steering FORD F-150 2020 Repair Manual

Before Towing a Trailer
Practice turning, stopping and backing up
to get the feel of your vehicle-trailer
combination before starting on a trip.
When turning, make wider turns so the
trailer wheels clear curbs and other
obstacles.
When 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 automatically
when you are towing on long, steep
grades.
• Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective.
• If your transmission is equipped with a
Grade Assist or Tow/Haul feature, use
this feature when towing. This provides
engine braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and
transmission cooling.
• If your vehicle is equipped with
AdvanceTrac with RSC, this system
may turn on during typical cornering
maneuvers with a heavily loaded trailer.
This is normal. Turning the corner at a
slower speed while towing may reduce
this tendency. •
If you are towing a trailer frequently in
hot weather, hilly conditions, at the
gross combined weight rating (or any
combination of these factors), consider
refilling your rear axle with synthetic
gear lubricant (if the axle is not already
filled with it). See
Capacities and
Specifications (page 424).
• Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a grade. However, if
you must park on a grade:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the automatic transmission in park (P).
4. Place wheel chocks in front and back of the trailer wheels. Chocks are not
included with your vehicle.
Your vehicle may be equipped with a
temporary or conventional spare tire. A
temporary spare tire is different in diameter
or width, tread-type, or is from a different
manufacturer than the road tires on your
vehicle. Consult information on the tire
label or Safety Compliance label for
limitations when using.
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer
before
backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after
removing the trailer from the water.
320
F-150 (TFC) Canada/United States of America, enUSA, Edition date: 201907, Third-Printing- Towing

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 these limits may allow water to
enter vehicle components:
• Causing internal damage to the
components.
• Affecting driveability, emissions, and
reliability.
Replace the rear axle lubricant anytime
the rear axle has been submerged in water.
Water may have contaminated the rear
axle lubricant, which is not normally
checked or changed unless a leak is
suspected or other axle repair is required.
TOWING THE VEHICLE ON
FOUR WHEELS WARNING:
If your vehicle has a
steering wheel lock make sure the
ignition is in the accessory or on position
when being towed. Emergency Towing
If your vehicle becomes inoperable
(without access to wheel dollies,
car-hauling trailer, or flatbed transport
vehicle), it can be flat-towed (all wheels
on the ground, regardless of the powertrain
and transmission configuration) under the
following conditions:
•
Your vehicle is facing forward for
towing in a forward direction.
• Place the transmission in neutral (N).
If you cannot move the transmission
into neutral (N), you may need to
override it. See
Transmission (page
217).
• Maximum speed is 35 mph (56 km/h).
• Maximum distance is
50 mi (80 km).
Recreational Towing
Note: Put your climate control system in
recirculated air mode to prevent exhaust
fumes from entering your vehicle. See
Climate Control
(page 151).
Follow these guidelines if you have a need
for recreational towing, such as towing
your vehicle behind a motorhome. These
guidelines are designed to prevent damage
to your transmission.
Two-wheel Drive Vehicles
You cannot tow a two-wheel drive vehicle
with any wheels on the ground as vehicle
or transmission damage may occur. You
must tow your vehicle with all four wheels
off the ground, such as when using a
car-hauling trailer.
321
F-150 (TFC) Canada/United States of America, enUSA, Edition date: 201907, Third-Printing- Towing

