WHAT IS THE PERSONAL
SAFETY SYSTEM
An advanced safety system that protects
occupants in frontal crashes.
HOW DOES THE PERSONAL
SAFETY SYSTEM WORK
This system provides an improved level of
frontal crash protection to front seat
occupants and is designed to reduce the
risk of airbag-related injuries. The system
analyzes occupant conditions and crash
severity before activating the appropriate
safety devices. During a crash, the
restraints control module may deploy the
seatbelt pretensioners, and one or both
stages of the dual-stage airbags based on
crash severity and occupant conditions.
PERSONAL SAFETY SYSTEM
COMPONENTS
•
Driver and passenger dual-stage airbag
supplemental restraints.
• Front seat outermost seatbelts with
pretensioners, energy management
retractors and seatbelt usage sensors.
• Front passenger sensing system.
• Passenger airbag off and on indicators.
• Front crash severity sensors.
• Restraints control module with impact
and safing sensors.
• Restraint system warning light and
tone.
• The electrical wiring for the airbags,
crash sensors, seatbelt pretensioners,
front seatbelt usage sensors, front
passenger sensing system and
indicator lights.

F-150 (TFD) Canada/United States of America, enUSA, Edition date: 202104, Second-Printing Personal Safety System
™

The system does not function if:
•
The passive key frequencies are
jammed.
• The key battery has no charge.
RESTARTING THE ENGINE AFTER
STOPPING IT - VEHICLES WITH:
PUSH BUTTON START
The system allows you to start the engine
within 10 seconds of switching it off, even
if it does not detect a valid passive key.
Within 10 seconds of switching the engine
off, fully press the brake pedal and press
the push button ignition switch. After 10
seconds, you can no longer start the engine
if the system does not detect a valid
passive key.
When you start the engine, it remains
running until you press the push button
ignition switch, even if your vehicle does
not detect a valid passive key. If you open
and close a door when the engine is
running, the system searches for a valid
passive key.
ENGINE BLOCK HEATER (IF
EQUIPPED)
ENGINE BLOCK HEATER
PRECAUTIONS WARNING:
Failure to follow engine
block heater instructions could result in
property damage or serious personal
injury. WARNING: Do not use your heater
with ungrounded electrical systems or
two-pronged adapters. There is a risk of
electrical shock. WARNING:
Do not fully close the
hood, or allow it to drop under its own
weight when using the engine block
heater. This could damage the power
cable and may cause an electrical short
resulting in fire, injury and property
damage.
We recommend that you do the following
for a safe and correct operation:
• Use a 16-gauge outdoor extension cord
that is product certified by
Underwriter ’s Laboratory (UL) or
Canadian Standards Association
(CSA). This extension cord must be
suitable for use outdoors, in cold
temperatures, and be clearly marked
Suitable for Use with Outdoor
Appliances. Do not use an indoor
extension cord outdoors. This could
result in an electric shock or become a
fire hazard.
• Use as short an extension cord as
possible.
• Do not use multiple extension cords.
• Make sure that when in operation, the
extension cord plug and engine block
heater cord plug connections are free
and clear of water. This could cause an
electric shock or fire.
• If the engine block heater cord is under
the hood, do not remove the wiring
from its original location. Do not close
the hood on the extension wiring.
• Park your vehicle in a clean area, clear
of combustible materials.
• Firmly connect the engine block heater
cord and the extension cord.
• Check the extension cord for heat
anywhere when the system has been
operating for approximately 30
minutes.

CONNECTING A TRAILER
PRECAUTIONS
Do not tow a trailer until you drive your
vehicle at least 1,000 mi (1,600 km).
Consult your local motor vehicle laws for
towing a trailer.
See the instructions included with towing
accessories for the proper installation and
adjustment specifications.
Service your vehicle more frequently if you
tow a trailer. See
Normal Scheduled
Maintenance (page 667).
If you use a rental trailer, follow the
instructions the rental agency gives you.
When attaching the trailer wiring connector
to your vehicle, only use a proper fitting
connector that works with the vehicle and
trailer functions.
Account for the trailer coupler weight as
part of your vehicle load when calculating
the total vehicle weight.
Do not exceed the load limits. See
Calculating the Load Limit
(page 415).
HITCHES
HOOKING UP A TRAILER USING A
WEIGHT-DISTRIBUTING HITCH WARNING: Do not adjust the spring
bars so that your vehicle's rear bumper
is higher than before attaching the trailer.
Doing so will defeat the function of the
weight-distributing hitch, which may
cause unpredictable handling, and could
result in serious personal injury.
A weight-distributing hitch helps distribute
tongue load to all towing vehicle and trailer
wheels. For more information, visit the links
in the following table. Website

F-150 (TFD) Canada/United States of America, enUSA, Edition date: 202104, Second-Printing Connecting a Trailer

When attaching the trailer wiring connector
to your vehicle, only use a proper fitting
connector that works with the vehicle and
trailer functions.
Safety Chains
Install trailer safety chains to the trailer
hitch as recommended by the
manufacturer. Cross the chains under the
trailer coupler and allow enough slack for
turning tight corners. Do not allow the
chains to drag on the ground.
Note:
Do not attach safety chains to the
bumper. Always connect the safety chains
to the frame or hook retainers of your trailer
hitch. If the trailer safety chain hook has a latch,
fully close the latch.

F-150 (TFD) Canada/United States of America, enUSA, Edition date: 202104, Second-Printing Connecting a Trailer

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
trailer if the AdvanceTrac system
engages. •
Allow more distance for stopping with
a trailer attached. Anticipate stops and
gradually brake.
• Avoid parking on a slope. However, if
you must park on a slope, turn the
steering wheel to point your vehicle
tires away from traffic flow, set the
parking brake, place the transmission
in park (P) and place wheel chocks in
front and back of the trailer wheels.
Note: Chocks are not included with your
vehicle.
LAUNCHING OR RETRIEVING
A BOAT OR PERSONAL
WATERCRAFT
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
6 in (15 cm) could allow water
to enter vehicle components, causing
internal damage to the components and
affecting driveability, emissions and
reliability.
Note: Replace the rear axle lubricant
anytime the rear axle has been submerged
in water.
Note: Disconnect the trailer wiring
connector before backing the trailer into the
water.
Note: Reconnect the trailer wiring
connector after removing the trailer from
the water.
