ignition FORD SUPER DUTY 2017 4.G Repair Manual

PRINCIPLE OF OPERATION
The traction control system helps avoid
drive wheel spin and loss of traction.
If your vehicle begins to slide, the system
applies the brakes to individual wheels
and, when needed, reduces engine power
at the same time. If the wheels spin when
accelerating on slippery or loose surfaces,
the system reduces engine power in order
to increase traction.
USING TRACTION CONTROL
WARNING
The stability and traction control
light illuminates steadily if the
system detects a failure. Make sure
you did not manually disable the traction
control system using the information
display controls or the switch. If the
stability control and traction control light
is still illuminating steadily, have the
system serviced by an authorized dealer
immediately. Operating your vehicle with
the traction control disabled could lead to
an increased risk of loss of vehicle control,
vehicle rollover, personal injury and death. The system automatically turns on each
time you switch the ignition on.
If your vehicle is stuck in mud or snow,
switching traction control off may be
beneficial as this allows the wheels to spin.
Note:
When you switch traction control off,
stability control remains fully active.
Note: For additional information on the
traction and stability control systems. See
Using Stability Control (page 227).
Switching the System Off
When you switch the system off or on, a
message appears in the information
display showing system status. Use the traction and stability control
switch on the instrument panel to switch
the system off or on.
The switch illuminates when traction
control is off.
When you place your vehicle into
four-wheel drive low mode the traction
control disables. Traction control resumes
full operation when you put your vehicle
back into two-wheel drive mode.
System Indicator Lights and
Messages
The stability and traction control
light:
• Temporarily illuminates on engine
start-up.
• Flashes when a driving condition
activates either of the systems.
• Illuminates if a problem occurs in either
of the systems. The stability and traction control
off light temporarily illuminates
on engine start-up and stays on
when you switch the traction control
system off.

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.
• The Adaptive Steering system (if
equipped) automatically changes the
steering function to a fixed steering
ratio. See Steering (page 256).
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.
226
Super Duty (TFE) Canada/United States of America, enUSA, First Printing Stability Control

Roll Stability Control
The system enhances your vehicle
’s ability
to prevent rollovers by detecting your
vehicle ’s roll motion and the rate at which
it changes by applying the brakes to one
or more wheels individually.
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 225). Vehicle without stability control

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 61).
Note: If your vehicle is equipped with a
trailer tow package and a trailer is
connected to your vehicle, the rear sensing
system disables and you cannot switch the
system on through the information display.
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.
When receiving a detection warning, the
radio volume reduces to a predetermined
level. After the warning goes away, the
radio volume returns to the previous level. 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 111).
If a fault is present in the system, a warning
message appears in the information
display and you cannot switch the system
on through the pop-up message. See
Information Messages
(page 128).
REAR PARKING AID
The rear sensors are only active when the
transmission is in 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 a

Switching Cruise Control Off
Press and release OFF when the system is
in stand by mode or switch the ignition off.
Note: You erase the set speed when you
switch the system off.
USING ADAPTIVE CRUISE
CONTROL
(If Equipped) WARNINGS
Always pay close attention to
changing road conditions when using
adaptive cruise control. The system
does not replace attentive driving. Failing
to pay attention to the road may result in
a crash, serious injury or death. Adaptive cruise control is not a crash
warning or avoidance system.
Adaptive cruise control does not
detect stationary or slow moving
vehicles below
6 mph (10 km/h).
Adaptive cruise control does not
detect pedestrians or objects in the
road.
Adaptive cruise control does not
detect oncoming vehicles in the
same lane.
Do not use adaptive cruise control
on winding roads, in heavy traffic or
when the road surface is slippery.
This could result in loss of vehicle control,
serious injury or death. Do not use adaptive cruise control
with a snow plow blade installed. WARNINGS
Do not use adaptive cruise control
when towing a trailer that has trailer
brakes. The auto-brake component
of the adaptive cruise control system does
not operate the trailer brakes. Using
adaptive cruise control when towing a
trailer that has trailer brakes may result in
the loss of vehicle control, which could
result in serious injury. Do not use tire sizes other than those
recommended because this can
affect the normal operation of the
system. Failure to do so may result in a loss
of vehicle control, which could result in
serious injury. Note:
It is your responsibility to stay alert,
drive safely and control the vehicle at all
times.
The system adjusts your speed to maintain
a proper distance between you and the
vehicle in front of you in the same lane. You
can select from one of four gap settings. The controls for using your cruise control
are located on the steering wheel.
Switching the System On
Press and release
ON.

