2018 FORD F-150 power steering

GENERAL INFORMATION
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out and an
authorized dealer should check them. If the
vehicle has continuous vibration or shudder
in the steering wheel while braking, an
authorized dealer should check your vehicle.
Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See Cleaning the Wheels
(page 379). See
Warning Lamps and
Indicators (page 108).
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedal
becomes stuck or entrapped, apply steady
and firm pressure to the brake pedal to
slow the vehicle and reduce engine power.
If you experience this condition, apply the
brakes and bring your vehicle to a safe
stop. Switch the engine off, move the
transmission to park (P) and apply the
parking brake. Inspect the accelerator
pedal and the area around it for any items
or debris that may be obstructing its
movement.If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer. Emergency Brake Assist
Emergency brake assist detects when you
brake heavily by measuring the rate at
which you press the brake pedal. It
provides maximum braking efficiency as
long as you press the pedal. Emergency
brake assist can reduce stopping distances
in critical situations.
Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking.
This lamp momentarily
illuminates when you switch the
ignition on. If the light does not
illuminate during start up, remains on or
flashes, the anti-lock braking system may
be disabled. Have the system checked by
an authorized dealer. If the anti-lock brake
system is disabled, normal braking is still
effective. If the brake warning lamp
illuminates with the parking
brake released, have your brake
system serviced immediately.
It also illuminates momentarily when you
switch the ignition on to confirm the lamp
is functional. If it does not illuminate when
you switch the ignition on, or begins to
flash at any time, have the system checked
by an authorized dealer.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
The anti-lock braking system does not
eliminate the risks when:
• You drive too closely to the vehicle in
front of you.
• Your vehicle is hydroplaning.

PRINCIPLE OF OPERATION
WARNING: 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. WARNING:
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 helps to prevent your vehicle
skidding or laterally sliding by individually
applying the brakes to one or more wheels
and, if necessary, reducing engine power.
Roll Stability Control
The system helps to prevent rollovers by
detecting your vehicle's roll motion, and
individually applying the brakes to one or
more wheels.

Note:
The system may not correctly operate
when towing a trailer. For vehicles with an
approved trailer tow module and tow bar,
the system turns off when you attach a
trailer. For vehicles with an aftermarket
trailer tow module or tow bar, we
recommend that you switch the system off
when you attach a trailer.
To permanently switch the system off,
contact an authorized dealer.
STEERING
Electric Power Steering WARNING: The electric power
steering system has diagnostic checks
that continuously monitor the system. If
a fault is detected, a message displays
in the information display. Stop your
vehicle as soon as it is safe to do so.
Switch the ignition off. After at least 10
seconds, switch the ignition on and
watch the information display for a
steering system warning message. If a
steering system warning message
returns, have the system checked by an
authorized dealer. WARNING:
If the system detects
an error, you may not feel a difference in
the steering, however a serious condition
may exist. Obtain immediate service
from an authorized dealer, failure to do
so may result in loss of steering control.
Your vehicle has an electric power steering
system. There is no fluid reservoir. No
maintenance is required.
If your vehicle loses electrical power while
you are driving, electric power steering
assistance is lost. The steering system still
operates and you can steer your vehicle
manually. Manually steering your vehicle
requires more effort. Extreme continuous steering may increase
the effort required for you to steer your
vehicle. This increased effort prevents
overheating and permanent damage to
the steering system. You do not lose the
ability to steer your vehicle manually.
Typical steering and driving maneuvers
allow the system to cool and return to
normal operation.
Steering Tips
If the steering wanders or pulls, check for:
•
Correct tire pressures.
• Uneven tire wear.
• Loose or worn suspension
components.
• Loose or worn steering components.
• Improper vehicle alignment.
Note: A high crown in the road or high
crosswinds may also make the steering
seem to wander or pull.
Adaptive Learning
The electronic power steering system
adaptive learning helps correct road
irregularities and improves overall handling
and steering feel. It communicates with
the brake system to help operate
advanced stability control and accident
avoidance systems. Additionally, whenever
the battery is disconnected or a new
battery installed, you must drive your
vehicle a short distance before the system
relearns the strategy and reactivates all
systems.

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
207).
• Maximum speed is 35 mph (56 km/h).
• Maximum distance is
50 mi (80 km).
Recreational Towing

SNOWPLOWING
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.
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.
