warning light FORD F150 2017 13.G Service Manual

GENERAL INFORMATION
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out. Have the
system checked by an authorized dealer. If
your vehicle has continuous vibration or
shudder in the steering wheel while braking,
have it checked by an authorized dealer.
Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See Cleaning the Wheels
(page 346). See
Warning Lamps and
Indicators (page 105).
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedal
becomes stuck or entrapped, apply steady
and firm pressure to the brake pedal to
slow the vehicle and reduce engine power.
If you experience this condition, apply the
brakes and bring your vehicle to a safe
stop. Move the transmission to park (P),
switch the engine off and apply the parking
brake. Inspect the accelerator pedal for
any interference. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.
Brake Assist
Brake assist detects when you brake
rapidly by measuring the rate at which you
press the brake pedal. It provides
maximum braking efficiency as long as you
press the pedal, and can reduce stopping
distances in critical situations. Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking. This lamp momentarily
illuminates when you turn the
ignition on. If the light does not
illuminate during start up, remains on or
flashes, the system may be disabled. Have
the system checked by an authorized
dealer. If the anti-lock brake system is
disabled, normal braking is still effective. If the brake warning lamp
remains illuminated after you
release the parking brake, have
the system checked by an authorized
dealer.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
Note: When the system is operating, the
brake pedal may pulse and may travel
further. Maintain pressure on the brake
pedal. You may also hear a noise from the
system. This is normal.
The anti-lock braking system will not
eliminate the risks when:
• You drive too closely to the vehicle in
front of you.
• Your vehicle is hydroplaning.
• You take corners too fast.
• The road surface is poor.
203
F-150 (TFC) Canada/United States of America, enUSA, First Printing BrakesE144522 E144522

The brake system warning lamp will flash
for approximately two seconds and then
illuminate to confirm that the electric
parking brake has been applied. See
Information Displays (page 110).
Note: The brake system warning lamp will
remain illuminated for about ten seconds if
you switch the ignition off with the parking
brake applied, or apply the parking brake
while the ignition is off.
Note: The electric parking brake will not
automatically apply. You must apply the
electric parking brake using the electric
parking brake switch.
Applying the Electric Parking
Brake When the Vehicle is Moving WARNINGS
Applying the electric parking brake
while moving will result in use of the
anti-lock braking system. Do not use
the electric parking brake system when the
vehicle is moving unless the normal brake
system is unable to stop the vehicle. With the exception of emergency
conditions (for example, the brake
pedal does not work or is blocked),
do not apply the electric parking brake
while the vehicle is moving. On bends, or
poor road surfaces or weather conditions,
emergency braking can cause the vehicle
to skid out of control or off the road. If you apply the electric parking brake when
your vehicle is moving, the brake system
warning lamp will illuminate and a warning
tone will sound. See
Information
Displays (page 110).
If your vehicle speed is above
4 mph
(6 km/h), the braking force is applied as
long as the switch is pulled. Release or
press the switch or press the accelerator
pedal to stop the braking force. Releasing the Electric Parking
Brake
You can release the electric parking brake
either manually by pressing the switch or
automatically.
Manual Release
WARNING
If the brake system warning light
remains illuminated or flashes after
you have released the parking brake,
there could be a problem with your braking
system. Have the system checked by an
authorized dealer as soon as possible. You can manually release the electric
parking brake by:
•
Switching the ignition on.
• Pressing the brake pedal.
• Pressing the electric parking brake
switch.
When the electric parking brake is released,
the brake system warning lamp will turn
off.
Driving With a Trailer
Depending on the grade and the weight of
the trailer, your vehicle and trailer may roll
backwards slightly when you start on a
slope.
205
F-150 (TFC) Canada/United States of America, enUSA, First Printing BrakesE169086

