2021 FORD F-150 parking brake

Note:
During parking maneuvers, the
adaptive steering system balances the driver
workload for various steering wheel inputs
and vehicle loading conditions. Under
extreme operating conditions the system
locking device could engage. This strategy
prevents overheating and permanent
damage to the adaptive steering system.
Typical steering and driving maneuvers
allow the system to cool and return to
normal operation.
Adaptive Learning
Adaptive learning helps correct road
irregularities and improves overall handling
and steering. It communicates with the
brake system to help operate advanced
stability control and crash avoidance
systems. Additionally, whenever you
disconnect the battery or install a new
battery, you must drive your vehicle a short
distance before the system relearns the
strategy and reactivates all systems. STEERING –

PARKING AID PRECAUTIONS
WARNING: To help avoid personal
injury, always use caution when in
reverse (R) and when using the sensing
system. WARNING:
The system may not
detect objects with surfaces that absorb
reflection. Always drive with due care
and attention. Failure to take care may
result in a crash. WARNING: Traffic control systems,
fluorescent lamps, 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. WARNING:
The system may not
detect small or moving objects,
particularly those close to the ground. WARNING:
The parking aid system
can only assist you to detect objects
when your vehicle is moving at parking
speeds. To help avoid personal injury you
must take care when using the parking
aid system. WARNING:
The system may not
function if the sensor is blocked. WARNING:
In cold and severe
weather conditions the system may not
function. Rain, snow and spray can all
limit sensor performance. WARNING:
If damage occurs in the
immediate area surrounding the sensor,
have your vehicle checked as soon as
possible. Note:
If your vehicle sustains damage
leaving the sensors misaligned, this will
cause inaccurate measurements or false
alerts.
When you connect a trailer to your vehicle,
the rear parking aid detects the trailer and
provides an alert. Disable the parking aid
when you connect a trailer to prevent the
alert.
Note: Certain add-on devices installed
around the bumper or fascia may create
false alerts, for example, large trailer
hitches, bike or surfboard racks, license plate
brackets, bumper covers or any other device
that could block the normal detection zone
of the parking aid system. Aftermarket spare
tires or spare tire covers mounted to the rear
tailgate could cause false alerts from the
park aid system. Remove the add-on device
to prevent false alerts.
Note: Keep the sensors 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: When using a programmed MyKey,
you cannot switch the parking aids off. See
MyKey ™
(page 98).
REAR PARKING AID
(IF EQUIPPED)
WHAT IS THE REAR PARKING AID
Rear parking sensors detect objects behind
your vehicle when in reverse (R).
REAR PARKING AID LIMITATIONS

If your vehicle is in any forward gear, the
front parking aid provides audible warnings
and visual indication when your vehicle is
moving at a speed of 5 mph (8 km/h) or
below and the system detects an object
within the detection zone. Once your
vehicle reaches a stop, the visual indication
and audio warning stops after a few
seconds.
If your vehicle is in neutral (N), the front
and rear sensors provide visual indication
only when your vehicle is moving below a
speed of
5 mph (8 km/h) and obstacles
are detected inside the detection areas.
Once your vehicle stops, the visual
indication and audio warning stops after
a few seconds.
LOCATING THE FRONT PARKING
AID SENSORS The front parking aid sensors are in the
front bumper.
FRONT PARKING AID AUDIBLE
WARNINGS
A warning tone sounds when there is an
object within
28 in (70 cm) from the front
bumper. As your vehicle moves closer to
an object, the rate of the tone increases. The warning tone continuously sounds
when an object is 12 in (30 cm) or less from
the front bumper.
Note:
If the detected object is 12 in (30 cm)
or less from your vehicle, visual indication
remains on.
SIDE PARKING AID
(IF EQUIPPED)

When towing a trailer:
•
Obey country specific regulations for
towing a trailer.
• Do not drive faster than 70 mph
(113 km/h) during the first 500 mi
(800 km).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly
after you have traveled 50 mi (80 km).
• When stopped in congested or heavy
traffic during hot weather, place the
transmission in park (P) to aid engine
and transmission cooling and to help
A/C performance.
• Turn off the speed control with heavy
loads or in hilly terrain. The speed
control may turn off when you are
towing on long, steep slopes.
• Shift to a lower gear when driving down
a long or steep hill. Do not continuously
apply the brakes, as they may overheat
and become less effective.
• If your transmission has Grade Assist
or Tow/Haul, use this feature when
towing. This provides engine braking
and helps eliminate excessive
transmission shifting for optimum fuel
economy and transmission cooling.
• Your vehicle has AdvanceTrac with roll
stability control. When towing a trailer,
additional loads could cause the
AdvanceTrac system to engage during
cornering maneuvers. Reduce cornering
speeds to make sure that you can
maintain control of the vehicle and
