2017 FORD SUPER DUTY warning light

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.

PRINCIPLE OF OPERATION
WARNINGS
Hill descent control cannot control
descent in all surface conditions and
circumstances, such as ice or
extremely steep grades. Hill descent
control is a driver assist system and cannot
substitute for good judgment by the driver.
Failure to do so may result in loss of vehicle
control, crash or serious injury. Hill descent control does not provide
hill hold at zero miles per hour (0
kilometers per hour). When stopped,
the parking brake must be applied or the
vehicle must be placed in P (Park) or it
may roll away. Hill descent control allows the driver to set
and maintain vehicle speed while
descending steep grades in various surface
conditions.
Hill descent control can maintain vehicle
speeds on downhill grades between 2 mph
(3 km/h) and 12 mph (20 km/h). Above 20
mph (32 km/h), the system remains
armed, but descent speed cannot be set
or maintained.
Hill descent control requires a cooling
down interval after a period of sustained
use. The amount of time that the feature
can remain active before cooling varies
with conditions. The system will provide a
warning in the message center and a chime
will sound when the system is about to
disengage for cooling. At this time,
manually apply the brakes as needed to
maintain descent speed. USING HILL DESCENT
CONTROL Press and release the hill
descent button located on the
instrument panel. A light in the
cluster will illuminate and a chime will
sound when this feature is activated.
To increase descent speed, press the
accelerator pedal until the desired speed
is reached. To decrease descent speed,
press the brake pedal until the desired
speed is reached.
Whether accelerating or decelerating, once
the desired descent speed is reached,
remove your feet from the pedals and the
chosen vehicle speed will be maintained.
Note: Noise from the ABS pump motor may
be observed during hill descent control
operation. This is a normal characteristic of
the ABS and should be no reason for
concern.
Hill descent modes
• At speeds below 20 mph (32 km/h):
When the Hill Descent Control switch
is pressed and Hill Descent Control is
active, the Hill Descent Control telltale
will flash.
• At speeds below 20 mph (32 km/h):
When the Hill Descent Control switch
is pressed and conditions are not
correct for hill descent activation, the
Hill Descent Control system will be
enabled, the Hill Descent Control
telltale will be solid and a message will
display in the information display.
• At speeds above 20 mph (32 km/h):
When the Hill Descent Control switch
is pressed, the Hill Descent Control
system will be enabled, the telltale in
the cluster will not be illuminated and
a message will be displayed in the
information display.

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.
The information display shows
the grey indicator light.

shows.
Setting a Speed
1. Accelerate to the desired speed.
2. Press and release
SET+. The memory
stores the vehicle speed.
3. The information display shows a green
indicator light, current gap setting and
the desired set speed.
4. Take your foot off the accelerator pedal. 5.
A lead vehicle graphic illuminates if the
system detects a vehicle in front of you.
Note: When adaptive cruise control is
active, the speedometer may vary slightly
from the set speed displayed in the
information display. Following a Vehicle WARNINGS
When following a vehicle, your
vehicle does not decelerate
automatically to a stop, nor does
your vehicle always decelerate quickly
enough to avoid a crash without driver
intervention. Always apply the brakes when
necessary. Failing to do so may result in a
crash, serious injury or death. Adaptive cruise control only warns
of vehicles detected by the radar
sensor. In some cases there may be
no warning or a delayed warning. Always
apply the brakes when necessary. Failure
to do so may result in a crash, serious injury
or death. Note:
The brakes may emit a sound when
the adaptive cruise control system is active.
When a vehicle ahead of you enters the
same lane or a slower vehicle is ahead in
the same lane, the vehicle speed adjusts
to maintain a preset gap distance. The
distance setting is adjustable.
The lead vehicle graphic illuminates.
The vehicle maintains a constant distance
from the vehicle ahead until:
• The vehicle in front of you accelerates
to a speed above the set speed.
• The vehicle in front of you moves out
of your lane or out of view.
• The vehicle speed falls below
12 mph
(20 km/h).
• You set a new gap distance.
The system applies the brakes to slow the
vehicle to maintain a safe distance from
the vehicle in front. The system applies
only limited maximum braking. Press the
brake pedal to override the system.

If the system predicts that its maximum
braking level is insufficient, an audible
warning sounds while the system
continues to brake. A red warning bar
appears on the windshield heads-up
display. Take immediate action to slow or
stop the vehicle.
The system may provide slight temporary
acceleration when you use your driver side
directional indicator while following a lead
vehicle, to aid in passing the vehicle.
Setting the Gap Distance
Note:
It is your responsibility to select a gap
appropriate to the driving conditions. Gap decrease.
A
Gap increase.
B Press the gap control to decrease or
increase the distance between your vehicle
and the vehicle in front of you. Bars in the graphic show the selected gap
distance. You can select between four gap
settings.
Note:
When you select Tow/Haul Mode,
the gap distance is increased slightly.

Due to the nature of radar technology, it is
possible to get a blockage warning and not
have a blockage. This can happen, for
example, when driving in sparse rural or
desert environments. A false blocked
condition either self clears or clears after
a key cycle.
Switching to Normal Cruise
Control
WARNING
Normal cruise control will not brake
when your vehicle is approaching
slower vehicles. Always be aware of
which mode you have selected and apply
the brakes when necessary. You can manually change from adaptive
cruise control to normal cruise control
through the information display. See
Information Messages (page 128).
The cruise control indicator light
replaces the adaptive cruise
control indicator light if you
select normal cruise control. The gap
setting does not display, the system does
not automatically respond to lead vehicles
and automatic braking remains active to
maintain set speed. The system recalls its
last setting when you start your vehicle.
