2021 FORD F-150 traction control

Using Trail Control
Trail Control provides you the ability to
maneuver the vehicle without using the
throttle and brake pedals.
The system controls acceleration and
braking in difficult off-road environments,
which allows you to focus on steering. See
Trail Control (page 324).
Trail Control Performance:
• Manages wheel slip to maximize
traction.
• Provides braking to maximize traction
in descents.
Using Trail One Pedal Drive
(If
Equipped)
Trail one pedal drive allows you to
accelerate and brake using only the
accelerator pedal.
Use this when driving over large obstacles,
such as rocks or logs, to help maintain a
constant vehicle speed.
In 4H, the system offers lift pedal braking
and auto hill hold functionality. See
What
Is Trail One Pedal Drive (page 325).
Note: Trail one pedal drive is only available
when the vehicle is in 4H or 4L.
AFTER DRIVING YOUR VEHICLE
OFF-ROAD - RAPTOR WARNING:
After off-road use,
before returning to the road, check the
wheels and tires for damage. Off-road
use may cause damage to your wheels
and tires that can lead to tire failure, loss
of vehicle control, serious injury or death. WARNING:
Always re-inflate tires
to recommended tire pressures before
the vehicle is operated on-road. The
recommended pressure is located on the
tire label or safety certification label,
located on the B-pillar, inside the driver's
door.
Driving off-road places more stress on your
vehicle than most on-road driving. After
driving off-road, check for damage and, if
necessary, have your vehicle repaired by
an authorized dealer.
Inspect the underbody of your vehicle by
checking tires, body structure, steering,
suspension, and exhaust system for
damage.
Check the radiator for mud and debris and
clean as needed.
Remove accumulations of plants or brush.
These things could be a fire hazard or hide
damage to the fuel lines, brake hoses, and
propeller shafts.
After operation in mud, sand, water, or
similar dirty conditions, inspect the
underbody and clean your vehicle.
AFTER DRIVING YOUR VEHICLE
OFF-ROAD WARNING:
After off-road use,
before returning to the road, check the
wheels and tires for damage. Off-road
use may cause damage to your wheels
and tires that can lead to tire failure, loss
of vehicle control, serious injury or death.

LOCATING THE TIRE LABEL
You will find a Tire Label
containing tire inflation pressure
by tire size and other important
information located on the B-Pillar
or the edge of the driver's door.
See Locating the Safety
Compliance Certification
Labels
(page 413).
DEPARTMENT OF
TRANSPORTATION UNIFORM
TIRE QUALITY GRADES Tire Quality Grades apply to new
pneumatic passenger car tires.
The Quality grades can be found
where applicable on the tire
sidewall between tread shoulder
and maximum section width. For
example:
Treadwear 200
Traction AA Temperature A.
These Tire Quality Grades are
determined by standards that the
United States Department of
Transportation has set. Tire Quality Grades apply to new
pneumatic passenger car tires.
They do not apply to deep tread,
winter-type snow tires,
space-saver or temporary use
spare tires, light truck or LT type
tires, tires with nominal rim
diameters of 10 to 12 inches or
limited production tires as defined
in Title 49 Code of Federal
Regulations Part 575.104 (c)(2).
U.S. Department of
Transportation Tire quality
grades:
The U.S. Department of
Transportation requires us to give
you the following information
about tire grades exactly as the
government has written it.
Treadwear
The treadwear grade is a
comparative rating based on the
wear rate of the tire when tested
under controlled conditions on a
specified government test course.
For example, a tire graded 150
would wear 1½ times as well on
the government course as a tire
graded 100. The relative
performance of tires depends
upon the actual conditions of their
use, however, and may depart
significantly from the norm due to
variations in driving habits, service
practices, and differences in road
characteristics and climate.

Traction AA A B C
WARNING: The traction
grade assigned to this tire is
based on straight-ahead braking
traction tests, and does not
include acceleration, cornering,
hydroplaning or peak traction
characteristics.
The traction grades, from highest
to lowest are AA, A, B, and C. The
grades represent the tire ’s ability
to stop on wet pavement as
measured under controlled
conditions on specified
government test surfaces of
asphalt and concrete. A tire
marked C may have poor traction
performance.
Temperature A B C WARNING:
The
temperature grade for this tire is
established for a tire that is
properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive
loading, either separately or in
combination, can cause heat
buildup and possible tire failure.
The temperature grades are A
(the highest), B and C,
representing the tire ’s resistance
to the generation of heat and its
ability to dissipate heat when
tested under controlled conditions
on a specified indoor laboratory test wheel. Sustained high
temperature can cause the
material of the tire to degenerate
and reduce tire life, and excessive
temperature can lead to sudden
tire failure. The grade C
corresponds to a level of
performance which all passenger
car tires must meet under the
Federal Motor Vehicle Safety
Standard No. 139. Grades B and A
represent higher levels of
performance on the laboratory
test wheel than the minimum
required by law.
INFORMATION ON THE TIRE
SIDEWALL
Both United States and Canada
Federal regulations require tire
manufacturers to place
standardized information on the
sidewall of all tires. This
information identifies and
describes the fundamental
characteristics of the tire and also
provides a U.S. DOT Tire
Identification Number for safety
standard certification and in case
of a recall.

F-150 (TFD) Canada/United States of America, enUSA, Edition date: 202104, Second-Printing Wheel and Tire Information

*Treadwear: The treadwear
grade is a comparative rating
based on the wear rate of the tire
when tested under controlled
conditions on a specified
government test course. For
example, a tire graded 150 would
wear one and one-half times as
well on the government course as
a tire graded 100.
*
Traction: The traction grades,
from highest to lowest are AA, A,
B, and C. The grades represent the
tire's ability to stop on wet
pavement as measured under
controlled conditions on specified
government test surfaces of
asphalt and concrete. A tire
marked C may have poor traction
performance.
*
Temperature: The temperature
grades are A (the highest), B and
C, representing the tire's
resistance to the generation of
heat and its ability to dissipate
heat when tested under controlled
conditions on a specified indoor
laboratory test wheel.
M. Maximum Inflation
Pressure:
Indicates the tire
manufacturers' maximum
permissible pressure or the
pressure at which the maximum
load can be carried by the tire. This
pressure is normally higher than
the vehicle manufacturer's
recommended cold inflation
pressure which can be found on
the Safety Compliance
Certification Label (affixed to
either the door hinge pillar, door-latch post, or the door edge
that meets the door-latch post,
next to the driver's seating
position), or Tire Label which is
located on the B-Pillar or the edge
of the driver
’s door. The cold
inflation pressure should never be
set lower than the recommended
pressure on the vehicle label.
The tire suppliers may have
additional markings, notes or
warnings such as standard load
or radial tubeless.

ROLLOVER WARNING
WARNING: Utility vehicles have a
significantly higher rollover rate than
other types of vehicles. WARNING:
Vehicles with a higher
center of gravity (utility and four-wheel
drive vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury
and death. WARNING:
In a rollover crash, an
unbelted person is significantly more
likely to die than a person wearing a
seatbelt. WARNING:
Do not become
overconfident in the ability of four-wheel
drive vehicles. Although a four-wheel
drive vehicle may accelerate better than
a two-wheel drive vehicle in low traction
situations, it won't stop any faster than
two-wheel drive vehicles. Always drive
at a safe speed.
Utility vehicles and trucks handle
differently than passenger cars in the
various driving conditions that are
encountered on streets, highways and
off-road. Utility vehicles and trucks are not
designed for cornering at speeds as high
as passenger cars any more than low-slung
sports cars are designed to perform
satisfactorily under off-road conditions. THE BETTER BUSINESS