forest trail or the open desert. Before going
off-roading, consult with your local
governmental agencies to determine
designated off-road trails and recreation
areas. Also, be sure to understand any
off-road vehicle registration requirements
for the area in which you plan on driving.
Tread Lightly is an educational program
designed to increase public awareness of
land-use regulations and responsibilities
in our nation
’s wilderness areas. Ford joins
the U.S. Forest Service and Bureau of Land
Management in encouraging you to help
preserve our national forest and other
public and private lands by treading lightly.
Before taking your vehicle off-roading, a
basic vehicle inspection should be done to
make sure that the vehicle is in top working
condition.
It is always recommended that at least
two vehicles are used while off-roading.
The buddy system helps make sure that
help is close at hand should a vehicle
become stuck or damaged. It is also wise
to take supplies such as a first aid kit,
supply of water, tow strap, cell or satellite
phone with you any time an off-road
excursion is planned.
Basic Off-road Driving Techniques
• Grip the steering wheel with thumbs
on the outside of the rim. This will
reduce the risk of injury due to abrupt
steering wheel motions that occur
when negotiating rough terrain. Do not
grip the steering wheel with thumbs
inside the rim.
• Throttle, brake and steering inputs
should be made in a smooth and
controlled manner. Sudden inputs to
the controls can cause loss of traction
or upset the vehicle, especially while
on sloped terrain or while crossing
obstacles such as rocks or logs. •
Look ahead on your route noting
upcoming obstacles, surface texture
or color changes or any other factors
which may indicate a change in
available traction, and adjust the
vehicle speed and route accordingly.
During pre-run, mark obstacles with
GPS markers to make sure appropriate
speeds are used to avoid potential
vehicle damage.
• When driving off-road, if the front or
rear suspension is bottoming out
and/or excessive contact with the
skid-plates is encountered, reduce
vehicle speed to avoid potential
damage to the vehicle.
• When running with other vehicles, it is
recommended that communication is
used, and the lead vehicle notify other
vehicles of obstacles that could cause
potential vehicle damage.
• Always keep available ground
clearance in mind and pick a route that
minimizes the risk of catching the
underside of the vehicle on an obstacle.
• When negotiating low speed obstacles,
applying light brake pressure in
conjunction with the throttle will help
prevent the vehicle from jerking and
will allow you to negotiate the obstacle
in a more controlled manner. Using 4L
will also help with this.
• Use and equip supplemental safety
equipment as discussed later in this
chapter.
• Please consult your local off-road
group for other helpful tips.
• Off-roading requires a high degree of
concentration. Even if your local law
does not prohibit alcohol use while
driving off-road, Ford strongly
recommends against drinking if you
plan to off-road.

Crossing Obstacles
•
Review the path ahead before
attempting to cross any obstacle. It is
best if the obstacle is reviewed from
outside the vehicle so that there is a
good understanding of terrain condition
both in front of and behind the
obstacle.
• Approach obstacles slowly and slowly
inch the vehicle over.
• If a large obstacle such as a rock
cannot be avoided, choose a path that
places the rock directly under the tire
rather than the undercarriage of the
vehicle. This will help prevent damage
to the vehicle.
• Ditches and washouts should be
crossed at a 45 degree angle, allowing
each wheel to independently cross the
obstacle.
Hill Climbing WARNING: Extreme care should
be used when steering the vehicle in
reverse down a slope so as not to cause
the vehicle to swerve out of control.
• Always attempt to climb a steep hill
along the fall line of the slope and not
diagonally.
• If the vehicle is unable to make it up
the hill, DO NOT attempt to turn back
down the slope. Place the vehicle in
low range and slowly back down in
reverse.
• When descending a steep slope, select
low gear and engage hill descent
control. Use the throttle and brake
pedals to control your descent speed
as described earlier in this section using
hill descent control. Note that hill
descent control is functional in reverse
and should be used in this situation. BREAKING-IN
You need to break in new tires for
approximately
300 mi (480 km). During
this time, your vehicle may exhibit some
unusual driving characteristics.
Avoid driving too fast during the first
1,000 mi (1,600 km)
. Vary your speed
frequently and change up through the
gears early. Do not labor the engine.
Do not tow during the first
1,000 mi
(1,600 km).
DRIVING THROUGH WATER WARNING:
Do not drive through
flowing or deep water as you may lose
control of your vehicle.
Note: Driving through standing water can
cause vehicle damage.
Note: Engine damage can occur if water
enters the air filter.
Before driving through standing water,
check the depth. Never drive through water
that is higher than the bottom of the wheel
hubs. 326
F-150 (TFC) Canada/United States of America, enUSA, Edition date: 201907, Third-Printing- Driving HintsE176913

