Detection Issues
WARNINGS
On rare occasions, detection issues
can occur due to the road
infrastructures, for example bridges,
tunnels and safety barriers. In these cases,
the system may brake late or
unexpectedly. At all times, you are
responsible for controlling your vehicle,
supervising the system and intervening, if
required. If the system malfunctions, have your
vehicle checked as soon as possible.
The radar sensor has a limited field of view.
It may not detect vehicles at all or detect
a vehicle later than expected in some
situations. The lead vehicle graphic does
not illuminate if the system does not
detect a vehicle in front of you.
Detection issues can occur:
When driving on a different line
than the vehicle in front.
A
With vehicles that edge into your
lane. The system can only detect
these vehicles once they move
fully into your lane.
B
There may be issues with the
detection of vehicles in front
when driving into and coming out
of a bend or curve in the road.
C
In these cases, the system may brake late
or unexpectedly. You should stay alert and
take action when necessary.
If something hits the front end of your
vehicle or damage occurs, the
radar-sensing zone may change. This could
cause missed or false vehicle detection.

System Not Available
The system may not turn on if there is:
•
A blocked sensor.
• High brake temperature.
• A failure in the system or a related
system.
• The system does not detect a lead
vehicle after you stop, or driving at low
speeds. Blocked Sensor Note:
You cannot see the sensor. It is
behind a fascia panel.
A message displays if something obstructs
the radar signals from the sensor. The
sensor is in the lower grille. The system
cannot detect a vehicle ahead and does
not function when something blocks the
sensor.
Possible Causes and Actions for This Message Displaying: Action
Cause
Clean the grille surface in front of the radar
or remove the object causing the obstruc-
tion.
The surface of the radar is dirty or
obstructed.
Wait a short time. It may take several
minutes for the radar to detect that it is free
from obstruction.
The surface of the radar is clean but the
message remains in the display.
Do not use the system in these conditions
because it may not detect any vehicles
ahead.
Heavy rain or snow is interfering with the
radar signals.
Do not use the system in these conditions
because it may not detect any vehicles
ahead.
Water, snow or ice on the surface of the
road may interfere with the radar signals.
Wait a short time or switch to normal cruise
control.
You are in a desert or remote area with no
other vehicles and no roadside objects.
Due to the nature of radar technology, it is possible to get a blockage warning with no
actual block. This happens, for example, when driving in sparse rural or desert
environments. A false blocked condition either self clears, or clears after you restart your
vehicle.

Alert: When activated, a red warning light
flashes, an audible warning chime sounds
and a warning message shows in the
information display.
Brake Support
: Assists the driver in
reducing collision speed by preparing the
brake system for rapid braking. Brake
support does not automatically activate
the brakes, but if the brake pedal is pressed
even lightly by the driver, brake support
could add additional braking up to full
force.
Active Braking
: Active braking may
activate if the system determines that a
collision is imminent. The system may help
the driver reduce impact damage or avoid
the crash completely.
Note: If you perceive Pre-Collision Assist
alerts as being too frequent or disturbing,
then you can reduce the alert sensitivity,
though the manufacturer recommends
using the highest sensitivity setting where
possible. Setting lower sensitivity would
lead to fewer and later system warnings.
Adjusting the Pre-Collision Assist
Settings
You can adjust the Pre-Collision Assist
settings by using the information display
control. See General Information (page
96
).
If required, you can switch active braking
off using the information display control.
See
General Information (page 96).
Note: Active braking automatically turns
on every time you switch the ignition on. Blocked Sensors
If a message regarding a blocked sensor
or camera appears in the information
display, the radar signals or camera images
are obstructed. The radar sensor is located
behind a fascia cover near the driver side
of the lower grille. With an obstructed
radar, the Pre-Collision Assist system does
not function and cannot detect a vehicle
ahead. With the front camera obstructed,
the Pre-Collision Assist system does not
respond to pedestrians or stationary
vehicles and the system performance on
moving vehicles reduces. The following
table lists possible causes and actions for
when this message displays.

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
Do not use tire sealants as they may
damage the tire pressure monitoring
system.
If the tire pressure monitor sensor
becomes damaged it may not
function.
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 the 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
tire pressure monitoring system sensors.
See
Tire Pressure Monitoring System
(page 300). Replace the spare tire with a
road tire as soon as possible. During
repairing or replacing of the flat tire, have
an authorized dealer inspect the tire
pressure monitoring 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.
