediate service if a system error is
detected. You may not notice any difference in the feel of your
steering, but a serious condition may exist. Failure to do so may result
in loss of steering control.
BRAKE-SHIFT INTERLOCK
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved from P (Park) when the ignition is
in the on position unless the brake pedal is applied. If you cannot move
the gearshift lever out of P (Park) when the ignition is on and the brake
pedal applied, it is possible that a fuse has blown or the vehicle’s brake
lamps are not operating properly. Refer toFuses and relaysin the
Roadside Emergencieschapter.
If the fuse is not blown and the brake lamps are working properly, you
will need to have your vehicle towed to an authorized dealer.
WARNING:Do not drive your vehicle until you verify that the
brake lamps are working.
WARNING:Always set the parking brake fully and make sure
the gearshift lever is latched in P (Park). Switch the ignition to
off and remove the key whenever you leave your vehicle.
WARNING:If the parking brake is fully released, but the brake
warning lamp remains illuminated, the brakes may not be
working properly. See your authorized dealer.

AUTOMATIC TRANSMISSION OPERATION
Automatic transmission adaptive learning
Your transmission is equipped with an adaptive learning strategy found in
the vehicle computer. This feature is designed to increase durability and
provide consistent shift feel over the life of the vehicle. A new vehicle or
transmission may have firm and/or soft shifts. This operation is
considered normal and will not affect function or durability of the
transmission. Over time, the adaptive learning process will fully update
transmission operation. Additionally, whenever the battery is
disconnected or a new battery installed, the strategy must be relearned.
Understanding the gearshift positions of the 6–speed automatic
transmission
Your vehicle has been designed to improve fuel economy by reducing
fuel usage while coasting or decelerating. When you take your foot off
the accelerator pedal and the vehicle begins to slow down, the torque
converter clutch locks up and aggressively shuts off fuel flow to the
engine while decelerating. This fuel economy benefit may be perceived
as a light to medium braking sensation when removing your foot from
the accelerator pedal.
P (Park)
This position locks the transmission
and prevents the front wheels from
turning.
To put your vehicle in gear:
•Press the brake pedal
•Move the gearshift lever into the
desired gear
To put your vehicle in P (Park):
•Come to a complete stop
•Move the gearshift lever and securely latch it in P (Park)
WARNING:Always set the parking brake fully and make sure
the gearshift is latched in P (Park). Switch the ignition off and
remove the key whenever you leave your vehicle.
R (Reverse)
With the gearshift lever in R (Reverse), the vehicle will move backward.
Always come to a complete stop before shifting into and out of R (Reverse).

WARNING:Certain add-on devices such as large trailer hitches,
bike or surfboard racks and any device that may block the
normal detection zone of the RSS system may create false beeps.
The RSS detects obstacles up to six
feet (two meters) from the rear
bumper with a decreased coverage
area at the outer corners of the
bumper, (refer to the figures for
approximate zone coverage areas).
As you move closer to the obstacle,
the rate of the tone increases. When
the obstacle is less than 10 inches
(25.0 cm) away, the tone will sound
continuously. If the RSS detects a
stationary or receding object further
than 10 inches (25.0 cm) from the
side of the vehicle, the tone will
sound for only three seconds. Once
the system detects an object
approaching, the tone will sound
again.
While receiving a warning the radio
volume will be reduced to a
predetermined level. After the
warning goes away, the radio will return to the previous value.
The RSS automatically turns on when the gearshift lever is placed in R
(Reverse) and the ignition is on. A control in the message center allows
the driver to disable the system, refer toMessage centerin the
Instrument Clusterchapter for more information.
Note:If the system cannot be turned off, refer toMyKeyin theLocks
and Securitychapter for more information.
Keep the RSS sensors (located on the rear bumper/fascia) free
from snow, ice and large accumulations of dirt (do not clean the
sensors with sharp objects). If the sensors are covered, it will
affect the accuracy of the RSS.
If your vehicle sustains damage to the rear bumper/fascia, leaving
it misaligned or bent, the sensing zone may be altered causing
inaccurate measurement of obstacles or false alarms.

