2017 FORD F150 Owners Manual

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).

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.
209
F-150 (TFC) Canada/United States of America, enUSA, First Printing Stability Control

Side-Wind Stabilization
The system applies the brakes on one side
of your vehicle to reduce the effect of a
sudden side-wind gust on your vehicle's
path. When the system turns on, the
stability and traction control light flashes,
and a message may appear in the
information display. You may notice a
slight deceleration and may still need to
make a steering correction to maintain the
intended vehicle path. The system does
not turn on for a continuous side-wind or
during turns.
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 208). Vehicle without stability control

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
indicating this feature is active. Your
vehicle maintains the speed you desire
while in this mode.
• 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
back on to use.
Refer to the Information Displays for
additional hill descent control messages.

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.
The system may not detect small or
moving objects, particularly those
close to the ground.
Traffic control systems, inclement
weather, air brakes, external motors
and fans may affect the correct
operation of the sensing system.This may
cause reduced performance or false alerts. 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 213). 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.
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 110).
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 126).
REAR PARKING AID
(If Equipped)
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
stationary or receding object farther than
12 in (30 cm)
from the corners of the
bumper, the tone sounds for only three
seconds. Once the system detects an
object approaching, the warning sounds
again.