To prevent this from happening, do the
following:
1. Pull the switch up and hold it in this
position.
2. Drive your vehicle, then release the switch when you notice that the engine
has developed sufficient driving force.
Automatic Release - Drive Away
Release
Your vehicle will automatically release the
parking brake if:
• The driver door is closed.
• The transmission is in a forward or
reverse gear.
• The vehicle is accelerated.
• There are no faults detected in the
parking brake system.
The brake system warning lamp will go off
to confirm that you have released the
electric parking brake.
Note: If the electric parking brake warning
lamp stays illuminated, the electric parking
brake will not automatically release. You
must release the electric parking brake using
the electric parking brake switch.
Note: The electric parking brake drive away
release makes starting on a hill easier. This
feature will release the parking brake
automatically when the vehicle has
sufficient drive force to move up the hill.
Battery With No Charge WARNING
You will not be able to apply or
release the electric parking brake if
the battery is low or has no charge.
If the battery is low or has no charge, use
jumper cables and a booster battery. HILL START ASSIST WARNINGS
The system does not replace the
parking brake. When you leave your
vehicle, always apply the parking
brake. Failure to leave your vehicle securely
parked may lead to a crash or injury. See
Parking Brake (page 204). 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 system will turn off if a
malfunction is apparent or if you rev
the engine excessively. Failure to
take care may result in the loss of control
of your vehicle, serious personal injury or
death. The system makes it easier to pull away
when your vehicle is on a slope without the
need to use the parking brake.
When the system is active, your vehicle
remains stationary on the slope for two to
three seconds after you release the brake
pedal. This allows time to move your foot
from the brake to the accelerator pedal.
The system releases the brakes
automatically once the engine has
developed sufficient torque to prevent your
vehicle from rolling down the slope. This
is an advantage when pulling away on a
slope, for example from a car park ramp,
traffic lights or when reversing uphill into
a parking space.
Note:
The system only functions when you
bring your vehicle to a complete standstill
in an uphill gear (for example, drive (D)
when facing uphill or reverse (R) when
facing downhill).
206
F-150 (TFC) Canada/United States of America, enUSA, First Printing Brakes

Note:
There is no warning light to indicate
the system is either on or off.
Using Hill Start Assist
1. Press the brake pedal to bring your vehicle to a complete standstill. Keep
the brake pedal pressed.
2. If the sensors detect that your vehicle is on a slope, the system activates
automatically.
3. When you remove your foot from the brake pedal, your vehicle remains on
the slope without rolling away for
about two to three seconds. This hold
time automatically extends if you are
in the process of driving off.
4. Drive off in the normal manner. The system releases the brakes
automatically.
Note: When you remove your foot from the
brake pedal and press the pedal again when
the system is active, you will experience
significantly reduced brake pedal travel. This
is normal.
Switching the System On and Off
Vehicles with Manual Transmission
You can switch this feature on or off in the
information display. The system
remembers the last setting when you start
your vehicle.
Vehicles with Automatic Transmission
You cannot turn the system on or off.
When you switch the ignition on, the
system automatically turns on.

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 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
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. Switching the System Off The switch for the stability and traction
control system is on the instrument panel.
When you switch the system off, a
message and an illuminated icon appear
on the instrument cluster.
Use the switch again to return the traction
control system to normal operation.
Your vehicle may have MyKey restrictions
regarding this feature. See Principle of
Operation (page 59).
System Indicator Lights and
Messages The stability and traction control
light temporarily illuminates on
engine start-up and flashes:
• When a driving condition activates
either of the systems.
• 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.
• When you select an alternative stability
control mode.

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 the stability control or traction control
system detects a fault, the following may
occur:
•
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 the stability control or traction control
system activates, the following may occur:
• 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 pedal, the
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 the brakes to one or more of the
wheels individually and, if necessary,
reducing engine power.
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.

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,
you must apply the parking brake or place
the vehicle in P (Park), or it may roll away. Hill descent control allows you 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 you cannot use the system to
set or maintain the descent speed.
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 provides a
warning in the message center and a tone
sounds 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 on the
instrument panel. A light in the
cluster illuminates and a tone sounds
when you switch this on. To increase descent speed, press the
accelerator pedal until you reach the speed
you desire. To decrease descent speed,
press the brake pedal until you reach the
speed you desire.
When accelerating or decelerating, once
you reach the descent speed you desire,
remove your feet from the pedals and the
hill descent control maintains the vehicle
speed you chose.
Note:
You may observe a noise from the
ABS pump motor during hill descent control
operation. This is a normal characteristic of
the ABS and is no reason for concern.
Hill descent modes
• At speeds between
2 mph (3 km/h)
and 20 mph (32 km/h): When you
press this button, the light flashes

• At speeds between
20 mph (32 km/h)
and 40 mph (64 km/h): When you
press this button, the light is solid and
a message appears in the information
display indicating this feature is active.
Your vehicle does not maintain the
speed you desire and you cannot set
your descent speed.
• At speeds above
40 mph (64 km/h):
When you press this button, the system
turns this feature off and no light or
message appears in the information
display. You need to switch this feature

your vehicle as they move from the green
zone to the yellow or red zones. Use the
side view mirrors and rear view mirror to
get better coverage on both sides and rear
of your vehicle.
Obstacle Distance Indicator (If
Equipped) The system will provide an image of your
vehicle and the sensor zones. The zones
will highlight green, yellow and red when
the parking aid sensors detect an object in
the coverage area.
Manual Zoom
WARNING
When manual zoom is on, the full
area behind your vehicle may not
show. Be aware of your surroundings
when using the manual zoom feature. Note:
Manual zoom is only available when
the transmission is in reverse (R).
Note: Only the centerline shows when you
enable manual zoom.
Selectable settings for this feature are
Zoom in (+) and Zoom out (-). Press the

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
