PRINCIPLE OF OPERATION
WARNINGS
Vehicle modifications involving
braking system, aftermarket roof
racks, suspension, steering system,
tire construction and wheel and tire size
may change the handling characteristics
of your vehicle and may adversely affect
the performance of the electronic stability
control system. In addition, installing any
stereo loudspeakers may interfere with
and adversely affect the electronic stability
control 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 electronic stability
control sensors. Reducing the
effectiveness of the electronic stability
control system could lead to an increased
risk of loss of vehicle control, vehicle
rollover, personal injury and death. 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
electronic stability control 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 electronic
stability control system activates, SLOW
DOWN. The system automatically turns on each
time you switch the ignition on. If a fault occurs in either the stability
control or the traction control system, you
may experience the following conditions:
•
The stability and traction control light
illuminates steadily.
• The stability control and traction
control systems do not enhance your
vehicle's ability to maintain traction of
the wheels.
If a driving condition activates either the
stability control or the traction control
system you may experience the following
conditions:
• The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
• A vibration in the brake pedal.
• The brake pedal is stiffer than usual.
• If the driving condition is severe and
your foot is not on the brake, the brake
pedal may move as the system applies
higher brake force.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
The system enhances your vehicle ’s ability
to prevent skids or lateral slides by
applying brakes to one or more of the
wheels individually and, if necessary,
reducing engine power.
Traction Control
The system enhances your vehicle ’s ability
to maintain traction of the wheels by
detecting and controlling wheel spin. See
Using Traction Control (page 148).

PRINCIPLE OF OPERATION
WARNINGS
To help avoid personal injury, please
read and understand the limitations
of the system as contained in this
section. Sensing is only an aid for some
(generally large and fixed) objects when
moving on a flat surface at parking speeds.
Certain objects with surfaces that absorb
ultrasonic waves, surrounding vehicle's
parking aid systems, traffic control
systems, fluorescent lamps, inclement
weather, air brakes, and external motors
and fans may also affect the function of
the sensing system; this may include
reduced performance or a false activation. To help avoid personal injury, always
use caution when in reverse (R) and
when using the sensing system.
This system is not designed to
prevent contact with small or moving
objects. The system is designed to
provide a warning to assist the driver in
detecting large stationary objects to avoid
damaging your vehicle. The system may
not detect smaller objects, particularly
those close to the ground. 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 system, may
create false beeps. Note:
Keep the sensors, located on the
bumper or fascia, free from snow, ice and
large accumulations of dirt. If the sensors
are covered, the system ’s accuracy can be
affected. Do not clean the sensors with
sharp objects.
Note: If your vehicle sustains damage to
the bumper or fascia, leaving it misaligned
or bent, the sensing zone may be altered
causing inaccurate measurement of
obstacles or false alarms. Note:
The sensing system cannot be turned
off when a MyKey is present. See Principle
of Operation (page 54).
Note: If you attach certain add-on devices
such as a trailer or bike rack, the rear sensing
system may detect that add-on device and
therefore provide warnings. It is suggested
that you disable the rear sensing system
when you attach an add-on device to your
vehicle to prevent these warnings.
The sensing system warns the driver of
obstacles within a certain range of your
vehicle. The system turns on automatically
whenever you switch the ignition on. You can turn the system on or
off by pressing the parking aid
button. If your vehicle does not
have a parking aid button, the system can
be switched off through the information
display menu or from the pop-up message
that appears once you shift the
transmission into reverse (R). See General
Information
(page 91).
If a fault is present in the system, a warning
message appears in the information
display. See
Information Messages
(page 95).
REAR PARKING AID
The rear parking aid sensors automatically
turn on when you shift into reverse (R).
As your vehicle moves closer to the
obstacle, the rate of the audible warning
increases. When the obstacle is less than
12 in (30 cm)
away, the warning sounds
continuously. If the system detects an
object farther than
12 in (30 cm) from the
corners of the bumper, the tone sounds for
only three seconds. If the system detects
an approaching object the warning sounds
again.