Switching the System Off
Note:
The set speed memory erases when
you switch off the system.
Press and release OFF or switch off the
ignition.
Detection Issues WARNING
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. The radar sensor has a limited field of
vision. 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. Stay alert and take action
when necessary.
244
Super Duty (TFE) Canada/United States of America, enUSA, First Printing Cruise Control
(If Equipped)E71621

The system uses radar sensors that are
located inside the tail lamp on each side
of your vehicle. Any dirt, mud and snow in
front of the sensors or driving in heavy rain
can cause system degradation. Also, other
types of obstructions in front of the sensor
can cause system degradation. This is
referred to as a
‘blocked ’ condition.
Note: Do not apply bumper stickers and/or
repair compound to these areas, this can
cause degraded system performance.
If the system detects a degraded
performance condition, a message warning
appears in the display screen. The alert
indicators remain ON and the system will
no longer provides any warnings. You can
clear the warning but the alert indicators
remain illuminated.
A "blocked" condition can be cleared in
two ways:
• After the blockage in front of the
sensors is removed or the
rainfall/snowfall rate decreases or
stops, drive for a few minutes in traffic
to allow the sensors to detect passing
vehicles.
• By cycling the ignition from ON to OFF
and then back ON.
Note: If your vehicle has a tow bar with a
factory equipped trailer tow module and it
is towing a trailer, the sensors will
automatically turn the Blind Spot
Information System off. If your vehicle has
a tow bar but no factory equipped trailer
tow module, it is recommended to turn the
Blind Spot Information System off
manually. Operating the Blind Spot
Information System without the Blind Spot
Trailer Tow package and a trailer attached
will cause poor system performance. Blind Spot Information System
with Trailer Tow (If Equipped)
The Blind Spot Information System with
Trailer Tow is designed to aid you in
detecting vehicles that may have entered
the detection area zone (A). The detection
area is on both sides of your vehicle and
trailer, extending rearward from the
exterior mirrors to the end of your trailer.
When a trailer is attached and the
customer has set up a Blind Spot Trailer,
the Blind Spot Information System with
Trailer Tow becomes active when driving
forward above
6 mph (10 km/h). See
Trailer Reversing Aids (page 269).
The Blind Spot Information System with
Trailer Tow can be turned off in the
instrument cluster. If the Blind Spot
Information System is turned off, then the
Blind Spot Information System with Trailer
Tow automatically turns off.

System Operation
If you select a trailer in the display screen
prior to connecting the trailer, the system
will load that configuration and the
information cluster displays a message
when the trailer is connected. A second
message appears stating Cross Traffic
Alert has been turned off; the Blind Spot
Information System with Trailer Tow still
functions normally when driving forward.
If no trailer has been set up and a trailer is
connected, the instrument cluster provides
a message indicating a trailer is connected
followed by a message asking to select a
trailer from the existing list of trailers or to
add a trailer. In order for the Blind Spot
Information System with Trailer Tow to
function, an existing trailer must be
selected or a new trailer must be added. If
the request is ignored or if you exit the
screen, a message appears prompting you
that the system has been turned off due
to a trailer connect. This message may not
appear until your vehicle speed reaches
22 mph (35 km/h).
The Blind Spot Information System with
Trailer Tow activates when driving forward
for that particular trailer set up. If the
ignition is cycled, the Blind Spot
Information System with Trailer Tow
continues to function using the last trailer
selected.
Trailer Considerations
The Blind Spot Information System with
Trailer Tow is designed to work with any
trailer whose front width is
8.5 ft (2.6 m)
or less and total length from the trailer
hitch ball to the rear of the trailer is
30 ft
(9 m) or less. Different trailers may cause
a slight change in performance as outlined
below. Large box trailers may cause false alerts
to trigger when driving next to buildings or
near parking cars. A false alert may also
occur while making a 90-degree turn.
Trailers that are
8.5 ft (2.6 m) wide at the
front and have a total length greater than
20 ft (6 m)
may have delayed alerts from
passing vehicles when the vehicle is
passing at high speed.
A box trailer whose front width is
8.5 ft
(2.6 m) may cause early alerts when you
are over taking a vehicle.
When towing a clam shell or V-Nose box
trailer with a front width of
8.5 ft (2.6 m),
delayed alerts on merging vehicles that are
traveling the same speed as your vehicle
may occur.
System Errors
If the system senses a problem with the
left or right sensor, the telltale illuminates
and a message appears in the display
screen. See
Information Messages
(page 128).
Switching the System Off and On
You can temporarily switch the Blind Spot
Information System off in the display
screen. See
General Information (page
111). When the Blind Spot Information
System switches off, you do not receive
alerts and the display screen shows a
system off message. The telltale in the
cluster also illuminates. When you switch
the Blind Spot Information System on or
off, the alert indicators flash twice.
Note: The Blind Spot Information System
remembers the last selected on or off
setting.
You can also have the Blind Spot
Information System switched off
permanently at an authorized dealer. Once
switched off permanently, the system can
only be switched back on at an authorized
dealer.

