If two adults and a child occupy a Regular
Cab, properly restrain the child in the
center front unless doing so would interfere
with driving your vehicle. This provides lap
and shoulder belt protection for all
occupants, and airbag protection for the
adults. A child or infant properly restrained
in the center front seat should not incur
risk of serious injury from the airbags.
SIDE AIRBAGS
WARNING: Do not place objects
or mount equipment on or near the
airbag cover, on the side of the seatbacks
(of the front seats), or in front seat areas
that may come into contact with a
deploying airbag. Failure to follow these
instructions may increase the risk of
personal injury in the event of a crash. WARNING:
Do not use accessory
seat covers. The use of accessory seat
covers may prevent the deployment of
the side airbags and increase the risk of
injury in an accident. WARNING:
Do not lean your head
on the door. The side airbag could injure
you as it deploys from the side of the
seatback. WARNING:
Do not attempt to
service, repair, or modify the airbag, its
fuses or the seat cover on a seat
containing an airbag as you could be
seriously injured or killed. Contact your
authorized dealer as soon as possible. WARNING:
If the side airbag has
deployed, the airbag will not function
again. The side airbag system (including
the seat) must be inspected and serviced
by an authorized dealer. If the airbag is
not replaced, the unrepaired area will
increase the risk of injury in a crash.
The side airbags are located on the
outboard side of the seatbacks of the front
seats. In certain sideways crashes, the
airbag on the side affected by the crash
will be inflated. The airbag was designed
to inflate between the door panel and
occupant to further enhance the protection
provided occupants in side impact crashes. The system consists of the following:
•
A label or embossed side panel
indicating that side airbags are found
on your vehicle.
• Side airbags located inside the
seatback of the driver and front
passenger seats. ·Crash sensors and monitoring
system with readiness indicator.
See Crash Sensors and Airbag
Indicator
(page 56).

TOWING A TRAILER
WARNING: Do not exceed
the GVWR or the GAWR
specified on the certification
label. WARNING:
Towing trailers
beyond the maximum
recommended gross trailer
weight exceeds the limit of your
vehicle and could result in engine
damage, transmission damage,
structural damage, loss of
vehicle control, vehicle rollover
and personal injury. WARNING:
Do not exceed
the lowest rating capacity for
your vehicle or trailer hitch.
Overloading your vehicle or
trailer hitch can impair your
vehicle stability and handling.
Failure to follow this instruction
could result in the loss of control
of your vehicle, personal injury or
death. WARNING: Do not cut, drill,
weld or modify the trailer hitch.
Modifying the trailer hitch could
reduce the hitch rating. Note:
To prevent your trailer from
accumulating distance, and the
trailer information status appearing
when you restart your vehicle after
disconnecting your trailer, you must
deactivate your trailer. Using the
information display, go to the
Towing menu and then the Select
Trailer option. Select the No active
trailer option. See
Information
Displays (page 112).
Your vehicle may have electrical
items, such as fuses or relays,
related to towing. See
Fuses
(page 318).
Your vehicle may have ability to
modify trailer towing features.
See
General Information (page
112).
Your vehicle's load capacity
designation is by weight, not by
volume, so you cannot necessarily
use all available space when
loading a vehicle or trailer.
Towing a trailer places an extra
load on your vehicle's engine,
transmission, axle, brakes, tires
and suspension. Inspect these
components periodically during,
and after, any towing operation.

•
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 is
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. Consult
your authorized dealer for additional
information.
Operating the Vehicle with the
Snowplow Attached
Note: Do not use your vehicle for snow
removal until you have driven at least
500 mi (800 km).
Ford recommends vehicle speed does not
exceed
45 mph (72 km/h) when
snowplowing.
The attached snowplow blade restricts
airflow to the radiator, and may cause the
engine to run at a higher temperature:
Attention to engine temperature is
especially important when outside
temperatures are above freezing. Angle
the blade to maximize airflow to the
radiator and monitor engine temperature
to determine whether a left or right angle
provides the best performance.
Follow the severe duty schedule in your
Scheduled Maintenance information for
engine oil and transmission fluid change
intervals. Snowplowing with your Airbag
Equipped Vehicle WARNING:
Do not attempt to
service, repair, or modify the airbag
supplemental restraint system (SRS) or
its fuses. Contact an authorized dealer. WARNING:
Additional equipment
for example snowplow equipment may
affect the performance of the airbag
sensors increasing the risk of injury.
Please refer to the Body Builders Layout
Book for instructions about the
appropriate installation of additional
equipment. WARNING:
All occupants of the
vehicle, including the driver, should
always properly wear their seatbelt, even
when provided with an airbag
supplemental restraint system (SRS).
Your vehicle is equipped with a driver and
passenger airbag supplemental restraint
system. The supplemental restraint system
will activate in certain frontal and offset
frontal collisions when the vehicle sustains
sufficient frontal deceleration.
Careless or high speed driving while
plowing snow that results in sufficient
vehicle decelerations can deploy the
airbags. Such driving also increases the risk
of accidents.
Never remove or defeat the tripping
mechanisms designed into the snow
removal equipment by its manufacturer.
Doing so may cause damage to the vehicle
and the snow removal equipment as well
as possible airbag deployment.

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. 1.
Connect the positive (+) jumper cable
to the positive (+) terminal of the
discharged battery. 2. Connect the other end of the positive
(+) cable to the positive (+) terminal
of the booster vehicle battery.
3. Connect the negative (-) cable to the negative (-) terminal of the booster
vehicle battery.
4. Make the final connection of the negative (-) cable to an exposed metal
part of the stalled vehicle's engine,
away from the battery and the fuel
injection system, or connect the
negative (-) cable to a ground
connection point if available.
Jump Starting
1. Start the engine of the booster vehicle
and rev the engine moderately, or press
the accelerator gently to keep your
engine speed between 2000 and 3000
RPM, as shown in your tachometer.
2. Start the engine of the disabled vehicle.
3. Once the disabled vehicle has been started, run both vehicle engines for an
additional three minutes before
disconnecting the jumper cables.
Removing the Jumper Cables
Remove the jumper cables in the reverse
order that they were connected.

Power Distribution Box
WARNING: Always disconnect the
battery before servicing high current
fuses. WARNING: To reduce risk of
electrical shock, always replace the
cover to the power distribution box
before reconnecting the battery or
refilling fluid reservoirs. The power distribution box is in the engine
compartment. It has high-current fuses
that protect your vehicle's main electrical
systems from overloads.
If the battery has been disconnected and
reconnected, some features need to be
reset. See
