2020 FORD F450 SUPER DUTY power steering

Study your owner's manual and any
supplements for specific information about
equipment features, instructions for safe
driving and additional precautions to
reduce the risk of an accident or serious
injury.
Four-wheel drive system (If Equipped)
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.
A vehicle equipped with four-wheel drive,
when selected, has the ability to use all
four wheels to power itself. This increases
traction which may enable you to safely
drive over terrain and road conditions that
a conventional two-wheel drive vehicle
cannot.
Power is supplied to all four wheels
through a transfer case or power transfer
unit. Four-wheel drive vehicles allow you
to select different modes as necessary. For
information on transfer case operation and
shifting procedures, See
Four-Wheel
Drive (page 212). For information on
transfer case maintenance, See
Maintenance (page 342). You should
become thoroughly familiar with this
information before you operate your
vehicle.
On some four-wheel drive vehicles, the
initial shift from two-wheel to four-wheel
drive when the vehicle is moving can cause
a momentary clunk and ratcheting sound.
These sounds are normal and are not
cause for concern. In four-wheel drive vehicles, the size of the
spare tire relative to the remaining tires can
have an effect on the 4x4 system. If there
is a significant difference between the size
of a spare and the remaining tires,
four-wheel drive functionality may be
limited.
See Using Four-Wheel Drive
(page 212).
How your vehicle differs from
other vehicles
Sport utility vehicles and trucks can differ
from some other vehicles in a few
noticeable ways. Your vehicle may be:
• Higher - to allow higher load carrying
capacity and to allow it to travel over
rough terrain without getting hung up
or damaging underbody components.
• Shorter - to give it the capability to
approach inclines and drive over the
crest of a hill without getting hung up
or damaging underbody components.
All other things held equal, a shorter
wheelbase may make your vehicle
quicker to respond to steering inputs
than a vehicle with a longer wheelbase.
• Narrower - to provide greater
maneuverability in tight spaces,
particularly in off-road use.
As a result of the above dimensional
differences, Sport utility vehicles and
trucks often have a higher center of gravity
and a greater difference in center of gravity
between the loaded and unloaded
condition. These differences that make
your vehicle so versatile also make it
handle differently than an ordinary
passenger car.

non-recommended tires and wheels can
cause steering, suspension, axle, transfer
case or power transfer unit failure.
Follow the Ford recommended tire
inflation pressure found on the Safety
Compliance Certification Label (on the
door hinge pillar, door latch post or the
door edge that meets the door latch
post, next to the driver seat), or Tire
Label on the B-Pillar or the edge of the
driver door. Failure to follow the tire
pressure recommendations can cause
uneven treadwear patterns and
adversely affect the way your vehicle
handles.
WARNING: Do not use snow chains
on snow-free roads.
Note: Do not use snow chains on vehicles
with LT275/65R20 or LT 285/75R18 sized
tires.
The tires on your vehicle have all-weather
treads to provide traction in rain and snow.
However, in some climates, you may need
to use snow tires and cables. If you need
to use cables, we recommend that you use
steel wheels of the same size and
specification, as cables may chip
aluminum wheels.
Note: The suspension insulation and
bumpers will help prevent vehicle damage.
Do not remove these components from your
vehicle when using snow tires and chains.
Follow these guidelines when using snow
tires and chains:
• If possible, avoid fully loading your
vehicle.
• Use only SAE Class S chains.
• Install chains securely, verifying that
the chains do not touch any wiring,
brake lines or fuel lines.
• Only install snow chains on the rear
axle. •
For Dual Rear Wheel (DRW) vehicles,
only install snow chains on the outer
wheel of each pair.
• Drive cautiously. If you hear the chains
rub or bang against your vehicle, stop
and retighten the chains. If this does
not work, remove the chains to prevent
damage to your vehicle.
• Remove the tire chains when you no
longer need them. Do not use tire
chains on dry roads.
If you have any questions regarding snow
chains or cables, please contact your
authorized dealer.
TIRE PRESSURE MONITORING
SYSTEM
Vehicle Tire Pressure Monitoring
System WARNING:
The tire pressure
monitoring system is not a substitute for
manually checking tire pressures. You
should periodically check tire pressures
using a pressure gauge. Failure to
correctly maintain tire pressures could
increase the risk of tire failure, loss of
control, vehicle rollover and personal
injury. Check each tire, including the
spare, if provided, monthly when
cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard or tire
inflation pressure label. If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or tire
inflation pressure label, you should
determine the proper tire inflation pressure
for those tires.

If a crash deploys an airbag (excluding
knee airbags and rear inflatable safety
belts [if equipped]) or activates the fuel
pump shut-off, your SYNC-equipped
vehicle may be able to contact emergency
services by dialing 911 through a paired and
connected Bluetooth-enabled phone.
See Supplementary Restraints System
(page 45). Important information about
airbag deployment is in this chapter.
See Roadside Emergencies (page 320).
Important information about the fuel pump
shut-off is in this chapter.
Setting 911 Assist On or Off
Press the Settings button then select: Action and Description
Menu
Item
Select the desired option, on
or off.
911 Assist
To make sure that 911 Assist works
properly:
• SYNC must be powered and working
properly at the time of the incident and
throughout feature activation and use.
• The 911 Assist feature must be set on
before the incident.
• You must pair and connect a Bluetooth
enabled and compatible cell phone to
SYNC.
• A connected Bluetooth enabled phone
must have the ability to make and
maintain an outgoing call at the time
of the incident.
• A connected Bluetooth enabled phone
must have adequate network coverage,
battery power and signal strength.
• The vehicle must have battery power
and be located in the U.S., Canada or
in a territory in which 911 is the
emergency number. In the Event of a Crash
Not all crashes deploy an airbag or activate
the fuel pump shut-off (the triggers for 911
Assist). If a connected cell phone sustains
damage or loses its connection to SYNC
during a crash, SYNC searches for and tries
to connect to a previously paired cell
phone; SYNC then attempts to call the
emergency services.
Before making the call:
•
SYNC provides a short window of time
(about 10 seconds) to cancel the call.
If you fail to cancel the call, SYNC
attempts to dial 911.
• SYNC says the following, or a similar
message: "SYNC will attempt to call
911, to cancel the call, press Cancel on
your screen or press and hold the
phone button on your steering wheel".
If you do not cancel the call, and SYNC
makes a successful call, a pre-recorded
message plays for the 911 operator, and
then the occupant(s) in your vehicle are
able to talk with the operator. Be prepared
to provide your name, phone number and
location immediately, because not all 911
systems are capable of receiving this
information electronically.
911 Assist May Not Work If
• Your cellular phone or 911 Assist
hardware sustains damage in a crash.
• The vehicle's battery or the SYNC
system has no power.
• The phone(s) thrown from your vehicle
are the ones paired and connected to
the system.
