2021 FORD F-450 air condition

designed to provide. If you choose to
deactivate your airbag, you are losing the
very significant risk reducing benefits of
the airbag and you are also reducing the
effectiveness of the seatbelts, because
seatbelts in modern vehicles are designed
to work as a safety system with the
airbags.
National Highway Traffic Safety
Administration Deactivation Criteria
(Excluding Canada)
WARNING: This vehicle has special
energy management seatbelts for the
driver and right front passenger. These
particular seatbelts are specifically
designed to work with airbags to help
reduce the risk of injury in a crash. The
energy management seatbelt gives or
releases additional seatbelt webbing in
some accidents to reduce the
concentration of force on an occupant's
chest and to reduce the risk of certain
bone fractures and injuries to underlying
organs. In a crash, if the airbag is off, this
energy management seatbelt might
permit the passenger wearing the
seatbelt to move forward enough to
have a serious or fatal injury. The more
severe the crash, and the heavier the
occupant, the greater the risk. Make sure
the airbag is on for any passenger who
does not qualify under the National
Highway Traffic Safety Administration
deactivation criteria.
1. Infant. An infant (less than 1 year old)
must ride in the front seat because: •
The vehicle has no rear seat;
• The vehicle has a rear seat too small
to accommodate a rear-facing infant
seat; or
• The infant has a medical condition
which, according to the infant's
physician, makes it necessary for the
infant to ride in the front so that the
driver can constantly monitor the
child's condition.
2. Child age 1 to 12. A child age 1 to 12 must
ride in the front seat because:
• The vehicle has no rear seat;
• Although children ages 1 to 12 ride in
the rear seat(s) whenever possible,
children ages 1 to 12 sometimes must
ride in the front because no space is
available in the rear seat(s) of the
vehicle; or
• The child has a medical condition
which, according to the child's
physician, makes it necessary for the
child to ride in the front seat so that the
driver can constantly monitor the
child's condition.
3. Medical condition.
A passenger has a
medical condition which, according to his
or her physician:
• Causes the passenger airbag to pose
a special risk for the passenger;
• Makes the potential harm from the
passenger airbag in a crash greater
than the potential harm from turning
off the airbag and allowing the
passenger, even if belted, to hit the
dashboard or windshield in a crash.

1. Infant: An infant (less than 1 year old)
must ride in the front seat because:
• My vehicle has no rear seat;
• The rear seat in my vehicle cannot
accommodate a rear-facing infant
seat;
• The infant has a medical condition
which, according to the infant's
physician, makes it necessary for the
infant to ride in the front seat so that
the driver can monitor the infant's

2. Child age 12 or under: A child age 12 or
under must ride in the front seat because: •
My vehicle has no rear seat;
• Although children age 12 and under ride
in the rear seat whenever possible,
children age 12 and under have no
option but to sometimes ride in the
front seat because rear seat space is
insufficient;
• The child has a medical condition that,
according to the child's physician,
makes it necessary for the child to ride

3. Medical condition:
A passenger has a
medical condition that, according to his or
her physician:
• Poses a special risk for the passenger
if the airbag deploys; and
• Makes the potential harm from the
passenger airbag deployment greater
than the potential harm from turning
off the airbag and experiencing a crash
without the protection offered by the
airbag
Proper Driver and Front Passenger
Seating Adjustment WARNING:
National Highway
Traffic Safety Administration (NHTSA)
recommends a minimum distance of at
least
10 in (25 cm) between an
occupant's chest and the driver airbag
module.
To properly position yourself away from
the airbag:
• Move your seat to the rear as far as you
can while still reaching the pedals
comfortably.
• Recline the seat slightly (one or two
degrees) from the upright position.

Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 202008, Third-Printing- Supplementary Restraints System