CTA and reverse sensing system (RSS) interaction
CTA works along with the reverse sensing system (RSS) (if equipped).
Become familiar with the warning tones of both systems.
BLISand/or CTA on/off and disable operation
The BLISand/or the CTA can be turned off via the message center. If
either the BLISand/or the CTA is turned off, the systems will
automatically turn back on at the next ignition key cycle. When either
the BLISand/or the CTA is turned off, the message center displays
BLIND SPOT SYS OFF and/or CTA SYSTEM OFF. When the BLIS
and/or the CTA system is off, the driver will not receive alerts. Refer to
Message centerin theInstrument Clusterchapter.
Note:If the system cannot be turned off, refer toMyKeyin theLocks
and Securitychapter for more information.
The BLISand/or the CTA can be disabled permanently even after an
ignition key cycle. This must be done by your authorized dealer.Note:
Once either of the systems are disabled, enabling must also be performed
at the dealership. When disabled, the message center will display BLIND
SPOT DISABLED and/or CTA DISABLED.
BLISand/or CTA fault operation
If the BLISand/or CTA senses a fault on either the left or right sensor,
the BLISalert indicator will go on and remain on and the message center
will display BLIND SPOT SYSTEM FAULT or CROSS TRAFFIC SYSTEM
FAULT. For faults that may cause the associated left or right alert indicator
not to illuminate, only the message center faults will occur.
Blocked sensor
An extreme build-up of materials on
the quarter panel fascias such as
mud or snow can cause degraded
performance of the BLIS. Also,
heavy rain can cause the same
effect. The BLIScan detect this
degraded performance and issue a
blocked warning to the driver via
the message center. If a condition is determined by the system, the
message center displays BLIND SPOT NOT AVAILABLE or CROSS
TRAFFIC NOT AVAILABLE warning and the appropriate left and/or right
exterior mirror alert indicator will illuminate. The message center
warning may be cleared by the driver but the exterior mirror alert
indicator will remain illuminated.

WARNING:Just prior to the system recognizing a blocked
condition and alerting the driver, the number of missed objects
will increase. To help avoid injuries, NEVER use the BLISas a
replacement for using the side and rear view mirrors and looking over
your shoulder before changing lanes. BLISis not a replacement for
careful driving and only an assist.
Once the blockage is removed, the system will require some driving time
and detection of at least two vehicle objects prior to resetting or the
driver can cycle the ignition key. If, however, blockage is still present
after the key cycle, the system will sense again that it is blocked after
driving in traffic.
The following table lists possible causes and actions for this message
being displayed:
The surface of the radar is dirty or
obstructed in some wayClean the fascia area in front of
the radar, either side, or remove
obstruction.
The surface of the radar is not
dirty or obstructedDrive normally in traffic for a few
minutes to allow the radar to
detect that it is no longer blocked.
Note:The vehicle must be in D
(Drive) and a few vehicles must
pass so that the BLIScan clear a
blocked state.
Heavy rainfall or heavy snowfall is
interfering with the radar signalsNo action required by the driver.
The system will automatically reset
to an unblocked state once the
rainfall/snowfall rate decreases or
stops. Do not use BLISand/or
CTA in heavy rainfall or heavy
snowfall.
Due to the nature of radar technology, it is possible to get a blockage
warning and not be blocked. This is rare and known as a false blockage
warning. A false blocked condition will either self clear or clear after a
key cycle.

If your vehicle gets stuck
If your vehicle gets stuck in mud or snow it may be rocked out by
shifting between forward and reverse gears, stopping between shifts, in a
steady pattern. Press lightly on the accelerator in each gear.
Your vehicle is equipped with traction control. It may be beneficial to
disengage the traction control system while attempting to rock the
vehicle.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a few minutes or damage
to the transmission and tires may occur or the engine may
overheat.
WARNING:Always set the parking brake fully and make sure
the gearshift is latched in P (Park). Switch the ignition off and
remove the key whenever you leave your vehicle.
WARNING:If the parking brake is fully released, but the brake
warning lamp remains illuminated, the brakes may not be
working properly. See your authorized dealer.
WARNING:Do not spin the wheels at over 35 mph (56 km/h).
The tires may fail and injure a passenger or bystander.
Emergency maneuvers
•In an unavoidable emergency situation where a sudden sharp turn
must be made, remember to avoid “over-driving” your vehicle (i.e.,
turn the steering wheel only as rapidly and as far as required to avoid
the emergency). Excessive steering will result in less vehicle control,
not more. Additionally, smooth variations of the accelerator and/or
brake pedal pressure should be utilized if changes in vehicle speed are
called for. Avoid abrupt 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) there will be a change in the way the vehicle
responds to a maneuver (steering, acceleration or braking). Again,
avoid these abrupt inputs.
AWD systems (if equipped)
AWD 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.
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 spinning the wheels.
When driving at slow speeds in deep sand under high outside
temperatures, use a low gear when possible. Lower 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 (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.
If the engine, transmission, AWD system components or axles are
submerged in water, their fluids should be checked and changed, if
necessary.