When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction may
be limited. After driving through water and
as soon as it is safe to do so:
•
Lightly press the brake pedal to dry the
brakes and to check that they work.
• Check that the horn works.
• Check that the exterior lights work.
• Turn the steering wheel to check that
the steering power assist works.
SNOW PLOWING
We recommend the four-wheel drive F-150
in XL, XLT or Lariat trim levels with the 5.0L
engine and snowplow option for residential
snowplowing only. We do not recommend
the F-150 with the automatic four-wheel
drive system for snowplowing.
Do not use F-150 vehicles equipped with
the 2.7L, 3.0L, 3.3L or 3.5L engines for
snowplowing.
Installing the Snowplow
Weight limits and guidelines for selecting
and installing the snowplow are in the Ford
Truck Body Builders Layout Book,
snowplow section, found at
www.fleet.ford.com/truckbbas. A typical installation affects the following:
•
Certification to government safety laws
such as occupant protection and airbag
deployment, braking, and lighting. Look
for an Alterer ’s Label on your vehicle
from the snowplow installer certifying
that the installation meets all
applicable Federal Motor Vehicle
Safety Standards (FMVSS).
• The Front Gross Axle Weight Rating
(GAWR) is on the upper left side of the
vehicle ’s Safety Compliance
Certification Label. This is the total
weight that front axle supports, which
includes the vehicle weight plus any
auxiliary equipment such as snowplow
frame-mounted hardware that can be
added to the vehicle and satisfy Ford
compliance certification to FMVSS. Do
not exceed FGAWR or Gross Vehicle
Weight Rating (GVWR).
• Rear ballast weight behind the rear
axle may be required to prevent
exceeding the FGAWR, and provide
front-to-rear weight balance for proper
braking and steering.
• Front wheel toe may require
re-adjustment to prevent premature
uneven tire wear. Specifications are in
the Ford Workshop Manual.
• Headlight aim may require adjustment.
• The tire air pressures recommended
for general driving are on the vehicle ’s
Safety Certification Label. The
maximum cold inflation pressure for
the tire and associated load rating are
on the tire sidewall. Tire air pressure
may require re-adjustment within these
pressure limits to accommodate the
additional weight of the snowplow
installation.
• Federal and some local regulations
require additional exterior lamps for
snowplow-equipped vehicles. Contact
an authorized dealer for additional
information.

F-150 (TFC) Canada/United States of America, enUSA, Edition date: 201907, Third-Printing- Driving Hints

Snowplow Mode (If Equipped)
Press the snowplow button on the
instrument panel to switch on snowplow
mode. The button illuminates when in
snowplow mode. A message appears in
the information display indicating that
features are turned off when in snowplow
mode.
The following features are disabled when
in snowplow mode:
• 110V inverter.
• Fog lamps.
• Heated steering wheel.
• Heated front and rear seats.
• Massaging seats.
The body module also activates the
snowplow relay that provides power to
aftermarket snowplow controls.
Switch off snowplow mode by pressing
the snowplow button or switching off the
ignition. The snowplow button is no longer
illuminated and features are turned on.
Note: The electrical system is designed to
support the addition of a residential
snowplow (up to 60 Amps continuous) and
snowplow lights (up to 20 Amps
continuous) using snowplow mode. The
system is not designed to support snowplow
usage with additional electrical aftermarket
accessories.
Operating the Vehicle with the
Snowplow Attached
Note: Drive the vehicle at least
500 mi
(800 km) before using your vehicle for snow
removal.
We recommend vehicle speed does not
exceed
45 mph (72 km/h) when
snowplowing. The attached snowplow blade restricts
airflow to the radiator, and may cause the
engine to run at a higher temperature.
Attention to engine temperature is
especially important when outside
temperatures are above freezing. Angle
the blade to maximize airflow to the
radiator and monitor engine temperature
to determine whether a left or right angle
provides the best performance.
Follow the severe duty schedule in your
Scheduled Maintenance information for
engine oil and transmission fluid change
intervals.
Snowplowing with your Airbag
Equipped Vehicle
WARNING:
Do not attempt to
service, repair, or modify the airbag
supplemental restraint systems or its
fuses on a vehicle containing air bags as
you could be seriously injured or killed.
Contact your authorized dealer as soon
as possible. WARNING:
All occupants of your
vehicle, including the driver, should
always properly wear their seatbelts,
even when an airbag supplemental
restraint system is provided. Failure to
properly wear your seatbelt could
seriously increase the risk of injury or
death. WARNING:
Modifying or adding
equipment to the front end of your
vehicle (including hood, bumper system,
frame, front end body structure, tow
hooks and hood pins) may affect the
performance of the airbag system,
increasing the risk of injury. Do not
modify or add equipment to the front
end of your vehicle.