System Limitations
Cross Traffic Alert has its limitations;
situations such as severe weather
conditions or debris build-up on the sensor
area may limit vehicle detection.
The following are other situations that may
limit the Cross Traffic Alert performance:
•
Adjacently parked vehicles or objects
obstructing the sensors.
• Approaching vehicles passing at
speeds greater than 37 mph
(60 km/h).
• Driving in reverse faster than
7 mph
(12 km/h).
• Backing out of an angled parking spot.
False Alerts
Note: If your vehicle has a tow bar with a
factory equipped trailer tow module and it
is towing a trailer, the sensors will
automatically turn the Cross Traffic Alert
off. If your vehicle has a tow bar but no
factory equipped trailer tow module, it is
recommended to turn the Cross Traffic Alert
off manually. Operating Cross Traffic Alert
with a trailer attached will cause poor Cross
Traffic Alert performance.
There may be certain instances when there
is a false alert by the Cross Traffic Alert
system that illuminates the alert indicator
with no vehicle in the coverage zone. Some
amount of false alerts are normal; they are
temporary and self-correct.
System Errors
If Cross Traffic Alert senses a problem with
the left or right sensor a message appears
in the display screen. See
Information
Messages (page 128). Switching the System Off and On
Note:
The Cross Traffic Alert switches on
whenever the ignition is switched on and
ready to provide appropriate alerts when
the transmission is in reverse (R). Cross
Traffic Alert will not remember the last
selected on or off setting.
You can temporarily switch Cross Traffic
Alert off in the information display. See
General Information
(page 111). When
you switch Cross Traffic Alert off, you do
not receive alerts and the display screen
shows a system off message.
You can also have Cross Traffic Alert
switched off permanently at an authorized
dealer. Once switched off permanently,
the system can only be switched back on
at an authorized dealer.
STEERING
Power Steering
To help prevent damage to the power
steering system:
• Never hold the steering wheel at its
furthest turning points (until it stops)
for more than three seconds when the
engine is running.
• Do not operate the vehicle with a low
power steering pump fluid level (below
the MIN mark on the reservoir).
• Some noise is normal during operation.
If excessive, check for low power
steering pump fluid level before
seeking service by your dealer.
• Heavy or uneven efforts may be caused
by low power steering fluid. Check for
low power steering pump fluid level
before seeking service by your dealer.
• Do not fill the power steering pump
reservoir above the MAX mark on the
reservoir, as this may result in leaks
from the reservoir.
256
Super Duty (TFE) Canada/United States of America, enUSA, First Printing Driving Aids

When backing down a ramp during boat
launching or retrieval:
•
Do not allow the static water level to
rise above the bottom edge of the rear
bumper.
• Do not allow waves to break higher
than 6 in (15 cm) above the bottom
edge of the rear bumper.
Exceeding these limits may allow water to
enter vehicle components:
• Causing internal damage to the
components.
• Affecting driveability, emissions, and
reliability.
Replace the rear axle lubricant anytime
the rear axle has been submerged in water.
Water may have contaminated the rear
axle lubricant, which is not normally
checked or changed unless a leak is
suspected or other axle repair is required.