ACTIVE PARK ASSIST
Parallel Parking, Perpendicular
Parking, Parallel Park Out Assist
WARNINGS
You must remain in your vehicle
when the system turns on. At all
times, you are responsible for
controlling your vehicle, supervising the
system and intervening, if required. Failure
to take care may result in the loss of
control of your vehicle, serious personal
injury or death. The sensors may not detect objects
in heavy rain or other conditions that
cause interference.
Active park assist does not apply the
brakes under any circumstances.
The system is designed to aid the
driver. It is not intended to replace
your attention and judgment. You are
still responsible to drive with due care and
attention. Note:
The Blind Spot Information System
does not detect traffic alongside or behind
your vehicle during an active park assist
maneuver.
The system detects an available parallel
or perpendicular parking space and
automatically steers your vehicle into the
space (hands-free) while you control the
accelerator, gearshift and brakes. The
system visually and audibly guides you to
park your vehicle.
If you are uncomfortable with the proximity
to any vehicle or object, you may choose
to override the system by grabbing the
steering wheel or pushing the active park
assist button. Parallel Park Out Assist automatically
steers your vehicle out of a parallel parking
space (hands-free) while you control the
accelerator, gearshift and brakes. The
system visually and audibly guides you to
enter traffic.
The system may not correctly operate in
any of the following conditions:
•
You use a spare tire or a tire
significantly worn more than the other
tires.
• One or more tires are improperly
inflated.
• You try to park on a tight curve.
• Something passes between the front
bumper and the parking space (a
pedestrian or cyclist).
• The edge of the neighboring parked
vehicle is high off the ground (for
example, a bus, tow truck or flatbed
truck).
• The weather conditions are poor
(heavy rain, snow, fog, etc).
Note: Keep the sensors, located on the
bumper or fascia, free from snow, ice and
large accumulations of dirt. Covered sensors
can affect the system's accuracy. Do not
clean the sensors with sharp objects.
Note: The sensors may not detect objects
with surfaces that absorb ultrasonic waves
or cause ultrasonic interference (motorcycle
exhaust, truck air brakes or horns).
Do not use the system if:
• You have attached a foreign object (for
example, a bike rack or trailer) close to
the sensors on the front or rear of your
vehicle.
• You have attached an overhanging
object (for example, a surfboard) to
the roof.

How Temperature Affects Your Tire
Pressure
The tire pressure monitoring system
monitors tire pressure in each pneumatic
tire. While driving in a normal manner, a
typical passenger tire inflation pressure
may increase about 2
–4 psi (14– 28 kPa)
from a cold start situation. If the vehicle is
stationary overnight with the outside
temperature significantly lower than the
daytime temperature, the tire pressure may
decrease about 3 psi (21 kPa) for a drop of
30°F (17°C) in ambient temperature. This
lower pressure value may be detected by
the tire pressure monitoring system as
being significantly lower than the
recommended inflation pressure and
activate the system warning light for low
tire pressure. If the low tire pressure
warning light is on, visually check each tire
to verify that no tire is flat. If one or more
tires are flat, repair as necessary. Check
the air pressure in the road tires. If any tire
is under-inflated, carefully drive the vehicle
to the nearest location where air can be
added to the tires. Inflate all the tires to
the recommended inflation pressure.
CHANGING A ROAD WHEEL WARNINGS
The use of tire sealant may damage
your tire pressure monitoring system
and should only be used in roadside
emergencies. If you must use a sealant, the
Ford Tire Mobility Kit sealant should be
used. The tire pressure monitoring system
sensor and valve stem on the wheel must
be replaced by an authorized dealer after
use of the sealant. If the tire pressure monitor sensor
becomes damaged, it will no longer
function. See
Tire Pressure
Monitoring System (page 261). Note:
The tire pressure monitoring system
indicator light will illuminate when the spare
tire is in use. To restore the full function of
the monitoring system, all road wheels
equipped with tire pressure monitoring
sensors must be mounted on this vehicle.
If you get a flat tire while driving, do not
apply the brake heavily. Instead, gradually
decrease your speed. Hold the steering
wheel firmly and slowly move to a safe
place on the side of the road.
Have a flat serviced by an authorized
dealer in order to prevent damage to the
system sensors
See Tire Pressure
Monitoring System (page 261). Replace
the spare tire with a road tire as soon as
possible. During repairing or replacing of
the flat tire, have the authorized dealer
inspect the system sensor for damage.
Dissimilar Spare Wheel and Tire
Assembly 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 wheel and
tire, 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 wheel and tire assembly 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 wheel and tire assembly
is defined as a spare wheel and tire
assembly that is different in brand, size or
appearance from the road tires and wheels
and can be one of three types:
