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.

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 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.
Action
Cause
Clean the grille surface in front of the radaror remove the object causing the obstruc- tion.
The surface of the radar in the grille is dirty
or obstructed in some way.
Wait a short time. It may take several
minutes for the radar to detect that there is no obstruction.
The surface of the radar in the grille is clean
but the message remains in the display.
The Pre-Collision Assist system is tempor-arily disabled. Pre-Collision Assist should
automatically reactivate a short time after the weather conditions improve.
Heavy rain, spray, snow, or fog is interfering
with the radar signals.
The Pre-Collision Assist system is tempor-arily disabled. Pre-Collision Assist should
automatically reactivate a short time after the weather conditions improve.
Swirling water, or snow or ice on the surface
of the road may interfere with the radar signals.

Action
Cause
Contact an authorized dealer to have theradar checked for proper coverage and operation.
Radar is out of alignment due to a front end
impact.
Clean the outside of the windshield in frontof the camera.
The windshield in front of the camera is
dirty or obstructed in some way.
Wait a short time. It may take several
minutes for the camera to detect that there is no obstruction.
The windshield in front of the camera is
clean but the message remains in the display.
Note: Proper system operation requires a
clear view of the road by the camera. Have
any windshield damage in the area of the
camera's field of view repaired.
Note: 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 detections. Contact an
authorized dealer to have the radar checked
for proper coverage and operation.
Note: If your vehicle detects excessive heat
at the camera or a potential misalignment
condition, a message may display in the
information display indicating temporary
sensor unavailability. This message
deactivates automatically when operational
conditions are correct. For example, when
the ambient temperature around the sensor
decreases or the sensor automatically
recalibrates successfully.
DRIVE CONTROL
Selectable Drive Modes
The system delivers a driving experience
through a suite of sophisticated electronic
vehicle systems. These systems optimize
steering, handling and powertrain
response. This provides a single location
to control multiple systems performance
settings. Changing the drive mode automatically
changes the functionality of the following
systems:
•
Electronically power-assisted steering
system adjusts steering effort and feel
based on the mode you select. See
Steering (page 256).
• Electronic stability control and traction
control maintain your vehicle control
in adverse conditions or high
performance driving. See
Stability
Control (page 216).
• Electronic throttle control enhances
the powertrain response to your inputs.
• Driveline settings optimize with shift
schedules tuned to each drive mode.
Using the System
The system automatically tailors your
vehicle configuration for each mode you
select.
The drive mode switch is in one of three
places, depending on your vehicle
configuration:

WARNING: To reduce the
risk of serious injury, when
mounting replacement tires and
wheels, you should not exceed
the maximum pressure indicated
on the sidewall of the tire to set
the beads without additional
precautions listed below. If the
beads do not seat at the
maximum pressure indicated,
re-lubricate and try again. WARNING: When inflating
the tire for mounting pressures
up to
20 psi (1.38 bar) greater
than the maximum pressure on
the tire sidewall, the following
precautions must be taken to
protect the person mounting the
tire:
• Make sure that you have the
correct tire and wheel size.
• Lubricate the tire bead and
wheel bead seat area again.
• Stand at a minimum of
12 ft
(3.66 m) away from the wheel
and tire assembly.
• Use both eye and ear
protection. WARNING: For a mounting
pressure more than
20 psi
(1.38 bar) greater than the
maximum pressure, a Ford
dealer or other tire service
professional should do the
mounting. WARNING:
Always inflate
steel carcass tires with a remote
air fill with the person inflating
standing at a minimum of
12 ft
(3.66 m) away from the wheel
and tire assembly.
Important: Remember to replace
the wheel valve stems when the
road tires are replaced on your
vehicle.
The two front tires or two rear tires
should generally be replaced as a
pair, except if the vehicle is
equipped with four wheel drive.
Vehicles equipped with four wheel
drive should have all four tires
replaced simultaneously.
Unevenly worn tires, mismatched
makes, models or brands can be
different in size, resulting in
potential damage to the four
wheel drive system.
The tire pressure sensors mounted
in the wheels are not designed to
be used in aftermarket wheels.
The use of wheels or tires not
recommended by us may affect
the operation of your tire pressure
monitoring system.
If the tire pressure monitoring
system indicator is flashing, the
system is malfunctioning. Your
replacement tire might be
incompatible with your tire
pressure monitoring system, or
some component of the system
may be damaged.