The restraints control module also
monitors the readiness of the above safety
devices plus the crash and occupant
sensors. The readiness of the safety
system is indicated by a warning indicator
light in the instrument cluster or by a
backup tone if the warning light is not
working. Routine maintenance of the
airbag is not required.
A difficulty with the system is indicated by
one or more of the following:
The readiness light will not
illuminate immediately after you
switch the ignition on.
• The readiness light either flashes or
stays lit.
• You hear a series of five beeps. The
tone pattern repeats periodically until
the problem, the light or both are
repaired.
If any of these things happen, even
intermittently, have the supplemental
restraint system serviced at an authorized
dealer immediately. Unless serviced, the
system may not function properly in the
event of a crash.
The fact that the seatbelt pretensioners
or front airbags did not activate for both
front seat occupants in a crash does not
mean that something is wrong with the
system. Rather, it means the restraints
control module determined the accident
conditions (crash severity, belt usage)
were not appropriate to activate these
safety devices.
• The design of the front airbags is to
activate only in frontal and near-frontal
crashes (not rollovers, side impacts or
rear impacts unless the crash causes
sufficient frontal deceleration).
• The design of the seatbelt
pretensioners is to activate in frontal,
near-frontal and side crashes, and in
rollovers. •
The design of the side airbags is to
inflate in certain side impact crashes.
Side airbags may activate in other
types of crashes if the vehicle
experiences sufficient sideways motion
or deformation.
• The design of the Safety Canopy is to
inflate in certain side impact crashes
or rollover events. The Safety Canopy
may activate in other types of crashes
if the vehicle experiences sufficient
sideways motion or deformation, or a
certain likelihood of rollover.
AIRBAG DISPOSAL
Contact your authorized dealer as soon as
possible. Airbags must be disposed of by
qualified personnel.

GENERAL INFORMATION
Condensation in the Exterior Front
Lamps and Rear Lamps
Exterior front lamps and rear lamps have
vents to accommodate normal changes
in air pressure.
Condensation can be a natural by-product
of this design. When moist air enters the
lamp assembly through the vents, there is
a possibility that condensation can occur
when the temperature is cold. When
normal condensation occurs, a fine mist
can form on the interior of the lens. The
fine mist eventually clears and exits
through the vents during normal operation.
Clearing time may take as long as 48 hours
under dry weather conditions.
Examples of acceptable condensation are:
•
The presence of a fine mist (no streaks,
drip marks or large droplets).
• A fine mist covers less than 50% of the
lens.
Examples of unacceptable condensation
are:
• A water puddle inside the lamp.
• Streaks, drip marks or large droplets
present on the interior of the lens.
If you see any unacceptable condensation,
have your vehicle checked by an authorized
dealer. LIGHTING CONTROL Lamps off.
A
Parking lamps, instrument panel
lamps, license plate lamps and
rear lamps.
B
Headlamps.
C
Headlamp High Beam Push the lever away from you to
switch the high beam on.
Push the lever forward again or pull the
lever toward you to switch the high beams
off.

Engine Oil Pressure Gauge
Indicates engine oil pressure. The needle
should stay in the normal operating range
(between L and H). If the needle falls
below the normal range, stop your vehicle,
turn off the engine and check the engine
oil level. Add oil if needed. If the oil level is
correct, have your vehicle checked by an
authorized dealer.
Engine Coolant Temperature
Gauge
WARNING: Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap
with a thick cloth to prevent the
possibility of scalding and slowly remove
the cap. Failure to follow this instruction
could result in personal injury.
Indicates engine coolant temperature. At
normal operating temperature, the level
indicator will be in the normal range. If the
engine coolant temperature exceeds the
normal range, stop your vehicle as soon as
safely possible, switch off the engine and
let the engine cool.
Fuel Gauge
Note: The fuel gauge may vary slightly
when your vehicle is moving or on a slope.
The fuel gauge indicates about how much
fuel is in the fuel tank.
The arrow adjacent to the fuel pump
symbol indicates on which side of your
vehicle the fuel filler door is located. Low Fuel Reminder
A low fuel level reminder displays and
sounds when the distance to empty
reaches
75 mi (120 km) to empty for
MyKey, and at 50 mi (80 km), 25 mi
(40 km), 10 mi (20 km) and 0 mi (0 km)
for all vehicle keys.
Note: The low fuel reminder can appear at
different fuel gauge positions depending on
fuel economy conditions. This variation is
normal.
Transmission Fluid Temperature
Gauge
Indicates transmission fluid temperature.
At normal operating temperature, the level
indicator will be in the normal range. If the
transmission fluid temperature exceeds
the normal range, stop the vehicle as soon
as safely possible and verify the airflow is
not restricted such as snow or debris
blocking airflow through the grill. Also,
higher than normal operating temperature
can be caused by special operation
conditions (i.e. snowplowing, towing or
off-road use). Operating the transmission
for extended periods with the gauge in the
higher than normal area may cause
internal transmission damage. You need
to alter the severity of your driving
conditions to lower the transmission
temperature into the normal range. If the
gauge continues to show high
temperatures, see an authorized dealer.
Turbo Boost Gauge
(If Equipped)
Indicates the amount of manifold air
pressure in the engine.
DEF Gauge
(If Equipped)
Indicates the current DEF level.
