2021 FORD F-450 brake

For Vehicles with Tremor Off-Road
Package
Your vehicle equipped with Tremor
Off-Road package is capable of traveling
through water at a maximum depth of
33 in (837 mm). When driving through
standing water do not exceed crawl speed
of
4 mph (7 km/h).
• Always determine the depth before
attempting a water crossing.
• Proceed slowly and avoid splashing
water any more than is necessary. As
the water depth increases, vehicle
speed must be reduced to avoid
potential vehicle damage.
• Be aware that obstacles and debris
may be beneath the water ’s surface.
• Keep the doors fully closed during the
water crossing.
• Upon completion of the water crossing,
slowly drive a short distance and check
the brakes for full effectiveness.
SNOW PLOWING
Ford recommends that the Super Duty
F-Series used for snow removal include
the snowplow package option.
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 the vehicle
from the snowplow installer certifying
that the installation meets all
applicable Federal Motor Vehicle
Safety Standards (FMVSS).
• The Total Accessory Reserve Capacity
(TARC) is on the lower right side of the
vehicle ’s Safety Compliance
Certification Label. This applies to
Ford-completed vehicles of
10,000 lb
(4,536 kg) GVWR or less. This is the
weight of permanently-attached
auxiliary equipment, such as snowplow
frame-mounting hardware, that can
be added to the vehicle and satisfy
Ford compliance certification to
FMVSS. Exceeding this weight may
require the auxiliary equipment installer
additional safety certification
responsibility. The Front Accessory
Reserve Capacity (FARC) is for
customer convenience.
• 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
re-adjustment.

HAZARD FLASHERS
Note:
The hazard flashers operate when
the ignition is in any position, or if the key is
not in the ignition. If used when the vehicle
is not running, the battery loses charge. As
a result, there may be insufficient power to
restart your vehicle. The flasher control is on the
instrument panel. Use your
hazard flashers when your
vehicle is creating a safety hazard for other
motorists.
• Press the flasher control and all front
and rear direction indicators flash.
• Press the button again to switch them
off. FUEL SHUTOFF WARNING: If your vehicle has been
involved in a crash, have the fuel system
checked. Failure to follow this instruction
could result in fire, personal injury or
death.
Note: When you try to restart your vehicle
after a fuel shutoff, the vehicle makes sure
that various systems are safe to restart.
Once the vehicle determines the systems
are safe, then the vehicle allows you to
restart.
Note: In the event that your vehicle does
not restart after your third attempt, contact
a qualified technician.
The fuel pump shutoff stops the flow of
fuel to the engine in the event of a
moderate to severe crash. Not every
impact causes a shutoff.
Should your vehicle shut off after a crash,
you may restart your vehicle.
If your vehicle has a key system:
1. Switch off the ignition.
2. Switch to start position.
3. Switch off the ignition.
4. Switch on the ignition to re-enable the
fuel pump.
5. If the vehicle does not start, repeat steps 1 through 4.
If your vehicle has a push button start
system:
1. Press START/STOP to switch off your
vehicle.
2. Press the brake pedal and START/STOP
to switch on your
vehicle.
3. Remove your foot from the brake pedal
and press
START/STOP to switch off
your vehicle.

4. You can attempt to start the vehicle
by pressing the brake pedal and
START/STOP, or press START/STOP
without pressing the brake pedal.
5. If the vehicle does not start, repeat steps 1 through 4.
JUMP STARTING THE VEHICLE WARNING:
Batteries normally
produce explosive gases which can
cause personal injury. Therefore, do not
allow flames, sparks or lighted
substances to come near the battery.
When working near the battery, always
shield your face and protect your eyes.
Always provide correct ventilation. WARNING:
Keep batteries out of
reach of children. Batteries contain
sulfuric acid. Avoid contact with skin,
eyes or clothing. Shield your eyes when
working near the battery to protect
against possible splashing of acid
solution. In case of acid contact with skin
or eyes, flush immediately with water for
a minimum of 15 minutes and get prompt
medical attention. If acid is swallowed,
call a physician immediately. WARNING:
Use only adequately
sized cables with insulated clamps.
Preparing Your Vehicle
Do not attempt to push-start your
automatic transmission vehicle.
Note: Attempting to push-start a vehicle
with an automatic transmission may cause
transmission damage.
Note: Use only a 12-volt supply to start your
vehicle. Note:
Do not disconnect the battery of the
disabled vehicle as this could damage the
vehicle electrical system.
Park the booster vehicle close to the hood
of the disabled vehicle, making sure the
two vehicles do not touch.
Connecting the Jumper Cables WARNING:
Do not attach the
cables to fuel lines, engine rocker covers,
the intake manifold or electrical
components as grounding points. Stay
clear of moving parts. To avoid reverse
polarity connections, make sure that you
correctly identify the positive (+) and
negative (-) terminals on both the
disabled and booster vehicles before
connecting the cables. WARNING:
Do not attach the end
of the positive cable to the studs or
L-shaped eyelet located above the
positive (+) terminal of your vehicle ’s
battery. High current may flow through
and cause damage to the fuses. WARNING: Do not connect the end
of the second cable to the negative (-)
terminal of the battery to be jumped. A
spark may cause an explosion of the
gases that surround the battery.
Note: In the illustration, the bottom vehicle
represents the booster vehicle.
